I understand it is the replacement for the BK-117. I also thought they would have put a Fenestrom on it. Just been flying around in some EC-135s and the new tail is a great addition.

It doesn't have a fenestron because il est un BK avec some new bits sans un new tail which is pure BK. It is designed to keep down the development costs but to refresh the now ageing BK. Should be good but with a price kept lower because of the lower development costs.

I often wonder if they still have the original aerospatiale (Gazelle / EC135) and MBB (Bolkow / MB 117 / EC145) design engineers in suspended animation and bring them out for a new design concept, now and again.


Beautiful piccies...

Are the engines on the EC145 LTS's.? From the picture it seems as if its a smaller airframe. The one thing about the BK117 is that it is built like a brick 5hit house. Thats always a nice feeling.

Arent all the BK-117s being built these days (and the last few years) all powered
by Turbomeca ? I think so...BK-117C-1.
I bet the EC-145 are Turbomeca also.

Thanks Larry,

To be honest I wouldn't know. Most of the BK's in Australia including the one we operate have lycoming's. I am yet to see a 'new' BK over here, but look forward to it.

Thanks for your help.

I have heard that the EC145 is a NEW AGE BK 117. Does anybody know if they have actualy taken the BK fusalarge and worked around it or if they desinged it from scratch?

And what is it like to fly?Does the fusalarge leak when it flies through rain like claimed on the EC155?

I ask these Questions as I am doing some research on which Medium helicopter is the most suitable for long distance SPIFR.This includes time spent in Maintenance and speed.Preferably 140kts+.

From what I saw at Heli Expo the 145 has a larger cabin than the BK-117. I know that Westpac here in Auckland is looking at buying one next year to replace their BK, so will try and get their feedback.

Ok
EC135 + Bk117 = EC145
EC120 + AS350 = EC130
AS365n3 + new fuselage = EC155.

I have not heard much about EC135 leaking so I assume the EC145 would not.

I haven't flown EC 145 in rain, but i never met a really dry helo. But Flare Dammit! it would be clever, :eek: to make a time or rain-intensity specification!
May be on a virgin ship, rain stays out for a couple of hours :D :D :D

@ Dynamic Component

EC 145 cabin is 1,5 ft longer and 30 inch wider than aboard the BK117. Floor is flat and long awaited :) without any center or door posts. On both sides is an aditionally window. That means 2 seats more than BK on a 3-2-3 seats arrangement (club seating). Clamshell and lateral outsize doors like the BK. New age pilot area, very good pilot view, glass cockpit (no more right sliding on approach for better view!!! ), including SPIFR AP. MR blades of new design and some other improvements should decrease vibrations and noise level and adds some pounds more gross weight (now 7830 lbs). Usable fuel (standard configuration) is 1525 lbs + 396 lbs long range fuel. According to the payload/range chart, up to 1800 lbs payload + 1 pilot, the ship can reach 360 NM standard and 440 NM long range. Cruising speed is 130-135 kt. VNE on max. gross weight 145 kt. If you like BK's handling and characteristics, (rigid rotor) the new ship could be right for you. At least i like the craft. EC 155 (deicing is coming) is an other class or take a view to Ft. Worth. A109 Power is faster but on max. fuel you have to fly alone with your boss. But you know, comparing helos is impossible. There are so much point of views and i get my money for flying! :rolleyes:

18th Jul 2002, 22:52
I was quite impressed with the external noise level on the 145 probably about the same as the 155 which has benefit of the fenestron at higher GW. Those tapered blades make a huge difference.

Best agrument for the 145 instead of the 155 is the 155 itself as I hear. Next best agrument is the lack of support to the owner/operator by the French side of Eurocopter......and yes....wear your wellies and carry a brolly in rainy season if you fly the 155.

Heard that Shell Nigeria arent too happy with their new purchases according to some little birdies from that area. ;)

Maybe some of our African visitors can elaborate on that one a little more.

DC - Talk to Childflight also as they have an N2 I think and are having some teething problems with it. Seems they added a lot of mods to it and now there is a pain in the ass vibration that wont go away. That info is not firsthand but worth looking at. Terry M would be the best person to give you first hand info.

On the other hand Vic Pol seem to be very happy with their N3s.

Autorotate,

I know the one you're talking about.I've seen Childflights Dauphin on the ground more than in the air.I've spoken to Eurocopter and what you say is apparently exactly the problem.Vibrations in flight.The first problem was to do with the yaw system on the autopilot.

Apparently it is a awesome machine though.It can do 160 kts with 2 onboard and half fuel.

19th Jul 2002, 09:48
The Dauphin is a good helicopter for medium range SPIFR. It is reliable and cheap to maintain. The cruise speed would depend on what part of the world you would be operating and what weight you wanted to operate it at (N. Europe around 140 knots, tropics around 130 knots realistically speaking).
Shell have been having some problems with their EC 155s in Nigeria. From what I hear a lot of them are no different from the teething problems almost any new type has in its early days. The main complaint is probably to do with actual single-engine performance as opposed to claimed single-engine performance. The Arriel 2C1 is basically pretty much the same engine as the Arriel 2S1 as fitted in the S76C+ and most operators of the latter type in hot climates have been having a lot of problems with engines failing power assurance. Supposedly the Arriel 2C2/2S2 will address most of these problems, but that remains to be seen.
I've yet to fly a helicopter that doesn't leak in the rain.

The EC145 is certified as the BK117 C2. This allowed Eurocopter/Kawasaki to keep the certification costs to a minimum. You might be interested to note that as a result of this EC were able to use the large screen by applying the regulations in force at the time of the certification of the BK117, the screen does NOT conform to birdstrike criteria in force at the time of the certification of the C2; this has been a sticky point with the CAA.

As an aside, the choice of a plank wing IFR FMS for a helo destined for a lot of SAR and police work was not wise. Try it and see.......

I'd love to trade my 117 for a 145, the improvements all appear to be the result of listening to the customer. Difficult to believe Eurocopter would be capable of such a move :rolleyes:

At the risk of spooking the weather gods, in 5+ years operation my 117 has yet to leak in the rain, in flight or on the ground. And all the panels still go back in the right place without persuasion; German and Japanese standards at their highest, IMHO.

I remember the astonishment shown many years ago, when the VicPol introduced new radios and we asked for motorcycle control heads for the Dauphin, since they were already waterproofed. The radio techs actually thought we were joking :cool:

Eurocopter has sold its first EC 145 in the United States to the Lee County Division of Public Safety/EMS.
Lee County, which lies along the west coast of Florida, includes the city of Fort Myers and 652,000 acres of coastal area and barrier islands.
The EMS is responsible for providing advanced life support for out-of-hospital emergencies and primary health care and also responds to personnel searches, mass casualty incidents, and missing or downed aircraft reports.
They've been operating helicopters since 1978, and currently fly a B0-105. Delivery of the EC 145 to Lee County is slated for early 2004.

Well whadya know!

Calling EC145 operators worldwide

It fits my mission profile from the persepctive of size and carrying capacity.

Any body got any feed back on this helicopter from the handling characteristics perspective.

I have heard particualrly from the French that the helicopter does not handle well in confined areas, lack of tail rotor authority, very rigid ride, not good in the mountains. OK, So its not an Allouette III.

I am also very interested to know how the mainteance load is viewed for technicains and its suitability to remote operations.

Is the current lack of FADEC control a real issue.

Would it be OK for VIP passenger transport, does it roll like a pig in the wind. The flights are always short hops.

Thanks.

Interesting question/ topic....... I thought that the EC145 was really just a growth version of the BK117 ...and as such would have EXCELLENT confined area handelling qualities ...( but maybe not at 10,000ft !!) ..... certainly the BK does ...must watch what is said closely ...

Are the CAA the only regulatory authority concerned about the fact that the 145's controls run through flexicables up the central front windscreen frame? I know they've expressed reservations about birdstrike resilience.

PANews
13th Sep 2003, 07:30
I have asked about the rumours that the flying qualities of the EC145 were being 'knocked' by French pilots newly introduced to it.

The standard reply [albeit suspect because it is an EC source] is that the high time pilots are comparing their long experience with such as Alouettes ['seat of the pants flying'] with the high tech new technology 145. The difference between the two is vast. It is an age old observation - the same as expressed by those in open cockpit bi-planes transferring to enclosed monoplanes I guess.

The most likely exponent might be someone with BK117 experience apreciating the added value of the upgrades machine. The same type of criticism was heard from those moving from the Lama to the AS350B3 ....... but it sells.

John Eacott
13th Sep 2003, 09:35
I can only comment on the handling of the BK, but I'd love to be able to afford/justify the upgrade to a 145 ;)

With the C model tail rotor blades, the "lack of tail rotor authority" is almost a none event. At max. gross, high DA, it will need a bit of care as would most other machines, but the TR thrust is there, and effective.

Rigid ride? Well, it is a rigid rotor design, and certainly handles the turbulence more like a fixed wing than a "conventional" articulated head helicopter, but you can use that ability to fly in areas that you just wouldn't take a "conventional" machine. Not if you want to fly out in one piece, that is!

Confined areas? The 117 is superb, if you can fit in a Squirrel, you'll land a BK, often with more confidence and safety. High tail rotor, two donks, small rotor diameter, good power reserves.

High altitude: the 145 has better engines & performance, so I'd expect it to outperform the 117-B2 that I have, which we use to land at 6000ft on a daily basis, with 8 skiers and their equipment. The roof top pad we have is a gridded deck, with no ground cushion as a result, but the BK handles that well.

FADEC: nice to have, but not exactly critical to the machine's capability, surely?

Maintenance: we have surged through remote fire operations up to 12 hours/day, and kept going with commendable reliability.

VIP transport: the short tail boom can induce a semi Dutch roll, if not handled well. CSAS will help against this, or a boot full of opposite yaw to stop the PIO :ok: The enlarged door opening of the 145 should make VIP passenger access easier than the 117, which has a relatively small sliding door, and subsequent difficulty with entry around VIP seats.

The French have a degree of difficulty with the 145, since it slots into the sales market against the 365N/155. As the "home grown" machine will naturally be considered superior, a degree of parochialism may need to be allowed for ;)

Hope that helps....

I spent a day with the Lausanne based Rega 145 and according to Laurent Racine, who I spent some time talking to, it is a great machine. He said it is very smooth and even though it doesnt have the FADEC system it is still the same to manage as the BK, in fact it is easier.

Some of the areas they go into are confined and he said that they have had no handling issues with it, and he compares it the same to the BK, with the added advantage of new cockpit, moving maps etc etc. The only negative thing he said was when it was in a high alt hover with a lot of wind it did get kicked around a bit more than a BK, but having never flown one cant really say much more than that.

I have plenty of images of the insides of it if you want them posted here, including panel shots with everything up and running.

P.S. The French Securitie Civil lost a 145 not long ago when it struck some rocks.

@ touareg

The EC 145 is approved as a new version of the proven BK 117. But differencies between the older BK 117 B2 or C1 and the new ship are much greater than on any other BK series.

At the moment not so much ships have really enough (real missions) flight hours for a final comment.


John Eacott :ok: describes the BK 117 B2 and C1 models and their handling and servicing characteristics very well. The differencies to the EC 145 are not so big.

What's now the EC 145:

1. We have the same engines like the C1. That means no FADEC and 2 min cooling time. But the new MTOW is now 3585kg/7,826lbs. :yuk:

2. We have an improved main rotor. Should provide a little more lift.

3. The greatest step forward is the new cockpit layout with the new "MEGHAS" glass cockpit. That's really the best on the ship (my opinion) because of the much more better pilots view outside. But the new glass cockpit could give so much indication possibilities, so much informations and require therefore much more knowlegde from the pilot. That's the big big difference to the older ships. On the differential training is the biggest point to teach the pilots the needed cockpit skills especially on emergencies. It's the first time in my pilots-life that i have heard from older pilots: that ship isn't the right thing for my last years, because of the complete new avionic and cockpit generation. Including a new very good autopilot (fully automatic ILS Approach up to 65ft), the ship should allways fly with the AP engaged.

4. More fuel and increased endurance (2,5h).

5. As said with the old engines and the new MTOW is especially the OEI performance not so good. :ugh: Short: the ship is nearly allways underpowered. To reach CAT "A" performance under operation conditions it seems impossible to take the advantage of the more payload and fuel.

6. The rear cabin is larger. (Really good)

7. A new hoist without the big older boom direct above the sliding doors. (booth sides possible) that means improved hoist capabilities.

The ship is very good to fly (of course a rigid rotor) and as good as the older BK's on confined areas. But absolutely shure it's not a hot and high helicopter. The "flexicables" working good and the ship is new for Eurocopter ships equipped with twist grips.
As a new ship with not so much flying time the maintenance load is difficult to describes. That's a question of the next 2-4 years.

And at last: the thing is really (maybe to) expensive to buy. :* I'm not shure if it is possible to buy and to fly the EC 145 on free market and business conditions at the moment worldwide. Have heard, you have to expect delivering times up to 2 years.

13th Sep 2003, 21:18
Can't comment on the specific questions first made, but to follow up on the last remarks: I fly the EC-155 and have to say that the Avionique Nouvelle cockpit is superb. It is hard to imagine a more pilot friendly environment, especially for SPIFR.

tecpilot
13th Sep 2003, 21:50
I fully agree to 212man. The point is the pilot must be able to use the possibilities of the glass cockpit. And there are a lot of procedures in case of an indication or equipment failure.

Anybody have any time in the EC-145? We are looking at potential aircraft, and am wondering how it would compare to a 109E. I'm sure the speed doesn't match up, but we are looking more at volume then speed. IFR is a must, as is a convertable interior from pax to light cargo. Also looking at an S-76, but am thinking it's overkill.

John Eacott
4th Feb 2005, 02:42
I suspect that is a major headache for Eurocopter, since they have produced in the 135, a competitor for the 145 (which is a development of the BK117C).

I'd still like to be able to justify one......:cool:

Hippolite
4th Feb 2005, 04:03
The EC 145 is really a BK117C with a 135 "front end" on it. EC did a great job in removing the control closet and running the controls through the centre winshield fairing.

I flew one a while ago and actually preferred it to the EC155. 8 pax and a totally move around and flexible interior make it an excellent small offshore, big EMS type machine. Almost a 412 competitor in my opinion. Cost is about $5mUS with SPIFR package fitted.

4th Feb 2005, 11:58
Hippolite, at least you said almost a 412 replacement, still stuff all payload , power , range and room compared to a 412EP and the Eurotrash don't like high ambient temps /hot high (not european hot ie: 25oC) real hot high 35-45 oC like Mid East and Australia

10th Feb 2005, 15:58
Blackhawk9,

You might wanna compare BK117 with S-76 at Karratha. Last time I was there, BK would leave 76 for dead during summer (A while back I must admit). Well known that even the older LTS101 BK's have more than enough power, let alone the newer Arriel 2 powered versions!! Not all European helicopters are anaemic, and not all yank tanks have power to spare. Horses for courses.

Hippolite
10th Feb 2005, 20:43
blackhawk 9

Aa nooby says, horses for courses. I don't think that the 412EP would be any better even in your hot climate than the 145.
FYI, I am not in Europe.

The cabin in the 145 is more versatile than the 412EP although not quite as big. Remenber, the 145 is a smaller helicopter but for SOME missions, it would be a 412 EP competitor.

The 412 was good in its day but let's face it, its an old machine now with a limited life.

I think that you will see more 145s in your country, some even replacing or taking work from old 412s where the "voluminous" cabin of the 412 is not really being used to its full capacity.

HH:cool:

407 too
21st Feb 2005, 18:57
we are going through the process of deciding whether this machine warrants further consideration from us. (read as spending money to actually go to a different country to test fly)

i would like to ask you ec-145 drivers what you feel are the good/bad points with this machine

the numbers look fine for our utility type missions, BUT, what is the ride like for exec transport ?? My understanding is that EC has changed the blade design to help quiet and smooth the ride, and added a vibration dampner. is the translational buffeting anything i should be concerned about (exec transport) ??

what REAL numbers are you getting at say 7200 lbs for airspeed ??

what is the stability like in gusty 10 - 25 kt winds, bags all around required ??

we are now flying a 407, so the ride/speed issue may play a great part in our decision


and no, we are not relying on these responses to make a final decision, just to get some feedback from people actually flying the bird :ok:

Eurobolkow
22nd Feb 2005, 17:30
Its a 117 in disguise!!!!

No seriously just beware that its a utility aircraft that is not capable of producing the soothing cabin ride, environment or speed of an AB139 or Agusta Grand (to name but two).

Also no FADEC is a concern to many potential operators.

22nd Mar 2005, 15:10
Is the EC145 certified for doors-off flight?

I'm hearing that the doors must be kept closed as they are critical to the cabin structural integrity ... especially in relation to crashworthiness.

Anyone know?

Thanks for your help!

22nd Mar 2005, 18:36
Brasky,

The 145 FM Supplement Section 9.1-2 permits operations with a mix of crew and cabin doors open or removed subject to the usual limitations such as sideslip etc and your crosswind limit is reduced to 30 Kts. All seems pretty much standard.

STL

23rd Mar 2005, 11:04
I am aware that the front-crew doors have a semi-open position of say 100mm which provides a wind-break/spoiler action over the open main-cabin doors.

It would appear that the design team have been attentive to the needs of a demanding first customer or two - the French MOD and the Civil Rescue Authorities.

:D

Thomas coupling
23rd Mar 2005, 11:07
This might be relevant:
the EC135 cannot fly Class 1 (Cat A) with the doors opened.

Much the same reason I would assume - integrety of the cabin.

helmet fire
24th Mar 2005, 09:29
tc,
I am guessing that the doors will not restrict CAT A due to any structural reasons, but rather from excess drag causing reduced climb and acceleration performance. For example, the BK117 actually reduces it's climb performance by a staggering 250 ft per minute for doors open, so if you are heavy and OEI, taking 250 fpm off you is likely to be severley embarassing, and thus its a good thing to remember for rescue crews who have a donk failure: close the doors as quick as you can!

Thomas coupling
24th Mar 2005, 12:36
It also relates to the rear sliding doors!!!

No resistance there?

helmet fire
24th Mar 2005, 16:49
tc,
yep, that also relates to the rear sliding doors. The airflow disturbance around the fuselage caused by the big open hole is enough to incur the climb penalty.

tecpilot
25th Mar 2005, 07:11
helmet fire is right. There are some aerodynamic causes limiting the airspeed and the performance. Greater airspeeds with removed doors could go up to problems controlling the bank of the a/c. Due to the greater drag and the influence of the changed airstreams to the main AND tailrotor, the performance isn't as good as with doors closed.
Cat A with opened / removed doors is also not certified on BK 117 and EC 135.

Integrity and chrashworthiness of the cabin is is abolutely given also with opened/removed doors. There is a carbon frame on EC 135/145 giving the structural integrity. The doors doesn't have structural influence.

metric - for what it's worth, sounds like the same mod that's available to the 135, a new front door strut that (with a selector) restricts the door from opening fully, acting as a spoiler for the rear sliding door. In the case of the 135, your front door also gets re-inforced down the trailing edge but the overall package allows flight to 110kts, rather than the usual 60kt limit, with the sliding door open.

re my last post:

Sorry tc about the time delay.

the FM for the BK117 does include the climb rate issue. under Supplement 11-3, Operation with Doors removed, para 5.2 rate of Climb
"Subtract corection value as indicated below from the rate of climb obtained from the applicable performance chart of basic flight Manual.

Gross weight (kg): ...............ROC Correction (Ft/min):

1700 - 2200 .....................450

2200 - 2850 ......................350

2850 - 3350 .........................250"


As the doors open ROC correction reduces with GW, it consistent with aerodynamic reasons (actual ROC reduces with GW, and drag is exponential, therefore correction reduces accordingly).

The BK117 also has a statement in the CAT A supplement that with doors open/removed, the aircraft is not certificated for CAT A. Cat A is only available in the B2 to 2900 kg, so removing around 350 ft/min due drag of the open doors will cause the aircraft to fail to meet the CAT A profile.

I think!

According to Turbomeca the Arriel 1E2 engines couldn't be upgraded with a FADEC and Turbomeca isn't interested in major modifications on this "old" engines. And FADEC-ing is the part of the engine manufacturers not ECD.

It's right there are plans to upgrade the EC 145 on the next development level with a 5-bladed rotor, new MR Gearbox and FADEC equipped engines.

Just ask the maint. engineer to definite the therm "soon" ...

As always asking a vague question will get a vague answer or in this case probably a misleading one. Take whatever figure you are given by the EC PR boys here and add at least 10% for anything like a half decent spec.

Then the real question is how much less is an Agusta Grand!!!;)

As Eurobolkow emphsises, your question is without substance.

You will need to contact your local Eurocopter dealer and thrash it through with them adding all the bits and peices that you require including paint and interior and expect a big cost difference between the basic spec (airframe, engine, transmission and basic instrumentation) and the final fly away cost. The Agusta looks more expensive initially but the end cost needs appreciating.

Hello all,


okay, here it goes, "I know someone who knows someone" who plays with the idea to aquire a VIP/Corporate EC135. My interest is to get into this ship!
I do have the slight hope to get involved into the decision making process for the final-order-specs as well.
Knowing that VIP ships get rather heavy by the time they are done, I am entertaining the idea to suggest a EC145 instead, IF the requirements for transport go beyond the 4-seat VIP-135 version (4 in the back one on the co-pilot seat).

Money is always a question, but in this case it is secondary.
My concern is to be able to use full fuel at most all times, even thinking about the removable aux-tank (Long distance between available fuel stops).

Basic question is:

Are there ANY EC145 or BK117 out there in a VIP/Corporate configuration? I am talking leather/bar/satphone/pop-outs/etc.

These people are rather set for EC, however I appreciate any and all suggestions (at this time you are only bringing ME up to speed in the VIP helicopter world!)

What is your take on the idea of a VIP-EC145?

I have all the EC-info on the 145, there is no VIP interior like the 135 available, so I also appreciate hints towards companies that could transform a basic 145 into a VIP-transport!

I do have some questions to the EC-135 in this role too, but I will start a new thread for that or hook on the existing 135/355 discussion. However first I would like to wait for your response to this here!

Thanks to all in advance!

Roughly speaking more lift, hence higher MTWA

NickLappos
1st May 2006, 02:47
Frankly, there is no more lift or thrust in 5 vs 4 or 3 blades, as long as the total solidity of the rotor (total blade area divided by the total disk area) is the same. In other words, 4 skinny blades have no more lift than 3 somewhat wider blades. More blades usually weigh more, so that for the same solidity, a greater number of blades can reduce payload a bit, but the vibration is a bit smoother (especially when going from 2 to 3) with more blades.

212man
1st May 2006, 04:26
4 to 5 seems to make quite a difference too!

There must also be cost and maintenance issue involved; by definition a 5 bladed head must be more complex, cost more and the blades themselves will cost more, relative to a 4 bladed design.

NickLappos
1st May 2006, 09:33
Very true, and also the cost to make 1 blade is the sum of a fixed cost (inspection, paperwork, tooling, etc) and a variable cost (materials and labor) so that a 5 bladed head with blades must cost at least 20% more than a 4 blades head.

The vibration goes down by a ratio of the 2/3 power of the number of blades, so that the difference between 1 and 2 blades is enormous, 2 to 3 is big, 3 to 4 is less so, and so on. By the time you get to 7 vs 8 the number is too small to count.

topendtorque
1st May 2006, 10:04
"so that the difference between 1 and 2 blades is enormous"


Yep!

semirigid rotor
1st May 2006, 10:28
If I am reading this right, if the 5 blade option is too expensive / complex and little to be gained, could this be why ECD have gone for a "CAT A" switch on the EC135T2? Increase the RRPM by 3% for class 1 take off / landings and get the benefit of increased lift with a greatly reduced cost implication.

Now the EC145 comes with an automatic increase if RRPM at low speed (below 55Kts I believe), so why keep going down the extra blades route?

quichemech
1st May 2006, 10:34
Thanks nick, I should have gone a little more in depth with my answer, just trying to keep it simple.

widgeon
1st May 2006, 12:30
I have not had a close look at the 145 head , is it essentially the same as the Bk117 ?.

Just checked EC45 site ,it looks identical to BK117.

I think a key sentance in the press release is "sponsored by the German Ministry of Economics and Technology" The easy blade fold feature looks useful .

Back to Nicks earlier replies , why would any Sikorsky have more than 4 blades then ?.

And just to nit pick Nick missed out one element which is Non Recurring cost ( engineering and tooling ) this unit element will be reduced ( by a small amount ) per blade if you are making 20% more blades.

NickLappos
1st May 2006, 14:20
widgeon,
You seem to think that I say 4 blades is "better" than 5 blades, which is not true, at all! The 5 blades are more expensive, but could be a better mix when all design factors are considered. Obviously, Sikorsky thinks so,too. I have hundreds of hours in a 7 bladed monster!

semirigid,
You hit the nail on the head! Increasing rotor rpm is a way to add extra equivilent blade area without adding any blages. In effect, the rpm makes up for the lesser blade area, so that thrust is increased without any rotor head/blade change (as long as the CF can be tolerated.)
The peak thrust of a rotor is basically determined by the Ct/sigma (coefficient of thrust/solidity), where all rotors are limited to a set value of max Ct/Sigma (usually about 0.20). Ct is thrust/ [(air density) x (disk area0 x (tip speed squared)] and solidity is [(number of blades) x (chord) x (radius)]/ rotor disk area.

Sounds complicated, but it is basically just like an airplane wing, where the wing stalls at a fixed coefficient of lift, so you need either more wing area (rotor solidity), or more forward speed (rotor tip speed).

slowrotor
1st May 2006, 14:50
Is an odd number of blades such as 5 better than 4?

NickLappos
1st May 2006, 15:05
slowrotor,
No not at all, the more the number of blades, the smaller the humps in lift each create, and the higher the frequency the N/rev vibration is. Both factors make the greater number of blades a better vibration case. If the rotor had infinite blades, there would be no vibration.

212man
1st May 2006, 23:55
I think that the notion that EC use an increased Nr for their vertical Cat A profile to increase lift is a slight misconception. Although not denying the facts as stated by Nick (obviously they are correct) in the case of such profiles the weights are so restricted that lift, per se, is not the issue; it's rotor energy.

EC us the high Nr to increase the rotor energy for both the rejected take off and continued take off cases. In the former case, it allows the high rates of descent, that develop from a reject close to TDP, to be arrested, and in the latter case it helps minimise the drop down following a failure immediately after TDP.

In the case of the EC-155 it is the rate of descent in the rejected take off that is limiting the maximum TDP to 100 ft and the RTOW (1000 ft/min is common).

By using the increased Nr, they are also able to modify the HV curve and this allowed them to develop the 'increased slope' (short field in plain English!) procedure, whereby the a/c is allowed to start climbing sooner than would be the case with normal Nr. Similarly, it helps bridge the 15 kt gap between TDP and Vtoss. It is also a requirement for the offshore PC2e procedures they were developing last year.

By way of an example of the difference, I used to demonstrate failures in a 6 ft hover with normal Nr vesus at 10 ft with increased Nr, with no collective input, to illustrate the benefit. In the first case the low Nr audio would sound before ground contact, in the second case it would only go off once collective was applied to cushion the touchdown.

spinwing
2nd May 2006, 00:52
Perhaps they know that the "Old Lump of Titanium" has reached the end of its development life and there is a better way .... I think the present head design whilst great back in 1976 will not allow the A/C design to progress either due to retreating blade stall issues (read "cruise speed increases") or vibrations in flight ????

Cheers ;)

semirigid rotor
2nd May 2006, 10:47
Thanks 212 man, I have been looking for an explanation for this modification to the T2 series for a while. Even the test pilot forum went very quiet when I mentioned it!

Having said all that, the RRPM increase is just 3%, does it really make that much difference? I suppose ECD thinks that it does, but it sure is a complicated method and not without controversy. I think we are back to Nick's old chestnut about "percieved risk" - take your hand off the collective to press a button, just incase you have an engine failure or leave you hand the collective just incase you mess up the approach.

If the engineering could take it, would it not have been better to have increased the mass of the blades and thereby slow down the rate of RRPM decay?

NickLappos
2nd May 2006, 12:03
The stored enegry is proportional to the square of the rpm, so a 3% increase in rpm is actually a 6% increase in energy. It is not enormous, but it truly helps in Cat A and H-V engine cuts. For a hover cut, rotor energy is worth about 1/3 of the means to land, and engine power is worth about 2/3. So if we make a 6% increase on the 1/3, that would help increase Cat A weight by perhaps 2% total. For a 6000 lb machine, that is 120 lbs.

I think 212man has it right.

slgrossman
2nd May 2006, 13:01
Nick,

Notwithstanding the weight gain, wouldn't the addition of a fifth blade allow all the blades to be made closer to the ideal shape for hovering (long and narrow), while preserving the solidity necessary for high-speed and maneuvering performance?

Additionally, wouldn't the addition of a fifth blade allow all blades to operate at a lower angle of attack, thus increasing the retreating blade stall margin?

As to the vibration, do additional blades actually reduce the energy of the vibration or just shift it to a frequency which is less objectionable?

-Stan-

Aser
2nd May 2006, 17:42
I agree with 212man , we have the 102% switch on the collective for Cat A in the 139 and you are required to put 103% rrpm manually in the 412 for Cat A.

NickLappos
2nd May 2006, 19:31
Stan, your basic premise is just a little off - remember, it is not the number of blades that determines the total thrust, it is the solidity. All the virtues you list are attainable by controlling solidity. An additional blade is one way to get more solidity, another path is to provide the original number but with somewhat wider blades.

Regarding the vibration, the basic energy (actually the root shear forces) are very much reduced when you have more blades, and the reduction is much faster than linear, so it really helps to reduce vibration by adding blades.

semirigid rotor
3rd May 2006, 08:30
Thanks Nick, it now starts to make sense, with the formula for stored energy and 212 man's explanation. Wouldn't it be nice if the manufacturer's put a little bit of background information in the systems description of the aircraft flight manual?

As I understand it , the ratio is usually 6-1.

That is 6 rotations of the tail rotor for every 1 rotation of the main rotor, but I am not sure if that is the case for all helo's.

For the Notars.....erm ????? :confused:


Does anyone know of any helos where this is not the case... 6-1 rule?

HF

NickLappos
6th Aug 2006, 22:02
HELOFAN,
There really is no rule about ratios of rpm, but many times the tail rotor tip speed is the same as the main rotor (when a conventional open tail rotor is used), so the ratio of the rpm is often the ratio of the diameters of the two rotors. Many rotors use a tip speed between 700 and 725 feet per second. For the EC-145 that turns out to be a 6.5 to 1 rpm ratio.

HELOFAN
6th Aug 2006, 22:07
Thanks Nick.

I should say that the word "rule" was a term I was using loosly and should have said average is around.

Do you know where the ration of about 6-1 isnt correct?
I was thinking for multi tail rotor helo's such as the Apache or possibly the larger or smaller helo's come into play.
I would think it should not matter but I had to ask.

Thanks again.

Svenestron,

Yes I believe it is to reduce the interaction between the tip vorticies but it has been a looooong time since I went to school on that machine so I wouldn't swear it to be true. I can say that the sound is much lower frequency and amounts to a low hum, much quieter than the unit on the blackhawk which is about the same size aircraft. Not only are they space apart axially but they have an odd phase angle separation (the blades are not all 90 degrees apart). This may have as much to do with the low noise as anything else.

I'll be interested to see if the B model EC145, whenever it comes, will have the fenestron tail on it. I don't think the machine has much of an issue with tr performance as it is so any change to the fenestron would most likely be for noise reasons only.

Struggling to get a quick answer to these two, so if anyone sat with a manual in front of them (like wot I always have!) can you answer:

1. Does 145 have FADEC start up similar to EC135. If not I take it its not a hassle getting it started quickly for police / HEMS role?

2. Has anyone got any experience of air con fitted to 145 and would it cope ok with +40 c temps and a long soak in the sun?

thanks, :confused:

EC145 doesn't have FADEC, but is expected to get it's way into 145 with an upgraded model called "145 plus" by eurocopter training personnel.
I've talked to some pilots about the no-FADEC issue and the pilots that fly 135, really miss FADEC in 145.

maxtork
30th Jul 2010, 15:22
EC145 starting is not by FADEC as stated previously. It is basically like starting an AS350 B2 but it has the throttle on the twist grip and a magnetically held start switch that lets go after about 40% N1. Starting can be challenging at times. Each FCU is slightly different and each aircraft is rigged just a bit different and you have to modulate the throttle to get it going. Normally it is a non-issue and things start just fine but if you have a problem it can beat you up pretty bad trying to figure out exactly what it is. As for starting quickly I don't see it as being any slower than any other twin.

As for the air conditioning it seems to do well even in the high heat areas. In the southern CA desert it gets up to 50 C and the AC still works. Now will it make it cold enough at those temps to hang meat in the cabin? probably not but it will at least make it reasonable enough to survive.

Hope it helps

The 1st start and 2nd start are no issues, even starting within 20 mins of shutdown presented no problems (following the checklist and obseving the FLI [first Limit Indicator]).

I have flown one in the north of Aus with a after market aircon fitted - "Metro Aviation Air Conditioning".

You could feel cold air if you placed your hand over the vent, but when kitted up with full flight gear and a cabin as big as the 145 IT DID NOT CUT THE MUSTARD.

Reports are that Metro are working on a mod to improve the airflow (capacity).

In saying that, it was better than none at all as the inlet vent for ambient air is only about a 4inch diameter.

Overall, a very good pilot machine.

tecpilot
15th Aug 2010, 13:29
Yep, i heard the same. The 5-bladed rotor EC testet a few years ago is not in a serial condition.

And, it needs much more than a nearly original EC135-tail to bring the 145 to a new life.

The fan takes a lot of power. Not sure a the moment how EC will solve that problem. Stronger engines needs new gearboxes. Engines and improved gearboxes enhance the weight.

I hope not to see a new unlucky hybrid from EC with old engines and gearboxes but fan. That means bad flight performance.

Mmmm ...

Perhaps the tail boom construction will be stronger ... and with no t/r g'box pylon (cracking) inspections necessary ?

I hope the Fenestron has more yaw authority than the T/R system has!

Well from what I have heard this COULD be a good thing. The engines really aren't the limiting factor until you start to get up in altitude as you are torque limited until you get up there. I have heard that the weak link is not the main gearbox but in fact the intermediate gearbox which would be replaced by the fenestron. So this mod may allow more power from the engines to be used at lower altitudes should EC decide to certify it this way. Also most of our 145s are nose heavy so I don't know how the weight and distribution of the fenestron compares to the original tail rotor. Would be nice to eliminate one gearbox and push the weight a little further aft to help the CG. Based on the picture posted the tailboom is in fact different as it does not have the omega channels on the outside. One would expect it to be stronger. If this is the case then maybe they will be able to allow doors off ops now. I am told that this is currently not a good idea because the turbulence from the cabin with the doors off acts on the tail boom too much and drastically shortens its life. With a stronger boom maybe this is not the case anymore? Not that most EMS aircraft need to fly doors off but it would make the aircraft more suitable for other missions.

We shall see!

Hi!

I too have a quick question to the EC145..

If I am flying it, then land and want to stop the rotor with retained hydraulic capability, this would be doable, right?
--> I use rotor break but keep the engines on "ground idle" or something like that, right?:confused:

I'm trying to solve a 'blade folding' "problem", on a new system, that currently insists on producing/forcing stupid equipment that I don't believe to be necessary..
What I need to know is that you CAN use cyclic and collective "stick" on ground, after flight, while the rotor is not turning. ie. that hydraulics can be kept "online" after the rotor has stopped turning..

Thanks in advance for answers to this stupid question!
And, for the record, I'm not a pil!t

(There are no stupid questions, only stupid people..:})

maxtork
6th Sep 2010, 22:43
If I am not mistaken the hydraulic pump is drive by the main gearbox so if the blades stop turning then so does the pump. I think there may be an accumulator in the system but that will supply limited volume only. It is not permissible to stop the blades with the rotor brake with engines running. In fact I don't know if it is actually strong enough to do so in the first place and as stated above it wouldn't help you since the hyd pump is driven off the main gbox anyway. That being said you still can move the cyclic and collective without the hydraulics but it requires a bit more effort. Depending on how much you need to move the controls it may still be possible without hydraulics.

Hope it helps

Svenestron
6th Sep 2010, 23:41
Good answer Max, that helped me a lot.. :=
OK, not your fault that hydraulics are driven by the MGB..

But.. to continue.. could one say that, after landing whilst the MRB are slowing down and the MGB is still producing "some" pressure, it would be possible to perform a full cyclic movement at a time where ther is "enough" hydraulic pressure and the helicopter would not "keel over" (given 0 collective input)..?

(I need to have the blades at full cyclic input in 'any one' direction as the rotor comes to a halt..)

Thanks in advance..:ok:

spinwing
7th Sep 2010, 00:02
Mmmm ...

I believe the Hydraulic system on the BK117 and the EC145 (BK117C ??) is basically the same Hydraulic pack as also used on the Bo105 series (with some subtle variation).

It DOES run off the main transmission and thus when the rotors are stopped there is NO hyd. pressure. As well as this the Rotor Brake on these aircraft is not one of their strongest features ... and I really doubt that it would stop the rotors with any kind of power applied to them.

Having said that ... although I have many hours in the 105/117 I have not flown the 145.

maxtork
7th Sep 2010, 00:22
I would bet that you could indeed make full deflection of the cyclic during shut down either with hydraulics or not but doing so while the blades are still spinning is a tougher deal. You would have to make this maneuver contingent upon a very low rotor rpm as you run the risk of a mast moment exceedance otherwise. I haven't played with the cyclic on shut down (I'm not a pilot either) so there may be a windo of time when tip speed is low enough and pump speed is high enough to pull this off. I'm not sure exactly what you are trying to accomplish but if it is simply to move the cyclic to the stop in one direction then it may be just as easy to do so without hydraulics after rotor stop. I wouldn't want to fly it this way but you can sure move the controls full travel with a little effort.

Good Luck

Max

spinwing
7th Sep 2010, 00:38
Mmm ...

I think you will find that a full cyclic movement will be tricky ... as you would have to 'trim' the stick fully over and I vaguely remember that being a 'no no' .... but then my brain is old and its been 7 years since I sat in one of those 'slippery lil suckers' ....

EC145: No fadec but does not take much longer then the EC135 to start once you get handy with it and a feel for the "rigging" of the fuel control. Either aircraft I can get of the ground in less then 4 min, just the 135 a little less effort.

30-35 Celsius and up: The air conditioning in the EC135 is reasonable to bad especially compared to a BK117 or AS350, the EC145 is 10 times (if not 20 times) worse, and I have flown multiple tail nrs for hundreds of hours so I don't find this aircraft specific or type specific. (Metro and AMC completions)

The heater in the EC135 is good! The heater in the EC145 is as bad as the AC and flights over 45 min in the winter will result in loss of feeling in your feet. Good thing the pedals of the EC145 are tied into the autopilot, lol.

Moving the cyclic once on the ground in the EC145 will guaranteed get you in trouble if too enthusiastic in terms of Mast moment limits and a lot of maintenance to be performed, please, don't.

Behavior in turbulence: EC135, a lot of nose pitching up and down, rotor always steady even up to 75 kts of wind over the mountains. (even when I am far from "steady) Fadec does a great job, autopilot will "lose" it sometimes and need some assistance in "getting back". EC145, more of a shaking left and right, rotor all over the place and manual mode recommended for a reason. Autopilot seems to keep up better although I have not had a chance to fly her to the "limits" yet. So far she never kicked off on me.

How I would describe the difference? The EC135 is a BMW 3 series, the EC145 is a VW van. Both nice but different. For police work or even EMS (especially scene's) give me an 135 (2 or 2+) anytime. For Hauling 3 medcrews and an isolette, the 145 is the perfect machine.

Other then that they are both a dream to fly and designed to be single pilot IFR. And they are good at it! I have close to 1500 hrs in the 2 combined and am in love ! Remember, Just like a woman, no such thing as perfection....you just have to get to know her and find what she likes and what she doesn't like and sometimes there is no logic behind it, at least not for a simple mind like myself.


My 2 cents....

Sorry, it was late last night and I missed a couple of questions. Some of them have been answered but this is just my opinion in addition to..

If I am flying it, then land and want to stop the rotor with retained hydraulic capability, this would be doable, right?
--> I use rotor break but keep the engines on "ground idle" or something like that, right?

Hydraulic rotor brake, one pull if you time it right to full blade stop after engines are off and NR below 50 %. Unfortunately you cant leave the brake on to prevent turning of the blades by wind unlike with the EC135

Cyclic movement EC145, full deflection possible and part of pre start checklist with engines off and rotor not turning ( see the mast moment issue written before if you do this with engines running and rotors turning). Unlike the EC135 you can and should. EC135, please dont even try. It wont and if it does move you might just have bend the very thin walled push pull tubes..

Even though I never tried , and never hope to try, apparently the 145 can be flow without hydraulics in the event of a dual failure, the 135 however is a no go.

Take care

apparently as in: Appearing as such but not necessarily so.

Thanks

spinwing
9th Sep 2010, 05:21
Mmmm ...

Well your clue is with the manufacturer .... in their wisdom they have NOT allowed for both Hydraulic systems to be able to be turned off at the same time .... if there is a failure the 2nd system automatically becomes the active system .... what does that tell you? :=

:E




BTW ... during my conversions on to both the Bo105 and the BK117 it was emphasised that the aircraft become uncontrollable with both systems U/S.

I don't think that has changed.

otter712
9th Sep 2010, 13:28
"if there is a failure the 2nd system automatically becomes the active"

I believe they are both active at all times. Both systems run independently and simultaneously to generate the entire pressure for boosting the main rotor controls. If one system fails, the remaining system continues to supply......

It's not a bo105 neither is it a BK117 (just on paper a BK117-C2 for certification purpose)

Also I understand that "in theory" all answers are to be found at the manufacturer. But that isn't the purpose of an discussion at a forum. Here is an opportunity to exchange knowledge that is already in the field.

Please try again

Your welcome

spinwing
10th Sep 2010, 02:37
Mmmm ...

otter712 .... Ok here we go ...please listen very carefully as I will only say this once .....

...... I believe they are both active at all times. ... I believe you are WRONG!

Certainly they may both be pressurised at the same time but only System 1 is actively controlling the aircraft in 'normal operation'.

This from the Bk117 MBB Helicopter Training Centre Pilot course notes ....

For reasons of redundancy the hydraulic unit is constructed as a tandem system i.e. it consists of two separate systems which operate independently of each other. One of the systems (system1) is the MAIN system the other system (system 2) is the STANDBY system. Under normal operating conditions ONLY the MAIN system functions as the (controls) booster. If there is any malfunction within the MAIN system, it will be immediately cutoff and the standby system will be actuated automatically.

As with most duplicated systems on aircraft that are not designed to fly without hydraulic power to the flight controls a hydraulic system failure in flight IS A CRITICAL FAILURE A REQUIRES A LANDING ASAP.

Now this forum not the place to go into the intimate detail of the Hydraulic pack workings should you wish too ... please go back to whoever did your type training or find a knowledgable mechanic to take you through it.

I understand the Hydraulic packs on the EC145 are the same as for the BK117 but the 'pilot' valves instead of being activated by pushrods are controlled by 'teleflex cables' there may be some other subtle electronics interface bits added but I confess to not knowing about those on the EC145.

Cheers ... good luck ... :)

otter712,

I see that you've edited your post, but the assumption you made is still incorrect. spinwing is right (hmmmmm) :ok:

spinwing, the only point to make is that a hydraulic failure (amber 'Hyd 1 - 2') is a "Land as soon as practicable" corrective action, not a "Land as soon as possible" response.

spinwing
10th Sep 2010, 07:12
Mmm ...

Hi John,

Agreed that in the checklist its a 'land as soon as practicable' ... particularly if over water .... having said that ... in a machine which is effectively unflyable without hydraulics would you take the risk ?? (unless absolutely necessary).

A bit like the difference between the 212 and the 412 ... 212s will fly reasonably happily without Hydraulics on ... but the 412 will most definitely not! .... and the company I'm with atm has reflected this in its SOP's ...

BTW .... hows the Beemer?

With a rigid main rotor head, exactly the same as a Bo105 and BK117C1, and flexiball controls, I doubt it very much!!

As Spinwing says, both hyd systems are active (pumps running) but #2 is in bypass (no pressure) until #1 fails.

A Bo105 in the UK did have a temporary (long enough to scare the sh*t out of the pilot) dual hyd system failure, in flight, about 4 - 5 years ago.

I might be wrong, If i am, I apologize for giving you grief, but please, then tell me how to interpret this one ( I tried to insert a picture of the page but can't figure it out, I will type it instead):

Page 04-32, Eurocopter EC145 (BK117-C2) training manual states (word for word):

Redundancy provision:

The hydraulics power system is a dual system. It has two identical pressure supply systems, system 1 and system 2, that operate independently. Under normal operating conditions both pressure supply systems simultaneously generate the entire pressure for boosting the main rotor controls. System 2 in addition boosts the tail rotor controls. If one of the pressure supply systems fails, the remaining system continues to supply the main rotor actuators. This causes the operating force of the mechano-hydraulically operated main rotor actuators to decrease to half.

Now I am not an engineer, just a pilot and my knowledge is from what I read. How am I reading this wrong?

I hear what you say about the BK, quote:

One of the systems (system1) is the MAIN system the other system (system 2) is the STANDBY system. Under normal operating conditions ONLY the MAIN system functions as the (controls) booster. If there is any malfunction within the MAIN system, it will be immediately cutoff and the standby system will be actuated automatically.

But I assure you, and I just read the damned chapter 3 times and this is non existing or no mentioning regarding a MAIN and STANDBY function of any of the systems in the EC145 manual.

I will email you a scanned copy of chapter 4 if you pm me your email address. I don't mind being wrong, it's all part of "learning", but I sure as hell want to know where I am going wrong if so the case... otherwise all this was a waste of energy.

10th Sep 2010, 15:58
Gentleman,

Here we go. Since the outcome so far was not satisfactory to me at all and I didn't feel I walked away from this discussion, wrong or right, having learned something, I took it upon myself to call an old acquaintance of mine under who's command I once had the privilege of working and now is a prominent figure in the Eurocopter division of my area (Americas).

The EC145 hydraulic pack is essentially the same as the EC135 hydraulic pack. Eurocopter quote: for whom this might be unacceptable, verify part numbers BK117 A series through C1 series and note the difference of that of the BK117 C2 (EC145). Therefore, as stated in the EC145 manual and now twice word for word quoted to you for your information, both pressure supply systems simultaneously generate the entire pressure for boosting the main rotor controls. In contrary to the earlier BK series, there is no such thing as an active and standby system.

Mr spinwing, I rest my case. The EC145, which is not a BK117 in the sense of its entire design, although some/a lot of similarities, is something you might want to reeducate yourself on if my answer still is not to your satisfaction. I invite you to call Eurocopter yourself if you feel the need to do so.

At the same time Mr spinwing: Thank you for this discussion, this is the ultimate way for me to increase my knowledge to the point of practical application and understanding. I could not have done so without you. I just hope you yourself learned something as well.

best regards

Otter

spinwing
10th Sep 2010, 23:23
Mmm

Otter .....

Without a doubt I have learned something .... that the Hyd packs though similar DO operate in a different manner ...

As I said in my posts I was only intimately familiar with the Bo105/BK117 set up and was not aware of any differences ... you have proved to me those differences and I can only say that I think that is a good thing ... obviously Eurocopters have improved the operation of those packs by having them now operate simultaneously ... from an engineering and safety point of view that is a product improvement ...

Having said all that we still have an aircraft that cannot be flown with both hydraulic packs disabled :eek:

Keep on with the probing questions .... tenacity can be good ... for everybody :D


Cheers and take care ..... :ok:

I need some specific info on the Front Doors Off limitation.

Looking at the ec145 flight manual supplement F M S 9.1–2, it would seem that one is limited to 30kts with either or both the front (crew) doors removed.

We are looking at using the ec145 for vertical reference sling work (100-200') precision stuff. We previously used the BK117B2/C1, and it works very nicely with the front door removed. Does anybody know of any operators using the ec145 for VR yet?

As flying around doing drill moves at 30 kts is not really an option. According to this thread, there is some sort of device that locks the door into place, about 100mm wide gap between the door and floor. Perhaps someone/an operator has some experience with this.

Any info would be greatly appreciated,

Red Ant

ECL_FTE
23rd Nov 2010, 20:05
yes there is an option for the forward doors that allows you to fly with the door slightly open or with a wider angle open. If you look in the flight manual supplement 9.1-2 operation with door open and look on page 3 you'll see the airspeed limitations. on top of page 4 you have the part number for this "spoiler" option : "Use of EXTENSION pos. is only possible when the door locking device P/N B520M4023051 and/or B520M4022051 is installed"

fully extended your speed is still limited t0 30 KIAS but with the small angle (spoiler position), you can fly up to 100 KIAS.

Hi folks,:O
I have a question for 145 pilots:
At high density, during hover, in the NORM mode operation, I guess the rotor speed is between 101% and 103.5%..is it 102% like the 139 or slighly more?:rolleyes:

ECL_FTE
14th Jan 2011, 17:17
I'm not quite sure of the question but the Nr will be at 103.5% in hover above 6500 ft density altitude. It's at 101% up to 3600 ft density and a constant increase from there to 6500 ft. Hope that answers your question.

princi
17th Jan 2011, 18:31
Thank you very much..:)
Do you know if at 55 kCAS, still at high density, the NR drops down to 100% and how it decreases to 96.5% increasing the speed?

ECL_FTE
17th Jan 2011, 19:21
The NR is controlled by the VARTOM and the control law is as follow:

For IAS<55KIAS, Nr= 101% up to 3600ft DA. Then it will increase up to 103.5% above 6500ft DA.

For IAS>55KIAS, Nr= 96.5% up to 3600ft DA. Then it will increase up to 101% above 8800ft DA.

For a given altitude, the Nr will slightly increase with airspeed. For example at Vh, Nr will go up to ~97% up to 3600ft DA and up to 102% above 8800ft DA.

So to answer your question, if you're at high DA (let say above 8800ft), the Nr will be at 103.5% in hover and up to 55KIAS, passing 55KIAS it will drop to 101%

princi
19th Jan 2011, 14:15
thnks! really precise..
I thought that increasing the speed, at a fixed altitude, the NR would decrease in order to reduce as much as possible transonic effects on the advancing blade..:bored:

The odd thing is the local hype says 'an upgrade and a new type' and yet the suggestion is that what we are about to see are two upgrades, one to the AS350B3 and the other to the EC145/BK117C2. The latter is expected to be EC146/BK117C3 offering a number of [I]must have [I]features including FADEC and the fenestron. Certainly an airframe offering features the industry has wanted for a while.

If the 146 is indeed the 'new type' then it suggests that EC have caught the overhype bug that turned the magnificent Bell Magellan into 'just' a Bell 412upgrade.

If not........ then there may be a wow wow factor after all.

Interesting -

All the tufts on the fenestron and the variation between the 2 photos of the size of the endplates on the horizontal indicate that there may be a few "issues".

Maybe they will work out that this is not the best place to put vertical and horizontal surfaces in relation to the fenestron. The 135 has it's little quirks there and look at the evolution.

To me - "The Duke" RAH-66 configuration makes sense - T tail.

To ECD - it probably is because "thats where we always put them."

Like "Topsy" from Uncle Toms Cabin - "I wasn't borned, I just growed!"

FADEC would imply Arriel 2 - goodbye range - bad SFC.

But hey if this was paid for by REGA who have extremely deep pockets - 109K2, 109SP and now this puppy, it won't matter because on a good day you can see from one end of Switzerland to the other end and to get there you will have to pass about 10 rescue helicopters and their fuel facilities! Whats the bet the next time you see this machine is Samedan in CH doing high altitude testing?

6th Mar 2011, 11:55
As I understand it, it's the gearbox that is the limiting factor, ie. it can't take more power from the engines. As the test aircraft looks to be using the same rotor head and blades with the pendulum weights I would suggest it's the same gear box and therefore possibly a BK117 C3 as opposed to an EC145/6 T2 etc.

I hope I'm wrong as it's high time the EC145 was a reality and not just a commercial name.

It can't be a 146 - you obviously aren't familiar with EC's numbering logic....;)

Saw the Tango 2 at Heli Expo, sleek looking but nothing to take home about. I guess they learned that the 145 in itself was more up to parapublic missions with the wider cabin space than the 135 and done another hybrid.

I could never understand how those oversized vertical tail stabilizers did not snap tails off on the earlier 117's and the ec145. The size on the ec146 looks a lot safer from that respect at speed. In fact I heard a rumour that a 117 stateside did loose its tail some years back for that reason.?

Picture taken from the Japanese Earthquake forum ....
I've just noticed the Main Rotor Blade tips are tapered off at the end, whereas the old BK117 blades are squared off at the end. Does anyone know the reason for this?? Is there still Static Wicks fitted??
I thought all the blades were meant to be interchangeable and the same between the B & C models...

curious, KP

PS - great news for the fenestrom and upgraded gearboxes on the Ec145 T2 !!

Bolkow .... if by the above you mean the NewYork 'Colgate' machine you need to research that incident ...you will find it had nothing to do with the vertical stabilisers and a lot to do with an improper repair to taliboom vertical spar cracks.

Hi Sinwing,

the vertical stabliziers on the BK117 have an soft area, a predertimined breaking area, which will break, if you mishandle the bird so far, that the blades will reach the stabilisers.
Had happend before - have seen the repair afterwards and you can tick the area with a coin, if you want to know, where it is.
If you handle the bird according to the handbook, it won´t happen...

Greetings Flying Bull

Cutted the fin one time personally at the controls, have seen a second time live and in colour and have heard about a few dozen times about it by ECD.

Thats the reason why the BK have still such an soft area on the right fin.

It's not a question of the RFM, simple a question of wind direction, speed and turbulence and be sure ECD knows everything about. In the RFM you will not find a single hint about it.

In my personally file the wind came with just 20kt gusts right about a 15m away airfield hangar in my 8 o'clock position causing intensive blade flapping during starting up the first engine.

When I was in Donauworth for sim training, the instructor said the 5 bladed rotor is not going anywhere near the new 145 because it took more power without any real benifit in lift. But it was a smooth ride.

The newest member of Eurocopter’s helicopter family was formally launched this month with the unveiling of its EC145 T2 – an evolved version of the popular twin-engine EC145 that incorporates new Arriel 2E engines, along with the company’s Fenestron shrouded tail rotor, upgraded main and tail rotor gear boxes, an innovative new digital avionics suite and a 4-axis autopilot.
http://pilotmagazin.ro/wp-content/uploads/2011/03/EC145T2_3.jpg EC145 T2 debut was at the Heli-Expo 2011 exposition in Orlando, Florida, where Eurocopter also announced launch agreements for a total of 17 helicopters from four international customers, who plan to utilize these rotary-wing aircraft in emergency medical services (EMS), oil and gas operations and business aviation.

No, this is definitely not about lipstick....

It adresses the points which hinder a bigger success of the EC145 in the EMS market compared to the EC-135:
- Insufficent Power
- Open Tail rotor (which is considered almost a no-go for HEMS in many countries in Europe).
- No FADEC

Reasonable move on behalf of EC.

This ship is not primarily aimed at bragging rights at your Golf Club....

18th Mar 2011, 22:19
The -C2 cried out for FADEC so thats a good thing.
Replacing the T/R removes the issues with the inclined G/box meshing and Tail shakes/repairs.

All seems good...so far...I dont know what fenestron issues the 135 had/has.

"..the instructor said the 5 bladed rotor is not going anywhere near the new 145 because it took more power without any real benifit in lift."
With all due respect to your Sim-instructor, that IS a load of bullcrap..
If the 5-bladed rotor has any problem, it is 'being shot down for political reasons'..
But that rotor won't die, it will just reincarnate in a stronger, more viable form:ok::}

Was it only last week? Time flies!

Someone, not sure who needs to be congratulated on the quality of work on the EC145T2 mock up I was asked where the serial number was! Not so sure 'works of art' in this sphere have started carrying a s/n just yet..... although '1 of a series of 3' might just catch on and who knows they may get something akin to a BAPC number one day!

BTW the glass cockpit is the same as that from the EC175 [and that part looked 'real' enough as well] - I believe it will not be an option, take it or pay heavily for something else. That option will have an effect on law enforcement use and the TFO/observer will probably have to use the same screen.

I might be wrong, but I have a feeling that EC145 mockup is the same one that was displayed at the Heli Expo 2002 and the ILA in 2004 (see here (http://myaviation.net/?pid=00130187)), but with T2 modifications/alterations added this time around ;).

You may get more of a response if you made your question in plain English rather than in shorthand and links to documents, expecting Rotorheads to work out just what you are after.

I cannot fathom out your request, and suspect that the lack of response is because others cannot either :confused:

Max Torque and RPM are different, with same engines. I'm just wondering why.

Senior Pilot
15th Feb 2012, 05:19
Maybe the EASA document is current (November 2010) whereas the FAA one is 3 years older (November 2007)? They also refer to different Construction Number blocks, but that could be region specific or give a clue to an update in the EASA Type Certificate that is missing in the FAA one.

Rotorheads are pretty good at many things, but mind reading isn't high on the list ;)

Are you comparing the EC145 (with EASA TCDS) with the UH-72A?
The two h/c are not the same, the EC145 is the civil version and the UH-72 is the US ARMY version.

ECL_FTE
15th Feb 2012, 12:38
The EC145-C2 and the UH-72A are the same aircraft
Prior to delivery to the Army the aircraft is certificated as an EC145-C2. Therefore the flight manual limits are the same for both aircraft.
As already said the TOP power has been increased from 83% to 88% AEO long time ago.

The United States Army wanted an off-the-shelf civilian helicopter with no modifications, military radio installation noted, but the whole idea was to minimize the cost with no R&D associated exspenses. I do however believe the United States Army, had Eurocopter change the direction the rotors turn to (counter-clockwise) to bring the airframe inline with all the other single rotor ships in the inventory. Just my 2 cents, paid in full!!!

The EC 145 is german origin, not french!
So the rotors are turning anticlockwise ( like the BO105 ) ...

BK117...Bo105?

B = Bolkow (AKA Bo)
K = Kawasaki

Kawasaki builds the basic Airframe/Cabin - and ships them to Donauwoerth for assembly by Bolkow (even the US Army ones)

The assembly "Lines" for the US frames were interspersed with civil frames, I was there when they went through, but I believe the US frames had a block of numbers allocated to just that contract. The only real difference on delivery was the external finish. Secure Radios & any special role equipment fitted in the states I think?

Eurocopter’s EC145 Helicopter: 500 Deliveries and Still Going Strong

http://www.defpro.com/data/gfx/news/de79ef87d307e2dfcc01c0b680dfc3f80b2a5110_big.jpg

The 500th EC145 helicopter was delivered by Eurocopter today, marking a new milestone for this twin-engine workhorse rotorcraft that continues in high-rate production for international customers.

Eurocopter’s 500th EC145, along with the 501st production helicopter, were provided to Transportes Aereos Pegaso, which is the largest Mexican operator in the Gulf of Mexico. Pegaso already operates 13 EC145s and four of the predecessor BK117 versions, with an additional EC145 to be provided to this customer in May.

Delivery of the 500th EC145 occurred at Eurocopter’s Donauwörth, Germany facility, where the helicopter is built. The handover comes 10 years after Eurocopter’s delivery of the no. 1 EC145 in April 2002, and it was witnessed by Francisco Nicolas Gonzalez Diaz, the Ambassador of Mexico in Germany, along with political and industrial representatives and some 600 company employees who have contributed to the helicopter’s successful production run.

Can anybody tell me what the approximate hourly operating cost is for the 145?

chopper2004
14th Feb 2016, 01:55
Trying to work this one out , with the original EC145, production has now ceased leaving the H145 (T2) and new EC145e being the new kids on the block -

Will the price of a H145 come down so that parapublic operators and offshore who have had an interest / do fly the EC145 can afford the H145?


Or

Will they go for the EC145e variant....for cost effectiveness but as the a/c has pretty much had its SPIFR stripped including co-pilot controls to save weight - I suspect within Europe, the 'e' may not be popular with EASA w.r.t public service but popular in North American marketplace


In short looking globally at the EC145 customer marketplace compared to the current H145 -

Off the top of my head, current customers

Babcock-Bond (Anglian Air Ambulance and Scottish Ambulance Service) here in UK
DRF and ADAC in Germany
Pacific Helicopters in Papua New Guinea
Dare County Healthcare , N,C, USA
INAER Italy
Baden-Wuttenberg Polizei
Svensk Luftambulans.Sweden
Corporate customer in NZ and Turkey recently

Yorkshire Air Ambulance should be online this year

Pegaso in Mexico are buying ten airframes

On the mil and parapublic side to come

Elbit Systems has procured H145 for Israeli police,
Royal Thai Navy and Army should be getting theirs come next year

Its pretty much a decade since the BK117-C2 went into production and now ceased....

Also with Airbus increasing the MTOW , that may increase the cost per airframe?
