EC135T2+ or P2+ or T3 FM extracts on performance and limitations?
Greetings
Like to run the performance numbers on capabilities of the newer models to operate in a continual ISA+20 environment from SL up to 8000' PA. Max payload, range, endurance, IGE/OGE hover.... Appreciate if some interested folks can pm me and send soft copy of Flight manual extracts. I have an excel template that can send out to be filled in also. Checking to see feasibility to getting one working here. |
AHD added a fifth blade together with some major design changes on the tailboom:

Maybe the new fenestron, main rotor and blades of the X4 project ?

I didn't know about the X9 program but the EC135 s/n 001 seems to have been the testbed of a lot of things from Eurocopter so...
|
Heres a listing of the different programms of AH:

After 2 shocks today, have they finally got rid of the collective / metal watch strap phenomenon?
|
Sweaty hands eh?... Keep your hand on the collective twist grips and you want get zapped. I think is designed to switch the transponder to GND and VEMD flight time recording, although not sure on the later.

Sweaty hands eh?... Keep your hand on the collective twist grips and you want get zapped. Apart from missing the bit of my post that says "collective / metal watch strap", its a bit hard operating the radio selection box, which is when the shock occurs, without taking a hand off the twist grips! ;) |
Why you get a shock?
A relay is an electro-mechanical switch that opens and closes under the control of another electric circuit. When current flows through the coil of the relay, a magetic field is created that causes an armature to move, either making or breaking an electrical connection. When current is removed from the relay coil, the armature returns to its rest position. It is important to place a diode across the coil of the relay because a spike of voltage is generated when the current is removed from the coil due to the collapse of the magnetic field. As the field within the relay collapses (through your arm) you get a taste of the spike. Ouch! I have personal experience and it definitely bites. 32-60-03 Ground Relay PP20E -> CB 1CX GROUND REL -> Relay 2CX -> 8VE COLLECTIVE PIL It controls various things through TB27 A,T,J and V respectively. Maybe 2p worth of diode may fix it! Needles to say that the radios may endure the spike as well? |

Thanks RVDT, although I think it has been covered previously in this thread. I was just asking if the new design might have a different grounding system, removing the chance of this little shock.
Mind you sometimes it comes in handy after going round and round and round and round and round and round and round and round and :ooh: |
Airbus Modifies EC135 as Environmental Tech Testbed
A German photographer spotted a modified EC135 at Airbus Helicopters’ development facility in Donauwörth, Germany. Most striking is the light twin’s new horizontal empennage, moved to the top of the vertical fin. The bottom of the vertical empennage also has a different design and the tailboom now appears to have a circular cross-section. In addition, the helicopter sports five main rotor blades–instead of four on the stock EC135–with swept tips. The landing skids also have been redesigned. Asked whether the helicopter is the prototype of a new EC135 variant, Airbus Helicopters answered that it is “testing environmentally friendly technologies on a demonstrator aircraft.” While the EC135 is being used as a testbed, Airbus said the technologies should be seen as “transversal,” meaning not specifically intended for any one particular helicopter model. Meanwhile, the manufacturer is gearing up for the first delivery of the latest EC135 version, the EC135 T3/P3, which was previously delayed to the fourth quarter. Announced at Heli-Expo 2013, the new model offers several improvements over the current EC135 T2i/P2i, yielding a 66-pound mtow increase and improved hot/high performance. http://www.helionline.net/517-967277...ture/41688.jpg |
I'm guessing some X4 linked technologies...
|
Can anyone shed any light on a co-pilot reversible seat for the 135?
I see it listed in the IPC, Chapter 25, as 'against FD' (Flight direction I am guessing) and the picture showing it facing backwards, but I have had no luck finding any other ref to it? TCF |
Yes, usually it's a part of HEMS (single-pilot) configuration, or in hoist operation configurations (HHO)...with hoist on left side.

Is it just me, or does that machine appear to have 5 MRBs ?

Category A - external equipment
The Category A performance, Mass limitations - specified for:
Clear heliport - external equipment is a factor VTOL(1-3) - external equipment is NOT a factor Logical, when it comes to Cruise flight OEI, external equipment is a factor at Vy (65 kts) - actually in the exact same way as with Clear heliport. I'm having problems with understanding how Clear heliport Cat A ops. are effected by external equipment when TDP/LDP's are up to 40 kts (with the same deductions as at 65kts) and VTOL ops. are not effected by external equipment even when FLIR and the SX-16 are in the downwash - vertical drag region. Any ideas? |
Anybody got the position of RH/LH installed hoist system? I could only find the mass of installed system (approx. 54 kg) but nothing on the position of the system and the lateral and longitudinal position for hoist load.
The supplement manual holds no required information, only a chart showing when you are ok and when not... not very accurate. |
Phoinix,
I have in front of me; FMS 9.2-20 "Supplement For External Hoist System LH/RH Side" ... pages 1-24. Is this the same info you already have? Para 6.1 of Supplement; Mass and Balance Correction says " Refer to Equipment List entries in Section 6 of the basic Flight Manual. From Sect 6 of FLM; 6.2.2 "An Equipment List form EL-1 is appended to this section and contains optional equipment of the particular helicopter when delivered. Each item on the list is provided with a number and description for identification, together with its mass, arm and moment." Hope that's of some help :confused: |
Yes... but the hoist was not installed at delivery and there is no entry. ECD normally had SB's with details what to enter into the Equipment list, but I found none.
Do you happen to have a filled out EL for hoist? Also the Supplement said nothing about the station for hoist cable (M&B calculations for hoist ops.) The Fig. 3 doesn't cut it for me :) |
Sorry Phoinix, we don't have a hoist fitted, perhaps someone at Bond or possibly over on the continent will be able to help you on this one.
I take it you just want to know the mass, arm and moment of the hoist unit when fitted? |
Hi Phoinix,
I can have a look at ours, they used to have winches fitted but I can't promise anything. Otherwise ask Rotordomteur (I think that's his handle) he flies to the wind turbines, he should know. Also one of his aircraft works out of Humberside doing the same thing fi you want to ring them. The company is called Uni-Fly. |
Thanks guys. I appreciate your help! If you have the chance, please check your FLM, otherwise I'll contact Rotordomteur.
:ok: |
Had a look in the EL today but no mention of it, I assume they took it all out since we are not using it.
|
Thank you for looking. I just came to ECD, I'll ask them. If they don't know.... :)

Hi Phoenix,
check supplement 9.2-117. Actually, there is nothing in RFM about that. Hoist is directly mounted on the transmission (correction: on transmission mount), no influence. You only have to add this 54 kg to the Gross Mass. After that, there is a chart in supp. 9.2-117 which tells you how much kg you can take on the hoist. It varies from 226 kg down to 150 kg (or 120 kg I'm not sure). So, it's not about the station and longitudinal CG (no influence), it's only about the Maximum Gross Weight and about the mass which you can take on hoist - lateral CG (that is what you must calculate for the conditions). JR |
Hi Jet Ranger
Hoist is directly mounted on the transmission, so station should be zero (0), no influence. Cheers TeeS |
Jet Ranger,
The C of G datum on the 135 - in common with most ABH products is 2.16 metres in front of the leveling point, (approx where the cyclic is). In other words, out in front of the aircraft - consequently, all data points for things fitted are "minus". |
Sorry if I expressed myself incorrectly...wanted to say...hoist is in line with rotor mast, so no influence on longitudinal CG (you can't find any data about the station in RFM or particular SUPPLEMENT)
JR |
Hi again Jet Ranger
http://www.airbushelicopters.com/w1/...otor76_26a.jpg The mounting point is not where the mass acts on C of G, it is the centre of mass of the winch (and any load on the winch) that is important. Cheers TeeS |
Hi TeeS,
on this pictures we see winch in stowed position, but when is in extended position the mass on winch acts in CG. I would appreciate if you have any data about it´s station. JR |
I'll see what I can find out JR, I'm not directly involved in hoisting operations with the 135 but we do have people who are.
Cheers TeeS |
In the meantime, a vid of the winch in action;
:ok: |
