Can anyone comment on the durability of the composite fenestron blades or tailboom cracking in the T2?

Airbus evaluates a five blade MR on H145? :eek:

Have a look on D-HADW behind the ADAC ship:

I think they flew a 5-blade head on a "Quiet" EC135 a while back also.


Maybe they are doing a rotor upgrade along the same lines as the 500C-to-500D upgrade and hoping for the associated improved performance the extra blade can bring.


Will a NOTAR upgrade follow later?:ok:

Comes 11 years after the five-bladed Advanced Technology Rotor was first tested on an EC145:

"Collision" with a sheep was it? Was he Welsh or a Kiwi?

I bet the cyclist was on the right side of the road!

H145 t2
 
hello, can i ask any operators in h145 t2 TOP and landing performance, 8pax, full tank, corporate transport type in tropical country....thanks just new here.

Flying Bull 28th May 2018 08:53

@Lucing - not operating in a tropical country, still, the first twin helicopter I fly designed with power to spare.
In situations, where the BK117B2/C1 needed take off power or wasnˋt even capable of hovering out of ground effect the H145 T2 mostly operates below the blue line, which means within OEI 30 sec range.
cruise 2x74%, OEI 150% 30 sec, 143% 2 min!!!!
The only drawbacks - comfort, itīs vibrating and you have to be vigilant to reduce from T/O Power to cruise passing Vy cause the bird is accelerating quickly - and past Vy +20 you ˋ re back to 2x74 MCP limit from 2x95% T/O Power (104,5 transient)

Lucing 28th May 2018 16:56

Thanks Bull for the info
 
So over all its a fine bird to be operated in corporate / vip transport??... and one more thing how fast can you go in cruising speed with all the loads that i mentioned?thank

....what? NO Active Vibration Control??

With LAVCS on PAX setting - still more vibrations.
You get used to it - but feel the difference, when jumping in occasionaly on to one of the old birds ;-)

@Lucing: "So over all its a fine bird to be operated in corporate / vip transport??... and one more thing how fast can you go in cruising speed with all the loads that i mentioned?thank"
Really lots of gadgets, which make pilot life easy. With the rigid rotor head much space above the heads for people going to/from the bird.
Speed - I usually fly with external add ons (camera, High Intensity search light) and cruise then is about 125 KIAS
Without close to 130 KIAS, it isnīt as fast as the EC155.

It certainly isn't short of power. But it has an unique vibe to it. very hard to explain in words. If you can, get someone to give you a ride.

eivissa 30th May 2018 09:16

In my opinion and after about 400h in it I would not recommend the H145 for VIP. The LAVCS, which was supposed to be an optional equipment, didnt become standard equipment because Airbus is being generous!
The LAVCS is making the vibration bearable, but its still quite a bad vibration level. Anyone who has flown the H155 will think its broken and anyone coming from an H135 will think someone messed up the tracking really bad.
The other thing is, that the vibration are also creating a deep drone that is very annoying on long flights without active noise cancellation (which we dont use / have in our helmets).
The LAVCS motors have actually ripped themselves out of their mounts in the past, which tells a story on its own.

We end up in an aircraft that has electric motors countervibrating a bad vibration from the main rotor and helmets counterscreaming at us to compensate for drone from the structure...nothing gets to the root of the problem, which would be a redesigned (five-blade) rotor and also a dampened (ARIS?) mount of the MGB to the cell. The Five-Blade-Rotor might do the the trick alone (and it actually does according to some Airbus insiders), but the old BK117 way to attach the MGB is no smart solution either IMO.

Hello to all

One quick question is there a different RFM to the EC145 and one for the H145? Or they have the same RFM only with some extra supplements for the differences between the model.

Thanks

FloaterNorthWest 30th May 2018 17:46

The EC145 is the BK117 C2 and H145 is the BK117 D2. They have separate FLM.

Red Ant 9th Dec 2018 09:56

Anybody have pictures of the dual cargo hook beam assembly on the EC145, and perhaps one for sale? please pm me.

wazz'n'zoom 10th Dec 2018 11:07

Does Total have any EC145C2 (BK117C2) globally on contract
 
Long shot for the RW community.
Does anyone know if Total has on contract, anywhere in the world, the EC145C2?

dude12345 11th Dec 2018 17:11

I believe Hevilift PNG have just started operating a ec145c2 for Total.

Evil Twin 15th Dec 2018 07:55

Would anyone have a W&B spreadsheet or similar for the 145 T2?

Cheers
