NASA Airbus Helicopters H135

[Kulwin Park]

Thank you Chopper2004. I see that "442" doesn't have the radome fitted on it's nose, nor does it have the extra oil cooling vent on the left side transmission cowling. It must be modded differently, or about to get mods applied to it.

When IBFs are installed, then the oil cooling vent is located at the end of the doghouse. Therefore, no oilcooler outlet on the transmissioncowling.

Skadi,

All new T/P3 135 now use the upper vent method regardless of if IBF are fitted or not.

Ok, the engine air intake also from the side with just mesh cover? The reason for relocating the vent was to prevent ingestion of warm air into the engine.

Yes for both P and T models.

P3H models come with IBF as standard, T3H it is an option.

The 300+ hour installation time of the IBF on the P/T2 sort of forced them to incorporate the design into the P/T3.

Can you give me the FLM reference for this limitation?

Thanks

For the T3 CPDS model with the SPIFR/DPIFR kit:

FLM 9.2-56 pg5 para 2.2

hope this helps.

Thanks. That makes sense, since the PW engines were very sensible when operating in offairport szenarios. Lot of wear at compressor blades without IBF

What is the MTOW on the 135?

Typically 2980kg

Thank you Skadi & Havick. I had not thought of the hot outlet air going straight to the engines.

That's been increased on H models to 3100kg.

Unfortunately the T3 comes with a limit for downwind (25 kts) that isn't there on the earlier models. Again, all for the direct air intakes and reingestion of fumes.

Honestly I’ve been pretty surprised at the lack of support on even the dumbest of parts and other issues from Airbus with our T3.

eg. dzus fasteners for the tail rotor driveshaft cowl are no longer procurable, yes you can source direct through other suppliers but really?

Some major avionics parts no longer supported or procurable on what is only a 5 year old machine.

It’s a great product but death by a 1000 cuts to push you into something else for the next purchase which is kind of sad.

sorry for the thread drift. The nasa machines look great all lined up.
