Hi,
I was just wondering which aircraft have the emergency propeller which comes out when engines cut out and it works like a generator, hydraulics, etc ???
I know of a few but can anyone list all of them and tell me if there is any reference on it? Thanks Big grin

I know for sure the 777 does, but does anyone know if Airbus aircraft incorporate the design into their transports?

I remember seeing one on AA's DC-10 at LAX Superbay hanger, in for routine maintenance. If the DC-10 had it, I'm reasonably sure the MD-11 has them too. Regards.

I believe that all commercial jets have this ability, if they depend on hydraulic boost for control movements. While an APU could also do the job, the APUs on most aircraft cannot be operated above a certain speed and altitude, due to the location of the intake and exhaust ports. I expect that (unless the APU worked off of the same damaged fuel feed) the APU would have been operating during the last few minutes of the Air Transat's flight, and would have been providing power for the controls and other systems.

I know the CL604 has it (I've used it in the simulator!), and so I would presume the rest of the CRJ family must have it.


Next flight.... who knows.

RAT ( Ram Air Turbine) on the A340 as well coupled to a hydraulic pump allows the "green" circuit to function.

The RAT helped save the Air Transat Airbus that skidded into the Azores. There was so little eletrical power that the cabin public address system didn't work and the cabin crew chief had to shout out ditching orders.

Of the a/c I have worked the following had them:-
DC10, 757, A300, A310, A320/1, A340 & the VC10.

Below is the installation on the VC10.



On the picture below of the prototype VC10, the RAT can be seen on the bottom of the fuselage, forward of the landing gear
