Emergency supply device for use in aeroplane, has back pressure turbine that is surrounded concentrically by jacket which forms flow channel and energy transducer is coupled directly to back pressure turbine

摘要

Emergency supply device (1) has back pressure turbine (2) propelled by air flow (14) and an energy transducer (4) which partially maintains the function of a hydraulic system or an electrical system on boarding an airplane in an emergency situation. The back pressure turbine is surrounded concentrically by a jacket (5) which forms a flow channel (6) and the energy transducer is coupled directly to back pressure turbine by a drive shaft (3).The air flow of the back pressure turbine is supplied by an air inlet (9).
