Auxiliary Power Unit Aircraft

This certification guarantees to manufacturers and operators that the.

Auxiliary power unit aircraft.

Starting power for the main engines. Pneumatic power for cabin air conditioning systems. With more than 95 000 apus produced and more than 36 000 in service today honeywell has a large apu installed base and is poised for further growth. Unlike the aircraft s main engines the apu outputs almost no thrust.

Shaft power for other pneumatic and hydraulic systems. An auxiliary power unit or apu allows an aircraft to operate autonomously without reliance on ground support equipment such as a ground power unit an external air conditioning unit or a high pressure air start cart. The auxilary power unit safir 5k g z8 can be used in civil aviation applications all around the world. Aircraft apus generally produce 115 v alternating current ac at 400 hz rather than 50 60 hz in mains supply to run the electrical systems of the aircraft.

The auxiliary power unit apu is a small gas turbine engine mounted in the tail cone of an aircraft to provide autonomous electrical and mechanical power for the following. The auxiliary power unit is an actual turbine engine more appropriately called a turboshaft engine. Most of the power produced is used to run an electric generator and provide pneumatic air pressure.
