Web16 mar 2008 · The APU is a gas turbine generator whose basic function is to provide power on the ground when it is not available from the terminal, and to provide air for air conditioning and engine start. It can also be used in the air in case of the in-flight failure of one or more engine-driven generators. An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. AP…
