Auxiliary Power Unit Aircraft Function

The technology used in the mt is derived from diesel engine turbochargers aircraft auxiliary power systems and automotive designs mts consist of a compressor combustor turbine and generator as shown in fig.

Auxiliary power unit aircraft function.

Others can produce 28 v. Apu is necessary to start up the main engines it also powers the airplane s electronics. Auxiliary power units are usually found on large aircraft and naval ships as well as some large land vehicles. In airliners apu s are usually located at the very rear of the aircraft below the tail.

Applications include powering environmental systems for pre cooling or preheating the cabin and providing power for crew functions such as preflight cabin cleanup and galley kitchen operation. An mt is a mechanism that uses the flow of a gas to convert thermal energy into mechanical energy. Pneumatic power for cabin air conditioning systems.

Starting power for the main engines. 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. 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. How an auxiliary power unit works.

Knowing this will be an explanation of auxiliary power units apu and how they are involved in the operation of an aircraft. 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. 2 3 6 the combustible usually gas is mixed in the combustion chamber with air.

An auxiliary power unit also known as apu is a device on a vehicle that provides energy for functions other than propulsion. Design of auxiliary power unit apu for co operation with turboshaft engine p 9 the section that comes below presents types of aircraft engines.
