The first German jet engines built during the Second World War used a mechanical APU starting system designed by the German engineer Norbert Riedel.It consisted of a 10 horsepower (7.5 kW) two-stroke flat engine, which for the Junkers Jumo 004 design was hidden in the engine nose cone, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
A Honeywell GTCP36-150(CX) auxiliary power unit mounted in the tail of a Cessna Model 750 Citation X. Honeywell auxiliary power units are a series of gas turbine auxiliary power units (APU) made by Honeywell Aerospace. Honeywell started manufacturing APUs in the early 1950s and since then they can be found on many aircraft. [1]
Auxiliary power is electric power that is provided by an alternate source and that serves as backup for the primary power source at the station main bus or prescribed sub-bus. An offline unit provides electrical isolation between the primary power source and the critical technical load whereas an online unit does not.
Auxiliary power units (APUs) are backup systems that deliver power to the engines, flight control and other avionics on an aircraft in the event the main power systems fail. [ 50 ] The Honeywell 131-9 APU was used in an emergency landing when U.S. Airways Flight 1549 splash landed in New York City ’s Hudson River on January 15, 2009, called ...

Around 300,000 refrigerator trucks with auxiliary power units are on the road in the United States, according to a 2013 estimate. [3] In recent years, truck and fuel cell manufacturers have teamed up to create, test and demonstrate a fuel cell APU that eliminates nearly all emissions [4] and uses diesel fuel more efficiently.
The Turbomeca Artouste is an early French turboshaft engine, first run in 1947. Originally conceived as an auxiliary power unit (APU), it was soon adapted to aircraft propulsion, and found a niche as a powerplant for turboshaft-driven helicopters in the 1950s.
