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 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 ...
The range-extender option of the BMW i3 was designed to meet the CARB regulation for an auxiliary power unit (APU) called REx. According to rules CARB adopted in March 2012, the 2014 BMW i3 with a REx unit fitted will be the first car to qualify as a range-extended battery-electric vehicle or "BEVx."
The Solar T62 Titan is an American gas turbine engine used mainly as a aircraft auxiliary power unit (APU), conventional power generator, turboprop engine for fixed-wing aircraft or turboshaft engine for helicopters.
Maximum power output: 75 kW (100 shp) at 37,000 rpm or 60 kW DC from TCP-24 electric generator at 9,250 rpm gearbox output Overall pressure ratio : 3.15:1 Air mass flow: 1.75 kg/s (231 lb/min) at 37,000 rpm
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.
