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.
The company's first major product was an oil cooler for military aircraft. Garrett designed and produced oil coolers for the Douglas DB-7. [9] Boeing's B-17 bombers, credited with substantially tipping the air war in America's and Great Britain's favor over Europe and the Pacific, were outfitted with Garrett intercoolers, as was the B-25.

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] Over the years Honeywell have produced more than 95,000 APUs and more than 36,000 are still in service. [2]
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.
It was initially developed by Garrett AiResearch, for use as an APU for McDonnell Douglas DC-10. [1] Garrett was merged into AlliedSignal in 1985, then into Honeywell in 1999. Honeywell still provide support for the TSCP700's in circulation. Besides the DC-10, it is also used as APU on the MD-11 and Airbus A300/A310. [2]
Driving position. Its light weight allows the use of a relatively small engine to power the vehicle, a 6V53 Detroit two-stroke six cylinder diesel, with an Allison TX-100-1 three-speed automatic transmission, and allows the vehicle to carry a large payload cross-country and to be transported by fixed- and rotary-wing aircraft.
The C-2A(R)'s lifespan was 10,000 hours, or 15,000 carrier landings; plans require the C-2A to perform its mission supporting battle group operational readiness through 2015. The lower landing limit was approaching for most airframes, and the SLEP will increase their projected life to 15,000 hours or 36,000 landings.
AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors and normal CPUs. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core.
