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]
In 1997, Ingersoll Rand acquired Thermo King from Westinghouse for $2.56 billion in cash, 13 times earnings, [9] and added it to its Climate Control Technologies (later Climate Solutions) businesses, alongside Trane and Hussmann. At the time Thermo King controlled close to half the global market for refrigeration equipment. [9]
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 typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
