Thermo King is an American manufacturer of transport temperature control systems for refrigerator trucks and trailers, refrigerated containers and refrigerated railway cars along with heating, ventilation and air conditioning systems for bus and passenger rail applications.
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.
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 1996, the Thermo King Model 'C' refrigeration unit, the world's first front-mount refrigeration unit for mobile trucks, was designated an International Mechanical Engineering Landmark by the American Society of Mechanical Engineers. Jones designed and built the prototype from junkyard salvage.
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.
An interesting feature of all three German jet engine designs that saw production of any kind before May 1945: the German BMW 003, Junkers Jumo 004 and Heinkel HeS 011 axial-flow turbojet engine designs was the starter system, which consisted of a Riedel 10 hp (7.5 kW) flat twin two-stroke air-cooled engine hidden in the intake, and essentially ...
The base model which is used to supply compressed air to air-start systems. It can also be used as cabin heating if necessary. [1] AI-9V A variant of the base model that is used to supply compressed air to air-start systems and air conditioning. It also supplies electricity to on-board electrical systems with a 3 kW generator. [2] AI9-3B
It is normally a small gas turbine. Thus, one could say that using such an APU is using a small gas turbine to start a larger one. Low pressure (40–70 psi or 280–480 kPa), high volume air from the compressor section of the APU is bled off through a system of pipes to the engines where it is directed into the starting system.
