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]
A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.
The starter is usually an air turbine type, similar to the cartridge starter, but uses the APU's bleed air instead of the burning gases of the propellant cartridge. Most cart starters can also use APU air to turn them. When the rotating speed of the engine is sufficient to pull in enough air to support combustion, fuel is introduced and ignited.
An aircraft fuel system allows the crew to pump, manage, and deliver aviation fuel to the propulsion system and auxiliary power unit (APU) of an aircraft. Fuel systems differ greatly due to different performance of the aircraft in which they are installed.
