Air impingement starting was not used for US military aircraft after the F-4B, A-5A [6] and F-5 as the pneumatic energy requirement was several times greater than when using an air turbine starter. The gas turbine compressor required to start a J79 with impingement starting was sufficient to start two J79 engines simultaneously in a B-58 when ...
An air start unit (ASU, also known as a "start cart") is a device used to start an aircraft's engines when it is not equipped with an on-board APU or the APU is not operational. [5] There are three primary types of these devices that exist currently: a stored air cart, a gas turbine based unit, and a diesel engine driven screw compressor unit.
Cutaway view of an air-start motor of a General Electric J79 turbojet. With air-start systems, gas turbine engine compressor spools are rotated by the action of a large volume of compressed air acting directly on the compressor blades or driving the engine through a small, geared turbine motor. These motors can weigh up to 75% less than an ...
A Palouste air starter pod is in front. Several British naval aircraft were adapted to carry a Palouste in a wing-mounted air starter pod installation to facilitate engine starting when away from base. [3] A novel use of a surplus Palouste engine was its installation in a custom-built motorcycle known as the Boost Palouste.
A NACA Hucks starter set up to start a Vought VE-7 A Hucks starter connected to start the engine of a Hawker Nimrod A Ford Model T-based Hucks starter owned by the Shuttleworth Collection. A Hucks starter is an auxiliary power unit, almost always a lorry or truck, that provides initial power to start up piston aircraft engines.
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 intake diverter, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
Air tanks can also be recharged from an external source in an emergency, such as a hand pump or a portable air compressor. The Coffman starter was the most common brand of cartridge starters during the mid-1930s, and the name was used as a generic description. Advances in electrical technology have made shotgun starters obsolete for most uses.
