An electric starter with sufficient power to turn a large diesel engine would itself be so large as to be impractical so there is a need for an alternative system. An air start system has three main components along with various safety components, namely the air start injector, the distributor and the air receivers.
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 ...

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.
Klimov TV3-117 turboshaft engine. The accessory drive is the large casting on the top. The accessory drive is a gearbox that forms part of a gas turbine engine. [1] Although not part of the engine's core, it drives the accessories – such as generators, pumps for fuel and lubrication oil, air compressors, hydraulic pumps and engine starters – that are otherwise essential for the operation ...
This can in turn affect performance under extreme conditions and therefore flight safety certification. Some modern types, such as the Airbus A400M, have counter-rotating propellers in order to meet air safety requirements under engine-out conditions.
The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled, petrol-powered radial engine. Producing 360 hp (268 kW), its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus.
Much more effective is the H-gutter flame holder, which is shaped like a letter H with a curve facing and opposing the flow of air. Even more effective, however, is the V-gutter flame holder, which is shaped like a V with the point in the direction facing the flow of air.
