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.
The Hucks starter (invented by Bentfield Hucks during WWI) is a mechanical replacement for the ground crew. Based on a vehicle chassis the device uses a clutch driven shaft to turn the propeller, disengaging as the engine starts. A Hucks starter is used regularly at the Shuttleworth Collection for starting period aircraft. [3]
Air-start system; Aircraft engine starting; Auxiliary power unit; C. Coffman engine starter; Cold start (automotive) Compression release; F. Flame-start system;
The other systems used during the period were electric motors (such as those used in automobiles today), inertia starter (cranked either by hand or an electric motor) and compressed-air starters, which operated much like Coffman starters but were powered by pressurized air tanks. Shotgun starters are composed of a breech, into which the ...
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
The Palouste was a very simple unit, its primary purpose being to supply a high flow rate of compressed air to start larger jet engines such as the Rolls-Royce Spey as installed in the Blackburn Buccaneer (this aircraft having no onboard starting system). [2] Air from the centrifugal compressor was divided between external supply (known as ...
All three airships were powered a variety of engines including the Sunbeam Cossack III a derivative of the Cossack with a flywheel, hand or air starter, engine controls and magnetos mounted directly on the engine for access by the engine mechanics. The Cossack 3 was designed with a water-cooled exhaust and speed governor.
A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines.The device allows the pinion gear of the starter motor to engage or disengage the ring gear (which is attached to the flywheel or flexplate of the engine) automatically when the starter is powered or when the engine fires, respectively.
