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]
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine.
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 engine nose cone, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
Many modern aircraft use single-lever power control (SLPC) system, where on-board computer automatically manages the propeller speed based on the desired power setting and operational conditions. The output power from the propeller is equal to a product of propeller efficiency and input power from the engine.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
The fuel system as explained above is one of the two systems required for starting the engine. The other is the actual ignition of the air/fuel mixture in the chamber. Usually, an auxiliary power unit is used to start the engines. It has a starter motor which has a high torque transmitted to the compressor unit. When the optimum speed is ...
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.
