Electrical Control of Lift Engine Throttles 630080

Justifying the use of electric control systems for such an important duty as control of lift engines (in, say, VTOL transport) and elimination of a mechanical linkage must devolve on past experience, as regards both technical capabilities and reliability. This paper describes an electrical engine control that has extensive service experience and discusses its reliability record. A more modern control is also described, to illustrate available techniques. In addition, the requirement peculiar to jet lift engines, and the engine failure case, are demonstrated by a typical system for multi-engine aircraft. Some suggestions for instrumentation and display are given.
