Abstract
Abstract Optimum or most economical air-fuel mixture for a turbine engine is maintained by having the fuel injection system, the ignition system and the pressure air system operate independently of the rotational velocity of the drive shaft of the engine or any of its primary rotating parts. The engine turbine and its drive shaft may be decelerated by placing a high air compression load on the drive shaft.
