A Design Study of the Application of a Simplified Aircraft Fuel Control Method to Automotive Gas Turbines

The results of a design study of the application of a simplified aircraft fuel control method to automotive gas turbines is presented. Although the requirements for control of automotive gas turbines impose a degree of complexity exceeding that of fixed geometry aircraft engines, the hydromechanical computing circuit employed in the earlier application is found to be applicable to the automotive requirements. Methods for compensation and/or adjustment for wide range fuel density and inlet temperature variations and for obtaining turbine vane actuation, acceleration optimization, and turbine braking are presented.
