A recuperated gas turbine engine control and method which provides improved idling and limits both turbine inlet temperature and recuperator inlet temperature to different, preselected maximum levels.

Control for turbine and recuperator inlet temperatures

A free turbine gas turbine engine with an automatic idle reset control and method which anticipates requirement for engine acceleration and increases idle speed before request for acceleration is received.

Gas turbine engine idle control and method

A control system for a gas turbine engine includes provisions for adjusting fuel flow in relation to gas generator speed, and for adjusting guide vane position in relation to power turbine speed.

Gas turbine engine fuel control

A recuperated gas turbine engine fuel and guide vane control which controls fuel flow and guide vane position during engine idling and acceleration to minimize fuel consumption while providing fast acceleration for a ground vehicle.

Variable geometry gas turbine engine fuel and guide vane control

A free turbine engine for driving ground vehicles with various deceleration or braking actions including power feedback braking wherein the turbine compressor is selectively interconnected with the power output shaft only in such a manner whereby compressor inertia assists in decelerating the vehicle.
