METHOD OF CONTROLLING FUEL FEED INTO GAS TURBINE ENGINE Russian patent published in 2013 - IPC F02C9/26 

Abstract RU 2474712 C2

FIELD: engines and pumps.

SUBSTANCE: invention may be used in gas turbine engine automatic control systems. In aircraft takeoff, minimum tolerable power magnitude is formed additionally by throttle position to compare minimum tolerable engine power with engine available power. obtained mismatch is sent to PI-controller, instead of selected magnitude. In case it is impossible to define minimum tolerable engine power or engine available power, magnitude of minimum tolerable air pressure downstream of engine compressor is formed as function of throttle position and engine inlet air pressure. Now, minimum tolerable magnitude is compared with measured air pressure downstream of compressor to output obtained mismatch to PI-controller.

EFFECT: higher quality of control, hence, higher reliability and safety.
