METHOD OF CONTROLLING AIRCRAFT GAS TURBINE ENGINE IN TAXIING AND TAKE-OFF RUN MODES Russian patent published in 2024 - IPC F02C9/44 B64D31/12 

FIELD: aviation; aircraft engine building.

SUBSTANCE: method to control aircraft gas turbine engine in taxiing and take-off run modes includes continuous measurement of aircraft speed and limiting air flow through the engine by limiting the reduced speed of the low-pressure compressor rotor depending on the value of the measured speed of the aircraft. Note here that two limiting dependencies of low-pressure compressor rotor rpm are selected for aircraft taxiing and take-off run. When the engine control lever (ECL) position is exceeded, the low-pressure compressor rotor speed is limited according to the aircraft take-off run mode dependence, and at the position of the ECL below the threshold—according to the dependence of the taxiing mode.

EFFECT: higher quality of controllability in taxiing mode while protecting aircraft engine from ingress of foreign objects from taxiway and runway through engine air intake during taxiing and takeoff run.
