GAS TURBINE ENGINE CONTROL METHOD Russian patent published in 2022 - IPC F02C9/28 

FIELD: gas turbine engines.

SUBSTANCE: invention relates to the field of controlling the operation of gas turbine engines (GTE), mainly aircraft, and can be used to control the supply of fuel to the GTE. The gas turbine engine control method consists in the fact that according to the readings of the turbocharger rotor speed sensors and the air temperature at the engine inlet, the reduced value of the turbocharger rotor speed is formed. Depending on the pressure downstream of the compressor and the reduced speed of the turbocharger, a predetermined value of the rate of change in the speed of the turbocharger rotor and the maximum specified fuel flow into the combustion chamber are formed. Based on the measured value of the turbocharger rotor speed and the predetermined rate of change in the turbocharger rotor speed, a predetermined value of fuel consumption in the main combustion chamber is formed. According to the sensor readings, the fuel consumption is determined, compared with the specified one, and by the magnitude of the mismatch between the specified and measured values, a control action on the fuel consumption is formed and the fuel consumption in the combustion chamber of the gas turbine engine is limited to the maximum specified consumption. Additionally, the air pressure at the engine inlet is measured, when the air pressure at the engine inlet drops below the preselected value and the maximum fuel consumption is reached, the latter increases relative to the nominal level, otherwise it decreases to the nominal level at a preselected constant rate.

EFFECT: ensuring a stable acceleration time and achieving the parameters of the maximum mode in all engine operating conditions and as the resource is depleted.
