METHOD FOR CONTROLLING THE SUPPLY OF FUEL TO THE COMBUSTION CHAMBER OF A GAS TURBINE ENGINE Russian patent published in 2022 - IPC F02C9/00 F04D27/00 

FIELD: aircraft engine building.

SUBSTANCE: invention relates to the field of aircraft engine building. The method for controlling the fuel supply to the combustion chamber of a multi-shaft gas turbine engine (GTE) consists in selecting at least two adjustable parameters of the engine operation, during engine operation, the current values of each of the adjustable parameters of the GTE operation, the temperature Tin of the air at the GTE inlet and the position of the engine control lever, for each of the selected adjustable parameters their maximum allowable values are formed, from the selected adjustable parameters, those are selected for which their minimum allowable values are formed, and for each of these selected adjustable parameters, depending on the position of the throttle, a predetermined value of the adjustable parameter in the range from the minimum to the maximum allowable values of this adjustable parameter, deviations of the current values of the controlled parameters from their maximum allowable and specified values are measured, and for each of the deviations, the rate of change in fuel consumption is formed to eliminate the deviation of the controlled parameter, the maximum and minimum values are selected from the rates of change in fuel consumption, the fuel consumption in the GTE is formed by integrating the selected speed dG changes in fuel consumption and feeds the generated fuel consumption into the combustion chamber of the gas turbine engine.

EFFECT: improving the quality of GTE controllability and ensuring the reliability of GTE operation by regulating several parameters of GTE operation subject to restrictions on their minimum and maximum values.
