METHOD FOR CONTROLLING A GAS TURBINE ENGINE WITH AN AFTERBURNER Russian patent published in 2022 - IPC F02C9/28 F02C9/26 F02C9/00 

FIELD: aircraft engine building.

SUBSTANCE: invention relates to the field of aircraft engine building. The method for controlling a gas turbine engine with an afterburner consists in that, based on the measured air temperature at the engine inlet, the air pressure behind the compressor, the position of the engine control lever, the nominal fuel consumption G_nom is calculated for each collector of the afterburner, and fuel is supplied to the collectors, pre-selected for each manifold, the flow rate G_fill of filling with fuel, during the engine operation, for each of the manifolds, the time τ_fil of filling the manifold is calculated depending on its flow rate G_fill of filling with fuel, the rate of change in fuel consumption dG_t/dt is determined in advance, during the time G_fill the manifold, the selected fuel filling rate G is dosed into the manifold, then the flow into the manifold is changed at a certain rate dG_t/dt to the value of the corresponding nominal flow rate G_nom and the nominal fuel consumption G_nom is dosed in collector.

EFFECT: increasing the reliability of the operation of a gas turbine engine in the modes of switching on the fuel manifolds of the afterburner in the entire area of engine operation due to the optimal change in the fuel consumption dosed into the manifold.
