METHOD FOR CONTROLLING A GAS TURBINE ENGINE WITH AN AFTERBURNER Russian patent published in 2022 - IPC F02C9/28 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 the fact that the measured air temperature at the engine inlet, the air pressure behind the high-pressure compressor, the position of the engine control lever control the fuel flow into the afterburner, while the measured pressure values air in two given sections of the engine, the current value π of the pressure ratio in the given sections is formed, the nominal value π_nom of the pressure ratio in the given sections is formed, the set value π_set of the pressure ratio in the given sections of the engine is equal to π_nom, the set value the current value of π and the deviation value of π from π_set, obtained as a result of comparison, regulate the position of the valves of the critical section of the jet nozzle of the engine, while when each afterburner fuel manifold is put into operation, for the time of its filling, the set value π_set of the pressure ratio is set values ​​in the given sections of the engine equal to the value of the pressure ratio in the given sections of the engine pre-selected for normal conditions for the corresponding fuel manifold FCC.

EFFECT: increasing the reliability of ignition of the afterburner combustion chamber by coordinating the ratio of pressures in the given sections of the engine.
