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 the fact that, based on the measured air temperature at the engine inlet and the air pressure behind the compressor, the afterburner fuel consumption Gt_SPR is calculated to ignite the afterburner combustion chamber, the afterburner fuel consumption Gt_SPR is fed into the starting manifold of the afterburner combustion chamber, and the ignition unit of the afterburner and control the ignition of the afterburner, while using the measured air temperature at the engine inlet and the air pressure behind the compressor, the main flow rate Gt_MAIN of the afterburner fuel into the afterburner start manifold is additionally calculated, until the ignition of the afterburner is confirmed, it is fed into the start manifold is the flow rate Gt_SPR of afterburner fuel for ignition of the afterburner combustion chamber, and after confirming the ignition of the afterburner combustion chamber, the main flow rate Gt_MAIN is supplied to the start manifold.

EFFECT: improving the quality of control of a gas turbine engine by expanding the area of stable operation of the afterburner while maintaining the value of the minimum afterburner thrust.
