METHOD FOR CONTROLLING THE REVERSER APPARATUS OF A GAS TURBINE ENGINE Russian patent published in 2022 - IPC F02K1/76 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aircraft engineering, in particular, to methods for controlling the reverser apparatus (RA) of a gas turbine engine (GTE) on aerial vehicles when the aircraft breaks after landing (touchdown) and interrupted takeoff. Method for controlling the reverser apparatus (RA) of a gas turbine engine (GTD), including the input of information of the aircraft's presence on the ground after landing to the electronic engine controller (FADEC) from the control and monitoring subsystem of the GTE RA; setting of the thrust lever to the Idle platform and then to the Minimum reverse thrust platform, wherein the control and monitoring subsystem of the GTE RA issues a command signal to actuate the solenoid of the electromechanical lock of the GTE RA and power the electrohydraulic shutoff apparatus of the GTE RA controlled by the FADEC according to algorithms, wherein the commands from said apparatus, after the electromechanical lock and the electrohydraulic shutoff apparatus of the GTE RA are triggered, initiate the release of the GTE RA into the Reverse thrust position; wherein a command signal is formed and issued in the control and monitoring subsystem of the GTE RA by concentrator computing units information about the engine mode corresponding to Minimum reverse thrust and signals from the limit switches of the thrust lever position are received from the FADEC, followed by forming and issuing commands to close the keys in the protection and switching units to actuate the solenoid of the electromechanical lock of the GTE RA and direct electricity to the electrohydraulic shutoff apparatus of the GTE RA.

EFFECT: higher reliability of the GTE RA control system and flight safety at all stages of operation of the aircraft, including regular landing of the aircraft with the activated GTE RA and during interrupted takeoff due to the improved diagnostics and deep monitoring of the technical condition of the GTE RA and the products involved in the control of the GTE RA.
