APPARATUS FOR CONTROLLING THE REVERSAL OF THRUST OF THE GAS TURBINE ENGINE OF A PLANE Russian patent published in 2022 - IPC F02K1/76 F02C9/16 F02C7/57 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engineering, in particular, to apparatus for controlling the reversal of thrust of a gas turbine engine (GTE) on aircraft of any capacity and purpose (passenger; transport; military transport) during braking after landing and aborted takeoff. Claimed advantages are provided by an apparatus for controlling the reversal of thrust of the GTE of a plane, containing an indication and recording module; a TCL with a two-channel angular position sensor, two independent limit switches of the TCL position, power supply closing switches, a reversal activation apparatus containing a reverse latch, a return spring, a rod, a forward and reverse thrust reverse switch; a CL control and monitoring circuit containing two identical and independent main and backup concentrator computer units equipped with identical and independent main and backup channels, two identical and independent main and backup protection and switching units equipped with identical and independent main and backup channels, two identical and independent main and backup signal converter units, each provided with independent main and backup channels; the hydraulic system of the plane; a GTE CL with a shutoff electrohydraulic apparatus of the GTE CL, mechanical locks of the GTE CL with a control solenoid for the hydraulic apparatus of the GTE CL and the electrohydraulic drives of the GTE CL; FADEC; a block of sensors and alarms of the GTE CL, equipped with an alarm of the mechanical lock of the GTE CL, a HS pressure sensor, an alarm of the mechanical lock of the electrohydraulic drive of the GTE CL, and a GTE CL position sensor, a power supply system, avionics.

EFFECT: possibility of increasing the reliability and safety of operation of a plane with a GTE and, therefore, reducing the labour intensity of maintenance and the cost of operation.
