ELECTROMECHANICAL SYSTEM FOR CONTROLLING THE REVERSER APPARATUS OF A GAS TURBINE ENGINE Russian patent published in 2021 - IPC F02K1/76 

Abstract RU 2757949 C1

FIELD: controlling.

SUBSTANCE: invention relates to FADEC-type electromechanical systems for controlling the reverser apparatus of a gas turbine engine (GTE). The electromechanical system for controlling the reverser apparatus of a gas turbine engine (system) comprises an electronic engine controller (EEC), an electronic unit for controlling electromechanical drive bodies, at least one electromechanical drive body unit for opening or closing the reverser apparatus (RA), including at least an electric engine, a screw transmission and an electric engine locking mechanism; a position sensor for the movable part of the RA, an electromechanical lock of the RA, a position sensor for the electromechanical lock of the RA, an engine control lever with a switch for switching the electric circuit of the electromechanical after transferring the engine control lever to the RA operation platform, wherein the output of the EEC is connected with the input of the electronic control unit, the first output of the electronic control unit is connected with the electromechanical drive body unit, and the second output of the electronic control unit is connected with the input of the EEC; an on-board system for recording and indicating the flight information parameters. Additionally introduced is a position sensor for the engine control lever, connected with the EEC, the outputs of the position sensor of the electromechanical lock of the RA are connected with the inputs of the EEC; the EEC comprises at least two control channels, the electronic control unit comprises at least two control channels; wherein the EEC is capable of exchanging information between the channels of the electronic controller and transmitting information to the on-board system for recording and indicating the flight information parameters; the electronic unit for controlling the electromechanical drive is capable of exchanging information between the channels of the electronic control unit, as well as identifying a failure of the electromechanical drive body unit and transmitting information about the serviceable condition of the electromechanical drive body unit to each channel of the EEC. The electronic control unit therein is also capable of transmitting the information about the operation of the electromechanical drive of the RA to the on-board system for recording and indicating the flight information parameters; and the position sensor for the movable part of the RA is capable of measuring the current position of the movable part of the RA.

EFFECT: proposed invention provides a possibility of increasing the reliability and fault safety of the electromechanical system for controlling the reverser apparatus, increasing the flight safety, reducing the mass of electrical communication lines, operating costs and the general complexity of the gas turbine engine.
