Electric control system for a turbojet engine thrust reverser including an electromechanical drive device and a locking device which are controlled by an electronic control unit

An electric control system for a turbojet engine thrust reverser having at least one movable component movable between a forward thrust position and a reverse thrust position, the system comprising:

• a) at least one electromechanical drive device mechanically connected to the at least one movable component such that actuation of the electromechanical drive device moves the at least one component between the forward and reverse thrust positions, the electromechanical drive device comprising a screw jack linear actuator having a movable element moving the at least one component between the forward and reverse thrust positions and an electric drive motor electrically connected to an electronic control unit;
• b) the electronic control unit electrically connected to the at least one electromechanical drive device and to a turbojet engine control system to transmit actuation signals to the at least one electromechanical drive device to thereby control the movement of the at least one component between the forward and reverse thrust position;
• and,
• c) a step-down near drive mechanism connected between the electric drive motor and the screw jack linear actuator.
