Abstract
An electric control system is disclosed for a turbojet engine thrust reverser having at least one movable component movable between a forward thrust position and a reverse thrust position, the control system having at least one electromechanical drive device mechanically connected to the moveable component such that actuation of the electromechanical drive device moves the component between the forward and reverse thrust positions, and an electronic control unit electrically connected to the electromechanical drive device and to a turbojet engine control system to transmit actuation signals to the electromechanical drive device to control the movement of the component between the forward and reverse thrust positions. The electronic control system preferably also has at least one electrically actuated locking device to hold the movable component in the forward thrust position.
