    摘要: A turbojet thrust reverser includes two doors each displaceable between an open position and a closed position of the reverser by at least one respective control actuator. Two electric motors drive the control actuators for the doors; each motor being controlled by an electronic control unit connected to a full authority digital engine control. Two servo-control devices control the displacement of the doors as a function of determined position references. The servo-control devices enable the doors to be displaced synchronously as a function of any variation in the forces exerted on the reverser and as a function of any force difference between the two doors.

    摘要: Each manual control unit for a moving part of a thrust reverser is associated with a maintenance plate that is pivotable between at least two positions: a first or “normal operation” position in which said plate prevents the manual control unit with which it is associated from being driven manually, while allowing it to be driven electrically; and a second or “maintenance” position in which said plate allows the manual control unit with which it is associated to be driven manually while preventing it from being driven electrically.

    摘要: The actuator assembly comprises a master actuator and at least one slave actuator having a cylinder containing a piston defining two chambers in the cylinder. A first chamber of the slave actuator is connected to an outlet of a directional control valve which is connected to a hydraulic control circuit and to a control member whose position determines the pressure in the first chamber of the slave actuator. A displacement of the piston of the master actuator is transferred to the control member of the control valve associated with the slave actuator by means of a mechanical transmission such as a flexible linear rolling bearing. Thus, the displacement of the piston of the slave actuator is servo-controlled to the displacement of the piston of the master actuator by controlling the position of the control member of the control valve associated with the slave actuator. The actuator assembly is suitable for use in particular for controlling the moving flaps of the nozzle of a turbojet of variable exhaust section, and possibly also steerable.
