A locking/unlocking system for a thrust reverser actuator includes a preloading arrangement mounted between a locking part and an input gear of an actuator drive mechanism, the preloading arrangement holding the locking part and the input gear rotationally fixed when a torque between the drive mechanism and the locking part is less than a preloading threshold and decoupling the locking part and the input gear when the torque becomes greater than the preloading torque, a decoupling movement displacing the locking member from a locked position to an unlocked position, the drive movement then being able to be transmitted in order to allow a deployment of the thrust reverser actuator.

A device includes a lever associated with a body carrying a plate that is connected to the body by a pivot connection for pivoting about a first axis, the lever being connected to the plate by a pivot connection for pivoting about a second axis, a first transmission shaft and a first connection mechanism for connecting the lever to the first transmission shaft, a second transmission shaft and a second connection mechanism for connecting the control lever to the second shaft. The first shaft and the first connection mechanism are connected together by a pivot connection for pivoting about a fifth axis that is inclined relative to the first axis and to the third axis, and the second shaft and the second connection mechanism are connected together by a pivot connection for pivoting about a sixth axis that is inclined relative to the second axis and to the fourth axis.

Device for controlling the flight of an aircraft

An actuating device for moving a mobile cap of a thrust reverser, which includes: an actuator having a first element, such as a screw, and a second element, such as a nut, collaborating with the first element in such a way that turning the first element causes the second element to move in a translational movement. A locking piece is rotationally mobile between a locked position in which the locking piece prevents the first element from turning, and an unlocked position in which the locking piece allows the first element to turn. An unlocking piece is rotationally mobile between an active position in which the unlocking piece urges the locking piece towards the unlocked position and a passive position in which the unlocking piece allows the locking piece to return to the locked position.
