Abstract
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.
