Abstract:
In a thrust reverser having at least one thrust reverser sleeve that translates between a deployed and stowed positions and a thrust reverser actuation system that translates the thrust reverser sleeve, the thrust reverser further including a stationary element that remains stationary with respect to the thrust reverser sleeve when the thrust reverser sleeve translates, a hook-latch anti-deployment system comprising:(a) a hook member coupled to the thrust reverser sleeve for translation therewith; (b) a latch member coupled to the stationary element of the thrust reverser, the latch member engaging the hook member when the thrust reverser sleeve is in its stowed position to prevent the thrust reverser sleeve from moving from its stowed position; (c) an actuator coupled to the thrust reverser actuation system and to the latch member, the actuator releasing the hook member from the latch member when the thrust reverser actuation system is actuated to deploy the thrust reverser sleeve to the deployed position, wherein the actuator has a shaft having a roller at an aft end, the hook member having an arcuate hook cam in which the roller at the aft end of the shaft is received when the thrust reverser sleeve is in the stowed position and the hook latch anti-deployment system is in a locked position; and upon actuation of the actuator when the thrust reverser actuation system is actuated to extend the thrust reverser sleeve to the deployed position, the actuator retracts the shaft, the roller at the aft end of the shaft of the actuator acting upon the arcuate hook cam of the hook member cams the hook member to a release position.
