Patent number: 10724477Abstract: A lock system for a component of a thrust reverser actuation system (“TRAS”), comprising a lock member translatable between a locked position, in which the lock member prevents movement of the thrust reverser component to deploy the thrust reverser actuation system, and an unlocked position, in which the lock member allows movement of the thrust reverser component to deploy the thrust reverser actuation system. The actuator may further comprise a screw shaft and a nut translatable along the screw shaft and operatively connected to the lock member. Rotational movement of one of the screw shaft and the nut causes the nut to translate along the screw shaft and, in turn, the lock member to move between its locked position and its unlocked position.Type: GrantFiled: May 9, 2018Date of Patent: July 28, 2020Assignee: GOODRICH ACTUATION SYSTEMS LIMITEDInventors: Andrew Hawksworth, James Holding
