Abstract: An actuator for a thrust reverser includes a ball screw, a ball nut coupled to the ball screw, and a gerotor coupled to the ball screw. The gerotor includes an inner rotor coupled to the ball screw and an outer rotor. The outer rotor includes a plurality of bores. The actuator includes a lock system coupled to the outer rotor. The lock system is to enable the gerotor to rotate the ball screw in an unlocked state and to inhibit a rotation of the ball screw in a lock state. The lock system includes a piston coupled to a piston housing and a grippable member coupled to the piston housing. The piston is received in one of the bores in the lock state, and the grippable member is to move the piston housing relative to the gerotor to move the lock system to the unlocked state.

Abstract: A system for coupling a shroud to a case associated with a gas turbine engine includes the case having a mounting pad, and the shroud having a surface that faces the case. The system includes a load spreader having a spreader surface in contact with the surface of the shroud and a locator pin coupled to the mounting pad and the load spreader to couple the shroud to the case. The system includes a load spreader retainer coupled to the load spreader. The load spreader retainer is to distribute a force to the load spreader. The system includes a biasing system coupled about the mounting pad that includes a spring arm configured to apply the force to the load spreader retainer to maintain the spreader surface of the load spreader in contact with the surface of the shroud.
