Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, a door, a main actuator, and an assist actuator. The transcowl is mounted on the support structure and is axially translatable between a stowed position and a deployed position. The door is pivotally coupled to the support structure and is rotatable between at least a first position and a second position when the transcowl translates between the stowed position and the deployed position, respectively. The main actuator is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The assist actuator is coupled to the door, and is configured to supply an actuation assist force to the door and, upon rotation of the door to an intermediate position between the first position and the second position, to commence load sharing with the main actuator.

Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, and an actuator. The transcowl is mounted on the support structure and is axially translatable between a stowed position and a deployed position. The actuator is coupled to the transcowl and the support structure, and is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The actuator includes an actuator housing, a screw, a nut, a rod end, and a tension rod. The tension rod is engaged by the nut when the transcowl is in the deployed position and is engaged by the rod end when the transcowl is in the stowed position, whereby actuator loads, in both the deployed and stowed positions, are transmitted through the tension rod to the support structure.

Abstract: An aircraft engine nacelle door operating system locking manual drive unit includes a housing, an input drive shaft, an output drive shaft, a lock shaft, and a lock spring. The input drive shaft, the output drive shaft, and the lock shaft are all rotationally mounted in the housing. The output drive shaft continuously engages and mates with the input drive shaft, and he lock shaft extends at least partially into and engages the input drive shaft. The lock shaft is movable between a lock position, in which it engages and mates with the output drive shaft, and an unlock position, in it is disengaged from the output drive shaft. The lock spring supplies a bias force to the lock shaft that urges the lock shaft toward the lock position.
