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.
