A system is disclosed for closing a pivoting door thrust reverser pivotally attached to a jet engine cowling including a latch mechanism that is movably connected to the jet engine cowling and movable between a first position in which the latch grips a forward portion of the thrust reverser door when the forward portion of the thrust reverser door is a predetermined distance from the fully closed position and a second position in which the latch mechanism exerts a force on the thrust reverser door to urge the thrust reverser door to the fully closed position. In this manner, a relatively large closing torque is exerted on a forward portion of the thrust reverser door by the movable latch mechanism. Since the force is applied a relatively large distance from the pivot axis of the thrust reverser door, the requisite torque may be generated by actuator having a relatively low force.

[ We claim:] [1.]1. A closure system including a pivoting thrust reverser door pivotally attached to a jet engine cowling so as to move between a fully closed forward thrust position and a fully open reverse thrust position, the jet engine cowling forming a reverse thrust opening that is covered by the thrust reverser door when in the fully closed forward thrust position, the thrust reverser door having a forward portion extending outwardly from the jet engine cowling when in the fully open reverse thrust position, the system comprising:a locking mechanism including a latch which is movably connected to the jet engine cowling, said latch being movable between a first position in which the latch releases the thrust reverser door, a second position in which the latch grips the forward portion of the thrust reverser door when the thrust reverser door is at a partially open position a predetermined distance from the fully closed forward thrust position, and a third position in which the latch exerts a force on the thrust reverser door and thereby moves the thrust reverser door from the partially open position to the fully closed forward thrust position; anda latch moving device arranged to move the latch from the second position to the third position, the latch being arranged such that upon such movement the latch exerts a force on the thrust reverser door and moves the thrust reverser door from the partially open position to the fully closed forward thrust position.
