Title: Pivoting door thrust reverser system for turbofan aircraft jet engine

Abstract: An improved pivoting door thrust reverser system for a turbofan aircraft jet engine having a non-translatable housing and at least one thrust reverser door being pivotable between a stowed forward thrust position and a deployed reverse thrust position. The thrust reverser door is pivotable about a first axis and a kicker plate is hinged to the door at a second axis. As the door is deployed by an actuator a spring loaded roller clamp means keeps the kicker plate clamped to the actuator body until a portion of the kicker plate positively engages the thrust reverser door and the roller clamp means is then disengaged from the actuator body. A pivotable latch member is carried at the front portion of the kicker plate and cooperates with a cam guide channel positioned on the forward bulkhead of the thrust reverser system to allow the pivotable latch member to positively lock the kicker plate to the door after the kicker plate engages the door by an insertion of a spring loaded shear pin through the kicker plate into a lug carried on the door. The guide channel causes the latch member to maintain the spring loaded shear pin in a withdrawn position when the kicker plate is returned its stowed position as the reverser door is returned to its stowed position.
