摘要： 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 The guide channel causes the latch member to maintain the spring loaded shear pin in a withdrawn position when the kicker plate is returned its stowed position as the reverser door is returned to its stowed position.

摘要： A thrust reverser for a turbojet engine comprising displaceable downstream baffles (2) which are integrated into the outer wall of the annular bypass-flow duct so as to form the downstream end of the exhaust nozzle of the turbojet engine during the operation of the turbojet engine in a forward-thrust mode is provided. When in a thrust-reversal mode, the downstream baffles (2) are positioned so as to deflect the bypass flow and obtain thrust reversal. The baffles (2) are pivotably mounted on stationary pivots (10) and have at least one associated displacement mechanism (6, 7) for driving the baffles (2). Each downstream baffle (2) has an associated displaceable inner panel (13). Each baffle (2) and the associated inner panel (13) are driven through different angular displacements by the at least one associated displacement mechanism (6, 7), which is common to the baffle (2) and the associated inner panel (13), to change between the forward-thrust mode and the thrust-reversal mode. The at least one associated displacement mechanism (6, 7) is preferably mounted in a stationary manner on a stationary structure of the thrust reverser.

摘要： A thrust reverser system includes one or more actuators each having a locking mechanism that prevents unintended actuator movement, and thus unintended thrust reverser movement. Each of the actuators additionally includes a lock inhibitor assembly that engages the lock and prevents it from moving to its locked position until the actuator is moved into a stow position. Upon movement to the stow position, the lock inhibitor assembly disengages the lock, and the lock automatically moves into its locked position.
