Abstract

A thrust reverser is disclosed in which a panel is pivotally attached to the cowling downstream of the movable thrust reverser door and is connected to the door such that movement of the thrust reverser door causes the panel to pivot about its attachment to the cowling. When the door is in its forward thrust position, the inner wall of the door and an inner wall of the panel form a portion of the boundary of the duct through which pass pressurized gases. The pressurized gases exert forces on the inner wall of the door and the inner surface of the panel such that the forces urge the thrust reverser door toward its forward thrust position. Thus, the thrust reverser door is prevented from being inadvertently deployed toward its reverse thrust position even upon failure or malfunction of the door locking or latching mechanisms.
