摘要： A backup locking system for a thrust reverser door comprises a catch pivotally mounted by a pivot pin to a fixed structure of the thrust reverser. A hook with a self-locking profile is provided at the free end of said catch for cooperation with a locking interface on the door in the event of failure of the normal locking systems. At its other end remote from said hook, the catch has a heel ending in a part-cylindrical surface which is concentric with said pivot pin. The catch is urged against the locking interface by a piston rod which presses against a front face of said heel under the force of a spring acting on a piston to which said piston rod is attached. When the rod is retracted, a double lever positively moves the catch toward a minimum opening angle, at which point the door can be opened. An unlocking spring causes the full opening of the catch to maximum open position when an opening lever is released. The piston rod presses against the cylindrical surface of the heel when the catch is open, which renders the piston spring inoperative. The opening lever is connected to the catch by link rods and includes a stop to limit the angle of opening of the catch.

摘要： In a turbojet thrust reverser comprising, in an annular section of an outer cowling of the turbojet, a number of movable doors which, in an inactive position during operation in a forward thrust configuration, close off passages separating rigid spars of a fixed structure, there is provided, between two adjacent doors, a locking system which allows substantially simultaneous opening of the two doors. The locking system comprises, for each door, at least one hook mounted on the fixed structure so that it can be pivoted by an olive secured to the door between a door locking position and an unlocked position during opening or closing movement of the door. The two hooks of the locking system are rotationally interlinked by a mechanical linkage device, for example link rods, so as to prevent the unlocking of one door if the other door is closed.

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 latching mechanism is disclosed for a jet engine thrust reverser having a thrust reverser door movably connected to an engine cowling with a reverse thrust opening, the thrust reverser door being movable between a forward thrust position, in which the thrust reverser door covers the reverse thrust opening, and a reverse thrust position, in which the reverse thrust opening is uncovered. The latching mechanism has a lock bar mounted on the thrust reverser door, the lock bar having a distal end, and a latch member pivotally located on the cowling, the latch member having a slot engaged by the distal end of the lock bar when the thrust reverser door is in the forward thrust position. The latch member is movable between a latched position, in which the latch member prevents disengagement of the distal end of the lock bar from the slot, so as to lock the thrust reverser door in the forward thrust position, and an unlatched position which permits disengagement of the distal end of the lock bar from the slot. The latching mechanism also includes a hook member connected to the cowling and located so as to engage the distal end of the lock bar upon relative movement between the cowling and the thrust reverser door away from each other in a direction generally parallel to a longitudinal axis of the cowling, such engagement preventing disengagement of the distal end of the lock bar from the slot and displacement of the thrust reverser door from the forward thrust position.

摘要： A variable turbofan bypass cowling includes a movable cowling assembly (12) with pivoting door type thrust reversers (20) connected to a fixed upstream cowling structure (11). The movable assembly may be translated between an upstream position whereat an upstream portion of the reverser and cowling assembly (12) is housed inside an enclosure formed by the upstream cowling structure (11) and a downstream position whereat the assembly (12) effects a variation in the exhaust duct (17) cross-section between an inner primary turbojet-engine cowling (15) and a radially inner wall of the assembly (12). The reverser doors (20) in their closed position are integrated into the cowling wall and contain at least part of the exhaust flow. When pivoted to thrust reversed positions following translation of the assembly (12) to a downstream rearward position, thrust reversal is provided in the usual manner.

摘要： The present invention relates to a thrust reverser for a turbojet engine having a cowling bounding a flow duct through which gases flow from the front of the cowling towards a rear of the cowling, the cowling having at least one reverse thrust opening communicating with the gas flow duct. The thrust reverser has a thrust reverser door pivotally mounted on the cowling so as to be movable between a forward and a thrust position, wherein the thrust reverser door covers the reverse thrust opening, and a reverse thrust position wherein the thrust reverser door uncovers the reverse thrust opening and directs at least a portion of the gases flowing through the gas flow duct outwardly through the reverse thrust opening. A vane having an air foil cross-sectional configuration is connected to the thrust reverser door and is located so as to be acted on by the gases passing through the gas flow duct when the thrust reverser door is adjacent to its forward thrust position, such that the vane exerts a force on the thrust reverser door urging it toward its forward thrust position.
