    摘要: A thrust reverser is disclosed for an aircraft turbojet engine having a cowling with an inner surface forming an outer boundary of a gas flow duct, the cowling having at least one reverse thrust opening and a thrust reverser door pivotally attached to the cowling so as to move between a forward thrust position, wherein the thrust reverser door closes the at least one reverse thrust opening and a reverse thrust position, wherein a forward portion of the thrust reverser door moves outwardly from the cowing and a rear portion of the door moves inwardly into the gas flow duct so as to redirect a first portion of the gases flowing through the gas flow duct through the reverse thrust opening. The thrust reverser also includes a passageway bounded at least in part by the rear portion of the thrust reverser door located in the gas flow duct when the thrust reverser door is in the reverse thrust position, the passageway enabling a second portion of the gases flowing through the gas flow duct to pass to the rear of the thrust reverser door and to redirect this second portion of gases in an oblique direction relative to the gas flow duct to eliminate any forward thrust developed by the second portion of gases.

    摘要: A thrust reverser is disclosed for a high bypass ratio turbofan jet engine having a cowling with an inner surface forming an outer boundary of a gas flow duct, the cowling having a plurality of lateral openings and a plurality of thrust reverser doors connected to the cowling so as to be movable between forward thrust positions and reverse thrust positions. The thrust reverser also includes a plurality of linear actuators, one linear actuator connected to the cowling and to each thrust reverser door so as to move the thrust reverser doors between their forward and reverse thrust positions. A synchronization system is included in the thrust reverser and interconnects two of the plurality of linear actuators, the synchronization system having an electric motor, a plurality of transmission drive links, each transmission drive link having one end connected to one of the two linear actuators and a second end, and a gear drive mechanism connecting the output of the electric motor to the second ends of the transmission drive links. Operation of the electric motor rotates the transmission drive links to operate the respective linear actuators to move the thrust reverser doors between their forward and reverse thrust positions. The gear drive mechanism and the connections between the transmission drive links and the linear actuators are such that, in the absence of rotation of the transmission drive links, operation of the linear actuators is prohibited, thereby locking the thrust reverser doors in their forward thrust positions.

    摘要: An aircraft gas turbine-engine thrust-reverser specifically designed to withstand impacts possibly caused by objects propelled from the engines around which they are mounted, for instance disk or blade fragments. These impacts have the energy to distort the annular thrust-reverser structure or to break its bracing components. An emergency locking system for such thrust reverser (35) each comprises a hinging latch (38) of which one end is in the form of a hook (40) partly enclosing the lock-interfacing mechanism (43) with the latch (38) being automatically biased into closing by an elastic arrangement (47). Such a configuration allows setting up additional mechanical connections which are able to compensate for any distortion of the thrust-reverser's annular structure or for any ruptured bracing component in the event of impact by an engine piece.
