摘要： A thrust reverser for an aircraft propulsion assembly, this reverser including a lower door and an upper door defining, in thrust reversal configuration, a deflection opening, through which a portion of the fluid not serving to produce the thrust reversal of the aircraft can exit the reverser downstream. The downstream edge of the lower door is offset towards the rear with respect to the downstream edge of the upper door so as to orient the fluid flow passing through the deflection opening vertically upwards. When the propulsion assembly is mounted at the rear portion of the fuselage of the aircraft, this makes it possible in particular to improve the supply of the control surface of the aircraft in the landing phase, in particular in crosswind conditions.

摘要： A variable area nozzle assembly for a gas turbine engine includes a fixed structure surrounding an exhaust duct extending along a nozzle centerline. The fixed structure further includes a first lateral side and a second lateral side opposite the first lateral side. The variable area nozzle assembly further includes a nozzle. The nozzle includes a nozzle outlet including a nozzle outlet cross-sectional area. The variable area nozzle assembly further includes a thrust reverser system including a first thrust reverser door and a second thrust reverser door. The first thrust reverser door is pivotably mounted to the fixed structure at the first lateral side. The second thrust reverser door is pivotably mounted to the fixed structure at the second lateral side. The first thrust reverser door and the second thrust reverser door define a portion of the nozzle outlet of the nozzle.

摘要： A seal interposed between a turbojet engine and a movable part of a nacelle includes a tubular body delimiting an inner cavity interposed between at least one fixing part and a platform. The platform includes a first lateral edge, a second lateral edge and a planar surface extending from the first lateral edge to the second lateral edge. The seal includes a protuberance arranged on the platform. The protuberance is centered on the platform or extends from the first lateral edge to the second lateral edge.

摘要： An actuator operable to drive a thrust reverser in a gas turbine engine, wherein the thrust reverser comprises first and second translatable sleeves. The actuator comprises a first actuating member moveable so as to translate the first sleeve and a second actuating member moveable so as to translate the second sleeve. The actuator further comprises an interlock arrangement operable in a locked mode in which the first actuating member and second actuating member are locked so as to move together and in an unlocked mode in which at least one of the first actuating member and second actuator member is free to move independently of the other. Operation of the actuator to open or close the thrust reverser comprises a first mode wherein the interlock arrangement is in the locked mode and a second mode wherein the interlock arrangement is in the unlocked mode.

摘要： A propulsion system includes a bypass turbine engine and a pylon. The turbine engine includes an engine, two internal cowls, two outer cowls, a first lock for locking the internal cowls to the engine, cascades of vanes fixed to the outer cowl via hooping, wherein the outer cowls are movable in translation with respect to the engine, in which each outer cowl is able to slide parallel to a direction of translation on an internal cowl via a top guideway connection and a bottom guideway connection, and in which each outer cowl is mounted with the ability to slide parallel to the direction of translation on the pylon via an upper guideway connection. The propulsion system makes it possible during maintenance operations to move the outer cowl and the internal fixed structure towards the rear and therefore away from the front cowls to get at the engine.

摘要： An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a folding linkage. The translating structure is configured to move between a stowed position and a deployed position. The blocker door is pivotally attached to the translating structure at a first pivot joint. The folding linkage links the blocker door to the fixed structure. The folding linkage includes a member pivotally attached to the blocker door at a second pivot joint that is radially outboard of a skin of the blocker door when the translating structure is in the stowed position. The second pivot joint is radially outboard of the first pivot joint when the translating structure is in the stowed position.

摘要： Actuator assembly includes a housing assembly, a ball screw, a ball nut, and a lock. The ball screw is rotationally mounted on and extends from the housing assembly, is coupled to receive an actuator drive torque, and is configured, upon receipt thereof, to rotate. The ball nut is rotationally supported on the ball screw and is configured, in response to rotation of the ball screw, to translate thereon between a stowed position and a deployed position. The lock is disposed at least partially within the housing assembly and is configured to move between a lock position and an unlock position. The lock prevents the ball nut from translating out of the stowed position when the lock is in the lock position and the ball nut is in the stowed position.

摘要： A engine comprising a fan casing and a nacelle, the nacelle comprising a fixed structure and a thrust reversing system having a mobile assembly with a mobile cowl and a frame. The mobile assembly is translationally mobile on the fixed structure between an advanced position and a retracted position to define a window between the secondary jet and the outside of the nacelle. Inner and outer doors are mounted articulated between a stowed position and a deployed position. For each pair of doors, a runner is translationally mobile between a first and a second position. The switching from the stowed position to the deployed position of each door is mechanically associated with the switching of the runner from the first position to the second position and vice versa. For each runner, an actuator ensures the translational displacement of the runner from the first position to the second position.
