Abstract: A jet engine comprising an engine, a fan casing and a 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 and a retracted position to define a window between the secondary jet and outside of the nacelle. Inner and outer doors are mounted articulated between a stowed and a deployed position. For each pair of doors, a runner is translationally mobile between a first and second position. Switching each door of the pair from the stowed to the deployed position is mechanically associated with the runner switching from the first to the second position. For each runner, an actuator ensures the translational runner displacement from the first to the second position. Each runner comprises two portions fastened to one another to adjust the mechanism.

Abstract: A turbojet engine comprising an engine, a nacelle comprising a fan case, an intermediate case having a part forming a hub and an outer shroud radially spaced away from the hub by a secondary, or bypass, flow path and fixed to the hub via arms, in which the outer shroud is situated to the rear and in the continuity of the fan case, a fixed structure fixed to the outer shroud, a mobile assembly mounted with the ability to effect translational movement on the fixed structure, and a ramp fixed to the outer shroud and configured to direct the secondary or bypass flow to exit the outer shroud. Such a turbojet engine makes it possible to simplify assembly and among other things, makes it possible to fix the ramp directly to the outer shroud.

Abstract: A ducted fan turbojet including a nacelle including a fixed structure, a thrust reverser system having a frame, a mobile structure fastened to the frame, inner doors and outer doors hinged at the frame. The frame is mobile in translation on the fixed structure between a forward position and a rear position so as to define a window between the fixed structure and the mobile structure, the window being open between a bypass duct and the exterior of the nacelle. Each door is mobile between a stowed position and a deployed position and the mobile structure is assembled hinged on the frame via at least one hinge whose axis of rotation is globally parallel to a longitudinal axis of the ducted fan turbojet.

Abstract: A nacelle having a window open between a secondary jet and the outside of the nacelle and comprising a fixed structure and a thrust-reversing system having a frame and outer doors articulated on the frame. The frame is translationally mobile on the fixed structure between an advanced position and a retracted position. Each outer door is mobile between a stowed position and a deployed position. The nacelle comprises at least one anti-vibration system which comprises a chock fixed to the fixed structure and having a hole, and a finger fixed to the outer door. The finger and the hole are configured so that the finger lodges in the hole when the frame is in advanced position. Such a nacelle makes it possible to limit the vibrations of the outer doors when they are in stowed position and before the mobile frame begins to be displaced to the retracted position.

Abstract: A nacelle for a bypass turbojet engine having a secondary flow path, the nacelle exhibiting an open window between the secondary flow path and the outside of the nacelle and comprising a reverser system comprising doors in which each door is able to move between a stowed position in which the door closes off the window and a deployed position in which the door does not close off the window. For each door, at least one locking system is configured to lock the door in the stowed position, to unlock the door automatically when the door leaves its stowed position and to lock the door automatically when the door arrives in its stowed position.

Abstract: A turbofan with a secondary duct and including a fixed structure and a mobile assembly including a frame with openwork regions. The mobile assembly is translatable between advanced and retracted positions. The openwork regions are positioned across the window in the retracted position. A plurality of blocking doors is provided, each being mobile between stowed and deployed positions. An array of rams move the mobile assembly. A cascade grille mounts on the frame across the openwork region. The grille slides on the frame parallel to the translational direction. For each grille, a rear stop limits rearward movement, and a compression spring pushes the grille to the rear for abutment against a rear stop. For each grille, the fixed structure comprises a stop element against which the grille abuts upon movement from the advanced position to the retracted position.
