Abstract: A thrust reverser for an aircraft propulsion assembly, comprising a membrane for sealing off a secondary flow path, as well as at least one deployment connecting rod for deploying this membrane, which is designed to be moved from a first position projecting radially into the secondary flow path when the mobile structure is occupying its advanced direct-thrust position, to a second position folded down toward the downstream direction when the mobile structure is occupying its retracted thrust-reversal position. According to the invention, the reverser also comprises a device for actuating the connecting rod, the reverser being configured such that during an initial phase of movement of the mobile structure from its advanced direct-thrust position towards its retracted thrust-reversal position, the actuating device causes a first articulated connection of the connecting rod to move radially inwards and/or axially upstream.

Abstract: An assembly for a propulsion unit including a stationary surface, a surface movable relative to the stationary surface, and a linking system to link the stationary surface and the movable surface and to allow the accommodation of a movement of the movable surface relative to the stationary surface. The linking system includes a linking device connected to the stationary surface, and a locking device connecting the linking device to the movable surface and including a fitting on which the linking device is mounted. The locking device, in an unlocking position, facilitates the displacement of the fitting relative to the movable surface during a movement of the movable surface relative to the stationary surface.

Abstract: A thrust reverser for an aircraft propulsion unit, including a fixed structure, at least one cowl and a plurality of cascades of deflection vanes, the cowl and the cascades of vanes forming a system capable of translational movement relative to the fixed structure along a longitudinal central axis, the mobile system further including at least one rear cascade-support structure to which a rear end of the cascades of vanes is fixed, the rear structure extending in a circumferential direction of the reverser. The rear structure incorporates an acoustic-absorption device including an array of cells and a skin covering the cells, the skin having a first surface arranged facing the cells, and a second surface bounding part of a secondary flow path.
