  • Patent number: 11952963
    Abstract: A thrust reverser for a turbojet aircraft nacelle includes a fixed structure, a movable structure and an actuator. The actuator extends along a main axis and is connected by a first connection to the fixed structure and by a second connection to the movable structure for the deployment of the movable structure between a direct jet position and a reverse jet position. The actuator is also connected to the fixed structure by a third connection arranged longitudinally between the first connection and the second connection. An axis of the third connection is radially eccentric from the main axis and the third connection allows a predetermined displacement of the actuator with respect to the fixed structure.

  • Publication number: 20240093661
    Abstract: A thrust reverser with movable grids, includes structure for connecting, by recessing, a front frame of an outer cowl and a rear frame of the grids. The reverser includes loading structure configured to exert a stress pressing against the connecting structure, under the action of a circumferential pull of the front frame of the outer cowl or of a tightening band supported by the front frame.

  • Publication number: 20230313755
    Abstract: A thrust reverser for a propulsion unit, incudes movable grids, two half-assemblies forming part of a secondary stream and, at the six o'clock position, a connecting beam intended to be mounted in cantilever with a fan housing. The half-assemblies are hinged at the twelve o'clock position so as to enable their “butterfly” movement between a flight configuration and a maintenance configuration. The connecting beam includes a connecting member configured to cooperate, in the form of a tenon and groove connection, with the half-assemblies when these are in flight configuration. The reverser also includes, downstreamof the connecting member, locks capable of locking the half-assemblies in flight configuration.
