  • 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.

  • Publication number: 20230046876
    Abstract: A thrust reverser including a stationary structure, a lower door and an upper door. This reverser includes at least one deflector configured to be able to redirect forward from the stationary structure a portion of fluid exiting the reverser according to a trajectory oriented towards a lateral opening extending between the stationary structure and the upper door. Such a deflector makes it possible to improve the control of the air current lines acting on a tail unit and in particular on a control surface of an aircraft equipped with such a reverser when the latter is in thrust reversal configuration, thereby making it possible to improve the controllability of this aircraft.

  • Patent number: 9617955
    Abstract: The present disclosure relates to a cascade thrust reverser providing that when a sliding cowl and a flap are in a direct jet position, a hook is held in engagement with another hook and the flap is immobilized inside of a housing of the sliding cowl by a stem of a telescopic connecting rod subjected to pre-stress generated by a compressed spring located in the body of the connecting rod. When the sliding cowl starts to slide from the direct jet position toward the reverse jet position, the hooks disengage each other and the stem engages with an extension in the body of the connecting rod, so that the flap is rotated from the direct jet position toward the reverse jet position due to the tensile force exerted by the stem.
