Patent number: 11168645Abstract: An actuation device for a thrust reverser includes thrust-reversal movable elements carried by a nacelle and displaceable between a retracted and deployed position. The actuating device includes two actuators mounted on the nacelle and connected to a motor and to the movable elements. The actuation device drives the movable elements in a retraction or deployment direction over a course of the actuators between the retracted and deployed position. The actuation device further includes locks for locking the movable elements in the retracted position and antideployment members associated with the actuators which allow free operation of the actuators in the direction of retraction and retain the actuators in the direction of deployment. The antideployment bodies further provide free operation of the actuators in the direction of deployment over part of the actuators stroke that corresponds to a shift from an over-retraction position to the retraction position of the movable elements.Type: GrantFiled: September 6, 2019Date of Patent: November 9, 2021Assignees: Safran Nacelles, Safran Electronics & DefenseInventors: Hakim Maalioune, Julien Corbin, Jean-Philippe Joignet, Julien Hautecoeur, Yvon Joncour, Jean-Michel Figuet
