An actuator for a flight control surface of an aircraft, including: a fixed annulus for fixing to the fuselage, an rotatable annulus with respect to the fixed annulus about an axis of rotation, an output ring which can be fixed to the control surface, and a coupling mechanism having a disc with translational mobility with respect to the mobile annulus in a direction parallel to the axis of rotation, the disc able to move between an engaged position, and a disengaged position, in which the disc is disengaged from the mobile annulus to disconnect the output ring from the mobile annulus. A retaining piece keeps the disc in the engaged position, and a rupture member activates to break the retaining piece to allow the disc to move into the disengaged position.

Aircraft flight control surface actuator

The invention relates to an actuator () for controlling a flight control surface () of an aircraft, comprising:&#x2014;a primary route () comprising a first member () for generating a first torque, and a first drive shaft () having an end () able to be connected to the first member () and an end () able to be connected to the control surface (),&#x2014;a secondary route () comprising a second member () for generating a second torque and a second drive shaft () having an end () able to be connected to the second member () and an end () able to be connected to the control surface (), in which actuator the second drive shaft () is hollow and extends around the first drive shaft ().

Actuator for controlling a flight control surface

A device for controlling the power of an engine and of a thrust reverser device. The invention includes a frame on which a primary cam track is formed, a thrust lever hinged to the frame, a thrust reverser lever hinged to the thrust lever, a bearing face arranged on the thrust reverser lever, a locking lever hinged to the thrust lever and comprising a first end and a second end. When the thrust lever has been pivoted by a predefined angle relative to the idle position of same, actuation of the thrust reverser lever is blocked, both by the second end of the locking lever pressing against the bearing face of the thrust reverser lever, and by the first end of the locking lever pressing against the primary cam track.
