Electromechanical actuator for an aircraft control surface, and an aircraft provided with such an actuator

An electromechanical actuator for a movable flight control surface of an aircraft, the actuator comprising an electric motor having an outlet shaft with first and second directions of rotation, a movement transmission arranged to connect the outlet shaft of the motor to the movable flight control surface, and a control unit for controlling the motor, wherein the transmission incorporates a pawl device arranged to oppose the transmission of movement in the first direction of rotation, in that the control unit is connected to a pawl declutching member for declutching the pawl and enabling movement to be transmitted in the first direction of rotation, in that the transmission includes, downstream from the pawl device, a member for transforming rotary movement into movement in translation of a slide connected by a connecting rod to an eccentric portion constrained to move in rotation with the movable flight control surface, and wherein the motor, an adjacent portion of the transmission as far as the slide, the pawl device, and the declutching member are mounted on a strength member connected to a stationary structure by a hinge.
