Abstract
This invention relates to a system for controlling an aerodynamic surface mounted mobile on an aircraft so as to be able to pivot freely about a fixed axis and provided with a tab itself articulated on the trailing edge of the aerodynamic surface, the system being such that elastic connecting devices are provided between the tab and the aerodynamic surface and the tab can be directly actuated by the pilot, via a voluntary actuating member and a mechanical linkage. According to the invention, this system comprises: an actuator interposed between the elastic connecting device and the aerodynamic surface; a device for controlling the actuator; and a clutch connecting the structure of the aircraft to the mechanical linkage; and the device for controlling the actuator also controls the clutch, so that the latter is in disengaged position when the actuator is active and in engaged position when the actuator is inactive.
