摘要： A device for regulating the setting angle of a control surface such as a flap or rudder on an aircraft comprising an inflatable bag located between the control surface and the fuselage. Air for inflating the bag is drawn from outside the aircraft at a location where increased pressure due to dynamic pressure of the passing airstream is available. The control surface and the bag may be provided with coinciding openings therein, and a secondary flap is mounted on the control surface immediately behind said openings as viewed in the direction of the airstream. The secondary flap when raised from the control surface creates a pressure rise at the openings, thus pressurizing the openings and thereby also the interior of the bag leading to actuation of the main control surface in servo fashion.
