An improvement to the controllability of aircraft wherein vortex generators are connected to a control surface in front of the hinge line of the control surface so that when the control surface is deflected, the vortex generators project into the airstream on the opposite side from the deflecting control surface. The action of the vortex generators causes the airflow to remain attached to the control surface at higher angles of attack than would otherwise be possible thus increasing the lift of the airfoil and control surface.
A control surface for generating force due to a medium flowing thereover having a leading portion with opposite side surfaces and a trailing portion movable with respect thereto, the improvement comprising: movable means for generating vortexes in the flowing medium adjacent the trailing portion, said movable means comprising a plurality of blades of airfoil cross section projecting into the flowing medium, said blades having chord lines inclined relative to the flowing medium to generate vortexes therefrom; means to extend and retract said movable means...
