Method and apparatus for generating a stable leading-edge lifting-vortex controller

摘要

Method and apparatus for generating a stable leading edge lifting vortex controller that significantly improves flight control and safety of an aircraft. More specifically, in a preferred embodiment, the present invention is generally a triangular or diamond-shaped member, as seen in a plan view, having a leading edge and a trailing edge wherein the trailing edge of the member is attached to the leading edge of an aircraft wing in substantially the same plane as the wing. The distal end of the leading edge of the member has a slightly drooped rounded nose. The member has a variable thickness wherein the upper surface of the member has a camber and wherein the member is substantially shaped like an airfoil. The thickness at the centerline of the member proximal to the wing is approximately the thickness of the leading edge of the wing to provide a smooth transition along the centerline. The thickness decreases from the centerline to the two distal opposing edges from the centerline that contact the leading edge of the wing to form a sharp point having negligible thickness. As air travels over the leading edges of the member, a lifting vortex is generated on each side of the member. These vortices travel on the low pressure side of the wing generally in an aft direction thus mixing high-energy airflow with the slower air within the boundary layer thereby reducing boundary layer separation along the wing.
