This invention is for wings of all types, such as fixed wings for aircraft and hydrofoil boats, and rotary blades (or wings) for helicopters and turbines, to be equipped with a slotted tube, or a tube with series of holes extending outwardly in the spanwise direction near the trailing edge of the wing tip for blowing jets of fluid (such as air or water) in the direction opposite to the lift of the wing, thereby achieving flow in the form of a jet sheet to abate, diffuse and break up the undesirable wing-tip or blade-tip vortices.
Apparatus for abating wing-tip vortices formed at thE tips of a wing when it is in a fluid stream flowing relative to said wing, said vortices being formed as a result of a difference in fluid pressure on one side of the wing relative to the fluid pressure on the opposite side of the wing which causes a rush flow of fluid from the side of higher pressure to the side of lower pressure, said apparatus comprising a wing having at least a pair of wing tips, a source of pressurized fluid, a plurality of jetting means, and means connecting said jetting means t...
