Vortical lift over a highly swept wing can be controlled by stabilizing or strengthening the major vortex by a small continuous jet of air, or a pulsating jet, near the core of the vortex. This method relies on the natural inductive action of the vortex swirling flow to entrain the injected air into the core of the vortex. When the additional momentum from the blowing air becomes aligned with the vortex mean flow direction, the vortex is stabilized and vortex breakdown is delayed.

[ We claim:] [1.] A controller to enhance or stabilize a vortex created by fluid flowing over a swept wing; said controller comprising a source of pressurized fluid, and at least one aperture in the upper surface of the wing adapted to inject fluid from said source at least partially into the core of the vortex at a selected velocity and in a selected direction; wherein the position, velocity, and direction of the injected fluid enhance or stabilize the vortex.
