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. |
