A system and method for dissipating vortices that form at the wingtips on aircraft and from other airfoils. A jet air stream is discharged in a location at or proximate to the outer end portion of the airfoil into the vortex flow, and the jet air stream is moved cyclically back and forth. The cyclic movement can be at lower or higher frequencies to alleviate at least in part intensity of the vortex or accelerate instability of the vortex which leads to vortex dissipation.
We claim: 1. An airfoil vortex dissipating system comprising: a) an airfoil having a leading edge, a trailing edge, an outer end portion, an upper aerodynamic surface, a lower aerodynamic surface, a spanwise axis, a forward to rear chord axis, and an alignment reference plane coincident with the spanwise axis and the chord axis, said airfoil being characterized in that when the airfoil is functioning to create aerodynamic lift, a vortex is created at said outer end portion of the airfoil, with said vortex having vortex core axis, a main circumferential ...
