초록

This invention relates to a system and method for reducing the primary vortex wake structure generated by a lifting body mounted on an object moving through a fluid. This is achieved by first, altering the generated initial vortex wake to make it vulnerable to rapid breakup; and, second, producing disturbances to this wake with secondary vortices from auxiliary lifting surfaces, called vortex leveraging tabs, to instigate this breakup. This invention relates to various fields of uses to include vortices generated by any type of lifting body moving throug...

[ We claim:] [32.] A method for reducing the residual effects of a vortex wake structure generated by an aircraft in flight, said method comprising:(a) positioning on the aircraft small auxiliary vortex leveraging tab surfaces (VLTs); and(b) time-varying the effects of the VLTs to thereby introduce wake perturbations to facilitate rapid breakup of the residual effects of the vortex wake structure.
