초록

A jet engine disposed at and preferably in front of the tip end of an airplane wing with exhaust flow intercepting and rotating counter to tip vortex flow to reduce vortex induced drag, the angle of rotation of exhaust flow being cyclically variable to dissipate the vortex flow. The tip engine assists in powering the aircraft.

청구항

In combination with a lift wing of finite length forwardly movable in a fluid medium and having a tip end allowing drag-inducing vortex fluid flow from the higher pressure surface to the lower pressure surface of said wing about an axis extending along the length of said tip end: a housing having a fluid inlet duct and an exhaust opening disposed forwardly of said tip end such that exhaust flow therefrom is discharged in a rearward direction generally parallel to said axis to intercept said vortex; and means associated with said exhaust opening for direc...
