초록

A novel set of serrated-planform lifting surfaces produce unexpectedly high lift coefficients at moderate to high angles-of-attack. Each serration, or tooth, is designed to shed a vortex. The interaction of the vortices greatly enhances the lifting capability over an extremely large operating range. Variations of the invention use serrated-planform lifting surfaces in planes different than that of a primary lifting surface. In an alternate embodiment, the individual teeth are controllably retractable and deployable to provide for active control of the vo...

청구항

[ We claim:] [1.] An aerodynamic lifting device disposed upstream of a primary lifting surface; said aerodynamic lifting device comprising a plurality of teeth arranged essentially in tandem, each of said teeth being individually disposed in a plane that intersects said primary lifting surface.
