The subject invention relates to a new and improved airfoil design. More particularly, an airfoil design is disclosed which improves efficiency by taking advantage of the vortex created at the wing tips.
An improved wing design for an aircraft, said wing having opposite ends separated from each other in a span-wise direction, with said wing generating trailing vortices at said opposite ends with the vortices turning in opposite spirals, said improvement comprising: a pair of structural airfoils means on said opposite wing ends, with each said airfoil means having cambered surface area extending in the spiral directions of the vortices and aerodynamically coupled together with increasing dihedral angle in the flow direction, progressive changing angles of...
