Abstract
Embodiments of the present airfoil systems comprise an airfoil with a leading edge, a trailing edge, an upper surface, a lower surface, and a skin surface, at least one structural element located within said airfoil, wherein said structural element supports the skin surface having an upper skin portion and a lower skin portion wherein said structural element can change its shape in response to external stimulus during flight operations, and an actuating means for selectively altering the curvature of said structural element which alters the curvature of said upper skin portion and of said lower skin portion to cause nonlinear deflection of said skin surface between an extreme raised position through a neutral position to an extreme lowered position; whereby the outer surface curvature of said airfoil and said skin surface is smooth and continuous over substantially the entirety thereof at all positions of said skin surface.
