Natural-Flow Wing

Abstract

Novel scheme developed to contour three-dimensional upper and lower surfaces of wing independently to take maximum advantage of naturally occurring flow and resultant distribution of pressure over broad mach number and lift range. Scheme contours lower and upper surfaces at given cross section to optimize local slopes of upper surface. Sections sheared vertically to create reflexed lower surface. Creates wing nearly flat with mild cumber and minimal twist. Results in design efficient over wide range of lift conditions. Wings for supersonic flight able to provide improved performance at lower speeds without resorting to heavy, complex, and expensive variable-camber devices. Ramifications for both transportation and military systems.
