Abstract: Improvement to a fixed-wing airborne vehicle which results in significant delay drag rise well into the transonic regime. The fundamental features of the improvement include: fixedly skewing the wings at 45 degrees; shaping the outboard ends of the wing tips so that the trailing edge of the forwardly disposed wing is swept forwardly and the leading edge is straight relative to the trailing edge, and so that the leading edge of the rearwardly disposed wing is swept rearwardly and the trailing edge is straight relative to the leading edge; and, blending the leading and the trailing edges of the planform, so as to increase the local chord and control the longitudinal position of the maximum thickness in the root area (i.e., at the interface of the inboard tip end of each wing with the fuselage).
