Some Theoretical Characteristics of Trapezoidal Wings in Supersonic Flow and a Comparison Several Wing-Flap Combinations
Abstract
A theoretical investigation has been made by means of the linearized theory to determine some of the characteristics of a trapezoidal wing. The lift and pitching moment due to angle of attack and pitching and the lateral force and yawing moment due to rolling were derived. Charts are presented to show the variation of the derivatives, the equations for which are applicable if the inboard Mach line from a leading-edge tip intersects the trailing edge and the outboard Mach line lies ahead of the side edge. Th the case of the wing with raked-in tips, the former condition is sufficient. The trapezoidal wing may, be considered a rectangular wing with a half-delta tip flap (point forward). In view of this consideration, a comparison has been made of this combination with a triangular wing with half-delta and trailing-edge flaps and with a rectangular wing with trailing-edge flaps. The triangular wing with either type of flap offered the most favorable characteristics.
