A method based on linearized theory is presented for calculating the theoretical suction force at the subsonic leading edges of a family of wings at supersonic speeds. The method is used to determine the optimum sweepback angles for the tips of trapezoidal wings and to determine the effect of curvature of the tip contour on the lift-drag ratio of wing regions influenced by the tip.
