Wind tunnel tests were conducted at a Mach number of 9.45 to determine the aerodynamic characteristics of several conceptual hypersonic aircraft configurations consisting of various half-cone-cylinder bodies and double-delta wings. Effects of body volume, wing planform, and wing-tip deflection on static directional stability were determined. In addition, the effects of wing thickness on the aerodynamic efficiency were obtained. Decreasing body volume, extending the trailing edges, and deflecting the wing tips (toward or away from the fuselage) were all directionally stabilizing. Decreasing wing thickness significantly increased maximum untrimmed lift-to-drag ratios.
