Reduction of wave drag of wing-body combinations at supersonic speeds through body distortions

William C. Pitts

Abstract

Report presenting some methods providing sizable reductions in drag for aspect ratios of current interest. The drag savings are maintained over a wide Mach number range, particularly for low-aspect-ratio wings. A significant part of the drag reduction is found to be due to the nonaxisymmetric distortion.
