A SPECIAL METHOD FOR FINDING BODY DISTORTIONS THAT REDUCE THE WAVE DRAG OF WING AND BODY COMBINATIONS AT SUPERSONIC SPEEDS

摘要

For a given wing and supersonic Mach number the problem of shaping an adjoining fuselage so that the combination will have a low ware dray is considered. Only fuselages that can be simulated by singularities (multipoles) distributed along the body axis are studied. However, the optimum variations of such singularities are completely specified in terms of the given wing geometry. An application is made to an elliptic wing haring a biconvex section, a thickness-chord ratio equal to 0.05 at the root, and an aspect ratio equal to 3. A comparison of the theoretical results with a wind-tunnel experiment is also presented.
