Theoretical Pressure Distributions for Some Slender Wing-Body Combination at Zero Lift

Abstract

Pressure distributions are calculated for some asymmetrical wing-body combinations at zero lift. The theory of the calculations is based on the assumption of extremely slender wings and bodies and yields results for both subsonic and supersonic speeds. The examples considered are swept wings of constant chord mounted on bodies of nearly cylindrical form. Of particular interest is the effect of indenting the body on the distribution of pressure over the wing. When the indentation is such as to maintain a constant total area of the cross sections normal to the stream, the theoretical pressure disturbances remain small throughout the transonic range. With such indentation the isobars tend to remain smooth and nearly parallel to the sweep of the wing surface.
