On the Problem of Shaping an Axisymmetric Body to Obtain Low Drag at Large Reynolds Numbers

Abstract

This report describes efforts in the analytic design of an axisymmetric body having low drag with a fully turbulent boundary layer in compressible flow. Drag is to be made small by proper shaping of the body. Several theoretical studies of various types are reported in the attempt to determine what body shapes have low drag. The principal conclusion is that the drag coefficient is not very sensitive to body shape.
