Abstract
Abstract : Hypersonic viscous flow about slender cones, wedges, and 3/4 power law bodies is considered. Body thickness ratios leading to minimum drag are determined subject to constraints of fixed base, fixed volume, or fixed surface area. It is assumed that the shocks are strong and that the fluid is ideal. It is found that minimum drag occurs in a flow region where viscous interaction and, for axisymmetric bodies, transverse curvature must be taken into account. Numerical results are given for optimum thickness ratio and minimum drag as a function of altitude. (Author)
