Analytic results from inviscid hypersonic small-disturbance theory for non-axisymmetric conical flow past a nearly circular cone are used, and results are valid for all values of K(, (delta)) = M(, (INFIN))(delta), where (delta) is the semi-vertex angle of the basic circular cone. The special case of the configurations generated from axisymmetric conical flow is compared extensively with other configurations to give insight on the effects of the pertinent parameters. The inviscid analysis accounts for wave drag only, but the effect of viscous drag is discussed. The results are analytic in nature and particularly suitable for studying the various trade-offs that are involved in missile design. Comparison of the results with other types of lifting bodies suggest that properly selected waveriders are among the best producers of large lift-to-drag ratios.xiii, 109 leaves :Engineering, Aerospace.Thesis
