The renewed interest in the design concepts for both the high-speed civil transport (HSCT) and space launchers, including reusable launch vehicles (RLV) and low-Earth-orbit (LEG) satellite launchers, may mark the beginning of a new era of advanced vehicles. Practical inverse design methods are needed for the speed range of these vehicles. Inverse solution existence and uniqueness issues are discussed for supersonic and hypersonic three-dimensional inverse procedures that use space-marching techniques. By using extreme body-slope angle, a simple method to estimate the limiting domain of inverse solution existence is proposed and applied to several example test cases with and without angle of attack. The method provides useful information about possible target pressure distributions and inverse solution existence without performing any inverse calculations. By investigating the relations between the surface pressure and the body geometry, a general explanation for inverse solution uniqueness has been described. Sample calculations to support this explanation are presented.
