The report discusses the development of a procedure for determining flow properties behind conical and oblique shocks which has a short computation time. This was accomplished by curve fitting shock properties. The necessity of using real gas properties in determining post shock properties is illustrated by comparing the real gas solutions to the perfect gas solutions. In addition the effect of using real versus perfect shock gas properties in determining heat transfer is illustrated by comparing equilibrium skin temperatures computed using the two different post shock property solutions. From this study it was found that though there is considerable difference between real and perfect gas shock properties, this difference is not sufficient to cause large differences in equilibrium surface temperatures.
