Abstract : A method for the determination of the flow field about any axially symmetric body shape for any conditions of hypersonic flow is described. The method involves the combination of streamtubes in the field and obtains a solution of the complete field by an iteration process starting with initial guesses for the body pressure distribution and the shock shape and location. This technique has been successfully applied to the solution of the flow field about axially symmetric bodies with ideal or equilibrium gases including bodies with slope discontinuities where no secondary shocks exist in flow. The complete flow field solution is obtained given only the body shape and size and the free stream conditions. The results of a flow field about a spherically blunted cone are presented for M = 20, h = 200,000 ft. altitude using an 11 species, 13 reaction model of air. Comparison is made with the equilibrium air solution for the same conditions. (Author)
