Abstract : The report determines the effects of air dissociation upon the heat transfer to and the re-entry performance of a solid, non-melting, long range ballistic missile re-entry body. Since such bodies re-enter the atmosphere at velocities of the order of magnitude of 20,000 ft/sec it is apparent that considerable heat can be generated by the nose shockwave and by viscous work in the boundary layer air surrounding the body. First order studies have estimated heat transfer characteristics using perfect gas relations. It is the purpose of this study to assess the possible error accruing due to such assumptions. (Author)
