The analysis of the possibility of using the numerical approximation schemes streams Roe FDS and AUSM + to meet the challenges of hypersonic aerodynamics and research trends in the perturbed region ahead streamlined blunt body to determine the laws of thermal and gas-dynamic processes and the establishment of the characteristics associated with the development of the necessary thermal protection of aircraft. Based on a comparison of the data with the experimental results revealed that the method of splitting the flow AUSM + is able to solve the problem of hypersonic flow around bodies with acceptable accuracy.
