Aerodynamic heating numerical simulation method research for quasi-waverider hypersonic vehicle

The aeroheating problem of quasi-waverider hypersonic vehicle with air-breathing engine and high speed is quite serious. It is a key problem how to predict the aerodynamic heating and decrease the body temperature. This paper presents a solution taken in three-dimension N-S equation and MacCormack central scheme. The simulation results indicate that the numerical algorithms proposed in this paper provides remarkable improvements comparing with classic and mature engineering prediction methods. The prediction accuracy is greatly enhanced, together with the possibility as a consult for heating prevention system design.
