An Engineering Prediction Method for Aerodynamic Performance of Waverider with Hypersonic Viscous Interaction

As one of the important physical effects of hypersonic vehicles at high altitude and high Mach number states,hypersonic viscous interaction can have great influence on aerodynamic characteristics of these vehicles.Based on the hypersonic viscous interaction theory and the reference temperature method,a new hypersonic viscous interaction effect considered engineering prediction method for aerodynamic characteristics of the hypersonic waverider is presented in this paper,to overcome shortcomings of some traditional method.At altitudes from 30 km to 70 km and Mach numbers from 15 to 20,through a comparison between the aerodynamic performances predicted by the proposed method,the traditional method the and CFD method,the validation of the proposed method is verified.
