The maximum lift-drag ratio was used as the optimization target

and a waverider configuration from the conical flow field was designed.To meet the needs of heat protection

a waverider configuration with blunt leading edge was designed.Numerical and experimental methods were used to analyze the aerodynamic characteristics of blunt waverider configurations.The results show that with the blunt radio increasing

the lift of blunt waverider increases 2% and the drag of blunt waverider is nearly 3 times larger than that of the sharp waverider

as well as the ratio of lift to drag of blunt waverider is 50% of that of the sharp waverider. For blunting waverider configurations

the high lift-drag radio characteristics is kept both on and off design conditions.The 2-D inlet was used as the basis

and a waverider/inlet integrated configuration from the muti-wedge-cone flow field was designed.Blunt-leading design was conducted for the integrated configuration.The results from the numerical analysis show that the ratio of lift to drag of this configuration is greater than 2.6

and the total pressure recovery of the inlet is almost 40%

which can meet the requirements of inlet.
