A Waverider Design Method Based on Given Shapes of Shock and Lower Surface
A waverider design method based on given shapes of shock and lower surface is presented according to osculating cone method. In this method, streamlines from the given curve of lower surface could be captured to generate lower surface. The intersection curve of shock envelope and lower surface is treated as the leading edge of the waverider. Upper surface could be generated by free streamlines from the leading edge or other technique requirements. Two waverider configurations are obtained by this method, whose trailing edges of lower face are a u-type curve and a straight line respectively. Their waverider characteristics are verified by CFD codes solving Euler equation and NS equation to validate the reliability of this waverider design method. The main advantage of this method is that designs of lower surface and upper surface are separated. Directly variation of lower surface shape can be convenient for designing thermal protection system, satisfying engine requirements or improving transverse stability. Increasing the distance between shock and lower surface could increase the height of middle part and the length of whole vehicle, which is beneficial for optimization design.
