Abstract: Most commonly, a waverider is defined as an aerodynamic configuration that is inversely created from a prescribed hypersonic flow field based on a planar or conical shock wave. In this work, the prescribed shock wave was numerically created from an arbitrary configuration using shock-fitting method. A Shock Generating Body(SGB) was defined as the object to generate 3D flow field with shock wave for waverider creation. The correlation of the longitudinal section, cross section, and leading edge feature between the waverider configuration and its corresponding SGB configuration were analyzed. The analysis results show that the shock wave or expansion wave generated from the aft-body of a double-cone SGB can effectively alter the velocity distribution characteristics of the SGB flow field. This feature can be used to design the longitudinal characteristics of a waverider configuration when its planar profile is restricted. The velocity distribution on cross section can be altered by changing the cross section profile of the SGB, thereby achieving the cross section profile alteration of the generated waverider. A waverider with double-sweep leading edge feature can be generated using a double-cone with expanding aft-body. Qualitative correlations exist between the waverider and the SGB, which provides valuable insight as the guideline to choose appropriate flow field for the design of high performance waveriders.
