摘要

Waveriders have been proposed for various aerospace roles, including spaceplanes and supersonic/hypersonic cruise vehicles. Conical flowfields are frequently used in the design of waveriders; however, due to the inverse design requirements the use of non-conical flows is also possible. In this research, the flows around cones and blunt-bodies are obtained by solving the two-dimensional axisymmetric Euler equations using an implicit TVD scheme; these results are then used to generate waverider designs. The aerodynamic characteristics are calculated by integrating the pressure over the waverider surface, and skin friction is estimated using the reference temperature method. Validation of the use of CFD in waverider design is performed, and optimized designs generated from conical and blunt-body flows are compared based on vehicle geometry and performance characteristics.
