Based on the design of osculating cone waverider, the concept of double swept waverider is proposed. The relationships between design parameters and configuration parameters are derived. Employing the non-uniform rational B-spline (NURBS) to represent the design curve including circular arc and straight line to aid the waverider generating, this paper develops the method for creating the waverider with controllable configuration parameters, including the blunt head area, the sweep angle and the swept area. The computational fluid dynamics technology is applied to validate the effect of the design method, and the advantageous performances of the waverider are also studied. Results show that with appropriate configuration, the waverider has advantageous performances in subsonic characteristics, aerodynamic stability and nonlinear vortex lift, while maintaining the high hypersonic performance. The method provides a novel way to design the wide-velocity-range hypersonic vehicles.
Key words： waverider; double swept; subsonic characteristics; stability; vortex lift
