Abstract: This paper extends the concept of the osculating-cone waverider. The global geometrical relationships between the inlet capture curve, flow capture tube and planform contour line are derived to develop the design for the planform-controllable waverider. The vortex effect is introduced by customizing the planform for the waverider. The concept of aerodynamic width-velocity-range design with vortex-shock effects is proposed, meaning employing the vortex effect under subsonic condition and the shock effect under the super/hypersonic condition to ensure a general performance. The CFD technology is used to simulate the aerodynamic performance of the double swept configuration at the subsonic and hypersonic states. A comparison with the flat plate model with respect to the lift, drag and flow characteristics at the subsonic and supersonic states is made. Simulation results show that the planform-controllable waverider has satisfying performance under both subsonic and hypersonic condition, overcoming some deficiencies of the traditional waverider, and providing insight into the width-velocity-range design.

Key words: waverider, planform-controllable, vortex and shock effect, shock wave, width-velocity-range
