Design and computational study of waverider configuration with high performance

The design method and basic aerodynamic characteristics were studied by numerical simulation for cone-derived waverider at Mach 6 and attack angle 0. Off-design performance of the designed waverider were discussed, namely lift, drag and lift-drag ratio changing with Mach number and attack angle. The inverse-design method for the waverider configuration is based on inviscid conical shock wave. The biggest lift-drag ratio 3.36 considering viscous effects is obtained at Mach 6 when a proper base conical shock wave angle is chosen. A feasible flight control scheme is presented for the SSTO (single-stage-to-orbit) vehicle adopting this configuration. The favorable method of improving the lift-drag ratio of the figuration is brought forward.
