|Abstract The design method and basic aerodynamic characteristics were studied for cone-derived waverider at Mach 6 and attack angle 0. Off-design performances of the designed waverider were also discussed, namely lift, drag and lift-drag-ratio changing with Mach number and attack angle. All the research works were finished by numerical simulation method. Results show that: the inverse-design method for the waverider configuration is successful 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.
