Abstract

Multistage waverider vehicles based on the combined trajectory flight possess aerodynamic performance advantages, offer more flexible trajectories, and can achieve extended ranges. However, current multistage waverider design technology remains underdeveloped and is still in the preliminary theoretical research stage. This paper extends the design methodology for two-stage waverider vehicles, enabling the design of a first-stage wide-speed-range waverider that conforms to the leading edge of a given irregular second-stage airbreathing lifting-body configuration, thus forming a two-stage waverider structure. According to the specific optimization requirements, we refined the multi-fidelity data-mining-based MDO (Multidisciplinary Design Optimization) framework, yielding an optimized first-stage wide-speed-range lifting body configuration with superior performance under viscous conditions. Compared with the initial configuration, the optimized first-stage vehicle, with a constant takeoff mass, achieved a 5.84 % increase in range for the boost-glide combined trajectory, further verifying the effectiveness and flexibility of the multi-fidelity data-mining-based MDO framework.
