Abstract
The fixed-configuration waverider often fails to deliver optimal performance across a wide range of flight speeds. Research is conducted on the configuration design optimization of a morphing hypersonic waverider vehicle. Initially，the corresponding optimization framework for the morphing vehicle is established. A class function/shape function transformation（CST）parameterization method for the morphing waverider configuration，which accounts for leading edge variation，is proposed. Subsequently，the Kriging-assisted constrained differential evolution algorithm is employed to efficiently determine the optimal waverider configuration under various conditions，based on an aerodynamics-aerothermodynamics-trajectory morphing assessment model. Compared to the initial fixed configuration，the morphing strategy utilizing optimal configurations significantly enhances wide-speed range flight performance. On average，the lift-to-drag ratio is increased by 4. 82%，and the range is improved by 4. 13%. These results demonstrate the effectiveness of the morphing configuration optimization and offer valuable insights for the design of hypersonic morphing aircraft.
