摘 要:传统固定构型乘波体飞行器难以在宽速域飞行剖面保持最佳性能。为此,开展了变体高超声速乘波体飞行器构型设计优化技术的研究,构建了变体飞行器构型设计优化框架。提出了考虑边缘变形的变体乘波体构型类函数/形函数变换(CST)参数化方法;根据兼顾气动力、热、射程的变体收益评估模型,采用基于Kriging代理模型的约束差分进化算法求解多个工况下的最优构型。对比基准固定构型,以最优构型变体飞行能够显著改善飞行器宽速域飞行性能,升阻比平均提升4.82%,再入弹道增程4.13%,验证了变体构型优化技术的有效性,其对高超声速变体飞行器设计、研制具有参考价值。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-aerothermodynamicstrajectory 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.
