摘要
针对多任务、可变翼导弹的外形优化设计需求,提出了一种两级优化方法,研究变形弹翼对导弹总质量和飞行性能的影响。在给定的任务和基准方案下,采用遗传算法和模式搜索法混合优化策略,完成了弹翼优化。结果显示,优化后的导弹发射质量和燃料消耗分别减小了5.46%和15.25%。
According to the requirements of the multi-mission missile morphing wing shape optimization design, the influence of morphing wing on the gross weight and flight permance of missile is studied.Given the initial scheme, a hybrid optimization method coupling genetic algorithm and pattern search is chosen to complete the op- timization task. The results show that the gross weight and fuel consumption decrease by 5.46% and 15.25% sepa- rately.
