摘要
固体火箭冲压发动机和导弹性能相互之间紧密耦合。从导弹总体方案设计阶段引入一体化设计思想,能充分发挥和协调好固体火箭冲压发动机和导弹的性能,提高了导弹的总体设计水平。采用基于遗传算法、Powell法和模式搜索法的多方法协作优化方法进行了以非壅塞式固体火箭冲压发动机为动力的导弹总体一体化优化设计。算例表明,采用该多方法协作优化方法进行一体化优化设计,可以协调导弹的总体参数,提高导弹的总体性能。
The performance of the solid rocket ramjet and missile influence each other greatly. Integral system project design of missile propelled by unchoked solid rocket ramjet can bring the performance of the solid rocket ramjet and missile into play and make them work in harmony,and improve the performance of the missile and ramjet. Multimethod collaborative optimization algorithm based on genetic algorithm、Powell method and pattern searching method is used to find the best parameters of the system project of the missile propelled by the unchoked rocket ramjet. Using the optimized parameters, the missile can get better system performance.
