摘　　要：为提高弹道导弹概念设计中各学科的协同效应,缩短概念方案研制周期,以设计出综合性能更好、效能更高的飞行器方案,以iSIGHT为集成与优化平台,建立了多学科设计优化弹道导弹概念设计系统,综合弹道导弹概念设计各个学科的知识,应用有效的设计/优化策略,来组织和管理弹道导弹概念设计过程。将混合优化策略应用于弹道导弹重量、弹道和动力一体化优化设计,很好地解决了各学科间复杂耦合带来的计算问题,给出了方案优化结果,证实了该算法的有效性。To improve collaboration among different disciplinary in the conceptual design of ballistic missiles, to shorten development cycle of conceptual scheme and obtain conceptual scheme with better integrated performance, knowledge of each disciplinary was integrated and proper optimization strategy was selected to manage the process of ballistic missile conceptual design based on a conceptual design system developed on iSIGHT integration and optimization platform. Hybrid optimal strategy was applied in conceptual design of ballistic missile with three disciplinary, namely weight disciplinary, propulsion disciplinary and trajectory disciplinary, as a result the calculation problems caused by coupling relationship between disciplinary were well solved. Optimization results were provided, as well as the validity of the optimization algorithm was also proved.
