战术导弹多学科设计优化

Research on Multidisciplinary Design Optimization of Tactical Missile

建立了战术导弹多学科系统分析模型,提出了战术导弹多学科设计优化方法。通过系统级总体设计优化和并行的子系统级发动机设计优化的嵌套循环,得到满足战术导弹总体设计指标的最优发动机设计方案,即得到内外弹道相匹配的发动机最优推力时间曲线,实现了战术导弹多学科设计优化,缩短了战术导弹总体和固体推进学科的设计周期。战术导弹设计优化时不仅考虑了导弹战技性能指标要求,而且还考虑了22个典型攻击目标的运动特性,增加了导弹最优设计结果的实用性。

The mulfidisoiplinary system analysis models for tactical missile are derived, and the multidisoiplinary design optimization （MDO） methods are established accordingly. MDO methods can gain the optimal design consistent with system design constraints and the solid rocket motor thrust time curve, which is a best match for exterior trajectory by looping execution between system design optimization and parallel subsystem solid rocket motor design optimization, thus the design cycle for tactical missile system and solid rocket motor can be greatly reduced. The tactic-technical specifications, including the motion state of 22 typical targets, are taken into account in the design optimization process of tactical missile.
