摘　　要：在综合考虑固体火箭发动机设计、轨道设计和总体特性相互作用、相互影响的情况下,建立了捆绑助推器总体/动力/轨道一体化设计优化模型和系统分析模型,并应用遗传算法完成了某大型捆绑助推器6个设计参数的优选。结果表明:本文方法优化设计效果明显,优化所得助推器质量比原方案减轻了17.7%。Considering the mutually interacting phenomenon of such aspects as trajectory, solid rocket motor and system, a set of mathematical analytical models for the design and optimization of rocket were developed. An optimizing calculation with 6 design parameters for the rocket was made by using genetic algorithm. It shows that the optimized concept reduced 17.7% of the booster mass of the primary, indicating that the optimized results are satisfactory.
