摘要
为解决多约束条件下多级火箭的一体化优化问题,减少论证初期方案迭代设计的次数,综合考虑弹道、气动和动力等专业的设计约束,建立了多级火箭的总体/弹道一体化优化模型,运用伪谱法将最优化问题转化为非线性规划问题,求解得到了多级火箭的最优总体参数和最优控制变量。采用的优化方法实现了动态控制参数和静态总体参数的耦合优化设计,为方案阶段火箭总体参数的确定提供了参考。
In order to solve the multi-discipline optimization problem of multi-stage rocket under constraint conditions, and to reduce the number of iterations of the initial scheme of the argumentation, the constraints of ballistics, aerodynamics, engine comprehensively are considered, and an optimization model of multi-stage rocket is established. The pseudo-spectral method is used to transform the optimization problem into a nonlinear programming problem, and the optimal overall parameters and optimal control variables are obtained. The optimization method adopted realizes the coupling optimization design of dynamic control variables and static global parameters, which provide a reference for the determination of the overall parameters of the program phase.
