本文研究的数值计算方法,用以确定固体火箭推进剂系统的最佳配比,其比冲最高。根据对最优化理论的分析,本文采用直接搜索法结合计算机程序 CEC71(一种热力计算程序)[6],以获得固体推进剂在冻结流或平衡流条件下的最优配比。比较了计算结果和文献报导的数据,可看出直接搜索法用于确定固体推进剂系统的最优配比是有效的。
The numerical calculation method studied in this paper is used to determine the optimal ratio of solid rocket propellant system with the highest specific impulse. According to the analysis of the optimization theory, we use the direct search method combined with the computer program CEC71 (a kind of thermal calculation program) [6] to obtain the optimal ratio of solid propellant in the frozen or balanced flow conditions. Comparing the calculation results with the data reported in the literature, it can be seen that the direct search method is effective in determining the optimal ratio of solid propellant system.
