本文采用惩罚函数法(SVMT 调用 BFGS 法)对单室双推力固体火箭发动机进行了最优化设计。设计中以发动机的最小重冲比为目标函数,以战术技术要求、结构强度、工艺限制等为约束条件;设计变量为装药几何及内弹道性能等10个参数。程序在 TO—16机上运行并获得成功。本文提供了相应的算例。
In this paper, the penalty function method (SVMT call BFGS method) to optimize the design of single-chamber double-thrust solid rocket motor. In the design, the minimum recoil ratio of the engine is taken as the objective function, and the requirements of tactics, structural strength and process constraints are used as constraints; the design variables are 10 parameters such as the charge geometry and the internal ballistic performance. The program runs on the TO-16 machine and succeeds. This article provides the corresponding examples.
