目前固体火箭发动机的设计程序多种多样，对发动机的分析与设计侧重各不相同。本文叙述的分析方法并非要代替现有的设计程序，而是让设计师在设计的初级阶段，在微机上就可完成有意义的工作．在承包商极少参与的研究阶段，本文所介绍的方法能够对固体火箭发动机的结构尺寸和灵敏度进行预估与分析。在交互式图形显示的环境中，本文描述的模型可提供发动机的重量、尺寸和布局等数据． The current solid rocket engine design process varied, focusing on the engine analysis and design vary. The analysis method described in this article is not intended to replace the existing design process, but to enable designers to do meaningful work on the PC in the initial stages of design. In the research stage where the contractor is seldom involved, the method presented in this paper can predict and analyze the structural size and sensitivity of the solid rocket motor. In an interactive graphical display environment, the model described in this article provides data on the weight, size, and layout of the engine.
