| 摘要: |
| 针对翼柱型药柱固体火箭发动机的结构设计，引入参数化设计方法，把发动机结构的17个关键尺寸定义为可变参数，通过人机交互输入具体的数值，自动完成发动机燃烧室、药柱、喷管等部件的一系列零件图，最终绘制发动机的总体结构图纸。 |

| Abstract: |
| In structural computer Aided Design for bolid Rocket Motors with Finocyl grain-tosketch parametrically engineering drawings, 17 fundamental dimensions of motor structure are definedasvariable parameters, their specific values can be inputted by means of man-machine interaction. Aseries of part drawings of components such as chamber grain and nozzle etc, and the general motorstructure drawing can be sketched automatically. |
