摘　　要：以固定式收敛喷管的设计为例,在研究了喷管外形设计的参数化描述基础上,应用VB环境下CATIA二次开发的自动化技术,实现了喷管外形参数化设计。实例表明,所提出的方法能快速生成喷管外形,可以实现喷管外形参数化设计。The parametric design of the configuration of fixed convergence nozzle is used as a test example. The parametric representation of the nozzle configuration is investigated. The parametric design of the nozzle configuration is implemented by making use of the API technique of CATIA. The test example shows that the approach presented is able to generate a three dimensional shape of nozzle and meet the need of the parametric design of nozzle configuration.
