为优化无喷管固体火箭发动机的设计资源,文中围绕装药参数对无喷管固体火箭发动机性能的影响展开分析与计算。计算结果表明:装药能量、装药燃烧特性、装药结构参数对无喷管固体火箭发动机性能有不同的影响,无喷管发动机设计中采用高能装药、高燃速装药、优化装药结构、合适的装药燃速压强指数、两种燃速装药串联对于无喷管发动机性能的提高有利。

In order to utilize the nozzleless design resource effectively, the nozzleless rocket motor' performance was analyzed by u-sing different grain. The results indicate that different grain has different effect on the performance. The nozzleless motor design adopts grain with high energy and burning rate, grain structure optimization, proper grain burning rate pressure index, the tandem of two kinds of charge with different burning rate is good for performance improvement of nozzleless motor.
