火箭发动机燃烧室压力测试中引压管设计

Primary exploration of press-leading tube design in rocket chamber-pressure test

利用管道固有频率计算的基本原理,较为深入地研究了压力测试中引压管固有频率与管内充质、结构之间的关系;根据传热学基本原理,对引压管进行了传热类型分析,并利用有限元方法,分析了管内充质为水时引压管的热传导特性。所得结论为小推力液体火箭发动机燃烧室压力测试中的引压管设计提供了参考依据。

According to the keystone of tube inherent frequency computation,it was deeply studied for the relationship between inherent frequency of press-leading tube and the substance in it and its structure.Based on heat-transfer theory,the heat transfer style of press-leading tube was analyzed.By the means of finite elements,it was studied for the heat conduct characteristic of press-leading tube when the substance in it was water.The results offered reference frame for the application design of press-leading tube...
