| 摘 要： | 对UDMH/NTO(偏二甲肼/四氧化二氮)双组元推进剂凝胶剂进行筛选的基础上,分别制备了UDMH与NTO凝胶推进剂,利用Brookfield流变仪研究了其流变性能;在进行了初步发动机试验后发现,氧化剂凝胶的无机凝胶剂颗粒会堵塞管路而使试验不能正常进行。通过对氧化剂凝胶的改进,重新建立了氧化剂凝胶体系并研究了其流变性能。发动机试验表明:新的UDMH/NTO双组元凝胶体系能够满足发动机设计对凝胶推进剂的要求。

| Abstract: | The gellant of UDMH/NTO bipropellant was selected. UDMH and NTO gel was prepared and its rheologic property was studied with Brookfield rheometer. At the time of primary rocket motor test, we found that rocket motor test could not normally go on because of inorganic granule of oxidant gel. By ameliorating oxidant gel, we rebuild oxidant gel system and further studied its rheologic property. Rocket motor test shows that the new UDMH/NTO bipropellant can satisfy the requirement of gel propellant of rocket motor design. |
