- 摘要:
- 针对四氧化二氮(NTO)的特殊氧化性，筛选了三种不同胶凝剂与NTO形成凝 胶．对其流交性能进行研究。并结合发动机试验、限流圈试验、发动机头部液流试验，验证 了其与偏二甲肼(UDMH)凝胶组成的双组元推进剂用于凝胶发动机试验的可行性。结果表 明：单一胶凝剂和NTO形成的凝胶体系不能满足凝胶发动机的要求，而复合胶凝剂YN61+ YN71与NTO形成的凝胶体系具有粘度高、所需剪切力低的优异流变性能，基本能满足凝胶 发动机的要求。
- Abstract:
- Aiming at the special oxidizability of NTO，three different gellants were chosen which could form gel with NTO，and their rheologic properties were studied．By means of rocket motor test， restriction orifice test and fluid flow test of rocket engine head，the feasibilities that NTO gel could constitute gelled bipropellant with UDMH gel were testified．It shows that，single gel system call not meet the requirement of gelled propellant rocket engine design，however composite gel system has excellent theologic property of higll viscosity and low shearing strength can meet the requirement of gelled propellant of rocket engine．
