红烟硝酸/偏二甲肼凝胶双组元推进剂研制

Research and Manufacture of Red Fuming Nitric Acid/ UDMH Gel Bipropellant

针对红烟硝酸/偏二甲肼的化学性质,结合流变性能测试、发动机头部液流实验、限流圈实验及地面热试车,筛选出合适的胶凝剂。其与红烟硝酸/偏二甲肼形成具有优异流变性能的凝胶体系,且该体系在热试车中表现良好,基本能满足凝胶发动机的要求。

Aiming at the chemical properties of red fuming nitric acid / UDMH, by means of rheological properties test, fluid flow test of rocket motor head, restriction orifice test and ground hot firing test, the appropriate gellant was screened out. It can form gel system with red fuming nitric acid / UDMH. The gel system possesses excellent rheological properties and good behaviour in hot firing test, it can basically satisfy the requirement of gel motor.
