摘　　要：研究了硝酸羟胺水溶液凝胶化的工艺过程并通过密闭爆发器实验评价了不同水含量凝胶体的燃烧性能。结果表明,此种工艺制备的含水量为34.92%的硝酸羟胺(HAN)凝胶体能量可达757.58J·g-1,燃烧时间少于52.30ms,可广泛应用于固体推进剂系统及安全制动系统中。The preparation of hydroxylammonium nitrate (HAN) hydrogel was introduced and related properties of the gel was characterized. Based on the closed bomb test,the combustion characteristics of the gel with different water contained were studied. The energy of the gel with the water content 34.92% can reach 757.58 J·g^(-1),and the burn time less than 52.30 ms. The hydrogel can be applied to solid propellant system and the safety brake system.
