摘　　要：采用平衡常数法计算了不同配方下硝酸羟胺(HAN)基水下单元推进剂D1(含二氧杂环己烷)的燃气组成及能量示性数;在液体再生式密闭爆发器中对D1进行了燃烧实验,定性分析了不同装填密度对燃烧性能的影响;对D1、LP1846、OTTOⅡ-三种推进剂的能量特性和水面航迹进行了分析比较。结果表明,D1的理论比冲和特征速度可分别达到2343.53 N.s.kg-1、1466.32 m.s-1,较LP1846(2157.99 N.s.kg-1,1341.04 m.s-1)、OTTO-Ⅱ(2038.52 N.s.kg-1)高;D1水溶性产物占燃气摩尔总数的77.7%,水面航迹较OTTOⅡ-小,具有较好的隐蔽性。The composition of burning gases and energetic properties of hydroxylamine nitrate （HAN） based underwater monopropellants were calculated by balance constant method, D1 with formula of HAN/dioxane/water = 59.15/10.85/30.00 were burned in the liquid regenerative closed bomb,and the effects of different charge densities on combustion properties were analyzed qualitatively. The energetic characteristics and surface wake of D1 propellant were analyzed and compared to that of LP1846 and OTTO-Ⅱ propellant. The results show that the specific impulse and characteristic velocity of D1 propellant come up to 2343.53 N · s · kg^-1 and 1466.32 m · s^-1 respectively,higher than LP1846＇s 2157.99 N · s · kg^-1, 1341.04 m · s^-1 and OTTO-Ⅱ s 2038.52 N · s · kg^-1. Moreover,the water-soluble gas products of D1 propellant come up to 77.7% of the total molar mass of gas products, therefore, the surface wake of D1 propellant is smaller and concealment characteristic is better than that of OTTO-Ⅱ propellant.
