摘　　要：为研究含二硝酰胺铵（ADN）推进剂的能量、安全、贮存及燃烧性能，根据最小自由能原理计算了含ADN推进剂的能量特性参数，采用密闭爆发器及靶线法测试其爆热及燃速，并对其吸湿性及感度进行了研究。结果表明，含ADN／A1／HMX、ADN／A1／CL20、ADN／A1H。／HMX和ADN／A1H。／CL20推进剂的标准理论比冲分别为2675～2685、2677-2686、2801～2810和2803-2812N·s·kg^1，采用硝酸酯增塑的惰性聚醚黏合剂体系可制备出固化正常、结构致密的含ADN推进剂。随着推进剂配方中ADN含量的增加，推进剂的爆热、吸湿性、燃速和压强指数增大，摩擦感度和撞击撞击提高，密度略有降低。In order to study the energy,safety,storage and combustion performances of propellants containing ammonium dinitramide (ADN),the energy characteristic parameters were calculated based on the minmum free energy mechanism.The heat of detonation and burning rate were tested by closed bomb test and target line method, and the moisture absorption and sensitivity were studied.The results show that the standard theory specific impulses of propellants containing ADN/Al/HMX,ADN/Al/CL-20,ADN/AlH3/HMX and ADN/AlH3/CL-20 are in the range of 2 675 -2 685,2 677 -2 686,2 801 -2 810 and 2 803 -2 812 N ·s ·kg-1 ,respectively.ADN propellant with normal curing and compact structure can be prepared using the inert polyether binder system plasti-cized by nitrate ester.With increasing the content of ADN in the propellant formulation,the heat of detonation, moisture absorption,burning rate and pressure exponent of the propellant increase,the friction and impact sensitivities of the propellant increase and the density decreases slightly.
