硝酸铵基推进剂的能量计算与分析

采用最小自由能法计算了含有氧化剂HNIW、AP和HMX及粘合剂BAMO、GAP、PET和HTPB等成分的硝酸铵（AN）基推进剂的能量特性参数，分析了上述成分对AN推进剂能量的影响。结果表明，高能化合物HNIW并不是在任何含量的粘合剂条件下提高AN基推进剂能量的幅度均高于其它氧化剂。当粘合剂含量为15％，HNIW提高推进剂能量的幅度大于HMX小于AP；粘合剂含量为5％时，HNIW提高推进剂能量幅度高于其它两种氧化剂。在低含量（〈12％）的粘合剂体系中，使用惰性粘合剂有利于提高推进剂的能量；在粘合剂含量较高（〉13％）的体系中，含能粘合剂提高能量的幅度优于惰性粘合剂，且GAP优于BAMO，每种粘合剂都有一最佳用量。

Calculation and Analysis on Energy Characteristics of AN-based Propellants

The effect of oxidizers (HNIW, AP and HMX) and binders (BAMO, GAP, PET and HTPB) on energy characteristics of the AN-based propellants is investigated by the least free energy method. Results show that high energy compound HNIW to increase energy level of the AN-based propellants is always not higher than that of other two oxidizers. The amplitude of HNIW to increase the specific impulse of the AN-based propellants is higher than that of HMX, and less than that of AP when the content of binder is equal to 15%,however the amplitude of HNIW to increase the specific impulse of the AN-based propellants is higher than that of HMX and AP when the content of binder is equal to 5%. Non-energetic binders benefit increasing energy of the AN-based propellants in lower content (<12%)binder system, but energetic binders benefit increasing energy of the AN-based propellants in higher content(>13%)binder system. GAP is more beneficial to increasing energy better than BAMO, and every binder all exists a optimum addition amount.
