摘要
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。
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.
