为实现含能材料1，1\'二羟基‑5，5联四唑二羟胺盐（TKX‑50，又名HATO）在固体推进剂领域的高效应用，运用最小自由能法计算了含TKX‑50、CL‑20、TKX‑50/CL‑20的聚叠氨缩水甘油醚（GAP）基固体推进剂能量性能，分析了TKX‑50和CL‑20复配应用的可行性，预估了TKX‑50/CL‑20复配推进剂应用效能。结果表明，TKX‑50含量增加时，燃烧室中推进剂平均温度（Tc）和燃气平均相对分子质量（M¯g）同时下降，理论比冲呈先升后降的变化规律；TKX‑50与CL‑20相容等级为B，TKX‑50/CL‑20复配推进剂热稳定性和安全性能良好；TKX‑50/CL‑20复配推进剂可大幅拓宽配方各组分含量选择范围，理论比冲大于272 s的推进剂中CL‑20含量下限仅为纯CL‑20推进剂的40%；相同能量水平下，TKX‑50/CL‑20复配推进剂表现出低成本和低特征信号的特点，具备工程推广应用的潜力。“,”In order to realize the efficient application of TKX‑50 in field of solid propellants， the energy performance of poly（glycidylaminopropyl ether） （GAP）‑based solid propellants containing TKX‑50， CL‑20， and TKX‑50/CL‑20 was calculated using the minimum free energy method， and the feasibility of TKX‑50 and CL‑20 combination application was analyzed. The application efficiency of TKX‑50/CL‑20/GAP‑based solid propellant was also estimated. The results show that when TKX‑50 content increases， balance combustion temperature of propellant in combustion chamber（Tc） and combustion gas average relative molecular mass（M¯g） of propellant decrease at the same time， and the theoretical ratio of impulse was first increased and then decreased. The compatibility of TKX‑50 and CL‑20 was moderate compatibility. It has good thermal stability and safety performance of the TKX‑50/CL‑20 mixture propellant. It can significantly broaden the choice of the content of each component of the formulation with TKX‑50/CL‑20 mixture propellant. The lower limit of CL‑20 content in the compound propellant with theoretical specific impulse greater than 272 s was only 40% of pure CL‑20 propellant. At the same energy level， TKX‑50/CL‑20 mixture has the characteristics of low cost and low characteristic signal， and has the potential of engineering application.
