摘　　要：为考察六氯环三磷腈（HCCT）作为降速剂对RDX-CMDB推进剂燃速、安定性、爆热、机械感度、力学性能的影响,测试了HCCT与RDX-CMDB主要组分的相容性,并采用靶线法、甲基紫法、绝热法等测试了3种不同HCCT含量的RDX-CMDB推进剂的性能。结果表明,HCCT与RDX-CMDB推进剂主要组分NC＋NG及RDX的相容性较好,HCCT的加入使推进剂在2-6MPa压强下燃速降低,燃速压强指数升高,爆热降低,摩擦感度和撞击感度降低,抗拉强度及延伸率基本不变,对推进剂的化学安定性没有影响。In order to investigate the effects of hexachlorocyclotriphosphazene （HCCT） as reducing rate agent on the burning rate, chemical stability, heat of detonation, mechanical sensitivity and mechanical properties of RDX-CMDB propellant, the compatibility of HCCT with the main components of RDX-CMDB propellant was tested and the per-formances of three kinds of RDX-CMDB propellants with different contents of HCCT were measured by target line method, methyl violet test, adiabatic method, etc. The results show that HCCT has good compatibility with the main components NC＋NG and RDX of RDX-CMDB propellant,the addition of HCCT makes the burning rate of the propellant at the pressure of 2 - 6 MPa decrease and the burning rate pressure exponent increase, the heat of detonation, fraction sensitivity and impact sensitivity all decrease, the tensile strength and elongation rate remain basically unchanged, and it has no effect on the chemical stability of the propellant.
