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 effect of HCCT as a decelerator on the burning rate, stability, detonation, mechanical sensitivity and mechanical properties of RDX-CMDB propellants, the phases of HCCT and RDX-CMDB The properties of RDX-CMDB propellants with three different HCCT contents were tested using the target line method, methyl violet method, and adiabatic method. The results showed that the compatibility of HCCT with RDX-CMDB propellant was better than NC + NG and RDX. The addition of HCCT reduced the burning rate of propellant under the pressure of 2 ~ 6MPa, the burning rate pressure index increased, Reduce, reduce the friction sensitivity and impact sensitivity, tensile strength and elongation of the same, has no effect on the chemical stability of propellants.
