摘要
利用高压差示扫描量热法 (DSC)研究了含不同燃速调节剂 (亚铬酸铜、草酸铵、碳纤维 )的RDX AP HTPB推进剂热分解性能 ,研究发现 ,调速剂对推进剂燃速的影响与其对推进剂主要组分 (RDX、AP和HTPB)峰温、推进剂初始放热量的影响密切相关。燃烧催化剂亚铬酸铜和碳纤维使RDX、AP的分解峰温降低 ,使推进剂的初始分解阶段放热量增大 ,分解放热峰增多 ,故导致推进剂燃速增加 ,而草酸铵使RDX的分解峰温升高 ,使推进剂的初始分解阶段放热量降低 。
The effects of different burning rate regulators on the thermal behavior of RDX/AP-HTPB propellant were studied. The results show that the effect of the burning rate regulator on the burning rate depends on its effect on the thermal behavior of RDX/AP/HTPB propellant. The decomposition peak temperature of RDX and AP is decreased, and the first decomposition stage of RDX/AP/HTPB propellant releases more heat, at the same time the number of the decomposition exothermic peak increases because of the effect of CuGr2O4 and carbon fiber, so the burning rates of propellant increase. The decomposition peak temperature of RDX becomes higher and the first stage decomposition heat of RDX/AP/HTPB propellant reduces at the effect of the combustion inhibitor (ammonium oxalate), accordingly, the burning rate of propellant containing the combustion inhibitor is lower.
