摘要/Abstract

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 ,所以导致推进剂燃速降低

Abstract: The effects of different burning rate regulators on the thermal behavior of RDX/AP HTPB propellant were studied. The results show the relationship between the effect of the burning rate regulator on the burning rate and that on the thermal behavior of RDX/AP/HTPB propellant is close. 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 affect of CuGr 2O 4 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.
