摘　　要：开展了固体填料粒径、黑索今(RDX)/高氯酸铵(AP)相对含量、硝酸酯增塑剂种类、硝酸酯增塑剂与黏合剂增塑比、环境因素以及燃速催化剂种类和含量对推进剂燃速温度敏感系数的影响研究。结果表明,选用粗粒度的AP、硝酸酯基含量高的硝酸酯增塑剂、硝酸酯增塑剂与黏合剂增塑比低以及添加燃速催化剂有利于降低推进剂的燃速温度敏感系数。通过对以上影响因素的综合调节,当配方中燃速催化剂RTB质量分数为3.5%时,叠氮微烟推进剂的燃速温度敏感系数为0.18%/℃。The studies on the effects of solid filler particle size,relative content of hexogen(RDX)/ammonium perchlorate(AP),type of nitrate ester plasticizer,plasticization ratio of nitrate ester plasticizer and binder,environmental factors,as well as type and content of burning rate catalyst on the burning rate temperature sensitivity coefficient of the propellants were carried out.The results showed that the selection of coarse-grained AP,nitrate ester plasticizer with high nitrate ester group content,low plasticization ratio of nitrate ester plasticizer and binder,as well as the addition of burning rate catalyst were beneficial for reducing the burning rate temperature sensitivity coefficient of the propellants.By comprehensively adjusting the above influencing factors,when the mass fraction of burning rate catalyst RTB in the formula was 3.5%,the burning rate temperature sensitivity coefficient of azide minimum smoke propellant was 0.18%/℃.
