Abstract: By means of various thermal analytic methods,such as DSC, DTA, TG and DTG, the thermal decomposition characteristics of the aluminum magnesium fuel rich propellant and its main ingredients were investigated The thermal decomposition characteristics of AP/KP mixture are determined by the thermal characteristics of two oxidazers However, the thermal decomposition reaction of KP in the mixture can be catalyzed by AP decomposition The thermal decomposition process of the aluminum magnesium fuel rich propellant is a combination of the thermal decomposition reactions of AP, KP and the HTPB binders

摘要： 采用DSC、DTA、TG和DTG等热分析方法 ,研究了AP ,KP ,AP/KP混合氧化剂、AP/KP/HTPB模拟推进剂以及铝镁贫氧推进剂的热分解特性。研究发现 ,AP/KP混合氧化剂的热分解特性由两种氧化剂的热分解特性叠加而成 ,但AP的存在使KP热分解反应提前 ;贫氧推进剂的热分解过程由AP和KP的热分解、粘合剂的热分解等过程组成。
