摘　　要：为有效评价改性双基推进剂的热安全性,采用差示扫描量热仪和热自燃实验装置,研究了一种新型改性双基推进剂GHT推进剂的热分解和热自燃过程,得到了不同老化时间下GHT推进剂的热分解特性和热自燃特性。通过数据计算和分析,得到了GHT推进剂的热分解动力学参数、热安全性参数和热自燃动力学参数。研究结果表明,环境温度升高或老化时间的增长,都会导致GHT推进剂热安全性变差。To evaluate thermal safety of a CMDB propellant effectively,the thermal decomposition and self-ignition procedure of GHT propellant were studied by a differential scanning calorimetry（ DSC） and a set-up of thermal self-ignition. Curves of thermal decomposition at different rate,time to self-ignition and curves of thermal self-ignition of GHT propellant at different aging time were obtained respectively. By calculating and analyzing the data,thermal decomposition kinetics parameters,thermal safety parameters and self ignition parameters. The studies have revealed that,increasing environment temperature and time of storage make thermal safety of GHT propellant worse.
