摘　　要：通过激光粒度仪分析了Mg/Al合金粉的粒径及粒度分布。利用TG-DSC热分析仪分析推进剂的热分解特性。用燃烧实验装置研究了推进剂的火焰结构,并对CMDB,Al-CMDB,Mg-CMDB和Mg/Al-CMDB推进剂四种火焰结构进行比较。用SEM和EDS研究了CMDB推进剂的熄火表面形貌和表面特征组成。结果表明:Mg/Al-CM-DB推进剂在DSC曲线上存在一放热峰660.3℃。Mg/Al合金粉改变了推进剂的燃烧状态,提高金属燃料Al粉的燃烧效率。The particle size and distribution of particle size of Mg/Al were analyzed by Mastersizer. The thermal characterisitics of CDMB propellant were analyzed by TG-DSC. The flame structure was studied by using the burning device and the differences of the flame structure were compared amongst CMDB, Al-CMDB, Mg-CMDB and Mg/Al-CMDB propellants. The surface appearance of the propellant quenched and surface composition were researched by the SEM and EDS. The results show that the Mg/Al alloy has a peak 630.3℃ of the heat of CMDB propellant. The combustion condition of CMDB propellant with Mg/Al is changed. Meanwhile,the metallic Al fuel combustion efficiency is improved.
