采用量热仪、燃速仪、PDSC 分别研究了含不同粒度和含量 Al 粉的高燃速 AP／CMDB 推进剂的爆热、燃烧性能与热分解特性。结果表明，推进剂爆热与 Al 粉的含量成正比；Al 粉质量分数为0～8％时，对推进剂燃烧性能无明显影响；Al 粉粒度由14μm 减小至5μm 时，推进剂爆热降低40 J／g，热分解放热量增加107 J／g，7～10 MPa 压强下推进剂燃速提高1～1．8 mm／s，7～22 MPa 下压强指数由0．56降至0．50；当 Al 粉（质量分数3％）粒度减小为150 nm 时，推进剂的爆热降低93 J／g，热分解放热量增加343 J／g，18～22 MPa 压强下的燃速提高2～3 mm／s。

The heat of combustion,combustion performance and thermal decomposition characteristics of AP/CMDB propellants containing Al powder with different granularity and content were researched by using calorimeter, burning rate measurement and PDSC,respectively.The results indicate that the heat of detonation is proportional to the content of Al powder.The Al powder content in the rang of 0 - 8% (mass fraction)has less effect on the combustion performance of propellants.As the granularity of Al powder decreases from 14μm to 5μm,the heat of combustion decreases by 40J/g and the heat of exothermic decomposition increases by 107J/g,the burning rates in the pressure range of 7 - 10 MPa increase by 1 - 1.8 mm/s and the pressure exponent in the pressure range of 7-22 MPa decreases from 0.56 to 0.50.As the granularity of Al powder (mass fraction of 3% )decreases to 150nm,the heat of detonation decreases by 93 J/g and the heat of exothermic decomposition increases by 343 J/g,the burning rates in the pressure rang of 18-22 MPa increase by 2-3 mm/s.
