| 摘 要： | 为研究高能推进剂的冲击损伤状态对其使用安全性的影响，以爆轰波为加载手段，对NEPE推进剂试样进行冲击损伤。经扫描电镜观察和密度测量，冲击试样的基体材料和固体颗粒破坏严重，密度降低。热分析实验表明，损伤有利于试样中硝酸酯热分解的进行。密闭爆发器实验显示，损伤使燃烧速度加快。

| Abstract: | The internal damage in NEPE(Nitrate Ester Plasticized Polyether) propellants caused by the action of detonation waves and its effect on propellant combustion are investigated experimentally.The damage characteristics are inspected by scanning electronic microscope observation on propellant samples.Thermal analysis tests for the samples show that the damage is helpful for the thermal decomposition of nitrate(NG/BTTN) in NEPE propellants,and the closed-bomb test shows that the burning rate is accelerated considerably by the internal damage in the propellants. |
