| 摘 要： | 以大型落锤为加载手段,对高能ＮＥＰＥ推进剂试样产生损伤。扫描电镜观察,基体材料破坏,而固体颗粒无明显变化。热分析试验表明,损伤对以硝酸酯为主的基体材料的热分解有影响。密闭爆发器试验显示,损伤对燃烧稳定有明显影响。

| Abstract: | Low speed impact tests for inducing damage are conducted on NEPE (Nitrate Ester Plastized Polyether) by using the large scale drop weight apparatus.The scanning electron microscopy (SEM) shows that the matrix materials have been destroyed,and the particle filled materials have not changed apparently.The results of thermal analysis show that the damage affects thermal decomposition of nitrate(NG/BTTN).The closed bomb tests manifest that the apparent burn rates of damaged NEPE propellants vary considerably. |
