摘要:

利用冲击感度和摩擦感度测试研究了聚叠氮缩水甘油醚／硝酸铵（ＧＡＰ／ＡＮ）推进剂及其常用组分的安全性能，指出了影响ＧＡＰ／ＡＮ推进剂冲击感度和摩擦感度的主要因素为硝酸酯（ＢＴＴＮ／ＮＧ），ＡＰ，ＨＭＸ等添加剂。硝酸铵具有非常低的冲击感度和摩擦感度，是理想的低易损性推进剂的氧化剂。硝酸酯增塑的ＧＡＰ／ＡＮ推进剂不仅具有较高的能量，而且安全性能显著优于ＧＡＰ／ＡＰ，ＧＡＰ／ＨＭＸ，ＧＡＰ／ＨＮＦ推进剂。

Abstract:

The safety property of GAP binder and oxidizers(AN,AP,HMX,RDX)and GAP/AN propellant was studied by testing of impact sensitivity and friction sensitivity.The tests indicat that nitrate ester(BTTN/NG),AP,HMX have worse effect on sensitivity of GAP/AN propellant. Ammonium nitrate is an ideal oxidizer of low vulnerable propellant with the lowest sensitivity.GAP/AN propellant plasticized with nitrate ester(BTTN/NG)not only has higher energy,but also is superior to other GAP propellants in safety property
