国外GAP推进剂研制现状

Current Developraeot Status of Abroad GAP Based Propellants

综述了缩水甘油叠氮聚醚(GAP)及其推进剂的热、力学及弹道性能,GAP推进剂有较高的燃速和能量,但其燃速压强指数和温度敏感系数偏高。GAP推进剂的力学性能较差,改性GAP和支化GAP更具吸引力。GAP推进剂可用于燃气发生剂、微烟推进剂、高能推进剂及改性双基推进剂。

The thermal, mechanical and ballistic characteristics of glycidyl azide polymer (GAP) and GAP based solid propellants have been reviewed. GAP offers propellant system with higher burning rate, higher energy, but brings about boring higher pressure exponent and temperature sensitivity. The mechanical properties of GAP based propellants arc rather poor. Hence, the modified GAP and branched GAP should be mote promising GAP based propellants can be used in gas generators, minimom smoke propellants, high energy composite propellants and modiified double base propellants.
