【摘要】 为了研究炸药在激光作用下的影响特性,采用激光辐射装有三种炸药的约束装置,并利用温度测试系统记录炸药的温度历史曲线,分析了激光作用下不同炸药的相应特性及其差异。结果表明:相同功率下,激光辐射直径小,炸药温度升高速率快,且梯黑铝(THL)、梯奥铝(TOL)、PBXN-109延迟时间更短,点火温度更高,炸药反应完全性更充分;两种熔铸炸药相比,THL比TOL需要更长的延迟时间和更高的点火温度,两种炸药反应现象类似;不同类型炸药之间的对比PBXN-109炸药比两种熔铸炸药更钝感,且延迟时间差异更小,毁伤模式完全不同。更多还原

【Abstract】 To explore the response characteristics of explosives with the laser, the confined shells loaded with three kinds of explosives were irradiated by laser meanwhile the temperature-time profile of the explosives was obtain with temperature test system. The explosives’ response characteristics and difference were analyzed under the laser irradiation. The results show that in the same power, the laser radiation diameter is small and the explosive temperature rises rapidly, the shorter delayed time and higher ignition temperature, careful contrast of the two melt-cast explosives, more lag time and higher ignition temperature are needed for the THL than TOL and the reactive phenomena are the same. Compared with the different types of composite explosives, the PBXN-109 is more phlegmatized and the difference of lag time is less than the two types of melt-cast explosives, moreover the demolition effects are completely different.更多还原
