| 摘 要： | 利用双灵敏度VISAR测试了小尺寸传爆药装药的爆轰反应区厚度.试验采用JO-9C和HNS传爆药,装药直径为6mm和4mm,约束条件为45~#钢和有机玻璃,利用4μm厚的铝箔作为粒子速度载体,得到了装药与LiF窗口界面粒子速度的全过程.结果表明:JO-9C小尺寸装药的反应时间约为40ns,相应的反应区厚度约为0.22mm和0.23mm;HNS小尺寸装药的反应时间约为120ns,相应的反应区厚度约为0.60mm. |

| Abstract: | Detonation zone length of small booster charges were measured by Bi-sensitivity VISAR. The diameters of small charges of JO-9C and HNS booster were 6mm and 4mm with confinement of 45 steel and PMMA. The interface velocities of charge/LiF were measured by using aluminum foil with thickness of 4μm as the carrier of particle velocity. Experimental results show that the reaction time of small JO-9C charge is about 40ns while HNS is about 120ns,and the corresponding detonation zone lengths are 0.22mm and 0.23mm for JO-9C while 0.60mm for HNS. |
