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41μn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。
The double sensitivity VISAR was used to test the detonation reaction zone thickness of small booster charge. The test uses JO-9C and HNS booster. The charge diameter is 6mm and 4mm, and the restraint conditions are 45 ~ # steel and plexiglass. Using 41μn thick aluminum foil as the particle velocity carrier, the interface particle velocity The whole process. The results show that the reaction time of JO-9C small size charge is about 40ns, the corresponding reaction zone thickness is about 0.22mm and 0.23mm, the reaction time of HNS small size charge is about 120ns, and the corresponding reaction zone thickness is about 0.60 mm.
