含5/7单基药灌注炸药的制备及性能研究❋

摘要

[ ABSTRACT] Water-resistance perfusion explosives containing 5/7 single base propellant were manufactured by three kinds of fillers ( R1 , R2 and R3 ) . Filling problems in small pores was resolved by the improved technology. In underwater explosion, the TNT equivalent of perfusion explosive with R1 , R2 and R3 were 0. 97, 1. 11 and 1. 34 respectively, and energies of perfusion explosives obviously increase. Furthermore, energies of perfusion explosives were especially related with the characters of R1 , R2 and R3 . Detonations of perfusion explosives with the fillers of white, R2 and R3 were tested through high speed photography. Results show that fire balls are also different among high energy and low energy fillers, and the brilliance and shape of fire ball from R3 is more than those from R2 . Meanwhile, the perfusion explosive with the filler of white still shows inflammation. This result is also according with the effect from the underwater explosions.%针对5/7单基药,采用了R1、R2和R33种不同的填充材料制备抗水型灌注炸药。利用改进的工艺解决了5/7单基药小孔隙的填充问题；该炸药的水下测试结果显示,含R1、R2和R3的灌注炸药TNT当量为0.97、1.11和1.34,能量呈明显递增关系,结果与灌注液和发射药颗粒能量匹配相对应；对R2和R3灌注炸药以及5/7单基药颗粒的爆炸过程进行高速摄影,发现它们在相同时间段火球明显不同,R3灌注炸药火球亮度、大小及持续时间明显超过R2体系,这与水下爆炸结果相一致,而未灌注的5/7单基药颗粒在冲击作用下还存在燃烧现象。这些结果为配方设计提供了依据。
