摘要:
为揭示RS211和GUHL两种含铝炸药水中爆炸近场冲击波的传播特性，采用高速扫描相机和阴影照相技术记录了近场冲击波沿柱形装药轴向的传播轨迹，结合RankineHugoniot关系推算出了近场冲击波传播速度及阵面压力随传播距离的衰减规律，并与TNT炸药的结果进行了对比。同时，还结合近场冲击波的初始参数和Goranson关系式计算出了炸药的爆压值。结果表明，初始冲击波阵面压力由大到小的顺序为RS211、TNT、GUHL，在压力的衰减过程中，铝粉的反应使得冲击波的压力衰减速率得到降低，且GUHL炸药近场冲击波阵面压力的衰减最为平缓。
Abstract:
To understand the propagation characteristics of closefield shock waves for aluminized explosives RS211 and GUHL by underwater explosion, propagation paths along the longitudinal direction of charge cylinder were recorded by shadow photography using a high speed scanning camera and processed to distancetime curves of close-filed shock wave. Their attenuation laws of propagation velocity and front pressure were deduced using the RankineHugoniot relationship and compared with these of TNT. Furthermore, with the initial parameters of shock wave the detonation pressures of these explosiveswere calculated based on Goranson relation. The results show the decreased initial pressures of shock wave in the order of RS211, TNT and GUHL, decreased speed of front pressure attenuation due to the reaction of aluminum which is minimal in GUHL.
