Propagation Characteristics of Close-field Shock Wave for Two Aluminized Explosives by Underwater Explosion
摘要
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.关键词
