Study and Application of Mach Wave Techniques

Abstract

A theoretical and experimental study of convergent wave initiation and detonation techniques has been carried out. This included analytical and experimental studies of wave shapes and Mach discs in cylindrical explosive charges overdriven by concentric external faster explosives. The techniques were also applied to shaped charge systems. The results indicate that it is possible to overdrive TNT loaded shaped charges so that they perform as well as Composition B loaded charges. A depressurization disruption mechanism has been postulated to explain the jet breakup seen in flash X-ray and penetration observations, made when similar overdriving methods were applied to more energetic explosive systems like Composition B overdriven by PBX-9404.
