Flash Radiographic Studies of Hypervelocity Projectile Interactions with Explosives

Abstract

This report describes multiple, flash radiographic techniques developed in an investigation aimed at understanding and predicting the processes which occur when a hypervelocity projectile interacts with explosive filled ordnance. Hypervelocity projectiles were generated by shaped charges and characterized by multiple flash radiography. Explosive/metal target assemblies were designed to be representative of various aspects of explosive filled ordnance or components. The techniques have been used to study the projectile impact on bare explosive, penetration through covers into explosive, the supersonic projectile penetration of the explosive and the evolving structure of the bow wave shock that forms several millimetres in front of the projectile tip, the onset and progress of detonation both forward and backward in the explosive and the relative contribution of spall and jets in behind-the-plate initiation of explosives.
