Parametric Profiling of Water-Jet Projectiles for EOD Disruptor Using High-Speed Imaging Technique

Abstract

Parametric evaluation of frangible projectiles, like water-jet for disrupter applications and explosively formed shape charge projectile is essential to assess the behavior and impact effect of the projectile at the target end. Being as frangible in nature parametric profiling of such projectiles are challenging as compared to solid projectiles. Available conventional methods for such type of measurement are limited to either average velocity of the projectile or only terminal effect at the target end. Parametric behavior analysis by conventional methods requires number of iterations and it’s not cost effective. This article presents the novel non-contact methodology for parametric profiling of water-jet projectile using highspeed imaging technique in the external ballistic zone. The proposed methodology can generate the continuous profile of velocity from muzzle exit, which is useful to analyze and assess the behavior and impact of a water-jet projectile in the zone of muzzle exit, inflight and the target point depending open field of view of imaging system.
