Study on liquid-filled structure target with shaped charge vertical penetration

Abstract

Based on the characteristic expanded hole of a shaped charge jet (SCJ) for target penetration and the reflow characteristics of liquids, the liquid-filled structure of a target disturbs the stability of the SCJ acquired in two independent parts. The interference jet speed interval, the escape jet speed interval, and the surplus depth are calculated on the basis of the virtual origin theory. The experimental results, including the velocity of the escaped jet tip and the surplus depth of penetration, are consistent with the theoretical results. Experiments show that the theory can describe the interaction process of the target with a shaped charge jet. Keywords: Shaped charge, Liquid-filled structure target, Disturbed jet, Escape jet
