Experimental Study of Magnetic Field Inhibiting Rotation of Shaped Charge Jet Particles
Abstract
A shaped charge jet (SCJ) will break up into many particles after it undergoes elongation in free flight. However, if breakup of a SCJ occurs, the particles cannot remain aligned with the SCJ axis, but start rotating because of the effect of asymmetric force and perturbation [1; 2]. The effective length of SCJ will be decreased because of its tumbling, and its ability of penetration could be decreased. The external magnetic field delaying the breakup of SCJ has been researched, but so far, few people focus on the magnetic field inhibiting tumbling of SCJ particles. This work provides the experimental study for further research on the inhibition of tumbling of SCJ. Because the slug is easy to observe, this work takes it as a research object to analyze.
