Research on Armor Debris Cloud Characteristics of Shaped Charge Jet Penetrating Target Vertically

Abstract

When shaped charge jet (SCJ) penetrating finite thickness target, penetration depth and armor debris cloud are major determinants of damage degree. Especially for the interior equipment and personal of armor vehicle, extent of damage mainly related to the armor debris cloud distribution characteristics. A great number of studies on armor debris cloud that generated by SCJ have been done by domestic and foreign scholars. Research methods on this issue have mainly concentrated on numerical calculation and experiment. Therefore, it is not satisfied due to the formation mechanism analysis on the armor debris cloud lacked. In this paper, the debris cloud that generated during the process of SCJ penetrating target was divided into three parts - front, middle and rear. Theory analysis on the armor debris cloud formation mechanism, space and velocity distribution had been preliminarily studied based on the propagation character of shockwave and penetration characteristic of jet penetration on target. The theoretical calculation results are in good agreement with experimental results of X-Ray imaging test.
