Structural Design and Experimental Study on Forward Shaped Charge and Explosion-Proof Body for Tandem Warhead

The forward shaped charge's penetrative technology and the two-stage explosion-proof technology are two key technologies in the studies of tandem warhead. Based on theoretic analysis and experimental study, we have analyzed the forward charge's structure and its blast effect on the follow-through penetrator, and conducted a design for the experiments of forward shaped charge penetrating concrete target by using porous aluminum as explosion-proof measure. The experimental results show that the forward charge penetrating concrete target forms a hole of 8.2 and 0.4～0.6 times the size of forward charge's diameter in depth and in diameter, repectively; and porous aluminum explosion-proof body effectively protects the follow-through penetrator being damaged from the forward charge's blast impact.
