Explosive reactive armor: theoretical and experimental studies

Abstract

Study of interaction of explosive reactive armor (ERA) with shaped charge jet is the basis for evaluation of ERA effectiveness. Theoretical model of this interaction is given. It is incorporated in the ERASC computer code. Experimental investigations comprise influence of upper and down plate thickness, jet attack angle, distance between ERA and main armor, etc. Computational results of ERASC code are compared with experimental data. Very good agreement between computational and experimental results of penetration in the steel target is observed. The developed code enables optimisation of explosive reactive armor.
