Abstract
Liquid-filled compartment structure consists of a bulk steel plate with matrix blind holes which are filled with liquid and a steel front plate to seal up the liquid with rings and bolts. The liquid-filled compartment structure can resist the shaped charge warhead effectively. This paper presents experimental and theoretical investigations of the penetration ability of the residual shaped charge jet emerging from the liquid-filled compartment structure after the penetration process at different impact angles. On the basis of shock wave propagation theory, the influence of the liquid-filled compartment structure on jet stability is analysed. The interferences of the liquid backflow caused by a reflected shock wave and a back plate on jet stability under different impact angles are also examined. In addition, the range of the disturbed velocity segments of the jet at different impact angles and the penetration ability of the residual jet are obtained. A theoretical model is validated against the experimental penetration depths.
