Shaped Charge with Large Cone Angle Penetration to Concrete Target

The penetration capability of two kinds of shaped charge with large cone angle for concrete was studied by using X-ray flash radiographs,penetration effect test and numerical simulation.The shaped profiles and tip-tail velocities of the penetrators formed by the shaped charge with truncated liner was obtained in the experiment,its penetration parameter was also measured for concrete targets with semi-infinite thickness and multi-layer limited thickness.The formation process and penetration process of the shaped charge with two types of liner structure were obtained by AUTODYN-2D numerical simulation.The results show that the parabolic liner can form ideal shaped charge with jetting projectile and generate penetration hole in the concrete target which can satisfy the tandem warhead to the precursor shaped charge.
