【Abstract】 By means of X-ray flash radiographs,the jet formation and penetration of two types of shaped charge with large cone angle were investigated,and compared with that of the jet of shaped charge with small cone angle (42 °).The experimental results show that (1) the jet of shaped charge with large cone angle is characterized by a lower jet tip velocity and a very large portion of the liner mass,and (2) at a long standoff the depth of penetration in steel target is small,but the diameter of hole is large.更多还原
