摘要: 通过闪光X射线摄影技术,研究了两种大锥角射流的特性及其对钢靶的侵彻,并与小锥角射流进行了对比。研究结果表明:大锥角射流的头部速度较低,但直径和质量较大,在大炸高条件下对钢靶的侵彻孔深度浅,孔径大。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.
