The influence of a magnetic field on the stability of a shaped charge jet is experimentally investigated at standoffs of 490, 650 and 800 mm. The experimental results without and with the magnetic field are compared in terms of the shaped charge jet form, stability and penetration ability. A theoretical model based on one-dimension fluid dynamics is then developed to assess the depth of penetration of the shaped charge at those three standoffs and magnetic conditions. The results show that the penetration capability can be enhanced in more than 70% by the magnetic field. The theoretical calculations are compared with the experimental results with reasonably good correlation. In addition, the parameters introduced in the theory are discussed together with the experiments at three standoffs studied.

在 490、650 和 800 毫米的间距下，通过实验研究了磁场对聚能射流稳定性的影响。从聚能射流形式、稳定性和穿透能力方面比较了无磁场和有磁场的实验结果。然后开发了基于一维流体动力学的理论模型，以评估成形装药在这三个间隔和磁性条件下的穿透深度。结果表明，磁场可将穿透能力提高70%以上。理论计算与实验结果进行了比较，具有较好的相关性。此外，理论中引入的参数与研究的三个对峙处的实验一起讨论。
