摘要
The external strong magnetic field coupling with shaped charge is an effectively method to increase the penetration capability of the shaped charge jet. In this study, a theoretical model was developed to analyze the effect of the external strong magnetic field on breakup time and inhibition of rotation and drift of the shaped charge jet. The discharge current of the circuit system and the magnetic field of the shaped charge jet undergoing were calculated in detail. A series of depth of penetration (DOP) experiments were conducted to analyze the coupling mechanism between the external magnetic field and the shaped charge jet. Theoretical and experimental results indicated that the external strong magnetic field coupling with shaped charge jet can effectively improve the stability of the shaped charge jet, which the magnetic field can delay its breakup time and inhibit its rotation and drift. The ability of penetration of the jet produced by the empy set56 mm shaped charge is increased by 69.13% under the action of the external magnetic field.
