Abstract

In order to understand the effect of axial pulse magnetic field on the shaped charge jet (SCJ), we designed an experiment system and carried out related experiments based on the mechanism of a high-explosive anti-tank (HEAT) penetrating a target and the interaction between the magnetic field and SCJ, and came up with the key technology to match the time sequence between the formation of SCJ and the pulsed current generation of the coils, which was a major breakthrough. The experiment results show that the increment of the penetration depth for SCJ penetrating the target is largest when the voltage is 5 kV, the capacitor is 1 200 μF and the length of coil is 50 mm. The influence factors of the penetration depth are respectively the charging voltage of the capacitor, the capacitance and the coil length, each in a descending order. These results provide an important theoretical foundation and technical support for the feasibility demonstration, principle test and related physical design of the coil of the enhanced HEAT by the electromagnetic method.
