To study some of the mechanisms in passive electromagnetic armor (PEA), the pulse current skin effect and the action of the current along the length of a shaped charge jet as it passes through PEA are researched. Considering the different characteristic of the pulse current from the alternating current, a frequency domain analysis method of skin effect is introduced. With the background of PEA, time...
The inductive coil launcher utilizes the theory of magnetic coupling between the driving coil and the armature. The armature is accelerated when the direction of induced current in it is opposite to the current direction in the driving coil, or else it will be slowed down. By the finite element analysis, the relationship between the induced current, the velocity of armature, and the waveform of current...
The direction of the induced current in armature will be reversed during the moving. In order to improve the efficiency of the electromagnetic driver, it is better to make the peak point of driving current be ahead of the reverse point. There are two factors to affect the induced current in armature: the variation of the driving current and the movement of armature. It obtains the position relationship...
