Study on Driving Current of Inductive Electromagnetic Launcher Effects on Projectile Outlet Velocity

The launch velocity of the projectile in the inductive electromagnetic launcher is affected by many factors. In this paper, the outlet velocity of the projectile influenced by the driving current is studied deeply. A simulation model is established by the Ansoft Maxwell electromagnetic simulation software and the relevant parameters of the system are set. The outlet velocity of the projectile is simulated with the different capacitor voltages and pulse widths of driving current. It can be seen from simulation results that the capacitor voltage and the driving current width have enormous effects on outlet velocity and outlet time. So, a reasonable choice of the capacitor voltage and the pulse width of driving current can make the projectile obtain a best outlet velocity.
