Overpulse railgun energy recovery circuit
This patent describes an overpulse railgun energy recovery circuit for propelling a projectile along a railgun. The overpulse rail gun energy recovery circuit comprising: a railgun having an effective inductance, the railgun having a breach end, a pair of parallel rails, and a muzzle end; source inductor for storing current connected across the pair of parallel rails of the railgun at the breech end thereof; means for initially charging the source inductor to an initial current for storage; switching means connected across the source inductor with a closed position for shorting across the source inductor and an open position for enabling current flow into the effective inductance of the breech end towards the muzzle end of the railgun; a muzzle switch connected across the pair of parallel rails of the railgun at the muzzle end thereof; and transfer capacitive means.
