Abstract

An electromagnetic projectile launcher or railgun capable of withstanding hundreds or thousands of shots. The railgun features a current management system having guard plates which act to reduce peak rail current densities while also maximizing projectile velocity. Guard plates can be used in either square or round bore designs and can be powered by either a single or separate power supply from that of the rails.
