摘要：

If the velocity-skin effect could be eliminated, solid-armature railguns might reach high velocity (greater-than-or-equal-to 6 km/s) without forcing most of the armature current to pass through an arc. Even then, magnetic diffusion (the ''normal'' skin effect) will limit acceleration. In this paper, the performance limits for railguns which are free from the velocity-skin effect are investigated by deriving the upper limits for a specific kind of power supply. Previous performance estimates made for solid-armature railguns are examined in the light of these results and are found to be relatively very optimistic. A railgun design which limits the velocity-skin effect and which may allow improved performance for solid armatures is
