CONCEPT OF A NOVEL MULTISTAGE RAILGUN LAUNCHER

Qing Lu

Abstract

The electrothermal properties and conversion of solid armature in electromagnetic railgun were analyzed. The conversion at a high velocity in conventional railgun cannot be overcome, and brings about erosion, which determines the launcher′s bore lifetime, launch velocity and operational limits. A novel multistage railgun could avoid the conversion and most important, the erosion.
