Abstract

A high pressure plasma initially formed from a fluidizable substance in a confined region of a passage behind a projectile in the passage initially accelerates the projectile toward an open end of the passage. The plasma in the confined region is ohmically heated to a higher pressure by a discharge current flowing longitudinally through the passage and the projectile.
