Metal Armatures for Railguns

Abstract

Proper design of a metal armature for a railgun projectile is vital to obtain optimal performance and to reduce rail wear. Previous armature designs did not include the contribution of friction to the heat of the rail-armature interface. A simplified model of the electromechanical heating of the armature was developed and used to redesign an armature for the EMACK railgun at the Armament Research and Development Center. A new integrated armature-sabot package was constructed and test-fired.
