  • Conducting phase change material armature for an electromagnetic launcher system
    Patent number: 5385078
    Abstract: Electromagnetic launcher apparatus which includes a set of conductive rails and a projectile having an armature which comprises both primary conductive material and phase changeable conductive material. This conducting, phase change material armature comprises material which when exposed to friction induced heat changes from solid to liquid form during the launching of projectiles along the conductive rails. This conducting, phase change material armature has decreased mass particularly useful for long barrel launches.
