HIGH PERFORMANCE SOLID STATE ARMATURE USING COMPOSITE TAMPING

WE ARE PROPOSING A RADICAL DESIGN FOR A SOLID ARMATURE FOR EM GUNS WHICH ADDRESSES THE KEY LIMITATIONS OF SOLID ARMATURES. THE DESIGN USES THE TAMPING OF COPPER FILAMENTS WITH PYROLYTIC GRAPHITE IN ORDER TO RETAIN PHYSICAL INTEGRITY AND ELECTRICAL PROPERTIES TO MUCH HIGHER TEMPERATURES. IT ALSO RETAINS THE BRUSH CHARACTERISTICS AT MUCH HIGHER CURRENT DENSITY, TEMPERATURE AND PRESSURE THAN CONVENTIONAL MATERIALS. LASTLY IT ALLOWS FOR LITZING CONFIGURATION TO ADDRESS THE VELOCITY SKIN EFFECT IN THE RAIL. THE CONSTRUCTION TECHNIQUES PROPOSED ARE PRESENTLY USED IN OTHER AREAS.
