  • Abstract
    An experimental technique for directly measuring rail resistance during a railgun firing is described. A simple railgun flux loop is the only additional instrumentation (beyond standard instrumentation) required to determine rail resistance. Several tests were conducted to verify this rail resistance measurement technique. Typical test data for current, dI/dt, flux loop voltage, breech voltage and muzzle voltage are shown. It is concluded that the technique will permit the evaluation of advanced rail and railgun concepts such as cryogenic rail operation and transposed conductor rail performance
