Analysis of a series augmented railgun launching process

For characterizing the series augmented railgun launching process, the study from analysis of muzzle voltage was insufficient since armature velocity, resistance and voltage drop of armature were also important to the launching process. In the present work, the variations of armature velocity, total resistance and voltage drop of armature against time were investigated based on the data of B-dot probes (to measure position of armature), Rogowsky coil (to monitor current) and high voltage probes (to observe muzzle voltage). Results indicated that, the voltage drop of armature and total resistance showed roughly the same trend as the change of velocity. There were obvious stages observed in two-turn series augmented railgun launching process.
