Abstract:
For characterizing a series augmented railgun launching process, the simulation and experiment were done. In the experiment, only observation of muzzle voltage, current and armature position were insufficient to analyze launching process deeply since armature velocity, resistance force and voltage drop of armature were also important to the launching process. In the present work, based on MATLAB／SIMULINK software platform, the simulation model was built, and the dynamic characteristics of system were simulated. Furthermore, the variations of armature velocity, total resistance force 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). The results indicated that, the voltage drop of armature and the total resistance force showed roughly regulartendency. There were obvious stages observed in the two turn series augmented railgun launching process.
Key words: armature electromagnetic launching inductance gradient muzzle voltage series augmented
