Analysis and discussion on launching mechanism and tactical electromagnetic railgun technology

摘要：

　　This paper begins with a discussion on the significance of multi-physical fields in the research of railgun launching mechanism, followed by an introduction of research work about dynamic measurements and numerical simulations.The application of some measurement methods including the atomic emission spectrum, fiber-optic strain, optical level, pulsed X-ray, and high-speed video in observing the launching process was introduced.The models about the electromechanical dynamic processes and multi-physical fields in a railgun were developed.The mechanisms of the grooving, arc transition, and gouging were analyzed.These work provided a deeper understanding of launching mechanism of electromagnetic railgun.Some issues about the tactical railgun, such as the fiber composite overwrapped barrel, recoil, loading modes and eddy current loss were also discussed.Taking a medium-caliber launcher as an example, the basic process of design and analysis was introduced.
