中文摘要：

电磁轨道炮是利用电磁力将弹丸加速到超高速的新概念武器系统,可遂行直瞄打击、超高空或超远程投送弹药等多种作战任务.介绍了轨道炮的基本原理,从电能利用角度对轨道炮研究中电源与电力控制、轨道与电枢结构设计、超高速滑动电接触理论与技术以及轨道炮系统集成等关键技术进行了分析.依据电磁轨道炮发展规律及现有技术水平,分析其新的发展趋势为大炮口动能轨道炮设计、基于轨道发射的弹丸设计以及轨道长寿命研究,对新概念武器发展有一定参考意义.

英文摘要：

Electromagnetic railguns are new concept weapons which accelerate projectiles to a high value with electromagnetic force. They are possibly applied to various military operations such as direct attack,high-altitude or long-range launching of ammunition. An introduction is made of the basic prin-ciple of railguns. An analysis is made of the novel electric power supply and electricity control re-search,structure designs of armatures and rails,sliding electrical contact technologies,and the inte-gration technologies in electromagnetic launch from the perspective of the use of electricity. Based on the law development and current technical level of railguns,the new development tendencies are repre-sented by guns with high muzzle kinetic energy,railgun projectile design and the long-life of rails, which has a certain reference value for the development of new concept weapons.
