摘　　要：利用基本物理原理探究配置出了电源电压和轨道电流分别大约只是电磁轨道炮的千分之一和百分之一的小型电磁轨道发射器系统,避免了轨道烧蚀缺陷,降低了对轨道和电枢材料的要求。与现有的电磁轨道发射系统设计相比,本原理从轻型武器的出膛速度出发,发现存在有最小电源电压,并用MATLAB数学软件推导出了这一加速电源电压最小值与外加磁感应强度直接解析表达式,进而导出了加速时间与出膛速度和轨道长度的关系式,为小型化提供了理论基础。同时,该系统既利用现有电磁技术就可实现的优势,又能获得较高的动力学效率。Based on the basic physical principles,a small electromagnetic rail launcher system,whose power electromotive force and orbital current were only about one thousandth and one hundredth of that of an electromagnetic railgun,respectively,was configured.It could not only avoid the defects of rail ablation but also reduce the requirements of rail and armature materials.Taking the muzzle velocity of light weapons into consideration,the minimum of supply voltage was found,and the analytical expression of this minimum value and the magnetic induction intensity was obtained by MATLAB software.The relational expression of acceleration time with the muzzle velocity and the rail length was then gained,which provided a theoretical basis for the miniaturization of electromagnetic rail launcher system.Compared with the existing design of electromagnetic rail launch system,it could achieve the goal of taking advantage of the existing electromagnetic technology,and that of gaining high dynamic efficiency as well.
