| 摘要: |
| 研究了轨道-线圈复合型电磁炮的驱动力、轨道-线圈交叉作用及其对系统性能的影响，提出了改进型的四轨复合炮。理论分析与数值计算表明：在普通的双轨复合炮中，交叉作用会使弹丸与炮管间存在较大的横向压力，导致弹丸运动不稳定及产生摩擦阻力，而四轨复合炮基本消除了交叉作用的不利影响，系统性能显著优于双轨复合炮。 |

| Abstract: |
| The drive force, the rail-coil cross interaction and the system performance of the rail-coil combined electromagnetic gun have been researched, and an improved structure with four rails distributed symmetrically has been proposed. The theoretical analysis and numerical computation of the structure show that the rail-coil cross interaction brings considerable transverse pressure and motion instability to the normal two-rail combined EM gun, while the four-rail combined EM gun successfully eliminates the negative effect of the cross interaction and obtains much better performance. |
