| Abstract: | The erosion of electrode surfaces is reduced with an external magnetic field control and the strength and distribution of the external magnetic field are calculated. The coils of the external magnetic field control are placed at the breech that the plasma armature is accelerated initially. The magnetic field control enhances the magnetic force to the projectile, resulting in the erosion of electrode surfaces is reduced. The experimental study is also performed. |
| Keywords: | railgun electrode erosion magnetic field control |
