| Abstract: | A proj ectile can be accelerated to hypervelocity by electromagnetic railgun.But the inductance gradient of a simple railgun is only about 0.45μH/m.It is so small that the railgun can hardly reach hypervelocity without erosion.The influence of the armature on inductance gradient of a simple railgun is analysed by using software Ansoft Maxwell 14.0,and the conclusion that it is necessary to take the influence of armature into account is gotten.To increase the inductance gradient of the augment railgun,the influence effect of the inductance gradient on augment railgun is analysed,such as the space between rails,the thickness of rails,and the muzzle width of the augment raligun.The inductance gradient changing rules as the rails parameter changing is obtained,which have some significance to increase the inductance gradient of the augment railgun in engineering practice. |
