Ya. Kareev et At. Kuharenko, Metal bodies transition velocity in railguns with traditional and muzzle current supply, IEEE MAGNET, 35(1), 1999, pp. 409-412
The main factor preventing the attainment of high velocities with armatures
in railguns is the high current are. The are is a final stage of the skin
current process depending on the metal body velocity. The investigation of
the development of contact transition in two types of the railguns has been
carried out with the help of a two-dimensional code. The parameters influe
ncing the transition velocity value are determined.
