Analysis of current distribution in the zone of high speed sliding contact of the pulsed electromechanical converters

At a high enough velocity of moving body in electromagnetic rail accelerator (1.5...2.0 km/s and more) a relaxation time for a field is much less than a time of body replacement along the rails. The calculation expressions and algorithm for a building of 2D magnetic field and current density distribution are obtained with a using of the Green's functions method in the approximation of stationary diffusion for the area in the neighborhood of the angle point of contact at the rectangular form of moving electrode's cross section. The integral equation with integrated nuclei has been obtained for a magnetic field on the contact border of media. The algorithm of its solution has been realized and pictures of the field distribution at different ratio of electrical conductivity coefficients for contacting media have been built.
