Abstract
Narrow collateral cavity electromagnetic guns with two wall conductor assemblies with a divide plane proximal barrel bus and array of wall conductors extending therefrom to contact means proximal the half cavity's narrow wall in each collateral cavity half, like potential power rails at the narrow walls and a midline power rail in a wall there between. Each collateral half of projectiles for use therein have: a propulsion bus orthogonal the cavity's axis continuous the said midline power rail at one end and propulsion bus-aft shunt current bus the other, and forward and aft current shunts on both sides of the projectile's collateral halves. Projectile's current buses co-act with said assembles, shunts and power rails circulating the gun's current around both sides of the propulsion buses and the magnet fields of said circuit interact with the propulsion buses' currents creating forces therein propelling the projectile through the barrel cavity.
