Abstract
A multiple rails magnetic accelerator is presented. By means of an electric discharge, a magnetic field is created which moves an armature along the rails. These rails are made in such way they can stand multiple shoots without eroding. The launcher is configured such that the critical velocity of the armature increases along the axial direction towards the muzzle as it moves through the gun. The rails are separated with a proper electrical insulator and the whole structure can be surrounded by one or more shells to confine the barrel and apply compressive stress. The compressive stresses applied preload the rails and the composite barrel structure to resist overall forces encountered during projectile firing.
