ABSTRACT:
An electromagnetic projectile launching system is provided with a rail configuration in the breech area which increases the electromagnetic field to increase armature acceleration and initiate sliding current transfer at a lower current. Two configurations are disclosed. The first comprises multiple rails disposed parallel to the launcher barrel rails in tne breech region and connected in series such that current in the multiple rails flows in the same direction as current in the closest barrel rail. Connecting shunts are disposed in equal numbers on opposite sides of the barrel rails to balance electromagnetic forces. The second configuration comprises nonparallel barrel rails containing a bend in the breech region.
