ABSTRACT:
A quad armature electromagnetic rail gun uses four conducting rails, in a quadri-pole configuration, with four sliding armatures to propel projectiles. Two of the four conducting rails are positive, and receive one-half of the operating current. The four sliding armatures are slidably disposed between the two positive conducting rails and the two negative conducting rails, and each sliding armature conducts one-quarter of the conducting current therebetween. The quadruple configuration produces a minimum of magnetic interference at the center of the rail gun so that projectiles with electronic components need a minimum of magnetic shielding.
