Abstract:
1. An electromagnetic railgun projectile comprising: a non-axisymmetric aeroshell having an aerodynamic lifting surface extending along a length thereof for increasing a range of the projectile; a armature integrated into the aeroshell near the center-of-gravity of the projectile; and a plurality of flaps attached to the aeroshell, wherein the flaps are extendable and retractable during flight away from and towards the aeroshell and into and out of a flow field of the projectile in order to control a path of the projectile during flight, wherein the armature is for passing current from one electromagnetic rail through the armature to another electromagnetic rail in order to launch the projectile and the aeroshell is defined by holes and surfaces of the armature pass through the holes in order to make contact with the rails.
