An electromagnetic railgun projectile is disclosed which includes an aeroshell having a substantially flat surface extending along the length thereof. The substantially flat surface is configured to increase the lift-to-drag ratio of the projectile during reentry. The projectile also includes an armature integrated into the aeroshell substantially near the center-of-gravity of the projectile, and a plurality of extendable flaps attached to the aeroshell. The flaps are capable of stabilizing the projectile during an unguided portion of its flight and mane...
What is claimed is: 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 fli...
