ABSTRACT:
The present invention relates to projectiles that are particularly useful in guns having smooth bores, but it is equally useful in guns having either smooth or rifled bores. The present projectiles are cylindrical, tubular composites comprised of low density and high density materials. The present projectiles have a heavier forward portion and a lighter rearward portion. The distance from a point at the rear of the projectile to a plane perpendicular to the axis of the projectile and passing through the center of mass of the projectile is from about 1.0 to about 5.0, and more preferably from about 1.2 to about 1.8, and most preferably from about 1.2 to about 1.6, times the distance from a corresponding point at the front of the projectile to such plane. The present projectiles may also include a guidance system consisting of internal vanes, or fins, positioned within the projectile body. The present projectiles present substantially less head-on surface area when the projectile is in flight. Thus the initial velocity of the projectile decreases at a substantially slower rate than projectiles now in use. The design of the present projectiles enables the projectiles to have a flatter trajectory and carry more kinetic energy to the target.
