Patent ID: 7568433

Claim:
A finless projectile for firing from a barrel of a weapon, to impart kinetic energy to a target, comprising: an inner hollow core; a slug including a cylindrical body and a tip; a cylindrical forward projectile body that forms the inner hollow core and that includes a front open end and an aft open end, wherein when assembled, the front open end integrally engages the cylindrical body of the slug; a generally cylindrical aft projectile body that forms the hollow core and that includes a front open end and a closed aft end, wherein when assembled, the front open end integrally engages the forward projectile body; an obturator disposed between the forward projectile body and the aft projectile body, wherein the obturator seals propellant cases inside the weapon; wherein the finless projectile is full bore so that a cross-section of the forward projectile body approaches a cross-section of the barrel, thus eliminating the need for a sabot; wherein the finless projectile includes a center of gravity and a distinct center of pressure, wherein the center of gravity is disposed forward of the center of pressure, in order to provide static stability to the finless projectile; and wherein the tip of the slug has a truncated bullet shape to transfer the kinetic energy to the target, wherein the aft projectile body comprises an aft circumferential flange with grooves that are disposed at an angle relative to a longitudinal axis of the finless projectile, in order to induce spin during flight, wherein the finless projectile further comprises a pad that attaches to the aft surface of the aft projectile body, in order to absorb forces on the projectile from mechanical contact.
