Abstract: A projectile includes members that deploy upon impact with a target. The projectile includes a nose piece with a portion that shears off upon impact with the target, causing the nose piece to be pushed inside the projectile. As the nose piece is pushed inside the projectile, the nose piece pushes on members that deploy outwardly and lock into place, thereby greatly increasing the damage done to the target. The projectile is easily assembled by placing the two members through an axial cylindrical hole into slots, then placing the nose piece into the axial cylindrical hole. The deployable members are held within the body of the projectile in flight, and only deploy when the projectile strikes a target, greatly increasing the damage to the target.

Abstract: A method for the dispersion of projectiles from guns capable of firing multiple projectiles in rapid succession whereby some of the projectiles are modified by moving the center of mass of the projectile away from it's central axis and oriented prior to firing. This, in combination with bring fired from a rifled gun barrel, imparts velocity to the projectile upon exiting the gun barrel at right angles to the barrel. This velocity along with the higher muzzle velocity will cause the modified projectile to diverge away from the trajectory of a standard projectile. The magnitude of the divergence will vary with the distance the projectile's center of mass is away from its central axis, and the placement of the modified projectile strikes around the bull's-eye will be determined by the loading orientation of the modified projectile. Firing a multiplicity of standard and modified projectiles in rapid succession will produce an accurate dispersion pattern on a target, increasing the hit probability on that target.

Abstract: A variable drag projectile stabilizer is utilized by a training projectile to match the trajectory of a tactical projectile for up to 3 km while having a range limitation of 8 km. The stabilizer applies supersonic flow phenomena to alter the aerodynamic characteristics of a training projectile while in free flight to fulfill this requirement. The stabilizer uses a cowling supported by struts to provide tail lift and ensure a stable flight path. Supersonic flow is established through ducts formed by the cowling and struts when launched from a weapon. The flow remains supersonic until the projectile reaches the desired range but then quickly becomes subsonic (choked) due to shock waves emanating from interior angles in the ducts. The geometry of the ducts can be designed to create different shock wave patterns within the ducts.
