Abstract:
A kinetic energy training cartridge capable of launching a range limiting sub-projectile having a weight less than 3 pounds, allowing the sub-projectile to not exceed approximately an 8000-meter distance when fired at approximately a 10-degree elevation, and to meet a kinetic energy target dispersion requirement of up to approximately 4000 meters, comprising:a cartridge assembly; and a projectile assembly secured to the cartridge assembly; wherein the projectile assembly comprises the sub-projectile and a sabot; wherein the sub-projectile comprises a plurality of stabilizing fins, a projectile rod, and a nose; wherein the plurality of stabilizing fins are secured to the kinetic energy projectile rod; wherein the kinetic energy projectile rod is secured to the nose; wherein the plurality of stabilizing fins and the kinetic energy projectile rod are completely encapsulated in the sabot, so that the stabilizing fins and the kinetic energy projectile rod are not subjected to a differential pressure of propellant gases while traveling within a gun tube; wherein the nose is not encapsulated within the sabot; wherein the plurality of stabilizing fins do not protrude within the cartridge assembly; and wherein after launch from the gun tube, the sabot is discarded, allowing the sub-projectile to travel downrange to a target.
