  • Controlled terminal kinetic energy projectile
    Patent number: 6722283
    Abstract: A non-lethal projectile includes a projectile body; a fuze disposed in a rear of the projectile body; an expelling charge disposed adjacent the fuze; a wad disposed adjacent the expelling charge; a dense powder ballast disposed adjacent the wad; a non-lethal payload disposed adjacent the dense powder ballast; and an end cap disposed on a front end of the projectile body; wherein the expelling charge expels the dense powder ballast and non-lethal payload and reduces the forward kinetic energy of the projectile body and the fuze to one of a near non-lethal or non-lethal level such that as the projectile body and the fuze travel from a burst point to a target impact a residual kinetic energy of the projectile body and the fuze is non-lethal.
