  • Aerodynamic projectile and means for propelling same
    Patent number: 5469790
    Abstract: An aerodynamic planar projectile carries an exposed propellant charge. The projectile is loaded into a specially designed gun that has a firing chamber and a barrel designed to receive and guide the projectile. When the trigger is pulled, an electric current heats an element which ignites the propellant. The propellant explodes driving the projectile from the chamber and down the barrel with lethal velocity.
    Type: Grant
