ABSTRACT:
A gun for rapidly firing projectiles from a package inserted into a magazine as a cartridge and which are automatically fed into a propelling chamber and barrel connected thereto by a continuous stream of high pressure gas, a portion or all of which flows through the magazine. The flow of propellant gas is started and stopped by a manually or automatically controlled gate and the rate of firing and muzzle velocity of the projectiles are controlled by varying the pressure of the propellant gas, the geometry of the propelling chamber, or both. The magazine is so shaped as to deliver projectiles into the propelling chamber successively and the propelling chamber is so shaped as to direct the projectiles forwardly therein and form alternating slugs of gas and projectiles. The outlet from the propelling chamber may be connected through a flexible tube or directly to a curved or a conventional barrel. If a curved barrel is used, one of the surfaces of the interior of the curved barrel and exterior of the projectiles is formed to induce a rotary motion to the projectile as it passes through the curved barrel. The propellant gas may be carried in a gas container as a compressed gas, or in liquid form, or it may be generated as required by chemically generated gas. The gun may be carried on the person, it may be mounted in a fixed position, or it may be mounted on a vehicle, ship or aircraft.
