Abstract: This patent is for an apparatus which increases the muzzle velocity and energy of a supersonic projectile for a given set of ballistic conditions. When a projectile is fired from a barrel, there is typically a great deal of available energy still remaining in the combustion gas. This energy is released from the muzzle without being used when the projectile exits. Friction between the barrel and projectile, and the length, cost, and weight of the barrel limit the amount of energy which can be transferred into the projectile. This apparatus may constitute an attachment to the end of a pistol, rifle, or other gun; it may be a modification to the barrel of a gun; or it may be incorporated into an entirely new barrel for a gun. The apparatus consists of a non-contact section, and a diverging section followed by a straight, constant area section, and optionally followed by a short converging section.

Abstract: In an open chamber air gun, a round is gravity fed or magnetically fed into the open chamber and falls into the magnetic flux lines of a magnet disposed at the chamber. Due to the magnet, the round is pulled securely into the chamber and then remains momentarily held in place, blocking much of the air behind it and thus increasing the air pressure driving it. When the round moves down the barrel from the breech toward the muzzle, it quickly leaves the vicinity of the magnet and the magnetic drag ceases, after which the air pressure is free to drive the round to full velocity. High rates of fire and muzzle velocities are achieved with moderate air pressure and an action with no moving parts.
