Abstract
Air as conventionally known is comprised of about 78% nitrogen and 21% oxygen with other trace gases such as carbon dioxide, neon, and hydrogen. Other gases (e.g. helium) and partial vacuums have both a lower density and a higher speed-of-sound from that of conventional air or even some highly utilized propellant gases. The present application and described embodiments take advantage of these principles to provide a purge gas mixture and system to increase the speed of a projectile exiting the muzzle-end of a gun barrel. A partial vacuum may also be used in certain applications.

An apparatus for use for launching a projectile comprising:
- a trigger coupled to a firing mechanism;
- a breech for loading the projectile,
- wherein the projectile has a propulsive charge and projectile body,
- a barrel having a breech end and a muzzle end;
- and
- a purge apparatus configured to purge air and other gasses from an interior of the barrel thereby displacing and replacing the air and other gases with a purge gas,
- wherein the purge apparatus is activated before the launching of the projectile.
An apparatus for use for launching a projectile comprising:
- a trigger coupled to a firing mechanism;
- a breech for loading the projectile, with the breech holding h projectile,
- a barrel having a breech end and a muzzle end,
- wherein the projectile is configured to be expelled from the barrel;
- a membrane disposed over and adhered to an opening of the muzzle end of the barrel;
- and
- a purge apparatus configured to purge air and other gasses from an interior of the barrel thereby displacing and replacing the air and other gases with a purge gas,
- wherein the purge apparatus is activated before the expelling of the projectile.
