The method may also include heat treating the coating layer(s), contouring the outer coating layer, applying a ceramic top coating to the contoured outer coating layer of the gun barrel liner, and/or sealing the gun barrel with a liquid metal sealer. | ||||||
| 264 | Light Gas Gun | US14205064 | 2014-03-11 | US20160161212A1 | 2016-06-09 | David Wayne Bergeron |
| An improved light gas gun launches a projectile in a light gas atmosphere as it travels through a frictionless barrel to achieve high muzzle velocities, decreased acoustic signatures, and increased ranges. The light gas atmosphere is introduced by a purge valve prior to firing or by a muzzle valve that holds a positive light gas pressure on the barrel and breech. The muzzle valve also routes the majority of propellant gases through a suppression canister, reducing the light gas gun's acoustic signature. The frictionless barrel uses light gas propellant routed through gas bearings to keep the projectile centered in the barrel and preclude the projectile from contacting the barrel walls, eliminating barrel wear. The system includes a projectile assembly that stores light gas from the firing and injects it into the boundary layer, reducing drag, increasing range and lethality, and decreasing acoustic signature of the projectile down range. | ||||||

The bottom cam surface and the top cam surface extend from the front end toward the chamber end of the barrel and each have undulating surfaces that moves against the lower cam follower surfaces of the slide to cause oscillation of the barrel while the slide moves during the firing sequence. | ||||||
