Lightweight gas combustion gun (CLGG) is a projectile weapon utilizing the explosive force of a low molecular weight flammable gas, such as hydrogen mixed with oxygen, as a propellant. When the gas is ignited, they burn, expand and push the projectile out of the barrel with higher efficiency relative to solid propellant and have reached higher muzzle velocity in the experiment. The technology of combustion gas firearms is one area that is explored in an effort to reach higher speeds of artillery to gain greater reach. Conventional weapons use solid propellant, usually a nitrocellulose-based compound, to develop the space pressures required to accelerate projectiles. The CLGGs gas propellant is capable of enhancing propellant specific impulses. Therefore, hydrogen is usually the first choice; However, other propellants such as methane may be used.
While this technology appears to provide higher speeds, a major drawback with gas or liquid propellants for weapon systems is the difficulty in obtaining uniform and predictable ignition and velocity. Variance with muzzle velocity affects precision within range, and the further a gun shoot, the more significant this variation. If the artillery system can not maintain a uniform and predictable muzzle velocity, it will be of no use in longer ranges. Another problem is the survival of projectile loads at higher accelerations. Fuzes, explosives, and guidance systems must all "harden" against significant accelerated loads of conventional artillery to survive and function properly. Higher-speed weapons, such as CLGG, face this engineering challenge because they transcend the limits of higher acceleration spins.
The research and development company UTRON, Inc. is experimenting with the design of lightweight combustion gas guns for use in the field. The corporation claims to have a system ready to be tested as a potential naval naval support weapon for newly emerging ships, such as the Zumwalt class destroyer. CLGG, like the railgun, is a likely candidate technology for a larger range for naval systems, among others. UTRON has built and tested light combustion gases 45mm and 155mm.
