The size and shape of the muzzle flash is dependent on the combustion energy of propellant being used, the amount of combustible ejecta remaining, and any devices attached to the muzzle. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. The gun consists of three tubes: the expansion, pump, and launch tubes. 2. These types of guns are also called hypervelocity guns since the projectile travels at more than Mach 5 (1500 m/s at sea level). 2 2H. UTRON has built and tested 45mm and 155mm combustion light gas guns. The velocity of a 40-gram (a cylindrical slug of minimum practical weight) projectile would be 14,000 ft/sec at the maximum chamber design pressure of 60,000 psi. This is an important, but not the only, factor affecting theperformance of a fuel. The main difference is constituted by the means of achieving the necessary pressure to accelerate the projectile. A railgun is a device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. Variance with muzzle velocities affects precision in range, and the further a weapon shoots, the more significant these variances become. The projectile normally does not contain explosives, instead relying on the projectile's high speed and kinetic energy to inflict damage. The Combustion Light Gas Gun, or CLGG, has been investigated for over ten years. 6349 - The Combustion Light Gas Gun: A novel yet proven high velocity technology, Mr. David Kruczynski, UTRON, Inc. Fuel Cells for Munitions, Mr. Edgar Seydel, Th e Ashlawn Group 6332 - Plasma-Enchanced Magnetron Technology for Durable Pollution-Free Coatings, Dr. Sabrina Lee , … A projectile is any object thrown by the exertion of a force. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. The \"heat of combustion\" of a fuelis a measure of the amount of energyreleased when the fuel isburned. The expansion piston in turn drives the pump piston housed within the pump tube by means of a rod connecting the two pistons. Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to 1,700 m/s (5,600 ft/s) for tank guns firing kinetic energy penetrator ammunition. [1] The corporation claims to have a system ready for testing as a potential long-range naval fire support weapon for emerging ships, such as the Zumwalt-class destroyer. Fuses, explosive fill, and guidance systems all must be "hardened" against the significant acceleration loads of conventional artillery to survive and function properly. What caught my attention however are combustion light-gas guns. Although any object in motion through space may be called a projectile, the term more commonly refers to a ranged weapon. In the anti-tank role, as tank armor improved during World War II newer designs began to use a smaller but dense penetrating body within a larger shell. An example of the CLGG’s potential can be seen in Table 1 which shows predicted performance for CLGG based launchers as a function of tube length. Another issue is the survival of projectile payloads at higher accelerations. An improved two-stage light gas gun for launching projectiles at high speeds.

Another light gas gun, the Combustion Light Gas Gun in a 155 mm prototype form was projected to achieve 2500 m/s with A gun barrel is a crucial part of gun-type ranged weapons such as small firearms, artillery pieces and air guns. 2 + O. A combustion light-gas gun (CLGG) is a projectile weapon that utilizes the explosive force of low molecular-weight combustible gases, such as hydrogen mixed with oxygen, as propellant. In an airgun, the large piston is powered by a spring or compressed air, and the working fluid is atmospheric air. From the 1860s to 1950s, a major application of armor-piercing projectiles was to defeat the thick armor carried on many warships. The main problem with a light-gas gun is that you need a supply of both gunpowder to drive the piston and the light gas (hydrogen or helium) to … Mathematical equations of motion are used to analyze projectile trajectories. When the gases are ignited, they burn, expand and propel the projectile out of the barrel with higher efficiency relative to solid propellant and have achieved higher muzzle velocities in experiments. The CLGG, like the railgun, is a possible candidate technology for greater ranges for naval systems, among others. The gun (based on a design at Ernst Mach Institute) has a 100‐mm diameter by 7.6 long pump tube and a 50‐mm diameter by 7.6‐m long launch tube. A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. While this technology does appear to provide higher velocities, the main drawback with gaseous or liquid propellants for gun systems is the difficulty in getting uniform and predictable ignition and muzzle velocities. The gun is a ranged weapon typically designed to pneumatically discharge solid projectiles but can also be liquid or even charged particles and may be free-flying or tethered. A dynamite gun is any of a class of artillery pieces that use compressed air to propel an explosive projectile. Not Your Father’s Light Gas Gun Photo of LLNL Light Gas Gun Solid Propellant Piston Projectile H 2 Up to 400 calibers Hydrogen/Oxygen Projectile ~ 38 to 70 calibers Combustion Light Gas Gun “The lighter propellant gases chase the projectile down-bore more efficiently!” The combustion light gas gun (CLGG) uses a low molecular weight gas as the propellant to burn, expand and propel the projectile out of the barrel with higher muzzle velocities. Higher velocity weapons, like the CLGG, face these engineering challenges as they edge the boundaries of firing accelerations higher. CLGGs' gaseous propellants are able to increase the propellant's specific impulse. The research and development firm UTRON, Inc is experimenting with a combustion light-gas gun design for field use. It is thought to be possible to achieve non-rocket spacelaunch with this technology. Muzzle velocity is the speed of a projectile with respect to the muzzle at the moment it leaves the end of a gun's barrel.

A combustion light gas gun (CLGG) uses low molecular weight gas, such as hydrogen mixed with oxygen, as propellant. AP rounds smaller than 20 mm are typically known as "armor-piercing ammunition", and are intended for lightly-armored targets such as body armor, bulletproof glass and light armored vehicles. A combustion light gas gun (CLGG) is a projectile weapon that utilizes the explosive force of low molecular-weight combustible gases, such as hydrogen mixed with oxygen, as propellant. Another issue is the survival of projectile payloads at higher accelerations. The knowledge of material properties involved in impact situations is critical in different technological areas in order to guarantee safe operations. While this technology does appear to provide higher velocities, the main drawback with gaseous or liquid propellants for gun systems is the difficulty in getting uniform and predictable ignition and muzzle velocities. Anti-aircraft guns can also be mounted to tanks. Combustion Gun: Light weight, Portable, Cheap, Reusable, Easy to make, World's first most light weight and transparent yet powerful gun ! When the propellant is ignited, the higher pressure gases are bled out through vents at reduced pressure to a much larger low pressure chamber to push the projectile forward. UTRON has built and tested 45mm and 155mm combustion light-gas guns. This reduction in diameter acts as a lever, increasing the speed while decreasing the force. As shown in Figure 5, the CLGG consists, in its simplest configuration, of a chamber sealed with a diaphragm and filled with a combustible mix of light gaseous propellants such as methane, hydrogen, oxygen, and helium, in various combinations. As a conventional gun utilizes the combustion of a prop… From the 1920s onwards, armor-piercing weapons were required for anti-tank missions. C. Light Gas Guns []. Ballistics is the field of mechanics concerned with the launching, flight behavior and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. Dynamite guns were in use for a brief period from the 1880s to the beginning of the twentieth century. Modern tank guns are large-caliber high-velocity guns, capable of firing kinetic energy penetrators, high explosive anti-tank rounds, and in some cases guided missiles. It has a far more efficient use of the propellant, unlike earlier recoilless weapons, where most of the propellant is expended to the rear of the weapon to counter the recoil of the projectile being fired. Common propellants are energetic materials and consist of a fuel like gasoline, jet fuel, rocket fuel, and an oxidizer. 7741 - Super 40mm High Explosive Air Burst - Shaping the Future, Mrs. Kara Sims, General Dynamics - OTS An experimental light-gas gun should operate in a similar way to a conventional gun with powder. 2H. Learn how and when to remove this template message. The initial Range G configuration was a 2.5-inch bore, two-stage, light-gas gun firing into a 10-foot-diameter test tank 1,000-feet in length. It enables a much larger projectile to be launched without the heavy equipment typically required for large caliber weapons. A large-diameter piston is used to force a gaseous working fluid through a smaller-diameter barrel containing the projectile to be accelerated. Why are my soldiers weapons so ineffective, or the rarity of one-hit kills. The gases are ignited, burn, expand and propel the projectile out of the barrel with higher efficiency relative to solid propellant and have achieved higher muzzle velocities in experiments.
