5,000 V/m, B > 2 T), and surface temperatures of > 800 deg C. The package should be able to operate in the presence of any plasma that may form in the bore or at the muzzle exit and must also be radiation hardened due to exo-atmospheric flight. {\displaystyle d} 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. Abstract:Results obtained with the HELEOS (hypervelocity experimental launcher for equation of state) railgun, which uses a two-stage light-gas gun (2SLGG) as an injector, are presented. In some hypervelocity research projects, projectiles are 'pre-injected' into railguns, to avoid the need for a standing start, and both two-stage light-gas guns and conventional powder guns have been used for this role. [10][11] During World War I, the Director of Inventions at the Ministry of Armaments, Jules-Louis Brenton, commissioned Fauchon-Villeplee to develop a 30-mm to 50-mm electric cannon on July 25, 1918 after delegates from the Commission des Inventions witnessed test trials of the working model in 1917. The Yugoslavian Military Technology Institute developed, within a project named EDO-0, a railgun with 7 kJ kinetic energy, in 1985. A single destroyer carries 4 gas turbine engines that are each capable of 40,000+ shaft horsepower. Under high-use conditions, current railguns would require frequent replacement of the rails, or to use a heat-resistant material that would be conductive enough to produce the same effect. Plasma railguns are used in physics research and they have been explored as a potential trigger mechanism of magneto-inertial fusion. For space launches from Earth, relatively short acceleration distances (less than a few km) would require very strong acceleration forces, higher than humans can tolerate. Note that The light-gas gun is an apparatus for physics experiments. [UPDATED April 8 with more rail gun & laser detail from Rear Adm. Klunder] NATIONAL HARBOUR: 23 pounds ain’t heavy. In studies concerned with high pressures, the possibility of a utilization of electromagnetic railgun accelerators has been considered, because the railgun will be able to achieve an impact velocity of 10-20 km/s, which is not attainable when a conventional two-stage light gas gun is employed.

In addition, railgun systems have shown to potentially provide higher velocity of projectiles, which would increase accuracy for anti-tank, artillery, and air defense by decreasing the time it takes for the projectile to reach its target destination. Further multi-acceleration experiments using two railguns connected in series are in preparation. This section presents some elementary analysis of the fundamental theoretical electromagnetic principles that govern the mechanics of railguns. (Lets just say cruise missiles and large 350mm rail-gun both firing on a frigate, with about even skills on tracking and nothing else equipped on the ship or help aim) Missiles would be better, but to an extent. However, at the time the weapon was introduced, railguns are still considered to be prototype phase and due to a myriad of issues, such as power generation and heat dissipation are limited in size and portability to fixed (usually naval) … One of the major projects in railgun research that ARL was involved in was the Cannon-Caliber Electromagnetic Gun (CCEMG) program, which took place at the Center for Electromechanics at the University of Texas (UT-CEM) and was sponsored by the U.S. Marine Corps and the U.S. Army Armament Research Development and Engineering Center. In the Navy's next-generation battleship, the all-electric DD(X), producing this kind of current will be possible. A railgun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. The goal, according to Tom Beutner, head of Naval Air Warfare and Weapons for the ONR, is ten shots per minute at 32 megajoules. Then near the middle of Railgun (the Level Upper Arc), the events and timeline start to converge with Index.. For an example, in episode 17 of the Railgun anime, Komoe-sensei mentions how she likes all her students, even the ones that blow up her roof, which is probably a reference to when Index used Dragon's Breath (episode 6 of Index). [58], BAE Systems was at one point interested in installing railguns on their Future Combat Systems Manned Ground Vehicles. The projectile is energized continuously by two brushes sliding along the rails, and two or more additional brushes on the projectile serve to energize and commute several windings of the helical barrel direction in front of and/or behind the projectile. d It is one of several United States Government efforts to develop plasma-based projectiles. t The ARC-920 railgun is a result of scientific breakthroughs following the Human-Covenant War that allowed for portable, hand-held, electromagnetic launcher systems to be used in combat. {\displaystyle L'} + If the railway is lost the gun cannot move but it can still fire. Skip to content. The projectile normally does not contain explosives, instead relying on the projectile's high speed, mass, and kinetic energy to inflict damage. [citation needed] Russia,[64] China,[65][66] and Turkey's defence company ASELSAN [67] are also developing railguns.[68].

As briefly discussed above, the stresses involved in firing this sort of device require an extremely heat-resistant material. {\displaystyle x=-\infty } I have owned a Paslode in the past and now have a DeWalt cordless gun. IIRC some research railguns use pre-injection, either by conventional explosive propellant or by light gas gun. Teaming the Railgun with some infantry will improve its' surviveability against air attacks or close assaults. ... this paper presents a unique two-stage light-gas gun capable of replicating hypervelocity impacts. Hunting. As rail/projectile clearances increase, arcing develops, which causes rapid vaporization and extensive damage to the rail surfaces and the insulator surfaces. > I With most practical railgun geometries, it is not easy to produce an electromagnetic expression for the railgun force that is both simple and reasonably accurate. The speed, cost, and numerical advantages of railgun systems may allow them to replace several different systems in the current layered defense approach. In July, 2017, Defensetech reported that the Navy wants to push the Office of Naval Research's prototype railgun from a science experiment into useful weapon territory. [112] According to a CNBC report from U.S. intelligence, China's railgun system was first revealed in 2011, and ground testing began in 2014. That depends on the size and speed of the projectile, but for a large railgun the sound will be very similar to that of a conventional gun. [92], Though the 23 lb projectiles have no explosives, their Mach 7 velocity gives them 32 megajoules of energy, but impact kinetic energy downrange will typically be 50 percent or less of the muzzle energy.   accelerating the projectile would be given by the formula:[3]. The rails need to withstand enormous repulsive forces during shooting, and these forces will tend to push them apart and away from the projectile. {\displaystyle I^{2}R'x} Thus far, the project is self-funded. The Navy is also developing directed-energy weapons for air defense use, but it will be years or decades before they will be effective. This causes three main problems: melting of equipment, decreased safety of personnel, and detection by enemy forces due to increased infrared signature. There’s a lot happening in the world of A Certain Scientific Railgun and A Certain Magical Index, so we wanted to help out.   and energy lost via electrical resistance heating of the rails (and armature). electromagnetic railgun’s (EMRG) power supply, thus reducing its footprint. Increased muzzle velocities with better aerodynamically streamlined projectiles can convey the benefits of increased firing ranges while, in terms of target effects, increased terminal velocities can allow the use of kinetic energy rounds incorporating hit-to-kill guidance, as replacements for explosive shells. The first weaponized railgun planned for production, the General Atomics Blitzer system, began full system testing in September 2010. Two Railguns can be seen in the back of the TM-02 Khanjali. μ A relatively common variant of this configuration is the augmented railgun in which the driving current is channelled through additional pairs of parallel conductors, arranged to increase ('augment') the magnetic field experienced by the moving armature. {\displaystyle s} That plays a huge role. It was the first time in history that such levels of performance were reached. − Railgun performance with a two-stage light-gas gun injector.   term will be zero. [101] In 1991, they determined the properties required for developing an effective launch package as well as the design criteria necessary for a railgun to incorporate finned, long rod projectiles. [47], Railguns are being researched as weapons with projectiles that do not contain explosives or propellants, but are given extremely high velocities: 2,500 m/s (8,200 ft/s) (approximately Mach 7 at sea level) or more. [110][109][111], China is developing its own railgun system. [59][60][61] This program was the US Army's third attempt to replace the aging M2 Bradley. Light your charcol grill in seconds with this high powered propane torch or sear your meat with Su-VGun! [8] For potential military applications, railguns are usually of interest because they can achieve much greater muzzle velocities than guns powered by conventional chemical propellants. Tests of a 30 mm version are planned to be conducted. {\displaystyle s} {\displaystyle L'}  ) between the point where the force ( Research on railgun technology served as a major area of focus at the Ballistic Research Laboratory (BRL) throughout the 1980s. F A railgun consists of two parallel metal rails (hence the name). d [3], As of 2020, railguns have been researched as weapons utilising electromagnetic forces to impart a very high kinetic energy to a projectile (e.g. Astrophysical Observatory.

The total launch package would weigh almost 1.4 tons. Conventional artillery munitions use either explosive or amour piercing explosive projectiles. {\displaystyle {\widehat {z}}} The facility also provided a power system that included thirteen 1- MJ capacitor banks, an assortment of electromagnetic launcher devices and diagnostic apparatuses. How the superweapon China may be building works", "Is China Getting Ready to Test a Railgun? Con: You need two accessories (battery and fuel cell) to power the tool. The power source is a non-issue. It should also be able to survive accelerations of at least 20,000 g (threshold) / 40,000 g (objective) in all axes, high electromagnetic fields (E > 5,000 V/m, B > 2 T), and surface temperatures of > 800 deg C. The package should be able to operate in the presence of any plasma that may form in the bore or at the muzzle exit and must also be radiation hardened due to exo-atmospheric flight. {\displaystyle d} 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. Abstract:Results obtained with the HELEOS (hypervelocity experimental launcher for equation of state) railgun, which uses a two-stage light-gas gun (2SLGG) as an injector, are presented. In some hypervelocity research projects, projectiles are 'pre-injected' into railguns, to avoid the need for a standing start, and both two-stage light-gas guns and conventional powder guns have been used for this role. [10][11] During World War I, the Director of Inventions at the Ministry of Armaments, Jules-Louis Brenton, commissioned Fauchon-Villeplee to develop a 30-mm to 50-mm electric cannon on July 25, 1918 after delegates from the Commission des Inventions witnessed test trials of the working model in 1917. The Yugoslavian Military Technology Institute developed, within a project named EDO-0, a railgun with 7 kJ kinetic energy, in 1985. A single destroyer carries 4 gas turbine engines that are each capable of 40,000+ shaft horsepower. Under high-use conditions, current railguns would require frequent replacement of the rails, or to use a heat-resistant material that would be conductive enough to produce the same effect. Plasma railguns are used in physics research and they have been explored as a potential trigger mechanism of magneto-inertial fusion. For space launches from Earth, relatively short acceleration distances (less than a few km) would require very strong acceleration forces, higher than humans can tolerate. Note that The light-gas gun is an apparatus for physics experiments. [UPDATED April 8 with more rail gun & laser detail from Rear Adm. Klunder] NATIONAL HARBOUR: 23 pounds ain’t heavy. In studies concerned with high pressures, the possibility of a utilization of electromagnetic railgun accelerators has been considered, because the railgun will be able to achieve an impact velocity of 10-20 km/s, which is not attainable when a conventional two-stage light gas gun is employed.

In addition, railgun systems have shown to potentially provide higher velocity of projectiles, which would increase accuracy for anti-tank, artillery, and air defense by decreasing the time it takes for the projectile to reach its target destination. Further multi-acceleration experiments using two railguns connected in series are in preparation. This section presents some elementary analysis of the fundamental theoretical electromagnetic principles that govern the mechanics of railguns. (Lets just say cruise missiles and large 350mm rail-gun both firing on a frigate, with about even skills on tracking and nothing else equipped on the ship or help aim) Missiles would be better, but to an extent. However, at the time the weapon was introduced, railguns are still considered to be prototype phase and due to a myriad of issues, such as power generation and heat dissipation are limited in size and portability to fixed (usually naval) … One of the major projects in railgun research that ARL was involved in was the Cannon-Caliber Electromagnetic Gun (CCEMG) program, which took place at the Center for Electromechanics at the University of Texas (UT-CEM) and was sponsored by the U.S. Marine Corps and the U.S. Army Armament Research Development and Engineering Center. In the Navy's next-generation battleship, the all-electric DD(X), producing this kind of current will be possible. A railgun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. The goal, according to Tom Beutner, head of Naval Air Warfare and Weapons for the ONR, is ten shots per minute at 32 megajoules. Then near the middle of Railgun (the Level Upper Arc), the events and timeline start to converge with Index.. For an example, in episode 17 of the Railgun anime, Komoe-sensei mentions how she likes all her students, even the ones that blow up her roof, which is probably a reference to when Index used Dragon's Breath (episode 6 of Index). [58], BAE Systems was at one point interested in installing railguns on their Future Combat Systems Manned Ground Vehicles. The projectile is energized continuously by two brushes sliding along the rails, and two or more additional brushes on the projectile serve to energize and commute several windings of the helical barrel direction in front of and/or behind the projectile. d It is one of several United States Government efforts to develop plasma-based projectiles. t The ARC-920 railgun is a result of scientific breakthroughs following the Human-Covenant War that allowed for portable, hand-held, electromagnetic launcher systems to be used in combat. {\displaystyle L'} + If the railway is lost the gun cannot move but it can still fire. Skip to content. The projectile normally does not contain explosives, instead relying on the projectile's high speed, mass, and kinetic energy to inflict damage. [citation needed] Russia,[64] China,[65][66] and Turkey's defence company ASELSAN [67] are also developing railguns.[68]. Railgun combined with two-stage light gas guns, this effect results in intense heat up to 7. Conductive metal, such as copper railgun ’ s gun bodes well for the future of weaponry 61 this.
