[47] There would be a peak operating magnetic field of 5 T—half of this coming from the rails, and the other half from augmenting magnets. 2 [29] Featuring a 30-mm roundbore, the launcher was capable of firing three, five-round salvos of 185-g launch packages at a muzzle velocity of 1850 m/s and a firing rate of 5 Hz. d x {\displaystyle v} Currently different rail shapes and railgun configurations are being tested, most notably by the U.S. Navy (Naval Research Laboratory), the Institute for Advanced Technology at the University of Texas at Austin, and BAE Systems. x During the early 1990s, the U.S. Army dedicated more than $150 million into electric gun research. ′ [73] Satellite imagery in late 2010 suggested that tests were being conducted at an armor and artillery range near Baotou, in the Inner Mongolia Autonomous Region.[74]. ) by a factor of about 3 or 4 ( To illustrate the principles involved, it can be useful to consider the rails and the armature as thin wires or "filaments". {\displaystyle F} ... this paper presents a unique two-stage light-gas gun capable of replicating hypervelocity impacts. 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. By Joe Genzel. China Just Blew The US Navy’s Electromagnetic Railgun Out Of The Water. [104] As part of the CCEMG program, UT-CEM designed and developed the Cannon-Caliber Electromagnetic Launcher, a rapid-fire railgun launcher, in 1995. Total power consumption must be less than 8 watts (threshold)/5 watts (objective) and the battery life must be at least 5 minutes (from initial launch) to enable operation during the entire engagement. Here’s a look at the pros and cons of each operating system. At one end, these rails are connected to an electrical power supply, to form the breech end of the gun. The first computer simulations occurred in 1990, and its first published experiment appeared on August 1, 1993. Use, Smithsonian This provides you with a lighter, more controlled feel and great balance. Hunting. 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. This automatically increases the force. Some high velocity projectiles developed by the Navy have command guidance, but the accuracy of the command guidance is not known, nor even if it can survive a full power shot. When using the Railgun during Beast vs. Slasher, the lights on the gun will not be turned on until the power is restored. All modern production 1911s use some form of added parts or lightweight parts+stronger springs to reduce the chance of a AD if the pistol is dropped compared to classic 1911s. The guns were to be mounted in batteries of six firing twelve rounds per minute, and it was to fit existing 12.8 cm FlaK 40 mounts. is the perpendicular distance from the point on the armature to the axis of one of the wires. It's generation capacity that's more of an issue, but even that just … [53] During one of the tests, the projectile was able to travel an additional 7 kilometres (4.3 mi) downrange after penetrating a 1⁄8 inch (3.2 mm) thick steel plate. x [13], In 1923, Russian scientist A. L. Korol’kov detailed his criticisms of Fauchon-Villeplee's design, arguing against some of the claims that Fauchon-Villeplee made about the advantages of his invention. Melting: The high velocity of the armature and the heat caused by resistive heating damages the surface of the rails. [24][26], Since 1993 the British and American governments have collaborated on a railgun project at the Dundrennan Weapons Testing Centre that culminated in the 2010 test where BAE Systems fired a 3.2 kg (7 pound) projectile at 18.4-megajoules [3,390 m/s (7,600 mph; 12,200 km/h; 11,100 ft/s)]. [UPDATED April 8 with more rail gun & laser detail from Rear Adm. Klunder] NATIONAL HARBOUR: 23 pounds ain’t heavy. d However, the Zumwalt has been cancelled and no further units will be built. Despite the ARC-920's lighter weight over previous models, it is still too heavy and cumbersome for general use by non-augmentedpersonnel. The colt series 80 and after guns have a firing pin safety block. The rails and projectiles must be built from strong conductive materials; the rails need to survive the violence of an accelerating projectile, and heating due to the large currents and friction involved. v By passing current through busbars and projectile, a force is induced which propels the projectile along the bus-bars and into flight. The ARC-920 uses a pair of parallel conducti… {\displaystyle {\boldsymbol {\ell }}} {\displaystyle F} The above formula is based on the assumption that the distance ( {\displaystyle d} It is worth noting that the Tek Railgun cannot be fired underwater, whereas the Tek Riflecan be. A very large power supply, providing on the order of one million amperes of current, will create a tremendous force on the projectile, accelerating it to a speed of many kilometres per second (km/s). Attention is given to the principle of railgun operation, the use of a railgun for equation of state (EOS) research, and a segmented multistage railgun. [7] A plasma armature is formed by an arc of ionised gas that is used to push a solid, non-conducting payload in a similar manner to the propellant gas pressure in a conventional gun. This timeframe suggests the weapons are planned to be installed on the Navy's next-generation surface combatants, expected to start construction by 2028. ) from the end of the wire is given by[37]. 2 CRS Report R41526, Navy Shipboard Lasers for Surface, Air, and Missile Defense: Background and Issues for Congress, by Ronald O'Rourke. ^ It is one of several United States Government efforts to develop plasma-based projectiles. ... Half of a Gun, and a Life Lesson, On Christmas Morning. It is a highly specialized gun designed to generate extremely high velocities. [27][31][failed verification] They gave the project the motto "Velocitas Eradico", Latin for "I, [who am] speed, eradicate"—or in the vernacular, "Speed Kills". According to those working on it, with other modifications it was able to achieve a speed of 4,500 m/s (14,800 ft/s). ℓ [116][117], In November 2017, India's Defence Research and Development Organisation carried out a successful test of a 12 mm square bore electromagnetic railgun. The light-gas gun is an apparatus for physics experiments. x {\displaystyle L'} And, it was an eye opening, kick in the teeth experience—which amplified my areas of weakness as a shooter. This causes three main problems: melting of equipment, decreased safety of personnel, and detection by enemy forces due to increased infrared signature. "[50], Current railgun technologies necessitate a long and heavy barrel, but a railgun's ballistics far outperform conventional cannons of equal barrel lengths. Railguns have limited potential to be used against both surface and airborne targets. ), the radius of the rails (which are assumed to be circular in cross section) ( There are more powerful … {\displaystyle VI} The power source is a non-issue. 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. [62][63], India has successfully tested their own railgun. [96] The Navy may eventually enhance railgun technology to enable it to fire at a range of 200 nmi (230 mi; 370 km) and impact with 64 megajoules of energy. Each machine would have a 3.3-ton carbon fibre rotor spinning at high speeds. In order to be affordable, the production cost per projectile must be as low as possible, with a goal of less than $1,000 per unit. This weapon can fire a projectile at tremendous speeds without even using an expanding gas. [18][19] Topics of research included plasma dynamics,[20] electromagnetic fields,[21] telemetry,[22] and current and heat transport. A 32 megajoule railgun shot is equivalent to about 23,600,000 foot-pounds, so a single 32 MJ shot has the same muzzle energy as about 200,000 .22 rounds being fired simultaneously. assuming the rails are lying in the xy plane and run from x = 0 back to Or, apparently, by electrically exploding a thin nichrome wire and disk of aluminum foil. But ionizing gas into plasma isn’t too uncommon,” he says. That plays a huge role. + If the railway is lost the gun cannot move but it can still fire. This decreases ammunition size and weight, allowing more ammunition to be carried and eliminating the hazards of carrying explosives or propellants in a tank or naval weapons platform. Such a development would then convey a further military advantage in that the elimination of explosives from any military weapons platform will decrease its vulnerability to enemy fire. d Rail and insulator wear problems still need to be solved before railguns can start to replace conventional weapons. 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). So, if the armature connects the ends of two such semi-infinite wires separated by a distance, Additionally, projectiles can be subject to some degree of ablation, and this can limit railgun life, in some cases severely.[43]. Then, if a conductive projectile is inserted between the rails (e.g. Le principe. The Tek Railgun fires explosive plasma blasts. Photo by Chris Polley. As briefly discussed above, the stresses involved in firing this sort of device require an extremely heat-resistant material. I [17], In 1980, the Ballistic Research Laboratory (later consolidated to form the U.S. Army Research Laboratory) began a long-term program of theoretical and experimental research on railguns. This creates a repulsive force, proportional to the current, that attempts to push the rails apart. Here the force, current and field are all treated as vectors, so the above vector cross product gives a force directed along the bore axis, acting on the current in the armature, as a consequence of the magnetic field. During the first year of the Galactic Empire's reign, Jocasta Nu wielded one such rifle against Darth Vader. behind the armature. and the above voltage and current terms can be placed into appropriate circuit equations to determine the time variation of current and voltage. x Some railguns also use strong neodymium magnets with the field perpendicular to the current flow to increase the force on the projectile. [13], During 1950, Sir Mark Oliphant, an Australian physicist and first director of the Research School of Physical Sciences at the new Australian National University, initiated the design and construction of the world's largest (500 megajoule) homopolar generator. Solid armatures may also 'transition' into hybrid armatures, typically after a particular velocity threshold is exceeded. Possible applications of the railgun include the study of high pressure phase transition of hydrogen and impact fusion research. Don’t hesitate to download the file and check out every bit of it, there’s a lot of […] The rails need to survive this without bending and must be very securely mounted. Korol’kov eventually concluded that while the construction of a long-range electric gun was within the realm of possibility, the practical application of Fauchon-Villeplee's railgun was hindered by its enormous electric energy consumption and its need for a special electric generator of considerable capacity to power it. and the square of the current, They can range from four to 30 feet (9 meters) long. This presents problems for a traditional battleship because power cannot be diverted from the ship's propulsion system. India aims to fire a one kilogram projectile at a velocity of more than 2,000 meters per second using a capacitor bank of 10 megajoules.[118]. ) as described below. as suggested above. A railgun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. ′ (or is it just me...), Smithsonian Privacy Repulsion: The current in each rail of a rail gun runs in opposite directions. While similar in energy to the aforementioned test, the railgun used is considerably more compact, with a more conventional looking barrel. The use of a railgun accelerator makes it possible to perform experiments involving a dynamic pressure of up … In these models the railgun is modeled on an electrical circuit and the driving force can be determined from the energy flow in the circuit. One such rifle was kept secure in the Jedi Archives. , oriented at right angles to both the armature and the bore axis, then, with an armature current 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. between the rails is The DeWalt is much better in the cold, no cleaning, similar weight. A railgun consists of two parallel metal rails (hence the name). ′ A railgun requires a pulsed DC power supply. Assuming that the many technical challenges facing fieldable railguns are overcome, including issues like railgun projectile guidance, rail endurance, and combat survivability and reliability of the electrical power supply, the increased launch velocities of railguns may provide advantages over more conventional guns for a variety of offensive and defensive scenarios. Watch the U.S. Navy Test Fire Its Much Touted Railgun The service wants the electromagnetic cannons in action by 2025, but power, cooling and just finding space on board ships are major challenges. 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. {\displaystyle I} L [98][99][100] In 1984, BRL researchers devised a technique to analyze the residue left behind on the bore surface after a shot was fired in order to investigate the cause of the bore's progressive degradation. , a fairly good approximation assuming the length of the wires is much larger than than this. The weapon system was successfully mounted on a Chinese Navy ship in December 2017, with sea trials happening later. / and an armature length Electrodynamic assistance to launch rockets has been studied. [33][34] No practical railgun weapon has been developed or is expected in the near-future as of January 2020[update]. The CCEMG railgun included several features: ceramic sidewalls, directional preloading, and liquid cooling. Even if conventional defense systems react fast enough, they are expensive and only a limited number of large interceptors can be carried. V . [58], BAE Systems was at one point interested in installing railguns on their Future Combat Systems Manned Ground Vehicles. Toaru Kagaku no Railgun (とある科学の 超電磁砲 (レールガン) , Toaru Kagaku no Rērugan? 2 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). is the all-important projectile velocity, The helical railgun is a cross between a railgun and a coilgun. ′ Two Railguns can be seen in the back of the TM-02 Khanjali. 2 Grillblazer GrillGun and Su-VGun Store. It follows that, where A hybrid armature uses a pair of plasma contacts to interface a metallic armature to the gun rails. + the infantry can buy time for the gun to run away should it be needed. Which is better in terms of a large battleship vs a frigate. The weapon launches a streamlined discarding sabot round designed by Boeing's Phantom Works at 1,600 m/s (5,200 ft/s) (approximately Mach 5) with accelerations exceeding 60,000 gn. [113], In early February 2018, pictures of what is claimed to be a Chinese railgun were published online. 1 Railgun is also spelled as rail gun; EMRG is also abbreviated as EM railgun. Once a lightsaber was properly loaded into an open slot on top of the rifle, a lightsaber rifle could produce an overwhelmingly powerful and destructive beam of energy. s There are also Lorentz forces acting on the rails and attempting to push them apart, but since the rails are mounted firmly, they cannot move. [83], In 2014 the U.S. Navy had plans to integrate a railgun that has a range of over 16 km (10 mi) onto a ship by 2016. [39][40][41][42] The rails also repel themselves via a sideways force caused by the rails being pushed by the magnetic field, just as the projectile is. [106], In 1999, a collaboration between ARL and IAT led to the development of a radiometric method of measuring the temperature distribution of railgun armatures during a pulsed electrical discharge without disturbing the magnetic field. The Navy is also developing directed-energy weapons for air defense use, but it will be years or decades before they will be effective. [107] In 2001, ARL became the first to obtain a set of accuracy data on electromagnetic gun-launched projectiles using jump tests. As a result, the U.S. military focused on developing small guided projectiles that could withstand the high-G launch from ultra-high velocity plasma armature railguns. Astrophysical Observatory. [79] It is expected to be ready between 2020 and 2025. In current designs massive amounts of heat are created by the electricity flowing through the rails, as well as by the friction of the projectile leaving the device. represents the electromagnetic work done. Payload per launch in these conditions is over 400 kg. 1,421,435 "Electric Apparatus for Propelling Projectiles". − This current makes the railgun behave as an electromagnet, creating a magnetic field inside the loop formed by the length of the rails up to the position of the armature. Note this is if the wire runs from the location of the armature e.g. Tests of a 30 mm version are planned to be conducted. Unless this is an elaborate and well-executed hoax, Smyth’s gun bodes well for the future of weaponry. Back in February, photos circulating on social media appeared to show a railgun-esque deck gun mounted on the bow of the Type 072III-class landing ship Haiyang Shan. Probably the oldest consistently successful system was built by the UK's Defence Research Agency at Dundrennan Range in Kirkcudbright, Scotland. [76] Nine megajoules is enough energy to deliver 2 kg (4.4 lb) of projectile at 3 km/s (1.9 mi/s)—at that velocity, a sufficiently long rod of tungsten or another dense metal could easily penetrate a tank, and potentially pass through it, (see APFSDS). More Guns. This shows that the force will be proportional to the product of {\displaystyle {\mathrm {d} I}/{\mathrm {d} t}} v The rails need to withstand enormous repulsive forces during shooting, and these forces will tend to push them apart and away from the projectile. Symposium on Electromagnetic Launch Technology (EML 2012) at Beijing. [105], The U.S. Army Research Laboratory also monitored electromagnetic and electrothermal gun technology development at the Institute for Advanced Technology (IAT) at the University of Texas at Austin, one of five university and industry laboratories that ARL federated to procure technical support. [80], A test of a railgun took place on December 10, 2010, by the U.S. Navy at the Naval Surface Warfare Center Dahlgren Division. ", "US Navy Ready to Deploy Laser for 1st Time", "The Navy Wants To Fire Its Ridiculously Strong Railgun From The Ocean", "Navy's new laser weapon: Hype or reality? Since the current is in the opposite direction along each rail, the net magnetic field between the rails (B) is directed at right angles to the plane formed by the central axes of the rails and the armature. While explosive-powered military guns cannot readily achieve a muzzle velocity of more than ≈2 km/s, railguns can readily exceed 3 km/s. It was about 3 meters long, consisting of 2 meters of accelerating coil and 1 meter of decelerating coil. [23] While military research into railgun technology in the United States ensued continuously in the following decades, the direction and focus that it took shifted dramatically with major changes in funding levels and the needs of different government agencies. This simple model predicts that exactly half of the electromagnetic work will be used to store energy in the magnetic field along the barrel, Railgun velocities generally fall within the range of those achievable by two-stage light-gas guns; however, the latter are generally only considered to be suitable for laboratory use, while railguns are judged to offer some potential prospects for development as military weapons. Proton is estimated at $5000/kg as of 2015. As the projectile travels along the barrel, the distance from the breech to the armature increases. Media suggests that the system is or soon will be ready for testing. Which would be better against a frigate: A railgun with 9km optimal range and 5km falloff (125mm Carbide Railgun I) firing antimatter charges or a blaster with 2km optimal range and 1km falloff (Regulated Light Ion Phase Cannon I) and a longer-range charge, like Iridium, Tungsten, or Iron? This basic configuration is formed by a single loop of current and thus requires high currents (e.g., of order one million amperes) to produce sufficient accelerations (and muzzle velocities). 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. It was the first time in history that such levels of performance were reached. It's generation capacity that's more of an issue, but even that just means "wait for a longer period of time between shots." L A supersonic sea-skimming anti-ship missile can appear over the horizon 20 miles from a warship, leaving a very short reaction time for a ship to intercept it. φ Thus far, the project is self-funded. Resistive losses now correspond to a power flow In late 80's I worked on a "Rail Gun Project" (but exactly it was a Gauss gun) for German Military. This section presents some elementary analysis of the fundamental theoretical electromagnetic principles that govern the mechanics of railguns. and energy lost via electrical resistance heating of the rails (and armature). Further multi-acceleration experiments using two railguns connected in series are in preparation. 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. Unless this is an elaborate and well-executed hoax, Smyth’s gun bodes well for the future of weaponry. [59][60][61] This program was the US Army's third attempt to replace the aging M2 Bradley. Watch the U.S. Navy Test Fire Its Much Touted Railgun The service wants the electromagnetic cannons in action by 2025, but power, cooling and just finding space on board ships are major challenges. For a similar projectile, the range of railguns may exceed that of conventional guns. So the total power flowing into the railgun is then simply the product 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. The voltage across the railgun breech is given by. There is no requirement on high accelerations (A railgun can operate at lower accelerations) and no limit on upper speed. However, the parts are not to expensive, but im not sure of how much it all came to as I built it at my school during DT lessons. Alternatively, very long rail systems may be used to reduce the required launch acceleration. Railgun. The inductance and resistance of the rails and power supply limit the efficiency of a railgun design. Railgun performance with a two-stage light-gas gun injector ... Electromagnetic accelerator (railgun): This is going to be awesome! L The Ultimate Guide to Tanning Wild Game Pelts and Hides. [91] The first shipboard tests was to be from a railgun installed on an Spearhead-class expeditionary fast transport (EPF), but this was later changed to land based testing. Gas-Powered Nailer Pros/Cons: Pro: Gas-powered cordless nailers tend to run longer between re-charging than their all-battery-powered counterparts. Engineers are working to derive technologies developed for the DDG-1000 series ships into a battery system so other warships can operate a railgun. Teaming the Railgun with some infantry will improve its' surviveability against air attacks or close assaults. ), the distance between the central axes of the rails ( Even if current ships, such as the Arleigh Burke-class destroyer, can be upgraded with enough electrical power to operate a railgun, the space taken up on the ships by the integration of an additional weapon system may force the removal of existing weapon systems to make room available. Bigler. Currently published material suggests that major advances in material science must be made before rails can be developed that allow railguns to fire more than a few full-power shots before replacement of the rails is required. Because the value of μ0 is small (4π×10−7 H/m) it follows that powerful railguns need large driving currents. 0 With this approximation, the magnitude of the force vector can be determined from a form of the Biot–Savart law and a result of the Lorentz force. For a more workable simple model, a useful alternative is to use a lumped circuit model, to describe the relationship between the driving current and the railgun force. A Gauss gun is a great demonstration for the law of conservation of energy -- and a handy way to get rid of those energy-wasting incandescent bulbs. , the total field from both wires at any point on the armature is: where 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. μ This power represents an energy flow into three main forms: kinetic energy in the projectile and armature, energy stored in the magnetic field, {\displaystyle l} This machine could be supplied by a dedicated generator. [24] In 1990, the U.S. Army collaborated with the University of Texas at Austin to establish the Institute for Advanced Technology (IAT), which focused on research involving solid and hybrid armatures, rail-armature interactions, and electromagnetic launcher materials. 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. IIRC some research railguns use pre-injection, either by conventional explosive propellant or by light gas gun. I prefer Colt over Springfield as well. It is a highly specialized gun designed to generate extremely high velocities. z l Chronologically, Railgun comes first. They do not currently exist in a practical, usable form. Some other simplifying assumptions have also been made; to describe the force more accurately, the geometry of the rails and the projectile must be considered. [28] In 1995, the Center for Electromagnetics at the University of Texas at Austin designed and developed a rapid-fire railgun launcher called the Cannon-Caliber Electromagnetic Gun. Any trade-off analysis between electromagnetic (EM) propulsion systems and chemical propellants for weapons applications must also factor in its durability, availability and economics, as well as the novelty, bulkiness, high energy demand and complexity of the pulsed power supplies that are needed for electromagnetic launcher systems. [114][115] In March 2018, it was reported that China confirmed it had begun testing its electromagnetic rail gun at sea. By definition, if a current of one ampere flows in a pair of ideal infinitely long parallel conductors that are separated by a distance of one meter, then the magnitude of the force on each meter of those conductors will be exactly 0.2 micro-newtons. In 1984, the formation of the Strategic Defense Initiative Organization caused research goals to shift toward establishing a constellation of satellites to intercept intercontinental ballistic missiles. [57] As is the case with the Phalanx CIWS, unguided railgun rounds will require multiple/many shots to bring down maneuvering supersonic anti-ship missiles, with the odds of hitting the missile improving dramatically the closer it gets.
