MARAUDER: Magnetically Accelerated Ring to Achieve Ultra-High Directed Energy and Radiation, TL: DR, an American project from the 1990's where they build a coaxial plasma railgun, which uses plasma as a KINETIC weapon, accelerating a Torus (a ring) of 0.5-2 milligrams of plasma to relativistic speeds, 1-3% the speed of light, 3000-10,000 km/s. Still not quite good enough for the satellite-based weapon that MARAUDER was meant to bebut pretty solid for ground-based combat. The PPRO1 Plasma Thermal Gun utilizes the electrothermal energy obtained from vaporizing a metallic material, creating a pressure wave of sufficient magnitude to cause a projectile to accelerate to ballistic velocities. It is worth noting that at that speed the projectile exceeds orbital velocity at Low Earth Orbit. Can my creature spell be countered if I cast a split second spell after it? Plasma is good against EVERYTHING - Hull AND shield - with big damage (with few exception), but since the travel time is slow, effective range is poor. In a plasma railgun, the armature and ejected projectile consist of hot, ionized, gas-like particles heated by a very high temperature. Episode about a group who book passage on a space ship controlled by an AI, who turns out to be a human who can't leave his ship? They are found as both ground emplacements and vehicle armaments. These weapons programs even look to be losing steam, especially when compared to the development of hypersonic missile technology. The trails are rugged and moderately steep, ascending from 480 feet of elevation to 900 feet in just the first third of a mile. The power requirement appears to be immense. Notice that the barrel length is much shorter than the dreadnaughts of WW1 fame. When Ruth died in 1973, Louise scattered her ashes on the preserve. MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. Plasma railguns are being evaluated for applications in magnetic confinement fusion for disruption mitigation and tokamak refueling. It may not display this or other websites correctly. Some features of this site may not work without it. If it breaks out by accident, even if it destroys everything would you still call it a 'weapon' ? T-shirts for the first 75 paid entrants, 15 years and up. Youve already signed up with this email address. There were some errors in the barrel length calculation for the earlier draft of this answer, which have since been corrected. http://www.navweaps.com/Weapons/WNUS_Rail_Gun.php. Unfortunately, George died in 1933 and Ruth returned to Boston in 1938 to set up a medical practice to support herself and her daughter. I remain unconvinced that the principle has any potential as a weapon that can compete against solid or explosive projectiles. What are the advantages of a coilgun v.s. What're the weight and dimensions of the slug? This answer (given technological development to improve power efficiency) meets all but two of your requirementsbut (potentially) bypasses their necessity. It is hoped that the work at the University of Texas described in these papers . There is, however, no theoretical limit to barrel length or muzzle velocity, so if you want >10km/s you almost certainly want a coilgun. What's wrong with accelerating a metal slug beyond its melting point? Fire rate will therefore be limited, and ultimate velocity will also be limited by your ability to a) quench your coils fast enough and b) cool them fast enough afterwards to fire the gun again. How many gs could a coilgun or railgun shell withstand? A chemical gun benefits from a longer barrel because the expanding gases have longer to do their thing. Also what kind of distance would these toroids be stable over? It only takes a minute to sign up. A 30mm projectile would let you fit your 100km/s gun into the original 100m length limit, but: You could use a fat, low-density sabot which drives a thin dense projectile, but the sabot represents parasitic weight that eats into the kinetic-energy budget of the narrow penetrator. Come enjoy the rolling countryside 4 mile course, we are now celebrating our 20th annual event! The Bulldog 4 is an annual fun run that also serves as a fundraiser for the Westmoreland PTA. Please enable JavaScript if possible. Coilguns don't have wear issues, as the projectile can be levitated in the barrel and be entirely non-contact and no arcing need occur. The Navy spent more than a . The glowing light is emitted by plasma.). Now THERE is a coil gun. | How could I contain plasma for use in weapons? You can enrol with friends and receive kits at your doorstep. Round is a solid KE penetrator. Designing plasma weapons that cannot pierce armour. Connect and share knowledge within a single location that is structured and easy to search. the railgun can launch projectiles much farther than the Additionally, a complex triple joint seal may exist at the breech of the bore, which can often pose an extreme engineering challenge. The plasma accelerator fires instantly, but the projectile is slow. How could you make a cat's tail prehensile enough to use weapons? TIL Project MARAUDER, a coaxial plasma railgun powered by the SHIVA STAR capacitor bank, was designed by the USAF and capable of " [producing] doughnut shaped rings of plasma and balls of lightning that exploded with devastating effects when hitting its target." It was classified in 1993. en.wikipedia.org 540 30 comments Add a Comment Which was the first Sci-Fi story to predict obnoxious "robo calls"? The plasma is accelerated until it leaves the muzzle of the railgun. The experiment which was performed to confirm the properties of the plasma jets produced by the coaxial plasma railgun is explained. This was the project's biggest issue. cheaper and more accurate than traditional gunpowder-based methods. | Summer Training Programs A coaxial railgun has one rail as a cylindrical shell encircling the other rail. The electrode strikes a plasma arc to the target, creating a conductive path and emptying the capacitor into the target. Want to develop practical skills on Mechanical? It seems like a really cool concept. Read how we use cookies and how you can control them by visiting our Privacy Policy. At least with the second approach, you can store your bullets normally. one report published just over a decade after, Marauder was the US militarys first plasma railgun and it might have worked. Can you still use Commanders Strike if the only attack available to forego is an attack against an ally? | Louise attended college, married and moved away. The Warwick Preserve was established when TNC received a 36-acre donation from Dr. Ruth Warwick and her daughter Louise Hunninen in 1964. Hand Held Coil Gun cannon - Enough to rip a giant robot limbs into pieces, Reimagined Weaponry: The Illidari Warglaives. You can assume that any figures this gives are over-optimistic, but it isn't a bad upper-bound for coilgun performance. And a plasma bolt with a lifespan of a millisecond, moving at 10,000km/s has a range of 10km. Learn more about Stack Overflow the company, and our products. Their design for plasma containment is called a Compact Toroid, and their design was similar to an arrangement called a Spheromak. Description. I'm pretty sure the plasma was preheated and injected into the railgun. MARAUDER took these Compact Toroids and fired them from a railgun.

Global sites represent either regional branches of The Nature Conservancy or local affiliates of The Nature Conservancy that are separate entities. It is noted that conventional plasma armature railguns are limited to velocities of 6-8 km/s by arc restrike. Charitable Solicitation Disclosures this region. That's a bit better, but remember: this is a maximum, regardless of anything else like barrel length, or field strength, or projectile weight. What does 'They're at four. Enter your email address and we will send you instructions to reset your password if there is an account for that email. Resources for Engineering Students | The intended use of this weapon is to have at least enough power to, Why don't we use the 7805 for car phone chargers? Naturally, in science fiction it would be very easy to explain that scientists discovered a more stable Toroidial configuration that lastswellhowever long you need it to last for the sake of the story. But the muzzle velocity is sqrt(2 * barrelLength * acceleration). Mechanical Kit will be shipped to you and you can learn and build using tutorials. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. While the preserve is worth visiting throughout the year, there are icy conditions on the steeper sections of the trail during the winter so make sure to bring appropriate gear or wait for the warmer seasons to enjoy the trails. The U.S. Air Force Research Laboratory must have made some significant progress in a short time, because computer simulations started in 1991, an experiment was conducted in 1993, and the whole thing was classified not long after. Glass, perhaps jacketed in something more durable like ceramic, could contain the plasma apparatus. Essentially its a still classified US military project aiming to develop a railgun capable of firing 0.5-2.0 mg toroids of plasma at up to 3% light speed. You must log in or register to reply here. The plasma railgun is a linear accelerator and plasma energy weapon which like a projectile railgun uses two long parallel electrodes to accelerate a sliding short armature. In 1993, the Air Force Research Laboratory finally published an experiment in high-velocity plasma projectile weapons. We use cookies to offer you a better browsing experience. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? The official Subreddit for the Isaac Arthur YouTube channel. A plasma railgun is a linear accelerator uses two long parallel electrodes to accelerate a "sliding short" armature. While most of New Hampshire tends to have acidic soils, the calcium-rich bedrock in Westmoreland has resulted in rich, alkaline soils that provide habitat for a diversity of plant life that is uncommon in the state. One set of plasma interactions that have not been fully explored are those which occur during high-velocity collisions between plasmas. Marauder, marauders, The Marauder, or The Marauders may refer to: Language links are at the top of the page across from the title. Description Evading railgun fire Depends on your skill/preference. Yeah, I never understood how you're supposed to get the plasma to stay plasma once you fire it. Please enter a valid email address (formatted as name@company.com). -, magnetic fields to shield the interior of a gun barrels, AN ANALYTIC MODEL FOR THE COMPRESSION OF PLASMA TOROIDS. https://en.m.wikipedia.org/wiki/MARAUDER Essentially its a still classified US military project aiming to develop a railgun capable of firing 0.5-2.0 mg toroids of plasma at up to 3% light speed.
