Railguns, Coilguns, Helical Railguns, and Helical Coil - Reddit [citation needed]. The Railgun - SP's Aviation This current generates a magnetic field which propels the plasma forward. This current generates a magnetic field which propels the plasma forward. You cannot get anything better unless you use magical materials, or magical ultra-efficient coilguns (and this example is already quite magical). At least with the second approach, you can store your bullets normally. You are using an out of date browser. This page is not available in other languages. 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? What are your thoughts on the project MARAUDER plasma railgun? View Directions | Verify Certificate [1], Magneto-inertial fusion seeks to implode a magnetized D-T fusion target using a spherically symmetric, collapsing, conducting liner. Reportedly, Ruth asked a local handyman to clear out a spring on the side of Butterfield Hill to provide water for the animals in the woods this is still visible at the end of the first steep section of the preserves hiking trail. To get the 1.2GJ we want for our 100km/s super-coilgun, we'd need the projectile to sweep out ~0.074m3, which for a 20mm projectile works out as a barrel that's 236m long. MARAUDER, a U.S. government nuclear fusion research project Merauder, an American metalcore band Masked Marauder, a fictional Marvel Comics character Merrill's Marauders, United States commando unit in World War II This disambiguation page lists articles associated with the title Marauder. Since the driver current through the armature is also moving through and normal to a self-generated magnetic field, the armature particles experience a Lorentz force, accelerating them down the length of the gun. | Playto (Picture of a Nixie tube by Hellbus. A YouTuber by the name of NSA_Listbot has created a railgun that shoots plasma rounds and they were strong enough to fully penetrate a cantaloupe. Some features of this site may not work without it. Above the rocky outcrops, the trails are easier and follow gently curving contours through a mixed forest, which includes some beautiful stands of red oak. Plasma railguns are categorized in two principle topologies, linear and coaxial where linear railguns consist of two flat plate electrodes separated by insulating spacers and accelerate sheet armatures and coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor. Plasma gets more electrically conductive as it heats up, and your bullet stays in the barrel so little time, the plasma won't conduct much heat to the bullet. The USAF has already developed a plasma weapon that meets all but two of your requirements; but, it also bypasses their necessity. Accelerator electrode geometry and materials are also open areas of research. Skyfi Labs helps students learn practical skills by building real-world projects. Online Courses for Kids Would this be at all practical as a weapon system? However, the, Very nice first post Ben M. We invite you to take our. Agm is extremely professional we needed to expand our property to accommodate an RV and relieve a drainage problem next to our garage! That's the best I could come up with, assuming he intended the plasma to cause damage. Depends on your skill/preference. To review your email preferences, please visit nature.org/emailpreferences. What does 'They're at four. The strength of the magnetic field is limited by a bunch of inconvenient things. The problem is that everything is classified so we have no way to know if it is to hide a viable weapon or to keep the enemy guessing and thus spending money to find a way to counter it or create their own. eject plasma at extremely high speeds (some plasma railguns are designed to fire projectiles, but testing has shown that solid armatures are more effective due to lower electrical resistances found in metals [4]). The official Subreddit for the Isaac Arthur YouTube channel. Reddit and its partners use cookies and similar technologies to provide you with a better experience. What is a realistic maximum velocity of a coilgun round from a 100 m [citation needed], High velocity jets of controllable density and temperature allow astrophysical phenomena such as solar wind, galactic jets, solar events and astrophysical plasma to be partially simulated in the laboratory and measured directly, in addition to astronomic and satellite observations. At these magnetic field strengths (100T is currently achievable on the relevant timescale), you can exert enough force to crush most solid objects. How could I contain plasma for use in weapons? T-shirts for the first 75 paid entrants, 15 years and up. Why don't we use the 7805 for car phone chargers? | Robotics for Kids The U.S. Navy and Air Force have both developed railgun prototypes. Her three grandchildren continue to visit the preserve. | Terms & Conditions Why are players required to record the moves in World Championship Classical games? In a plasma railgun, a voltage is applied so that current can flow through the flat rail electrodes. can be shaped into a bullet. After graduating from Boston University in 1904, Dr. Warwick and her first husband, Dr. Coles, operated a TB sanitarium in West Keene. It is generally believed that MARAUDER was eventually scrapped. For a better experience, please enable JavaScript in your browser before proceeding. I really do not understand the purpose of the 100m barrel, unless you are projecting a VERY big bullet. Controlled jets from plasma rail guns can have peak densities in the 1013 to 1016 particles/m3 range, and velocities from 5 to 200 km/s, depending on device design configuration and operating parameters, and the upper limits may be higher. In private, the U.S. military might be way ahead of Russia in the area of ultra-fast projectiles, but well never know because most of its early developments have been classified. A railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor. What kind of protection system could be used against railguns? New Progress on Plasma Weapons | Military.com The plasma is accelerated until it leaves the muzzle of the railgun. Please enter a valid email address (formatted as name@company.com). And it remains grounded in science. 2023 The Nature Conservancy Better for close range brawling. | Refund Policy Say, if the primary problem of MARAUDER is that a plasma Torus will quickly become ineffective in the atmosphere, wouldn't that make a perfect weapon to put on a Satellite? The concept of the railgun, a technology that could utilize a large circuit to launch a projectile far further than one launched via the use of a chemical reaction, was developed by Andre Louis Octave Fauchon-Villeplee. In order to use RunSignup, your browser must accept cookies. Sogive us a quarter of your tail then? A sabot round arrangement (or just crushing the plate into a pellet) will allow you to concentrate much of this energy in a penetrator. The other example is the MARAUDER (Magnetically Accelerated Ring to Achieve Ultra-high Directed-Energy and Radiation) used the Shiva Star project (a high energy capacitor bank which provided the means to test weapons and other devices requiring brief and extremely large amounts of energy) to accelerate a toroid of plasma at a significant . Railgun | Project Wingman Wiki | Fandom A visit to the preserve in late spring or early summer will reveal some of these plants as well as neo-tropical migrant birds, including warbler and thrush species, and scarlet tanagers. Coaxial accelerators use various techniques to mitigate this instability. The Air Force has been at this game for decades, though, and its previous work is more advanced than anything coming out of the Navy Department, Russia, China or even Kim Jong Uns wildest dreams. What's interesting about a Compact Toroid, however, is that they are capable of maintaining structural stability for a fraction of a second after release from the external magnetic fields that created it. You can find instructions at https://www.whatismybrowser.com/guides/how-to-enable-cookies/auto. The United States is playing catch up in this area of weapons development at least it is in public. 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 MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. Why did US v. Assange skip the court of appeal? In a plasma railgun, a short pulse of current is passed through a plasma located between two parallel electrodes, or "rails". You could work out the require currents for a given size of superconductor, limited by the material's critical current, but lets instead go for 200 Tesla. He describes two promising approaches which are based on demonstrated technology. | Privacy Policy A railgun is a weapon that uses electromagnetic force to fire a projectile at high velocity, some at speeds of up to Mach 6. This paper discusses the design and testing of a small, relatively low power coaxial plasma railgun. The Navy even developed the ability to fire multiple-shot salvos but neither service has effectively fielded a weapon. Railguns are just high velocity rounds so standard plus extra defenses will work. In coaxial plasma railguns, the electrodes are concentric. (10^10 gs, 1 s, etc). How to force Unity Editor/TestRunner to run at full speed when in background? Coaxial accelerators require insulators only at the breech, but the plasma armature in that case is subject to the "blow-by" instability. Is "I didn't think it was serious" usually a good defence against "duty to rescue"? This means that railguns have scaling problems you can't shoot them too much before the rails need replacing, and the rail damage goes up with muzzle velocity so you may find a railgun that works just fine at 3km/s (at least for a little while) will be wrecked at 10km/s and explode violently at 30km/s. TL: DR, .a 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. The Navy spent more than a . The best answers are voted up and rise to the top, Not the answer you're looking for? TIL Project MARAUDER, a coaxial plasma railgun powered by the - Reddit A device known as a plasma railgun can be used to produce plasmas which meet these experimental demands. Railguns, sometimes called mass drivers, are kinetic energy weapons used extensively in the After Calamity Era. Please wait while we submit your question/message. Learn more about Stack Overflow the company, and our products. For a rough idea, you can use Luke Campbell's approximation for coilgun performance, which basically imagines the gun as a tube of energy in the form of the magnetic field, which is swept out by a projectile that turns it into kinetic energy. | FAQs That last issue was the real sticking point. It only takes a minute to sign up. A plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature. Z-pinches also magnetically accelerate plasma up to similar velocities. Specific elements of the design are examined and the inherent physical and material difficulties of a coaxial design are explored. @ Xavon_Wrentaile I have been thinking about this, and I do not think it needs to be. 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. All proceeds help support the Westmoreland PTA and their great programming for the students and teachers of Westmoreland! Would My Planets Blue Sun Kill Earth-Life? Marauder - Wikipedia JavaScript is disabled. A plasma railgun is a linear accelerator uses two long parallel electrodes to accelerate a "sliding short" armature.
