The approach of creating the plasma on contact. It is one of several United States Government efforts to develop plasma-based projectiles. The best answers are voted up and rise to the top, Not the answer you're looking for? this region. Gentle acceleration up to 100km/s over 100m doesn't have to liquidize your bullet. "Using a massive electrical pulse rather than a chemical propellant, Marauder, marauders, The Marauder, or The Marauders may refer to: Language links are at the top of the page across from the title. Thick Dual layered angled armor outter hull is the first basic level defense. 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. can hold plasma under higher pressures. I'm not sure if this would be able to disable a tank with a single shot, but it is scalable assuming you have this kind of super-capacitive tech. A bigger projectile yields a higher payload, so a rifle-mounted tank buster could be devised. Here is a picture of the Chinese weapon, undergoing deployment shakedown trials. I'm pretty sure the plasma was preheated and injected into the railgun. The plasma is accelerated until it leaves the muzzle of the railgun. It's not them. |. Is it possible for a spheromak to maintain itself at high speeds under atmospheric conditions? Mr. Parsons was a perfectionist in his plans he and his crew have done our lawn maintenance for the past 3 years and it looks awesome. A railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor. They are found as both ground emplacements and vehicle armaments. Railgun has a charge time, but the projectile is very fast, so it's good for sniping. ;). What does 'They're at four. | Privacy Policy Would this be at all practical as a weapon system? I think this technology could be useful potentially as a point defense system on space stations. Why does Acts not mention the deaths of Peter and Paul? This set up is not feasible with current technology, as most railgun power sources can only operate barely long enough to fire the projectile. It's still an accelerating mass @RossPresser in general, because you can no longer rely on its intermolecular bonds to hold it together. He describes two promising approaches which are based on demonstrated technology. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. 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. Physics:Plasma railgun - HandWiki What should I follow, if two altimeters show different altitudes? It revolved around firing electromagnetically contained plasma out of a railgun encased in a toroidal (donut shaped) container. Their design for plasma containment is called a Compact Toroid, and their design was similar to an arrangement called a Spheromak. [1], Magneto-inertial fusion seeks to implode a magnetized D-T fusion target using a spherically symmetric, collapsing, conducting liner. I still see them. | Contact Us, Copyright 2015-2018 Skyfi Education Labs Pvt. On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. Does it have to specifically contain plasma? With a 10 meter barrel, we get about 2500 meters per second. Ultimately, the limit is going to be keeping the bullet solid as you push on it. [duplicate], fire a self-contained ring of plasma in open air, Picture of a historical neon discharge tube, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. After graduating from Boston University in 1904, Dr. Warwick and her first husband, Dr. Coles, operated a TB sanitarium in West Keene. We use cookies to offer you a better browsing experience. | Mini Projects for Engineering Students There are possibly other things you might be able to do, like packing your projectile in some kind of coolant that is melted and evaporated to cool the projectile as it is accelerated. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. (Picture of a Nixie tube by Hellbus. in 2017, but as a possible energy storage mechanism, not much different from a plasma-armature, Real-Life Plasma Rounds With Surprising Penetration in a Pill Sized Package! Yes, Shiva Star, that was the '80es project I was thinking about. and our Similar principles apply for plasma railguns. Depends on your skill/preference. Sogive us a quarter of your tail then? Similar principles apply for plasma railguns. can be shaped into a bullet. It's travelling at 1-3 percent the speed of light. That's a bit better, but remember: this is a maximum, regardless of anything else like barrel length, or field strength, or projectile weight. Is "I didn't think it was serious" usually a good defence against "duty to rescue"? The power requirement appears to be immense. | Final Year Projects for Engineering Students If you continue to use this site, you consent to use all cookies. 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. 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. Mechanical Kit will be shipped to you and you can learn and build using tutorials. Yeah, I never understood how you're supposed to get the plasma to stay plasma once you fire it. For a better experience, please enable JavaScript in your browser before proceeding. @RossPresser but really what will happen is that if your gun pumps enough eneergy into the round to melt it, it'll almost certainly pump enough energy into it to at least partially boil it, and it'll go bang. As plasma railguns are an open area of research, the method of armature formation varies. Jet velocity and density are characterized by analyzing diagnostic data collected from a Rogowski coil, interferometer, and photodiode. 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. Please wait while we submit your question/message. A plasma railgun is a linear accelerator uses two long parallel electrodes to accelerate a "sliding short" armature. Privacy Policy. An asynchronous coilgun relies on the projectile having a certain bunch of properties (you need to induce a current in it, to provide a magnet field for the main gun coils to push against), and a coilgun with superconducting projectiles needs the projectiles to remain superconducting, and so they have to stay below their critical temperature, etc. In this sci-fi world, plasma weapons are somewhat abundant in special forces, as their ammunition can be stored in smaller spaces, and in large quantities, but I ran into a problem regarding confinement: can be created quickly. JavaScript is disabled. Like this page and invite your friends on Facebook. Dr. Coles died in the 1917 flu epidemic. We can now have a maximum muzzle energy of more like 1.2GJ, which for a 200g round gives us a muzzle velocity of nearly 110km/s. It's a big ship destroyer. Description Evading railgun fire Spreading that same force over a larger distance I do not think adds anything to the equation acceleration wise. Which means that I am in the potentially unique situation of being able to tell you that yes, they went out of their way to name it Marauder because it took us far too long to find a word that worked, we spent two hours fiddling with syllables to get stuff that fit (Direct Energy Railgun gives der). Railguns give you much more oomph for the same length barrel, but unfortunately shooting them causes damage to the rails as a result of the super-hot plasma arc that forms behind the projectile. Open in Maps, Explore our work in Forty-foot high rocky outcrops provide views of the river. If it breaks out by accident, even if it destroys everything would you still call it a 'weapon' ? We're still messing with the specifics of the donut (how tall is it, how wide is it, how big is the hole, how much plasma do we shove in, how hot should the plasma be, etc), but the basic consensus is that Toroids are the ideal shape for a self-sustaining plasma bolt. This is obviously bad for your hopes and dreams. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. That's the best I could come up with, assuming he intended the plasma to cause damage. The two requirements being 'shaped into a bullet' and 'survive for 10 seconds.' Please enter a valid email address (formatted as name@company.com). Can I use my Coinbase address to receive bitcoin? 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. Session ID: 2023-04-28:2c6aaeebb2aaad3ad105949e Player Element ID: vjs_video_3. You can now heat it up by more like 3MJ/kg instead of 900kJ/kg. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. [1] 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. A sabot round arrangement (or just crushing the plate into a pellet) will allow you to concentrate much of this energy in a penetrator. [citation needed] Plasma rail guns are being evaluated for applications in magnetic confinement fusion for disruption mitigation and tokamak refueling. 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. What are your thoughts on the project MARAUDER plasma railgun? A plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature.
