Get kits shipped in 24 hours. What's the intended of use of the few milligrams of plasma confined within the bullet? Now THERE is a coil gun. I WANT PLASMA WEAPONS!!!!! | Page 2 | SpaceBattles |. Come enjoy the rolling countryside 4 mile course, we are now celebrating our 20th annual event! At these magnetic field strengths (100T is currently achievable on the relevant timescale), you can exert enough force to crush most solid objects. Some references here about the American navy, but it is so far behind. Round is a solid KE penetrator. Or can it simply generate plasma on discharge? 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. I thought this was used primarily as an ASAT weapon? One way to do this would be by using superconducting coils and heat them to drop the superconductivity (sometimes known as a quench gun) but that'll turn the field energy into heat, and lots of it. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionised, gas-like particles, instead of a solid slug of material. A plasma-projectile shooting railgun is basically an armature that converts to plasma ('transitioning' armatures are also a thing and have been considered as a bridge between plasma armatures and solid/hybrid armature railguns, in fact) which is what Wikipedia describes (although the velocities are an order of magnitude less than what Shiva 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. Randy Curry and his friends were able to fire a self-contained ring of plasma in open air, that lasted for 10 milliseconds. What are the advantages of a coilgun v.s. 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 The United States is playing catch up in this area of weapons development at least it is in public. A plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature.However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material.Scientific plasma railguns are typically operated in vacuum and not at air pressure. However, the, Very nice first post Ben M. We invite you to take our. The author argues that to realize the hypervelocity potential of plasma armature railguns, restrike must be eliminated. New Progress on Plasma Weapons | Military.com Z-pinches also magnetically accelerate plasma up to similar velocities. If you continue to use this site, you consent to use all cookies. 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. Scan this QR code to download the app now. 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 bolts would also send out heat, potentially superheated metal shards, and an electromagnetic pulse that would scramble unshielded electronics. 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. They work a lot like a Smoke Ring does. Session ID: 2023-04-28:2c6aaeebb2aaad3ad105949e Player Element ID: vjs_video_3. Other than that, you're essentially constructing bullet-sized fluorescent tubes with some sort of attached supercapacitor that can provide ionization voltages for ~10s. Railguns, Coilguns, Helical Railguns, and Helical Coil - Reddit As fascinating of a topic as the research may be, the more important question is whether they went out of their way to make the project acronym marauder, or if it was just a fortunate coincidence that it ended up as that? [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. | Robotics for Kids Both are from Wikipedia. And it remains grounded in science. 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. 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). 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. | About Us All takedown requests will be promptly acknowledged and investigated. I'm asking from a viewpoint using known physics and materials, but pushing those limits to a realistic maximum even if such a design is not yet practical. Youve already signed up with this email address. 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. It is worth noting that at that speed the projectile exceeds orbital velocity at Low Earth Orbit. 'Marauder' was the US military's first plasma railgun - and it might We may have detected a typo. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. [citation needed], Arrays of plasma railguns could be used to create pulsed implosions of ~1 Megabar peak pressure, allowing more access to chart this opening area of plasma physics. The glowing light is emitted by plasma.). (10^10 gs, 1 s, etc). @apaul34208 It depends on how the bullet is constructed and how "super" your supercapacitor is. 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. The power requirement appears to be immense. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.

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. Can I use my Coinbase address to receive bitcoin? The Navy spent more than a . Is there such a thing as "right to be heard" by the authorities? Get started today! the #1 use for a weapon like this would most likely be ballistic missile defense, shooting down ICBMs or other strategic weapons. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionised, gas-like particles, instead of a solid slug of material. 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. ', referring to the nuclear power plant in Ignalina, mean? A round for standard infantry against nano-machined ceramics. Rank amateurs. More or less a tiny flash as the projectile is destroyed? Something similar was tried in original Star Wars SDI, huge power load, completely useless in atmosphere. Railgun | Military Wiki | Fandom rev2023.5.1.43405. What is Wario dropping at the end of Super Mario Land 2 and why? No one has heard a thing about the program since 1995. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? This is an instability in which the magnetic pressure front can out-run or "blow-by" the plasma armature due to the radial dependence of acceleration current density, drastically reducing device efficiency. Sogive us a quarter of your tail then? Railguns have long existed as experimental . I remain unconvinced that the principle has any potential as a weapon that can compete against solid or explosive projectiles. is able to confine plasma with minimal losses. A railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor. Non-superconducting projectiles will be subject to more heating!). How many gs could a coilgun or railgun shell withstand? one report published just over a decade after, Marauder was the US militarys first plasma railgun and it might have worked. | Mini Projects for Engineering Students MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. 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. Connect and share knowledge within a single location that is structured and easy to search. The Railgun - SP's Naval Forces This is obviously bad for your hopes and dreams. Build using online tutorials. What kind of protection system could be used against railguns? The Warwick Preserve was established when TNC received a 36-acre donation from Dr. Ruth Warwick and her daughter Louise Hunninen in 1964. If you still see this message after clicking the link, then your browser settings are likely set to not allow cookies. Designing plasma weapons that cannot pierce armour. Plasma railguns are capable of producing controlled jets of given densities and velocities ranging from at least peak densities 1e13 to 1e16 particles/m^3 with velocities from 5 to 200 km/s dependent on device design configuration and operating parameters. @StarfishPrime obviously 100m barrel does not give 10 times faster than 10m barrel. 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. It also cost a few million dollars every time the U.S. wanted to experiment with the technology, which is a much more likely reason the experiment ended up classified in mothballs. Project MARAUDER Developed by Phillips Laboratory. There is, however, no theoretical limit to barrel length or muzzle velocity, so if you want >10km/s you almost certainly want a coilgun. Its no secret the United States has been working on effective rail gun technology for years. In either design, a plasma armature is formed at the breech. It is noted that conventional plasma armature railguns are limited to velocities of 6-8 km/s by arc restrike. The USAF has already developed a plasma weapon that meets all but two of your requirements; but, it also bypasses their necessity. Plasma railguns appear in two principal topologies, linear and coaxial. I'm pretty sure the plasma was preheated and injected into the railgun. All proceeds help support the Westmoreland PTA and their great programming for the students and teachers of Westmoreland! What are your thoughts on the project MARAUDER plasma railgun? The importance of using plasma technology is that they produce muzzle velocities in 100s of km/shaving applications in magnetic confinement fusion (MCF), magneto-inertial fusion (MIF), High Energy Density Physics research (HEDP), laboratory astrophysics, and as a plasma propulsion engine for spacecraft. So a 100 meter barrel would have a speed of about 7900 meters per second. Renewed interest has arisen in plasma armatures as evidenced by two papers presented at the 2008 EML Symposium. Thanks for detailed post Connor. A device known as a plasma railgun can be used to produce plasmas which meet these experimental demands. You'd have to get it to impact and either lightly penetrate or adhere to the surface to sustain the arc for any appreciable length of time, yes. Would this system work better in space? How could dragons effectively use their wings as weapons in ground combat? Heat the projectile enough, and you have a diffuse and ever-expanding cloud of metal vapor, which is much less useful as an offensive weapon. At these magnetic field strengths (100T is currently achievable on the relevant timescale), you can exert enough force to crush most solid objects. To produce plasma-cutter-like effects on armored vehicles, which I assume is the goal, is slightly different, as the plasma in the above bullet won't last very long after the bullet impacts and the power source is (presumably) destroyed. Stay up-to-date and build projects on latest technologies, Blog | A weak plasma weapon prototype developed by MU. can hold plasma under higher pressures. Simple deform modifier is deforming my object. It's not them. Its rugged terrain includes the rushing waters of Partridge Brook and a mixed forest of hemlock, sugar maple, red oak, and basswood. Before that could happen, MARAUDER vanished into Classified Status. You'll also get much more rail damage per shot for a much faster railgun, making firing multiple rounds problematic. Presumably the induction magnets would be the entire length of the barrel, so it can accelerate for longer. This Sub focuses on discussing his videos and exploring concepts in science with an emphasis on futurism, space exploration, along with a healthy dose of science fiction. Plasma is to be found in all gas discharge lamps while in operation; it's not magical, it is an ordinary state of matter. Plasma railguns are capable of producing controlled jets of given densities and velocities ranging from at least peak densities 1e13 to 1e16 particles/m^3 with velocities from 5 to 200 km/s dependent on device design configuration and operating parameters. And yes, the magnetic properties of metals tend to go to pot once they melt. In December 1998, TNC accepted a donation of 68 acres from Ann Fisher; this addition increased the size of the preserve to 104 acres. Did you mean to type Here is a picture of the Chinese weapon, undergoing deployment shakedown trials. It only takes a minute to sign up. The Navy even developed the ability to fire multiple-shot salvos but neither service has effectively fielded a weapon. Marauder - Wikipedia Is it possible for a spheromak to maintain itself at high speeds under atmospheric conditions? A sabot round arrangement (or just crushing the plate into a pellet) will allow you to concentrate much of this energy in a penetrator. In what environment - vacuum, atmosphere, etc.? Otherwise, you will not be able to register for races or use other functionality of the website. In a plasma railgun, a short pulse of current is passed through a plasma located between two parallel electrodes, or "rails". It's a very slow particle beam in practice with ~8 millimeters of range in air if proton and ~10 if alpha particle. Please complete the following survey to help us better understand your race experience. Plasma railgun - Wikipedia JavaScript is disabled. Their design for plasma containment is called a Compact Toroid, and their design was similar to an arrangement called a Spheromak. Still not quite good enough for the satellite-based weapon that MARAUDER was meant to bebut pretty solid for ground-based combat. A railgun is a weapon that uses electromagnetic force to fire a projectile at high velocity, some at speeds of up to Mach 6. Is "I didn't think it was serious" usually a good defence against "duty to rescue"? A transferred plasma cutter works by inducing a plasma in a carrier gas, which creates a very conductive path between the electrode and the "target" material, which creates a tremendous amount of heat. TIL Project MARAUDER, a coaxial plasma railgun powered by the - Reddit (PDF) Plasma Armatures for Railguns - ResearchGate Railgun, plasma, beam, what's their difference? Glass, perhaps jacketed in something more durable like ceramic, could contain the plasma apparatus. Plasma requires constant electrical energy input to be maintained, so storing your plasma bullets is the biggest constraint, barring some sort of Infinite Power Supply. Honestly I find it hard to envision how a weaponized, long range railgun would make a 'torus' (that seems more a thing to do with coilgun style propulsion - some modesl literally do involve configurations to accelerate/propel ring shaped projectiles.) However, techniques including exploding foils, gas cell burst disk injection, neutral gas injection via fast gas valve, and plasma capillary injection have been employed. Why does Acts not mention the deaths of Peter and Paul? Railgun are less accurate, can fire from a longer range, do less damage against shield, have an average bigger dps. Although the technology used to develop the Marauder was theoretically laying the groundwork for more advanced energy production, namely some kind of fusion reactor, powering the weapon proved costly. If we magically start it off at 0K, we can see that it can absorb no more than 180kJ. Yet in a constant high acceleration starship setting.. plasma railguns are best used for defense, since a swarm of high thrust constant acceleration missiles could in theory overwhelm it's firing solution.
