Would this be at all practical as a weapon system? Plasma is to be found in all gas discharge lamps while in operation; it's not magical, it is an ordinary state of matter. Come enjoy the rolling countryside 4 mile course, we are now celebrating our 19th annual event! 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? Title VI Notice of Nondiscrimination If your projectile is 20mm across and your barrel is 100m long, the amount of energy is the swept volume will be a reasonable 0.5GJ, for a muzzle velocity of 70km/s. [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. View Directions and from everything I've dug up there's alot of conflicting data about it (some say. Mostly realistic weapons to assault a planet from orbit. After graduating from Boston University in 1904, Dr. Warwick and her first husband, Dr. Coles, operated a TB sanitarium in West Keene. What is the symbol (which looks similar to an equals sign) called? 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. Privacy Policy. Want to develop practical skills on Mechanical? 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. 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. I really do not understand the purpose of the 100m barrel, unless you are projecting a VERY big bullet. Depends on your skill/preference. The experiment published in 1993 required the use of Kirtland Air Force Bases Shiva Star capacitor bank. Better for close range brawling. Little is known about it after 1993 because it swiftly Classified Status. This may help a bit, but does impose some parasitic mass that will limit the muzzle velocity of the projectile (and makes calculation of the final velocity into some kind of horrid differential equation which I won't be solving for you). Get kits shipped in 24 hours. Your browser has JavaScript disabled. It's a big ship destroyer. Rare plants found here are the broad beech fern, a beautiful purple and white orchid called the showy orchis, spotted wintergreen, and long-spurred violet. Have bigger trouble hitting small target. Because even with those insane speeds, their 'Plasma Bolt' didn't live long enough to achieve a useful range ($3,000 km/s \times 1 \mu s = 3m$). a railgun? A 100m railgun might not, in fact, be 10 times faster than a 10m railgun, if it wanted to stay in one piece after firing. Your question/message has been sent to the race director. That's the best I could come up with, assuming he intended the plasma to cause damage. or 8,654 km/hr. You can enrol with friends and receive kits at your doorstep. He created a simple electric cannon, which caught the attention of the French military who were seeking a weapon that . can be shaped into a bullet. That speed makes it about 2,394 m/s. I think this technology could be useful potentially as a point defense system on space stations. Linear plasma railguns place extreme demands on their insulators, as they must be an electrically insulating, plasma-facing vacuum component which can withstand both thermal and acoustic shocks. cheaper and more accurate than traditional gunpowder-based methods. The Bulldog 4 is an annual fun run that also serves as a fundraiser for the Westmoreland PTA. And it remains grounded in science. 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. 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. Is "I didn't think it was serious" usually a good defence against "duty to rescue"? These weapons programs even look to be losing steam, especially when compared to the development of hypersonic missile technology. Ruth, George, and Louise enjoyed hiking around their Butterfield Hill property. @PcMan right, silly mistake. Little is known about it after 1993 because it swiftly Classified Status. While Vladimir Putin is busy touting Russias newest line of hypersonic weapons he is seemingly whipping the world into a frenzy about missiles flying past early warning systems. A traditional railgun uses electromagnetic forces to drive a solid metal projectile slug to superspeeds. Yet in scifi it is quite possible to have an uber plasma railgun that just kills missiles when they get too close. Basically, it looks like a donut. The plasma is confined between the bullet and the magnetic field pushing on it. "Containment" and "weapon" are typically contradictory. In a plasma railgun, a voltage is applied so that current can flow through the flat rail electrodes. So a 100 meter barrel would have a speed of about 7900 meters per second. Something similar was tried in original Star Wars SDI, huge power load, completely useless in atmosphere. Most don't need TeX formatting at all, if you know how to type. And everybody likes the alluring neon lights which enliven nights and hide the stars. In 1993, the Air Force Research Laboratory finally published an experiment in high-velocity plasma projectile weapons. In the case of our hypothetical 200T coilgun, that gives us a maximum energy density of 16GJ/m3. The design of individual gun components is detailed. Efficiency will drop, parasitic heat ratio will rise, and it will, @RossPresser focused engine plume will do thst without coilgun magic, enginr or alike fusion reactor. Stay up-to-date and build projects on latest technologies, Blog | This thesis discusses the design and characterization of a small coaxial plasma railgun intended to accelerate argon-helium plasma jets. Project MARAUDER Developed by Phillips Laboratory. 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. Please complete the following survey to help us better understand your race experience. Existing ground-based inertial confinement fusion pellets implode at ~300km/s, and are accelerated over a distance of a few mm (and this is far from the lab speed record). What's wrong with accelerating a metal slug beyond its melting point? Their design for plasma containment is called a Compact Toroid, and their design was similar to an arrangement called a Spheromak. In a plasma railgun, a short pulse of current is passed through a plasma located between two parallel electrodes, or "rails". The glowing light is emitted by plasma.). Connect and share knowledge within a single location that is structured and easy to search. The limit is 'cee' . Marauder, marauders, The Marauder, or The Marauders may refer to: Language links are at the top of the page across from the title. In coaxial plasma railguns, the electrodes are concentric. After observing an extensive clear-cutting operation on Butterfield Hill near their home, Ruth urged George to acquire the 36-acre parcel to preserve the beautifully wooded section of the hill. But whether you store plasma inside a bullet or create it from parts of the bullet, you're not going to induce plasma for very long with a projectile. A sabot round arrangement (or just crushing the plate into a pellet) will allow you to concentrate much of this energy in a penetrator. Beneath that you have fabric mesh surrounding the vehicle's inner hull that is tear resistant and some sort of self repair that will auto-fill any hole that is made. No one has heard a thing about the program since 1995. Accelerator electrode geometry and materials are also open areas of research. Experiments aimed to further the understanding of these interactions require the generation of plasmas with specified properties at very high velocities. T-shirts for the first 75 paid entrants, 15 years and up. Build using online tutorials. It will just ablate a thin layer of it. He describes two promising approaches which are based on demonstrated technology. Because of this, these devices have 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. How could dragons effectively use their wings as weapons in ground combat? 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). 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. Coaxial accelerators require insulators only at the breech, but the plasma armature in that case is subject to the "blow-by" instability. Would this system work better in space? But the OP specifically asked for "plasma contained in bullets". Or can it simply generate plasma on discharge? It's still an accelerating mass @RossPresser in general, because you can no longer rely on its intermolecular bonds to hold it together. 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. 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 best answers are voted up and rise to the top, Not the answer you're looking for? It is hoped that the work at the University of Texas described in these papers . 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. Did you mean to type Is it possible for a spheromak to maintain itself at high speeds under atmospheric conditions? Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? 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. for example, scramble or disable a random part of a, The containing should last for 10 secs, max, A small, extremely-highly-compressed canister of carrier gas, A bullet design that becomes a nozzle on impact (hollow-. Generating points along line with specifying the origin of point generation in QGIS. These are laser powered, and the shock waves due to the sudden acceleration heat the pellet substantially before it hits the center. Engineering Project Ideas | JavaScript is disabled. A high enough force in a short distance still produces a huge acceleration. You can now heat it up by more like 3MJ/kg instead of 900kJ/kg. A bigger projectile yields a higher payload, so a rifle-mounted tank buster could be devised. Randy Curry and his friends were able to fire a self-contained ring of plasma in open air, that lasted for 10 milliseconds. Why did US v. Assange skip the court of appeal? Reddit and its partners use cookies and similar technologies to provide you with a better experience. The experiment which was performed to confirm the properties of the plasma jets produced by the coaxial plasma railgun is explained. Unfortunately, George died in 1933 and Ruth returned to Boston in 1938 to set up a medical practice to support herself and her daughter. Charitable Solicitation Disclosures Ultimately, the limit is going to be keeping the bullet solid as you push on it. Plasma is not necessarily hard to confine; for example, those of us who are old enough or who have an interest in the history of computing remember the beautiful Nixie tubes which were used for the displays of computers and calculators made until the 1980s or so; Nixie tubes can be ruggedized, and some have flown in space aboard Soviet (and maybe also American) spacecraft. On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. If you continue to use this site, you consent to use all cookies. the #1 use for a weapon like this would most likely be ballistic missile defense, shooting down ICBMs or other strategic weapons. | Technical Resources 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. A traditional railgun uses electromagnetic forces to drive a solid metal projectile slug to superspeeds. What're the weight and dimensions of the slug? Re-arranging F=ma, you get a=F/m, no mention of distance. Glass, perhaps jacketed in something more durable like ceramic, could contain the plasma apparatus. A chemical gun benefits from a longer barrel because the expanding gases have longer to do their thing. MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. They are found as both ground emplacements and vehicle armaments. 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. Thank you!

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. 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. The plasma accelerator fires instantly, but the projectile is slow. Which was the first Sci-Fi story to predict obnoxious "robo calls"? It was named MARAUDER or magnetically accelerated ring to achieve ultrahigh directed energy and radiation.. That's not bad at all. 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. The Marauder uses the same principle in firing the weapon, but instead of the slug, Marauders projectile is superheated, donut-shaped ionized gas particles: plasma. Read how we use cookies and how you can control them by visiting our Privacy Policy. is able to confine plasma with minimal losses. At these magnetic field strengths (100T is currently achievable on the relevant timescale), you can exert enough force to crush most solid objects. 13-nautical-mile range of the US Navy's standard 5-inch naval gun," Parking space for three to four vehicles is available,just South of a small white-railed bridge. 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. Scientific plasma railguns are typically operated in vacuum and not at air pressure. The relevant principle is: use a plasma to push on your bullet. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. Why are players required to record the moves in World Championship Classical games? 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. If the shooting stars and the stuff hits the fan, Uncle Sam might pull the Marauder out of mothballs. All takedown requests will be promptly acknowledged and investigated. After graduating from Boston University in 1904, Dr. Warwick and her first husband, Dr. Coles, operated a TB sanitarium in West Keene. That's a nice round number, and doesn't rule out superconducting projectiles, as it should be below the critical field strength of futuristic high-temperature superconductors (see here for some analysis of YBCO, one of the best practical real-world superconductors). Its rugged terrain includes the rushing waters of Partridge Brook and a mixed forest of hemlock, sugar maple, red oak, and basswood. 24 Apr 2013 | Posted by Member 30298028.

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. Some references here about the American navy, but it is so far behind. MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. | Robotics for Kids The post Marauder was the US militarys first plasma railgun and it might have worked appeared first on We Are The Mighty. Which reverse polarity protection is better and why? What are your thoughts on Project MARAUDER? Also what kind of distance would these toroids be stable over? 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. 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 This is actually a design for a true plasma weapon that fires a bolt of magnetically contained plasma. 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. Terms of Use A plasma railgun is a linear accelerator uses two long parallel electrodes to accelerate a "sliding short" armature. | Terms & Conditions Featured photo: Shiva Star at theAir Force Research Laboratoryat Kirtland Air Force Base. | Designing plasma weapons that cannot pierce armour. Requesting that Material be Amended or Removed. Please wait while we submit your question/message. | Verify Certificate In December 1998, TNC accepted a donation of 68 acres from Ann Fisher; this addition increased the size of the preserve to 104 acres. The power requirement appears to be immense. don't forget we're getting 5 pounds of TNT yield out of a MILIGRAMS of material. They work a lot like a Smoke Ring does. If you believe that any material in VTechWorks should be removed, please see our policy and procedure for Check your spam folder if you do not receive it. Dr. Coles died in the 1917 flu epidemic. 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. What's the intended of use of the few milligrams of plasma confined within the bullet? 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. One set of plasma interactions that have not been fully explored are those which occur during high-velocity collisions between plasmas. The two requirements being 'shaped into a bullet' and 'survive for 10 seconds.' Similar principles apply for plasma railguns. Youve already signed up with this email address. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. A round for standard infantry against nano-machined ceramics. 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. The railgun has less ammo, but a little higher damage and (correct me if I'm wrong) it's better to shoot out subsystems. The results of this experiment confirm that the design succeeds in producing plasmas which meet targets for plasma properties.

The Warwick Preserve was established when TNC received a 36-acre donation from Dr. Ruth Warwick and her daughter Louise Hunninen in 1964. and our You might be able to hold it magnetically in the gun, but the instant it leaves the barrel you've now got rapidly cooling nothing. This answer (given technological development to improve power efficiency) meets all but two of your requirementsbut (potentially) bypasses their necessity. Its no secret the United States has been working on effective rail gun technology for years. the US Office of Naval Research says. I'm pretty sure the plasma was preheated and injected into the railgun.
