project marauder plasma railguns

Where the electromagnetic railgun fires a projectile at supersonic speeds of up to Mach 6, the Marauder would fire its one-meter diameter plasma rounds at 10,000 kilometers per second, or 3% of the speed of light. Project MARAUDER Developed by Phillips Laboratory. At these magnetic field strengths (100T is currently achievable on the relevant timescale), you can exert enough force to crush most solid objects. In 1993, the Air Force Research Laboratory finally published an experiment in high-velocity plasma projectile weapons. The best answers are voted up and rise to the top, Not the answer you're looking for? From Route 9 take Route 12 north for 6.4 miles, bringing you to east Westmoreland. That speed makes it about 2,394 m/s. The plasma is confined between the bullet and the magnetic field pushing on it. (PDF) Plasma Armatures for Railguns - ResearchGate However, techniques including exploding foils, gas cell burst disk injection, neutral gas injection via fast gas valve, and plasma capillary injection have been employed. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. Plasma railguns are electromagnetic accelerators used to produce controlled high velocity plasma jets. The Railgun - SP's Aviation Project MARAUDER was a coaxial railgun that shot plasma donuts that exploded (I think) on impact and also caused an emp discharge. 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.

Description Evading railgun fire According to one report published just over a decade after the whole thing went dark, the Marauder program was capable of firing ball lighting bolts that would explode on impact with the force of five pounds of TNT. When Ruth died in 1973, Louise scattered her ashes on the preserve. Railguns don't scale very well, due to the problem of the armature plasma cooking the rails. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? After armature formation, the plasmoid is then accelerated down the length of the railgun by a current pulse driven through one electrode, through the armature, and out the other electrode, creating a large magnetic field behind the armature. 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. They work a lot like a Smoke Ring does. What is a realistic maximum velocity of a coilgun round from a 100 m barrel? the railgun can launch projectiles much farther than the Its the same lab used to produce energy enough for the SDI initiative (also known as Star Wars missile defense). Learn More. Non-superconducting projectiles will be subject to more heating!). You may experience issues registering or using other parts of the website. In December 1998, TNC accepted a donation of 68 acres from Ann Fisher; this addition increased the size of the preserve to 104 acres. Charitable Solicitation Disclosures You can assume that any figures this gives are over-optimistic, but it isn't a bad upper-bound for coilgun performance. A tokamak is essentially an infinitely long rail/coil gun that produces a magnetic containment vessel for a super-heated plasma. I think this technology could be useful potentially as a point defense system on space stations. 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. However, the, Very nice first post Ben M. We invite you to take our. BATH, Maine The U.S. Navy has pulled the plug, for now, on a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity. Please enter a valid email address (formatted as name@company.com). How could I contain plasma for use in weapons? This is obviously bad for your hopes and dreams. We'll give your coilgun an efficiency of 99.9%, and half the wastage goes to heating up the projectile again. Requesting that Material be Amended or Removed. Resources for Engineering Students | 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. The Warwick Preserve was established when TNC received a 36-acre donation from Dr. Ruth Warwick and her daughter Louise Hunninen in 1964. What are your thoughts on the project MARAUDER plasma railgun? Plasma railguns appear in two principal topologies, linear and coaxial. The approach of creating the plasma on contact. or 8,654 km/hr. In what environment - vacuum, atmosphere, etc.? Plasma, Coils, or both? :: Terra Invicta Gameplay Discussion On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. A minor scale definition: am I missing something? [1] "Containment" and "weapon" are typically contradictory.

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). your coils are now bigger, and higher power, and need more current to reach the same strength. The two requirements being 'shaped into a bullet' and 'survive for 10 seconds.' 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. The electrode strikes a plasma arc to the target, creating a conductive path and emptying the capacitor into the target. Especially against space debris. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? | Robotics Online Classes for Kids by Playto Labs JavaScript is disabled for your browser. It was Motivated by RACE, though I don't know if that's enough to be an off shoot. one report published just over a decade after, Marauder was the US militarys first plasma railgun and it might have worked. The plasma is accelerated until it leaves the muzzle of the railgun. 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 round for standard infantry against nano-machined ceramics. @StarfishPrime obviously 100m barrel does not give 10 times faster than 10m barrel. 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. Read how we use cookies and how you can control them by visiting our Privacy Policy. [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. Other than that, you're essentially constructing bullet-sized fluorescent tubes with some sort of attached supercapacitor that can provide ionization voltages for ~10s. 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. Similar principles apply for plasma railguns. Simple deform modifier is deforming my object. can be shaped into a bullet. However, it is rumored to be a coil gun, not a rail gun. 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. This was the project's biggest issue. What does 'They're at four. 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. Basically, it looks like a donut. Flying Pig Antiques | Westmoreland NH - Facebook 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. The first thing we care about is efficiency our coilgun will inevitably cause the projectile to heat up as a result of induced currents, and if we heat it up to melting point the projectile will disintegrate making it much less useful as a weapon or worse: it'll explode, taking a chunk of your ship with it. They are of value because they produce muzzle velocities of up to several hundreds of kilometers per second. He created a simple electric cannon, which caught the attention of the French military who were seeking a weapon that . What's wrong with accelerating a metal slug beyond its melting point? If the shooting stars and the stuff hits the fan, Uncle Sam might pull the Marauder out of mothballs. The Navy spent more than a . As plasma railguns are an open area of research, the method of armature formation varies. Lets say that our coilgun is 99% efficient, and of the 1% of the energy that it wastes, half of it goes into the projectile. How are engines numbered on Starship and Super Heavy? 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? Reddit and its partners use cookies and similar technologies to provide you with a better experience. 13-nautical-mile range of the US Navy's standard 5-inch naval gun," 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. Plasma is a gaseous state of matter which is electrically conductive and interacts with electric and magnetic fields. Peak line-integrated electron number densities of approximately 8 10. Ltd. All Rights Reserved. Working backwards, this gives us a maximum kinetic energy of ~35MJ and so a maximum muzzle velocity of 18km/s, regardless of anything else about our gun. What are your thoughts on Project MARAUDER? Your message was posted to Facebook. Designing plasma weapons that cannot pierce armour. However, in recent years, new research has shown promise in extending the lifespan of these Toroids. The official Subreddit for the Isaac Arthur YouTube channel. Railgun | Project Wingman Wiki | Fandom This thesis discusses the design and characterization of a small coaxial plasma railgun intended to accelerate argon-helium plasma jets. 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). This creates your localized heat for as long as the arc can be maintained, greatly weakening or destroying the material at the point of impact. 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. @PcMan right, silly mistake. Design and Characterization of a Coaxial Plasma Railgun for Jet A high enough force in a short distance still produces a huge acceleration. ', referring to the nuclear power plant in Ignalina, mean? You must log in or register to reply here. The post Marauder was the US militarys first plasma railgun and it might have worked appeared first on We Are The Mighty. If you continue to use this site, you consent to use all cookies. It is generally believed that MARAUDER was eventually scrapped. 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. More or less a tiny flash as the projectile is destroyed? @apaul34208 It depends on how the bullet is constructed and how "super" your supercapacitor is. That's not bad at all. Experiments aimed to further the understanding of these interactions require the generation of plasmas with specified properties at very high velocities. Little is known about it after 1993 because it swiftly Classified Status. It's a very slow particle beam in practice with ~8 millimeters of range in air if proton and ~10 if alpha particle.

Plasma just doesn't last very long outside of carefully controlled scenarios. MARAUDER ( Magnetically Accelerated Ring to Achieve Ultra-high Directed Energy and Radiation) is, or was, a United States Air Force Research Laboratory project concerning the development of a coaxial plasma railgun. It's still an accelerating mass @RossPresser in general, because you can no longer rely on its intermolecular bonds to hold it together. | 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. The glowing light is emitted by plasma.). In a plasma railgun, a short pulse of current is passed through a plasma located between two parallel electrodes, or "rails". If you still see this message after clicking the link, then your browser settings are likely set to not allow cookies. Description. 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. Where does the version of Hamapil that is different from the Gemara come from? Developed by Phillips Laboratory. Get started today! However, your browser doesn't appear to allow cookies by default. Weighted sum of two random variables ranked by first order stochastic dominance. This set up is not feasible with current technology, as most railgun power sources can only operate barely long enough to fire the projectile. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? 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.

What should I follow, if two altimeters show different altitudes? Why is it shorter than a normal address? 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. Allow that bolt of plasma to break out, and you have a really potent weapon. What're the weight and dimensions of the slug? 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. ETDs: Virginia Tech Electronic Theses and Dissertations, Requesting that Material be Amended or Removed. But the muzzle velocity is sqrt(2 * barrelLength * acceleration). PS: I'd wager my whole tail that MARAUDER is an offshoot of the RACE torus experiments in late 80s. How could I contain plasma for use in weapons? [duplicate] 1,680 were here. The U.S. Navy and Air Force have both developed railgun prototypes. Plasma railguns are being evaluated for applications in magnetic confinement fusion for disruption mitigation and tokamak refueling. That's a bit better, but remember: this is a maximum, regardless of anything else like barrel length, or field strength, or projectile weight. Want to develop practical skills on Mechanical? Skyfi Labs helps students learn practical skills by building real-world projects. Online Courses for Kids Does it have to specifically contain plasma? Your browser has JavaScript disabled. Scan this QR code to download the app now. Mechanical Kit will be shipped to you and you can learn and build using tutorials. In coaxial plasma railguns, the electrodes are concentric. Existing knowledge of coaxial railgun plasma instabilities and material interactions at vacuum and plasma interfaces are applied to the design. 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. Plasma Railguns. Any Good Use? - Science & Spaceflight - Kerbal All proceeds help support the Westmoreland PTA and their great programming for the students and teachers of Westmoreland! A plasma railgun is a linear accelerator uses two long parallel electrodes to accelerate a "sliding short" armature. | Contact Us, Copyright 2015-2018 Skyfi Education Labs Pvt. Basically, the Marauder was everything an army could possibly hope for in the area of field artillery: an ultra-fast, super-destructive gun whose ammunition was only limited to how much power the army could produce for it. 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.
