How could you make a cat's tail prehensile enough to use weapons? 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. Of course, you could do much better than a puny 400km/s with a laser-pushed ablator because you can maintain the acceleration till you hit the target. Session ID: 2023-04-28:2c6aaeebb2aaad3ad105949e Player Element ID: vjs_video_3. Some believe that we may not be far from getting containment times measured in Milliseconds ($ms$). 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 sabot round arrangement (or just crushing the plate into a pellet) will allow you to concentrate much of this energy in a penetrator. Ruth married George Warwick in 1923 and they moved to Westmoreland. Some features of this site may not work without it. That's a bit better, but remember: this is a maximum, regardless of anything else like barrel length, or field strength, or projectile weight. It revolved around firing electromagnetically contained plasma out of a railgun encased in a toroidal (donut shaped) container. Connect and share knowledge within a single location that is structured and easy to search. | FAQs [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. 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. No hunting on the southern portion of the preserve (Warwick parcel). [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. Coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Would this system work better in space? It's a big ship destroyer. 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. Its the same lab used to produce energy enough for the SDI initiative (also known as Star Wars missile defense). 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. Would My Planets Blue Sun Kill Earth-Life? It is hoped that the work at the University of Texas described in these papers . To review your email preferences, please visit nature.org/emailpreferences. The results of this experiment confirm that the design succeeds in producing plasmas which meet targets for plasma properties. What's wrong with accelerating a metal slug beyond its melting point?

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? Mostly realistic weapons to assault a planet from orbit. 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. The U.S. Air Force Research Laboratory must have made some significant progress in a short time, because computer simulations started in 1991, an experiment was conducted in 1993, and the whole thing was classified not long after. Take CERN, for instance. 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. can hold plasma under higher pressures. is capable of surviving speeds and acceleration up to 2 km/s. [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. A coaxial railgun has one rail as a cylindrical shell encircling the other rail. Forty-foot high rocky outcrops provide views of the river. and our T-shirts for the first 75 paid entrants, 15 years and up. I think this technology could be useful potentially as a point defense system on space stations. In a plasma railgun, the armature and ejected projectile consist of hot, ionized, gas-like particles heated by a very high temperature. The experiment which was performed to confirm the properties of the plasma jets produced by the coaxial plasma railgun is explained. They are found as both ground emplacements and vehicle armaments. cheaper and more accurate than traditional gunpowder-based methods. 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 approach of creating the plasma on contact. PS: I'd wager my whole tail that MARAUDER is an offshoot of the RACE torus experiments in late 80s. 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. What are the advantages of a coilgun v.s. Which reverse polarity protection is better and why? MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. If you still see this message after clicking the link, then your browser settings are likely set to not allow cookies. However, it is rumored to be a coil gun, not a rail gun. the US Office of Naval Research says. Coaxial accelerators require insulators only at the breech, but the plasma armature in that case is subject to the "blow-by" instability. 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. Both are from Wikipedia. It was named "MARAUDER" - or "magnetically accelerated ring to achieve ultrahigh directed energy and radiation.". That's the best I could come up with, assuming he intended the plasma to cause damage. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. | Mini Projects for Engineering Students Railgun | Project Wingman Wiki | Fandom 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.

This website uses cookies to enhance your experience and analyze performance and traffic on our website. @StarfishPrime obviously 100m barrel does not give 10 times faster than 10m barrel. How many gs could a coilgun or railgun shell withstand? On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. Existing knowledge of coaxial railgun plasma instabilities and material interactions at vacuum and plasma interfaces are applied to the design. To manage or opt-out of receiving cookies, please visit our. One set of plasma interactions that have not been fully explored are those which occur during high-velocity collisions between plasmas. The railgun has less ammo, but a little higher damage and (correct me if I'm wrong) it's better to shoot out subsystems. Something similar was tried in original Star Wars SDI, huge power load, completely useless in atmosphere. 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. Plasma is a gaseous state of matter which is electrically conductive and interacts with electric and magnetic fields. 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.

Hand Held Coil Gun cannon - Enough to rip a giant robot limbs into pieces, Reimagined Weaponry: The Illidari Warglaives. I really do not understand the purpose of the 100m barrel, unless you are projecting a VERY big bullet. Accelerator electrode geometry and materials are also open areas of research. What were the most popular text editors for MS-DOS in the 1980s? Did you mean to type Their design for plasma containment is called a Compact Toroid, and their design was similar to an arrangement called a Spheromak. 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. In coaxial plasma railguns, the electrodes are concentric. Plasma railguns appear in two principal topologies, linear and coaxial. For a better experience, please enable JavaScript in your browser before proceeding. Learn More. I remain unconvinced that the principle has any potential as a weapon that can compete against solid or explosive projectiles. 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.
