Flying Pig Antiques | Westmoreland NH - Facebook The near-term solution is some form of circuit arrangement which eliminates current . Peak line-integrated electron number densities of approximately 8 10. What is a realistic maximum velocity of a coilgun round from a 100 m In a plasma railgun, the armature and ejected projectile consist of hot, ionized, gas-like particles heated by a very high temperature. What is the symbol (which looks similar to an equals sign) called? I think this technology could be useful potentially as a point defense system on space stations. Engineering Project Ideas |
Parking space for three to four vehicles is available,just South of a small white-railed bridge. Based on current proposed weapons, we can estimate the rough acceleration we can achieve with a rail gun and scale that up. A bigger projectile yields a higher payload, so a rifle-mounted tank buster could be devised. 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. Donations are tax-deductible as allowed by law. Still not quite good enough for the satellite-based weapon that MARAUDER was meant to bebut pretty solid for ground-based combat. Maybe the same function might be achieved some other way. |. That last issue was the real sticking point. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. (Note that there will be other limits to projectile temperature superconducting projectiles musn't be heated above their critical temperature, for example, and that'll be a lot lower than their melting point: ~300K for a scifi "room temperature" superconductor, for example. When Ruth died in 1973, Louise scattered her ashes on the preserve. Other alkaline-loving plants found here include maidenhair spleenwort, spring beauty, and Dutchmans breeches. [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. A minor scale definition: am I missing something? Please enable JavaScript if possible. So a 100 meter barrel would have a speed of about 7900 meters per second. This page is not available in other languages. Marauder, marauders, The Marauder, or The Marauders may refer to: Language links are at the top of the page across from the title. This was the project's biggest issue. | The strength of the magnetic field is limited by a bunch of inconvenient things. 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. Coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor. What's wrong with accelerating a metal slug beyond its melting point? You must log in or register to reply here. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. I thought this was used primarily as an ASAT weapon? In a plasma railgun, a short pulse of current is passed through a plasma located between two parallel electrodes, or "rails".

Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. That said, this would require a much bigger power source, that would sustain for a longer acceleration. Open in Maps, Explore our work in Louise attended college, married and moved away. 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. [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. For more information, please see our Modern Science generally acknowledges that a donut-shape is the best shape for containing Plasma. @StarfishPrime obviously 100m barrel does not give 10 times faster than 10m barrel.

TIL Project MARAUDER, a coaxial plasma railgun powered by the - Reddit Learn more about Stack Overflow the company, and our products. Check your spam folder if you do not receive it. While currently, there are bans on orbital anti-ICBM weaponry, a MARAUDER-armed satellite could probably be an extremely effective Anti-ICBM weapon. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 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. 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. | ;).

It is hoped that the work at the University of Texas described in these papers . Get kits shipped in 24 hours. ', referring to the nuclear power plant in Ignalina, mean? 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. What are your thoughts on Project MARAUDER? : IsaacArthur - Reddit Yes, Shiva Star, that was the '80es project I was thinking about. How could I contain plasma for use in weapons? However, the, Very nice first post Ben M. We invite you to take our. 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. To manage or opt-out of receiving cookies, please visit our. Forty-foot high rocky outcrops provide views of the river. and from everything I've dug up there's alot of conflicting data about it (some say. They do still have scaling issues: you have to turn off a coil the instant the projectile is in the middle, and it is hard to simply vanish the field of a very powerful magnet! 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-. @RossPresser You want a compact, high velocity projectile to deliver a kinetic energy strike on a small spot. 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. Obviously, your story, your hands to wave, but this stuff is important to remember if you want a hard-ish scifi setting. 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. Otherwise, you will not be able to register for races or use other functionality of the website. From here take a right onto Route 63 and travel 0.9 mile to arrive at Warwick Preserve access point. Randy Curry and his friends were able to fire a self-contained ring of plasma in open air, that lasted for 10 milliseconds. This thesis discusses the design and characterization of a small coaxial plasma railgun intended to accelerate argon-helium plasma jets. On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. Railgun | Military Wiki | Fandom It may not display this or other websites correctly. JavaScript is disabled. T-shirts for the first 75 paid entrants, 15 years and up. 24 Apr 2013 | Posted by Member 30298028. And yes, the magnetic properties of metals tend to go to pot once they melt. And a plasma bolt with a lifespan of a millisecond, moving at 10,000km/s has a range of 10km. If technology was developed to fix this it might affect the acceleration speed. 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). AGM Landscaping. Landscaping Company - Porch The experiment which was performed to confirm the properties of the plasma jets produced by the coaxial plasma railgun is explained. Physics:Plasma railgun - HandWiki 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. University of Alabama in Huntsville LOUIS The Navy even developed the ability to fire multiple-shot salvos but neither service has effectively fielded a weapon. From Route 9 take Route 12 north for 6.4 miles, bringing you to east Westmoreland. the US Office of Naval Research says. Terms of Use @apaul34208 It depends on how the bullet is constructed and how "super" your supercapacitor is. That's a bit better, but remember: this is a maximum, regardless of anything else like barrel length, or field strength, or projectile weight. 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.
