project marauder plasma railguns

projectiles up to 125 miles at 7.5 times the speed of sound, is Railgun has a charge time, but the projectile is very fast, so it's good for sniping. These weapons programs even look to be losing steam, especially when compared to the development of hypersonic missile technology. JavaScript is disabled. Project MARAUDER was a coaxial railgun that shot plasma donuts that exploded (I think) on impact and also caused an emp discharge. Did you mean to type The resulting projectile moved at $3,000 km/s$ and struck its target with a $\approx 5$ lb TNT explosion ($5 \times 10^{-7} kT = 2.092MJ$) ---and a potent, short-range electromagnetic pulse. 1,680 were here. Linear railguns consist of two flat plate electrodes separated by insulating spacers and accelerate sheet armatures. Would this be at all practical as a weapon system? While most of New Hampshire tends to have acidic soils, the calcium-rich bedrock in Westmoreland has resulted in rich, alkaline soils that provide habitat for a diversity of plant life that is uncommon in the state. The problem is that everything is classified so we have no way to know if it is to hide a viable weapon or to keep the enemy guessing and thus spending money to find a way to counter it or create their own. the railgun can launch projectiles much farther than the Ultimately, the limit is going to be keeping the bullet solid as you push on it. 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. However, it is rumored to be a coil gun, not a rail gun. Ruth, George, and Louise enjoyed hiking around their Butterfield Hill property. Resources for Engineering Students | Thank you! Unfortunately, George died in 1933 and Ruth returned to Boston in 1938 to set up a medical practice to support herself and her daughter. Description. Additionally, a complex triple joint seal may exist at the breech of the bore, which can often pose an extreme engineering challenge. Please enter a valid email address (formatted as name@company.com). Why is it shorter than a normal address? Identify blue/translucent jelly-like animal on beach. 2023 The Nature Conservancy The Air Force has been at this game for decades, though, and its previous work is more advanced than anything coming out of the Navy Department, Russia, China or even Kim Jong Uns wildest dreams. 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). | Verify Certificate In the case of our hypothetical 200T coilgun, that gives us a maximum energy density of 16GJ/m3. 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. The author argues that to realize the hypervelocity potential of plasma armature railguns, restrike must be eliminated. MARAUDER was a United States Air Force experiment to develop long-range plasma weapons. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. Before that could happen, MARAUDER vanished into Classified Status. or 8,654 km/hr. Renewed interest has arisen in plasma armatures as evidenced by two papers presented at the 2008 EML Symposium. There's no free lunch to be had here! 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. http://www.navweaps.com/Weapons/WNUS_Rail_Gun.php. The best answers are voted up and rise to the top, Not the answer you're looking for? Her three grandchildren continue to visit the preserve. 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.

The U.S. Navy and Air Force have both developed railgun prototypes. The preserve is located on Butterfield Hill in a quiet part of southwestern New Hampshire, not far from the Connecticut River. 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). It's still an accelerating mass @RossPresser in general, because you can no longer rely on its intermolecular bonds to hold it together. The system shown on our data is a relatively low velocity device within the building capability of most hobbyists. On impact, the electrode is pushed back into the power supply and the carrier gas is released through the nozzle created on impact. The official Subreddit for the Isaac Arthur YouTube channel. You can find instructions at https://www.whatismybrowser.com/guides/how-to-enable-cookies/auto. 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. The Bulldog 4 is an annual fun run that also serves as a fundraiser for the Westmoreland PTA. In either design, a plasma armature is formed at the breech. 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. You cannot get anything better unless you use magical materials, or magical ultra-efficient coilguns (and this example is already quite magical). Both are from Wikipedia. All proceeds help support the Westmoreland PTA and their great programming for the students and teachers of Westmoreland! Please wait while we submit your question/message. Railgun technology, which uses electromagnetic force to send Randy Curry and his friends were able to fire a self-contained ring of plasma in open air, that lasted for 10 milliseconds. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It revolved around firing electromagnetically contained plasma out of a railgun encased in a toroidal (donut shaped) container. 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. Can I use my Coinbase address to receive bitcoin? The limit is 'cee' . 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. You'll also get much more rail damage per shot for a much faster railgun, making firing multiple rounds problematic. If you continue to use this site, you consent to use all cookies. It seems like a really cool concept. If we have a 200g projectile with the specific heat capacity of steel (500J/KgK) and the melting point of steel (say, 1800K) we can see that the projectile's temperature will raise by 1K for every 100J of wasted energy. Can you still use Commanders Strike if the only attack available to forego is an attack against an ally? Plasma railguns are electromagnetic accelerators used to produce controlled high velocity plasma jets. What is a realistic maximum velocity of a coilgun round from a 100 m barrel? View Directions Some features of this site may not work without it. Get started today! Come enjoy the rolling countryside 4 mile course, we are now celebrating our 19th annual event!

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. Its rugged terrain includes the rushing waters of Partridge Brook and a mixed forest of hemlock, sugar maple, red oak, and basswood. Mobile Terms & Conditions But the muzzle velocity is sqrt(2 * barrelLength * acceleration). The power requirement appears to be immense. How are engines numbered on Starship and Super Heavy? Terms of Use 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. cheaper and more accurate than traditional gunpowder-based methods. ', referring to the nuclear power plant in Ignalina, mean? Little is known about it after 1993 because it swiftly Classified Status. Picture of a historical neon discharge tube by Pslawinski. When Ruth died in 1973, Louise scattered her ashes on the preserve. Some handwaving of high-capacity, high-voltage, extremely compact and inexpensive supercapacitors will be needed. 13-nautical-mile range of the US Navy's standard 5-inch naval gun," What's the intended of use of the few milligrams of plasma confined within the bullet? | Playto It was named MARAUDER or magnetically accelerated ring to achieve ultrahigh directed energy and radiation.. Why are players required to record the moves in World Championship Classical games? MARAUDER took these Compact Toroids and fired them from a railgun. This answer (given technological development to improve power efficiency) meets all but two of your requirementsbut (potentially) bypasses their necessity. 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. Otherwise, you will not be able to register for races or use other functionality of the website. A bigger projectile won't help you; you need one with a higher melting point, a larger heat capacity, and a more efficient coilgun to get the speeds you want. What's wrong with accelerating a metal slug beyond its melting point? Dr. Coles died in the 1917 flu epidemic. Has the Melford Hall manuscript poem "Whoso terms love a fire" been attributed to any poetDonne, Roe, or other? 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. Would this system work better in space? 24 Apr 2013 | Posted by Member 30298028. 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. A tokamak is essentially an infinitely long rail/coil gun that produces a magnetic containment vessel for a super-heated plasma. This website uses cookies to enhance your experience and analyze performance and traffic on our website. The plasma is accelerated until it leaves the muzzle of the railgun.
