The U.S. Navy has spent $500 million developing a working railgun. Railroad Rail Lantern / Sign Stand Split With Axe. It has a good efficiency ( about 40%) and you can also control the output voltage(from 300V to 500V).its not very cheap but its so small and portable. 0000003465 00000 n i mean sure making a rail gun would be bitchin but you would also have to deall with some type of power source that can create 400volts verse just an air tank you strap to your back and refill off of a 120 volt air compressor?? 0000003604 00000 n Unfortunately, this means the video won't be ready untill some time after easter hols. An electromagnetic railgun is a device designed to launch a projectile at high speeds. This website is my engineering notebook. The pictures I have uploaded of my airsoft gun are old, as it fell off the shelf 2 weeks befor being marked (hitting a computer, edge of table and the arm of a chair) so had to be completely rebuilt, but most of the individual parts weren't to damaged, but it looks slightly different, and better now, and has a bi-pod attached to it, unfortunately all the photos are still on the school's computer, and i'm now on holiday, so they won't be up for a while. A railgun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. The EMRG utilizes an injector, a high voltage power supply, a capacitor bank, inductors and rails. 0000004619 00000 n I conducted a project to skim the surface of railgun physics and design. plans for DDG-51 procurement in those fiscal years, and how this relates, if at all, to a potential reduction in the force-level goal for large surface combatants (i.e., cruisers and destroyers) that might be included in a new Navy force-level goal that is to replace the Navy’s current 355-ship force-level goal; and cost, schedule, and technical risk in the Flight III DDG-51 … Put it all togeather, and you should have a working (or not) railgun. Details. 0000007546 00000 n An Electromagnetic Railgun (EMRG) was designed, built, and tested, capable of firing a projectile a 1 gram projectile at 650 m/s muzzle velocity. The second category is a kinetic weapon, involving railguns, coil guns and other electromagnetic- and plasma-propelled devices. 7, the armature is accelerated by the magnetic field. LIMITATION OF ABSTRACT UL NSN 7540-01-280-5500 Standard … This isn't really a problem except you will loose power befor you shoot. 0000010513 00000 n You can also use the flash circuit from disposable cameras, but to charge 8 capacitors of this size, I would need quite a few or risk burning the circuit, and disposable cameras aren't that cheap and shops now send them off somewhere after use, so I couldn't get any used ones. Navy Lasers, Railgun, and Gun-Launched Guided Projectile … However, it is made for airsoft (but it has to use 6mm steel ballbearings. Results: We put a barrier 24 ft away and it went over it, giving it a min speed of about 70 ft/s. 0000011163 00000 n 0000005339 00000 n The answer is... a paintball gun. 0000005838 00000 n This will be my next instructable, but will take a long time to make, as the total parts are around 70, plus the pneumatic and electric circuits (very simple). I first started by constructing a small railgun as a proof-of-concept. 0000002394 00000 n Bei den ersten Tests zeigten Sie schon ihre Qualitäten als Luftgewehr.             I used 10 400 volt 450uf aluminium electrolyte capacitors (step 2) The hardest thing would be to design a perfect ammunition & way to load automatically & eventually rapidly if I can get the gun to be efficient enough to take quicker shots !! i dont know if im wrong when it comes to thinking that the gun would be lighter if its just powered off of compressed air than having a bunch of batterys and capaactiors and metal rails, DIY Composite Layup and Vacuum Bagging - Making a Carbon Fiber RipSurf for Braille Skateboarding. Letztendlich ist die Railgun zu einer Plasmakanone mutiert. You simply need to connect  your cylinder to a valve, and then the valve to the barrel (this valve also acts as the trigger) and some way of refilling your cylinder (another valve connected to an aircompressor or foot pump), and a plastic barrel that is a tight fit with your projectile. QUANTAQUEST Quantum Secure Communication and Navigation for European Defence: In the future, quantum radars will make stealth aircrafts … To prevent both of these things happening, the projectile must already be moving befor it meets the rails at a sufficient speed to prevent it stopping. the distance between my rails was .252 . Unfortunately, i'm not sure if i'll ever be able to test my project as my physics department has a power supply that goes to 400 volts, but are worried about safety, ethics, legality... but i'll ever get my DC/AC inverter and do it that way, or use cameras. … 0000285677 00000 n The high voltage power supply charges the capacitor … 0000004854 00000 n 0000004444 00000 n Theoretically, yes. 0000287744 00000 n You also need enough voltage to make a good arc, so you probably need something at least in the 300v range. The Rail Gun – Basic Design and Principles of Operation Rail Gun Design The fundamental rail gun design derives from the concept of a linear electromagnetic motor. Currently, I am cutting aircraft grade aluminum I received as a donation, and planning how I'm going to insert the capacitors into the back,, and basically, it's really tough stuff. Barry's Coilgun Design Site Learn about coilgun design theory, design and implementation. 6 years ago You can add some sort of breach, but as this was a prototype for my main GCSE project (an airsoft gun) I only needed proof of concept, so didn't have enough time to bother with one. Railguns promise to make space travel and weapons systems much more efficient for the future. A railgun usually has magnetic coils mounted on either side of the rail system at right angles to the barrel, so as to generate Lorentz Force. 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. ! Yes, this helped me so much. 2 gas valves- 2 gives a faster rate of flow, but not necessary if using a spring. so,what i want to know is, does the ball bearing and the rail need to touch each other when it is fired ? It is powered by some electrical energy source (e.g., a capacitor bank) which provides a high urrent through a conductor on the projectile. the Navy’s plans for transitioning these weapons from development to procurement and fielding of production models aboard Navy ships; and whether Navy the Navy’s shipbuilding plans include ships with appropriate amounts of space, weight, electrical power, and cooling capacity to accommodate these weapons. 0000283519 00000 n              Steel tube (barrel)- diameter must be similar but slightly larger than you projectile. The easiest way of checking that us just by performing a curl command from the Railgun server to the origin web server. 0000002994 00000 n Like a "sleeve" that you bolt in place over the barrel with all the caps and wiring built in, all you will then need to do is find a way to activate the circuit automatically once the paintball gun has fired. hey if the projectile does not move try to hook up capacitors in parallel, so you get more microfarads. Successfully firing the graphite rails: railgun.avi . So I made a rail gun last year for science fair and when I made it I used .25 steel balls. The Navy plans for railguns to be able to intercept endo-atmospheric ballistic missiles, stealthy air threats, supersonic missiles, and swarming surface threats; a prototype system for supporting interception tasks is to be ready by 2018, and operational by 2025. • First railgun idea was given by French inventor Louis Octave in 1918 by designed an electric cannon. Checking that the route between the Railgun server and the web server is clear is essential before contacting support. This gives a total capacitance of 3600uf, but still at 400 volts. on Introduction. The theoretical advantage of this type of a futuristic weapon is that the velocity of the projectile is not limited by the burning rate of a chemical propellant used by traditional kinetic weapons (firearms). 0000288421 00000 n These rail guns will fire a … The US Navy is working on a few railgun projects that will eventually replace the largest guns on the fleet’s cruisers and destroyers. This is probably the cheapest and easyest option. This, when charged to 400 volts, produces 360 joules of energy, which is capable (excluding resistance, friction, all the other stuff) of 1011.26 m/s, but as this is actually a very inefficient design, the actual velocity will be a lot less. However, we think it hit the wall at a height of 15 inches, giving it a speed of 140 ft/s. This will be done in about 10 sections, so if one melts, then I don't have to replace the entire lot. The PowerLabs Linear ElectroMagnetic Accelerator ("Rail Gun", or "RailGun") research project officially began on February 21st 2001 when Sam Parler, research Director of Cornell Dubilier … 0000286932 00000 n It works the same way as the prototype (the railgun described earlier), but with a loading mechanism and a better compressed air system, making it a bolt action sniper. 0000286379 00000 n Hi....I already trying to build one. For instance, it is possible to run a current directly through the projectile to cause direct interaction between the weapon's magnetic propulsor coils and … Wobei man dazu erwähnen sollte, dass die Abschussvorrichtung mit 20 Kilo wirklich noch tragbar ist. Doch die Energiequelle für dieses Monster ist ein Kondensator-Verbund aus 56 einzelnen Kondensatoren, welche nochmals gute 90 Kilo auf die Waage bringen und damit ist die Waffe … Das Projektil kann dabei auch selbst als Schlitten dienen, dies ist aber wegen der sich widersprechenden Anforderungen (das Projektil mus… We have several low-power coilguns, maglev systems and other projects. If you use the paintball gun as the initial means of propulsion and then build a rail gun around it, would it work?              Gas reservoir- I used 4 small one, but a large single would be perfect, or use a spring. Hey maybe I will be able to combine my Railgun on to a Sentry Gun Platform !!! at hypersonic speeds lacks funding and has no coherent plan to deploy on warships the navy is instead naval electric weapons the electromagnetic railgun and free electron laser dec 06 2020 posted by jeffrey archer library text id c746bb43 online pdf ebook epub library coherent plan to deploy on warships the navy is instead pursuing naval electric weapons the electromagnetic railgun … Contribute to lz520520/railgun development by creating an account on GitHub. Uploaded: February 19th, 2014. This is called the Lorenz force. on Introduction, can i use less than ten capacitors i mean like 5 or 3 just asking, Reply Software: Other, STEP / IGES, SOLIDWORKS, Rendering, Categories: Energy and Power, Miscellaneous, Tags: device, energy, free, 75 Likes. 0000283856 00000 n SECURITY CLASSIFICATION OF THIS PAGE Unclassified 19. My video is only using 30volts, because at that point I did not have a DC/AC converter, but the result is still quite good, with some nice sparks coming from the end of the rails, and the person who does the "Oh my..." is not me, just a friend watching. Eine Railgun beschleunigt das Projektil durch die magnetische Wechselwirkung eines elektrischen Stromes, der über die Schienen auf das Projektil selbst oder auf einen hinter dem Projektil geladenen Treiber fließt, mit dem Magnetfeld des Schienenstromes selbst. 0000006567 00000 n When current is driven through the rails and armature, as shown in Fig. I am currently in the process of building a railgun similar to yours, but on a larger scale, and I needed help with a lot heading into this project, but this guide really helped me and it shown some important problems that I haven't put any thought into yet. To charge these to 400 volts, you can use two different methods. 0000284359 00000 n Connect the capacitors, the positive terminal to one rail, negative to the other. The rail gun was fired from a height of 25 inches with an angle of 1/10 inch / 6 inches so ~1 degree There are more powerful … PRICE CODE 17. (unfortunately, I don't have images yet, but I'll be sure to show you in the comments once I do! This is me building the first half of my second new and improved Rail Gun The metal projectile cannot simply be inserted into the rails, as you'll get electrocuted, and the projectile will get spot welded onto the the rails by the large electrical charge suddenly jumping across the projectile. However, this provides a poor connection area between your projectil and rail, and can cause more sparks and therefore faster errosion to your rails. However, the parts are not to expensive, but im not sure of how much it all came to as I built it at my school during DT lessons. on Introduction. Then, playing with about 10 different capacitor packs and light gates, I hope to be able to get the ball bearing (always hopeful) to 340m/s, the speed of sound! The accelerat … You don't have to used compressed air, but this was the quickest and easyest way for me as I only had to put the components togeather instead of build any parts. For my design, I used 8, 400V, 470uf capacitors connected in parrallel. 6 years ago. Also, after charging the capacitors, you must disconnect them from the charger as they will discharge back into the transformer. Railgun: US-Marine rüstet Zerstörer mit fürchterlicher Waffe aus. 0000286835 00000 n We show how to make a very simple railgun to illustrate how they work. 1 Railgun is also spelled as rail gun; EMRG is also abbreviated as EM railgun; hypervelocity is also spelled as hyper-velocity or hyper velocity. Reply I will be making an oval section of tubing, about a metre long, and wrapping the entire thing in 8swg enamelled copper wire (if i can find enough). 0000003160 00000 n 0000003297 00000 n However, the parts are not to expensive, but im not sure of how much it all came to as I built it at my school during DT lessons. You might have to cut down the barrel though, the standard barrel should be okay since they're mostly quite short and useless anyway.The loading problem has also then been solved as most paintball guns are semi-automatic and have hoppers attached, all you need is a the correct diameter projectiles.You might need some kind of separate battery-pack or else things will get real heavy. More to follow...... after exams!! For my A2, i'm hoping to change the coil gun/ rail gun idea and mix it with some ideas from the particle colliders. also, I post the pdf of the SP500 generator by creative studio and a lost pdf about railgun enjoy. 0000008517 00000 n 0000152419 00000 n Plan's powerful electromagnetic weapon also known as the railgun has been sighted at the Dalian port. This does use voltages upto 400V, and comnpressed air, so be carefull, and never put anyone at risk from whatever you manage to create. My system used 4 small gas reservoirs (you can use one, but these were all i had at the time, and my other large cylinder was attached to another project). Pneumatics pipes- reservoir to valve to barrel connections 0000285123 00000 n 0000286808 00000 n No, not nearly enough power.             Solid aluminium bar (for rails)- 20cm x 3cm x 3cm              (step 3) The way that these work is that a electrical current is conducted up one rail, across the projectile, and then back down the other rail (see picture). Aluminium was probably not a very good choice in material as it is quite soft (compared to steel), and can be damaged easily by any sparks made, with effects the connection between the rail and projectile for the next shot, but it was the easyist metal to work with. Das Projektil wurde durch Druckluft (8 bar) in die leidenden Kupferschienen … Now that the weapon works, there are no plans to make it an operational weapon system. Using this mechanism Cloudflare is able to achieve typical 99.6% compression (taking, for example, a 100k web page down to 400 bytes) and a speedup of over 700%. The railgun is a form of linear accelerator, using a electromagnetic force to propell an object. You kidding me? Unless you broke physics, your efficiency is going to be terrible (I've been calculating .5% in my design), so you need a lot of energy to start with. on Step 5. Then, the tubing will be surrounded in a shell of aero-gel, and providing the physics department like my project, filled with CO2 (not liquid as it turns from solid to gas almost instantly) to about -78 C. There will also be a small gap either side of the oval so you can see inside the tube, and so the light gate can measure the speed. Light Novel Pdf and Manga Download Link English Version hmm i think ultranova17 didn't have any plan to reupload these file (actually i save these in case i accidently delete it at my own PC but since there are some people who didn't have LN either Manga (Translated into English) then i'll share these Links mines) explosive devices, and autonomously plan offline and run-time missions plans. 2 As discussed later in the report, the Navy is exploring the potential for using shipboard lasers to counter small boats and unmanned aerial vehicles (UAVs), and EMRG can be used to attack land targets. It should work without them touching, as long as the current can jump the gaps, but probably not as well. My design fired 9mm steel ball bearings, which is fun, but can cause injury. if your using compressed air wouldnt it be simpler top just take the compress air hose hook it up to a barrel that just barely lets your projectile slide through put a notch in the spot were you want to load the projectile adn get a piece of tube that will slide over the spot where you load the projectile ad have some type of triger that when pulled causes the compressed air to be shhot into the barrel forcing the projectile out the end of the barrel and just demolising what ever you were aiming at???
