I charged mine to around 120PSI, but the amount of pressure you need depends on the weight of your projectile. on Introduction. 0000009934 00000 n 0000285123 00000 n Bei den ersten Tests zeigten Sie schon ihre Qualitäten als Luftgewehr. 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. For my A2, i'm hoping to change the coil gun/ rail gun idea and mix it with some ideas from the particle colliders. 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 … 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. 0000284703 00000 n 0000286379 00000 n [Capacitors must be charged using DC current, not AC, aluminium electrolite capacitors can only be charged in one direction, else they can heatup, melt, or explode]. This timeframe suggests the weapons are planned to be installed on the Navy's next-generation surface combatants, … 2 gas valves- 2 gives a faster rate of flow, but not necessary if using a spring. 0000004082 00000 n For the Compressed air system;                                                         (step 4) Das Projektil kann dabei auch selbst als Schlitten dienen, dies ist aber wegen der sich widersprechenden Anforderungen (das Projektil mus… Don't point it at anyone, and discharged the capacitors befor handling after each shot as they don't always full discharge. An electromagnetic railgun is a device designed to launch a projectile at high speeds. We show how to make a very simple railgun to illustrate how they work. The EMRG utilizes an injector, a high voltage power supply, a capacitor bank, inductors and rails. 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. I actually now have 10 400 volt 480uf capacitors (I forgot about the last two). 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. Wobei man dazu erwähnen sollte, dass die Abschussvorrichtung mit 20 Kilo wirklich noch tragbar ist. Contribute to lz520520/railgun development by creating an account on GitHub. The U.S. Navy has spent $500 million developing a working railgun. 0000283519 00000 n Reply ! So I made a rail gun last year for science fair and when I made it I used .25 steel balls. However, it is made for airsoft (but it has to use 6mm steel ballbearings. 0000286808 00000 n This is me building the first half of my second new and improved Rail Gun on Introduction. Barry's Coilgun Design Site Learn about coilgun design theory, design and implementation. 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. 0000004619 00000 n In my design, i use two parallel aluminium strip and the gap between 2 rails is 2.1 cm and the diameter of the ball bearing is 2 cm. 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). This will be done in about 10 sections, so if one melts, then I don't have to replace the entire lot. 5 years ago. I would not really recommend going anywhere near the mains and sticking stuff in, so the best option is to build, or even better, buy a DC/AC converter (there are lots of small car converters you can buy that run on 12v batteries), and then connect a transformer to the output, and add a semi-conductor diode to change it back to DC power. Chemical propellants are limited to under 5000 m/s … 0000284359 00000 n The injector fires 2300 psig Nitrogen gas into the system to provide an initial velocity.

Reply how about a marx generator? Uploaded: February 19th, 2014. I then delved deeper into the physics of operation by measuring and modeling the magnetic field associated with the operation of the device. When current is driven through the rails and armature, as shown in Fig. on Introduction. 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. This is probably the cheapest and easyest option. Hi....I already trying to build one. here is a very helpful boost converter https://www.instructables.com/id/DC-DC-HV-Boost-Con... 8 years ago But when i'm firing it, the ball bearing was not sped like your's. 0000005099 00000 n 0000012394 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. It should work without them touching, as long as the current can jump the gaps, but probably not as well. Reply on Introduction. 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 !! 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. More to follow...... after exams!! For electrical (the rail gun) Railgun Armatures James R. Gaier Lewis Research Center Cleveland, Ohio Clarence E. Gooden Eglin Air Force Base Fort Walton Beach, Florida Doreen Yashan Cleveland State University Cleveland, Ohio Steve Naud Naval Coastal Systems Laboratory Panama City, Florida Prepared for the 5th Symposium on Electromagnetic Launch Technology sponsored by the Institute of … You can do the more dangerous way (don't unless you actually do know exactly what your doing) of putting the correct step-up transformer into a plug socket and then adding a semi-conductor diode You kidding me? mines) explosive devices, and autonomously plan offline and run-time missions plans. This website is my engineering notebook. We have several low-power coilguns, maglev systems and other projects. There are more powerful … The rail gun was fired from a height of 25 inches with an angle of 1/10 inch / 6 inches so ~1 degree SECURITY CLASSIFICATION OF ABSTRACT Unclassified 20. Railroad Rail Lantern / Sign Stand Split With Axe. Das Projektil kann dabei auch selbst als Schlitten dienen, dies ist aber wegen der sich widersprechenden Anforderungen (das Projektil muss wegen der Aerodynamik schlank sein, der Schlitten dagegen … I clamped these togeather, with a sheet of perspex between the two. 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?? • In world war 2, the German Commander Luftusaffe issued a specification for a railgun based anti-aircraft gun. Navy Lasers, Railgun, and Gun-Launched Guided Projectile … 0000288448 00000 n 400 Volt RAIL GUN: For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. 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. 0000002372 00000 n A railgun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high velocity projectiles. 0000285555 00000 n The launch package, consisting of the armature and payload, is initially pressed between the rails at the breech end. These rail guns will fire a … Theoretically, yes. hey if the projectile does not move try to hook up capacitors in parallel, so you get more microfarads. 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! 7, the armature is accelerated by the magnetic field. Could a 20volt 1 Farad capacitor be used for this build? Railgun: US-Marine rüstet Zerstörer mit fürchterlicher Waffe aus. 0000003465 00000 n 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. 0000004854 00000 n Now that the weapon works, there are no plans to make it an operational weapon system. Details.             Solid aluminium bar (for rails)- 20cm x 3cm x 3cm              (step 3) Preferably, yes, they need to touch, other it might not get a constant current flowing through, and there will be more arching, which will erode your rails faster and result in even less contact. 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 … The second category is a kinetic weapon, involving railguns, coil guns and other electromagnetic- and plasma-propelled devices. 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. so,what i want to know is, does the ball bearing and the rail need to touch each other when it is fired ? Unfortunately, this means the video won't be ready untill some time after easter hols. • First railgun idea was given by French inventor Louis Octave in 1918 by designed an electric cannon. View all. Its mounted to a Type 072III-class landing ship Haiyang Shan and was earlier seen in a shipyard in Wuhan. a cool idea would be a farnsworth fusor but there really expensive if you want actual results. I got plan's from a guy that built a "Sentry Gun" Which I am in the middle of building also !!! The usual way is to use two parrellel metal strips, with a gap just large enough for your projectile. 0000288421 00000 n 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. not in series. Hopefully, the physics department will be more supportive of this project and help me with the power supplies. 0000287744 00000 n SECURITY CLASSIFICATION OF REPORT Unclassified 18. 0000286738 00000 n 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. This isn't really a problem except you will loose power befor you shoot. Most of this project can be changed, so you don't have to use these exact parts, but these are what I used for mine. 0000002817 00000 n I first started by constructing a small railgun as a proof-of-concept. Then, I drilled down the center of the two blocks and perspex, with a drill bit slightly larger than my projectile, forming a abrrel with two metal sides with a plastic insulation between the two. However, this provides a poor connection area between your projectil and rail, and can cause more sparks and therefore faster errosion to your rails. Plan's powerful electromagnetic weapon also known as the railgun has been sighted at the Dalian port. 9 years ago 0000003160 00000 n on Step 5. you could use diodes for the problem of energy going back into the transformer issue you mentioned. The high voltage power supply charges the capacitor … Unless you can find some small, light, long-lasting, high-voltage batteries. yay. No, not nearly enough power. 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 … 0000011729 00000 n             Acrylic 20cm x 3cm x 0.2cm. SECURITY CLASSIFICATION OF THIS PAGE Unclassified 19. 0000009375 00000 n Pneumatics pipes- reservoir to valve to barrel connections 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. 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. Hey maybe I will be able to combine my Railgun on to a Sentry Gun Platform !!! Put it all togeather, and you should have a working (or not) railgun. 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. 3 years ago.

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. There are more powerful versions, but this doesn't take long to build and is quite effective. 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 projectile normally does not contain explosives, instead relying on the projectile's high speed, mass, and kinetic energy to inflict damage. 0000003604 00000 n Railgun Technology: A railgun consists of parallel conducting rails connected by a sliding contact called an armature. Please ask if you have any questions. 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. railgun, solid-state switches, pulsed power supply, electromagnetic launch, thyristors, spark-gap switches, naval railgun 16. 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). Railguns promise to make space travel and weapons systems much more efficient for the future. But, that'll take another year, and won't truly be started until after the summer. The US Navy is working on a few railgun projects that will eventually replace the largest guns on the fleet’s cruisers and destroyers. For this instructable I will explain how to make a simple rail gun, firing metal ballbearings. Also, after charging the capacitors, you must disconnect them from the charger as they will discharge back into the transformer. 6 years ago However, we think it hit the wall at a height of 15 inches, giving it a speed of 140 ft/s. (unfortunately, I don't have images yet, but I'll be sure to show you in the comments once I do! The accelerat … 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. 0000004444 00000 n the distance between my rails was .252 . Pneumatics?You could make a regular spring magazine so every shot it will reload automatically(unlike in regular ARs, which require the gas to push the bolt back). LIMITATION OF ABSTRACT UL NSN 7540-01-280-5500 Standard … The answer is... a paintball gun. There are several potential variations of the railgun that successfully meet these criteria. 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%. My design used a solid aluminium bars about 20cm x 3cm x 1.5cm. The railgun is a form of linear accelerator, using a electromagnetic force to propell an object. Letztendlich ist die Railgun zu einer Plasmakanone mutiert. 0000003297 00000 n 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 and free electron laser nov 29 2020 posted by j k naval electric weapons the electromagnetic railgun and free electron laser dec 11 2020 posted … 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. 0000283856 00000 n 9 years ago 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). 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. 0000003940 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). Results: We put a barrier 24 ft away and it went over it, giving it a min speed of about 70 ft/s. 6 years ago 0000011163 00000 n 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??? However, you will only be getting 1/2 to 1/3 the power, which may not be enough to drive your projectile. If not, it'll look awesome anyway. The end of your barrel should feed directly into the rails. 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). 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. You also need enough voltage to make a good arc, so you probably need something at least in the 300v range. These will be connected to 40 amp continuous dc power supplies, with a ball bearing inside the tubes. 0000002994 00000 n 0000285972 00000 n try making a 400V boost converter . on Introduction, can i use less than ten capacitors i mean like 5 or 3 just asking, Reply Der große Vorteil solcher Railguns, die genauso wie Laserkanonen zu den Waffen der … 0000152419 00000 n It is not very neat, but I didn't have much time as it was only meant to be an alternative way of building an airsoft gun using a new system (part of my GCSE project). 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 … I did this 3 times, and the put the three sections togeather to form one long barrel/rail. 0000007546 00000 n H��V]o�8}G�?�Gg�v�/i4�j��t[V#mg�4RH�$�����״[BCV3Ǿ>>>���ɴj��Y7���d�4f�h7�0�(���}�,��vrkҬ0MV�>���.����)�P��~$�"��Pq �F-�#H��@@J��p�������`�0�:Y �c��A�f?���K����)�����/`=��5^��ٺS`��uSa�,uch}fm-.��ڧ4i�љ k��3�R��k�Á/|@��(H �B��\�P����(N����M�19╫. %PDF-1.5 %���� 757 0 obj << /Linearized 1.0 /L 1154720 /H [ 288448 817 ] /O 760 /E 289265 /N 23 /T 1139535 /P 0 >> endobj xref 757 53 0000000015 00000 n 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.             I used 10 400 volt 450uf aluminium electrolyte capacitors (step 2) Railgun uses a new caching mechanism based on comparing page versions to determine what needs to be transmitted across the Internet to the Railgun Sender. Project Introduction: This page is no longer being updated.
