Making a RAILGUN and then TESTING it!
Hey. Guys in case you didn't know the US Navy has been developing, an electromagnetic, railgun for, the past decade, and it's, absolutely incredible. It's. A highly futuristic, weapon that seems straight out of science fiction, using, only electricity, it can accelerate a projectile, to, speeds of Mach 6, that's, over 7,400. Km/h. Plus. It, has a range of over, a hundred and sixty kilometers, if you guys want more information, on that railgun check out the link in the description below anyway. World, of warships approached, us and offered, to sponsor a project, based on their game, naturally. We suggested, building a small-scale, version of, the, Navy's railgun world. Of warships is the perfect balance between action, and strategic, gameplay plus. If you use my link in the description below and are one of the first 300, viewers to use it you'll get an awesome bonus which will give you a huge head start in the game but, more, on that later in the meantime let's. Start building a real gun. Alright, so before we build a real gun let's talk about how a railgun actually, works you. See a railgun converts, electrical, power into, kinetic energy by creating a magnetic field that can accelerate a projectile. Here's. The diagram showing, how that works now the factor that determines how powerful, a railgun is is how much current you can push through those rails for. More detailed explanation, on how rail, guns work I'd recommend checking out electrical, booms video right, here so, the question is how do we build a power supply that, can provide enough current to make a powerful railgun. Most. Of the time we use lithium, polymer batteries, for our projects, and that's because they have some of the highest energy, densities available. In battery, form the, problem is they can't actually put out that much current for, that you need a capacitor, which can discharge huge, amounts of current in a really short amount of time in, fact we've. Already had a lot of fun with these capacitors, with Thor's hammer how to place a capacitor, inside. Of Thor's hammer. And if it's pretty good. That's. Loud, as, you. Can see it packs quite a punch. Now. One. Capacitor, isn't enough we're. Going to use 16. That's. Big, balls. That's. Hella heavy. This. Noah. Guy, is. After a half. See. You distract you, yes. That. Spacely. All, right, you one up me over the flamethrower. No. I. Had. To start you have to turn the pressure on low, there. Was probably downstairs. Now crack it. Okay. First this is charting Starkid. Just. Now. See my fuse blows. Rich. Shoes. She's, doing their bug, so. We are going to test. How long it's gonna take for this charger to charge up our battery, bank. Capacitor. Bank. Safety. Glasses. Cuz. We're not to discharge this thing after. So. They should be able to charge the power bank we're gonna see how long's gonna take everywhere. Double check that the step-down works as well to make sure we can actually measure the voltage on the bank without blowing up every single money meter we have. Including. This one. Okay. Do you want a welding mask, you. Sure. Okay. You ready. Great. Oh yeah, we shorted it. Now. That's a tenth of the voltage so, that's actually forty. Volts right now fifty volts. Sixty. Volts 7d. Right. Why are you wearing that drone fair shirt again, cuz. It's black it matches the Hackman it's not black that is great it's. A lot better than blue. 330. Volts. Big. Hair pulls me back I. Stopped. Being the host and just be the camera guy I. Stopped being the host and just become this camera guy so. Much fun. Okay. It. Does need to be charging a little. Boy. Ah. Geez. I missed. We, need a wood stick. That's. Fine oh. Sweet. It's probably, it's. Still a to 12 volts. Mmm. We're, getting our timers. Atomized. Aluminum, great, for the brain about. Two minutes charge. Big. Spark. Success. Thanks. Jerry. Now, I'm not a machinist, by any means and this is my first time using a CNC lathe so, let's just hit go and see what happens. All. Right so you might be wondering why we have a paintball, gun attached to the railgun and that's because you do actually need to initially accelerate, the projectile, because if you just put this in between the rails and turn the capacitor mekka on it would literally weld itself shut it needs to have a little speed at the beginning as it's entering the rails so we've taken this uh 0.5.
Caliber Paintball gun and we've. Turned the pressure down a little bit as you can see it's not very powerful. It. Is fast enough to make sure this projectile, doesn't well itself in place. Three. Four, hey. Nice. Da. For. Now. You sunk my battleship. You'll, pay. Safe. G5. Miss. What. I'd. Like to thank our sponsor at world of warships as, you can imagine this is a rather expensive build and we had to outsource quite, a few components which cost quite a bit of money so. I'd like to talk a little bit about the game, world. Of warships is a huge multiplayer, game with over seven million players you can command a massive, naval fleet featuring some of history's most iconic, war vessels including the, USS Indianapolis, Plus, unlock, new ships as you prepare to dominate the oceans in world of warships the. Game, is highly detailed including, changing, weather effects which make each battle unique and the, tactics you use with, constant updates every week this game is ever-evolving, and quite honestly really, amazing, apparently. It takes the developers around six months to introduce a new vessel into the game they, take tons of resources like the blueprints, and photographs actually, design, the model from scratch if, you guys want to check out the game and support our channel in doing so use my links in the description below plus, if you're one of the first 300 years to sign up you'll get an awesome bonus of two hundred fifty two balloons 1, million credits the HMS campbellton, and so. Much more, now, let's test out our very own railgun. Ooh this. 4748. All. Right what, are we going up to. 150. And then we put that switch. That's gardeners. O-152. Unbelievable. Come on dance get some actors. Behind, your ballistic, shields that don't exist. Well. That was cool it's, not loaded right yeah hit me cool. Point. Whoever. That was incinerated. But. It look cool and it broke the plate so. The, navy's, railgun actually, has a. A. Disposable. Casing, around the shell so, it's actually got on artillery shell and then, a casing, which would get all this damage to it that actually flies off of it and it propels the, projectile. Forwards. No. Fine, fine. Yeah all right yeah, before it blows up. Mmm. Toasty. It. Doesn't work. Fire. Power. This. Needs to be researched Davis, language. Next, victim. You, know I'd like, to use technically, I are serious right. That. Can't be good, 30, actually huh. Like. It works, pretty well last shot. That. There's a second shot, higher booster, shot, yes yeah. So it. Is better with. Higher. Voltage it's right. It's. Doing the railgun thing, it's. Actually the air out of it, yeah. Try for depressing, the pimp yeah. That's look, yeah. Well. It landed directly in the middle of the plate, Bon, Appetit. Sir. Do you wanna. Watch. This gonna it's gonna do this happy thing it, can. Oh wow. You're. Not gonna expect it turns. On. Sex day 180. What, are we going up to Your Honor it pretty. Mean what do we don't, know you know when to stop. What. You're. 40 kiss this time sensitive, date. Okay. Ready. Stopping. At two 261. Shit. Come on cameras ready that really looks. To. Be. Where. Is it oh there it is. Have. An awesome shot nice. Shot James. There. You go thank you. King. Henry the eighth's first, boy. All. Right so I just realized we haven't really explained, what. Everything does on the railgun so let's go through the system first we have the main power switch down here on and, off and then we have a three position power switch up here, plus, we have a little voltmeter which tells us the charge of the capacitor bank so, when, the switch is in the middle position is neutral, it's not doing anything and it's ready to be fired to, charge it simply push the switch forwards and as, you can see the, voltmeter starts, adding. Up. Alright, so just for example. We're. Going to stop it right there at about, a hundred and thirty volts now. The, reverse position, actually engages. The series of resistors, on top and this is to discharge, the capacitor bank in case you don't want to fire it because, it's actually very dangerous, considering. It can go up to 400 volts and we'll, put out thousands. And thousands of amps we just certainly enough to kill you so. If, you've decided not to fire the gun simply, pull the switch back and as you can see the voltage drops off almost immediately as all, the current is drained, through these resistors, so.
With. That being said let's. Charge it up to the full 400, volts and see what happens. To. 2230. Whoo. Here. What. Matt. And. That. Anyone. See where that arced I always. Wear PPE. Unlike. Us. Well. We hope you guys enjoyed the video this has been a project that lot of you guys have been asking for for a long time, so it's awesome to check it off that long bucket list of projects we wanted to complete now, you might be wondering it. Didn't seem that powerful, and to, be honest that's because we did actually have to constrain, the. Design to, limit. The firepower, of the railgun to make sure it fell into the classification, of an air gun and not an actual firearm and that's because in Canada we have strict gun control which. Means we didn't want to make an illegal firearm because, making a video isn't worth going to jail over. Or. Is, it. No. No it's not but, if you guys want to see us take on more big projects like this make sure you support our sponsors, like this video sponsor, world of warships check, out the link in the description below for some awesome bonuses, plus. If you guys want to own a part of this project we're actually gonna be auctioning off a few of the. Bullets. We're gonna be offering a few of these projectiles, on eBay, check out the link in the description below bids, start at just one dollar thanks. For watching.
