- A high-speed camera captures the first full-energy shots from the Office of Naval Research-funded electromagnetic railgun prototype launcher that was recently installed at a test facility in Dahlgren, Va. The test shots begin a month-long series of full-energy tests to evaluate the first of two industry-built launchers that will help bring the Navy a step closer to producing a next-generation, long-range weapon for surface ships. The new launcher brings advanced material and high-power technologies in a system that now resembles a large-caliber gun
I can't be sure, but I think the wobbling visible at 0:34 occurs after the projectile has already punched through the concrete barrier. Notice in the following scene how close the barrier is to the tunnel mouth, and how no barrier is visible downrange at 0:34 ... my guess is most of the wobbling is due to a deformed projectile, although the projectile being loaded at 0:12 certainly doesn't look very aerodynamic.
@LordMertables yeah thats just a test round to give the gun a realistic load to work with. The main system under scrutiny is the power delivery and the shape of the EM field being used to direct the projectile, much like the rifling in a cannon.
I hope the damage doesn't get nerfed. Maybe we'll get selective damage types now, too. You know, explosive or EM.
@PhantomBoku In real life, railguns definitely DO NOT need a buff.
Game over.
@24680kong 33 Megajoules. A one-ton truck travelling at 100mph is equal to one megajoule of energy.
Holy crap here come the space movie/game weapons
@M3g4t0n The projectile ablates at the speed it travels, causing a fireball. Don't you ever watch stuff about rockets or the space shuttles?
@BFGoodwrench3 it still takes a crapload of power to even get a standard bullet sized projectile up to antipersonnel speeds. Try watching some videos of peoples homemade railguns, they have capacitor banks in the 70lb range that when charged cant even get a round to shoot 100ft. Now say it was military tech though. Is it really effective to have a soldier running with 50lbs of capacitors and their gear. And they can only get 1 shot off before having to spend several mins recharging?
Why all the fire? It's just an electromagnetic wave device, propelling a metal slug, right? Then why all the combustion?
And here people thought this was fake in Transformers 2 lol
THE GALLENTE BRAH!
damn you thomas edison!
While lasers look cool.... looks like high impact/velocity projectiles will be dominating for awhile longer. Only advancement here is new ways to slug large quantities of metal at insanely high speeds.
@atrolle1100 You do notice the big BAE logo slapped on the side, right? No need to thank father just yet..
Sincerely,
a Briton.
@M3g4t0n I'm talking about re-entry? Herpaderp?
@UseLogicPlease123 They always will when it comes to kinetic based impact (aka armor and hull)
Development of weapons is never a waste of money for the US. If it weren't for the massive imbalance in force projection, the west (Europe included since NATO and the UN rely on US military might) wouldn't fare so well when it comes to diplomacy with places like Russia and China. Also you are quite incorrect that the US started all the wars in the last 40 years. The only war we started alone was the latest Iraq war. The rest were responses to attacks or requested by allies or the UN.
And when you get to that point, all your doing is making the projectile a significantly less effective existing bullet/shell combo. Dude, get over it. you aren't getting a hand carried antipersonnel railgun anytime soon. I know, I've tried making one. I went through that phase too. I could lob an aluminum projectile about 40ft (after testing) with my gun and its 25lb cap bank. Beyond that, either A the bullet would melt in air, of B Id break a cap cause collapsing magnetic fields can damage them
how would they recharge them in the field. Is everyone gonna carry aroudn a little generator (more weight) to do it? I guess the only real Idea would be to have each projectile built in with a powerful capacitor made to make contact with the rails. So the gun would only be 2 rails and a trigger that pushed the projectile into the rails, so the cap made its contact and charged teh rails for the actual firing. That still would require making a massive projectile to carry all the power.
@BFGoodwrench3 You clearly have no idea how a railgun works. Lemme put it to you this way - a railgun sized to be carried and operated by a human (think a single-use anti-tank rocket launcher) would generate so much more heat than you could properly sink/dissipate with a unit that size, that you would be cooked to Well Done by firing the unit. And that's ignoring the fact that powerplants strong enough to launch your ammo do not exist in human-carried size.
Several effects are working here to create that explosion.
First, as stated in a comment, is ohmic heating, created by the current through the projectile.
Second, the speed that the projectile is coming out of the barrel is high enough that the air around the projectile basically combusts, much like the space shuttle re-entering the atmosphere.
Third, there are layers of metal that are vaporizing off the projectile from friction.
The speed record for this thing was slightly over Mach 7 (2520m/s)
@BFGoodwrench3 The purpose of them doing it in teh sense of a turret for a ship or something is that it can be fed by the ships reactors for power and has lots of space for capacitor banks and cooling systems. Railguns are hardly an effective hand carried weapon right now because it requires way too much energy to fire. And FYI railguns coilguns and "blaster"s in teh real world sense all require ammunition unlike in some videogames.
@gecko1986 Railgun/Mass driver technology has been around for a long time, however it hasn't been practical in a military sense due to the stresses upon the metals involved. This project has made a weapon that can fire frequently. Whereas most materials if they are subjected to frequent firing, warp and twist the metals involved.
Protip: Flush the barrel with Helium gas and install a business-end port to the other side of barrel which will open just before the firing. Just make sure that "AND" is hardwired _Real_ _Good_ so that the mach 7 thing wont hit the port. :)
Benefits: no sparks/fire cloud and reduced wear of the barrel, and lo and behold the projectile will be even faster.
@kschleic9053 The test 'Slugs' are designed to rapidly slow down so that they are able to use less real estate for testing at full power.
"The rounds we are firing currently are non-aerodynamic slugs," Ellis said of the testing. "They match the interior ballistics of what the launcher is expected to see but are intended to slow down quickly."
@herb420ful Well this'll fix that nicely. Punch a hole clean through a battleship at a couple miles (at least). Did I say clean? I meant explosive and very messy. And by messy I mean giant entry hole, blood and shrapnel everywhere... I think the term is "deterrence by force of arms".
Fake 0:43 Sorry to burst your bubbles, but if this is real, that is great. But after this I've lost my belief due to the fact that in this time-stamp there is another screen crappily placed over the facility's logo, and you can see it ripped and draping down on the ground. /troll
@LordMertables
the Idea of Electrically charging to produce a projectile is a rail gun... That is all
the theoretical speed of one is about as real as Hologram technology being portable and not needing a screen
@thatghillyguy Dude, you need 1. oxegen (which there obviously is) 2. something to make fire (propelling something at that speed create a lot of friction so check) 3. a combustible material which isn't present if it's a pure electromagnetic cannon!
@DannleChannel Check what Dangemb said, nothing to do with atmosphere igniting!
1 of the 3 key elements of creating fire is missing so stop calling my bullshit bullshit before getting your facts straight!
@Moresti1 The overlay is more likely to cover information that was on the original target that could not be released to the public as it pertains to an ongoing and, I'm 99.9% certain, classified project.
I'd imagine that would be relatively easy to implement, either through something similar to riflings, or possibly fins on the projectile. I believe the current main issue is heat dissipation.
@TheBetterGame The round is accelerated in the space of about twenty feet to well over Mach 5. The friction and air resistance has thermal effects, such as is evidenced by the film.
actually it would, its supposed to tear through things not penetrate straight through. having it odd shaped makes it do more damage, it has the force to penetrate as is.
@KataTurbo in terms of direct neighbor the US has NORTH America in the south, namely Mexico. Otherwise you could say that they as well have Greenland and Africa in the east.
@TheNickyYo Unfortunately he's right. There is some editing in the video. While i still think it's all entirely real, i'm interested to know why they edited the footage.
@dangemb I knew I wrote it wrong... (English isn't my native language)
Sorry, didn't knew that. Thought I was a pure electromagnetic accelerator :)
@centers46 - Wouldn't doubt something like that in the future, right now I think the focus is centered on the energy required to fire this awesome weapon.
rail gun is not about aerodynamics. its about throwing projectiles with the force to rip throught anything. The projectile can be of any shape
Nevermind.....read the comments. RUclips fail. Trust me,vin walk into Chinese restaraunts and ask for pizza too. Its nit at all diddy's for mw.
@LordMertables It's a projectile they purposely made non-aerodynamic so it'll fall to the ground rather than leveling a building in a nearby city.
@melikai187 Curious enough to read some of the earlier comments? Or just curious enough to post a comment? Not trying to be rude...just wondering.
but aerodynamics will still be effecting the round's deceleration though air, it cant be a disadvantage to make it aerodynamic
@Moresti1 You know that's the other side of the wall hanging down on the other side right? It had the logo on both sides.
@antguy I found what I was looking for a few minutes afterwards. Sometime I do like to pot for the hell of posting ha
@M3g4t0n That amount of acceleration involves so much energy it ignites the atmosphere behind it. People should do some research before they call bullshit...
@aaron8862006 Its not supposed to fly well they want it to fall to the ground quickly for this kind of testing.
The projectiles are suppose to be guided (somehow) as well allowing accurate shoots from 100-150+ miles.
Seems like they need some way of putting a spin on the projectile to help keep it from wabbling down range.
@anotherMrGr33N Blasters also propel an object with electromagneti forces, so it is the same concept.
@Moresti1 Also, the facility looks real and the gun does too, but that screen is really unnecessary.
@TheBetterGame
It's not combustion, it's vaporised metal from ohmic heating. Think arc welding...
I like how it says "Abort!!!"
I'm curious why would they use such a blunt tipped surface vs a pointy tipped one?
@shurnui Gallente=Blasters (and drones)
Caldari=Railgun (and missiles)
How fast is the projectile moving?
@RayneAngelus Result: Tank destroyed and meal for the whole platoon
@drinking12many Thanks for agreeing with me? Waste of server space.
Railguns are shit. Lasers are the way. I want my Scorch crystals.
@KossyHasNoTeeth Caldari are rail users. Gallente are blasters.
Electromagnetic railgun with fire nozzle flash
Looks legit...
This technology should be used for mass drivers, not guns.
Why is there an explosion if its charged via electricity.
@KossyHasNoTeeth no, actually Gallente ancestors are frenchs from the Tau Ceti system. Americans are representated by the Amarr Empire and some Matar tribes.
EvE is real
Old news, ive used that shit back in 2004 on my Moa...
Anyone know how much power this thing just used?
I find their software intuitive and rather amusing.
Interesting, Now how far could it fire a chicken?
@aronchai Errrr... A railgun IS a mass driver.
@DaFreemanPHD "When will then be now?" "Soon™."
@shurnui Gallente use blasters, you should talk about Caldari, who are the real railgun users.
@navyrayne
nah, just spreading some hate :P
that round was not very aerodynamic O_o
Press 4 for terrifying/awesome sound.
my eagle needs a new set of railguns.
@RayneAngelus they do not exist yet
@dooleybobson1 FUCK YEAH
New breed of BattleShips anyone?
Ahhh the future looks so pretty!
@LetFr33DomRing
Not sure what a railgun would do against terrorists but yeah, cool gun.
Looks like america is gallente.
I always felt the US was Caldari
The Gallente are coming...
doesnt look very accurate
@PhantomBoku
IS REAL
EVE.
@ZSa7NBuA Impressive you managed to offend about 90% of the population in under 15 words...and you managed to exhaust most of the words stored in your expansive vocabulary...I am impressed.
BTW, I don't have health insurance, but like every American I do have access to healthcare. And I am glad my tax dollars are being spent on this project, even though BAE is a British company...
suddenly: Stargate
Ich dachte die Amis sind pleite?
@PhantomBoku rails = range :D
@BFGoodwrench3 You clearly have no idea how a railgun works. Lemme put it to you this way - a railgun sized to be carried and operated by a human (think a single-use anti-tank rocket launcher) would generate so much more heat than you could properly sink/dissipate with a unit that size, that you would be cooked to Well Done by firing the unit. And that's ignoring the fact that powerplants strong enough to launch your ammo do not exist in human-carried size.
The Tau!
@thatghillyguy Uhu, I do and you know what? Those are powered by using rocket fuel. You know, that stuff that combusts and causes propulsion?!
