Navy Tests Electromagnetic Railgun 美國海軍磁軌砲試驗

[Noancrux]

This weapons projectile is unstable. The pointed version would obviously be most accurate. This is equivalent to firing a 22 cal. with a 50 cal. casing on the back. Unstable. It says 7 times faster than the speed of sound.

[Theantiboss]

Okay you have the rail gun, now make the Metal Gear

[AKxx47]

why is there an explosion? I always pictured a smooth silent launch. Is this real?

[Mech87a]

@AKxx47 Reading the description of the video i would guess that the fire i caused by some serius friction and the sound is caused by breaking the sound barrier...

[poisonarrow8]

@AKxx47 you can't launch it silent. When you break the "sound barrier" you will hear it. This "thingy" travels at about 5-7 times the speed of sound

[Thekentkennedy]

Alright, now wheres the Gundam this goes on?

[MrPritorius]

Holy Jesus!



[M0rbidfl0rist]

@lalanmonkeydude ...i think that one may have gone right over your head

[DHLaShomb]

Projetile goes fast, GREAT it takes 2hrs of setup to fire lol. I cant believe this is as far as this project has come.......been around a while now.

[rdallas81]

Just imagine the stuff we DON'T know about..... Those "ufos" people see, umm let me clue u in on a secret....WE BUILD THEM HERE!

[jackalack93]

not quite the same as quake 3 arena though is it...

[Stalker6622]

wow 

[slorta]

even the sabot would go through a tank

[openarms332]

and in 10 years we will have handguns like this:D

[Clint945]

@openarms3

They already exist, search 'coilgun'

I made one last summer, quite cool little things.

[openarms332]

@Clint945 I know about coilguns. They are nothing like what i was talking about. im talking about one that is the size of a handgun and sends projectiles just as fast or even faster than the one in the video.

[Clint945]

@openarms332

Won't happen i'm afraid, the energy required for that would be prohibitively high for a handgun.

Besides, there's not really any improvement over small arms to be made with this technology.

Its major benefit is in the extra range that these weapons can achieve, that's not really that useful for handguns which are generally used at short range.

Sniper weapons may have an application, but again, i don't see much of an improvement to offset the cost.

[openarms332]

@Clint945 You have no idea what type of power cells we will have in the near future. Nuclear fusion cells are a possiblilty and they would put out a lot more energy than that machine. Also higher velocity rounds mean more stoping power. In fact if we could get the rounds to go as fast as this railgun can fire than we could use projectils the size of grains of sand and do even more damage. I go shooting everyday. smaller and faster like the 5.56 does more damage pluse bigger magazines!

[Clint945]

@openarms332

I would say i have a pretty good idea of what power cells will do in the future concidering that i'm an astrophysicist with my speciality being in nuclear power and rocketry/propulsion.

Nuclear FISSION cells already exist and do not produce enough power per unit size to allow for handhelds with that energy, besides they're dangerous to handle so why would we have them in a handheld.

Nuclear FUSION on that scale is hundreds of years away if we ever decide to make it.

[Clint945]

@openarms332

Also, nuclear Fusion produces energy relative to volume, so your energy is relative to length cubed, while fission batteries is energy related to area, so energy related to length squared.

so actually fission batteries is better for smaller applications anyway.

Higher Velocity rounds does produce more stopping power, but it also increases recoil for the same size of round. so, to achieve what you want... handguns would have dangerously high recoil.

[openarms332]

@Clint945 Isn't it funny how one sentence got to all of this? I guess the only thing that we can do to solve this conflict is to wait huh?

[Clint945]

@openarms332

heh, guess so.

The larger guns are very useful and i personally want to see them used to launch cargo into space.

[openarms332]

@Clint945 they acually have tryed that with so called "space guns" they launch objects at supersonic speeds it pretty cool!

[froggytv]

My left ear loves this.

[dan6896]

HOLY MOTHERFUCKING SHIT. 0.0

[trultima]

BFG

[digimaks]

oooh, next making electromagnetic canon on a tank. only thing sucks, it will need a huge battery trailer :)

but, jeez, look at the size of that thing! Now we know where our hard-earned tax money get wasted...

[BassPlayerGuy123]

wheres the free electron lasers cmon U.S we know you got em ;)

[bolt3226]

and this is just the one thay can to show you.we all know theres one way better hideing in a test lab somewhere......but thats most likely classified.

[AirCommando12]

atleast specify wich navy?

[KDLBlood]

@AirCommando12 US Navy

[AirCommando12]

@KDLBlood ty

[EliteOfTheRad]

if the description says that this weapon doesn't use an explosive charge, then why do i keep seeing an explosive charge when they fire that thing?

[shoeprich2012]

@EliteOfTheRad The projectile moves so fast that it ignites the air around it. Try 6 km per second

[shoeprich2012]

@shoeprich2012 The boom is the sonic boom

[kdc43]

@EliteOfTheRad Not an explosion but the plasma arc being forced out with projectile, it happens really fast. It just looks like an explosion.

[TheMightyZwom]

@EliteOfTheRad

It works with both high voltage and high current. So it produces a really huge amound of hot plasma - that's the explosion you see. And the explosion is NOT the reason for the bullet to fly away, it's just a side-effect.

[EnigmaHood]

@EliteOfTheRad Friction creates heat, thus you see flames. I thought that would be obvious.

[BigRolando]

these are being designed to go on ships. the reason we want to use these is a tomahawk missile costs about 1.5 million dollars metal rounds are cheap. and you have to think of the energy delivery of this thing. the plan is to shoot a 155mm round which weighs about 75 lb at over 7000 feet per second.

[dweckman90]

What is the point of this? It just looks like a big bullet.. wouldnt it be more effective to use a missile?

[EnigmaHood]

@dweckman90 No. A missile costs several million dollars. If you think about it, a missile is basically a vehicle that sacrifices itself to destroy something else. If the thing it's destroying is less expensive than it is, then it's not cost effective. A railgun's projectiles are dirt cheap in comparison. A railgun can also carry a lot more ammunition to destroy more targets. It's also harder to shoot down, and is typically more effective in direct fire situations.

[dweckman90]

@EnigmaHood ohhhh... makes sense.. thanks!

[MeanTerminator]

Too cumbersome for the battlefield. But a great way of sending stuff in orbit like sattellites.

[TheMightyZwom]

@MeanTerminator

I think that would be a really bad idea... It does not only use a high current, the current also has a high di/dt, that means, it will induce a high voltage in any circuit, like an EMP. So, if you shoot a sattellite in space with a railgun, I'm pretty sure, all it's circuits will be killed, before it even leaves the cannon...

[sdagoespro]

Now... where is the supressor for that thing?

[MarsuveezBlack]

energy can easily be supplied to one of these if mounted to a U.S. carrier with it's nuclear reactors or hydrogen full cells also work, using a system of instruments that work with the water around it on any battleship. plus the cooling process can be done rather easily, theres lots of water in the ocean.

[malkooth]

How many amps does this bugger use?

[jdm1066]

@malkooth I have heard the Navy ship mounted ones requiring more than 5 million amps.

[malkooth]

@jdm1066 What a giant series of capacitors?

[TheMightyZwom]

@malkooth

I think they won't use capacitors for this in the future. A much better way of storing huge amounts of energy and releasing them in a short time as an impulse-current is the "compensated pulsed alternater", also called "compulsator".

[BigRolando]

@malkooth well its supposed to make 33million joules of energy soooo alot. I can't do the exact conversion cause i dont know how many seconds it makes the energy but for 1 second using a 440 volt system its gonna be about 75k amps

[kmofoshomyho]

why fuck do none of these videos show the projectile hitting the target????

[martinaee]

@kmofoshomyho My guess is while these are in development (if they even ever become actual real-life weapons) they don't want anyone including other countries to know damage potential of said weapon.

[hext616]

@kmofoshomyho because they are not real!!!!!!!!!!!!!

[4greaterevil]

@kmofoshomyho oops i1q_rRicAwI

[leavingjupiter]

@kmofoshomyho

'cause it never stopped. To this day it's still cruisin...

[lasourisaboyante]

@kmofoshomyho There are plenty of them showing impact. Your incompetence is your problem.

[BStanley346]

@kmofoshomyho seems like those issues could be solved with either a nuclear power source or a massive amount of water to dissipate the heat. Not sure where you would find either of those on a military ship though.

[lalamonkeydude]

@BStanley346 Both of those are found on nuclear submarines, I think you can fit them on a ship...

[interpim1]

@BStanley346 your being sarcastic right? There are several Navy ships with nuclear power and they float in copious amounts of water.

[skylineaddict]

@BStanley346

I see what you did there!

[kytanosable]

@BStanley346 Don't some submarines have on board nuclear power plants?

[zedd81]

@kytanosable *facepalm....

"sarcasm" look it up.

[kytanosable]

@zedd81 Ah, yes. I do tend to take thing's a too literally at times.

[bradtheimpaler37]

@BStanley346 haha your joking right?

[PuttAHsockinit]

@kmofoshomyho because that sir... is confidential.

[TheTVTasterLOL]

@kmofoshomyho At 1:57 They showed you projectile Target penetration...

[Fulou]

@kmofoshomyho /watch?v=fhBIZF35rSM

[cunijoeme]

@kmofoshomyho im not sure there is one ?

[soulman902]

My luck I would be out in the field in front of that thing.

"What's with the sirens....."

[minecraftfan01]

2:20 whats with the windows?

[360Freakoutkid]

@minecraftfan01 vents

[DarthElius]

Well that rail gun of theirs is completly useless. That is unless they have that building on wheels and can actually aim side to side and not just straight in front.. It'll be many more years before that weapon will be able to have any real world applications.

[Donish1786]

@DarthElius you have to start somewhere. #prototype

[FoxvoxDK]

@DarthElius These massive guns, like the massive guns on old battleships are just for that, long range, high energy impact purposes. These guns will most likely see first uses on nuclear ships.

[manishy1]

@DarthElius It's for the navy, you mong....

BOATS AND SHIT. It's also a prototype.

Anyways, onto more normal things, does anyone know if this weapon is practical for use on (attached to) aircraft? Is recoil generated by the weapon? Could smaller versions be designed for firearm use (with the help of small super-capictors, obviously)?

[Thetarget1]

@manishy1

Well it has recoil. Everything has. It's Newton's third law.

[akamahi1]

@manishy1

hi

i think it´s not made fore using it somewhere else than in boats because the

energy you need is huge !!

and also the weapon gets unbelievealble hot !!

LG

[haloded]

@akamahi1 u can make 200v with a 9 volts batery, imagine 120v or 240v to 50000v or more

[dlstb]

@akamahi1 Are you forgetting that a percentage of our boats are powered by nuclear reactors capable of providing a city with power and water for a decade?

[wackywankavator]

@manishy1

No.

Yes.

Probably not.

You're welcome. :)

[wackywankavator]

@wackywankavator

Oh, but look up Coil Guns on youtube or wikipedia. They've got some personal use air coil guns that have about the same push as an airsoft gun. Cool stuff. :)

[TheMightyZwom]

@manishy1

There MUST be recoil! Just look for Newtons third law on wikipedia!

[NitroDSP]

i think one of their regulators blew and the apparatus projected the harpoon with only 1/3 of its magnets. I can only imagine if they used more resilient components.

[Jomasterhns]

im thinking soon they are going to have massive land based rail guns that can lob a 100+ lb object over 10 tims the speed ov sound, im also looking fowrd to the halo mac

[EmpyreanMachinima]

So I see that the Navy is planning on making a Halo MAC Gun. Well done.

[aserta]

@EmpyreanMachinima LOooong time until those guns will ever be matched by irl tech.

[TheMrBlinx]

Something about half way down that thing ozoned out. I'm sure a massive spark dump is not part of the plan.

[calvin228855]

I heard a Japanese girl called Misaka Mikoto could do a similar thing as the video did with only 100yen

[LuisReefTank]

@calvin228855 And also a nun that can store any book just by looking at them once.

Obviously such a process makes her be hungry 85% of the time.

[Deses]

@calvin228855 What a waste of money. :(

[ad1das97]

cool



[SHOTGUNPSYCHOLOGY]

It looks like they are a few years off from a truly functional design. seems that there is a massive excess of electricity being pumped into that array, which is causing capacitor to overload.
