How is the fire that you see in the video generated? I thought it was entirely electromagnets. Pretty awesome stuff though! We thought about making a scaled down version in our sophomore design class.

Yes electromagnet...should've added the link prior. Sounds like an interesting college life!
Lol it looks like they are shooting piston rods.
looks like they could be :P

heres some closer shots of the projectiles and workings of the gun
Wild!!!!!!
Oh yeahQuote:

Plus, they're throwing 33 megajoules of electricity into that son of a bitch... or 33kw-hours into i,t in the space of a split second, which equals a LOT of heat that has to go somewhere!
Time to recommission the Missouri :D
That's awesome. Considering how small the projectile appears to be, I wonder how the energy compares to that of a 16" gun. As I recall, the retired Iowa class battleships remain by far the most cost effective way to deliver a pounding.
My favorite quote in the youtube comments:
Poorly paraphrased, but close enough. :DQuote:

A rail gun is a gun that does not use explosives. It takes a metalic object and uses magnetic fields to propel the object forward. You can imagine it as a long barrel with a moving magnet (not actually, but instead coils), as the object moves forward, so does the magnet, and it keeps pulling the metal object faster and faster until it reaches the end of the barrel and it is shot.
Now i'm sure there are different methods to get this done, but that is the basic idea.
Almost right, the whole barrel, or parallel plates in a rail guns case, is composed of magnets. If you know how a maglev train works then you know how a railgun works. the magnets rapidly switch on right before the projectile gets to them and off as soon as it goes by, propelling the projectile forward.
I should have said magnetic force. And yeah, I should also say that besides for the projectile, I do not believe there are any moving parts.
Each shot must produce a lot of heat. So I wonder what the max rate of fire is and if the heat limits number of shots per minute?
I think they're planning on ten shots a minute from the article I read.
That isn't fire. It is the air behind the supersonic projectile turning into plasma.
its actually alot futher along than this video shows we already have front mount turrets developed navy just doesnt want to buy them yet(i think atomic energies is the company that has made the cannon)
also the projectile is non ferros and is pushed by a ferros metal plate kinda like a SABOT round the nick projectile moves so fast that it seperates the atmosphere infront of it cuaseing engouh friction to set it on fire as it travels
also the range is based on power put in and can be give a ballistic trajectory for short ranges or for curve of the earth effect to hit a target at sea past the horrizen
for those interested projectile is still accelerating at the point of any ballistic weapon when it hits its ballistics trajectorie fall path start
also the damage does not come from the projectile being shot but the impact force behind it, it would go through a ship from foward to aft and continue if shot at full power
also it would require a nuclear reactor at this point in time to be and effective and quick repeating shot weapon
there is a massive wearhouse full of capacitors to power the one shot in the video.
That is a coil gun.Quote:

Then an electromagnetic field is produced and rapidly accelerates the projectile outward while the field follows the projectile down the rails till the circuit is no longer complete.
And yea, the flames are plasma, and parts of the projectile that is touching the rails that are vaporizing.
coil gun = same thing as a solenoid basically right? just it doesn't stop it before it shoots out the endQuote:

The biggest issue with railguns is the immense heat, and the possible damage to the two rails.
No no no no.
You place a conductive material across two "rails" or two leads - one positive one negative. You introduce a magnetic field perpendicular to the direction of travel and the current flowing through the conductive object causes the object to move as described by Faraday. I'd go into further detail, but just look it up. Instead of allowing the current source to provide motion to the projectile, you could apply force to the projectile and force it in the opposite direction and you now have a linear DC generator.

Who was the no no no no directed towards?
Good diagram to explain for those that have no idea.
