0:20 This is a coil gun (Gauss cannon), it's very different because it uses the single force vector created by the coil you'll show later in the video. It's easy: if it has wire going around the barrel it's a coil gun, if it has wire on the back only, and a hollow rectangular barrel section (formed by the rails and the bullet containment) it's a rail gun
In 00:30 the gun shown is a Gauss gun aka coil gun not a rail gun. Its a completely different system, gauss gun uses a series of electromagnetic coils that activate in a syncronize order do propel the projectile. In a rail gun the projectile completes the circuit in between two rails, one rail being + and the other being - and the positive rail is fed by capacitors. This generates a huge magnetic force that pushes the projectile. Two completely different systems.
Rail Gun and Gauss Gun are two completely different types. Rail gun uses high voltage and two rails, with the projectile being conductive. Gauss gun uses magnetism to pull the projectile through the center of each coil.
I wonder if we'll see more of the coilgun start to overtake railgun interest. IMO the main issue of the coilgun (synchronized switching and stabilizing the round in the magnetic field) is a *lot* easier to overcome than the rail ablation issue in railguns. Apparently the Chinese Navy has gone down the coilgun route and is test-fielding a naval gun? Research follows funding, so I guess we'll find out once the check-writers recover from the failure of the US Navy's railgun program.
From my research, they haven’t been able to create a rail gun that doesn’t tear it’s self apart after shooting just a handful of rounds. That’s why it was created awhile ago but is still not in service.
Looks like the guy in the video doing the pointing, the guy with three arms, needs a bit more time in the cloning tanks. He doesn't appear to be quite done.
It should have 2 separate adjacent barrels. 1 barrel for the projectile and 1 barrel for linear motor, so that heat from linear motor barrel doesn't affect projectile and its barrel. Both barrel has lateral opening. Linear motor pushes metal that has leg in projectile barrel to propel the projectile. This will be fine as there is no explosive propulsion in projectile barrel. Projectile barrel can have holes to dissipate friction heat
@@randompeople7595 barrel inside barrel is too complex and expensive. It's simply 2 adjacent barrels with lateral openings to allow leg of moving conductor in conductor barrel to push projectile in the adjacent barrel. (*===+> ( : propulsion barrel * : metal conductor in propulsion barrel === : the leg of metal conductor + : the projectile > : the projectile barrel
It's not friction that's destroying the barrels. It's the dead short created when 25 MW are applied to the conductors with the projectile contacts closing the circuit. The (nearly) instantaneous surge melts and vaporizes portions of the rails.
I'm fascinated with the idea of railguns. Not just in sector of warfare but multiple other applications such as launching rockets for space exploration or like powering trains using railguns so it can get to it's destination faster
The maglev system used in Changai is essentially a giant coilgun, different principle that a railgun. but if we can solve the ablation problem of railguns then a railgun train would be far cheaper to build than a maglev.
Railgun uses 25MW as much as a lot of households uses.. Yeah in a split second. And the principle used in the past was different then used today. In the past they used coils, now rails. Only the magnetism is the same as being the propellant force.. So..
@@maalikserebryakov he said "yeah, in a split second" as if the houses used the same power in less time, which has no sense since as I said power has time in itself. He might wanted to say energy but no one talked about that
@@kino_61 25 MW can be provided by caps. When they contain 1 kWh=3.6 MJ of energy, discharging them in 1/8 s will roughly amount to 25 MW during that time. Just a couple of cents worth. I think we all agree on that.
It fires a projectile at very high speed much faster than a conventional artillery gun. At that speed, you don't even need gunpowder as the velocity of the projectile is enough to obliterate the target. This also gives it a high range. Only issue is that the heat produced literally destroys the barrel and cannot be re-used anymore.
@@derekpierkowski7641 you really had what i said fly over your head huh? also dynamic powder charges are still in the shells class. the "shells" in terms of artiliery refer to the projectile its self, not the casing. its why dynamic powder charged ammo is still called a shell when it has no case and is instead fired raw in the barrel... 5iq...
That is a big misconception. Current flows from positive to negative, always. Electric current is not the same as "electron flow". It can be a flow of electrons, positrons, ions or any other charged objects.
@@atmacm It absolutely does not. You either did not read what I wrote or have reading comprehension problems. Repeating same false statement and adding "absolutely" does not make it true.
@@qewqeqeqwew3977 I read your response, but it’s wrong. Did you not read my comment where I told you accurate information that you could learn from? Apparently you didn’t. Current flows negative to positive but it’s mostly taught to be the opposite to not confuse people…. Like you
The mechanical voice is a turn off & the script excludes important details. For example, the voice says to use a hand to determine what direction the magnetic field follows the around a wire but not which hand. Thankfully, the video shows the right hand.

forgot to mention the barrel quickly tears it's self apart and you cant use it repeatedly without changing the barrel internals ?
you would need to replace the rails every few shots. not particularly difficult, but still an additional limitation.
Yup, it's too strong for itself
Not the new ones

Dude your content is awesome! 👍
Cool. I found one on craigslist and I wasn’t sure what it was
Lmao
2:30 This could easily be improved by using an electromagnet to establish an external magnetic field acting on the projectile
They probably already know it’s
Great channel, glad i found it

Which makes sense. The projectile need to be touching both side at all time, for the current, providing a lot of friction.
Very nice, it explains a lot
0:22 - coilgun...
Excellent
Looks like the guy in the video doing the pointing, the guy with three arms, needs a bit more time in the cloning tanks. He doesn't appear to be quite done.
25 MW are only needed for a brief time (during acceleration) and can be provided by large capacitors.
the picture from around 00:17 to 00:25 shows a gauss gun not a rail gun... just saying
Certainly a certain scientific railgun
And thank you

1 barrel for the projectile and 1 barrel for linear motor, so that heat from linear motor barrel doesn't affect projectile and its barrel.
Both barrel has lateral opening.
Linear motor pushes metal that has leg in projectile barrel to propel the projectile.

Draw this. Can't picture what your saying
I am picturing a barrel inside of a barrel in which the first one inside holds the projectile and the latter outside accelerates the projectile?

25MW? GREAT SCOTT!

I would like to know more about the rail gun project from Germany, does anyone know the name of the project?
The problems Germans had in WW2 with railguns didn't get solved.
Actually, electrons flow from - to + in a battery. You’ve got it backwards.
He's talking about current which moves + to - so he's right
The gun that you show about in the beginning looks like a Coil Gun, or Gauss cannon, not a Rail Gun
1:25is a mistake. It should be the left hand.
i thought it was the right hand rule ?
umm, soo, which country are you invading with it?
"Do you know what could penetrate this armor?"
sorry guys idk really know about a railgun
How do railguns taken consider curvature of Earth when you do your your math where's the to go when it doesn't account for
That's why I came here for. Flat earth
Like what is the rail gun for is it more powerful than gunpowder?

it makes some guy rich and takes money from the slave class so it served its purpose.
Zumvalt destroyers are taken out of use, no ?
they stopped the production at 3 ships, since it's too costly to make. So they've designed a new destroyer.
Ya lost me when ya said it fired shells.
you do realize that all artillery use shells, right? my guy out here thinking shells only apply to shotgun ammo.
