In the United States began to develop a portable railgun

The US Navy received the necessary funds and began to develop a portable railgun, the caliber of the new is already known weapons - 12,7 mm, reports Rossiyskaya Gazeta with reference to the Military.com resource.

“Railgun of such a caliber will significantly exceed the power of its powder“ colleagues ”, however, it is not clear how scientists can solve the problem of feeding this weapon - indeed, even for one shot of such a gun you need a huge amount of electricity,” the newspaper notes. .

The newspaper reminds that American designers have been working on the implementation of the railgun idea for several years. The first project in this area was the ship's railgun, which is planned to be installed on destroyers from 2020.

Similar developments are also being conducted in Russia.

“In our laboratory tests, the maximum speed (of the projectile) reached 6,25 kilometer per second with a mass of projectile of a few grams. This is very close to the first cosmic velocity, ”Alexey Shurupov, director of the Shatura branch of the Joint Institute for High Temperatures of the Russian Academy of Sciences, told about the tests of the railgun Artsimovich.

Help newspaper: “Railgun is a pulsed electrode mass accelerator. It consists of two "rails", connected to the source of electricity and arranged in parallel. A projectile is loaded into this structure, after which the electrical circuit is closed, and it starts moving perpendicularly to the movement of the current and the lines of the magnetic field of the Lorentz force. ”

Well, they’ll cut the loot, where without it, but both the computer and the Sotiks with smartphones were in the realm of fantasy, and now ordinary things, so who knows.

Well, if you call a bullet a shell, and portability means the size of a one-room apartment ...

And a rate of 3 shots per hour ....

Immediately equip the entire American army with this technique !!!!!!

[Maksus]

The problem is that the small "bullet" of the railgun, when hitting the target, will give off such an amount of energy that it will be comparable to the hit of a howitzer shell. Just right in the bull's-eye. Remember the large-caliber artillery systems of the Second World War, they, too, were not small and rapid-fire.

[dvina71]

Quote: Maksus

The problem is that the little "bullet"

The problem is that a small bullet will not give all the energy, but only a part. An equal product of mass and a drop in speed, per unit of time .. Simply put ... a projectile that has a specific shape for moving with hyper speed will simply pierce the target without causing damage to it.

.. not quite right .. our Pundits here managed to shoe a flea .. just watch the 7 minutes video from 2009 .. very simple and intelligible, as always Russian elegant solution ..

[Nikolay K]

At these speeds, the projectile, as a rule, flies into dust when hit, and if not, then this is easy to achieve, the technologies are developed. So most of the energy will reach the goal. And if we recall that the kinetic energy is proportional to the square of the speed, and the speed of the projectile fired from the railgun is an order of magnitude higher than the speed of the projectile of the firearm, it turns out that the projectile of the same mass fired from the railgun carries 100 times more energy .

[Nitarius]

))) Our first mobile phone actually ... was made in Moscow!
and much more . But here is a clear cut!

[Azitral]

The computer and sotikas with smartphones were made to get rich on sale. Strategic Defense Initiative and "thousands of scramjet missiles" to cash in on development. The difference is fundamental. "The king has a lot" - it was not invented in Russia. A classic British proverb. They drank the budget in percentage terms, maybe less. In absolute terms, there will be more. There is something to cut.
And as for the railgun, no one says that it’s fantastic. For ships with nuclear weapons - why not? And not much energy is required. The problem is to QUICKLY release energy. Creating high POWER. This is still very cumbersome.

[Vadim237]

For the rapid release of energy, supercapacitors exist.

The technology is at least quite real, unlike the laser wunderwuffel. And together with the "sawing the dough" (where can we go without it?), Not only technological experience will be obtained, but also recommendations and methodology for military use will be developed. Which is not good news.

[Basarev]

An explosive magnetic generator is not such a fabulous thing, and the dimensions and mass are almost equal to those of a large-caliber tank shell ... So the idea of ​​a portable railgun of 12,7 mm caliber is not so utopian. Current ... It is necessary to reduce the size and mass of explosive magnetic generators.

[dauria]

after all, even for one shot from such a gun, a huge amount of electricity is needed "

you can compare the store from 5, 45 ak with a battery
Bullet weight, g: 3,3-4,1
Initial velocity of the bullet, m / s: 900
Bullet Energy, J: 1316
Horn release energy 30 pcs - 40 KZhD

The energy stored in the Li-ion battery for a portable video camera or laptop with a capacity of 10 a * hour (3,7 v * 1 A * 36 000 sec) = 133 kJ.

In principle, it is comparable. The question is how to charge something like a "photo flash" and throw it out in 3 seconds. This is the problem.

You are a little confused. Multiply even then the energy of AK bullets by 3600 .. But actually .. the bullet has kinetic energy, and the potential of the accumulator.

[dauria]

Multiply even then the energy of AK bullets by 3600

What for? A watt multiplied by a second is equal to the joule. (A * B * sec) is a battery. Kg * M sq: sec sq is also a joule.this is a bullet (Em ve square in half)
"We have everything exactly - 400 drops of valerian."

He simply showed in numbers that the energy storage gunpowder (taking into account the efficiency of conversion from heat of combustion into mechanical heat) is comparable to a lithium battery. I don’t know the machine, but it’s already possible to build a hunting double-barrel.

[dvina71]

Quote: dauria

What for?

Then, gunpowder creates an impulse that accelerates the bullet in the barrel. Chem cannot create a pulse accumulator, capacitors are required for this.
HERE and calculate how much energy the conders must accumulate in order to disperse a bullet weighing 6 gig to 800 m / s and what kind of IP is needed for this .. And this is definitely not a cumulative battery.

[Nikolay K]

Imagine both a capacitor and a battery, this is energy storage. Just the first can give energy quickly, and the second can be stored for a long time.
Another hint: you can store energy in the battery, and already charge the capacitor with it. Dauria popularly explains that the energy of a modern compact battery is enough for a few shots from a railgun. Now the problem is just to create compact and inexpensive supercapacitors.

Well then, you count .. how many shots are enough for the laptop ..
There is nothing complicated about it .. I assure you. but tired of idle talk.

[Nikolay K]

That's right. And then they write in the article:
"However, it is not yet clear how scientists will be able to solve the problem of powering this weapon - after all, even one shot from such a gun requires a huge amount of electricity," the newspaper notes.
As if the laws of physics do not apply to the railgun. The problem is not the huge cost of electricity, but the fact that energy needs to be issued in a very short period of time, because the rails are short and the projectile accelerates very quickly. I just can’t understand why they won’t make the rails spiral or don’t ring them at all, then the problem with supercapacitors would be much easier to solve.

[ARES623]

A little more than a hundred years ago, airplanes were just a new dangerous circus attraction without practical use. No need to say what it is today. I think, over time, the railgun will also be brought to an acceptable level from the point of view of practical application. The main thing is not to oversleep the "low start", as with cybernetics.

[good7]

The benefit is obvious, but how to power this shushpanzer?

[andranick]

Quote: good7

But how to power this shushpanzer?

Everything is solvable. Of course, you can’t put it on a tank or plane, but nevertheless it is possible. It will shoot until the barrel melts. The main thing is defined in terms of: Portable is what? Wearable, carried? towed? ;)

I remembered:

[askort154]

andranick .... portable what is it? Wearable, carried? towed? ;)

Portable wearable, for special forces only. A fighter with him, and after a fighter an armored car with batteries and capacitors.

[andranick]

only hardcore!
although here many were interested about the mule, they say like nafig he is so needed. and here
here it is, here it’s like ... BATTERIES TO DRAG THE RAILSTRON!

[Neko75]

They don’t talk about secret things. And if they started talking openly, then yes ... they get out financing, even if the project is obviously dead end.

[PPD]

And how many articles about Newlinkor with a railgun will be written. About infantry kits of the future.

[Mountain shooter]

Another nonsense. Railgun on an armored personnel carrier? With a power plant on a trailer? In general, something from "Star Wars". Hollywood weapons.

[Egen]

until there are compact energy custodians - capacitors or xs what else, all this is good but stupid. And such batteries will appear more likely where demand is greater - on cars. Then we’ll see)

[Just felix]

the same thing happened with lasers, what they feed, what they feed, they powered. Now the problem is how to cool, and there is no doubt that the method will work out.

[Rosty]

The issue is nutrition. But, say, for cannon defense systems for ships with a nuclear power plant this is not a problem, and there this idea would be very popular.

[evge-malyshev]

Apparently, someone dreamed of the name "weapon" in a feverish or narcotic delirium.

[MolGro]

But what about a non-portable railgun? He’s already all)
If you can’t do big, we’ll do small)
I remember the movie!

[Mainbeam]

And as for me, so promising a contraption for ships. A nuclear reactor (or two) solves the issue of power equipment. A dozen parallel condors with parallel charging and with sequential discharge - solve the issue of rate of fire. Magazine supply of shells - the same to the rate of fire.



No powder charges are needed - weight reduction and simplification of the design of the automatic loader. The rate of fire is not as critical for heating a gun as when using gunpowder. And at such a projectile speed (the first space one) the usual feathered blank is enough to destroy the enemy with kinetic energy.

It’s good to be a battleship - one tower was broken, four remained :-)

[NOTaFED]

What are they shooting with? And at what distance? Great speed, friction against the air ... Will not reach, burn ...

[voyaka uh]

Put on Zumvolt. He has a crazy power supply - 78 MW.
Floating power plant. Especially for the bells and whistles of the future: railguns and lasers.

[dvina71]

Quote: voyaka uh

Put on Zumvolt. He has a crazy power supply - 78 MW.

This power supply will not help him much. We need supercapacitors, because a shot needs a pulsed discharge of very high power. This is the first problem. The second is barrel heating. the third is very fast, plasma is no joke to you.
So zoom with conventional trunks is like.

[Vadim237]

A barrel can generally be made of tungsten — all problems can be solved — tests of this weapon on a ship will be soon.

[O. Bender]

Godikov, after eleven years, we recall how we mocked. To have something in the future, we must not sleep in the shafts of the present. And about the cut .... so let them saw, thank God not our budget.

[tchoni]

Judging by the caliber, the device is intended for arming armored vehicles and for fighting it. In this case, the problem of powering the device is removed because the developer has at his disposal a motor of several hundred horses. And the energy of a fiftieth caliber bullet dispersed to 3-6 km per second, in theory, should be enough to deal with serious armor.

[Chulman]

Will shoot turn off the electricity!

First, you need to decide what to make such a "blank." far from the original.

[Mainbeam]

This is understandable :-) The whole joke is that when the first publications about the railgun went, it was thought that they built garbage !? What is it for? Who the fuck do you need this for? But the idea itself is cool - to throw nuclei on the enemy side with an electric impulse.

And about hypersound and do not need to steam. Remember when the first reports of supersonic torpedoes went? So after all, no one believed that such a thing was possible. So here too - how to control a hypersonic aircraft is not clear due to the plasma generated around the vehicle. And this "shell" does not have a control issue. Launched - and forgotten. Or, as with tracer fuses, they will only be placed in the front to form the same plasma.

This is a technical issue. And the railgun is the weapon of the future with the prospect of a breakthrough in many related fields. It’s like the invention of aerobic submarine installations - a step forward. Definitely.

[Santjaga_Garka]

I can’t say for sure, but most likely our scientists will make the Rail Gun on the ship more advanced in many respects, as was the case with the multi-barrel air gun, I recently read an article here *)
