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.


In the United States began to develop a portable railgun


“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. ”

            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.

              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.

                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 .

        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.

      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.

        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.

          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.

              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)

              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.

                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.

                  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.

            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.

    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.

    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 :-)

      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.

    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.

      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.
