The technology used in the protective equipment "Sotnik" was appreciated in the Greek press

73

Foreign military experts assess reports that new equipment for the military is being developed in Russia. We are talking about the "Sotnik" outfit, which in a number of parameters should surpass the already operated versions of the "Ratnik" military outfit sets.


In the Greek press, special attention is drawn to the fact that the new generation of equipment being developed in Russia in terms of its protective blocks will be made from a supermolecular (ultramolecular) fiber based on polyethylene. This is a bulletproof vest, which is significantly lighter than existing counterparts, and the new material will protect the fighter from shrapnel with high dynamics - up to 670 m / s.

Greek experts note that at such a speed, the mechanical interaction of the fragment, even if it does not penetrate the body armor, can lead to fatal damage to the internal organs of a person. But it adds: the development is valuable because the design of the bulletproof vest of the "Sotnik" set has a high amortization component - the impact force of the fragment is distributed evenly over the entire surface of the protective equipment, significantly reducing the impact on a specific area.

Pentapostagma edition:

The Sotnik Russian protection kit is unique in the technology it implements. When a bullet hits a polyethylene-based material, it partially transfers its heat to this material. In this case, ultramolecular polyethylene at the site of the bullet hit in a split second partially melts, distributing the impulse of the ammunition over the entire area of ​​such a bulletproof vest. The bullet is, as it were, captured by the special structure of the material, losing its lethal characteristics.

Earlier it was reported that the tests of "Sotnik" should be completed in 2023.

      I would also. That's amazing. Ordinary polyethylene. Only well "crosslinked" molecules - and the fiber becomes much stronger than steel ...

      there would also be neck mounts with restraints for the helmet, so that a hit in the head would not break the neck, then there would be no price at all.

        Not a bad idea, but how will this affect the mobility of the head, if this theory is embodied in general gorgeous. But I can't believe it, the neck is the area where they least get.

          full mobility is not yet precisely provided. but in the main areas the level of freedom will be sufficient, that is, at least during the battle, it did not limit the turn of the head, but so far one cannot count on head gymnastics in such a helmet.
          Still, a protective collar for sentries so that they would not slash and choke on the throat (although it may no longer be relevant, the times are not the same that would be removed with a knife).

          here a fixed helmet is more suitable, where a fighter can turn his head inside the capsule, or a fixed part of the helmet in combination with a rotary one, but this is already an exoskeleton.

            you can make a couple of degrees of freedom with small restrictions and this will not be too complex a design. there the only thing is that the materials will be light and therefore a strong impulse is unlikely to withstand. but it will keep the fragments and bullets at the end. you can hold a bullet, but there the weight will be several pounds from above.

            But it will require training so that you can turn your body around at the reflex level. Particularly important is the moment _ in cramped conditions: lying down, for example, will need to raise the shoulder to turn.

                  all others follow the leftover principle, this is understandable - the economy should be economical. As it was in our unit - everyone was taught to ride all the equipment that was in the unit (armored personnel carrier, BMP-1/2/3, IMR, MT-LB) and do not care that because of your height your head sticks out of the mechanic drive hatch, everyone who had category B was forced to pass the CDE, those who did not have B was forced to study and pass, taught to shoot from everything that was - because a soldier of the Engineering Troops should be universal, as in theory everyone else in our army.

    The mount should be such that when hit, the helmet flew off the head and does not transfer the energy of the bullet to the neck.

      this is if the hit will be in the upper part of the helmet, if it does not fall into the ear without the head with it.
      there are only additional fasteners that will transfer all the energy to the body.
      that is, limiters of rotation and tilt of the head attached to the armored suit.

            but a collapsible cup-like throat fixer can even be on light armor and weighs quite a bit
            All this has already been invented a long time ago. The truth is at a different technological level. And the design is honed to millimeters and trifles:
            The first option is more complicated. Full articulation of the gorget with the helmet. There are no vulnerable zones. Full mobility.

            Option two is simpler. Gorget is worn separately. On top of it, the cervical cover plates, attached to the helmet, are lowered. There is a vulnerable zone - an upward strike along the body can go to the head. The mobility is also complete.

              I have an idea about a collar on the principle of a folding cup, when the blow to the head goes to the rings around the neck and from them goes to the armor.

                  those gorgets that I saw and here are given to protect the throat from blows, and not the neck from breakage, in general I understand you, but I'm a little about a different design.

                    By the way, the boas did protect the neck from breaking when it was thrown back. After all, they helped themselves to survive the ramming blow with a spear in the face. But there it was solved in a complex way. Not only by the design of the neck joints, which allowed the head to be tilted, but not to critical angles. After that, the design chose a free stroke and the blow went into the body. But also the shape of the entire front view for maximum ricochet of the spear. It would seem that it was invented more than five hundred years ago, without knowledge of any strength of materials and calculations of diagrams. And the design is perfect.
                    There were also more rigid versions - bevors and gothic-style gorgets. Which were attached to the front of the cuirass. But there, mobility was already sacrificed.

    This can be solved with the help of hydraulic shock absorbers that will be attached through a hinge to the helmet and the other end to the back of the armor. so the energy of the impact of fragments and bullets will not be received by the head, but by the helmet itself, the forward impulse to the extinguishing mechanism bypassing the cervical spine.

      This can be solved by using hydraulic shock absorbers that will be attached through a pivot to the helmet and the other end to the back of the armor.
      It works. But it completely limits the mobility of the neck. For example, looking forward from a prone position will be impossible.
      Unless only use non-Newtonian fluids in the design. To allow such a hydraulic shock absorber to pass head turns without problems. And upon impact, it became a monolith.

            I about it
            However, the most eye-popping claim about this equipment is that its armor protection will be able to stop a 12,7mm bullet with regular plastic. Here is what Task & Purpose writes about this:
            "The fourth-generation Sotnik armor will consist of light polymer fiber and armor plates, designed to withstand a direct hit from a 12.7 mm bullet from a Browning machine gun."
            Polymer fiber is of course plastic. Like any plastic, it is found almost everywhere. You can be sure that right now, any of us is a couple of meters from an object made of plastic.
            Polyethylene polymer armor is real, and exploits a common disadvantage of plastic: it melts. When a red-hot bullet hits the armor, it melts the polyethylene. The molten polymer sticks to the bullet and slows it down. If enough plastic gets in the way, the bullet will stop completely.
            Russian polyethylene armor is called "Superfread," and Russian state media claim that this material is lighter than Israeli and American body armor, but provides better protection.

    The Greek press often began to talk about Russian weapons.

      If they start praising in the USA, then you need to be on the lookout .. And the Greek, Chinese and "Mordovian Bulletin" .. It's just a cover))))

    Earlier it was reported that the tests of "Sotnik" should be completed in 2023.


    In two years, new materials and technologies may appear, which will make it possible to improve it ...

    The bullet is, as it were, captured by the special structure of the material, losing its lethal characteristics.

    Quite good characteristics, of course, but it's better not to fall under the bullets of Kalash or DShK .. You can turn into minced meat, although there will be no holes .. hi

      From the Kalash, especially the five, from a certain distance and the previous armor normally holds. But at the expense of the DShK, you really burned it. laughing
      Two or three bullets from this machine gun, hitting a person, simply tear him into several pieces. And then no armor will save. It hits a limb, tears off a limb, in the head - the head, in the body, crumples the fuck into a crap (the guts will come out of the ass).
      A classmate, in 79-81 he rode to Herat, Kandahar and other settlements of the glorious republic of Afghanistan, more than once he was under fire. Described in sufficient detail what the heavy machine gun does to the personnel. I myself also had a chance to shoot from it, at the Ladoga air defense range, at towed cones and ground targets. A real gun. The earth trembles when you hit it from a tripod buried and hung with duffel bags with sand for stability. A standard concrete block, almost half a meter thick, is crushed into dust three or four hits. A wall of three silicate bricks is pierced without even noticing (red is a little more difficult, but also not a question). And you are here about the armor melon casting. laughing

        Alas so .. Therefore, all these armors are needed of course, but they cannot save from serious weapons .. Tactics and intuition can also save the ability to merge with the terrain .. This is the only way to survive and still dig in without being lazy competently and posting posts in the right direction. all the same, the ammunition "Sotnik-Ratnik" is good, agree? And then we always saved on soldiers .. Well, God forbid it will reach the Army, of course not everyone will get it, but I hope that the advanced shock will definitely come .. We need to take care of our soldiers, few of them are real left with fighting spirit from our ancestors. hi

          What should I agree with? With obvious stupidity or obvious banality?
          It is clear that the armor is better than without it, as well as the fact that it does not save from a direct fire from a tank gun. laughing
          No offense and nothing personal. hi

    The only thing left to do is to ask the Burundian press

      With the widespread distribution of armors, we should expect an even wider distribution of bullets with a tungsten carbide core, for reference, in first place in the world, China, produces 70000 tons of tungsten, Russia is in fourth place with only 1 tons, if the cores are guessed to be not round in cross section, but for example triangular, then when the polyethylene armor breaks through, the effect of cutting them will be added to the rupture of high-modulus fibers,

        In this case, the mass of the core will decrease, which means its kinetic energy and armor penetration.

          For example, in the m 5.45 7N24 cartridge, the bullet weighs 4.1 g, the weight of the core made of an alloy of cobalt and tungsten is 2.1 g, in other cartridges the bullets usually weigh less than 3.8 g, but there is also a cartridge 5,45 PRS, with no ricochet bullet, its copper shell is completely filled lead bullet weight 3.85g (weight separately of lead and copper is unknown), you can estimate how much it will weigh if tungsten is placed in the lead in the shell
          lead 11.34 g / cm3
          tungsten 19.25 g / cm3
          that is, tungsten is 1.7 times heavier than lead
          if we neglect the weight of the copper sheath, then such a bullet will be slightly less than 6.5g, that is, for a 5.45x39 cartridge, it is possible to create a pool weighing close to 6g without changing its dimensions., of course, its initial velocity will be slightly less, but not essential.
