\"41dfff6f153a8de7c7ff0cc9fbbe9ada\"<\/a>The issue of individual protection serviceman was one of the key at the last exhibition “Army 2016”. Its development there provided OJSC “NII Stali”, part of the Concern “Tractor plants”. About that, what the civilian population broneodeyalo, new materials and liquid armor to heavy armor complex “Designer” and test to mine resistance in an interview to “Star” television said the deputy general director of JSC “Research Institute of Steel” Evgeny Chistyakov.<\/p>\n

One of the latest developments, “NII Stali” – broneodeyalo. Tell, for whom it was created?<\/p>\n

It is a product that can now be used in hot spots where civilians suffer. They have no protection there, so “SRI Steel” has developed several products to help these people. It is simple and cheap to manufacture, does not require any know-how, but nonetheless provides an excellent protection against fragments, including from the secondary. Broneodeyala have a decent enough level of protection. About 80% of all the fragments, which are formed by the explosion of mines and shells, it stops.
\nAnother interesting development – a cover of aramid ballistic materials. Putting it on the usual construction helmet, you turn it into an army. If a normal army helmet provides Ballistic protection at the level of 650-670 m \/ s, this construction helmet will have a protection level of 550 m \/ s. This is enough to protect yourself from debris. It can come in handy at work. Should such a case much less helmets, and they may well provide themselves with the company, working in hot spots.<\/p>\n

What do you think, in what direction will develop materials and human protection?<\/p>\n

Today there are two types of materials that can hardly be replaced with something. This ceramics and high molecular weight polyethylene, which comes to replace the foreign Kevlar, and other domestic Rusar aramid fabrics. Now it is cheaper than Kevlar, and its production is established in many countries. Moreover, it grows exponentially. In Russia, only polyethylene is imported and set up production here only promise.<\/p>\n

How does a high molecular weight polyethylene?<\/p>\n

In a conventional plastic bag molecules are arranged randomly, so the relationship between them is weak. In the high molecular weight polyethylene molecules are arranged in a chain, which is very hard to break. Thus, a fiber which is not inferior in strength aramid.
\nWhat are its advantages over the aramid fabrics?<\/p>\n

Firstly, it is not afraid of water, in contrast to aramid fabrics which when wet to lose 40% of their characteristics. Therefore, they require a hydrophobic impregnation agents. Second, the polyethylene is easily compressed, and it can be made of rigid and semi-rigid plates, which are lighter than water and will float. As regards the protection level, the resistance characteristics of polyethylene and approximately the same weight as that of the aramid fabrics. For example, there is an interesting feature: how high you can raise the thread based on its own weight. If you take an equal weight of steel wire rope and a rope made of polyethylene, in the first case, you will be able to raise it to 10 km, while the second – 200 km.
\nThe second material, which has no analogues today – it’s ceramics. If polyethylene – a protection against fragments and pistol bullets, the ceramic – a protection against armor-piercing bullets.<\/p>\n

Modern body armor still cover only the vital organs. Are there any currently working on the protection of limbs?<\/p>\n

Of course, such works are carried out. When a man gets shot in the leg or arm, it still fails. This is not a fighter: it needs to be treated, transported. Therefore, the dream of all the military – to provide maximum protection. Unfortunately, modern materials do not meet the small arms whose power increases exponentially. A protection area decreases. Previously, plates were 20-40 square decimeters, and now the total area of \u200b\u200b8 square decimeter. Who among the experts, there are disputes about what is important now or to increase protection against fragments and pistol bullets, or still do a small square plate and assume that the person is protected by armor-piercing bullets. The dispute is over, it is difficult to say. At the same time abroad, the issue has long been resolved. They have basic protection Fragment, and if necessary, a fighter puts a heavier set of protection.<\/p>\n

It should be noted that we have the same protection complex, designed by “Research Institute of Steel” – a bronekomplekt “Designer”, which is a completely new development. This is a heavy suit – it weighs 20 kilograms. It is clear that the fighter in him will not be able to make a forced march of 20 kilometers, but if you want to break into the room, to hold the assault operation, it provides the necessary level of protection in all fully torso, neck and extremities. It turns out the man-tank.
\nThe developers have tried to make the most ergonomic suit. Usually, a fighter can not be set in a heavy armor maneuver quickly, can not sit comfortably. However, the complete “Design”, we have tried to reconcile the irreconcilable – for maximum mobility, ergonomics, to redistribute the weight from the shoulders to the maximum times that 30 percent reduces the apparent mass, and finally, as much as possible to protect the limbs and joints.<\/p>\n

Of course, you do not have to wear this kit on yourself all day. It is used mainly for special operations that occur transiently. Furthermore, it should be noted modular design. At unfastened vest shoulders, side modules and get the usual standard vest.<\/p>\n

What other developments in the area of \u200b\u200ban individual defense now under way in Russia and in the world?<\/p>\n

Who came to the forefront exoskeletons, because there is a crisis of materials. In addition to ceramics and polyethylene nothing else in sight. Currently there are no such materials, which could make a revolution. That revolution made armored vehicles, two systems: the dynamic protection and active protection. Perhaps such a system in the future there will be also a fighter, especially since there is now such ideas as bullet tuck her to try to destroy as much as possible. This direction is engaged in Russian and Belarusian companies. Abroad engaged liquid armor. Its main feature – a hardening of the shear. The vest is a special suspension and in contact with the bullet, it becomes hard and behaves like a rigid structure. We are also engaged in liquid armor and came to the conclusion that it saves you from damaging elements, flying at speeds up to 350 m \/ s. Above it simply does not have time to work. And abroad serious progress in this matter.<\/p>\n

What tests do you spend in the development of your products?<\/p>\n

One of the interesting test – this test of mine resistance. What will happen to a person when blasting machines? This question was always interested in professionals. Abroad for a long time in this area of \u200b\u200bwork underway now we started working with us. To this end, we made a stand, equipped with special sensors. There you can put dummy undermine in the real world and see how critical is the design, which is designed designers. It is noteworthy that one of the key roles played by the seat here.<\/p>\n

That is, it is something like a car crash test?<\/p>\n

Absolutely. Only if the car is low-speed test dummy here undermines real ammunition. There are high-speed cameras that record the time of the explosion, as the flying debris and how they affect the dummy.<\/p>\n
