Bryansk specialists have developed a method for making tank armor from wire

80

The team of the Bryansk State Technical University (BSTU) has developed a manufacturing method tank wire armor.


This information was received by the agency RIA News from the Foundation for Advanced Study (FPI).

They said that using additive technologies, armor for military equipment is grown by fusing wire, which is then subjected to wave deformation. This technology was developed jointly by BSTU scientists and FPI specialists.

This technique has already become interested in a number of enterprises of the Russian defense industry engaged in the production of armored vehicles. The developers have already given them the results of their work.

Studies have shown that the weight of armor grown by the additive method is 15-20 percent lower than that of armor made using traditional rolling technology. In addition, when using the innovative methodology, material savings and higher strength of the finished product were noted.

As a result, a lighter and more durable armor is obtained, and the cost of its production is much lower than when using standard manufacturing technology.

The development of Russian scientists is extremely relevant for the military, since recently the world defense industry has created powerful ammunition with increased armor penetration.

    good Well done!
    The winding of outer casings on the barrels of guns, more durable than rings, was known.
    But the complexity ....... request But still, we are the best.

      If such armor is on the T-90, so it will fly. good

        He already flies repeat it is better to use this technology where the power is lower, where the specific gravity plays a significant role.

          Can I also use aluminum wire? if so, then both Armata and Tu 57 and PAK DA I MIG 41 are much easier, more maneuverable, more economical and therefore more affordable.
          Then just load the modernization factories to the full and sell the "old" equipment and all the newest for the release money.
          By this, everyone has enough work.

        hi And over the hill they like to shout about our economy torn to shreds, obsolete technologies of the military-industrial complex, etc. And then, in both, take a bite. In general, of course, it is interesting how it is GREATED armor made of wire, I can not even imagine.

          The fact is that one does not exclude the other. The economy is really in a complete and hopeless ass, but we continue to play toys. Moreover, all these tanks at exhibitions and in presentations, all this armor made of wire - have nothing to do with the real defense of the country. This is color music, and nothing more.

        And if on T80), but in fact, reducing the mass by even 5 percent is already a revolution, and then there is also an improvement in the characteristics of armor. With less weight.

      The winding of outer casings on the barrels of guns was known,


      Steel wire was also wound onto aluminum supercharged fuel tanks. And in ancient times, they made bundles of wire of different varieties - hard, fragile and soft. Loosened into a layer and received a "composite" sword.

      I think two samples are compared for breaking load. Accordingly, in the case indicated in the article, the weight of the sample (thickness, area, section, etc.) will be less, and the resistance is the same

      additive technologies (layer-by-layer building) are ancient, but began to be used (discovered) in England in the mid-1980s.

          Has it touched? Did Brezhnev hurt Stalin? Obviously he was, but this does not negate the fact that Brezhnev was generally successful as a ruler. This is normal, the people are the same, the people are the same.

      The new is the well-forgotten old. At one time, using a similar technology, the shells of the main caliber of battleships were made.
      (The barrel consisted of a monoblock shell and a liner, i.e. an insert)

        Why be smart where you do not understand at all?
        First, a candy bar does not have a liner, it is a candy bar. Secondly, according to additive technologies, no one has ever made or does any "barrel shells".
        The article was written by illiterate journalists who did not understand the role of the "wire" in this process.

          Listen, senior warrant officer, learn to read, then you will puff out your cheeks.
          I repeat, read carefully: "The barrel consisted of a monoblock shell and a liner, ie an insert"
          You meant the monoblock barrel, cast as one piece, and I wrote about the shell. You will be surprised, but they are not the same.
          For heavy implements, a barrel structure made of two (or more) pipes, with or without liner, is possible.
          And the structure of the shell (casing) can be both bonded and monoblock.

              Wow, for some reason I switched to "you", but started with "poking", so the answer was in the same language. I see no reason to throw beads in front of the "pumpers".
              Now to the point. You, it seems, did not lean against the artillery in any way. Before teaching someone, look at something on the topic in any textbook to understand what it is about.
              I repeat, only the barrel shell (casing) was made of wire and the barrel had a liner.
              Moreover, the wire sheath was made in a monoblock, i.e. from a single pipe, rather than bonded, which is made from two or more pipes.

                      I'm too lazy for that. And this sketch was laid out much earlier than the current discussion.
                      In general, the term "monoblock" is applicable to many designs, not just barrels.
                      In this story, I am more interested in the unknown term "Ilenism", I am simply burning with impatience to learn its innermost meaning, but dictionaries are silent ...

    The article on VO looks more like an attempt to find a foreign buyer for the know-how of Bryansk experimenters. Everything is for sale. Not a word about the secrecy of new directions and developments.
    Loot wins EVERYTHING!
    Either the screws will be sold from a decommissioned ship, or new promising developments.
    Disgrace ......

      dada, everything is gone ... three imported tape recorders ...
      what have the screws from the ship? for once, you should not whine, but be happy for our developers

                    Forged, and the quality was good, while they were actually made piece by piece at fabulous prices using multi-layer technology.
                    but then, when from the 14th century a much larger amount of inexpensive weapons was required, the quality of the metal dropped dramatically, and in the Momoyama period - the 16th century - imported European metal was used for swords.

          The innovation is most likely in the technique itself, the principle has long been known. It is also necessary to develop equipment, select material, conduct test tests. An ordinary manufacturer will not bother with something new, with a streamlined technological process.

        You didn't bake a lot on the printer - it won't give additional strength and impact strength to the armor, since this requires a hardening process.

    the global defense industry has created powerful ammunition with increased armor penetration

    The "World Defense Industry" manufactured "Bayraktars", which perfectly kill armored vehicles, hitting them from the top projection, incl. now, it seems, you will have to direct the "Curtains" upwards and build up the upper armor.

    No, this is not a printer.
    The layers are built up not in pieces, but with wire, i.e. whole linear structure. The splicing wire can be stretched, i.e. there will be strong internal tension.

    It's like imagining a basketball net, how it will behave when a ball hits it,
    If it is taut or simply suspended by one side.
    Of course oversimplified, but so an example for clarity.

    In addition, 3D printers do not print with any material; special alloys are used for armor.

    Studies have shown that the weight of armor grown by the additive method is 15-20 percent lower than that of armor made using traditional rolling technology.

    what
    And in "Rossiyskaya Gazeta" yesterday it was just like that:
    Protected by a new method 15-30 percent lighter homogeneous, and its strength is higher.

    repeat Rumor has it that articles were sprinkled.?.
    In general, they made a note, and then we still have to figure it out ...

      It can become lighter because of the voids between the wires. Which can be made of steel with different strength. And fill the voids with some kind of binder. You never know there are high-strength polymers ... well, or glasses. Soak such a block - it will be easier for anyone.

    As a result, a lighter and more durable armor is obtained, and the cost of its production is much lower than when using standard manufacturing technology.

    Doubtful.
    In a piece production (pilot) - maybe cheaper.
    And when switching to a series - and not cheap and not fast.
    Fairy tales about "cheap" additive technologies, distributed by sellers of 3D printers.
    One case takes weeks to form - how much equipment should work in parallel to do at least a small batch every month?

    Bryansk State Technical University

    People who are the last to think about the cost - considering the standards for outdated reference books of the USSR and taking the coefficients almost from the ceiling, hardly any of them spend the day and night in the production of armored steel. It is common practice to first "be able" and then adjust the cost calculations with tricky numbers.
    When the production changeover begins, there will be no demand from the developer's calculations, and there the numbers may fly away by orders of magnitude - a tricky kitchen, because the developer is not responsible for the final product - the maximum will be replaced by the GC.

    which is then subjected to wave deformation

    And how will "wave deformation" be cheaper than rolling armor steel on a roll mill?

    All this must be checked and weighed the entire stage from equipping with a new machine park. changeover of production.
    Most likely, the developer did not take into account the production cost of the corresponding material (wire to form an armored body), for which production will have to be created from scratch).

    Well, they did. In theory. It is also necessary to develop and introduce production technology and create armored vehicles with such armor, confirm the characteristics, begin deliveries of our army and for export. Instead, an advertising campaign for the "achievements" of BSTU is being carried out.
    I suppose that in fact we are talking about the "scientific work" of a third-year student, in which the materials of the candidate's dissertation (possibly even never defended) of an associate professor of one of the departments are "implemented". The real purpose of the "scientific work" is to receive a grant of 500 sput. within the framework of the project of the Ministry of Education "Clever men and clever men" (Hihi-s).

      Armored screens - mounted can already be made by this method, and most likely these guys already have an economic calculation, how much is one ton of rolled armor steel and one ton of theirs made using layer-by-layer deposition sintering and hardening by wave deformation.

    Well, this property has been known for a long time. The smaller the diameter of the wire or the thickness of the sheet, the greater the tensile strength of the material from which they are made. Fewer defects. In presses, this is used - instead of monolithic rods, a steel tape is wound. But for armor - this is the first time!
