Composite materials will be widely used in the construction of 5-generation submarines

Russian submarines of the 5 generation will be built from new composite materials that will noticeably reduce their visibility, reports RIA News report of Valery Polovinkin, advisor to the general director of the Krylovsky State Research Center enterprise.




“We are talking about new multi-layer composite materials. Their structure and composition reduces the reflected sonar signals from a submarine, prevents the spread of vibration from working mechanisms, and so on, ”said Polovinkin.

According to the advisor, “the enemy simply will not receive the signal reflected from the submarine of the required level, since the composite material has a high internal loss factor, or sound absorption, can change properties when vibration occurs, completely preventing the propagation of vibrational energy.”

“The use of such composites in the design of submarines allows not only to reduce weight and increase reliability, but also to reduce operating costs, since composites do not require painting and do not corrode. In addition, structures of this type can be manufactured in one technological process, which reduces the laboriousness of manufacturing body parts or mechanism assemblies at 30 – 40% ”, - he explained.

Some products created on the basis of composites, already undergo bench tests. “The first adaptive composite propeller can be submitted to full-scale tests already in the 2018 year,” said Polovinkin.

“This is one of the most promising works of our institute. This direction ensures a reduction in the level of vibration of the blades and an increase in the efficiency of the screws. Due to various effects, the acoustic field of the ship will be improved. By creating a new material structure, the blade will adapt to the flow around the hydrodynamic flow, depending on the speed, ”he said.

    In fact, they have been used there for a long time. Take at least a solid outer rubber coating of the hull of a submarine. (that's why they are black).
    In general, the transition to composites is a general trend in military affairs. Our submarines always did well. I wish good luck to our engineers, and to the factories building up the necessary capacities good

      I wonder if there are currently materials and technologies that allow WHOLE "glue" the solid hull of a class submarine ... for example, "missile carrier"?

      Deliberately emphasized the class of the ship, since the small class submarines made of "plastic" have existed for a long time.

            In "autoclaves" or, for example, in "vacuum chambers", SECTIONS of cases could be "baked", right?
            Indeed, just like that, now welding of submarine cases from sections with the parallel installation of large-modular equipment is being performed.

            With the subsequent connection "together". Nobody is pushing on "pasting" a solid "monocoque".

            Although, perhaps, the engineers are bold and such.

              And more is not necessary. An AM machine (3D printer) does not have to be larger than the manufactured product.
              But the principles of design and production will have to fundamentally change. Even the economic model of production will have to be changed. And simple things will happen:
              1. The share of intellectual labor will become overwhelming (above 90%), and only highly qualified engineers will be involved in production;
              2. The complexity of product design will be increased significantly, and it will become easier to make individual solutions "for the task".
              3. It quickly becomes clear that not all engineers are capable of creating constantly new products under given conditions, but only engineers with creative abilities.
              And then a childishly simple question: WHERE WILL THE "Tvortsy" ENGINEERS COME FROM AT THIS PRODUCTION AND WHY WILL THEY BE INTERESTED IN WORKING AT THIS PRODUCTION ???
              The simple question is true?

          While the cousin was alive, the designer of the submarine (corps) spoke about the double and triple cases with an intermediate power frame, the model models from the composite were already glued. And my grandfather has not been there for 14 years. Already then they thought about this.

            You are very wrong. You are wrong because prices are artificially kept high by material manufacturers to justify "development costs". In fact, often these are not even their developments, but patents are the result of the work of lawyers, and not the result of research.
            As for the materials produced in Russia, this is not their development at all, but the legacy of Soviet research institutes.

        No, it doesn't exist. It is impossible to "glue" the body, you can make coatings and separate monolithic parts. Or non-compressive structures inside a robust housing.
        There are separate technologies for "baked" materials, polyethylene, polycarbonate, I don’t know if they can make cases from them.

      Source: Husky submarines will be armed with Zircon hypersonic missiles

      The newest Russian multipurpose nuclear submarines (nuclear submarines) of the fifth generation of the "Husky" class will be armed with hypersonic cruise missiles "Zircon", a high-ranking official of the military-industrial complex (MIC) told RIA Novosti on Thursday.

      "The Husky nuclear submarine project is currently under development at the Malakhit design bureau. These submarines will be armed with Zircon hypersonic cruise missiles, the tests of which have already begun," the agency's source said.

      "Actually, they have been used there for a long time." Perhaps you have no idea - HOW long ago .... And, in general, the Germans were the "pioneers" here: "Since the end of 1944, the lining of the hulls of the XXIII series boats with the Alberich antihydrolocation coating was started, which received its name in honor of the owner of the hat. Invisibles from the legend of the Nibelungs. The coating consisted of rubber sheets 4 mm thick with internal air cavities (horns) and provided a decrease in the level of the reflected echo. By the beginning of 1944, the specialists of the IG Farbenindustrie concern had solved the technological problems of coating. " : //putnikost.gorod.tomsk.ru/index-1276526239.php It was this coating that formed the basis for the use of analogs, naturally modified "in the submarine of the USSR.
      And the fact that "in general" composites are in trend is absolutely true, "... and so on," Polovinkin said. " There is a natural desire - to clarify what is actually meant by "... and so on."

      "The Zircon hypersonic missiles are already in metal, and their tests have begun from the ground launch complex," the agency's source said.

      According to him, the speed of the rocket should be about 5-6 Mach (Mach number means the speed of sound).

      The Zircon missiles will be installed on the fifth generation Husky nuclear submarines. The Malakhit design bureau is developing the latest Russian multipurpose nuclear submarines, the source said.

          In the exposition of the Krylovsky Center, full-scale samples of products made of composite materials were presented, which can be widely used not only in shipbuilding, but also in structural mechanics, and various fields of mechanical engineering. Among them:
          outer sheathing of the superstructure of the vessel in the form of a three-layer panel manufactured by the method of vacuum injection in one technological process;
          vibration isolating coupling for use in ship propulsion complexes, pump and compressor stations, power generating sets;
          a fragment of the panel for use as the walls of superstructures and deckhouses made by vacuum injection in one process;
          deck overlapping of a three-layer flooring with homogeneous aggregate for the construction of ship decks and platforms, decking of piers and mooring walls, bridges, floors of buildings and structures.

          vibration-isolating coupling is an interesting product; it may be relevant for sub-bus radar helicopters.

        And I see a huge jerk! In addition to reducing the cost of the propulsion (screw) itself, the use of composites promises another important plus. This is a wonderful material that resists cavitation very well! And cavitation is a process that destroys any screw from any metal (or alloy). Moreover, these cavitation-resistant alloys are very expensive. Today, more and more often in production, impellers of pumps are not made of bronze / brass, but plastic. Cheap and cheerful! With less maintainability (it doesn’t exist here at all), maintenance is simplified: the pump has broken down - replacement with a new one (since the cost of the pump is low). Advantages are undoubted: durability and low cost. I have not yet met large propulsion devices from composites, so there is a real breakthrough if everything works out by 2018.

          Cavitation processes do not destroy the entire surface of the outflow, but only regularly determined areas. Therefore, an increase in the velocity and pressure of the outflow only increases the destructive effect both in the depth of the surface of the blade and in area. But it is important to understand. which cavitates not the entire volume of the flow in the areas of destruction, but only its small part. Therefore, the new and proposed technology allows not only to increase the volume of cavitating flow, but also the speed of such a newly incoming flow under cavitation. The question, after all, is that the cavitation zone is simply displayed outside the surface and is located in a separate part, which only contacts the blades on a very narrow edge. In this case, another part of the rotating flow with maximum speed breaks this cavitating flow. Everyone is struggling with cavitation, but it can and should be used. In this case, you need to understand what cavitation is and what is its derivative. And this is a separate issue, which ultimately leads us to the fact that hydrocarbon fuel becomes useless.

            The beginning of the comment is interesting, since I know very well what cavitation is and where it takes place to be. But the ending is just nonsense! How can cavitation be attracted to hydrocarbon fuel? You want to say that, for example, a screw on a solar powered yacht does not cavitate? More in detail from now on?
            I believe that cavitation does not have a positive result, if it takes place to be on the mover of the submarine. Since when the vapor bubbles soak, energy is released. So, the corresponding noise background is added, which allows you to determine the location of the submarine.

              if I answer you completely describing the cavitation process, then you will receive an answer how to solve this problem. Therefore, I will only say that cavitation processes are primarily energy. And these energy processes are orders of magnitude higher than the compression and combustion of hydrocarbons. Therefore, cavitation is very easy to use to transform water, especially sea water, so that it "burns". The background noise is another matter. Therefore, the propellers can be easily installed not in an open environment, but in any part of the hull inside. And even if such an effect will have at least some place, then oxygen-free power plants and the propellers themselves will simply work at low speeds. The main thing is that they are energetically orders of magnitude more efficient than any of the screws.
              The issue of connecting the solar battery and the propeller is that the power consumption of the new device radically changes the arrangement of the issue of energy consumption and energy efficiency. With an increase in rotation speed, a screw consumes proportionally more energy, and a new device, on the contrary, with an increase in rotation speed, the energy output on the rotor shaft increases by orders of magnitude. And from the critical moment, depending on the properties of the flow of the outflow, it generally turns into an engine with an "external combustion chamber", so to speak. And even these cavitation process sections in the flow convert the kinetic energy of the flow into an even higher-energy process.
              Even with about 10000 rpm on the motor shaft, the device produced practically no perceived sounds, except for the hum of the bearings. But there is a cardinal decision on the issue of the bearing, so that it is really "eternal" and with the accepted loads an order of magnitude higher.
              In general, cavitation is characterized by regular algorithms of the process itself. In addition, it is a continuation of the turbulence phase. And also cavitation processes are a prerequisite for the next stage. Another thing is that they are fast-occurring, if not super-fast-flowing. But the well-known properties and prerequisites of cavitation allow it to be used with very great benefit.

                Yeah, I see that you have top-secret knowledge on the separation of water molecules into hydrogen and oxygen, which would then burn hydrogen in oxygen. That is, mankind has been struggling with the problem of cavitation for more than a dozen years, solving the problems associated with it, and you have an answer how to use it to turn water into fuel! The whole World is anxiously frozen and expects from you this undeniably archival discovery, which will stand on the same shelf with a wheel and penicillin! What then for implementation delays?
                Here in the article we are talking about replacing the material of the propulsion (screw) with composites and nothing more. There is no talk of any new ways of splitting water or creating a fundamentally new type of engine / mover.
                Can share a link with proofs, what is possible even in theory?

                  I feel sarcasm. However, the solutions are so obvious that, as they say, they do not go crazy for so long that I do not understand what the conversation is about. Moreover, it is the use of composite materials with correctly positioned carbon fiber filaments that can be of great importance for the shift of the area of ​​cavitation destruction. Again, I'm simultaneously talking about all modern innovations in this topic as transitional stages that you can skip and immediately use a full-fledged technology. Sorry, but I won't talk about the theoretical foundations anymore. All these are methods of analyzing complex physical processes. And everyone who wants to at least approach this needs to understand simple things, that "everything and everything" has its place and meaning in the algorithm of the dynamically occurring processes. In any case, there is a fairly comprehensive and complete theoretical substantiation of the proposed control technologies for physical. process and the device itself.

                There is such a thing as sabotage. There are also criminals who, through their inaction, create consequences that lead to disastrous results. Therefore, I appeal to those who really are not indifferent for the future of their country. Understanding many processes comes with time. Such as a direct assault on this future.

                There is no doubt that you are a saboteur and there is a good example of this. I have repeatedly spoken about the impossibility of overcoming problems when achieving hypersonic flight by simple searches for suitable material. And they already openly write that in the lower layers of the atmosphere such flights are accompanied by an increase in the temperature of the hull over 1000 degrees and the appearance of wave oscillations on the surface. And I am discussing specific methods and methods that will allow us to overcome even higher flight speeds. You are just a squabbler and haven’t suggested a single rational thought. You are not even able to reason. Let others draw conclusions.

                In no case do not feed. I understand him perfectly. Indeed, such inventors who are ahead of their time usually disappear. I personally saw a working Meyer cell, where and when - I won’t say, live hunting :). But, without proofs, you can believe a word, or you can not believe it. By cell you can find a lot of information on the Internet. I ask for a reference to the information about cavitation and a new type of engine, but somehow so far to no avail what .

                  You see, but the question is that there are peak design ones. This is the creation of ultra-fast electric motors. The task of creating an object capable of flying at hyperspeed. Problems of processing large information data arrays, etc. In general, all tasks associated with overcoming a certain line of transience. In this regard, it is probably worth saying that any inventions that are positioned as based on new physical principles look stupid. But if we talk about new algorithms for organizing such physical processes, then this will be more true. Because in order to invent something fundamental, it is necessary to have new fundamental foundations for such creations. In general, the crafty of the genius inventors can be determined immediately and unconditionally by what theoretical foundations are embedded in the process that is provided by the device. For example, what kind of ionic space engine can we talk about if there is no energy source of this level? Where is the growth potential and is there a reserve of this energy? Where are the processes for managing the density of this energy? All this is not. The same can be said about hyperspeed flight objects. Of course, you can reach it for a couple of seconds. But this is not serious! And so on. Therefore, from what has been said "it follows" that even a simple idea is very important, at least, to move somewhere. We are talking about a principally new method of analyzing high-volume and fast-occurring, if I may say so, processes. We fully substantiate the reasons for effective work, namely devices, on the basis of new process algorithms in which the initial concepts remain the same. The device itself is simple and technologically not difficult to reproduce. With all this, it provides a completely new quality of the result that we get.
                  In this light, can we talk about the public availability of such information to everyone? In principle, all scientific and technical intelligence of the world is chasing such information. Just everyone can not believe that it is so close and accessible to those who behave correctly.
                  I repeat once again, we do not give a complete and exhaustive solution, but we give that path of searching and already developing and mastering what is known. And this path has the potential for development much further and deeper than everything that science has at the moment. So sorry, but I am the source and there are no links. This is nowhere to be found and will not be popularized. I understand that I am walking on a "razor's edge". If they do not destroy those to whom I am standing in the throat, then they will destroy those to whom I do not get. I bow for this. Respectfully the one who does not live long.

    Due to the creation of a new material structure, the blade will adapt to the flowing hydrodynamic flow depending on the speed

    The phenomenon is probably poorly understood and therefore very dangerous. I remember how a cyclist was broken on "super-duper" composite spokes. The spokes were cut with transversely flying small pebbles and twigs, of which there are a lot on the road. As a result, an instant loss of longitudinal strength, the dude has multiple severe fractures.
    Composites are certainly not susceptible to oxidative corrosion, but delamination and microcracks are unlikely to be avoided.
    In this regard, the statement by the French about the combat readiness of only 20 Rafalees is interesting. Someone knows, is it because of problems with composite body parts?

      In the struggle of the temptation to share information with the fact that common sense still wins, nevertheless it is possible to say and repeat that some constructive solutions can radically change the essence of the whole process on the rotor blades. It turns out a completely different physical process, which allows you to use the energy of the pressure vector and the energy of the centrifugal process and the potential energy of the flow substance.
      It is impossible to break through to designers and developers. They are closed from any contact. Scientific and technical intelligence is not at all interested, since the questions relate to the fundamental foundations and no one has encountered such solutions before. In general, a complete dead end. Therefore, I participate in such meaningless forums. Maybe I think at least someone perspicacious there.
      Ultimately, I can say that the use of composite materials on the propeller blades only aggravates the situation. The lack of understanding of the essence of the processes of ionization of the surfaces of the outflow by the hydro-gas-dynamic flow also corresponds to the ways of finding solutions, which will still lead to "nothing".
      Discussions on theoretical issues do not give an opportunity or a chance to be heard. Obviously a complete lack of tact and tolerance, and ultimately, rationality in the dialogues. Therefore, I only say that such a constructive solution is real and obvious, and this is actually a new basis for creating engines of the future with a new order of traction levels and the absence of a proportional dependence on fuel consumption.

    Another wave to start up the body, like a dolphin ........ A seventh generation biomaterial coating will probably be. If the "ball" is not ruined by this time.
    The skin of dolphins is a miracle of nature, they are able to dampen the turbulence of water at the surface of a rapidly swimming body, reducing the speed of movement - the designers of submarines learned from dolphins, creating artificial skins for submarines. And the dolphin’s skin sensation to the touch is quite unusual, and it also brings joy: it looks as thick as plastic, and when you palm it is tender and soft, it seems thin silk.

      Any physicist should know that at high speeds of rotation of a simple disk (of any material), the disk begins to bend according to algorithms. And in the end, trying to form collapses. Everything is quite clear for smart scientists who "read" the process. And of course the blind do not understand the reasons for this phenomenon. Therefore, the reasons for the wave along the midline of the body of the same dolphin are completely understandable. Such waves not only dampen cavitation, but harmonize the process of water flowing onto the surface.

    Composite materials have been used in military technology for over 40 years, especially in aircraft and rocket science. One problem, poor maintainability, if you can put a patch on a duralumin, well, let's say the wing was shot, then the patch on plastic is difficult to put. And if the bundle, then a complete replacement is needed. But maybe they’ve come up with something new, I don’t know.
