The creation of an air-independent power plant (VNEU) for 5 submarines of the Kalina project is completed, leads RIA News Excerpt from the report of the Rubin Central Design Bureau for 2015

In the Rubin Central Design Bureau announced the creation of the newest power plant for the submarine "Kalina"


Earlier, the director of the Central Design Bureau Igor Vilnit reported that the sea tests of the VNEU should be conducted in 2016.

"As part of the research work" Kalina-Navy "successfully completed work to create a VNEU for non-nuclear submarines," the report says.

According to the designers, “the main advantage of an air-independent power plant is an increase in the secrecy of the submarine and the ability of the submarine to be under water without ascent to charge the batteries.”

As a source in the Navy told the agency, the newest submarine “Kalina” will be laid in 2018.

“The project“ Kalina ”is absolutely relevant for us, this project must be very successful. The head boat will be laid in 2018 year, ”said the source.

It is assumed that the construction of the boat will be engaged in "Admiralty Shipyards."

Help Agency: “The VNEU of the Russian development is fundamentally different from foreign analogues by the method of hydrogen production. In order not to carry high-purity hydrogen on board the submarine, the installation provides for the production of hydrogen in the amount of consumption using diesel fuel reforming. ”

          Strange, but here I agree with you completely and completely.
          Before that, they could not create a normally working engine, they were tormented with a stand (even they could not really get it to work) and then bam - it turns out that already half a year ago, we finished the work and we have a ready engine.

            In general, I wonder why hydrocarbon reforming has proven to be more profitable. As a first approximation, there is definitely no mass, just because of fire safety?

              There were other proposals, but hydrocarbon reform proved to be the safest, most compact, technologically advanced and non-waste.

                Where is the carbon going, I wonder? And in what form? And - even fuel cells need oxygen. Some lie. It was said: "It turned out to be a paradox that the best heat source for non-nuclear submarines based on the Stirling engine turned out to be isotopic heat sources." Translated into Russian - some piece of plutonium with a constant temperature of 900 degrees (as in an American probe) - or something just a little more complicated.

              You probably forgot about the mass of pressure vessels, because hydrogen is stored in a compressed state. In a standard gas cylinder 60 kg of weight, when fully charged with oxygen at a pressure of 160-170 atm, its weight will be approximately 80 kg, and hydrogen is noticeably lighter than oxygen. Draw conclusions. hi

              A barrel under diesel fuel is much lighter than a vessel under gaseous oxygen or hydrogen ... try to raise the oxygen cylinder and thoughts will immediately rush to the right track!

More surprising is Zircon, about which everyone has calmed down recently.

            The reason for the delay was sanctions, but now they have found an option, or the import substitution the notorious still fired. The situation is the same with the movers and power plants of NPO Saturn, so there is about one trend here. VNEU really turned out to be delicate, foreign industrial spies swarm swarm for half a year already. Yes, only a bullet to them in the temple and in the basement to drag, just in case.

              VNEU sawed a lot of dollars and before the sanctions, just now the campaign was finally finished. In general, what interests me the most about this thing is its cost because looking at German boats with VNEK and their price, it would be cheaper if the nuclear submarines of the same size come out with incomparable autonomy and speed.
              In short, this is to say that for me it’s better for my army to build a nuclear submarine, and for the protection of the coastal zone ordinary cheap diesel engines will do, that's all.

            Over the past six months, a lot of things have been secretly deaf.
            On this topic, for example, they do not build Lada, then they build.

              our development allows us to do without a transportable supply of hydrogen, i.e. it is more technological than western.

              1. The "transportable hydrogen supply" is in a bound form in diesel fuel.
              2. We and the United States followed the path of creating a VNU on the basis of diesel fuel reforming. The rest of them looked at Stirling. Japans are evading towards LIAB. However, our installation, judging by the statement of the director of CDB "Rubin" Igor Vilnit, this year will be tested at sea. Really back on the Sorov? For the only "failed non-nuclear submarine" suitable for this is "St. Petersburg". This means that it will be returned to the shipyard and the VNU will be installed. Or they will equip a new case (it is preferable and most likely it will be so).
              3. There is no doubt that the installation is "more technological". But it is also more economical in operation: there is no need to build an onshore infrastructure for the production, storage and liquefaction of hydrogen. And this is a whole plant, which in a threatened period can "accidentally" explode ... Then - sushi oars: "there will be no kin!"

              The main thing - let them build "Kalina" with VNU, and then we'll see who has brighter feathers and longer tusks!

              And it looks like the very element in which the reform of the diesel fuel is going

      The main advantage of the 5th generation Kalina boats should be an anaerobic non-volatile power plant based on a modular Stirling engine. It will make it possible to stay under water without surfacing to charge the batteries much longer than boats with a classic power plant. It is being developed by the Rubin Central Design Bureau, possibly with the participation of specialists from the Stirling Technologies Research and Design Institute. In 2016, the VNEU ground tests were completed, and in March preparations began for marine tests on a special floating stand. Tests will begin on the Baltic Sea in 2016, said Igor Vilnit, Director General of Rubin Central Design Bureau. Upon completion of the tests, and the start of serial production of power plants, they can be mounted on a submarine at any stage of construction, thanks to its modular type. The principal difference between the new VNEU and its foreign counterparts is that the hydrogen supply is not on board but is produced in the volume of consumption by reforming diesel fuel in a special installation.

For ships with a Stirling propeller shaft, this is good, because it has low revolutions, and for an electric motor it is not very .. There may well be a turbine.

        Our VNU has nothing to do with Stirling. Hydrogen is produced for a direct chemical reaction with the formation of water and the extraction of electricity for the operation of a single ED, as well as for tamping the battery in a submerged position. Most likely, the boat will go under the AB to "jump". And patrolling - at the VNU with battery charging.
        The main difficulties were not only with the "reactor", but also with a single ED. It looks like the crisis is over.

        And think about why those who have been using anaerobic installations on combat boats for several years, so to speak, "have already eaten the dog," will eventually switch to batteries of updated lithium technologies?

        So why should we again go on a foreign path if VNEU is not a panacea, as it turns out?
        Why step on the same rake. which have already been attacked by the Swedes, Germans, Japanese?

        They will be pledged only in 2018, if again something does not affect the timing. Then they will build for three years, then finish. As for example the same "St. Petersburg". Well, modestly by 2025, will something really be drawn? There were many promises and statements that everything is going ... So it's better to believe the facts, and not the statements of the general storyteller from Rubin.

        There are not only vague phrases. There is frank unprofessionalism of both physicists and theorists. Efficient non-volatile energy installations are possible on plain sea water. Water can simply be trivially included in a thermodynamic cycle with a unidirectional vector of the process. This means that the engine can perform the function of transforming water into a short-term state of separated hydrogen and oxygen, and this step will also be included in the process of creating the angular momentum on the rotor connected to whatever you want. Moreover, the screw replaced with this new device can in a certain mode work perfectly without harmful cavitation effects. That is, in one case, on the same device and the principle of its operation, cavitation can be increased and used as an engine device, and in the other case, cavitation can be leveled by reducing turbulence on the blades by lengthening the laminar flow period. The question is not even that the proposed technology can already be applied immediately, but that you need to grab it as a thread that defines a completely new direction of research, but also the application of new algorithms in the process of creating new engines.

            Somehow too pathetic! In general, it is incognito that allows you to be quite frank. In addition, it is worth noting such an important aspect that the ability to fantasize is very different for different people. This is a sign of the dimension of imagination. And believe me. that a person cannot even fantasize more than it can be associated with his ability to represent the world such as his network. So my world of perception is different from the world of perception of other people - and nothing more. Therefore, I am neither better nor worse; I am simply a place in space with my own properties and abilities and nothing more. Everything else is apparently an illusion and abstraction, based on developed or undeveloped levels of emotional reaction to what is happening. So a person apparently sometimes needs to be able to see the world without emotional accompaniment. See the world as information, consistent with its intuition and mind, or not consistent. And this just needs to be justified.

            It is not your right to tell me. I do not violate the rules of the forum. Moreover, I hope to hear the answers of smart people. And I remind you that the known properties of radioactive metals to generate heat can be obtained from any other metal. But you are not given to understand. But global trends and leading world physicists understand the prospect of ultrahigh-speed email. machines and, accordingly, the achievement of ultrahigh speeds on the rotor. Therefore, for those who aren’t smart, I’ll remind you that radioactive material, among other things, also has radial radiation, which is generally simple for people like you, and a linear segment placed in an ultrahigh dynamic process (with your mind, you can’t add imagination to see simplicity process and the mechanism of its organization) will allow radial radiation to turn into linear. For what ? You also do not realize. Cavitation is a process that precisely allows you to hold high speed and create a reference flow in the rotor of the device. In general, if you still answer ugly, then I do not have to climb into my pocket for answer words for a long time. You are simply idiots and I am shocked by your stubborn stupidity. You are not able to understand the simplest mechanisms of transformation of matter.

                Firstly, if you are not even going to admit that you were the first to be rude, then what arguments can be discussed. I speak that language. which they impose on me, of course, if it is appropriate for the circumstances. Secondly, you are a man, apparently a military man and must understand that I am not delirious and talking about a mechanism that is absolutely obvious in a person’s perception. A huge number of obvious phenomena, when the same nebulae in the flowing stream of an airplane wing, cavitation not only on the blades, but also on the hull of the boat leaving a mark in sea water. These are all processes of one phenomenon and algorithm, which can be simply turned into a convenient and simple energy process in a power plant. I’m not trying to impose a theory on my fantasies. I’m talking about what can be done because it is simple and obvious, and we have already tested the reality of the effect under those conditions that we can do. But as they say, if smart, then there should be a lot, and I understand the importance of the technology I'm talking about. Now imagine that I will post information openly. You Russians are clumsy and volatile in the decision-making mechanism, so for now, the Chinese will think. the Japanese, Americans and especially Germans will take from under their noses what essentially belongs to you. The technology I'm talking about is the optimized technology of the Germans that they developed in World War II. I was somehow brought to a person who was introduced as a general. So when I proved to him that Schauberger’s key devices have the same basis and the process algorithms that I’m talking about, he told me that a huge number of documents are stored in storage rooms and they simply cannot be understood or read. And he immediately suggested that I be a consultant on some issues. BUT!!! Something did not work out. Therefore, you and others should have an idea that the same Germans and Americans have an identical problem. And they all work to solve problems that lie in a common concept for the issue. And I just solved this problem. That's all. Therefore, what a dreamer I am, if you do not own the slightest bit of what is known, if not to me, but to those who, at the present time, are not even a partner, but an obvious adversary. So think about what I can think of you.

If you bought a new wardrobe and money until the next paycheck you have barely enough, then your financial situation to shreds or not? We have large projects and construction projects (worth more than $ 100 million) now simultaneously underway in the region of 70 pieces. These are military projects, and infrastructure, and industrial, and agricultural. And everywhere money is needed, respectively, from time to time, their shortage emerges in some places, which they begin to urgently solve. Naturally, if you cancel a couple of dozen projects, then there will be more free money and there will be no problems. However, all the projects are needed and how to decide what to freeze - the construction of submarines, ships or power plants, or bridges and roads, or import substitution? It will be easier in my opinion after 2018 - there the World Cup will be held, and part of the construction projects will end, and many import substitution projects will end, and so on.

Isn’t it easier to take outboard water and decompose it into hydrogen for the engine, and oxygen for life support?

    The fundamental difference between the new VNEU and its foreign counterparts is that the hydrogen supply is not on board but is produced in the volume of consumption by reforming diesel fuel in a special installation.

    This is a great solution, because storing hydrogen is another challenge. It’s very painful, infection. Yes, and less explosiveness.

      Here you can argue. Their hydrogen cylinders are located outside of a solid casing; our hydrogen will be stored inside.
      The only advantage of our method is that there is no need to build a complex onshore infrastructure - a hydrogen production plant, its storage, transportation and pumping, and in terms of efficiency, reliability and safety, our method loses, therefore, the installation was "tormented" for so many years. On the other hand, the submarine can be based in any convenient place, not just near a hydrogen source.

        Here I come from the same. For me, pure hydrogen is better, especially since it is stored in porous structures, with a large area of ​​reactive polymer in cylinders, almost chemically bonded, and not particularly fluid at temperatures less than 20 degrees Celsius. Making a cylinder for 200-400 atmospheres and getting hydrogen in the reactor is an order of magnitude easier than making complicated submarines, and even more overall ones.

    The main advantage of the 5th generation Kalina boats should be an anaerobic non-volatile power plant based on a modular Stirling engine.

    The main advantage of the Stirling engine, which works on the principle of external combustion over a conventional ICE, is its low noise. At the same time, combustion still occurs, which means that an oxidizing agent is needed anyway (it doesn’t matter if there is oxygen in the air, or whatever). So you need a supply of oxidizing agent. And then you need to put combustion products somewhere. If overboard, then the pop-up gases and, as a consequence, the unmasking effect. Not really, I can imagine how all this will be. At the same time, at the end of WWII, the Germans developed submarines, where the oxidizer required for the operation of the internal combustion engine was stored in special containers placed between the strong and lightweight submarine cases. The idea worked, but with the advent of atomic submarines it became irrelevant.

To heat the catalytic reforming reactor (rather than reforming, as some write here) in the required volumes and to the required temperatures, cheap salt catalysts do not roll, and platinum ones make the operation of such a plant expensive. Moreover, as a result of the catalytic reforming of hydrocarbons, reaction by-products are still formed. Where to put them in a submarine? Reuse will not work.

        I don't even really want to talk. Let, for the sake of curiosity, estimate the characteristics of an installation in which you can heat water to such a temperature and at the same time fit into the dimensions of a submarine. And the hydrogen that he receives in this way will cost almost more than the platinum catalyst. To all appearances, the concept of "catalytic reforming of hydrocarbons" is akin to "nanotechnology" for many. sounds beautiful, but mysterious and incomprehensible.

I am much more concerned about the level of technical literacy of people who believe that there is some cheap, effective and safe way to produce hydrogen. The only one that at least approximately corresponds to the needs is to obtain, by reforming, a hydrogen-containing explosive gas bound to CO in a safe concentration from coal. However, the amount of coal needed to meet the needs of the submarine power plant in this cycle is large, and most importantly, by-products of the reaction still arise, which still need to be put on the submarine somewhere. In any case, everyone talks about VNEU as if the law of conservation of energy no longer exists.

          This is the essence of a harmonious process, which consists in the fact that HYDROGEN needs to be separated or isolated as a stage in a dynamic process. It does not need to be isolated, collected and then used. It is needed as a very short-term stage before the next one, when it again enters into a reaction with oxygen. Why hydrocarbons are not entirely acceptable, to put it mildly. Moreover, the products or results of such interaction and reaction should be in a non-stop and without organizing process of introducing a new portion of the flow for the reaction and its output, or in a closed cycle, and this process should and can be included in the reaction of the machine as a newly created torque on the rotor shaft, due to the kietic energy of the stream. In other words, this is what I say all the time that the complexity lies in the fact that simultaneously the energy of the kinetic hydro-gas dynamic flow can be formed and the potential energy of this flow can also be used as a process in the very matter of the flow. Then it’s not that it’s useless to talk about efficiency, you can generally have a clear understanding of the nature of what is happening in excess of a single energetic process, but controlled, and not on the concepts of "perpetual motion machine".

In addition, you are deeply mistaken that space is an insulator. if applicable to that quality of energy that a person uses, then yes, but for a different quality, this is far from an insulator. The ocean, on the other hand, is a system that ensures planetary equilibrium due to a complex of metabolic processes, and the mechanism of such metabolic processes directly depends on the interconnectedness of WATER as a substance with magnetic fluxes around the planet.

    There are not only vague phrases. There is frank unprofessionalism of both physicists and theorists. Efficient non-volatile energy installations are possible on plain sea water. Water can simply be trivially included in a thermodynamic cycle with a unidirectional vector of the process. This means that the engine can perform the function of transforming water into a short-term state of separated hydrogen and oxygen, and this step will also be included in the process of creating the angular momentum on the rotor connected to whatever you want. Moreover, the screw replaced with this new device can in a certain mode work perfectly without harmful cavitation effects. That is, in one case, on the same device and the principle of its operation, cavitation can be increased and used as an engine device, and in the other case, cavitation can be leveled by reducing turbulence on the blades by lengthening the laminar flow period. The question is not even that the proposed technology can already be applied immediately, but that you need to grab it as a thread that defines a completely new direction of research, but also the application of new algorithms in the process of creating new engines.



    ROW SCREW CAVITATION
    - the phenomenon of formation at the backs of the blades of gas bags, consisting of water vapor and air, at significant speeds of rotation of the screw. Gas bags disrupt the continuity of the fluid flow and thereby reduce the pressure in this area of ​​the blade. Owing to K., the axial emphasis and torque are reduced. The efficiency is drastically reduced. In addition, with K., the screw surface is destroyed. The main measure of struggle against K. is the increase in the area of ​​the blades.

      You will excuse me, but since you wrote, and wrote from the words, like knowing people, but all this looks like babble-nothing concrete, there is nothing physics or mathematics in what was said. Therefore, I can only briefly answer that for different WATER by the presence of the same salt impurities, its temperature and other properties and the state of water with a variable pressure discharge of it, as well as on the surfaces of the discharge material of different conductivity levels, the so-called cavitation phenomenon occurs. It is worth saying that cavitation also occurs on that part of the flow surface where the flow turbulence is higher, namely, its ability to ionize the flow surface is higher than the same conjugated surface with a large radius, etc. That is, cavitation occurs on that part of the flow surface, if so, where the flow rate is higher and the surface is more highly charged. Therefore, the destruction of the surface of the outflow always has a certain configuration and such a focus of cavitation always takes place relatively long blades. Now, with regard to the causes of cavitation regarding the properties of the liquid itself, as a medium of hydrodynamic flow. On the surface of an open propeller blade, propeller or turbine blade, whether the designers want it or not, cavitation will always be on the surface of the outflow plane and no curvature or "saber" shape is able to resist such a phenomenon. Therefore, so that the ionization of the outflow surface does not decrease, but rather increase, and at the same time the cavitation phase itself occurs not on the blade, but on its tip, which means that this can be distinguished as a "combustion chamber" in which the higher the cavitation, the higher the radial explosive effect, which will always be directed tangentially and in the direction of rotation of the rotor axis. That is, cavitation will additionally rotate the rotor and without destroying the surface of the expiration. Everything is so simple and obvious, but for some reason everyone is doing the exact opposite with the negative effects that they receive in the form of what you meant as a decrease in efficiency and cavitation destruction of the discharge surface. Sorry, I don’t describe the subtleties because the process is complex and how hydro-gas-dynamic flow enters the rotor and how it exits is no less important. The current solution is completely thoughtless and neglecting all the laws of physics. At the same time, I note that a correctly set process in appropriate algorithms will allow using the properties of WATER as a fuel, will allow water to deactivate from radioactive contaminants, and desalinate in large quantities. Just imagine that at a supersonic speed of the water flow on the periphery of the rotor, you use water to convert this water from natural temperature to millions of degrees and not some part of a separate stream stream, but all, in its entirety. This is both an engine and a converter of water as a substance. At the same time, I add that the cavitation effect is a complex physical process and it is not calculated, but simply used to one degree or another relative to the goal and task. But a mathematical model can still be constructed as a complex process of highly dynamic fluid or gas outflow, in which not only kinetic, but also potential energy and substance properties are transformed that determine the flow. My personal opinion is that in addition to solid, liquid, and gaseous and plasma, the state of all these media should be distinguished as their state relative to the dynamics of contact between them.

    Laminar and turbulent modes of fluid motion

    fluid movement
    Numerous experimental studies of moving fluids have established that there are two modes of fluid movement. The most complete laboratory studies of the modes of fluid motion were carried out by the English physicist O. Reynolds in a facility (Fig. 10.1), consisting of a tank of water





    Fig. 10.1. Installation diagram for demonstrating fluid motion



    a glass tube 7 with a tap 8 and a vessel 4 with an aqueous paint solution, which can be supplied with a thin stream into the glass tube 6 when opening the tap 5. The filling of the vessel 1 is carried out from the tap 2 with valve 3.

    At low water flow rates, the paint practically does not mix with it and the layered nature of the fluid flow and the absence of mixing are visible.

    The pressure gauge connected to the pipe 7 (not shown in the diagram) shows the invariance of pressure p and speed v, the absence of oscillations (pulsations). This is the so-called laminar flow (from the Latin word lamina-tape, strip), i.e. tape, layered.

    With a gradual increase in the speed of water flow in the pipe by opening the tap 8, the flow pattern does not initially change, and then at a certain speed its rapid change occurs. A stream of paint begins to mix with the flow of water, vortex formation and rotational movement of the liquid become noticeable, and continuous pulsations of pressure and velocities in the flow of water occur. The flow becomes, as it is commonly called, turbulent (from the Latin word turbulentus - random).

    If you reduce the flow rate, then the laminar flow will be restored.

    So, a laminar flow is called laminar without mixing particles of liquid and without pulsation of speed and pressure. With this flow, all fluid flow lines are completely determined by the shape of the channel. In laminar flow in a pipe, all streamlines are directed parallel to the axis of the pipe. The laminar flow is ordered at a constant pressure of a strictly established flow. The laminar regime is observed mainly during the movement of viscous fluids (oil, lubricants, etc.), and less viscous fluids during their flow at low speeds.

    Turbulent flow is called accompanied by intense mixing of the fluid and the pulsation of velocities and pressure. The motion of individual particles is chaotic, random. Along with axial displacement, rotational and transverse displacement of individual volumes of liquid is observed. This explains the pulsations of velocity and pressure. Reynolds found that the main factors determining the nature of the fluid motion are the average fluid velocity v, the diameter of the pipeline D and the kinematic viscosity of the fluid n. Given the influence of these factors, Reynolds proposed a digital dimensionless criterion for determining the regime of fluid motion

    Re = vD / n,

    where Re is the dimensionless Reynolds number or the Reynolds criterion.

    Knowing the parameters included in the right-hand side of this formula, we can calculate the value of Re by calculation.

    The speed at which for a given fluid and a certain diameter of the pipeline there is a change in movement modes is called critical.

    Experience shows that for pipes of circular cross-section the critical value of the Reynolds number, at which the turbulent regime of fluid movement begins, is equal to 2320. Thus, the Reynolds criterion allows one to judge the regime of fluid movement in the pipe. At Re <2320, the motion is laminar, and at Re> 2320 - turbulent motion.

      Complete amateurism. The movement of a liquid is an energetic process and it must be considered from completely different positions. I will only mention the most important processes of liquid outflow. Many people think that the fluid velocity in the near-wall zone or directly at the contact of the flow and the outflow surface is equal or tends to zero. It really tends to zero in the longitudinal vector of the flow, but it is maximum in the perpendicular vector. Therefore, the same "POCKET track" is an algorithm when the river water flow changes the vertical vectors in a certain area to longitudinal along the circumference. And the higher the flow velocity relative to the surface, the higher the density of the magnetic force interactions between them. This is shown by experiments and the same COAND effect, when the outflowing liquid from the pipe ionizes it and therefore "turns back", but in fact it simply follows the flow of magnetic forces and their flow. Exaggerated ee Reynolds constants generally disorganize the understanding of the complex process, and most importantly, they do not show the reasons for the change in laminar flow to turbulent and subsequently cavitation and with sonoluminescent effects. Therefore, low-potential processes can still be calculated with errors and tolerances and Reynolds constants, but what will you do in other energy modes. Think for yourself. I do not even position the process description system on functions of constant value of a number. You won't understand anyway, because you don't want it yourself. By the way, plasma behaves in exactly the same way as the flow of liquid or gas.

    You are clearly smarter than all smart ones, especially claiming that MANY THINK and do not rely on knowledge of basic sciences.
    I actually wondered about what the movement of the submarine to the laminar mode is related to if the submarine does not stand still and moves and the concept of a laminar flow of fluid and the movement of the ship as well as the shape of the propeller and turbulence are generally not relevant here. Hydraulic laws and then than many people’s knowledge is built, you don’t think so, and so on, although this knowledge was invented and used by all university lyceums and other educational institutions, and here you are probably the most intelligent at Harvard, and there’s a different vision for the knowledge of man and another more abstract .
    The outflow of fluid in relation to the movement of a submarine that itself moves in the aquatic environment is everything you respected is upside down, the ocean is moving and the boat is standing?

Therefore, is it really not clear that the process of transformation of the substance of the flow through its potential energy is obvious and there are stages of such a transformation from laminar motion to turbulent and further to sonoluminescent, and you and your contemporaries solve the problems of analysis of these processes applicable only to laminar. And if this is so, then you just need to change the methodology itself to each level of the dynamic state of this environment, its flows. That is what I am talking about.

    Stirling's efficiency is about 46% higher than that of a diesel engine .., and the "ideal" "working fluid" is hydrogen under very high pressure - this is far from a fountain, but a good hemorrhoid, if we also take into account its destructive effect on metals and seepage ..

    Looks we studied in different educational institutions


    You studied in different schools, live in different countries (if Ukraine today can be called a country) and exist in different dimensions. Gridasov (1) has already learned to live forever. While it turns out ...

    I didn’t say anything bad about Ukraine! so it’s part of me even though I’m not amazed there, but the meanings and concepts and who and where I studied it also has nothing to do with the question, the essence of the conversation is that you can’t turn the meanings and terms, do not call white black and vice versa

    In principle, Stirling is the principle of operation of a home refrigerator, but vice versa .. Freon is poured into the refrigerator ..
    In the refrigerator we need cold, and in the Stirling engine we need the rotation of a generator (electric motor) ..

    There is a professor in St. Petersburg; he has long been remaking Zhiguli engines in Stirling engines.

    And on these Lada flies into space. laughing

    In the days of my distant youth, I had to read an article by Shkurat in the magazine "Young Technician, or" Technique of Youth ", where he experimented with a boat motor, translating it on the topic of Stirling and gas ..

    On this topic, for example, they do not build Lada, then they build.

    And what has the 677th project to do with it? We are discussing the Kalina project - not to be confused with the VAZ model!
    Decent news, despite the doubts of members of the forum good !

    Well, how to build it and write ...! Nerves do not need to be battered ...

    Strange, but here I agree with you completely and completely.
    Before that, they could not create a normally working engine, they were tormented with a stand (even they could not really get it to work) and then bam - it turns out that already half a year ago, we finished the work and we have a ready engine.
    Vague doubts torment me. (WITH)


    I'll tell you this .... I'm more interested in who he was snooped on with wiretaps, the Germans, the French, or the Swedes ....

    But what about the widely advertised "Lada"?

    Yes, she died so much that the modified and perfected project "Lada" with VNEU was renamed "Kalina".
