Fullerene coating created: China announced a solution to the problem with engines of 5th generation fighters

161

China said it had solved an engine problem that had hampered the development of its 5th generation fighter program. The problem was that when a certain temperature was reached aviation the engines lost a significant portion of their thrust. This problem was typical for the WS-15 aircraft engines, which are planned to equip the new generation J-20 fighters. Today, most of these fighters use Russian-made engines.


Chinese state media report that a new turbine coating material has been developed to "fill the technology gap." From publications in the Chinese media:

This material will ultimately help increase the thrust of the engines when reaching the operating temperature regime.

It was noted that a specially membrane coating is being created in turbines that can withstand temperatures up to 1800 degrees Celsius.
Chinese press:

The technology was developed by specialists from Hebei province. The material can withstand temperatures up to 1,8 thousand degrees Celsius, protect against corrosion and provide higher traction. China is breaking its dependence on aircraft engine technology.

At the same time, in China, it was previously constantly said that they intend to overcome dependence on Russian engines and technologies for their creation. For this purpose, Chinese companies invested in Ukrainian Motor Sich in the hope of obtaining documentation of technological processes.

The Hong Kong edition of SCMP indicates that China was forced to buy Russian engines for years, and the WS-10 and WS-15 remained unfinished.

The new coating is based on fullerenes, and its warranty operation in engines will be about 2 thousand hours.

Chinese press:

Among other things, fullerene membranes will allow doubling the efficiency of aircraft engines when operating aircraft in low humidity conditions, including in airspace over deserts.

    In between, "a new turbine coating material has been developed that" makes it possible to fill the technology gap. " and bringing new aircraft engines into series is a big abyss.

      I wonder who the Chinese comrades have communicated the technology to? Maybe Biden helped?

                So yes)))) the problem of temperature at the inlet to the turbine has existed for as long as there has been a turbojet engine. Everyone who develops and manufactures such engines is struggling to solve this problem - mattress covers, the French, the British, the Japanese, the Russians. Are the Chinese the smartest? I am tormented by vague doubts))))

                  Already the statement about such a temperature, somehow does not strongly inspire, because if you recall the theory:

                  1. The value of the gas temperature in front of the turbine is limited by the strength of the turbine blades. In modern engines, it lies in the range: 1100-1300 K.
                  (The capabilities of a single-stage turbine are limited by the maximum (critical) pressure drop in the nozzle apparatus when the flow velocity reaches the speed of sound at the outlet from it (the critical section of the oblique cut). This pressure drop (it is equal to about -2) ensures the adiabatic work of gas expansion
                  Lad ext. ≤ 25000 - 30000 kg m / kg., At a gas temperature at the turbine inlet of 850 - 960 C and a circumferential speed at the average radius equal to U = 350 - 370 m / sec.);
                  2. At the exit from the combustion chamber, the temperature of the gases to ensure the strength of the turbine blades should not exceed: 1100-1300 K.
                  And why did they need materials for coating with temperatures up to 1800 C !? Something is a strong turbojet engine, apparently ... there is a ramjet engine, some are trying to stick in with the last stage ... wink

                    PRVD works a little differently. How they are going to combine them I can not imagine. The turbine there is most likely two-stage, since the compressor must operate in both subsonic and supersonic modes. then there should be HPC and LPC, respectively, and two stages at the turbine.

                      I meant a hybrid installation with a common nozzle, there will be high temperatures (but you can raise the altitude and speed in the afterburner mode for a fighter), where coatings based on all fullerenes can be used, otherwise there is no sense in this, and the cost of such a nozzle or a nozzle attachment for a turbojet engine, will be a little transcendental ... In Soviet times, they also tried to cross a "rhino with a bulldog" - a straight-through with a turbojet engine, for a multi-mode system, but it was not very set ... then, and now, new modeling technologies physical processes and materials that did not exist 50-40 years ago, in aviation and not only in it!

                  The problem is not in the temperature at the turbine inlet (the higher it is, the greater the efficiency of the installation can be obtained), but in the material that can withstand these temperatures.

                      I do not understand what you were trying to say, but it seems you are confusing the cause with the effect.
                      The temperature that the turbine can withstand is limited, which imposes a limitation on the amount of thermal energy supplied to the working fluid in the combustion chamber, and this leads to a decrease in the work it does during expansion.
                      Increasing the permissible temperature of the working fluid at the turbine inlet is one of the main directions for improving the turbojet engine.
                      Therefore, we need materials for the blades that can withstand high temperatures.

                        The pressure difference at the inlet and outlet, the adiabatic work of gas expansion, affects the efficiency, in cold air any gas turbine engine works better and more efficiently than in hot air with a high temperature, I think there is no need to tell why ...!? And why, for example, in a VTOL aircraft flying at the present time, such as even a middle-aged British Harrier, for 90 seconds. work in vertical hover modes, use almost 300 liters. water to cool the turbine and the combustion chamber ... surprisingly !!!

                    I said the same thing, only in different words. The temperature of the gases at the turbine inlet must not be increased, because the turbine blades will not withstand, although there are already heat-resistant alloys with a high nickel content.

                I am sure that in the next 2-3 years the Chinese will be able to make an engine similar to the "117", and, possibly, the "product 30" - look how technological production in China is growing thanks to the American sanctions. I believe that only continued cooperation in the field of engine building will help us keep up with them in the foreseeable future.

              is there chauvinism here?

              In the United States, in IT companies 20 years ago, I was faced with a persistent opinion that the architectures of complex systems are genetically better than whites (Russians in the first place) develop.
              And the Indians and Chinese - they write the code quickly and accurately.
              Therefore, in multinational collectives where this point of view took place, responsibilities were distributed in a certain way.
              And this is not racism, but rather the most efficient resource management.

                  All this is a matter of time. They will have their own scientific schools and technologies, which you and will soon buy from them. Remember the state of the Chinese industry 30 years ago. A gigantic work has been done by the industrious people, and the result is obvious - now it is the second economy in the world. I also want to remind you that Soviet Russia in the 20s and 30s often acquired Western technologies in a not entirely legal way. Theft of technology, industrial espionage is quite common in our time, and not only Chinese comrades are guilty of this.

                    They will also have their own scientific schools and technologies, which you will soon buy from them - We will not, since we have our own developments as materials and solutions, and China, as it was engaged in copy-paste and hybridization of our and Western technologies and developments, will continue to do this. because it is much cheaper and easier than creating it yourself from scratch.

                  For a country to become a great power, to be able to pursue an independent policy, to defend its interests in the world, it must:
                  1. Produce your own "iPhone", which will be bought all over the world;
                  2. Produce your car, which will be bought all over the world;
                  3. Have a strong currency for which other countries are ready to buy goods;
                  4. Have a strong and modern army and navy;
                  5. Have a highly developed defense industry;
                  6. Possess technology

                  Chinese scholars say this about China of the Qin era and post-Qin, that is, the current one. And the inventions made are a distant past. Since then, the Chinese have changed a lot.

                  By the way, typography did not come to Europe from China. There are serious doubts about gunpowder. It is a fact who came to etmou in the Celestial Empire, but China did not send anyone. They have always treated non-Chinese like barbarians, not eager to share knowledge.

                    The Qin Empire is 200+ years BC. the same gunpowder appeared much later. All sorts of plows there, seeders and other things that moved life. I do not believe that Sinologists can even think of this, and not just say aloud, excuse me. Only stoned bloggers if only.

                      I was wrong, not the Qin, but the Qing era. Although the changes in mentality began earlier. It's just that under the Manchus they finally took shape.

                      All Chinese inventions are at least 1500 years old. And then what?

                      "not to believe", you need to know at least one domestic specialist in China. And not only his surname, but also his research.

          It's not that someone is dumber and someone is smarter. Each nation has its own strengths and weaknesses. The Chinese are very disciplined, hard-working, and if they can, they hone their skills literally to perfection. In this regard, we, for example, have a lot to learn. But it is precisely this discipline that does not allow them to go beyond the designated framework. Out-of-the-box thinking in Podbenesnaya was not welcomed for many centuries.

          And this is the problem that Xi wants to solve. Whether it will succeed or not is another question. Something is already working out, but here we are talking about breaking the mentality as a whole. And this is a daunting task.

          The hucksters will not bring down the CCP, this is their party. The Chinese have another "Achilles' heel" - there is no opposition to the hucksters from the hard workers. There are no strikes, no trade unions. While everything is fine, their bike is turned away from the left side of the road, the handlebars are turned to the right. But soon they will cross the middle of the road and roll to the right cliff. And there will be no one to turn the steering wheel to the left again.

            We moved out already. There is no, in fact, any communist party, no more signboard, and there are no trade unions. Chinese specifics. Some hard workers, bulging zenki, tearing the navel in three jobs at the same time. Worse, perhaps, than in the Russian Federation. We somehow survive. There, the authorities and public opinion will not allow at least a little relaxation. Die, but plow the plot.
            I talked a few years ago with a Chinese, and spoke pretty Russian. "With us, in comparison with your life, hell, I think to stay." He left all the same.
            By the age of 70, he will probably have a rest. laughing

        No, one day the Chinese will cover up their NEP, then they will jerk off, I'm sure. And they have already gone through "perestroika", so it will cost. Sooner or later, the planet will be undermined. I also hope to get a party card of the RCP (K) -Russian Communist Party of China laughing

      Taking into account the fact that de jure they are building communism there (de facto it is clear that they have capitalism there too), and we are diving deeper into capitalism, sooner or later China will have questions for us.

          These are not dogmas, this is the base. What distinguishes social and social relations. And not any semitones, concessions under socialism, the huckster-money-grubber are not permissible. Personal material enrichment is a crime against the foundations of a society of equals and is punished immediately and inevitably. Having retreated from this, we lost the Country, having received a gangster-fraudulent education. The Chinese have created a slave-owning state in general, where it is considered bad form to work in fewer than two places, from dawn to dusk, even at night.
          There was no exploitation in the USSR. I sent any chief in the forest if he tried to force me, violating the Labor Code. The state was on the side of the working man, and the party leaders were put in the role of arbiters. Delicious rations and a minimal set of privileges were enforced. With their help, it was possible to drive a bureaucrat of a non-minor rank into a stall if he violated the principle of the dictatorship of the proletariat. I used it personally. Well, the period before the coup was no longer socialism. Immediately, the working man felt a change in attitude towards his freedoms, and vice versa, the huckster tribe raised its head.

And without private production and the same huckster there will not be a wide range of products and there will be a technical backwardness of the whole society, which the USSR demonstrated as an example - toilet paper began to be produced in 1969, for comparison in the west, ATM machines began to be produced in 1967 and otherwise the same individual ideas and proposals in a planned distribution economy built on top of it are considered, you can come up with anything on an individual basis, but it is almost impossible to introduce this into public life, which is why all our iPhones never came out of the garages of scientific research institutes and design bureaus.

      In any case, it is obvious in many actual manifestations that there are simply no such declared huge reserves of the population. Why is difficult to say. First, about 40 million Chinese have left the country. Secondly, the period of prosperity of China after ww2 was rather short, during which the population cannot triple. And after the war, the population was at the level of 430-450 million.
      Of course, 800 million is also a lot, but still almost half as much.

      and were destroyed with Chinese diligence - like sparrows under Mao.
      the same three kingdoms - as a result, they massacred and killed 90% of the population. The same thing happened with documents and cultural artifacts. Archaeologists excavate thousands of armor, blades and other military belongings, but there are very few carriers of other information.
      There is a lot of speculation about Chinese culture, but cross-reports from neighbors say that China is no less than 2.5 thousand years old. The remains of ancient Chinese ships were found even in Africa.
      Another problem in Chinese history is that there are a lot of myths that lend themselves only to interpretation, but it is impossible to directly understand what it was.
