China announced a “breakthrough” in creating an engine for the J-20 fighter


China announced a “breakthrough” in creating engines for the new generation of J-20 fighters. We are talking about power plants marked Xian WS-15.


It is noted that the days when all Chinese J-20 fighters (and not only them) will be equipped exclusively with Chinese engines, "just around the corner". At the same time, the PRC reminds that at the moment the mentioned fighters, which were part of the PLA air force, are equipped with engines of Russian production (the AL-31 family).

On Chinese TV, it is stated that during the tests, the engine of local manufacturers WS-15 (Turbofan) "surpassed the AL-31F in a number of key parameters."

Meanwhile, an article appeared in the American weekly Jane's Defense Weekly that stated literally the following:

Chinese manufacturers did not have time to prepare their own engines, and therefore, J-70 fighters with Russian aircraft engines were used at a military parade in honor of the 20 anniversary of the founding of the PRC. This disappointed China's military experts.

In China, evidence has previously emerged that three prototypes of WS-15 engines under the code designation XX15 have so far been created. For him, as indicated, a transforming nozzle is used. This is a double zigzag edge, which is largely borrowed from foreign manufacturers of aircraft engines.

According to the plan, WS-15 turbojet engines should provide thrust at the level of 14,5 thousand kgf at a turbine temperature of 1400 degrees Celsius. At the moment, Chinese engine manufacturers for fighter aircraft aviation encounter such a problem as a sharp decrease in the thrust of the power plant when the turbine temperature reaches the operating parameters to ensure the above thrust level. In other words, instead of providing the engine thrust record-breaking for the Chinese military engine building, temperature increases bring thrust indicators to values ​​that are inferior, for example, to the same AL-31F (its afterburner thrust is 12,5 kgf). In this regard, it is not entirely clear by what "key parameters" during the tests the Chinese engine surpassed the Russian one. The “breakthrough” is considered to be the selection of metals resistant to high temperatures and their difference.

    Well, sooner or later, anyway, its own school of engine building should be formed.
    Why not do something really outstanding?
    But what is really hiding behind victorious reports? This mystery is great ...
    First of all, the Chinese with the resource had pain.
    Maybe they managed to bring the resource to an acceptable level.

      Only less expensive, as we have in the USSR .. We actually started from scratch!
      The Chinese people are hardworking, but very cunning .. As if they had not outwitted themselves .. hehe
      The main thing is to remember that they owe all this to Stalin and the USSR ..
      And then they would be sitting there in slums opium smoking English .. hi

          Yes, for any engine passes as a secret. And secrets in China are treated as they should.
          So for "surpassed in many respects" can be hidden and a real achievement, and misinformation.
          Very soon, the real performance characteristics of Chinese engines will appear in the media.

          On the Nord Stream 1 stand the Rolls Royce compressor (I saw it myself and even have a photo of the box), but on the second thread?
          And it’s better to keep silent about the fifth generation of mattresses - the restriction on 50 seconds overhead ...

          they studied them specifically and found out that there are only metal alloys there, about 1500, which are not produced in the USSR .. They scratched their heads and began to invent their own (while Stalin gave the order ..)))

            Did the Japanese produce? The Germans handed them the documentation, it seems, for the production of the FAU-1. Operation "Shadow of Yamato" if Bogachev is not lying.

                [/ quote] However, the main part of military equipment (artillery, tanks, aircraft) was developed in the 1930s and by the end of World War II it was significantly outdated, and due to the limited human resources of Japan, up to 50% of the personnel of the ground units were recruited of younger recruits who did not have sufficient military training, and of limited eligible reservists in connection with the transfer of well-trained units, which were considered the best in the Japanese army, to conduct military operations in the Pacific against the United States. With the start of the Manchurian operation, on August 16, 1945, the commander of the Kwantung Army, General Yamada Otzo, ordered his army to surrender, after Emperor Hirohito announced the surrender of Japan on August 14, 1945. Some Japanese divisions refused to surrender, and hostilities continued for the next few days. . [quote]

          Even before the start of World War II, Arkhip Lyulka created the first technical project in the USSR for the RD-1 aircraft turbojet engine. The war made adjustments: work on the RD-1 with the outbreak of hostilities was suspended. And he was also the first to propose a dual-circuit jet engine.

            Well, a very small clarification.
            [/ quote] For the first time, a double-circuit turbojet engine was proposed by the creator of the first efficient turbojet engine, Frank Whittle, in the early 1930s. Since 1937, the Soviet scientist and designer A.M. Lyulka investigated this principle and submitted an application for the invention of a dual-circuit turbojet engine (copyright certificate on April 22, 1941). The first samples of turbojet engines with afterburners were created at Rolls-Royce in the second half of the 1940s, and Conway became the first serial. [Quote]

        In fact, it was under Stalin and the USSR that China was sitting in slums, smoking opium. The bumbling of Mao did not bring any benefits to the economy.
        A steady take-off of the Chinese economy began in the 90's.
        It is possible that it was the collapse of the USSR that prompted China how to do "DO NOT."
        As a result, China did as "NADO".
        And he did it.

          Quite the contrary, successful reforms in China took place at the end of the 70x, in 80x an economic take-off began, and it was China that equaled the political elite of the Union when it tried to reorganize on the path of capitalism. This is easy to trace by the chronology of events, and many politicians of that time directly stated this.
          But in the end, it didn’t go according to plan and it turned out as usual.

            Who and what was equal - no matter.
            The result is important.
            And he is like this: China today occupies the second (or first?) Place in the world in economic development, and the USSR has disappeared from the political map of the world.
            And China occupies this place, including for the reason that it spied on the USSR how to do it. He made the right conclusions and is still thriving today.
            What can not be said about the USSR.

              What does it mean no matter? Due to the permanent regime of repressions and genocides, the Soviet ruling elite has degenerated so much that there was simply no one to reform the country following the example of China. Does it make sense to pour tears over the collapse of such a state? I do not even know. In terms of economic development (GDP per capita), China lags behind modern Russia, to second place it is like ... cancer.
              And China occupies this place, including for the reason that it spied on the USSR how to do it.
              that's for sure, the 20 Chinese had enough years of “successes” in the planned economy to completely disappoint the communist model of the state, the Russians didn’t give up so easily and for 60 years they tried to make candy out of feces ...

            Not equal to China from the word "completely." Although they could weave off topic. The ideal was Europe and the USA, for many - to this day. What is the only well-worn argument about refusing to increase the money supply in order to avoid inflation. Despite the fact that China over 10 years increased the volume of the national currency by 20 times - and inflation remained within acceptable limits. But who is interested in the example of China, in fact ...

              No, they produce a wide variety of cars, both cars and trucks.
              Currently, FAW produces cars of six categories, including light, medium and heavy trucks, SUVs, cars, buses, and small cars. FAW produces cars under its own brands:

              Xiali
              Hongqi
              Jiaxing
              Besturn B50 and B70. The structure of First Automotive Works includes FAW Bus and Coach, which produces intercity and tourist models of buses with its own chassis and engines (capacity from 150 to 241 hp) at its two plants. Buses are offered in various lengths: 8,6 m, 10,4 m, 11,4 m, with the number of seats from 26 to 51.

                    So, with the domestic market in 1,5 billion people, it is not a sin to produce. There are no problems with labor, and with finances, whose legs are growing from there. Objective laws of economics. And after the domestic market, export also appears.
                    In Russia, sorry, the market is at least 10 times smaller.
                    Question as a product.
                    From my experience, the Germans in Shanghai built a plant for the production of special alloys.
                    Now the plant is in free swimming, no longer under the Germans.
                    Those alloys that were produced under German control still come in excellent quality and at a very good price. For example, Stellit 6 alloy. We tried to order them a similar alloy.
                    Also Stellit, but according to GOST - В3К
                    The difference is a couple of percent in chemistry.
                    Alas...
                    and when I discuss with their engineer
                    Special alloy part drawing
                    I get the question - what is h16, H16? etc. (For non-mechanics - designation of standard allowances / tolerances for accuracy)
                    Like this! Accordingly, if you want to order something - be nice, teach the Chinese comrades, and then 10 again check the process and be sure! Ready to ship products. And not because they are cheating (although there is one) - they simply do not know how!
                    But it will be super polished! Externally - well, just like new)))

      it should, of course, only it doesn’t form. Pin_dosnia, too, everyone wants their real engine to fly to the ISS, but they can’t do anything, and they still have engines from von Braun and they can think of nothing else except the Holivut f1. In short, if in the near future will again be the purchase of our AL-31, it will be clear what these stories are worth.

      To have a school, we need our own developments. The Chinese mentality is designed to follow instructions and rules, to elementary cramming, where there is no place for creativity. As soon as the opportunity for copying ends, they simply stop, because they can create nothing purely Chinese.

    Well, if in essence, then the eastern neighbors do not stand still and who knows how many years later they will catch up with our current school of engine building .... We need to keep a distance and conduct our developments.

If you haven’t managed to sell it to China yet, then the states will not allow it and simply fall apart. Russia can offer at least half the budget, nothing will break off for us.

    China announced a “breakthrough” in creating engines for the new generation of J-20 fighters.

    I’m just sure that the military development of Russia shouldn’t just become the property of anyone. As for this breakthrough, this is another step towards weakening the PLA's dependence on Russian production. Of course, a question arose (not from scratch and not from the kondachka):
    WHAT WILL HAPPEN TO THE RUSSIAN-CHINESE RELATIONS WHEN THE ONLY HYDROCARBON DEPENDENCE ON THE FORGOTTEN PEOPLE WILL REMAIN?
    belay
    The life of generations of Soviet people is simply thrown into the furnace so that someone on this Earth becomes warmer, and we are surprised every week either by the scale of theft, or by blatant cynicism and cruelty, and we want new Gagarins, Kalashnikovs, Tupolevs, Korolevs ... So that in life there was joy, not a bitter sediment.

      While a class society is being rapidly built in the country, only the appearance of matvyonoks, Rogozins and patrushevs is possible. And these are accustomed only to the "royal" ways, which, as is known since ancient times, are not in science. But any development contrary to historical logic is doomed to failure, and this abomination will end. It is a pity only the loss of three decades and millions of compatriots who could not stand such humiliation.

    A whistle is an artistic ... Chinese ... GTE blade technology for 5 generation engines DEMANDS equipment that is NOT being sold to China. Neither we, nor Americans, nor Germans. And without these VACUUM installations and technology for applying heat-resistant and thermo-barrier layers, the lifetime of turbine blades at high temperatures drops sharply. The result is an engine resource! And dozens of times ... And technology, technology ...

        Chinese intelligence services are actively using in their work citizens traveling to the United States for permanent residence, students to study and businessmen. This tactic was called "thousands of grains of sand." She was adopted from the Japanese. In the 50 years, every Japanese from a foreign tourist trip brought photographs of cars or household appliances, up to the design of toilets. This made it possible to quickly restore the country's economy, which suffered during the war.

        Chinese intelligence agencies are tracking citizens traveling abroad, whether they are tourists, businessmen, or students. Only the latter annually there are more than 100 thousand. They are interviewed, both before departure and upon return. An amateur spy who brings valuable information receives a number of privileges.
        Chinese intelligence in the United States is not only interested in military secrets. A certain Piny Kashu sent to China technology for the production of organic pest control products. It was a trade secret and was valued at no less than 350 million dollars. This technology can be used to produce chemical weapons.

              Better yet, enter the school curriculum, but this is unrealistic. "Six secret teachings. Instructions for the effective overthrow of the dynasty."

              I accidentally stumbled upon two clips from Poltoranin. Look - you will not regret it:

    In the photo there are strange nozzle flaps with UVT, huge massive in comparison with ours. Is this their know-how, or could not make a copy? no

    Yes, everyone knows how China is making all its “breakthroughs”, most of the technologies of Soviet and Russian. A huge amount of resources has been thrown into the processing of “borrowed” technologies, but the output is still worse quality.

    If this is not a stuffing, then the level of Chinese engine building is so-so.

    Thrust WS-15 14,5 kgf - and take-off weight J20, therefore, 30 kg? laughing

      Well, taking off weight through the latest technology is also a breakthrough laughing

    Well, J-20 is equipped with variations of WS-10, and these words about the breakthrough are a means of propaganda and rather an expression of dissatisfaction with the lack of a similar one where they could buy it

    WS-15 is the P-79 that the Chinese received from Russia. For 20 years, they couldn’t do anything sensible. Their entire breakthrough is the nozzle from Salyut, developed by Esche under Eliseev. Problems with the degree of increase in pressure, problems with the transition from idle to full-speed mode, problems of engine stability in a wide range of heights and speeds.

    Well, if the Chinese have solved the riddle of the 1984 of the year, then here’s the next riddle for them: Create an afterburner engine for the 5 generation aircraft. For, by the joy of the Chinese, it is still possible to understand that they have finally come nearer to 4. Whatever they say about their next team hodgepodge J-20.

    China announced a “breakthrough” in creating an engine for the J-20 fighter
    I would not want to quote Zadorny, but it begs itself .. Well, stupid ... Even in the age of industrialization, in the USA there weren’t so many resources, technologies and dough concentrated in one place and at the same time .. Amazing .. Like the Chinese they still haven’t sent a manned expedition to Jupiter ..

    According to the plan, WS-15 turbojet engines should provide thrust at the level of 14,5 kgf

    The first time is an accident!
    AL-31F (its afterburner traction - 12,5 kgf).

    The second is a coincidence!

    I know how readers relate to NI, and specifically to Dave Majumdar, there is a lot of skepticism among the audience, but I read his articles calmly, because There are dozens of magazines like NI in the US and there are plenty to choose from and compare. So, in September, NI published his article called
    “The Chinese J-20 Stealth Fighter has a fatal error (which may be fixed soon)
    https://nationalinterest.org/blog/buzz/chinas-j-20-stealth-fighter-has-fatal-flaw-might-soon-be-fixed-30912
    “The WS-15 is expected to be ready for widespread installation on the J-20 by the end of this year,” said a Chinese military source, South China Morning Post. The same source noted that the WS-15 still has “minor problems” that must be resolved after more intensive engine operation on the plane.
    “Sources disagree with the exact WS-15 traction rating, with ratings ranging from a minimum of 30 000 pounds of afterburning to a figure in 44 000 pounds of afterburning. It is known that the WS-15 prototype, which has been developed since the 1990's, created thrust in 36 000 pounds, and at that time forecasts predicted that the operational version of the engine would produce thrust in 40 340 pounds - and this would have three-dimensional vector thrust.
    “The South China Morning Post reports that the traction-to-weight ratio of WS-15 is greater than ten to one, which, if true, is comparable to the F119 and F135 Pratt & Whitney that power the Lockheed Martin F-22. Raptor and F-35 Joint Strike Fighter respectively. However, while the Chinese engine can produce traction levels comparable to those of American engines, the WS-15 does not reach the longevity of less than half the time to overhaul.
    “However, the issue of WS-15 remains unresolved. While the Chinese have demonstrated the ability to create sophisticated jet engines with single-crystal turbine blades under laboratory conditions, Beijing's efforts to mass-produce reliable jet engines are extremely unsuccessful. WS-15 had a particularly difficult pregnancy, and it remains to be seen how well the engine works when flight tests begin in earnest.
    “All the Chinese J-20 observed in this way were equipped with either the Russian AL-31FN salute or the WS-10B. “The use of WS-10B engines is only a temporary and expedient stage in the development of the J-20 engine ... in the future, the aircraft may use another new engine, a version of WS-10 with improved engine performance (IPE), WS-10 IPE, while the development of WS-15 will not be successful, ”a Chinese military source told SCMP earlier this year. “Several times it’s so awkward to change engines for such an important aviation project ... only because of the unreliability of existing WS-15 engines. This is a long-standing main problem among domestic aircraft. ”

        In fact, I always apologize for my comment on the Google translation - I do not know the correct terminology, and there is no time for editing. Thank you very much, but in the future the translations will be the same, but with my apology in the beginning.

    "On Chinese TV, it is stated that during the tests the engine of local manufacturers WS-15 (Turbofan)" surpassed the AL-31F in a number of key parameters. "

    One of them I already know, it is cheaper.

    After reviewing the chronology of the creation of military equipment in China, we can confidently say that the "under heaven" did nothing of its own, a solid copy-paste. I’m Tulyak myself, my father worked all his life as an engineer at TOZ and we often talked with him about the world war industry. So, he constantly said that 90% of success is metals (alloys). You can copy anything . Literally everything!, But it won’t be driving or flying for one simple reason: the lack of the necessary alloys. That is why we easily sell them small (relatively of course) lots of weapons without fear of copying. We know that they won’t do anything good anyway .
