In China, spoke about the emergence of a new version of the fifth generation fighter J-20A

In the Chinese edition of Sina, it is reported that the developers and creators of the new generation J-20 fighter have recently been finalizing the engine nozzle. As it turns out, the aircraft had problems with a controlled thrust vector when flying at supersonic speeds. In other words, the pilots did not have the opportunity to perform truly complex maneuvers.


This explains the fact that even during demonstrations on airplanes that have already entered the arsenal of the PLA Air Force, Chinese pilots showed aerobatics, which did not cause frank delight. These figures, to put it mildly, are not quite characteristic of what is today designated as a new generation fighter. In China, they tried to claim that the whole problem was “in Russian engines”. However, when they began to equip the J-20 with their own power plants, the problem did not disappear.

Now, as claimed, the controllability of the aircraft in the super-maneuverability mode has become much better. At the same time, they are talking about the appearance of a modernized version of the new generation Chinese fighter. This is the J-20A, which differs from the basic version of the J-20 engine WS-15 with a design change nozzle.

The WS-15 is a turbojet aircraft engine that claims to provide a thrust of 14,5 tons at a turbine temperature of 1,4 thousand degrees Celsius.

Earlier it was reported that the engines manufactured for fighters in China have a problem consisting in a sharp decrease in thrust when the turbine exits to operating (temperature) parameters. The problem, as Chinese experts now claim, has been resolved through the "use of new alloys." What specific alloys are in question have not yet been reported.

    It turns out that if he was (in the Chinese version) the best in the world before, now it turns out that he became the best in the galaxy. laughing But it seems to me that for some dancers, constantly, something is interfering. We will wait for the next news, about the next improvement of the J-20A, and that it will be the best in the universe.

      Unfortunately, whatever it may be, but the series will be big. That is, the threat exists. Sometimes our cars were not so perfect, including the same engine. So let the Chinese be proud of their successes, and we must seek resources to strengthen our military power. In terms of defense spending, they are significantly ahead of us, and unfortunately no changes are expected here.

        They are ahead of us somewhere 3 times, but, at the same time, are spent on the fleet. The most expensive pleasure. By land approximately in parity,

          They can put under the arms of men more than our population, together with pensioners, children and women. They invested in factories, roads, infrastructure and people - this is the same defense industry. Not the official budget figures. In the USSR, I also remember 18 billion rubles, with more than 100 billion in the United States. So "parity" with China (especially on that theater of operations) without our strategic nuclear forces looks ridiculous. Moreover, the fighters are stubborn (and now also with intelligent commanders). Don't believe me? Look who really pulled out the Korean War.

            Alex, I agree with you. And for the war in Korea, too. I think that China is the most prepared country for the Third World. Discipline, army, underground shelters. The reserve of the Great Wall exists.

    And why do they need UVT at supersonic speeds? Does it smack the lantern?

      I’m also trying to comprehend this issue, turning the nozzle seems not to be a problem, but to make a maneuver .... Maybe there is a reverse needed to carry out an effective maneuver in these modes. (joke) hi

    The Chinese will bring their misunderstanding with wings to mind much more than their Yankees f35! You can’t go far on a treated horse! Without its engines, the Chinese letak will never become a full-fledged combat aircraft, and the lack of an engine school for military aviation, and replacing it with copy-paste will not give the Chinese the most important technology.

    Do the Chinese have rotary nozzles on their engines? What for? They have the same "duck" scheme - maneuverability and so sufficient.

      For maneuverability, one duck is not enough. Need more thrust-to-weight ratio and the load on the wing.
      Of the listed Chinese Pipilats has only a duck.
      Duck alone does not solve.
      On the plane it is clear that with maneuverability he has, like a su-24 or worse .. IMHO

    recently engaged in the refinement of the engine nozzle. As it turns out, the aircraft had problems with a controlled thrust vector when flying at supersonic speeds.

    The very layout of the aircraft does not predispose to over-maneuverability. It is doubtful that the engine nozzles will radically change the situation.
    Chinese pilots showed aerobatics, which did not cause frank delight. These figures, to put it mildly, are not quite characteristic of what is today designated as a new generation fighter.

    That is yes. So it’s not in vain in the world that only as long as one country has built a 5-generation fighter, and it has so many minuses that it never became the basis of the air force. And the Chinese are only at the beginning of their air travel.

    So I look at these Chinese planes and think the following:
    PGO (front horizontal tail) in flight deviates very much. This should have a catastrophic effect on the EPR. How does this happen on the Su-30MK, etc., in comparison with the usual modifications of the Su-27.
    And I do not believe in the invisibility of the Chinese aircraft. On American and ours there is a deflected toe of a wing of a large area. But they have normal plumage.
    Something is wrong here. They ripped off the idea of ​​PGO from us. But the outcome of this idea .... is still unknown and somehow dubious.

      So the Chinese do not believe. Patriots are just ... obliges to believe.

      The rear horizontal plumage gives no less flare on the radar than the front. They have no back plumage. Flare can be given simply by the wing of an airplane if it is in the right angle, and flare from a conventional wing will be the strongest.

      etc. compared to conventional modifications of the Su-27

      Do not tell me what the usual SU-27 EPR? Somewhere 12-15 meters, and this is without canopies. In secret, the SU-30, with PGO less.

        I will not say. The memory is not rubber. My aviation is a specialty, not a hobby. I can’t drag everything into my head. EPR Su-30 in flight increases sharply. PGO spinning strongly.

        And why should the EPR of the Su-30 with PGO have to be less? A bullet was added there and PGO was attached to this place. This is the whole change in aircraft theory. We attached a refueling bar. The contours in this case have not changed. Replacing the engine is just a nozzle sticking out. Well, still for use in India, finally, the design of the fins was changed. From the large - everything.

            I think that you cannot believe any of these numbers. That's all. My information is all from the same place. From the end of the 90s. From insider sources, so to speak. Yes, in general, the way it should be. The specific figure, I think, is not important.

    Remember the fairy tale about the king, two crooks sewed him a suit, but not some sort of one, but invisible. He walks through his kingdom, I have not seen such boasting to everyone, the dress is royal, but it is not visible. The citizens praise, rejoice because if you tell the truth, you will lose your head. And only a little boy said "and the king is naked" So the Chinese, sawing their budget, praising their technique

    and they’re maneuvering at the top

    UHT at almost maximum thrust or afterburner?
