China named "main weak link" of J-20 fighters after analysis of night flights

26

The Chinese military command analyzed a series of flights of the latest J-20 fighters, during which information was collected on the specific flight characteristics of these combat aircraft.


One of the components was associated with the performance of night flights by J-20 fighters, in which aircraft, positioned in China as "stealth", had to approach the target as close as possible for a conditional strike and at the same time remain out of the reach of ground air defense systems.

As noted in the Chinese media, citing sources in the PLA Air Force, during such flights, the "main weak link" of the fifth generation fighters was revealed. Engines are called this "major weak link" in China. It is said that aircraft with Russian-made Al-31FM2 engines "experienced difficulties with stealth". These engines are reported to have “had a significant impact on maneuverability and stealth performance, with stealth performance especially degrading at supersonic speeds.

The Chinese press notes that the J-20, during night flights, was determined by ground-based air defense systems at the time of the supersonic flight. At the same time, it is not reported whether the targets that were originally mentioned were "conditionally hit".

In addition, it is noted that the military command expects that the Chinese-made WS-15 engines will help solve the problem with maneuverability and stealth in various flight options of the fifth generation J-20 fighter.

    And here Russia is to blame, but they themselves have little to do, or there is only enough Xerorks knowledge)))

      They don't have their own engines, and the Russians are bad?


      Nah ... In the daytime they had everything normal with stealth yes , but at night ... At night the problems started what .

      Did you have a dream?

        What surprised you so much? During the day, any plane can be seen from afar in the reflection from the sun and on the contrail.
        All checks, of course, at night.
        Check for IR signature at night.

      So before that, the Chinese were galloping, they say, they already put their own tons of 18 tons each. Well, in 15 years, maybe they will bring it to mind.

      So buy from Americans, Europeans.

      They will not sell

    It should be clarified: did the air defense detect the J-20 at night by optical instruments or by radar?
    On which supersonic airplanes became more noticeable - afterburner or non-afterburner?
    If the aircraft is visually more noticeable on the afterburner, it's okay.
    Stealths should not approach air defense at supersonic speed - stealth is more important than speed.

      The Chinese is heavy and the AL-31 is unlikely to be able to master supersonic flight without afterburner.

      The Hindus said that the Chinese J-20 was clearly visible on the Su-30 radars. True, the range with which it becomes noticeable was not indicated.

        The Hindus noticed them over Tibet. The Chinese were over their territory.
        And not in combat operations stealths tend to fly with lenses,
        dramatically increasing radio signature. Therefore, it is not clear if there is
        value in messages from Indians.

          The Americans have it. But whether the Chinese bother with this, the question is.

            The Chinese are attentive copiers.
            Here is the Luneberg lens on their (still prototype) J-20.
            It is exactly the same shape (yellow cylinder)
            and in the same place as the F-22

              smile I don’t argue with that. They can copy. But did they copy the lens, or just the yellow cylinder, in which it should be located?

                Don't think their engineers are stupid.
                They, I am sure, perfectly guessed that he was himself

                  I did not say that.
                  But I admit that this is the EPR of an aircraft with a lens, but in fact this is its (J-20) true EPR.

                    recourse uh ...
                    In the frontal plane the J-20 is made very stealthy, faceted,
                    no roundness, no right angles.
                    From below, its radio signature will "spoil" the front horizontal tail.
                    Everything else in the fuselage, keels, wings is done right
                    in terms of stealth. The assembly is neat, the rivets do not stick out.
                    Most American experts believe that the J-20 "worked out."

        - And they did not indicate whether the lens block of Luneberg was on it at that time, or was removed ... laughing lol

      It would be necessary to clarify:

      Yes, they would go to the forest. There is no need to clarify anything. In the networks and in the media, this nonsense from the "plow" is apparently invisible. Let's also discuss here how crazy this nonsense is and what caused it. For such, it's time to post a poster:

    Notice! Our Chinese "partners", this is not the first time in the world press, they have been biting Russian weapons, which they buy from Russia with great desire and passion, especially new and advanced ones, first of all, to copy !!! This is mean! But money doesn't smell! Throwing mud at our weapons, they push their shamefully copied, but in their opinion the best, in relation to the Russian! It is necessary to draw conclusions, and not play in diplomacy, as with other countries! You have to be tougher, tougher and put them in their place!

    Of course, WS-15 engines will solve these problems. No engine - no problem! laughing
