"One of the obstacles to stealth of the J-20 fighters are the Russian Al-31F engines" - Indian expert

39

Indian media publishes materials that examine the degree of threat from the Chinese fifth generation J-20 fighters. One of the Indian experts looking at this topic is Srinjoy Choudhury.


Traditionally for many Indian experts - without providing specific technical and technological justifications (and this is what Chinese experts are guilty of) - Chowdhury writes that the PLA J-20 fighters “do not have a high enough level of stealth to allow them to remain unnoticed by ground-based air defense radars. and aviation India. "

Indian expert:

It may not turn out to be at all the stealth in its level, which should be characterized by modern requirements. The J-20's stealth deficiencies will allow Indian air defense to catch their breath - it is quite easy to track Chinese aircraft in the air.

The Indian press indicates that the PLA Air Force J-20 fighters have already twice been detected by the radars of the Su-30MKI aircraft of the Indian Air Force.

Srinjoy Chowdhury:

One of the obstacles to the J-20's stealth is the Russian Al-31F engines.

It is added that during the afterburner the aircraft "consumes a huge amount of fuel, which reduces its range, while making it visible to radars."

As a result, the Indian observer sums up:

The J-20 is a challenge from the PLA for the Rafale fighters acquired by the Indian Air Force, but it has drawbacks that the Indian air defense system can exploit.

      Uh-huh, these are the Indian experts who armed the army with three rifle models, unfinished a flawed tank, abandoned work on the project of their own aircraft and rent our nuclear submarines, dirtyly allowing the Americans and not observing secrecy? Gygygygygiants of advanced technical thought are unthinkable.

        calmly, there conditionally the true kshatriyas are engaged in war.
        Merchants / Vaishnavas / only make deals. Satisfy the needs of high Kshatriyas. India uses a unique paradigm. India can buy weapons and technology from 2 centers at once. The Western world or Russia can provide TECHNOLOGY. This is such a complicated thing that you cannot explain. cupola...

      Yes sir! Leading experts wink

      The J-20 is a challenge from the PLA for Rafale fighters acquired by the Indian Air Force, but it has drawbacks that the Indian air defense system can exploit.


      But for some reason, for Rafaley, but they were observed on the Su-30MKI radars laughing But Rafali was not seen, they were standing somewhere in hangars ...

      Well, the flaws will be exploited by the Russian-made air defense system bully

      The article as a whole reads: do not buy Russian engines, they are bad fool but to myself: let the Russians sell us better wink

    in afterburner the aircraft "consumes a huge amount of fuel, which reduces its range, while making it visible to radars"
    And the Indian "expert" will not tell you which aircraft engine does not consume more fuel on afterburner? It is clear that the long-standing territorial "friendship" with China requires at least injections, but why focus on Russian engines. And when will the Indians fly on their planes with their engines?

      The Indians apparently assume that with the Al-31F, the J-20 cannot reach supersonic speed without afterburner, which makes it more noticeable.

    Oh, those Indian experts! Don't they like the engine? But where did the myth that the J 20 is a fifth generation fighter come from? IMHO, this is a hybrid. Elephant with a teapot. What kind of afterburner supersonic is there? There and afterburner not everything is clear ... So in this they are right. China is so ... mysterious.
    And let the Indians make something for themselves. High tech. 5th generation engine type. The French have promised them something ... Wait.

      The radars seem to detect fuel consumption.

      Apparently on their radar screens readings of flow meters are highlighted.laughing

      And to explain, and even plausible, it’s necessary to understand the topic at least a little.

    Two tribes came from ancient India to the West: the Gypsies and the Jews. The Jews "dwelt", although they had "wandered in the wilderness" for a long time before. and their fellow Gypsies, still "wander" around the world.
    And modern indigenous Indians, weeping, give their last rupees
    to defend against China, regretting that then more Jews were expelled than Roma. Summary: today to have serious business relations with India, what to play preference with "scammer".

    the fact that in terms of EPR efficiency, according to the Americans themselves, the f-35 is about 22-1.5 times worse than the f-2, just because it has 1, and not two, exactly the same engines. This is the logic. The more engines on the plane, the more invisible it is. And the J-20 has a problem with stealth because it had to be equipped with not 2, but 10 al-31F engines. Then not a single bastard would have detected it and the afterburner would not have to be turned on.

    I would draw your attention to one point: merchants are Vaishyas, and Vaishnavas are Vishnu worshipers! That is, a Vaishnava can be a representative of any caste, but usually they are brahmanas - Vishnu worship has traditionally high standards.
