China disagrees with Russia's demand for AL-31F engines


China is refusing to use Russian AL-31F engines in future J-20 stealth fighters, preferring a domestically produced alternative. The National Interest magazine writes about why the Chinese decided to abandon the AL-31F and how they will replace the Russian development.


The South China Morning Post previously reported that the Chinese fifth-generation J-20 stealth fighter would no longer be powered by the AL-31F. The decision is obviously connected with the insistence of the Russian side on linking future sales of AL-31F engines with further purchases of Su-35.

The PRC cannot rely on the Russian engine, as Moscow has asked Beijing to buy more Su-35 fighters in exchange for supplying additional batches of AL-31F engines.

An inside source told the Morning Post.

The PLA Air Force was the first foreign customer to import the Su-35, one of the most advanced Russian fighters, under a 2015 contract for the purchase of 24 aircraft. But the Chinese army is no longer interested in purchasing additional Su-35s. At the same time, the Morning Post source claims that the Chinese aircraft industry has achieved similar, if not superior, capabilities of the J-16 strike fighter (a copy of the Su-30).

With both sides at an impasse over further sales of the AL-31F, the Chinese are switching to the WS-10C, an improved version of the WS-10 turbojet engine. An insider's source confirmed to the Chinese newspaper that future J-20 models will be equipped with the WS-10C, which, in their opinion, will be similar in technical characteristics to the AL-31F.

As the source admits, both the AL-31F and WS-10C are only temporary solutions. It was planned that the J-20 will go into production with the new WS-15 engine, but the aircraft was quickly adopted by the AL-31F against the backdrop of a sharp deterioration in relations between the United States and China under Donald Trump. Developed since 2005, the WS-15 will enable the J-20 to maintain supersonic flight without the use of afterburners.

    Well, to hell with them, let them themselves now think how to get out of this situation, the Chinese engines have always been an "Achilles heel" in aviation, persuading them to buy our engines and make concessions to the Chinese, accepting their conditions, is all the more worthless, you can't constantly dance to someone else's tune.

    Why are we trying to replace imports with our own, while the Chinese can't? They are doing everything right.

      They try to do it but it doesn't work out very well. It is not enough just to copy 1: 1 dviglo, here you need knowledge in materials science, etc. and with this the Chinese have a hat.

    I read the comments to the article and got completely confused.
    1. Armenia recognized Nagorno-Karabakh as a part of Azerbaijan.
    2. The Armenian army did not fight for NK. The criticism of the Armenian S-300s, which could not shoot down anything in NK, is especially pinning !! ??
    3. The Armenian authorities prevented the transfer of volunteers to NK !!
    But at the same time Russia had to commit an act of aggression against the territory of sovereign Azerbaijan ???? The liberals from "Echo of Moscow" dreamed about this especially a lot.

    Well, the Chinese are very good cheek blowers. They know how to bluff, I must admit. The main thing is that we have our own AL-31Fs, and what the Chinese are going to do with the WS-15 is their own headache. The non-stop sputtering of American technologies is fading away, revolutionary technical and technological solutions are not a copy-paste of yesterday, here even Trump, even Biden, none of them are happy about Chinese industrial espionage on a solid state basis.

    So this is great, they will do more for their own Air Force, maybe they will finally bring "unparalleled" at last.

    The Chinese will not go anywhere; China is still unable to produce normal blades for turbines.

    It was immediately clear that the Chinese wanted to get only Su-35 technology and Russia initially had to insist on a minimum purchase lot of 50 units.
    They chased after momentary profit and got, as always, a "zero" ...

    It's just that the Chinese wanted to cheat us. Buy engines and put ON YOUR OWN. Ours said, only with the SU-35. That's the whole bazaar. China can't make engines!

    Just like a recurring bad dream: first, "out of the kindness of our soul," we sell China a small batch of something high-tech, and then they are - what a surprise! - they copy everything and refuse further large-scale purchases. The life of the Nullified does not teach anything
