Media: Russians have found a tricky way to protect their engines from copying


Russian designers have developed a non-standard way to protect aircraft jet engines from copying by specialists from other countries and, above all, from China. This is reported by the Vietnamese edition of Soha (not to be confused with the Chinese Sohu).


China has not yet learned how to create high-quality engines for aircraft, which could compete on equal terms with American or Russian products. Therefore, the PRC authorities are buying foreign combat aircraft, including Russian ones. However, Russia has come up with a tricky way to protect its intellectual property from unwanted copying.

First of all, the Russian authorities do not sell engines separately - it is proposed to purchase a military machinery fully:

China wanted to buy the latest aircraft engines AL-41F1S. However, in Moscow they replied that they would only be sold together with Su-35 fighters

- noted in Soha.

The difficulty for those who want to "repeat" the technological success of Russia is that it is very difficult to get to the secrets of Russian aircraft engines without damaging the power units themselves. In addition, it is very difficult to completely copy a jet engine and takes an extremely long time, so creating a high-quality copy is not possible in principle.

China seeks to reduce its dependence on foreign technology by investing heavily in new developments. Beijing is also trying to use groundwork in civil aviation for its implementation in the military industry.

    - And this is the whole "tricky way" ??? - And the fact that China will have new Su-35s, of which there is still not enough in Russia itself ... - is that too, or something ... - the next "tricky way" ???

      This is not "CunningPlanPutin", but ordinary commerce practiced by everyone. How many engines can I buy for the price of one aircraft and how many planes for the price of one engine? Moreover, to copy, you need to have a very specific amount of technology and manufacturing standards. Why, in your opinion, no one can repeat the RD-180 rocket engine, although specialists know everything about it to the screw? Do you think the Chinese are not exploring our technology?

      Why write something in which you have no idea at all. Study the subject at least in Yandex search, then all the questions themselves will disappear for no need.

      These Su-35s are not the same as in Russia itself. Therefore, let them have. At least, the staff will earn money. And keep your knowledge.

    Copying military (and many other) products is complicated by the difference in production technologies. Other standards (GOSTs), other compositions of materials. Theoretically, it is possible to repeat this, of course, but in order to put it on the stream, it is necessary to copy all the technological nuances on an industrial scale.

      Not necessary. Remember the story of the Tu-4? But for this we need our own engineering school, at least not inferior to the school that created the model for copying. The Chinese have a Soviet school, but while the Chinese were flirting with the United States (from 85-98), our school has gone far ahead, despite the terrible situation in the country.

    Of course, the designers are making efforts to protect against copying: alloys, creation and processing technologies, etc. The article is about nothing, just a set of common words.

      Looks like you are far behind if you don’t know that the whole World uses our technologies! For example, all planes fly on Russian spare parts and many others.

    Once the USSR had to copy the American B-29, made the TU-4, for this we had to build a whole series of new plants, which we did not even have a trace, because the Americans did not give us their machines and materials for this aircraft. Likewise, China needs to, or another country will have to do it all from scratch, and then in the copy of the B-29 on the TU-4 the motors were of their own production, they were not copied. It is also possible for the Chinese to copy the plane, but with engines it is very difficult to do it. In fact, you will have to develop it yourself anew. As we know, they cannot develop it with a new one, they themselves will make such an aircraft, and of course, it may even be better than ours, and, of course, we only want to buy an engine for it, just as the Americans buy RD-180 for their missiles. And something cannot do it in any way, while they make a rocket to it easily.

      If it’s quite simple, then you can take a closer look at the Institute of Metals and Alloys: the most interesting, you know, educational institution from the introduction onwards is the school, and not the only one, thank God.

    I do not understand, the USSR has always copied American and English engines, the same AL-41 on the Su-27 - Su-35, why the Chinese can not? They have been testing their engine of the same class for a long time, however, they did not copy the AL-41, they took the CFM56 gas generator as a basis. About 3 years ago, they received the required performance characteristics with a meager resource (at the level of products on the MiG-23), now they are finishing, I think, they will finish. Their main problem is heat-resistant materials, but the Chinese have solved more complex problems, they will solve this one as well.

      I didn’t understand - we still cannot make alloys from which the Volkhov-Kommunar rescue ship was built, built in Tsarist times ... try to make it yourself. Although science knows everything about metal.

      Bukovka L in AL-41, means Lyulka - and this is the name of such a Soviet designer, the genius of heat engineering, who invented a dual-circuit jet engine. The most powerful rocket engine, the RD-171, whose two-chamber half is the RD-180, is still bought by the States and cannot build something like that, not to mention copying it too.

      Are you sure that the AL-41? On the Su-27. Maybe all the same AL-31? That is, you blame our designer, who had a copyright certificate for this engine, that he copied it? There is nothing wrong with that, but you don’t have to row everything on the Western mind. Ours and well done themselves. You still remember about the Volga, a very interesting story.

    To copy such a product, the original is very small! We need all the basic routings, at least. And this is a military secret. And even in China, completely different GOSTs and production technologies, but a lot of tenacity, will make their own engine. With time.

    The mentality of Chinese engineers and technologies is focused on the manufacture of parts, products, equipment for a short-term operation - so that equipment - machines quickly fail and the client - the country buys again and again ...
    This mentality of traders played a cruel joke in the development of industry ... and the production of goods ....
    Just remember the period when industrialization began.
    From 30-40-50-60-70 GOSTs, SNiPs, ENiRs, SanPiNs ...

    Actually, sohu is a Chinese news agency, as you know. I think the article is not relevant.
    2. No one will import precisely those engines that they produce for themselves.
    3. Think people! Do not turn into Pavlov’s reflex.

    China wanted to buy the latest aircraft engines AL-41F1S. However, in Moscow they replied that they would only be sold together with Su-35 fighters

    You see what happens when, instead of knitting socks, a woman climbs into military equipment. I asked you to do something that is inherent in you.
    Supply of the product as a whole.
    This probably brings more dough. Or do you disagree with this? Further. The delivery of an airplane with an EXPORT design control program for the main parameters makes the product not so ...., to put it mildly ..... The most important thing is not the engine iron. It is copied by competent engineers quite simply. The main thing is the finest control not only of the engine, but also of the machine as a whole.
    The engines of the tank and Formula 1 have the same power. The difference is in boost modes. Extremely forcing obliges to adjust the parameters "on the razor's edge." Micron to the right - micron to the left .... I think people involved in this technique have the mind (unlike some here) to sell what they can not compete with ours, but are higher than what the buyers themselves do in order to maintain they have an interest.
    You can more easily sell military equipment to those who will not turn this weapon against you, well, at least fifty years. And he will not transfer it to third parties. A military airplane, made for yourself, will never return the budget spent. An airplane, exactly the same, sold for export, returns, and allows people like you to have pensions, health care, and so on, provided by the state. Although I would deprive such stupid of all this. Until they understand that they have been stupid.
