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

25 May 2020 26

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 are not many in Russia itself ... - this is also, or what ... - another "clever way" ???

  This is not "Putin's TrickyPlan", but ordinary commerce, practiced by everyone. How many engines can you buy for the price of one aircraft and how many aircraft can you buy for the price of one engine? Moreover, in order to copy, you need to have a very specific amount of technologies and manufacturing standards. Why, in your opinion, no one can repeat the RD-180 rocket engine, although the specialists know everything about it to the cog? Do you think that the Chinese do not research 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.

This very "cunning" method has been used since colonial times, if not earlier.
Common sense is called.

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 it was necessary to build a series of new plants, which we didn’t have, because the Americans did not give us their machines and materials for this aircraft. China also 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. The Chinese can still copy an airplane, but with engines it is very difficult to do. In fact, you have to develop it yourself in a new way. As we know, they cannot develop it in a new way, they themselves will do such a plane, and of course, it may even be better than ours and, of course, I want to buy only the engine for it, as the Americans buy RD-180 for their missiles. And there is nothing they can do to it, 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 did not understand - we still can’t make the alloys from which the Volkhov-Kommunar rescue ship was built, built in Tsarist time ...... 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 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 years GOSTs, SNiPs, ENiRs, SanPiNy ...

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.

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.
Tank and Formula 1 engines have the same power. The difference is in the boost modes. Extremely forcing obliges to adjust the parameters "on the razor blade". Micron to the right - micron to the left .... I think the people involved in this technique have enough sense (unlike some here present) to sell what cannot compete with ours, but are above what the buyers themselves do in order to maintain they have interests.
You can more easily sell military equipment to those who will not turn this weapon against you, well, at least fifty years. And he won’t pass it to third parties. A self-made military airplane will never return to the budget. 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 stupid such deprived of all this. Until they understand that they have frozen stupidity.
