Chapter 2473

The research and development of the engine must be earlier than that of the whole machine. Only in the form of research and development such as Han country, there is an engine project only when there is an aircraft project, resulting in the engine always being dragged down.

The Su-27 fighter of Xiong Guo has not made its first flight. The prototype still uses the al21 turbojet engine. The al31 turbofan engine has not come out yet. The liulika Design Bureau has started the research and development of a new generation of engine, which was only in 1981.

At that time, the design index of this engine was 18 to 20 tons of thrust. It was called "product 20" in the design bureau and AL-41F for the outside world. If you want to become a new engine, you must have a new model. It widely uses new structural materials - ceramics, cermet and more advanced core engine, changes cycle parameters, uses high load turbine and compressor blades, and makes the thrust weight ratio of this engine reach 11. Of course, this is the standard of Xiong Guo. According to the international general standard, The thrust weight ratio has also reached 10, which will be a cross era engine.

At that time, r179-300 engine was considered as an alternative to AL-41F. This is a further development of r-79v-300 engine. The thrust has reached the order of 20 tons, which is not small. However, after the review of relevant departments, it is considered that the performance of r179-300 engine can not be compared with al41f engine at all.

In fact, the test of this engine was started in 1988. The first batch of aircraft was installed on the aircraft for test. However, for an engine, this test is bound to be long.

Like our own turbofan 61, it took one year to assemble, and then more than ten years to test. Finally, if it failed to meet the requirements, it had to stop research and development.

The same is true of this engine. When it steadily entered the R & D sequence, Xiong Guo disappeared. Without a strong source of funds, the engine did not develop.

Later, the liulika Design Bureau used some achievements of this technology to develop a new F117 engine. In fact, it applied some al41f technology on the basis of the original al31f. Even so, it was underestimated by the Xiong people. They thought it was so powerful that it was not exported to the Han country.

Now, when it comes to this kind of engine, dongdukov certainly looks envious. Although the thrust of the engine is similar, the push weight ratio of others is high. Under the same thrust, the weight of others is almost half that of their own side. In this way, at least one ton of structural weight can be saved, and these weights will become fuel or mounting, So that the performance of the aircraft can be greatly improved.

Unfortunately, they can't get that kind of engine.

"Now, Jacques 141 is about to be developed. This aircraft will certainly become the most advanced fighter of the Xiong Navy. As an advanced aircraft, shouldn't it have the most advanced engine?" Qin Guan said: "I think it's unfair to you!"

"Yes, it's time to report to the senior management of Xiong Guo and ask them for the engine!" even President Gu fooled aside.

Twenty of these engines, the original prototypes, have been built. Some of them are used for testing, and some have been installed in project 1.42 of MgO Yang Design Bureau. They can all use them. Why can't the aircraft of yaklev design bureau be used? Their plane is also cross era!

As long as the yaklev design bureau wants it, you can get all the parameters. If this engine is really so powerful, it is also good to be used in your stealth VTOL fighter. At least in the design, you can take a lot of technical indicators into account.

Of course, President Gu knows that this is beneficial.

In fact, Qin Guan mainly prepared for the J-15. Of course, this is just easy. After all, this engine has not been successfully developed. Even if his own side has obtained it, it is at most a prototype, and there are still many problems to be solved. Although r79 has many problems, it can run stably after all, otherwise Lu will not like it.

Qin Guan's greatest intention is that the drunken man's intention is not wine. He values the designers. When he studied the Tenth Five-Year Plan of turbofan, he had his own systematic help, but he still spent a lot of twists and turns because of the lack of talents.

When the state of Xiong collapsed, Qin Guan wanted to dig up a large number of talents from the state of Xiong. If they should come, they will come, so that the state of Han can quickly become a powerful scientific research country. Anyway, for those old maozi, the state of Xiong has no nostalgia.

Now, it's a matter of relationship. If AL-41F engine can appear here, there will certainly be many engine experts from bear country. Now, it's convenient to pack it and get it back. As for the paper technology of this engine, there are some in the cemetery.

In that parallel time and space, even if there is no xiongguo, Sukhoi design bureau still lives well by relying on the export of Su 27. Moreover, liulika design bureau is also very moist when Han countries continue to buy three aunt engines.

But now, the situation is completely different. The largest exporter of Su-27 is the Han country. Now, in the Han country, Su-27 is not needed at all. For the problem of engine, our side also has the turbofan 10 for mapping F110. At this time, the largest order of Sukhoi Design Bureau has disappeared.

Moreover, on the other hand, our J-11 fighters have begun to export, and will also compete with Su 27 in the international arms market. In contrast, our own side has the advantages of price and electronic technology, so the export prospect must be better than Su 27. If there is no competition, I'm afraid the whole aircraft industry in Xiong country will face great danger.

Don't say that later Da Mao and Han were good friends. When Han wanted to buy IL 76 and a big plane, Da Mao still tried his best to stop it. He was afraid that Han had obtained advanced technology. Therefore, Han unswervingly followed its own path and developed itself, which is the real benefit.

In this way, it is estimated that the life of liulika Design Bureau will be difficult, so we can get all their technicians. Come to Han and realize their life value!

What's this called? It should be the drunken man's intention, not in the bar.

Dr. Che Jin is an expert in this field and the chief designer of AL-41F engine. Such a person is needed by his own side. He must meet when he has a chance in the future.

Unfortunately, I can't go out now. To meet, I can only use each other. I don't know if the Jacques 141 fighter can succeed in asking for an engine?

It seems that you still need to fool yourself. Write another article to praise the Jacques 141 fighter! Qin Guan made up his mind.
