The research and development of the engine is definitely earlier than the whole machine, and only in the form of research and development such as Han Guo, there is an engine project with an aircraft project, which causes the engine to always be dragged down.

Xiong Guo’s Su-27 fighter jet has not yet flown for the first time. The prototype uses the Al21 turbojet engine. The AL31 turbofan engine has not yet come out. The Lulica Design Bureau has already begun the development of a new generation of engines. It was only in 1981. .

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

At that time, as an alternative to AL-41F, the R179-300 engine program was considered. This is a further development of the R-79V-300 engine. The thrust has reached the order of 20 tons, which is not small. However, after review by relevant departments, it is believed that the performance of the R179-300 engine is simply not comparable to the Al41F engine.

This engine started to be tested actually in 1988. The first batch of aircraft was installed on the aircraft for testing. However, for an engine, this test is destined to be long. of.

Just like our own turbofan six, it took a year to assemble it, and then it took more than ten years to test it. In the end, it failed to meet the requirements, and it had to stop research and development.

The same is true for this engine. When it steadily entered the sequence of research and development, the Xiong country was gone, and it lost a strong source of funding, and the engine did not continue to develop.

Later, the Rulika Design Bureau developed a new F117 engine using some of the results of this technology. In fact, it was based on the original Al31F and applied some AL41F technology. Even so, it was cherished by Xiong Guoren. I think how powerful it is, it is not exported to Han.

Now, when it comes to this kind of engine, Dongdukov certainly looks envious. Although the thrust of the engine is similar, the thrust-to-weight ratio of others is high. Under the same thrust, the weight of others is almost his own. In this way, at least one ton of structural weight can be saved, and these weights will become fuel or mounts, which will greatly improve the performance of the aircraft.

It's a pity that they can't get that kind of engine either.

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

"Yes, it is time to find the senior officials of Xiong Country to report, and find them to ask for the engine!" Even Mr. Gu was fooling around.

Twenty of these engines, the first prototypes, were built. Some of them were used for testing, and some were installed in Project 1.42 of the Mikoyan Design Bureau. They can all be used. Why Yakleev designed Can the bureau’s plane be used? Their airplanes are also trans-era!

As long as the Yakleev Design Bureau asks for it, then oneself will be able to obtain all the parameters. If this kind of engine is really so powerful, it is also good to be used on one's own stealth vertical take-off and landing fighter, at least in the design At that time, many technical indicators can be taken into consideration.

Of course Mr. Gu knew that this was beneficial.

In fact, Qin Guan is mainly preparing for the F-15. Of course, this is just a handy thing. After all, this engine has not been developed successfully. Even if it is obtained by himself, it is a prototype at most, and there are many more. The problem has not been solved. Although R79 has many problems, after all, it can already operate stably, otherwise Lu will not be in the same position.

Qin Guan’s biggest intention is that the drunkard’s intention is not to drink. What he values ​​is those designers. When he was researching the turbofan 15, he had his own system to help, and it took a lot of setbacks because of lack. Talent.

When the country of Xiong collapsed, Qin Guan wanted to dig out a large number of talents from the country of Xiong. Anyone who should come will have to come over, so that Han country will quickly become a powerful scientific research country. Said that Xiong Guo has no more nostalgia.

Now, it’s a relationship. If there is an AL-41F engine here, there will definitely be a lot of engine experts from Xiong Country. Now it’s convenient to pack and get it back later. As for the paper technology of this engine, There are in the cemetery.

In that parallel time and space, even if the country of Xiong is gone, relying on the export of Su-27, the Sukhoi Design Bureau is still alive and well. Moreover, with the country of Han who constantly buys the third uncle’s engine, the Design Bureau of Lulica is also very good. Moisturize.

But now, the situation is completely different. The largest exporter of the Su-27 is Han. Now in Han, there is no need for the Su-27. For the engine problem, we already have a turbofan 10 for surveying and mapping F110. At this time, the largest order of the Sukhoi Design Bureau has disappeared.

Moreover, on the other hand, one's own F-11 fighters have begun to be exported. In the international arms market, they will also compete with the Su-27. In contrast, one's own has the advantage of price and electronic technology, so it is exported The prospect is definitely better than that of the Su-27. If there is no competition, the entire aircraft industry in the country of Xiong will probably face great danger.

Don’t say that the later Da Mao and Han were good friends. When Han wanted to buy the Il-76 and bought a large aircraft, Da Mao still tried his best to stop it, because he was afraid that Han had acquired advanced technology. Therefore, Han was unswerving. Going on your own path and developing yourself are the real benefits.

As a result, the life of the Lika Design Bureau is estimated to be difficult, so we can get all their technical staff. Come to Han and realize their value in life!

What is this called? It should be that the drunkard is not in the bar.

Dr. Che Jin is an expert in this field and the chief designer of the Al-41F engine. Such a person is needed by himself. If he has the opportunity in the future, he must meet him.

It's a pity that I can't go out now. If you want to meet, you can only bring the other party over. I don't know if the Yak 141 fighter wants the engine, can it succeed?

It seems that you still need to fudge yourself, and write another article to praise the Yak-141 fighter! Qin Guan made up his mind.
