History still has its inertia. Pen "Fun" Pavilion www.biquge.info

After getting the Su-27, the Air Force immediately had a green eye for the AL-31F engine as a spare part. Looking at the vortex 15 that has been developed for ten years, but still only hears the sound of the stairs and no one comes down, it is impossible to have no resentment.

Pinning hopes on the Dawn plant to complete the imitation of the turbojet 15 on time is obviously not very reliable. The Taihang turbofan engine, which was originally planned to be used for the No. 10 project, may only be "not very good" for a considerable period of time.

According to the historical progress, Taihang is not to mention the nineties, and the installation rate of Taihang B thirty years later is still very touching. Otherwise, during the test flight of the J-20A, it will not be necessary to continue to use the third aunt.

The third aunt is actually loved and hated in China, and he loves it because there is such a channel to get excellent aviation development when the country is in a state of flux. Hate is the same, whoever makes the domestic aviation development really unlucky, can only hang himself on the tree of Maozi.

It is conceivable that because the third aunt will suffer a lot of splint gas in Maozi.

It seems unlikely that a matching domestic engine will be available under the schedule of Project 10.

In this case, there is an opportunity to get the AL-31F from the Soviet Union, so why not use this engine on the 10th? The Air Force does not know who it is, and suddenly opened such a brain hole.

Obviously, no matter how good an airplane or car is, an F1 driver cannot be an expert in car design, and an Air Force pilot is not an expert in aircraft design.

The Air Force does not know what a big project it is to change the issue of a fighter that is close to being finalized.

Moreover, the AL-31F was originally only used as a supporting match for the Su-27, a twin-engine heavy fighter, and the technical requirements are very different from the single-engine medium fighter of the 10th.

To put it simply, twin-engine fighters do not attach so much importance to the reliability of their engines. The Su-27 has two chrysanthemums, and if there is a problem with one engine, it can also fly back with the power of the other.

However, if there is a problem with the engine of the 10th in the air, the only result is that the plane crashes, and if you are unlucky, the pilot's life may be in danger.

In fact, the reliability of the AL-31F has indeed become a problem for No. 10. Due to a congenital defect in the design of the lubricating oil supply system, the bearing system of the third aunt could become very unreliable during the period of intense operation.

As a fighter jet, the 10 will obviously face harsh and drastic engine conditions many times during the flight.

The No. 10 flight accident caused by the third aunt is best known for a crash in Taizhou during training for the East China Sea Fleet in 2015. In order to avoid the densely populated area, the pilot insisted on holding on until the altitude was reduced to more than 200 meters before finally parachuting.

At this altitude, there is almost no difference between a fighter parachuting and being close to the ground.

Of course, the engine problem is also very prominent on the original F-14A. The poor reliability of the TF-30 has made the average failure rate of the F-14 reach 6 times per 100,000 hours, which is 20% higher than the average accident rate of US Navy fighters!! (MISSING)! (MISSING)! (MISSING)! (MISSING)! (MISSING)! (MISSING)! (MISSING)! (MISSING)! (MISSING)。 (MISSING)

When filming Top Gun, the U.S. Navy even sacrificed a general because of engine problems.

At the strong request of the Navy pilots, Grumman finally replaced the F-14 with F110-GE-400 engines, which solved the heart attack that the F-14 brought from the mother's womb.

It can be seen that all countries in the world have very high requirements for the reliability of fighter engines. Although the design flaws of the AL-31F did not affect the performance of the J-10, the "contribution" to the flight failure rate was not small.

Of course, Hu Wenhai knows this history well, and if Project No. 10 can solve the problem of the engine, it is of course best not to use a third uncle.

But the problem is that looking at the country, it seems that there is no chance of solving the No. 10 engineering engine.

Wait a minute.

I'm afraid that's not the case.

Song Wencong glanced at Tu Jida, hesitated for a moment, and then continued: "I heard that Mr. Hu has a complete set of technical data for the Soviet R-35 turbojet engine? As a successor to the R-29 engine, its performance should be better than that of the turbojet 15. ”

Hu Wenhai slapped his forehead when he heard this, and suddenly realized.

The imitation object of the turbojet 15 is the design parameters obtained by reverse mapping of the R-29 turbojet engine on the MiG-23 obtained by China from Egypt.

The MiG-23 was once equipped with four engines, corresponding to different models. The MiG-23S is equipped with R-27, the MiG-23M is equipped with R-29, the MiG-23ML is equipped with R-35, and the MiG-23B is equipped with AL-21F.

Since the turbojet 15 engine that imitates the R-29 is difficult to produce, it is necessary to copy the R-35 with a full set of technical data, which can also replace the turbojet 15 to provide supporting facilities for the No. 10 project.

The R-35 not only has more thrust than the R-29, but also has a thrust-to-weight ratio of 7.2, while the turbojet 15 has a thrust-to-weight ratio of only 6.5. Whether it's performance, reliability or maintainability, this engine can be satisfied. In fact, since the R-35, the Soviet Union's engine research and development has shifted to turbofan technology, which means that the R-35 can actually be regarded as the last generation of turbojet.

And most importantly, the MiG-23 has a little in common with the Ten, they are both single-engine fighters!

That is, the reliability of the R-35 is high and is able to fit the needs of a single-engine fighter.

Song Wencong learned the news of the R-35 from Wu Daguan during the information exchange between Project 10 and the Panda project team, and he couldn't wait to find the imperial capital during the Asian Games.

The most important thing is that the technical information of the R-35 in Hu Wenhai's hands is not only the design and process data of the engine.

At that time, the KGB used Hu Wenhai's policy of calculating prices by weight, but they wasted their brains digging up all the information related to the R-35. As long as it has something to do with the R-35, I will collect everything regardless of it.

This document can be said to cover almost everything related to R-35, from the most basic materials to tooling and fixtures, from design ideas to parameter calculations, from final assembly processes to software integration.

Although the R-35 was already developed and produced in the seventies, it was equipped with the MiG-23 fighter, which now seems to be slightly outdated in combat effectiveness. However, China's aero engine industry has never had such a complete understanding of the entire development process of a turbojet engine.

For China, which fell out with the Soviet Union early, the road to self-development of aero engines is too tortuous. Imitation and sporadic information obtained from some channels are obviously not enough for China's aviation engine industry to fully understand the research and development ideas of turbojet engines.

From this point of view, the batch of information obtained by Hu Wenhai is really too valuable.

Thinking of this, Hu Wenhai suddenly burst out laughing.

He really didn't expect that the information he had just gotten for the two Wu elders for reference on a whim turned out to be so useful!

"Since Mr. Song thinks this batch of materials is useful, then use it and use it well!" Hu Wenhai touched his head and said hesitantly: "This batch of materials was originally used to help the development of domestic aviation development, if Mr. Song can use it, it means that my money is not in vain." I'm a private company, and turbojet engines are useless. Since Project 10 is in need, I will have a copy of the materials for you to take. ”

As Hu Wenhai spoke, he raised his hand and blocked back what Song Wencong was about to say: "Mr. Song, don't mention the matter of money, what about me?"

Hearing Hu Wenhai's words, Song Wencong, Liu Daxiang, and Jiang Hefu glanced at each other and couldn't help but breathe a sigh of relief.

It was not surprising that Hu Wenhai was able to agree to this request so happily. This batch of materials was originally kept in the hands of the Power Research Institute presided over by Wu Daguan, and it was actually a set of teams and two brands with the engine laboratory of the Panda project.

The Power Research Institute is responsible for a wide range of projects, such as micro turbojets, gas and steam turbines, as well as many power technologies. Technologies such as fuel cells, high-voltage power transmission, frequency converters, power switches, and electric motor traction drives are all within its scope of research.

The aero-engine is just a research institute under the Power Research Institute, and it is difficult for the outside world to know what kind of information it holds internally when the technology circulation was not smooth in the 80s.

Fortunately, it was with the background of cooperation between the two projects that the information about the R-35 surfaced.

And as Hu Wenhai said, the information on the new R-35 is not of much use, and opening it to Song Wencong and the No. 10 project can be regarded as making the best use of it, so why not do it.

However, even if they were mentally prepared, Song Wencong and others still felt overjoyed with Hu Wenhai's generous decision. According to their original plan, they were ready to buy it with real money, after all, this batch of materials did not fall from the sky.

Hu Wenhai's generous and free opening was indeed a bit unexpected for them.

Tu Jida stood up at the right time, shook his head and said to Song Wencong and the others: "Old Song, you see I have said a long time ago that Mr. Hu is very supportive of our military work." ”

"My fault, it's indeed my fault!" Song Wencong couldn't help but laugh, nodded and said: "I heard about Mr. Hu before I came, but I haven't seen it in person, so I can't help but have some doubts......

"How do you feel about meeting now?"

Song Wencong couldn't help but give a thumbs up, and sighed: "It's better to be famous than to meet, take it!"

Hu Wenhai's reputation as "Sai Mengwei" is also well-known in the domestic military industry. However, in this era, domestic thinking is still slightly conservative, and it is the normal line to find the country when there is a problem. When it comes to the individual, it is inevitable that there will be some concerns about the military industrial system.

Most people, even if they heard about Hu Wenhai, regarded it as an urban legend. Even in Song Wencong's heart, he actually didn't believe that a private business owner would be so generous.

But facts speak louder than words, who would have thought that as the richest man in the world, making money is only a secondary job, and the main job of returning from rebirth is actually "aiding the Communist Party"?

Mr. Hu's main business is really a bit hard, not only can not be hyped up, but also to make people understand, it is really "I am also desperate"!
