"It seems that Mr. Tu, you are very optimistic about the export of J-7M, this document should cite many of our traditional military procurement customers, but it is not clear whether everyone is optimistic about the project, after all, the shortcomings of J-7M are still inevitable. ”

Since we talked about Jian-VII, Wang Zhengguo happened to say that in order to successfully realize the cooperation between Shudu and South Africa, according to Wang Zhengguo's plan, it is necessary to optimize the allocation of various resources, and an indispensable link is the Jian-7 series.

Those who don't understand may be surprised, how can the new Gemini Star Duck in cooperation with South Africa be involved in the J-7?

In fact, there is no way, this time it will not only involve the J-7, but the plan will even involve the J-8 project. The so-called optimization of resource allocation is not only related to a variety of technical problems, but also involves the rise and fall of the entire aviation industry.

In order to achieve the goal, Wang Zhengguo inevitably said a little harshly, it must be known that the current J-7M fighter is still in the time of popularity, the model has reached the final stage of finalization, and will soon start large-scale production, and the first batch of orders for Jordan.

Pakistan, Egypt, Bangladesh, these traditional users of the procurement is almost a nail in the coffin, suddenly heard Wang Zhengguo sing the opposite, how could he be easily let go by Chief Tu, a little unhappy asked.

This young idea is really naïve: "Not good? Compared with the J-7, the current J-7M has been greatly improved in combat capability, if it is not good enough, then what is excellent, J-73?"

These words came out of the mouth of Chief Tu, with a strong smell of gunpowder, and it suddenly made Wang Zhengguo feel a huge pressure, originally talking about Jianqi M, but suddenly what did Jianqisan mean, your resentment is so difficult to eliminate?

Quickly shake your head and deny, J-7M does still have various problems, but this model is also a distinctive personality, compared with the J-73 that is still in the research and development stage at this time, the two are not at the same level at all, at least J-7M is a successful model.

It is Jianqisan, which can actually be regarded as the flashpoint of the contradiction between Shudu Institute and 123 Factory, and between the two units before this, it has always been well water and river water.

Even the factory-affiliated design institute under the leadership of the 123 factory Tu has always been very ambitious, and it is all kinds of efforts to annex the Shudu Institute whose influence at that time was very average, and it can even be said that the influence is low, but due to various problems, the two sides are still harmonious on the surface.

The real problem occurred when Jianjiu dismounted, and the meaning of Shudu's existence was to develop Jianjiu, and Jianjiu's dismount meant that Shudu would have no projects to do, so this was the best time for Factory 123 to annex Shudu.

It must be clear that the improvement and research and development of the J-7 series has always been the responsibility of the design institute of the 123 factory, and the design institute at the peak had more than 200 designers, with a total of more than 1,000 personnel, complete configurations, complete departments, and rich engineering experience.

The most critical point is that due to the relationship between J-7 export orders, designers often go abroad, and can get in touch with foreign aviation technology, with broad horizons and advanced thinking, which is one of the best in China, which is by no means comparable to Shudu, which is built behind closed doors.

It just so happened that at this time, the Air Force was dissatisfied with the progress of the Jian-8 in Fengtian, and learned that the Egyptian MiG-21 could achieve all-weather operations, and at this time, the double-engine flat-headed Jian-8 could only fight during the day, so there was the idea of imitation, which was the beginning of the Jian-73.

When the project began to be studied, the military shouted the slogan of purchasing 1,000 J-73s, which made the 123 factory, which has been responsible for the development and production of the J-7 series, very interested.

However, the creation makes people, and the high-level seems to have some other considerations, and actually gave the Jian-73 project to Shudu, who has never been in contact with the Jian-7 fighter, to lead, as compensation for the Jian-9 dismount.

Just look at this result, if the 123 factory can be happy, it would be strange that the Shudu that was originally clear that it was going to be annexed by itself actually turned over, not only was it not annexed, but also snatched the largest piece of meat in his bowl, which is the root of Chief Tu's dissatisfaction with Shudu.

Looking back at the Jian-7 itself, based on the different positioning of the Jian-73 project by the 123 Factory and Shudu, it has become the reason why Mr. Tu ruthlessly damaged Wang Zhengguo just now.

In the positioning of the general Tu, the J-73 is directly simple to survey, mapping, production, and then will focus on the J-7 series of major changes, in his opinion, the J-73's nose air intake configuration is backward, there is not much potential to be tapped, unless a major change.

On the other hand, at this time, the Shudu did not have the Jianjiu project, and it was not easy to have a project to fight for, if it was just simple surveying and mapping, on the one hand, it was an insult to the design and research institute, on the other hand, it also took into account that it would not take long to complete the surveying and mapping, so what did the institute rely on after that?

In the end, it was proposed to reverse the fuselage structure and aerodynamics on the basis of the MiG-21MF obtained from Egypt, but redesign the internal equipment to improve the combat capability of the J-73.

Without changing the aerodynamic design, it can also greatly improve the combat capability of the MiG-21 series fighters, anyway, Wang Zhengguo is not sure how his father persuaded the top management to agree to this plan.

Maybe..... Or this is the talent of Shudu, the follow-up No. 10 project, isn't it also relying on the three-inch tongue to achieve the tiger's mouth, the difference is that the No. 10 finally succeeded, and the J-73 failed.

Even Wang Zhengguo didn't believe that the J-73 project at hand in Shudu could improve much performance, and he almost knew the J-7 series in his bones, and he could guess with his feet that in the face of Wang Zhengguo, a son from Shudu, and Wang Nanshou's son, he would not be normal.

"The J-73 project is indeed affected by factors other than various projects, so it has fallen to the current end, but we must also admit that the actual J-73 body is larger than the previous J-7 series, if the follow-up to improve the J-7 series, it is more appropriate to move the knife on the basis of the J-73. ”

J-7, or MiG-21 from the beginning of the model slowly developed to the end, the MiG design bureau has never changed the nose air intake plan, and the subsequent MiG-21 upgrades are to continue to expand the fuselage.

This line of thinking is like that of a Russian woman, who looks slim when she is young, and as she grows older, her figure grows sharply, and her body grows in circles and circles.

Look at the early MiG-21 fuselage, and then look at the final version of the MiG-21 Bis, the fuselage is really not a level, and it is definitely not just a lap if it is fat, and as a mid-term improvement model of the MiG-21, the MiG-21MF is also much fatter than the earlier model, and the natural J-73 fuselage is also fatter.

"Improvement? The improvement of the J-7 series is not to expand the fuselage, just the nose air intake design of the J-73, it will be difficult to improve it in the future, to be honest, you have taken a dead end in Shu. ”

In the end, Mr. Tu still said his evaluation of J 73 very pertinently: a dead end!

"Oh, then Chief Tu means to prepare for a major change in aerodynamics, like the Qiang Wu?

Wang Zhengguo knew that the Jian-7 CP project was also proposed during this time, and he thought that he had studied it when he came to Master Tu, and when he heard this, it seemed that he was not bad, so he pretended to be curious.

"That's right, if you want to redevelop the J-7 series and let him change the second spring, changing the aerodynamic design is the only way, and the rest is meaningless!"
