The military-industrial scientific research system of the academic master.

Among the busy crowd, someone soon noticed the two people who had just walked in from outside.

"Lao Lu?"

Lu Yuying is quite well-known in the 611 Institute, so even though she is wrapped in a cotton coat, she is still easily recognized.

One of them, a middle-aged man with a square face and half-white hair, took two steps forward.

Then he also noticed the young face following him, spent about half a second thinking about it, and finally determined that he had not seen him before.

Although the 611 family has a big business and it is impossible for everyone to know each other, being able to be taken into the 132 factory by Lu Yuying in person is obviously not a casual role.

Then the answer is obvious.

"This must be Comrade Chang Haonan."

"Hello, Mr. Xue, it's an honor to see you here!"

This time, Chang Haonan directly recognized the other party's identity.

The chief engineer of Project No. 10, Xue Chishou.

After the new management model was established in 1994, the chief engineer became the final decision-maker and person in charge of the entire project.

Equivalent to a big leader.

The chief designer is more concerned with specific technical issues.

"I have heard from Lao Lu and Lao Song before that there is a very capable rising star from Beijing Airlines, and he was invited to come to our 611 Institute, but he has been nailed to the 132 Factory for this period of time. I was dealing with the problem and didn’t have time to go back to the office to see you.”

Xue Chishou patted Chang Haonan on the shoulder, his tone full of kindness.

"That's why I asked Mr. Lu to bring me here to meet with your seniors in charge of Project No. 10."

Under the exchange of pleasantries, the people who were actually meeting for the first time quickly became familiar with each other.

"Old Song happens to be on a business trip these two days, so we can only wait until the next meeting to get to know each other."

Xue Chishou said with regret, and then pointed to a slightly younger engineer behind him who was checking data in front of a laptop:

"The deputy chief designer of Project 10, Yang Wei, is very capable and should be able to speak a common language with you."

"Hello, Comrade Chang Haonan."

Yang Wei temporarily stopped what he was doing and shook hands with Chang Haonan:

"I've heard about the situation in Haojing and Shengjing before, and solved many long-standing problems, but I still didn't expect you to be so young."

"I have also admired your name, Mr. Yang, for a long time."

Faced with Yang Wei who was only in his early thirties at close range, Chang Haonan would be lying if he said he wasn't excited.

This is a real boss and genius.

He graduated from junior high school at the age of 15 and took the college entrance examination without even attending high school for a day. He was admitted to Northwestern Polytechnical University. After graduation, he worked in the aviation system and became the director of the research office and deputy model chief engineer in only 7 years.

Chang Haonan once even doubted whether the other party was also cheating.

Otherwise it is really difficult to explain this career that is like the protagonist of a novel.

"Hey, we can be considered to be of the same generation, so there is no need to be so polite. Just call me Yang Gong, or just call me by my name."

Yang Wei waved his hand and replied.

From his point of view, he naturally felt that Chang Haonan was just a casual compliment.

After all, although he has been involved in several key models and has been promoted very quickly, his status as deputy model chief engineer should not be well-known within the aviation industry.

If you really want to talk about it, it is probably not as famous as Chang Haonan, who has been the first person to complete advanced technological achievements three times in half a year.

Mainly because this efficiency is a bit exaggerated.

There was even some gossip about whether this person could be Du Yishan's illegitimate son.

……

The routine polite process did not last long, and the topic of the group of people quickly returned to the fighter jet in front of them.

"Although we have never met before, your integrated internal and external flow design method, as well as some simulation and computer-aided design ideas, have actually helped us a lot."

Yang Wei took Chang Haonan to the computer next to the plane.

The above shows the CFD simulation results of the J-10 inlet entrance under certain working conditions.

"I see that the calculations Yang Gong is doing should have been studied in this area for a long time."

The sharp-eyed Chang Haonan noticed that in this model, the six connections between the air inlet and the body had shown different angles.

The prototype that is about to complete final assembly is still the original design.

In other words, Yang Wei has noticed that the six ribs, which were originally only used for structural reinforcement, can actually play a role in rectifying and pulling vortices, further reducing intake buffeting and ensuring stable air intake under harsh conditions. sex.

And we have already started to carry out corresponding optimization design.

It's just that he can't predict the future after all, so he obviously needs to be more conservative when it comes to changing the design of the prototype.

In particular, this is the icing on the cake, and its priority must be lower than ensuring the first flight node.

Together with the other improvements proposed during the test flight, they will be used together when the No. 03 prototype is manufactured (02 is a static verification machine and will not be used for test flight).

"After all, this is the trend of the future."

Yang Wei nodded and admitted:

"But your paper did give me a lot of inspiration, otherwise the calculation results would not go so smoothly."

"It's just a pity that the No. 10 project was established relatively early, and most of the design materials are on paper. If you want to fully realize digital design and manufacturing, you have to wait for the next model."

In fact, both the J-8C and J-7F, which Chang Haonan personally handled, can be regarded as computer-aided design done halfway. Although they have produced very significant results, they are not as transparent as projects started from scratch.

"It doesn't matter. Just think of it as accumulating experience first, and then consider digital design from scratch when designing the J-10S later."

The J-10S, also known as the two-seater version, was the first model in which Yang Wei took the lead as the chief engineer in the original timeline.

"In fact, we are already trying to start designing the two-seater model simultaneously, but due to the limited size of the design team, the progress is still slower."

Yang Wei nodded:

"But if you can join in later, the work in this area should be faster."

Chang Haonan did not answer directly this time, but quietly looked at the No. 01 prototype, which was about to % completed, and mentally summarized the changes he planned to make later.

In addition to replacing the DSI air intake, the most important thing is to replace the domestic turbofan power and realize full digital control on this basis.

The second step is to upgrade the surge monitoring and control module in the flight control——

As a single-engine fighter, the J-10 has higher requirements for engine stability, and the demand for this capability is also the most urgent.

Finally, there are some details. In the previous J-10, there were many things that were not fatal, but were still a pity. He planned to improve them all.

"When will the final assembly of this No. 01 prototype be completed?"

Chang Haonan asked Yang Wei next to him.

For a brand-new aircraft with more than 60% of new technologies applied, it is naturally impossible to start test flights immediately after final assembly. There is still a lot of ground testing to be carried out.

All the plans mentioned above, in addition to verifying relevant technologies in advance, must rely on these test results to be carried out.

It can be said that there is nothing more he can do before the prototype rolls off the assembly line.

"If everything goes well, it will be between April and May this year."

Yang Wei gave the timetable almost without thinking.
