Chapter 194 The first sight of the J-10 (Part 2)
In the busy crowd, someone soon noticed the two people who had just walked in from outside.
"Old 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 the middle-aged men 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 himself clearly means that he will not be a casual character.
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 was 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. To deal with the problem, I 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, it was actually just the first time. Everyone who met quickly became familiar with each other.
"Lao Song happens to be on a business trip these two days, so we can only wait until the next time we meet 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 No. 10, Yang Wei, is capable. Very strong, I should be able to speak in common with you.”
“Hello, Comrade Chang Haonan.”
Yang Wei temporarily stopped what he was doing and shook hands with Chang Haonan:< br>
“I have 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 admired your name, Mr. Yang, for a long time."
Facing Yang Wei, who was only in his early thirties, at close range, Chang Haonan must be lying if he said he was not excited.
This is a real boss and a genius.
I graduated from junior high school at the age of 15 and took the college entrance examination without even attending high school for a day. I was admitted to Northwestern Polytechnical University. After graduation, I worked in the aviation system. It only took 7 years to become the director of the research office and the vice president of models. division.
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 as peers, so there is no need to be so polite. 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.
The main reason is that this efficiency is a bit exaggerated.
There are even gossips about whether this person is Du Yishan's illegitimate son or not. ...
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 He brought 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 think the calculations that Gong Yang is doing should have been studied in this area for a long time.”
The sharp-eyed Chang Haonan noticed that in this modeling, The six connections between the airway and the body have taken on 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 used for structural reinforcement, can actually play the role of rectifying and pulling vortices, further reducing the intake buffet and ensuring strict Air intake stability under conditions.
And we have already begun 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.
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).
“This is the future trend after all.”
Yang Wei nodded and admitted:
“But your paper did give me a lot of inspiration. Otherwise, the calculation results would not run so smoothly.”
“It’s just a pity that the No. 10 project was established relatively early, and most of the design materials are paper. We want to fully realize digital design and manufacturing. , we can only 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, which is the two-seater version, In the original timeline, Yang Wei was the first model to take the lead as the chief engineer.
“Actually, we are already trying to design the two-seater model at the same time, but due to the limited size of the design team, the progress is still slower.”
Yang Wei nodded:< br>
"But if you can join in later, the work in this area should be accelerated a lot."
Chang Haonan did not answer directly this time, but quietly looked at No. 01, which was about 70 to 80% completed. Prototype machine, he mentally summarized the changes he planned to make later.
In addition to replacing the DSI air inlet, 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 requires this capability. The needs are 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% new technology application, it is naturally impossible to start test flights immediately after final assembly. There is still a lot of ground testing to be carried out.
In addition to verifying relevant technologies in advance, all the plans mentioned above 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 all goes well, it will be between April and May this year."
Yang Wei gave the timetable almost without thinking.
