The AL-31FN introduction project was officially terminated, and its influence spread rapidly to various fields.

The J-10, which has been basically finalized, was returned to the airframe design link in order to adapt to the domestic WS-10A engine.

The work intensity of Beihang Materials Institute has almost doubled, the purpose is to explore the standard industrial preparation process of new nickel-iron alloys and titanium-aluminum alloys.

The 601st, 606th, Chengfei, and Shenfei have all entered the state of full-load operation. They must either rely on new projects to develop new fighter jets, or try their best to install the only 26 AL-31FNs on the J-10 , Let these J-10s display their combat effectiveness in the shortest possible time.

In the minds of everyone, even the most optimistic researcher, they feel that perhaps for a long time in the future, the sky of the Republic will have to be guarded by these 26 third-generation aircraft.

However, while everyone is worried about this decision, only one person is completely optimistic, even cheering.

That is Chen Nian.

The AL-31FN matter has finally come to an end!

Although the matter promoted by himself seems a bit radical, it only appears radical when the future cannot be predicted.

In another year at most, even without any "technical assistance" from itself, WS-10A can successfully pass the assessment and go offline. At that time, this engine with transonic design, hollow blade design, and three-dimensional aerodynamic design will Enough to make up for the vacancy of AL-31FN.

Can't we even make it through a year?

That is absolutely impossible!

The pain of this year can magnify the expected benefits several times and directly strengthen our air force in one step.

So in comparison, what are the short-term difficulties?

What's more, now there is its own plug-in

The F-22 airframe design drawings have all been exported, experts from the 601 Institute have already started to act, the wind tunnel data was released two days ago, and various departments have also been mobilized. , It only takes three months at most, and the first "aircraft shell" can be manufactured.

Moreover, in this process, a large number of technologies will be fed back to other projects, thereby promoting the progress of other projects.

Overall, this choice is definitely a sure bet.

The only thing to worry about is whether the progress of the engine can catch up with the progress of the structure of the airframe.

He had completed the analysis of the F119 engine before, and he had already thought of a relatively convincing "hand-in method".

That is, throw out the technology bit by bit, get stuck on the progress of the project, and after the project team has overcome a difficulty, then throw out the next idea.

Since I am a "creative consultant", I must play the role of a creative consultant!

Isn't the advantage of this position that you can put forward your own ideas unscrupulously!

Thinking of this, Chen Nian picked up the phone.

He didn't call Chen Guo, but directly found Lei Gang.

The reason is very simple. What he is going to say next has nothing to do with the design of the body.

That's information about the F119 engine.

The phone rang twice before it was picked up immediately, and Lei Gang's voice on the other end seemed a little excited.

"Xiao Chen, I just wanted to call you!"

"Have you seen the news? The introduction plan of AL-31FN has been stopped!"

"The higher-ups allocated a large budget to Institute 606 for the optimization and improvement of domestically produced engines. I guess this time, we really have to do it ourselves!"

"By the way, we have already started analyzing the body structure diagram you gave."

"In general, there are many problems and great achievements!"

"We found a few things that didn't make sense, but the fundamentals and usability are all right!"

"I've already reported to the above, and you are a big contributor to this project!"

Hearing Lei Gang's words, Chen Nian here smiled slightly.

Some mistakes and omissions in the structural diagram are inevitable, part of which is the "foreshadowing" that I deliberately put down, so as to avoid troubles caused by too perfect drawings.

On the other hand, it may indeed be that I made a mistake or missed a drawing.

After all, the difficulty and workload of producing such a blueprint is huge, and occasional minor problems are unavoidable.

He has checked it several times before handing it in, and there will be absolutely no fatal problems.

"It's good to be able to use it. I'm still worried that this thing is just my own fantasy."

Chen Nian replied modestly.

"Why can't it be used! It's so useful!"

"I didn't expect that, the surprises you gave me are really one after another!"

"I also chatted with Chen Guo that day, and he said that your theoretical knowledge is very solid, probably close to his level when he was a PhD student."

"With such a strong theory, coupled with your own ideas, it's no wonder you can come up with such a thing!"

"By the way, how was your latest class?"

Lei Gang seemed to feel that it was inappropriate for him to just talk about work, so he abruptly changed the subject and began to care about Chen Nian's study.

However, Chen Nian didn't intend to talk to him about these useless things.

He replied:

"It's not a big problem in learning, but I have a new idea, and I want to tell you about it and see what you think."

"you say!"

Chen Nian organized his language a little bit, and said:

"Aren't we going to make an engine? I also read some related books and documents when I was free recently."

"I noticed some new concepts of the engine, such as the integral blisk structure, adjustable guide vanes, double-layer floating wall flame tube, and single-stage high-low pressure turbine. These technologies are all used on the F119 engine."

"I want to ask, is it difficult to apply these technologies?"

Hearing Chen Nian's words, Lei Gang pondered for a moment, then replied:

"Generally speaking, there are some difficulties—I'm not kidding with you. These technologies are familiar to us. There are only two biggest problems."

"The first one is how to use the appropriate size to combine these technologies into a real engine."

"Second, when we know how to use it, what method should we use to achieve it."

"The former is a problem of data, and the latter is a problem of tools."

"The former can still be solved through trial and error, but I guess the latter can only be downgraded."

"For example, we can't do linear friction welding technology, but if we want to make a whole blisk, we can basically make do with diffusion welding"

"What if both problems could be solved?"

Chen Nian interrupted Lei Gang.

"What? What are you talking about? Solve it? How to solve it?"

Lei Gang was shocked. At this moment, a thought suddenly appeared in his heart:

That kid's question just now, can't it be a set question?

You know, every time he said "the problem can be solved" before, the problem was really solved.

And it was solved by him!

Chen Nian also realized that what he said was too hasty, so he quickly made amends:

"What I mean is, the first question is trial and error anyway, I can also try to get some data, what if it's suitable?"

"As for the second question, I really don't understand the linear friction welding technology, but I found the information. We already have axial linear friction equipment, and maybe there will be a breakthrough soon."

Hearing this, Lei Gang breathed a sigh of relief.

Good thing he didn't say "I know how to build linear friction welding equipment".

Otherwise, I really don't know how to explain it to my superiors.

However, he seems to say that the data will come out

The accuracy of the data that this kid produces every time is frighteningly high, if you let him try again.

Lei Gang was shocked and said:

"Forget about linear friction welding, let me figure out a solution!"

"But the data, you can try to get it out, you are lucky now, maybe it can save us a lot of things!"

A smile appeared on Chen Nian's face on the other end of the phone.

Still such a friendly team.

Before he even said anything, he had already taken the initiative to arrange the steps for himself
