Spark

It's me. I thought Lao Chen hadn't mentioned me to you.

Yang Wei's tone relaxed a bit, but on the other side, Chen Nian rubbed his face hard.

Who is Yang Wei?

There are two things that are well known about him.

First, he is the chief designer of the J-20.

Second, he didn't finish high school.

When interviewed at the time, his original words were:

I don't have any preparations. I just filled out Tsinghua University and Peking University. I passed the test well, and I was only one or two points away from the junior class. I will go to university soon...

When he was in college, he was only 15 years old.

And just 10 years later, he achieved the most important technological breakthrough of the third-generation domestic aircraft, that is, a breakthrough in the fly-by-wire flight control system, making the third-generation domestic aircraft possible.

Later, he participated in the design optimization of the J-10 and Xiaolong, and after the establishment of the J-20 project, he served as the chief designer of the J-20 project.

The brilliance of this resume is probably unmatched in the history of domestic military industry development.

——

But here comes the question, why is he looking for me?

Chen Nian wondered, at this time, the J-20 project should have just entered a critical period, and all designs were facing verification experiments, and a large number of plans were eliminated in 2004-2005.

Logically speaking, Yang Wei, who is the chief designer, should be so busy that the soles of his feet are smoking, but he still has time to call himself?

I hadn't heard Chen Guo say that he was looking for her before.

Could it be poaching?

It's possible, but it's really not the style of ordinary people to make a phone call at this time...

Thinking of this, Chen Nian replied:

Why should I use Professor Chen to introduce you? Everyone who builds airplanes knows you, but I just didn't realize it for a while...

Hearing his words, Yang Wei on the opposite side smiled and said:

If someone else said this, I would admit it with a smile, but in front of you, I really don't dare to be arrogant.

The first flight of the J-22 was 8 years ahead of our expected first flight of the fourth-generation aircraft. When we heard the news, everyone in our institute was dumbfounded.

I know that you are also working on the fourth-generation machine, but I really didn't know that you are so fast...

Having said that, Yang Wei paused for a moment, then continued:

I won't say much about congratulations, Chen Nian, I have something to discuss with you today, so let's get straight to the point?

Chen Nian nodded subconsciously, and replied:

Mr. Yang, just say it straight!

I want you to be a consultant for the J-20 project!

Yang Wei said bluntly.

Being a consultant...I'm afraid I can't do it.

Although he had already guessed the intention of the other party, when Yang Wei sent out the invitation, Chen Nian still couldn't help feeling a little embarrassed.

You know, the reason why he was able to lead the design and development of the J-22 was because he directly analyzed the F22 with the system, knew all the details of this aircraft, knew its design advantages and disadvantages, and was able to propose optimizations. suggestion.

But if you put it on the J-20...

The design concept of the J-20 is very different from that of the F22, and the experience accumulated in the No. 22 project cannot be directly used on the J-20.

And if you rely purely on your own professional knowledge, it is not enough to support the entire project for the time being.

As for analyzing the future J-20...

Don't be kidding, Chen Nian will never do such a pure waste of resources.

Therefore, Chen Nian never thought of getting involved in the J-20 project, he knew he couldn't be of much help.

Hearing Chen Nian's answer, Yang Wei on the opposite side showed no disappointment, but continued to ask:

Aren't you going to ask me what I want you to do first?

Uh...Mr. Yang, to be honest, no matter what I do, the role I can play is very limited.

The overall design logic of the J-22 is almost completely different from that of the J-20. I can't apply the experience of the J-22 to the J-20.

And if it's some common techniques and theories, in fact, you can just ask 601 to get them.

It's all technology sharing and interoperability now, so there's no need to add a role like me.

Chen Nian's tone was very sincere, but Yang Wei didn't seem to be convinced at all.

You are wrong, we need your role now.

Why?

Chen Nian asked suspiciously.

Because we know what you're doing, we know what you want, and we'd love to do what you want.

I'll just ask you a question: what do you think of the J-20 being on board?

Chen Nian suddenly stood up, his eyes widened, and he asked in disbelief:

You want to change the J-20 into a carrier-based aircraft?? You want to go to the flat deck? Varyag... don't want it anymore?

Yang Wei seemed satisfied with Chen Nian's reaction, he chuckled lightly, and answered:

Of course Varyag is still needed, but its status is more like a 'technical verification aircraft carrier'. In the above plan, flat deck, electromagnetic ejection, and large tonnage are the real direction.

So, under the premise that flat decks are the mainstream, we must prepare for this in advance.

The design of the J-22 has been finalized. It is destined to be impossible to be used as a carrier-based aircraft, but the J-22 still has a chance.

As you probably know, the J-20 adopts a canard layout, which has an advantage at low speed and high angle of attack. If it can be optimized accordingly, it may become the most threatening carrier-based aircraft in the world!

Chen Nian, although I have not been included in the Spark working group, my confidentiality authority is very high, and I know most of the information.

You are pushing the domestic aircraft carrier project, right? Don't you want to do it in one step and let our first aircraft carrier have the best carrier-based aircraft?

After listening to Yang Wei's words, Chen Nian fell into deep thought.

The J-20 boarded the ship... The temptation of this thing was too great for him.

But the problem is, the difficulty is not small!

The aspect ratio of the J-20 is only 2.3, which is pitifully small compared to the 2.76 aspect ratio of the F-35, and the airframe design needs to be modified.

It is necessary to lengthen the main wing and shrink the canard, and at the same time, the change of the wing surface vortex caused by such changes must also be considered.

On the other hand, the original J-20 has a maximum take-off weight of 39 tons, which is a bit too heavy for a carrier-based aircraft. Under the premise of not reducing combat effectiveness, it is necessary to use new materials to reduce weight, or to install new ones. engine.

In addition, the structural strength is also a big problem. It is estimated that even the materials of the body will have to be replaced...

——

Why? ? ?

Chen Nian suddenly reacted.

Aren't these problems the ones I have solved one by one in Project No. 22?

No wonder!

Chen Nian secretly sighed in his heart, he deserves to be a person who went to college at the age of 15, not only has outstanding personal ability, but also has excellent methods of poaching people...

Thinking of this, he said:

Mr. Yang, I understand what you mean.

So what do you want me to do? Engines, materials and airframe design?

Smart! I know you're definitely not a nerd!

Actually, I just need you to do three things.

First, come up with a modification plan for the current F119 engine so that it can adapt to the sea take-off and landing environment. Of course, it would be best if the thrust could be a little bigger.

Second, make suggestions on the aerodynamic layout of the J-20 and participate in the discussion. It is best to be able to come up with a plan.

Third, on the basis of the original new material, see if it can be optimized to improve strength and reduce weight.

There are no hard requirements for these three things. You can help if you can, and it doesn't matter if you can't—but I believe you will give us a surprise, because this is not difficult for you.

Chen Nian smiled wryly when he heard that, what do you mean it's not difficult?

Even with the help of system analysis, it is still difficult, okay?

——

However, it's not impossible.

Okay, you convinced me... But Mr. Yang, I want to ask, is it too early to consider the issue of carrier-based aircraft?

Our aircraft carrier... won't be done in advance, will it?

In the last life, China’s first aircraft carrier, namely the Liaoning ship, began to be remodeled at the end of 2005, and was launched and delivered in 2012. It is only at the beginning of 2004. If it is launched now, it is equivalent to two years in advance.

...You asked this question, I thought you asked for it in advance.

Varyag has already entered the dock, and the transformation process should also be accelerated. Anyway, Ma Weiming has passed away, and he will be in charge of the ship's comprehensive electrical system.

It's not too late or too early for us to engage in carrier-based aircraft.

It should be said that it is just in time.

Understood.

Chen Nian scratched his head, he really hadn't heard the news - but the report seemed to be thrown on his desk, but he was too busy these two days to read it...

Then this matter is settled?

Yang Wei asked.

That's a deal.

Okay, then I'll go say hello to Lin Yongming, and I'll solve the permission issue!

After finishing speaking, Yang Wei hung up the phone neatly, without giving Chen Nian time to regret it.

Chen Nian put down the phone dumbfounded, feeling a little dazed for a moment.

Varyag has entered the dock, and the ship-borne version of the J-20 has been launched.

That shows that because of his appearance, the progress of some major projects is speeding up.

This is exactly the result I wanted.

ten thousand years is too long, fight for now.

Within 20 years, he will reverse the pattern of this world!
