You come to fight J-20

"It's me. I thought Lao Chen never mentioned me to you."

Yang Wei's tone became more relaxed, while on this side, Chen Nian rubbed his face severely.

Who is Yang Wei?

There are two things everyone knows about him.

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

Second, he didn't finish high school.

In an interview at that time, his original words were:

"I didn't have much preparation. I just filled in the freshman class at Tsinghua University and Peking University. I got good grades and was only one or two points away from the junior class. I went to university not long after..."

When he went to college, he was only 15 years old.

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

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

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

——

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

Chen Nian thought in confusion that at this time, the J-20 project must have just entered a critical period. All designs were facing verification experiments, and a large number of plans were eliminated between 2004 and 2005.

Logically speaking, Yang Wei, who serves as the chief designer, should be so busy that he still has time to call himself?

I had never heard Chen Guo say that he was looking for me before.

Is it poaching?

It's possible, but calling at this time is really not an ordinary person's style...

Thinking of this, Chen Nian replied:

"Why don't you use Professor Chen to introduce you? Everyone who works on airplanes knows you. I just didn't realize it for the moment..."

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

"If someone else had said this, I would have smiled and admitted it, but in front of you, I really don't dare to be arrogant."

"The J-22's first flight was a full eight years ahead of our expected fourth-generation aircraft's first flight. When we heard the news, everyone in our department was dumbfounded."

"I know you are also working on fourth-generation machines, but I didn't know you were so fast..."

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

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

Chen Nian nodded subconsciously and replied:

"Mr. Yang, just say it!"

"I want you to be the 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 other party's intention, Chen Nian still couldn't help but feel a little confused when Yang Wei sent out the invitation.

You must know that the reason why he can lead the design and R&D work of the J-22 is because he directly used the system to analyze the F22. He knows all the details of the aircraft. He also knows its design advantages and disadvantages and can propose optimizations.

suggestion.

But if it is placed on the J-20...

The design concept of the J-20 is very different from that of the F22. 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.

As for analyzing the future J-20...

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

Therefore, Chen Nian never thought about getting involved in the J-20 project. He knew that he could not help much.

After hearing Chen Nian's answer, Yang Wei on the opposite side did not show any disappointment at all, but continued to ask:

"Don't you ask me first what I want you to do?"

"Um...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 cannot apply the experience of the J-22 to the J-20."

"As for some general technologies and theories, you can actually just go to 601 to get them."

"Now that technology is shared and interoperable, there is no need to add a role like mine."

Chen Nian's tone was very sincere, but Yang Wei seemed not to be convinced at all.

"You are wrong, we need your role now."

"Why?"

Chen Nian asked doubtfully.

"Because we know what you are doing and what you want, and we are willing to do it according to your ideas."

"Let me ask you a question: What do you think of the J-20 being launched on the ship?"

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

"You want to change the J-20 into a carrier-based aircraft? You want to go on the flat deck? Varyag... no more?"

Yang Wei seemed to be very satisfied with Chen Nian's reaction. He chuckled and replied:

"Of course Varyag is still needed, but its status is more like a 'technology verification aircraft carrier'. In the above plan, flat deck, electromagnetic catapult, 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-20 still has a chance."

"As you probably know, the J-20 adopts a canard layout, which has advantages at low speeds and high angles of attack. If corresponding optimization can be carried out, 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 for the domestic aircraft carrier project, right? Don't you want to get it right in one step so that our first aircraft carrier will have the best carrier-based aircraft?"

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

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

But the problem is, it’s not easy!

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

The main wing must be lengthened and the canards must be reduced. At the same time, the changes in airfoil vortices caused by such changes must also be considered.

On the other hand, the original maximum take-off weight of the J-20 was 39 tons, which was a bit too heavy for a carrier-based aircraft. Without reducing combat effectiveness, either new materials were used to reduce weight, or new materials were needed.

engine.

In addition, 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 same ones that I have solved one by one in Project No. 22?

No wonder!

Chen Nian secretly sighed in his heart. He was worthy of being a person who went to college at the age of 15. Not only did he have outstanding personal abilities, but he also had a unique method of poaching people...

Thinking of this, he said:

"Mr. Yang, I understand what you mean."

"So what do you want me to be responsible for? Engines, materials and airframe design?"

"Smart! I know you are definitely not a nerd!"

"Actually, I only 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 maritime take-off and landing environment. Of course, it would be best if the thrust could be larger."

"Second, make suggestions on the J-20's aerodynamic layout and participate in discussions to come up with the best plan."

"Third, on the basis of the original new materials, let's see if we can make some optimizations to increase strength and reduce weight."

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