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 entered 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.

"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."

In the previous life, China's first aircraft carrier, the Liaoning, was renovated at the end of 2005 and was only launched and delivered in 2012. It is only the beginning of 2004. If it is started now, it will be two years ahead of schedule.

"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."

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

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

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

No wonder!

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

"Then this matter is settled?"

"...When you asked this, I thought it was you who asked for it in advance."

"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."

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

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

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?

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.

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

Chen Nian put down the phone dumbfounded and felt a little dazed for a moment.

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

Chen Nian smiled bitterly when he heard this. What do you mean it's not difficult?

"It's settled."

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.

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

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

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

"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!"

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

Chen Nian nodded subconsciously and replied:

"Mr. Yang, just say it!"

"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."

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

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

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

"Our aircraft carrier... won't be built in advance, right?"

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

Is it poaching?

After saying that, Yang Wei hung up the phone without giving Chen Nian time to regret it.

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

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

Thinking of this, he said:

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

Yang Wei asked.

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

"It's not too late or too early for us to build carrier-based aircraft now."

Chen Nian asked doubtfully.

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

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 its combat effectiveness, it had to either use new materials to reduce weight or use new ones.

engine.

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?"

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

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

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?"

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, and the body design needs to be modified.

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.

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.

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

"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."

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

"Varyag has entered the shipyard, and the transformation process should be accelerated. Anyway, Ma Weiming has passed, and he will be responsible for the ship's integrated power system."

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

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...

"It should be said that it was just the right time."

"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."

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

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

Thinking of this, Chen Nian replied:

"Why?"

Yang Wei said bluntly.

"Understood."

"Actually, I only need you to do three things."

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?"
To be continued...
