That means that based on the known take-off weight of his previous life, Chen Nian can roughly deduce the lift that the lift fan needs to provide.

With this point in mind, it is much simpler to calculate the total pressure ratio data required by the lift fan.

"I will try to give the overall verification data. This may take a while. You can try to solve the engineering problems first."

"Such as materials, mechanical structures, etc."

"If necessary, some private enterprises can be introduced to reduce project pressure."

In the previous life, the research and development of J-20 actually attracted a large number of private enterprises as support. 611 actually did a good job in balancing confidentiality and efficiency. Chen Nian did not need to worry about this.

"I understand, don't worry about this."

Yang Wei patted his chest and said.

The biggest problem has been solved for you. Do you still think it is difficult to solve these minor problems?

Although the mechanical structure is not simple, especially the manufacturing of the transmission system, it can almost be said to challenge the limit of China's processing capabilities at this stage, but as long as there is a way to go, it doesn't matter.

No big deal, just have to manually grind it bit by bit.

Once the verification machine comes out, subsequent standardization will be much easier.

The two discussed some details, and it wasn't until after twelve o'clock that Chen Nian finally followed Yang Wei to the restaurant with unfinished business.

The specifications of this reception really surprised Chen Nian.

It's not expensive, but in addition to classic Sichuan cuisine, there are also specialties from Chen Nian's hometown.

Although it is not authentic, it still gives him some comfort as a wanderer who has been in a foreign land for a long time.

After all, the last time he ate these dishes was when his parents were arranged to travel to NPU.

After the meal, the guests and hosts enjoyed themselves.

In the afternoon, Chen Nian immediately threw himself into work. In order to familiarize him with the environment and work system as soon as possible, Yang Wei personally took charge of him.

"We are now all using paperless design, which means that the design work has jumped from two-dimensional to three-dimensional."

"These softwares are all new and not everyone is very familiar with them yet."

"However, once you get used to it, both efficiency and confidentiality will be greatly improved, so I think it's worth it."

"Here, let me teach you how to use this."

"It's okay, I can use it."

Chen Nian smiled and replied.

Are you kidding me? As a person who traveled back in time from 2022, how can I still not know how to use CAD and CATIA?

Not only these, but also the later Nastran, FLUENT, and LS-DYNA, he can be said to be at his fingertips.

After all, this is the guy who eats.

Back then, he also spent a lot of time studying.

Seeing Chen Nian's skillful movements, Yang Wei couldn't help but be stunned.

He really didn't know how to explain what he saw.

You must know that paperless design is not yet popular in this era. The most typical one is that the original design of J-Shi did not completely get rid of paper.

Although there is learning about design software in university courses, they are all basic introductions. If you want to be proficient in it, you must go through a lot of practical operations.

Look at Chen Nian's attitude.

Fingers are flying, all kinds of shortcut keys are familiar, just from the aspect of using the software, it is much better than myself.

This thing cannot be explained by "genius".

If I had to describe my feelings at this moment, it was as if there was a soul that didn't belong to this era living in the other person's body.

He stared blankly for a few seconds, then finally came back to his senses and said:

"Very good, very good. If you know how to use it, then I won't bother you. I'll tell you how to access the database and how to call historical data."

Chen Nian really didn't know this. After all, each research institute's authority management system is different.

It took more than an hour for Chen Nian to finally understand all the 611 tools, and the speed amazed Yang Wei.

"Young people are young people. They learn so fast. It took me a month to figure out this system myself."

Chen Nian didn't speak, just smiled and said:

"The tools are easy to learn, but how to use them is hard to come by. By the way, Mr. Yang, I have a request, can you help me?"

"Say! If you have any requests, just ask, I will try my best to solve it for you!"

Chen Nian nodded and continued:

"I want to find someone."

"Looking for someone? Something to do with the lift fan?"

"Yes, I'm looking for Chen Yunyong from Yizha Laboratory - logically speaking, he is still your junior brother."

"Chen Yunyong?"

Yang Wei repeated it subconsciously, and after thinking for a moment, he answered:

"I know this person and have dealt with him before."

"However, when I left the Cascade Laboratory of NPU, he had just entered, so we can't say we have a deep friendship."

"But I remember, isn't he an engine developer? Can he be used for the lift fan?"

"It comes in handy."

Chen Nian said with certainty.

He clearly remembered that later, around 2015, it was Chen Yunyong who led Chengdu Aircraft's thrust fan project and achieved breakthrough progress in just two years.

There is absolutely no doubt about his ability.

You know, Shen Fei did not have a thrust fan project, but from the establishment of the project in 1995 until the year he traveled through time, it did not make any splash.

This is also the reason why neither Yang Wei nor Chen Nian chose to go to Shen Fei to ask for someone.

At least in this event, they paddled too hard.

"Okay, I'll help you find it."

"But, to be honest, this might be a bit difficult."

"Difficult? Why?"

"He is not in the country now, but in the United States."

"America?? Real or fake? Are you sure it's Chen Yunyong??"

Chen Nian was shocked.

In his memory, there was no period when Chen Yunyong went to the United States, so he always thought that the other party was just like Yang Wei, who had always been developing in China.

"This is very certain. He went to the United States after graduating from Western Polytechnic University. His original plan was to return to China within three years, but you also know the situation there."

"His procedures have never been completed. So far, he has been detained for five years."

"If we absolutely need him, we can try to contact him, but it's very difficult to do so."

"On the one hand, they won't release people there, and on the other hand, we also have confidentiality concerns."

"I understand. Let's try to contact him. In short, we have to bring him back no matter what - we can use Shen Fei's name."

"A paddling event is not so easy to attract attention."

"I see."

Yang Wei nodded, discussed with Chen Nian for a few more words, and then left the laboratory.

Chen Nian, who stayed where he was, felt a little emotional.

He didn't expect that such a master-level talent would experience such difficulties.

I don’t know how many scientists like him are forced to stay there.
Chapter completed!
