215: The change is obvious

Despite this, he still smiled and stepped forward to shake Xu Ning's hand: "It seems you are already our little Junior Brother."

Xu Ning responded: "Once the exam week is over, I will officially join the team. Professor Du should introduce me to everyone then."

After checking the experimental equipment, Xu Ning turned on the power, "A few days ago, I saw you and Yao Meiling at the entrance of the cafeteria. I wanted to say hello, but unfortunately, I didn't catch you."

"Oh? You know Yao Meiling?" Fang Zheng asked in surprise.

"Yes, we discussed some academic matters." Xu Ning nodded.

"Yao Meiling is a very outstanding person. She went straight from undergraduate to doctoral studies. Learning more from her will definitely help you." Fang Zheng said sincerely.

In fact, ever since adopting the simulation algorithm proposed by Yao Meiling, although progress was slow at first, he gradually realized that it was indeed the correct method.

Fang Zheng admitted that perhaps his passion for scientific research was not as strong as Yao Meiling's.

And Xu Ning recalled his brief contact with Yao Meiling and felt that she seemed a little muddled.

However, he did not intend to argue too much on this topic.

"Well, her learning speed is indeed quite fast."

Afterwards, they turned to talking about the work at hand.

"Are you testing turbine blades?" Fang Zheng asked curiously, looking at the busy Xu Ning.

"No, this is just a regular fan blade project. But I'm trying to incorporate some R&D concepts from aero-engines as part of my self-improvement." Xu Ning explained.

Initially, this work was just to earn some extra income, but during the in-depth research process, he developed new insights into blade R&D.

Just as Xu Ning was adjusting the experimental setup, Fang Zheng explained his purpose for coming: "I just came back to get a book that I accidentally left here before."

Saying that, he held up a professional book about the DAMP programming language.

Xu Ning immediately became interested after seeing the title: "Wow, are you already doing secondary development of the MSC.Nastran software?"

Fang Zheng frowned, feeling that he had used the word "Huh?" more recently than in the previous month combined: "How did you know we were researching this?"

Xu Ning scratched his head, looking a bit embarrassed.

"Oh, when I saw Yao Meiling last time, she mentioned that you were trying to use the CFD/CSD coupling method for flutter analysis of straight wings, but the effect was not good.

I suggested to her at the time that she could try the dipole lattice method, and mentioned that it would require using the DAMP language to modify the software.

I really didn't expect you had already started."

Fang Zheng held a book in his hand and looked at Xu Ning in surprise: "You mean, this method was suggested by you to Yao Meiling?"

"Yes." Xu Ning nodded, and then recounted to Fang Zheng the content of the discussion with Yao Meiling that day.

The laboratory was quiet for a moment, with only the slight sound of airflow coming from the wind tunnel.

Fang Zheng hesitated several times before finally managing to squeeze out a sentence: "So, you are the senior she mentioned?"

"What do you mean?" This time it was Xu Ning who was confused.

"It's nothing." Fang Zheng said, suppressing a smile, "How about this, you join our team first to get familiar, and I'll arrange a good window seat for you."

"Okay." Xu Ning had planned to relax for a few days after the exams, but since there was an invitation, integrating in advance was also a good option, "Then I'll say hello to Professor Du first and officially join after the exams."

"Absolutely no problem, Professor Du will welcome you very much." Fang Zheng's smile was almost impossible to hide.

To prevent Xu Ning from noticing his excitement, Fang Zheng quickly turned aside and just happened to catch sight of the inconspicuous small fans on the table.

At this point, the test of the first prototype fan had just been completed.

Xu Ning carefully replaced it with the second fan, which was their first attempt at the optimized version.

When the power was turned on again, although it was not in a professional soundproof environment, the change in sound was obvious, and the noise was reduced.

"This fan you developed is really something." Fang Zheng leaned closer to carefully observe these fans that used curved R&D blades, "Can I take a closer look?"

As a researcher with six years of experience, he knew that experimental items should never be touched without permission.

"Be careful, don't drop it." Xu Ning said without hesitation, knowing that if Fang Zheng could unlock his R&D secrets just by observation, he would have been treated as a national treasure long ago.

"This looks like forward bend and forward sweep R&D?" Fang Zheng asked with a hint of doubt.

In engineering, "bend" and "sweep" represent two completely different ways of handling blade shapes.

The concept of adjusting blades to optimize airflow control already appeared in the 1960s and 1970s.

However, at that time, it relied more on the experience and intuition of Engineers rather than rigorous scientific theory.

So for Fang Zheng, having some knowledge of this was not surprising.

What Xu Ning was planning to do was to further explore the combined effect of "bend" and "sweep" based on this, hoping to provide a clearer direction for future blade R&D.

Of course, all of this was still in the initial stage.

"That's right, I want to test the working efficiency of blades under several different bend and sweep combinations.

But this is just a model fan, the airflow speed won't be too high."

As he spoke, Xu Ning had already started sketching designs on a new piece of paper.

Fang Zheng originally wanted to remind this undergraduate team member that such a research topic seemed too profound for him, and it would be better to start with more basic problems.

However, recalling the extraordinary talent Yao Meiling displayed when she joined the team two years ago, and then looking at Xu Ning in front of him.

Although not yet completely confirmed, Fang Zheng was almost certain that the novel idea about the flutter phenomenon earlier came from Xu Ning, which meant his potential even exceeded Yao Meiling's.

So, Fang Zheng chose to remain silent: "I really don't understand you geniuses!" he sighed silently in his heart.

At this moment, Xu Ning turned around and asked: "Senior Brother, what did you just want to say?"

Fang Zheng smiled and didn't answer, just stood silently aside, watching the work in Xu Ning's hands.

"Hey, can you finish your graduation R&D on time?" Fang Zheng asked.

Although the college gave a whole year, in reality, excluding the winter break and the initial exploration phase, the truly available time was only four or five months.

Most team members would choose projects that could be completed quickly.

"This is not my graduation R&D." Xu Ning replied.

"What?" Fang Zheng was even more confused.

Even a talented team member like Yao Meiling took more than five months to complete her graduation R&D back then.

No matter how smart you are, some skills and experience require time to accumulate.

Fang Zheng noticed that Xu Ning was not very skilled when operating the experimental equipment, so he believed he was someone with rich theoretical knowledge but insufficient practical experience.
