However, perhaps because this body did have a serious lack of rest before he was reborn, coupled with an afternoon of sitting and hunger, Chang Haonan, who suddenly stood up, suddenly felt lightheaded, and then the edge of his vision gradually darkened......

Fortunately, Wu Yifan, who was quick-eyed, stretched out his hand to support him from behind: "Haonan, you probably haven't slept much in the past few days, don't be too anxious, there is still a lot of time for course design, don't worry about this day or two." ”

"Brother Nan, go back and rest after eating, and leave things like data mapping and performance analysis to us."

Zhang Man's concerned expression didn't seem to be fake, the four of them were both prosperous and losing as the same course design team, and she was naturally worried about the new thigh she had just hugged.

Moreover, although the latter work is also cumbersome, it is not very technical, and it is not difficult for juniors when there is already data.

As an experienced person with thighs, Zhang Man deeply understands that being in a group with the big guy definitely does not mean that he can do nothing, although it was very easy at the time, there is a high probability that there will be no next time.

On the contrary, if you take the initiative to share some tasks, there is a high probability that you can gain the favor of the top students.

"No, this is the original design data of the MiG-21, I just program the calculation program first and then verify whether it can run through, so that after our design comes out, we can calculate it as long as we modify the model and grid mode slightly."

The few people who spoke had already walked to the next classroom, and Chang Haonan opened the lunch box in his hand and replied without raising his head.

Two meat and one vegetarian with white rice was already a good food condition in the 90s.

Let's not talk about Zhang Man's personality, this kind of white, young and thin type of girl actually doesn't quite match his aesthetics, if you have to say it......

Chang Haonan glanced at Yao Mengna, who was eating quietly opposite.

So he found that only his own box had two meat dishes.

This Zhang Man can only be said to be a little scheming, but not much.

"That's right...... Forget it, eat first. Zhang Man, who knew that he had just behaved in the wrong place, showed a somewhat embarrassed expression on his face, but it returned to its original state in an instant.

"You're going to revise the design of the aircraft later?" Yao Mengna also heard Chang Haonan's words just now, raised her head and asked.

"Yes, this is the big assignment of our aircraft design course, and when Haonan first said that he wanted to design a supersonic fighter, we thought it was unrealistic, but I didn't expect him to be so powerful."

Zhou Shuwan is definitely an honest person, and even praised Chang Haonan in front of his goddess.

After seeing the latter's smooth operation, the other three people no longer had the idea of questioning Chang Haonan's thinking at all.

"I have a lot of ideas, when I first took this course, I designed a transport plane with a lower wing, and I got a perfect score in the end."

Yao Mengna raised her head slightly, as if she was nostalgic for her past undergraduate days: "In fact, according to my experience, as long as you can complete the design process without making mistakes, you can almost get a full score."

Of course, Yao Mengna was just stating a fact, and she didn't mean to boast at all.

In her opinion, for students like Chang Haonan, the full score of course design is just a matter of hand, and it is not worth mentioning at all.

However, the invisible pretending is the most deadly, and this sentence still makes Zhou Shuwan and Wu Yifan look at each other.

After all, if it weren't for Chang Haonan, they really wouldn't dare to say that they could come up with a design that would not make mistakes, even if it was to design the simplest aircraft as Zhou Shuwan said.

"By the way, the school's computer room can't store things, how are Haonan going to bring this program back?" After more than a dozen seconds of silence, Zhou Shuwan brought the topic back to their design project.

Chang Haonan, who has been bowing his head and grilling rice, is sorting out the next step in his mind at this time, because he did not let the system directly give the design results, so after determining the general direction, the specific details still have to be manually optimized.

In fact, it is to make several different designs, and then test their key performance at the design point to see if you can find some rules from them, and then slowly fine-tune them, which are some very empirical operations.

So after hearing Zhou Shuwan's question, Chang Haonan replied almost without thinking: "Which of you brought U ......"

Speaking of which, he realized that something was wrong, where did he get such a thing as a USB flash drive in 1996, so he quickly changed his words: "Which of you brought a floppy disk, our program is not big, just save the engineering files of the model and the code of the CFD simulation to two floppy disks." ”

“……”

The four of them looked at each other speechlessly.

These days, people don't even have their own computers, and few people will spend money to buy a floppy disk as a storage medium.

"I have two empty floppy disks here, I'll lend them to you first." In the end, Yao Mengna spoke: "But remember to return it to me when you finish using it." ”

Chang Haonan took the floppy disk from the other party's hand, and Yao Mengna's name was written on the disk, as well as the college and office where he was located.

"Senior Sister Yao is from Academician Du Yishan's research group?" Zhang Man next to him leaned over and took a look. Then he asked in shock.

"Yes, Academician Du is my mentor." Yao Mengna lifted a few strands of hair hanging down to her forehead to her shoulders and replied lightly, as if it was just a trivial matter.

Zhang Man and Zhou Shuwan's eyes widened almost at the same time.

Academician Du Yishan, as a domestic Taishan Beidou-level figure in the field of aerodynamics, although he is no longer responsible for specific aircraft design projects, the connections and resources behind him should not be underestimated.

In this era of tight research funding, having such a mentor means being exposed to more topics and having many more opportunities than others.

And Yao Mengna is also a student of Du Yishan.

You must know that the students of the academician and the students of the academician's research group sound similar, but in fact they are very different.

Zhou Shuwan, who was already determined to study further due to family reasons, was suddenly full of admiration for this senior sister in his heart, and began to hesitate to ask the other party's research group to recruit students.

And Zhang Man next to him has already begun to think about how to have a good relationship with this senior sister.

Only Chang Haonan and Wu Yifan were completely indifferent to this.

The former is still thinking about how to arrange the next work, after all, each new design has to re-model and calculate the nose module, although most of the code does not need to be rewritten, but it is also a very time-consuming work, and he is not always lucky to meet Yao Mengna in the machine room every time.

As for the latter, he was not interested in his major at all, and he was thinking about a business that he was going to talk about in the next two days, and he didn't even hear the conversation of the other people just now.

After dinner, Chang Haonan waited for a while, let the computer run out all the calculation results, and after receiving the prompt of the system [the project was successfully completed], he copied the files to two floppy disks respectively, and then rubbed his eyes that were a little sore, and breathed a sigh of relief.

On the one hand, the preliminary work is finally completed, and on the other hand, it also proves that the system is ......

It's really awesome!
