Chapter 12 Money making ability is also very important

Chang Haonan's major actually didn't have many classes in the second semester of his junior year, so although the next day was a Monday, he still had half a day free in the afternoon.

Zhou Shuwan and Zhang Man even skipped a lesson in the morning and calculated the design plan corresponding to the half-cone angle of the first precursor in the library. Therefore, after class, Chang Haonan went to the cafeteria for a simple After eating two mouthfuls of food, I took the calculation results and the student ID cards of four people and went straight to the computer room.

However, things did not go as smoothly as Chang Haonan imagined.

The next task is not difficult for him, but it is not easy for computers in this era. Especially the fifth step of the design work, which is to generate the internal profile of the air inlet, needs to be completely done by the computer. .

Therefore, after he spent 4 hours on the machine today, he finally built the nose model of the first plan, without even having time to combine it with the fuselage.

Moreover, the capacity of the two floppy disks that Yao Mengna lent them was already running low. After all, the capacity of each disk was only 2.88MB, and two of the project files would be full.

"When I have resources in the future, I must get the USB flash drive out in advance. It's so troublesome..." Chang Haonan, who was politely asked out of the computer room by the management teacher, shook his head and thought to himself.

While having dinner in the cafeteria, Chang Haonan told the other three people about the situation.

There is no problem in completing it before the deadline, but Zhang Man and Zhou Shuwan don’t have to work so hard.

Accordingly, considering that the time from completion of the design plan to delivery is very short, Wu Yifan, who is responsible for the text, needs to start in advance and complete the design work in parallel with Chang Haonan.

Of course, the latter has the final say on what to write and how to write. Wu Yifan only needs to be a ruthless writing and drawing machine.

……

While Chang Haonan was eating and assigning tasks, Yao Mengna was also chatting with two classmates in her laboratory about the progress of the project at another dining table not far from them.

Although Chang Haonan made her doubt her life last night, as a doctor, her first reaction after encountering a problem she didn't know was of course not to give up, so she went to the library today to borrow some information about the DAMP language and Occasionally. I also looked for some information on the Internet about the book on the pole grid method. Although it is definitely impossible to fully understand it in one day, I can at least confirm that this idea is worth trying.

"Dipole grid method..." Sitting opposite Yao Mengna was a well-mannered boy with thick hair that didn't look like a doctor: "Junior sister, are you really sure? Although the CFD/CSD coupling method we used before was very inefficient, But after continuous revision of methods, the accuracy has actually been continuously improved, and when the project time was already more than half, it was rashly overthrown and started over..."

"Fang Bo, we all know very well that there is no future in continuing to make small repairs according to the original idea." Yao Mengna put her chopsticks on the dinner plate, raised her head and looked at the boy named Fang Zhen in front of her.

“Although the accuracy is improved by 15-20% compared to the initial result, which can indeed be used to solve the problem, such a large amount of calculation requires manual parameter adjustment and calibration for each calculation example. In essence, it is to shoot the arrow first and then draw the target. It has no guiding significance for engineering practice. As scientific researchers, we should not be satisfied with this, especially now that I am very sure that the dipole grid method is feasible, but we just need to learn some new things."

Although Fang Zhen, a third-year Ph.D. student, looks to be only one year older than Yao Mengna, a second-year Ph.D. student, the latter skipped the master's stage and studied directly for a doctorate, so Fang Zhen is actually much older.

However, when it comes to matters related to research, not to mention senior fellow students, even when facing mentor Yao Mengna, they will never give in easily.

Seeing such a posture, another short and thin girl next to him quickly changed the topic: "Speaking of which, Senior Sister Yao, how did you suddenly come up with this new idea? I have never heard you say it before, just look at you I brought back a bunch of books from the library today."

Compared with the two Ph.D.s Fang Zhen and Yao Mengna, the girl named Xia Tian is only a first-year master's student. It doesn't matter which technical route she takes. The top priority is to stabilize the two pillars of the team. They must not be allowed to get angry.

However, this casual question immediately stunned Yao Mengna.

"Yes... I asked about it from a senior, who happened to have done a similar project before." Yao Mengna took a deep breath, touched the tip of her nose and replied.

Originally, Yao Mengna was not a face-conscious person, so it didn't matter that she heard it from her junior classmate.

But firstly, this doesn’t seem convincing enough, and secondly...

Chang Haonan's tone, like that of a teacher treating a primary school student, really made her unbearable.

"Senior? Are there other research groups in our school working on similar projects?" Fang Zhen was also stunned. You must know that in these days, even undergraduates are rare, and the number of graduate students is even less. Between research groups in a college They all know each other more or less.

"Oh, he was my senior when I was an undergraduate. He is no longer with Beijing Airlines." Yao Mengna had to bite the bullet and continue to make up.

Fortunately, neither Fang Zhen nor Xia Tian inquired further about this issue.

"Then let's do this. Junior sister Xia Tian, ​​you can take over the CFD/CSD work. Anyway, Yao Bo and I have already set up the framework for this. All we need to do is follow the steps. The two of us will try to see if we can get through the dipole. This is the grid method." Fang Zhen quickly found a compromise: "This will at least ensure that there will be results by the end of the year that can be used as proof. If the new method can work, that would be even better."

Since Du Yishan has many things to do every day, he is not in school most of the time. The other teachers in the same group are very young and have not even stayed in school as long as these doctors. Therefore, as a senior brother, Fang Zhen has to do more than scientific research. Assuming some management responsibilities makes him appear conservative in many cases.

"Okay, let's do it like this." Yao Mengna nodded, accepting this compromised plan.

Only Xia Tian, ​​who had not yet had time to express her position, was dumbfounded. The situation reversed so quickly that it completely exceeded her imagination.

How come I, a first-year master's student, was assigned to be in charge of CFD/CSD?

The words are divided into two ends, and the matter comes back to one side.

To Chang Haonan's expectation, he did not see Wu Yifan the whole next day. According to the agreement, the latter should go to the computer room to start writing the manuscript.

Still nothing all day long on the third day.

This even made Chang Haonan a little worried. In his impression, although Wu Yifan was not interested in professional content, he would still do what he promised others.

Early on the fourth day, just when Chang Haonan was already hesitating whether to find a counselor or even call the police, Wu Yifan finally appeared.

"Nan Shen, didn't you say before that the computer time and floppy disk storage space were not enough?" Wu Yifan mysteriously took off his schoolbag and put it on the table, then opened the zipper towards Chang Haonan. "I got a laptop and a new box of floppy disks."

Chang Haonan looked shocked at the IBM classic three-color mark in front of him.

He suddenly felt that it was not a bad thing to have such a friend who was obsessed with business and ignored his studies.

"Where did you buy it?" Chang Haonan turned on the computer and saw that the keyboard first split into two parts as the screen opened, and then came together again.

The IBM 701C is almost a collector's model in later generations. If you want to buy it at this time, it is estimated to cost tens of thousands of dollars.

Tens of thousands of dollars in 96!

"When I was running a business, I met a senior from Huaxia Renmin University. He is a senior this year. He opened a restaurant outside and suffered heavy losses, so he used the computer to help me withdraw funds. In the past two days, I asked him to use the two coins you used. The software is installed."

The story Wu Yifan told Chang Haonan seemed a bit familiar, but he no longer had time to think about it. He quickly took out his laptop and took out the two floppy disks containing engineering documents.

Open your liver!
