Chapter 12 Money-making ability is also very important
Chang Haonan’s major actually didn’t have many classes by the second semester of his junior year, so even though the next day was a Monday, he still had half a day free in the afternoon. .
Zhou Shuwan and Zhang Man even skipped the morning lesson and calculated the design plan corresponding to the half-cone angle of the first precursor in the library, so after class , Chang Haonan went to the cafeteria to grab a few bites of food and then went straight to the computer room with the calculation results and the student ID cards of four people.
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 of this era, especially the fifth step of the design work, which is to generate the internal profile of the inlet. Needs to be done entirely by 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.
And 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. It would be full if only two of the project files were stored.
"When I have resources in the future, I must get the USB disk 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 at another dining table not far from them. Project progress matters.
Although she was hit by Chang Haonan last night and had doubts about her life, 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 to borrow it today. I read some books about DAMP language and dipole grid method, and found some information on the Internet. 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 constantly revising the method, the accuracy has actually been continuously improved. When the project time was already over half, we rashly started over from scratch..."
"Fang Bo, we all know very well, and we will continue to make minor repairs according to the original idea. Xiaobu has no future." Yao Mengna put her chopsticks on the plate and raised her head to look at the boy named Fang Zhen in front of her.
“Although the accuracy is improved by 15-20% compared with the initial result, it can indeed be used to solve the problem, but such a large amount of calculation requires manual parameter adjustment and calibration for each calculation example, which is essentially Shooting an arrow first and then drawing a target has no guiding significance for engineering practice. As scientific researchers, we should not be satisfied with this, especially now that I am 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, let alone senior brother, even when facing mentor Yao Mengna, she 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 pile of books from the library today. "
Compared to the two Ph.D.s Fang Zhen and Yao Mengna, this girl named Xia Tian is only a first-year master's student. It doesn't matter which technical route she takes. It's not important. The top priority is to stabilize the two pillars of the team and never let them get angry.
However, this casual question directly stunned Yao Mengna.
"Yes...I asked it from a senior, who happened to have done a similar project before." Yao Mengna took a deep breath and touched the tip of her nose as she answered.
Originally, Yao Mengna was not a face-conscious person, so it was okay to say that she heard it from her junior students. 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 unable to look back.
"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. The research groups in the college all know each other to a certain extent.
"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 asked 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. "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. It would be better if the new method can work."
Because of Du Yishan. He has a lot to do every day and 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 Ph.D.s. Therefore, as the senior brother, Fang Zhen has to bear a part of the responsibility in addition to scientific research. Management responsibilities make 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 and start preparing to write the manuscript.
On the third day there was still nothing.
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 was shocked when he looked 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.
IBM701C is almost a collectible model in later generations. If you want to buy it at this time, it is estimated to cost tens of thousands of yuan.
Tens of thousands of dollars in 1996!
“When I was running a business, I met a senior from Huaxia Renmin University. He was a senior this year. He opened a restaurant outside and suffered huge losses, so he gave me computer processing to withdraw funds. In the past two days, I asked him Install the two software you used."
The story Wu Yifan told Chang Haonan seemed a bit familiar, but he no longer cared about thinking about it. He quickly took out his laptop and took out the computer. Two floppy disks containing project files.
Open the liver!
