Chapter 156: Yang Yuan: We have the help of a master!
103 rooms, conference rooms.
“18.7!”
Zhang Binghe's evaluation figures shocked everyone, especially several aerodynamics experts, who have done a lot of research on the equations, and have done hundreds of calculations just by substituting the values, and have also carried out a lot of numerical demonstration work.
But in the end, the wind pressure test was carried out according to the obtained values, and the best evaluation data was only 23.6.
This evaluation value is a comprehensive evaluation of the pressure of each part, there is a detailed calculation system, the standard is to make the parts with high pressure capacity high pressure, let the parts with low pressure low pressure, and finally calculate the comprehensive value.
The lower the value, the better the effect.
If the value can reach zero, the parts of the aircraft will not be subject to any wind resistance.
That, of course, is impossible.
18.7, that's a staggering number.
In contrast, the power design of low-altitude flight of carrier-based aircraft that is preparing for mass production in China is also based on their research results.
In that set of data, the model wind pressure test value is only 24.
Although the goal of their research is to get the wind pressure test evaluation value below 20, and it is better to be able to come up with a few data schemes, everyone knows that it is good to be able to reach below 22.
The aerodynamics experts in the institute have always believed that below 20 is already very desirable, and it is very difficult to achieve it.
Lowering it down 0.1 is very difficult.
Now the 18.7 data has directly appeared, which is really shocking to them.
In addition to being shocked, Yang Yuan took a deep breath and said, "This experiment is very successful, record all the data, and record it in more detail, so that nothing can be left behind." ”
"Also, prepare a new set of data validations tomorrow."
"Everybody's serious! This would be a major breakthrough in our research......"
Many people were busy that night, and by the next morning, they were in good spirits and ready for the second experiment.
The team has been busy.
Soon a second experiment was conducted, and after half an hour of testing, everyone was busy putting together the data.
In the conference room, Zhang Binghe made calculations again, and then announced a number with surprise, "19.5." ”
This number is not as shocking as '18.7', but it is also below 20, which is surprising enough.
Although the assessment values do not reach the level of 18.7, each set of values has its usefulness.
They are a team that does low-altitude flight dynamics research on aircraft, and each study will do several sets of data, and each set of data represents a feasible plan.
This kind of research can provide data scheme support for aircraft design.
If there is only one set of data, it is equivalent to only one choice, which will definitely have a big impact on the aircraft design.
The design of each aircraft will choose different solutions according to different functions.
The study of the dynamics of aircraft low-altitude flight is only one part of the aircraft design, and more solutions are definitely needed, and the evaluation value of 19.5 is larger than that of 18.7, but it is enough to meet the standard.
After completing the second experiment, Yang Yuan immediately said, "We have made two sets of data schemes, and the next step is to do the recording and sorting." ”
"We will strive to sort out both sets of plans before the arrival of the Shencheng Aircraft Station next week!"
"Everyone has worked hard during this time!"
He then nodded to Cui Xunnian and said, "This time, I also want to praise one person, Comrade Cui Xunnian, who decided to ask Professor Wang Hao to help him do research." ”
"Everyone has seen the results, so we do research, sometimes, don't always take it for granted, we can't do it, it doesn't mean that others can't do it!"
He also glanced at Zhang Binghe as he spoke, and then continued, "Xun Nian, you can continue to contact Professor Wang Hao to see what he needs, and you can get more funds." ”
"This time, he has helped a lot, Professor Wang Hao's side, we must build a good relationship......"
……
Wang Hao didn't care about the situation on Cui Xunnian's side at all.
First, he didn't know what research was done over there, but he knew that it was related to the low-altitude flight of the plane, but he didn't know the specifics.
His research is based on mathematics, not applied mathematics, let alone going further to do projects.
In addition, he is very confident in the 'approximate ungrouping' he has calculated.
If Cui Xunnian gets the data, the experimental verification still fails, which can only mean that there is a problem with the system of equations given at the beginning, not his calculation problem.
On this day, Wang Hao received a letter of thanks, which was sent by Cui Xunnian, because the experiment involved confidentiality, and did not mention much related content, just talked about two sets of data, which helped them a lot in their research.
Wang Hao simply typed a few words, "It's good to be helpful." He thought for a moment and added a few more words, "There are four more sets of data, in a few days, it's been a bit busy lately." ”
He's really busy.
The system of equations given by Cui Xunnian is very complex, and it takes a lot of time to study several sets of approximate solutions.
The further transformation and approximation of each group of approximate degrouping is a very difficult analysis and calculation, and it is not an exaggeration to say that it is equivalent to doing a small study alone.
Wang Hao is not specifically aimed at doing research, he just uses this system of equations as an example to study a new method of 'one step closer approximation'.
This research is almost complete, and the difference is just a summary, so the continued calculation of the system of equations is a repetitive work for him, not a study.
The other party gave a fee of 200,000 yuan, Wang Hao will definitely solve the problem, but he doesn't need to solve it all in one go, take his time, do a little bit when he has time, and then send the value over after he finishes it.
Wang Hao is indeed a little busy, mainly because of the new laboratory.
The main building of the Mason Mathematical Science Laboratory has not yet been built, and it is estimated that it will take at least one year to add decoration and equipment, so the laboratory decided to temporarily open it on the fourth floor of the computer laboratory building.
Even if it is temporarily set up in the laboratory building, it must go through a simple renovation and add certain equipment.
Zhang Zhiqiang is in charge of this work, he has been busy coming and going, and finally announced on this day that the Mason Digital Science Laboratory can be opened.
"I'll take you to see the director's office, it's super luxurious!"
Zhang Zhiqiang said a little proudly.
Wang Hao is also very interested, and the director's office is his office.
When I got to the fourth floor of the laboratory building, I saw the big sign of the Mason Mathematics Science Laboratory, and then walked to the innermost, and there was a room marked 'Director's Office'.
Wang Hao pushed the door in and took a look, and found that it was the same as Zhang Zhiqiang's description, it was indeed 'super luxurious'.
Solid wood embedded in the wallpaper combination of the wall, a high-grade table and chairs at a glance, plus a large sofa, a whole row of bookshelves, a delicate small coffee table, as well as a refrigerator, a coffee machine, a separate bathroom, and a bedroom with a double bed, you can live in it without coming out.
"It used to be a classroom, and it was a big area, so it was separated." Zhang Zhiqiang said a little proudly, "When I was decorating, I ran several times and let them do it." ”
Wang Hao nodded with satisfaction and sighed from the bottom of his heart, "Brother Zhang, thank you." ”
"You're welcome ......"
Zhang Zhiqiang thought about it carefully, and suddenly felt that something was wrong.
What's so complacent about this?
After running hard several times, the office was for Wang Hao, and his office was next door, and it was a double room.
Zhang Zhiqiang went to his office for a turn, and the decoration was also very good, but it hurt a lot when compared to it.
Now the Mason Mathematics Science Laboratory has only just been established, and there are only three official members of the laboratory.
Wang Hao is the chief researcher, Zhang Zhiqiang is the associate researcher, and there is another associate researcher, Zheng Yaojun.
Zheng Yaojun is a very good professor of mathematics at Xihai University, but he did not have a named teaching and research department, so he simply entered the Mason Number Laboratory, Wang Hao also felt that Zheng Yaojun's level was good, in addition, the laboratory has just been established, and there is no harm in having multiple associate researchers, and it can also make the laboratory lively.
One more researcher is not just one more person, it will also have more students under the researcher.
Wang Hao and Zhang Zhiqiang stayed in the laboratory, there were only the two of them at first, and then there were more people.
Wang Hao told the students that they can also come to the laboratory in the future, and there is a graduate student's workshop on the very side, which is also equivalent to an office.
Several people came over to take a look, and they all picked a place for themselves.
In the afternoon, Zheng Yaojun also came.
Zheng Yaojun came with his students, two doctoral students, and one graduate student, Hu Lidan.
Zheng Yaojun came here for the first time, and he was very satisfied with the environment in the laboratory, so he chose the mathematical research office opposite.
During the tour of the laboratory with Wang Hao, I passed by the students' workshops.
Zheng Yaojun glanced inside, and then whispered to Wang Hao, "Hu Lidan, this student, is really excellent. I found that she is the kind of student who is very knowledgeable, and she chases me after class every time to ask questions, and some questions can make me want to go for a long time. ”
Wang Hao listened.
Zheng Yaojun continued with some pride, "She followed me for graduate school, and then followed me for a doctorate, with her talent, she will definitely be very good in the future." ”
"In another two years, she may be able to complete the research herself, and she may be able to complete very good results in the direction of partial differential equations."
"Didn't you just attend the math club? I think she will be able to complete her doctoral dissertation at the level of the Zhong Jiaqing Mathematics Award in the future, and it would be a ...... if the student could win such an award."
Zheng Yaojun laughed as he spoke.
Wang Hao pouted when he heard this, and the graduate student had just brought it up, and he began to think about the Zhong Jiaqing Mathematics Award?
Why don't you think about it when you are doing your PhD?
At this time, Helen also came over, and she asked Wang Haodao, "Teacher Wang, where is the workshop?" ”
"Over there."
Wang Hao pointed in a direction, "Chen Mengmeng is also there, and there are other students." He added, "Helen, if you talk to other people more, you can also improve your Chinese skills." ”
"I see."
Helen said and was about to walk away.
Zheng Yaojun suddenly spoke, "I remembered!" ”
Helen suddenly stopped and looked over.
Zheng Yaojun pointed at Helen and said, "I'll just say, you look familiar, and you also take my class, right?" It turns out that you are Wang Hao's student. ”
He said, "But I found that you never ask questions, and you leave every time you finish class, I thought your Chinese was not good, and now it doesn't seem bad!" ”
"But it doesn't matter, even if you ask a question in English, I can answer it, and my English is not bad."
"In this regard, you have to learn more from Hu Lidan!"
Wang Hao was shocked when he heard this.
He wondered why Zheng Yaojun suddenly talked about this, it turned out to be a routine, going around and talking about his students!
This is to compare Helen to Hu Lidan, and then show that his students are better than my students?
However, comparing Helen to the wrong person, right?
Helen listened to Zheng Yaojun's words, her face was obviously a little confused, and she suddenly asked, "Why do you want to ask?" ”
Zheng Yaojun said, "If students have questions, they should ask the teacher, and ask more questions in order to have a deeper understanding of the basics, and the difficulty of the course of differential equations ......."
Helen interrupted him with some confusion, "However, I don't feel the difficulty, the content of your class is very simple. ”
She stared at Zheng Yaojun, thought about it carefully, and then suddenly said, "Is it because of social etiquette, right?" It must be social etiquette, even if there is no doubt, ask the teacher questions. In this way, the teacher can have a sense of accomplishment of intellectual superiority. ”
"That's right, right?"
Helen found that Zheng Yaojun did not refute, and nodded, "In this way, I will understand, in the next class, I will definitely prepare the questions first." ”
After she finished speaking, she seemed to have a sense of joy that she had learned something new, and jumped out of the room.
"Uh~~"
Zheng Yaojun was dumbfounded when he listened, I asked her to ask questions, in order to give me a sense of accomplishment of intellectual superiority?
Is that so?
Zheng Yaojun didn't say anything for a long time, and finally looked at Wang Hao in a daze, "...... What does she mean. ”
"You hear me."
Wang Hao held back a smile and spread his hands helplessly.
On the other side, the student workshop.
Hu Lidan was talking to Chen Mengmeng, "Will Mr. Wang recruit doctors in the future?" I've already thought about it, and I'll apply for Mr. Wang's Ph.D. when I finish my graduate school. ”
"I don't know." Chen Mengmeng shook her head.
Hu Lidan whispered depressedly, "Meng Meng, let me tell you, in fact, at the beginning, I thought it was not bad to study with Teacher Zheng, go to graduate school, and then study for a doctorate...... But his mouth, my God...... I really can't stand it, and I feel ashamed everywhere I go. ”
Helen walked in and said, "I think your teacher is very good. ”
"Huh?" Hu Lidan was stunned for a moment.
Helen said seriously, "He's very sociable. She walked to the back row and found a spot.
Hu Lidan asked Chen Mengmeng with doubts, "Is she sarcastic?" ”
Chen Mengmeng looked at Helen, rubbed her forehead vigorously, and said with certainty, "When you can't see her emotions, what he says is what he says." ”
"So, she must have thought so."
"But, Mr. Zheng, are you good at socializing? How the hell did she judge? ”
Hu Lidan couldn't figure it out at all.
……
The Mason Digital Science Laboratory was officially opened.
Wang Hao has a new office, which is really fresh for several days, and the frustrating thing is that 'it is too close to the students', and there are always students who come to ask questions.
If for the sake of teaching, it is not bad to be able to answer students' questions all the time, which will definitely improve the students a lot, but it will delay their own research.
Later, he simply hung a 'Do Not Disturb' sign at the door.
All of a sudden, it was quiet.
Wang Hao also patiently completed the numerical work of the remaining four groups of approximate solutions to the equation given by Cui Xunnian.
This work took about ten hours, and it still made people feel a little irritated.
"It would be nice if the students could all improve and explain similar work to them, so that they can do it slowly......"
Wang Hao pondered.
That's what he expects from his students.
The other side.
The 103 Institute is busy receiving the team from the Shencheng Aircraft Design and Research Institute, led by the famous fighter designer Li Jianhua.
Li Jianhua led the team to complete the design of several advanced fighters, one of which was manufactured on a large scale.
This time, he led a team to 103 institutes, which is also an investigation of 103 research projects, which can provide a certain data reference for the design of high-end fighters in the future.
Fighter design is not as simple as clothing design, but a systematic and huge project.
The 103 is a low-altitude flight dynamics research, which is a basic research in the fighter design process, which can provide low-altitude flight performance data reference for fighter design.
Fighter designs are all cutting-edge.
Li Jianhua's team is considering the design of the third-generation carrier-based aircraft, which needs to be referred to in all aspects of the data, and he has visited several related research institutes in a row.
103 is just one of them.
However, the research of the 103 Institute is also very important, because the dynamic argument of the shape of the fighter shows that low-altitude flight is much more important than high-altitude flight.
High-altitude flight is just a regular flight, and it is the combat radius that is required, not the maximum speed.
Now conventional fighters can exceed the speed of sound at a maximum speed.
That's enough.
The power and wind resistance of low-altitude flight are directly related to the safety and flexibility of the fighter, which is the most important.
Therefore, Li Jianhua came to the 103 institute and brought the power group of the institute.
The power group of the aircraft design and research institute is still very powerful, and the research involves all aspects of aircraft power, and low-altitude flight is naturally also studied.
They knew that the research of the 103 Institute had encountered problems, and they also came to do exchanges and discussions together.
When a group of people came to the conference room, Li Jianhua said to Yang Yuan, "We came this time, first, to see the progress of your research, and on the other hand, we heard that your research has fallen into a bottleneck, and our power group also has research on the wind pressure problem of low-altitude flight, so let's communicate with you." ”
"I hope that through this exchange, the technology can go further, and I hope that there can be a wind pressure test to evaluate a scheme below 20 in order to support the design needs of higher-end fighters."
Yang Yuan immediately smiled when he heard this, "It's okay to communicate, but in terms of the data plan for low-altitude flight, you don't have to worry." ”
"Oh?" Li Jianhua was a little puzzled when he heard this.
Yang Yuan smiled a little smugly, "We already have two sets of data schemes with an evaluation value of less than 20. ”
"We will continue to study in the future, and I hope to have more solutions."
Li Jianhua was suddenly shocked.
The two powerful experts next to him were also shocked to hear this, and one of them said a little incredulously, "Chief Engineer Yang, you're not joking, are you?" Two scenarios with an assessment data of less than 20? ”
"How did you calculate that? If you rely on experimentation, you're lucky, right? ”
Yang Yuan said proudly, "Of course it's not luck, we have a master to help us!" ”
