The evaluation figures Zhang Binghe said shocked everyone, especially a few aerodynamics experts. They had done a lot of research on the equations and simply substituted the numerical values into hundreds of calculations.
A lot of numerical demonstration work.
But in the end, the wind pressure test was carried out based on the obtained values, and the best evaluation data was only 23.6.
This evaluation value is a comprehensive assessment of the pressure of each part. There is a detailed calculation system. The standard is to allow components with high pressure-bearing capacity to bear high pressure, and to allow components with low pressure-bearing capacity to bear low pressure. Finally, the calculated comprehensive
value.
The lower the number, the better the effect.
If the value can reach zero, each component of the aircraft is equivalent to not receiving any wind resistance.
That is of course impossible.
18.7, this value is really amazing.
For comparison, the low-altitude flight power design of domestic carrier-based aircraft that are preparing for mass production also adopts their research results.
In that set of data, the model wind pressure test value was only 24.
Although their research goal is to reduce the wind pressure test evaluation value to below 20, it is best to come up with several sets of data plans, but everyone knows that it is already very good if it can reach below 22.
The aerodynamics experts in the institute have always believed that below 20 is already a very ideal state, and it is very difficult to achieve it.
It is very difficult to reduce it further by 0.1.
Now the data of 18.7 appeared directly, which really shocked them.
After being shocked, Yang Yuan took a deep breath and said, "This experiment was very successful. Record all the data. We need to record it in more detail and not miss anything."
"Also, prepare a new set of data for verification tomorrow."
"Everyone, get serious! This will be a major breakthrough in our research..."
Many people were busy that night, and in the morning of the next day, they became energetic again and began to prepare for the second experiment.
The team has been busy.
The second experiment was quickly conducted. After half an hour of testing, everyone was busy summarizing the data.
In the conference room, Zhang Binghe did the calculation again, and then announced a number with surprise, "19.5."
This number is not as shocking as '18.7', but it is still a number below 20, which is surprising enough.
Although the evaluation value does not reach the level of 18.7, each set of values has its use.
They are a team that conducts research on aircraft low-altitude flight dynamics. Each study will produce several sets of data, and each set of data represents a feasible solution.
This kind of research can provide data solution support for aircraft design.
If there is only one set of data, it means there is only one choice, which will definitely have a great impact on the aircraft design.
Each aircraft design will choose different solutions based on different functions.
The research on the power of aircraft's low-altitude flight is only one part of aircraft design, and more solutions are definitely needed. The evaluation value of 19.5 is larger than 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 plans, and the next step is to record and organize them."
"We must strive to have both sets of plans sorted out before the arrival of Shencheng Aircraft Station next week!"
"Everyone is working harder during this time!"
He then nodded to Cui Xunnian and said, "This time, I also want to praise someone, Comrade Cui Xunnian, who decided to ask Professor Wang Hao to help with research."
"Everyone has seen the results, so when we do research, sometimes we don't always take it for granted. Just because we can't do it doesn't mean others can't do it!"
He glanced at Zhang Binghe as he spoke, and then continued, "Xunnian, just continue to contact Professor Wang Hao and see what needs he has. You can get more funds."
"This time, he has been of great help. Professor Wang Hao must establish a good relationship..."
…
Wang Hao didn't care about Cui Xunnian's situation at all.
For one thing, he didn't know what kind of research was being done there. He just knew that it was related to low-altitude flight of aircraft, but he didn't know the details.
His research is on basic mathematics, not applied mathematics, let alone further projects.
In addition, he is very confident in the 'approximate solution' he calculated.
If Cui Xunnian gets the data and the experimental verification still fails, it can only mean that there is a problem with the initially given set of equations, not his calculation.
On this day, Wang Hao received a letter of thanks from Cui Xunnian. Because the experiment involved confidentiality, he did not mention the relevant content. He only mentioned two sets of data, which was of great help to their research.
Wang Hao simply typed a few words, "It would be great if it helped." He thought for a while and added a few more words, "There are still four sets of data, in a few days, I'm a little busy recently."
He is indeed very busy.
The system of equations given by Cui Xunnian is very complicated, and it took a lot of time to research several sets of approximate solutions.
The further transformation and approximation of each group of approximate solutions are very difficult to analyze and calculate. It is not an exaggeration to say that it is equivalent to doing a small study alone.
Wang Hao is not specifically doing research. He just uses this system of equations as an example to study a new 'one step approximation' method.
This research is almost complete, and the only difference is the summary. Therefore, continuing to calculate the system of equations is a repetitive work for him, rather than research.
The other party gave Wang Hao a fee of 200,000. He will definitely solve the problem, but he doesn't need to solve it all at once. He can do it slowly and when he has time, and then send the values after he is done.
Wang Hao is indeed a little busy, mainly with the new laboratory.
The main building of the Mason Mathematical Sciences Laboratory has not yet been built, and it is estimated that it will take at least one year to complete the decoration, equipment transportation, etc., so the laboratory decided to temporarily open on the fourth floor of the computer laboratory building.
Even if it is temporarily opened in a laboratory building, it will definitely need to undergo some simple decoration and purchase certain equipment.
Zhang Zhiqiang is responsible for this work. He has been busy and busy, and finally announced on this day that the Mason Mathematical Science Laboratory can be opened.
"I'll take you to see the director's office. It's super luxurious inside!"
Zhang Zhiqiang said with some pride.
Wang Hao is also very interested, and the director's office is his office.
When we arrived on the fourth floor of the laboratory building, we saw the big sign of the Mason Mathematical Science Laboratory. Then we walked to the very back and there was a room labeled 'Director's Office'.
Wang Hao opened the door and took a look, and found that it was indeed 'super luxurious' just as Zhang Zhiqiang described.
Solid wood embedded in the wall combined with wallpaper, tables and chairs that look very high-grade at first glance, plus a large sofa, a whole row of bookshelves, an exquisite small coffee table, a refrigerator, a coffee machine, a separate bathroom, and a partition
There is a bedroom with a double bed inside, so you can stay in it without leaving.
"This used to be a classroom, and it was very large, so it was separated like this." Zhang Zhiqiang said with some pride, "During the renovation, I made several trips to let them do this."
Wang Hao nodded with satisfaction and sighed from the bottom of his heart, "Brother Zhang, thank you."
"You're welcome……"
Zhang Zhiqiang thought carefully and suddenly felt something was wrong.
What's so proud about this?
After a lot of hard work, it turned out that the pretend office was for Wang Hao, but his office was next door, and it was a double room.
Zhang Zhiqiang took a look around his own office. The decoration was also very good, but in comparison, it felt very harmful.
Now the Mason Mathematical Science Laboratory has 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 an excellent mathematics professor at Xihai University, but he did not name himself as a teaching and research department, so he simply entered the Mason Mathematics Laboratory. Wang Hao also thinks that Zheng Yaojun’s level is good. In addition, the laboratory has just been established, so there is no harm in having multiple associate researchers.
The laboratory is a bit lively.
One more researcher is not only one more person, but also more students under the researcher.
Wang Hao and Zhang Zhiqiang stayed in the laboratory. At first it was just the two of them, but later more people came.
Wang Hao told the students that they would be able to come to the laboratory in the future, and there would be a graduate student's studio at the end, which is also equivalent to an office.
Several people came over to take a look and picked a spot for themselves.
In the afternoon, Zheng Yaojun also came.
Zheng Yaojun came with his students, including two doctoral students and a graduate student, Hu Lidan.
This was Zheng Yaojun's first time here. He was very satisfied with the environment of the laboratory, so he chose the mathematics research office opposite.
During the visit to the laboratory with Wang Hao, we passed by the student's workshop.
Zheng Yaojun glanced inside, and then whispered to Wang Hao, "Hu Lidan is such an outstanding student. I found that she is the kind of student who is very serious about knowledge. She chases me after every class to ask questions, and some
These questions can keep me thinking for a long time.”
Wang Hao listened.
Zheng Yaojun continued with some pride, "She studied with me for graduate school, and then studied for a Ph.D. with me. With her talent, she will definitely be very good in the future."
"In another two years, she may be able to complete her own research, and she may be able to achieve excellent results in the direction of partial differential equations."
"Didn't you just join the Mathematics Society? I think she can complete a doctoral thesis at the level of the Zhong Jiaqing Mathematics Award in the future. If a student can win such an award, it would be really..."
Zheng Yaojun laughed happily as he spoke.
Wang Hao curled his lips when he heard this. The graduate student had just brought him up and started thinking about the Zhong Jiaqing Mathematics Award?
Why don’t you think about it when you’re studying for a Ph.D.?
At this time, Helen also came over. She asked Wang Hao, "Teacher Wang, where is the workshop?"
"there."
Wang Hao pointed in one direction, "Chen Mengmeng is here, and there are other students." He added, "Helen, you can improve your Chinese by talking to other people more."
"I see."
Helen said and was about to walk away.
Zheng Yaojun suddenly said, "I remembered!"
Helen suddenly stopped and looked over.
Zheng Yaojun pointed at Helen and said, "I just said, you look familiar. You also take my class, right? It turns out you are Wang Hao's student."
He said, "But I found that you never asked questions and left every time after class. I thought your Chinese was not good, but now it seems that it is not bad either!"
"But it doesn't matter. Even if you ask questions in English, I can answer them. My English is not bad either."
"In this regard, you should learn more from classmate Hu Lidan!"
Wang Hao was shocked when he heard this.
He was wondering why Zheng Yaojun suddenly mentioned this. It turned out to be a routine. After going around and around, he still talked about his students!
This is to compare Helen and Hu Lidan, and then prove that his students are better than my students?
However, if you compare it with Helen, you are looking at the wrong person, right?
After hearing what Zheng Yaojun said, Helen's face was obviously confused, and she immediately asked, "Why are you asking?"
Zheng Yaojun said, "If students have questions, they should ask the teacher. Only by asking more questions can they have a deeper understanding of the basics. The difficulty of the differential equations course..."
Helen interrupted him with some confusion, "But, I didn't feel the difficulty. The content you taught in class was 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 you have no questions, you still have to ask the teacher questions. This can make the teacher feel that he has superior knowledge.
A sense of accomplishment.”
"That's it, right?"
Helen noticed that Zheng Yaojun did not refute, so she nodded and said, "This way, I understand. I will definitely prepare questions for the next class."
After she finished speaking, she seemed to feel a sense of joy that she had "learned new knowledge" and walked out jumping up and down.
"Uh~~"
Zheng Yaojun was dumbfounded. I asked her to ask questions to give me a sense of accomplishment with superior knowledge?
Is that so?
Zheng Yaojun didn't say anything for a long time, and finally looked at Wang Hao blankly, "...What does she mean?"
"You heard me."
Wang Hao suppressed his laughter and spread his hands helplessly.
On the other side, the student workroom.
Hu Lidan was talking to Chen Mengmeng, "Will Teacher Wang recruit Ph.D. students in the future? I have already thought about it. I will apply for Teacher Wang's Ph.D. after I finish graduate school."
"I don't know." Chen Mengmeng shook his head.
Hu Lidan whispered depressedly, "Meng Meng, let me tell you, in fact, at the beginning, I thought it would be good to study with Teacher Zheng, go to graduate school, and then study for a Ph.D.... But his mouth, my god... it's really annoying
No, I feel embarrassed wherever I go."
Helen was walking in and immediately said, "I think your teacher is very good."
"Ah?" Hu Lidan was stunned for a moment.
Helen said seriously, "He is very sociable." After that, she walked to the back row and found a seat.
Hu Lidan asked Chen Mengmeng with doubts, "Is she being sarcastic?"
Chen Mengmeng looked at Helen, rubbed her forehead vigorously, and said with certainty, "When you can't see her emotions, he is speaking from his heart."
"So, she must think so."
"But, Teacher Zheng, is she good at socializing? How does she judge?"
Hu Lidan couldn't understand it at all.
…
Mason Mathematical Sciences Laboratory was officially opened.
Wang Hao has a new office, which has been really new for several days. What is frustrating is that it is "too close to students" and students always come to ask questions.
For teaching reasons, it would be nice to be able to answer students' questions all the time. It will definitely make students improve a lot, but it will delay their own research.
Later, he simply hung a 'Do Not Disturb' sign on the door.
All of a sudden, it was quiet.
Wang Hao also patiently completed the numerical work on the remaining four sets of approximate solutions to the equations given by Cui Xunnian.
This work took about ten hours, and it still made people feel a little irritated.
"It would be great if the students could all improve. Explain similar work to them and let them do it slowly..."
Wang Hao thought.
This is his greatest expectation for his students.
the other side.
Institute 103 is busy receiving a team from the Shencheng Aircraft Design Institute. The team is led by the famous fighter jet designer Li Jianhua.
Li Jianhua has led a team to complete the design of several advanced fighter aircraft, one of which has been mass-produced.
This time I led a team to the 103rd Institute to inspect the research projects of the 103rd Institute, which can provide certain data reference for the design of future high-end fighter aircraft.
Fighter design is not as simple as clothing design, but a systematic and huge project.
What 103 is doing is low-altitude flight dynamics research, which is a basic research in the design process of fighter aircraft and can provide data reference for low-altitude flight performance for fighter design.
Fighter aircraft designs are all cutting-edge.
Li Jianhua's team is considering demonstrating the design plan of the third-generation carrier-based aircraft, which requires reference from all aspects of data. He went to several related research institutes in succession.
103 schools, just one of them.
However, the research conducted by the 103 Institute is also very important, because in terms of power demonstration of fighter aircraft shape, low-altitude flight is much more important than high-altitude flight.
High-altitude flight is just conventional flight. The most important requirement is the combat radius, not the maximum speed.
Nowadays, the maximum speed of conventional fighter planes can exceed the speed of sound.
that's enough.
The power and wind resistance of low-altitude flight are directly related to the safety and flexibility of the fighter aircraft, and are the most important.
So Li Jianhua came to Institute 103 and brought the institute’s power team with him.
The power group of the Aircraft Design Institute is still very powerful, and its research involves all aspects of aircraft power, including low-altitude flight.
They knew that the research at Institute 103 had encountered problems, and they came over to have exchanges and discussions.
When a group of people arrived in the conference room, Li Jianhua said to Yang Yuan, "We are here this time. One is to see the progress of your research. The other is that we heard that your research has reached a bottleneck. Our power unit is flying at low altitude."
We have also conducted research on the issue of wind pressure and would like to share with you.”
"I hope that through this exchange, the technology can be further advanced. I hope that there will be a solution with a wind pressure experimental evaluation of less than 20, so as to support the design needs of higher-end fighter aircraft."
After hearing this, Yang Yuan immediately smiled and said, "Communication is possible, but you don't have to worry about the data plan for low-altitude flight."
"Oh?" Li Jianhua sounded a little confused.
Yang Yuan smiled complacently and said, "We already have two sets of data plans with evaluation values below 20."
"We will continue to study and hope to have more plans."
Li Jianhua was immediately shocked.
The two highly motivated experts nearby were also shocked. One of them said incredulously, "General Manager Yang, are you kidding me? Two sets of plans with evaluation data below 20?"
"How did you calculate it? If you relied on experiments, you would be lucky, right?"
Yang Yuan said proudly, "Of course it's not luck, we have experts to help us!"
