Chapter 195: The great result is released, Wang Hao: It is the most perfect airplane!
Love is priceless.
In the face of love that cannot be measured by money, what does an expensive villa mean?
Wang Hao felt that the reasons he thought of were very convincing, so he continued to persuade Zhang Zhiqiang a few words, and then happily looked forward to the villa he was awarded.
In the city center, Guangxian Mansion, more than 250 square meters, is most likely to be finely decorated.
Perfect!
Let Zhang Zhiqiang enjoy the priceless luxury of love. He can just enjoy a low-end large villa.
With security and villas, life becomes better.
Wang Hao felt really relaxed for a while. Even though he had some inspiration, he did not continue his research.
People are not machines, they still need to rest when they should.
Wang Hao instructs students in the Mason Tree Laboratory, occasionally gives lectures in the classroom, and also holds small classes in the laboratory. The leisurely life makes people intoxicated.
But research still needs to be done.
Wang Hao occasionally uses his brain to think of new research and development ideas. The main idea lies in the study of NS equations. In fact, the reason why he continues to study the 'trajectory correction of random three-dimensional curve functions' is to find the complete NS equation.
Inspiration for the direction of the equation.
After completing relevant research, he also knew the follow-up direction of NS equation research.
That has to do with computational logic.
In the previous research on NS equations, there are special approximate solutions for partial differential equations, and more approximate approximate solutions can be solved. The limitation lies here.
An approximation is always an approximation.
Even if there is a special system of partial differential equations that has an exact solution, it is impossible to find the exact solution through that kind of analysis method.
That is just an analytical method for approximate solutions, and is not consistent with the actual solution.
Wang Hao completed the research on "parameter calculation logic" through complex demonstrations with Luo Dayong, and can follow this idea to solve partial differential equations in a more refined manner.
The original method was to find approximate solutions through analytical substitution. Now that we have clarified the calculation logic of the partial differential equations, we can find the 'infinitely extended applicable solution set'. We can use the numerical substitution method as a breakthrough and rely on computational logic analysis to find the solution.
'Optimal ungrouping'.
For example, a system of partial differential equations has four parameters, two of which can provide exact solutions, and two of which can only provide approximate solutions.
This method can clearly find the exact solution and make the other two more approximate.
Of course, having an exact solution is a special case.
In most cases, there is no exact solution, so you can use numerical methods to identify the solution to one of the unknowns, and then analyze and calculate the correlation to find other solutions with high approximation.
This solution method will be more approximate than the original method. If an exact solution can be obtained, the exact solution can also be obtained by substitution.
"Carry out analysis through infinite extension, and then find the corresponding applicable solution set."
"This will make the solution set clearer and more precise, and lead to a more approximate solution set."
"But what's the use?"
After Wang Hao made the summary, he couldn't help but think about the application problem. The method he used can indeed obtain a more accurate solution, but the corresponding calculation and analysis is greatly difficult.
If other scholars want to use the same method for analysis, the threshold for understanding the method is already very high, and they need to master a lot of cross-field knowledge.
Even if you have mastered the solution method, it will take a long time to find a set of solutions.
"If you're talented, maybe a week?"
"For worse ones, it may take a few months..." Wang Hao thought a little uncertainly, but judging from the content, even Professor Zhou Qingyuan's level must be classified as "poor talent".
This kind of judgment of poor talent is mainly due to not being good at 'complex analysis', and it is impossible to be proficient in using complex analysis methods.
At the same time, scholars who are good at analysis may not necessarily be proficient in partial differential equations.
Not to mention, it also involves knowledge of functional analysis, computational mathematics, etc. The threshold is already so high that most mathematicians are excluded.
This calculation method is so difficult that it is almost impossible to cover the application.
First, it is impossible to use computers for analysis.
The second is that the analysis is done manually and the requirements for scholars are too high.
In addition, even if a more accurate solution can be obtained, it seems to be of little significance.
For example, aircraft shape design.
There are too many things to consider in appearance design, and it is impossible to specifically change the direction and size of the wings or other parts just for "more accurate calculations."
For this kind of direct application design, ordinary approximate solution is sufficient.
"So, this research is meaningless?"
"But it is impossible to publish it." Even if the application direction cannot be thought of for the time being, because the solution of NS equations is directly related to its application, non-theoretical content cannot be published directly.
This made Wang Hao very embarrassed.
He always felt that it was too wasteful to just write a paper and then submit it for confidential filing.
Even if it is confidentially archived, not many people will look at such difficult content. Maybe after confidentially archived, the paper will always be in a confidential document, and no one will be able to grasp the content for decades.
"Otherwise, I can design an airplane myself?"
"Calculate yourself, design by yourself, and design to the most perfect state in theory, which can minimize resistance and increase upward thrust. With the same power, you can fly farther..."
"It makes sense!"
Wang Hao's eyes suddenly lit up as he thought about it.
After he simply drew a picture, he immediately immersed himself in calculations.
Zhang Zhiqiang opened the door and walked in. He saw Wang Hao busy and waited for a while. It wasn't until Wang Hao raised his head that he asked, "Didn't I disturb you?"
"It doesn't matter."
Wang Hao said nonchalantly, "I'm just designing something."
"Design what?"
"airplane."
Zhang Zhiqiang was stunned for a moment with confusion on his face. He glanced at the things on the table and found that they were all a lot of complex mathematical calculations, with a simple airplane drawn next to it?
Is it really a plane?
He thought he heard something absolutely confidential, so he quickly covered his mouth and even his ears. He took several steps back before saying, "I didn't hear anything. I don't know.
do not know anything."
Wang Hao looked at him strangely and asked, "Is something wrong?"
"Is such that."
Only then did Zhang Zhiqiang remember the purpose of coming here, "Didn't you say last time that there was an eight-million-dollar project? A project with Wuhan Iron and Steel Co., Ltd.? How's it going? The program for our cooperation with the Space Administration has been debugged, and the follow-up is
Make modifications, finish it, and then wait for the space agency to dock it."
"In the past two days, I have been feeling idle." He continued with a sigh, "I am a person who feels uncomfortable all over once I become idle."
Wang Hao was stunned when he heard this. He asked strangely, "Really or not? Do you feel uncomfortable when you are idle?"
He walked over and looked Zhang Zhiqiang up and down and gave him a suggestion, "How about this? When I went to the office in the morning, Zhu Ping also said that there was a lot of homework to be marked. Can you go and help her mark the homework?"
"Also, the workers in the newly built building of our laboratory are busy, so you should follow suit. Also, I see that several doctoral students are working very hard, so go and buy lunch for them."
Zhang Zhiqiang grinned hard after hearing this, and held back a sentence for a long time, "You think I'm sick!"
Wang Hao laughed.
Of course he knew what Zhang Zhiqiang meant. He just wanted to do more projects and get more labor fees. Cooperation with Wuhan Iron and Steel was Wang Hao's personal project. If he found other people to do it together, he would naturally have to pay more labor fees.
Wang Hao sat back and said, "Brother Zhang, don't worry about that project yet. Just wait until I finish the work in hand. If you wait a little longer, if I really want to find someone to help with the project, I will definitely come to you."
"Then say it in advance, but don't tell Professor Qi, that guy always..."
"Ahem."
Professor Qi Xiao stood at the door and coughed, glanced at Zhang Zhiqiang angrily, then snorted and said to Wang Hao, "I just debugged the program and there was no problem. Should I ask the space agency to do the docking in advance?"
Wang Hao nodded and said, "Then let me talk to them."
Qi Xiao glanced at Zhang Zhiqiang again and snorted again in annoyance.
Zhang Zhiqiang suddenly became even more embarrassed.
…
at the same time.
Institute 137 welcomed Academician Zhao Xingli, the general manager of the three aerospace industry regions, and was accompanied by several professors, including leaders of the two military regions.
The group came to 137 Institute for inspection.
In recent months, they have been constantly visiting their research institutions to learn about the latest research progress.
After understanding all the information, we can comprehensively discuss the direction of missile research and development.
For any research, setting the general direction is the most important, and the three aerospace industry districts all attach great importance to this.
Zheng Guofeng, Pang Sibo, and other people from the institute greeted him at the door.
Zhao Xingli and his party were welcomed into the institute, and then visited the main research building. They also went to the equipment laboratory room at the back to check out the experimental equipment.
After returning to the conference room, Zhao Xingli sat down and asked, "Professor Zheng, is there any progress in your ballistics research?"
He continued, "You have made a great contribution to Qian Xuesen's ballistic research, and this direction can still be explored. I went to 136 Institute before, and they have made great progress in this direction, saying that it can make more ballistic trajectories appear.
I listened to the entire report and was very thoughtful about the changes!"
He said this to put pressure on Zheng Guofeng.
Institute 136 and Institute 137 also conduct ballistic research, and there is still competition between them. Each institute hopes to outdo the other. Scientific research certainly encourages this kind of healthy competition.
Zheng Guofeng didn't seem to feel any pressure. He smiled and said, "What's so great about that? Our research is much more advanced."
"oh?"
Zhao Xingli became interested, and so did others around him.
Zheng Guofeng shouted to the back, "Ding Hui, come here and introduce to Academician Zhao our latest research."
"coming."
Ding Hui shouted, hurriedly walked to the front, and introduced, "Academician Zhao, we are currently developing a new missile orbit change method."
"If this research can be completed, we can upgrade ordinary missiles so that they can have absolute penetrating strike capabilities."
"This penetrating strike capability allows the missile to change its trajectory in time during any period of flight, and then automatically adjust to a trajectory that can hit the target."
"In addition, the number of orbit changes is theoretically unlimited and will only be affected by power technology."
"When this technology matures, our ordinary missiles will be able to penetrate all existing anti-missile systems!"
Ding Hui said in high spirits.
137 Others present could not help but raise their heads proudly.
Zhao Xingli was stunned when he heard this.
The others who came with him were also stunned.
Zhao Xingli looked at Ding Hui for a long time, then at Zheng Guofeng, and it took him a long time to say, "Are you kidding me?"
"We are doing this research." Zheng Guofeng said seriously.
Zhao Xingli asked with confusion, "If I heard correctly, you are talking about a missile that can change its trajectory at any time. If an enemy missile attacks, the missile will automatically change its trajectory?"
"Then it can automatically adjust and then change back?"
"Are you sure you are talking about ballistic missiles? If cruise missiles are controlled artificially, can I still believe it..."
"Hahaha~~~"
Zheng Guofeng actually laughed when he heard Zhao Xingli's words, "Academician Zhao, let alone you don't believe it, I didn't believe it at first, but we already have a complete theory."
"Ding Hui, tell me more!"
Ding Hui immediately started talking energetically again.
After repeated explanations, Zhao Xingli still didn't quite understand, but one thing was certain, Zheng Guofeng and Ding Hui were not joking.
This can also be seen from the expressions of the other 137 people.
They are indeed engaged in this research and believe that they already have a theoretical basis.
This made Zhao Xingli very surprised. He asked Zheng Guofeng in a low voice, "I still don't understand it. Can you tell me where the basis of this technology comes from? It can't be the Ding Hui in front of me, right? I feel like he doesn't have this
level."
Zheng Guofeng leaned into Zhao Xingli's ear and whispered two words--
"Wang Hao!"
Zhao Xingli suddenly felt like he suddenly realized that such complex mathematical logic could not be completed by ordinary people, that is, only top mathematicians could complete it.
really!
Wang Hao, this makes sense.
But are you sure it's correct?
Zhao Xingli was still a little skeptical because the technology he heard was so high-end that it felt like it transcended the era.
He had to figure it out.
…
Sokai University, Mason Number Laboratory.
Zhang Zhiqiang, Qi Xiao, Zheng Yaojun, Xu Jie, Qiu Hui'an and other students all gathered in the director's office.
Together they looked at the so-called 'big results' on the table.
Zhang Zhiqiang walked over, gently picked up the 'big results' on the table, and asked Wang Hao full of complaints, "Is this the big research you are talking about? Is this the... airplane you designed?"
He is holding a paper airplane in his hand.
The folding of the paper airplane is quite complicated. It is cut and spliced from five special pieces of hard paper. It looks quite delicate.
However, it is still a paper airplane after all.
"Be careful! Don't break it."
Wang Hao quickly reminded, "I folded for more than half an hour!"
"..."
Everyone in the office was silent.
Several people looked at each other in confusion. They couldn't figure out what Wang Hao was thinking. He studied a lot of complicated mathematics and said he wanted to design an airplane by himself, and then folded a paper airplane?
This paper airplane folds really well, but...
It’s a bit weird no matter how you think about it!
Helen walked over and looked at the paper airplane carefully, and suddenly said to Wang Hao, "Teacher Wang, you must have gone through a lot of calculations to design such an airplane, right?"
"That's right."
Wang Hao gave Helen a look of praise, "It took me three days just to calculate it, which involved many complex dynamics issues."
He took the plane from Zhang Zhiqiang, carefully put it back on the table, and continued, "Look at this plane, the thickness of each part is different, even the fuselage is different, look at the wings
, the thickness, direction, and position of each part of the tail wing are calculated in detail, and even the amount of glue in the middle layer is carefully weighed."
"I also designed two thin wings under the wings to make the aircraft more stable."
"This is a very aerodynamic aircraft, and it is also a design strategy calculated by me. Its structure, to a certain extent, can even be said to be perfect."
Everyone else nodded and listened, but most people disagreed in their hearts.
A paper airplane, perfect?
At this time, Wang Hao said the last sentence, "It may be the farthest paper airplane that can be thrown in the world."
