Chapter 472: A daughter inherits her fathers legacy
"...?!"
Looking at the letter of intent in front of him, the expression on Xu Yun's face was slightly surprised.
If he had some expectations for coming to the Xichang launch base today, then this document was really beyond his expectations.
After a while.
Xu Yun couldn't help but raise his head, looked at Li Hua and Ge Tongyou, and asked, "Gong Li, Professor Ge, this is..."
After hearing this, Li Hua pressed his chin towards the document and said with a smile:
"Dr. Xu, as you can see, this is a letter of intent for the combination of gravity gradiometers from Jilin University."
"This letter of intent designs an efficient model of a gravity gradiometer, but it is limited to the structure of the instrument, and non-structural aspects... such as the surveying and mapping module have not been solved."
"Actually, as one of the leading aerospace bases in China, we receive many similar letters of intent or cooperation letters every year, and this one..."
"It comes from early January this year." As Li Hua said.
With the development of various needs, today's Xichang Satellite Launch Base is no longer an organization with purely official functions - note that the functions mentioned here are the projects executed, and it is still 100% official in terms of relationships.
Nowadays, the territory of the base has expanded to various fields, such as providing satellite transportation services to Southeast Asia or domestic enterprises, and the tourism mentioned before, etc.
Other than that.
The Xichang base also has a deeper area, which is to cooperate with major institutions and universities to conduct instrument research and development or technology output.
One of the most representative ones is the stratospheric aircraft. Currently, many universities in China have relevant research groups working on this thing.
At present, most of the technology in the industry, whether it is aircraft lift-off or hovering, comes from the Xichang launch base - because the prices in Xichang are always cheaper.
All the students who have walked 500,000 in this life should know this.
Chengdu Aircraft's related technology licenses are basically five-year and multi-million level, and there are many small aircraft that are not yet in use, so it is quite a waste to buy them.
Prices in Xichang are generally around tens of thousands. If funds are really limited, you can even buy a small knife...
Of course.
If the research team has insufficient funds, you can also send a letter of intent to try to persuade the base to jointly develop with you.
Xichang Satellite Launch Base receives a large number of letters of intent every year, and the base will first conduct a preliminary screening of these letters of intent.
Those with significant value will be given priority, and the rest will be piled into the reserve area for discussion at the first meeting at the end of each quarter.
According to Li Hua.
The letter of intent in Xu Yun's hand was issued in early January, which means that it has not passed the previous preliminary examination.
screen.
Normally, it would discuss the resolution in detail at the end of March or early April. It is hard to say whether it will be adopted or rejected.
So this is not a coincidence at all, and it was not sent this morning or two days ago. It is actually normal to see drawings or plans related to the gravity gradiometer here in Xichang.
What really surprised Xu Yun was...
"Gong Li, are there any university research groups in China currently doing gravity gradiometers?" Hearing Xu Yun's words.
Academician Pan beside him couldn't help but nodded.
Needless to say, the importance of the gravity gradiometer is, in a sense, a national priority that is more precious than the photolithography machine.
device.
But since it is an important weapon of the country, it also means that its technical barriers are very strong, and it is not a project that can produce results immediately.
Therefore, in terms of research value, it is contrary to the projects of most universities.
Therefore, there are many official institutions in China that engage in gravity gradiometers, such as the 3xx Institute of the Third Academy of Sciences, etc., but university research groups are relatively rare.
Looking at Xu Yun who was a little confused, Li Hua thought for a moment and asked:
"Dr. Xu, since your research group involves the mapping module of gravity gradiometer, you should know the authority of domestic experts on gravity gradiometer, right?"
Xu Yun nodded: "I've heard a little bit about it."
Upon seeing this, Li Hua stretched out his finger and pointed at the words Jilin University, which is the cooperative unit: "Look at this, how do you think of it? Did you think of anything?"
Jilin University?
Xu Yun was stunned for a moment, but soon he realized something. He suddenly raised his head and looked at Li Hua: "Li Gong, are you talking about...Professor Huang Danian from Jilin University?"
Li Hua nodded with emotion, and then sighed:
"That's right, this research group was started by the students who were formerly led by Huang. Huang Yuting on the application form is Lao Huang's biological daughter."
Xu Yunmoran. Professor Huang Danian.
This was the country's top expert on gravity gradiometers, a pillar of the country who had made astonishing achievements. (He was introduced in Chapter 347, so I won't go into details here)
The gravity gradiometer of the Shandong ship that was officially delivered in 2019 was made by Professor Huang Danian. Unfortunately, on January 8, 2017.
Professor Huang Danian died due to ineffective treatment. The following year, he was named one of the ten national backbones who died in 2017.
When he first heard the news, Xu Yun had lamented the death of Professor Huang Danian for a long time. The University of Science and Technology also sent people to attend the memorial service to pay tribute.
However, because there is not much connection between the school and the major, Xu Yun does not know the changes in related research after Professor Huang Danian's death.
When he wants to come.
Although the gravity gradiometer is a very important research, its nature is not suitable for use as a university research group. What is valued above all is Professor Huang Danian’s personal ability.
Therefore, after Professor Huang's death, this research group probably disbanded, and everyone in the group went their separate ways.
The result was unexpected...
Professor Huang Danian’s daughter Huang Yuting actually inherited her father’s legacy and continued to carry out her father’s research? You know.
This kind of research cannot be sustained by relying on emotions.
After the death of Professor Huang Danian, there will be big problems or disagreements whether it is funding, policies or within the research team members themselves.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! I thought of this.
Academician Pan next to Xu Yun seemed to have recalled something, and lightly patted his forehead:
"Huang Yuting... Oh, I remembered, she is Professor Huang's daughter who works in ultra-high-precision machinery. I have some impressions of her."
"When Professor Huang passed away, she seemed to have already graduated with a Ph.D., and was rated as one of the 100 people of the Academy of Sciences. She should be thirty-five or six now, right?"
Li Hua picked up the teacup and poured a glass of water for Academician Pan and said:
"Well, I'm thirty-six. I used to work in the Third Hospital, in the same direction as Lao Huang."
"After Lao Huang's death, she transferred her working relationship back to Jilin University. She was promoted to a senior position the year before last and is now the deputy director of the Department of Emerging Interdisciplinary Studies at Jilin University."
"But everyone in the scientific research industry knows that feelings are one thing, and results are another - and many times, the latter is the reality."
"Jida provided funding to Huang Yuting for two years, but the research team never produced results, so it gradually reduced its support starting in 2020, and many members of the research team also left the project team."
Everyone was silent after hearing this.
Although both the country and Jilin University gave Professor Huang Danian a high evaluation during his lifetime, unfortunately, this evaluation could not be fully reflected in reality.
Just like the young master's succession in history, unless you are a time traveler, it is impossible to quickly settle the interests and demands of all parties.
The same goes for scientific research.
After the death of Professor Huang Danian, unless Huang Yuting quickly reveals her talents and achieves breakthroughs, she will inevitably avoid a reduction in funding and a loss of talent.
Then Li Hua paused and continued:
"However, Huang Yuting has never given up on this topic. Although her professional title is high, her category is not professor, but
Researcher - so she can have a lot of time to devote to the research of gravity gradiometer."
"The letter of intent received by our base is the latest achievement of Huang Yuting's research team."
"Of course, as far as I know, she not only sent this letter of intent to our base, but also to Jiuquan and Longcheng. It can be regarded as a wide-ranging Internet cafe."
Xu Yun took the letter of intent in front of him and looked at it for a few more times. After thinking for a moment, he asked Li Hua: "Gong Li, did you know that the base has conducted a demonstration on this letter of intent?"
Li Hua nodded and answered straightforwardly:
"Of course, we respect Professor Huang Danian's deeds very much, so we reviewed the letter of intent as soon as we received it - even faster than the conventional preliminary screening."
"But unfortunately, this letter of intent is mainly aimed at the structural design of the gravity gradiometer, and there are no ideas for the other surveying and mapping modules and balance modules."
"Objectively speaking, this situation is normal. After all, if it is a complete design plan, there is no need to call for a letter of intent for collaboration."
"It's just that for our base, there are still too many aspects of this project that need to be polished, so we can only temporarily put it in the preparation area to prepare for discussion at the next ** meeting."
Only then did Xu Yun realize that this was what happened...
But soon, his heartbeat rate increased slightly.
Li Hua's words seemed to explain the difficulties in implementing the letter of intent, but in fact they also revealed another piece of information:
There is no problem with the structure designed by Huang Yuting - at least it can withstand preliminary verification.
Otherwise, Li Hua could just say that the plan is not feasible, and there is no need to mention the subsequent steps of surveying, mapping and balancing.
In the development of gravity gradiometers, the structural design of the instrument is actually a very important step because of the existence of embargo barriers.
Due to embargo barriers, Rabbit cannot directly copy the latest work and can only try it step by step.
The current gravity gradiometer is constantly being optimized, so the structure remains almost the same every once in a while.
For example, the gravity gradient meter on the Shandong ship uses a grouping structure of 37 and a relay thread of 126 to achieve appropriate actual combat parameters. (This is information that can be disclosed)
The gravity gradiometer of the Fujian ship is larger.
The grouping structure is 5x9, the relay threads are up to 324, and there are also various hardware to prevent Guangdong people from chewing, etc...
Then Xu Yun thought for a while and asked Li Hua:
"Gong Li, if the surveying module and the balancing module can solve the problem, plus Researcher Huang's structural drawing..."
"Do you think there's any chance of a temporary version of the gravity gradiometer?"
Li Hua raised his eyelids and glanced at him, and hesitantly clicked his tongue. He did not give a direct answer, but confirmed:
"Dr. Xu, your default usage scenario is Yongling, right? - To be honest, I don't know much about Yongling. Are there many mountains around it?"
Xu Yun nodded and affirmed:
"Yongling Mausoleum is backed by Yang Cuiling of Tianshou Mountain, and there are many mountains and trees around it. After all, it is the tomb of an ancient emperor, so the landscape must be suitable."
"What's the height of the mountain?"
"The height is not very high. Although the main peak of Tianshou Mountain is one thousand meters high, the height of Yangcuiling is only over three hundred meters - and there are only two peaks of this height."
"Is Yongling inside the valley or outside the valley?"
"Outside the valley, near the southern foot." "What's the depth of detection?"
"Twenty...no, thirty meters underground." "Is there any standing water?"
"have."
Li Hua conceived the picture in his mind, then used some parameters in Huang Yuting's letter of intent to make a rough calculation, and finally said to Xu Yun:
"Dr. Xu, based on preliminary calculation results, the balancing module probably requires three modules: a connecting plate, a dynamic balancing sleeve, and a rotor dynamic balancing adapter."
"In terms of parameters, it's about 3392
g—,1696g—,—27.5in, the aerodynamic reference point is about 0.02."
"Of course, these are just simplified calculations, but the approximate range should still be guaranteed." After saying that, he turned his attention to Ge Tongyou beside him.
Ge Tongyou took the calculation paper with understanding and read it carefully again. Less than half a minute later.
This chapter is not over yet, please click on the next page to continue reading! He took a deep breath and said to Li Hua:
"Gong Li, with our current capabilities... it shouldn't be a big problem to create this set of balance modules." Hearing this.
Xu Yun's eyes suddenly lit up.
Once the mapping module, gradiometer structure, and balance module are all in place, a simple gravity gradiometer seems...
Is it really not that difficult? Come to think of it.
Xu Yun couldn't help but rub his hands and asked Ge Tongyou eagerly:
"Professor Ge, does that mean we have a high chance of completing this project?" Unexpectedly, Ge Tongyou was silent for a moment and shook his head slightly:
"Dr. Xu, you should know that in scientific research projects, feasibility is one thing, and process implementation is another."
"For example, if you look at this letter of intent, the preset funding is 300,000 Chinese coins and some equipment. Taking into account losses such as casting molds, it is estimated to be around 500,000."
"Projects of this level are theoretically subject to resolution by the ** committee..." Xu Yun couldn't help but exclaimed:
"No..."
Then he looked at Mr. Wang bitterly and cast a look for help.
Mr. Wang was in good spirits today and had the energy to pay attention to the conversations between several people. When he saw Xu Yun asking for help, he glared at Ge Tongyou angrily:
"Okay, Xiaoge, it's not easy for Xiaoxu to come all the way from Chengdu. Besides, you have many children and grandchildren. Xiaoxu hasn't even found a girlfriend so far, so don't tease him."
Xu Yun: "????"
Although Mr. Wang’s words seemed to be relieving him, why did they sound weird? [Besides] What the hell are these two words?
the other side.
Ge Tongyou's inner emotions were obviously not as complicated as Xu Yun's. After being pointed out by Mr. Wang, he laughed:
"Just a joke, just a joke."
"Dr. Xu, if nothing else, just based on the face you and Academician Pan have earned for our country this time, I have no excuse for this matter."
"So Dr. Xu, don't worry, I will organize manpower this afternoon, and within two days, the balance module issue will be finished!"
Note:
I will be discharged from the hospital tomorrow and will take a day off. I hope all readers will approve it.
