Xinghai Research Institute.

In a quiet office in the southwest corner of the Institute of Astronautics, Academician Chang Huaxiang, who holds the post of technical director of aerospace engineering, is arranging to deal with the aerospace work at hand.

At this moment, there was two knocks on the office door, and a young figure pushed the door open and walked in.

"Yo, rare guest, why are you here?"

Academician Chang Huaxiang, who heard the movement, looked up, was stunned for a moment, and then put a smile on his face.

After smiling and asking, he put down his pen and stood up and walked towards the cabinet, took out a box of tea leaves from it, and prepared to make tea.

For the Aerospace Research Institute, Xu Chuan is really a 'rare guest', aside from the previous stage of Xinghai's manned spaceflight and moon landing, he is rarely seen at other times.

On the one hand, the Xinghai Research Institute itself has four major research institutes, and the person in charge of each can basically handle the work within the institute well, unless it involves the entire research institute or major matters will be reported.

On the other hand, Xu Chuan's own research center is not in the field of aerospace, and mathematics and physics are his main research directions.

Xu Chuan smiled, sat on the sofa and watched Academician Chang Huaxiang make tea, and said, "I want to discuss something with Academician Chang." ”

Hearing this, Chang Huaxiang looked back with some surprise and asked curiously, "Oh, what's wrong?" ”

Xu Chuan said with a smile: "How is the situation of our second-generation space shuttle research?" ”

Chang Huaxiang replied without thinking: "The progress is very good, at present, the design drawings of the second-generation space shuttle have been completed as a whole, and there are still some details being adjusted." ”

"In addition, parts and equipment that can be produced modularly are already being manufactured. A new assembly plant has been established in the Xiashu Space Base, which is being adjusted."

In the office, Chang Huaxiang quickly reported on the research and development of the second-generation space shuttle.

As the technical director of aerospace engineering, his tasks are heavy and heavy.

Whether it is the current space plan, the development of the lunar base, or even the design and manufacture of the second-generation space shuttle, it all falls on his head.

Even with the assistance of Weng Yunzong and Wen Yuanhang, the work task is quite heavy.

But in this case, it is no longer responsible to remember the development of the second-generation space shuttle so clearly.

Xu Chuan nodded, in three or four months, the research and development progress of the second-generation space shuttle has reached this stage, and the speed is already quite fast.

However, for the current situation, it is still far from quenching thirst.

After thinking for a while, Xu Chuan said: "That's the case, Academician Chang, weren't we going to build the second space shuttle before, and then because the optimization work of the second-generation space shuttle was suspended first, I am ready to restart it now." ”

"Restarting the construction of a generation of space shuttles?" Chang Huaxiang asked.

"Hmm."

Xu Chuan nodded and said, "Regarding the situation of 'space travel', Academician Chang should also know a lot. At present, our space capacity is completely insufficient, and we can only meet the needs of scientific research or 'space travel'. ”

"But the current space travel business is a budding industry, if we can gain a firm foothold in this area and expand the business volume, the future aerospace research institute will not be self-financing and scientific research funds, and may even be able to feed back the institute's funds in the future."

At present, all the R&D and engineering funds of the Aerospace Research Institute come from the grant of the Xinghai Research Institute.

The funds of Xinghai Research Institute mainly come from three aspects: national funding + national project funding + self-management.

The first two account for the majority at present, but the nature of the Xinghai Research Institute is very special, it is not a state-owned enterprise, and the final funding must be self-operated after all.

The business of space travel is currently aimed at the top wealthy people, and if they can be monopolized, there is no doubt that it will bring huge income to the space research institute.

Chang Huaxiang thought for a moment, frowned slightly and said: "Yes, it can, but this will inevitably affect the R&D, design and manufacturing of the second-generation space shuttle." ”

"Judging from my estimates, it may delay the appearance of the second-generation aircraft for about half a year."

After a pause, probably worried that Xu Chuan would think this time was too long, he then added: "After all, at present, the only domestic space shuttle that can assemble and manufacture the space shuttle is the production line of the Xiashu Space Base. ”

Xu Chuan said with a smile: "Half a year is not a long time, waiting for half a year can bring us more than a billion meters of gold, and we can wait." ”

"Second generation aircraft"

Sighing, he continued, "If it really doesn't work, then let it go first." ”

There's no way, they all say that having milk is a mother, and the same is true in the scientific research community, and being rich is a father.

Although I feel sorry that the research and development of the second-generation aircraft has been stretched, but...

More than a billion meters of gold, it's more fragrant

After discussing the matter of restarting the assembly of the first-generation aircraft, Xu Chuan continued: "By the way, Academician Chang, there is another matter, which is about the NASA space. ”

“NASA？” Chang Huaxiang was stunned for a moment, and asked curiously, "What's the matter?" ”

Xu Chuan briefly said NASA's request for help, and then asked with a smile: "If I'm not mistaken, there seems to be a prohibition agreement called the "Wolf Clause" in the United States, right?" ”

Chang Huaxiang nodded and said, "Yes, in 2011, the "Wolf Clause" was passed over there, restricting NASA's contact with our aerospace field. Of course, the main thing is to limit cooperation in satellite technology and national defense. ”

Xu Chuan smiled and said, "Then that's interesting." If the United States has passed a law to explicitly stipulate this thing, what does NASA mean this time? ”

Academician Chang Huaxiang thought for a moment, and said in a slightly suspicious tone: "Coming for our Xinghai? Want to study the small fusion reactors and aerospace engines above? ”

On Xinghai, there are a lot of things worth thinking about, but only these two things are worth NASA breaking the Wolf clause.

Xu Chuan thought for a moment and said, "Is it possible to be a little more serious?" ”

Chang Huaxiang was stunned for a moment: "More serious?" ”

Xu Chuan nodded, and spit out two words in his mouth: "Hijacking." ”

"Hijacking?" Academician Chang Huaxiang opened his mouth wide, looked at Xu Chuan in a daze, and said in surprise: "This shouldn't be possible, right?" ”

Xu Chuan shook his head and said, "For the United States, there is nothing wrong with speculating that the bottom limit is lowered. NASA risked breaking the Wolf clause to work with us, and I think he probably wanted more than just a look at the Star Ocean. ”

"If you snatch control of the Xinghai during the space flight and drive it back to the United States, how likely do you think this is, Academician Chang?"

Hearing this, Chang Huaxiang immediately fell into deep thought.

In theory, hijacking is not out of the question.

If no one had thought of this, a riot by NASA engineers or pre-arranged crews during the course of a space cooperation could indeed pose a threat to the astronauts and staff on the space shuttle.

But normally, this possibility is really unlikely, very small.

After all, they are not vegetarians, and 100% of the personnel, equipment, and equipment will be inspected in all aspects before carrying out cooperative tasks.

Under this kind of preparation, they also let the other party hijack the plane, which can only show that they are waste.

After thinking for a while, Chang Huaxiang looked up at Xu Chuan and said, "Theoretically, such a thing as hijacking is indeed possible, but the probability is not too great. In particular, we now have a guess in advance, and after we have made preparations, the probability of it happening is almost non-existent, and it is basically impossible. ”

After a slight pause, he continued: "If you are worried about this kind of thing, I think it is better for us to refuse NASA's cooperation." ”

After thinking for a while, Academician Chang Huaxiang still gave a sound suggestion.

Xu Chuan smiled and said, "No, no, I think this cooperation is necessary to follow." ”

"It's a good thing for us that NASA broke the Wolf Clause this time. So this cooperation is important for me and for the country. ”

"As for hijacking, if NASA came with that in mind, we would be prepared. When negotiating conditions, try to reduce the number of boarding personnel on the other side as much as possible. ”

Hijacking is such a thing, even if NASA and the United States want to do it, it is in vain if there are not enough manpower.

This kind of thing, it is enough to control it well.

But on the contrary, it was important for them to break the Wolf clause.

This is not to say that the Wolf Clause is important, in fact, the Wolf Clause is not important to them, and it cannot limit China's technological development in the field of aerospace.

For example, the Long March series, Chang'e lunar exploration, Zhurong fire exploration, and Xinghai's manned lunar landing were all developed under the Wolf clause.

What is important is not the Wolf Clause, but the influence and power of the authorities in the international arena.

The development of technology is only one aspect of the matter for aerospace, but if they want to occupy a leading position in the aerospace field, then dismantling the influence and power of their opponents in the world is one of the most important and critical things.

And there is no better way to do that than to dismantle someone from within.

The interstellar era must belong to Huaguo!

After handling the work in the aerospace field, Xu Chuan transferred the work from the Xinghai Research Institute back to NTU, and put it on the matter of reconstructing the core theory for the chemical calculation material model.

I have to say that the efficiency of the two students, Ding Rui and Gu Bing, is still quite high.

Even after a large math report meeting in the middle, which was delayed for a lot of time, he still properly completed the preliminary preparations for Xu Chuan's arrangement within a week.

With the help of the two of them, Xu Chuan's task of collecting and sorting out literature reviews and other tasks became much easier.

In the office, the three of them sat together, sorting out the materials, papers, and some experimental data collected during this time.

"Professor, can you tell me about the model theory of the Gouy-Chapman-Stern electrochemical structure interface, and the electrode reaction model for coupled homogeneous chemical reactions?"

Sitting next to Xu Chuan, after picking out a paper from the materials that had been preliminarily sorted, he turned his head to Xu Chuan and asked.

Since graduating, he hasn't worked in an office with Xu Chuan for four or five years.

The current scene made him can't help but substitute into the original study time, which was very hard and tiring at that time, but very satisfying.

His talent is not as good as Amelia's junior sister, and he is not as good as his mentor Xu Chuan, many times he needs longer to understand the knowledge points he has talked about, and he can only spend longer time sitting in the office to study than others, and he also needs to ask more questions to gain the same amount of knowledge.

However, his thirst for knowledge never stopped.

Xu Chuan turned his head to look at it and explained casually: "The core of the electrode reaction coupled to a homogeneous chemical reaction is the generation and transfer of free radical ions. ”

"Whether it is an EE reaction or an EC reaction, including ECEC and EC2 that are extended later, they are all based on ion rearrangement."

"You just need to understand that the addition of electrons in the antibond orbital or the acquisition of electrons in the bonding orbital will reduce the bond energy, and the chemical bonds are prone to breaking and rearranging, so that a chemical process can occur, and the core mathematical formula can be established based on this."

"In addition, the characteristic time of the electron transfer process can often be controlled by the sweep velocity, which you can calculate as a core variable."

Xu Chuan briefly explained the processing of the electrode reaction model coupled with homogeneous chemical reactions, and Gu Bing hurriedly put down the paper in his hand first, took out a small post-it note from his pocket, and recorded the relevant knowledge points.

On the side, Ding Rui, who was sitting next to the two of them, flipping through the literature and looking at the materials, suddenly asked: "Professor, if I remember correctly, the model you built for the Materials Research Institute is quite perfect, right?" How can you think of refactoring all of a sudden? ”

Xu Chuan smiled and said, "Because it's not suitable." ”

"Not suitable?" Ding Rui looked at it in surprise, a little puzzled.

He studied functional analysis, so naturally he was also exposed to such things as mathematical models.

He knows the computational model of chemical materials at the Chuanhai Materials Research Institute. After all, the vigorous 'monoclinic gamma sulfur' that made a lot of noise some time ago has something to do with it.

The mathematical model that can calculate the stability of the 'monoclinic gamma sulfide' is already at the ceiling level in his opinion, but Xu Chuan still says that it is not suitable.

Xu Chuan nodded with a smile and said, "Yes." In fact, in a way, the model I designed before was quite good, because it can be used to simulate the computational reaction process mathematically, which is something that most materials models on the market can't do. ”

"However, with the passage of time, the experimental data and computing power required based on the underlying logic are getting bigger and bigger, and the current computer system can no longer support it, so it is no longer suitable."

After a pause, he looked at Ding Rui and said with a smile: "Sometimes, the difficulty is not the peak, but when you stand at the peak, give up the existing achievements and start over." ”

"But if you want to go further, then learning to give up at the right time and find a new path is the real choice."

"Learn to give up at the right time and choose a new path"

This sentence echoed repeatedly in his mind, and looking at the paper in his hand, Ding Rui nodded thoughtfully.

It may be difficult for him to understand now, but in the future, this sentence will affect his life.
