Chapter 1389 Rapid Advancement (4K)

Considering the current strange and "historical spiral" development environment of Blue Star, Gu Qing can no longer sit behind the scenes like before and rely on the Jiuzhou Think Tank and Zhang Tianhao and other confidants to promote technological leaps.

So, when he saw Yang Shixiong, the person in charge of the space station R&D project, and other doctors and engineers frowning but unable to come up with a substantial plan for progress, Gu Qing sighed.

He walked to the sub-operating station next to the main operating station, turned on the simulation system and the intelligent AI Tiangong "plug-in", and while sorting out the data, he said: "For the design of the space station, we need bold design, careful verification, and solid and radical.

There is no air pressure in outer space, but the air pressure inside the International Space Station is as high as 101 kPa. We all know that engineers designed this to simulate the natural atmospheric pressure on the ground of the blue planet, but this also means that some sections of the International Space Station have been under extremely high internal and external pressure for a long time.

The data from Tiangong's investigation shows that the thinnest part of the wall of the experimental cabin on the International Space Station is only 4 mm, but it has to withstand a high pressure of 101 kPa, which naturally leads to many problems.

For example, four years ago, the air leakage problem occurred in the International Space Station. After After investigation, the astronauts of the International Space Station locked the leak point on the Zvezda service module, and when they found the leak point, the temperature inside the Zvezda service module also increased.

Three years ago, Russian astronauts found six cracks inside their country's Dawn module, which means that the Dawn module has shown signs of metal fatigue.

Two years ago, a year ago, and even half a year ago, problems were found in the International Space Station one after another. The countries and institutions cooperating with the space station gloated over the problems in the modules that others were responsible for, while looking at the problems in the modules they were responsible for with a sad face.

In fact, once these design and construction weaknesses are used for more than the design service life, these problems are inevitable.

However, the frequent occurrence of these problems does not mean that the design of the International Space Station is The design has no advantages that can be absorbed.

As the international space station developed by the technological powers of Blue Star at that time in conjunction with countless scientists and engineers, its overall design adopts a truss-mounted cabin structure. The service cabin, experimental cabin and other facilities are developed at both ends of the truss, and when they are partially vertically crossed, they form a "keel frame", which naturally strengthens the rigidity of the space station.

Our ring-shaped space station can also use high-strength keels in the core part of the main body, and then these ring-shaped space station cabins do not need to use pure water as breeding. We can completely use the ring cabin to create centrifugal force to generate artificial gravity inside the space station. Of course, I know that this is a very controversial design.

For example, it is necessary to reach an extremely high rotation speed to produce gravity equivalent to the natural environment on the surface of Blue Star. The high rotation speed will give the mechanical structure of the space station The structure and overall heat dissipation will bring great difficulties, and it will also bring great challenges and psychological pressure to astronauts and other crew members in the space station.

But this problem can be completely solved, because we don’t need to pursue the same gravity as the ground of the blue planet, we only need a stable gravity field, so the rotation speed can be controlled within the acceptable level for us humans.

And as long as you pass the training of the Future Warrior Project, you can basically be stress-free or easily withstand this gravity change and centrifugal rotation.

As for the high-speed rotation, it is difficult for air molecules to achieve a uniform and stable distribution throughout the space station, and it is easy to make the core area of ​​the space station the center of the tornado. This problem can be solved by setting up different living and working areas and letting astronauts entering the core area wear aviation suits.

Of course, in scientific experiments, if the ring-shaped space station relies on rotation to create gravity, then the central axis area will be difficult to achieve a microgravity environment due to the small rotation effect, which is not conducive to scientific experiments. Don’t forget what our stage focus is?

It’s the lunar base!

We don’t need to conduct experiments in the space station for decades, and we don’t need to pursue the so-called zero gravity and microgravity on this ring-shaped space station.

If we can build a space station, we can design, develop and build the second, third, and even the fourth and fifth space stations in the future.

Everything is difficult at the beginning, but as long as we start, we can continue to charge forward! "

Reduce the amount of tasks, lower the requirements, and increase confidence and resources. The speeches around the three strategies directly made the atmosphere inside the laboratory warm again.

The smarter people are, the easier it is to fall into their own ideological misunderstandings and cannot extricate themselves.

Since entering Jiuzhou Technology, they have seen a lot of industry giants and cutting-edge industry knowledge. These scientists and engineers who are considered elites in the outside world have naturally raised their sights a lot, and their requirements for themselves are also equal to those of others.

This leads to them thinking about perfection after receiving the task. As long as there is any unqualified link, it will be like a thorn in their throat, making them unable to let go.

Gu Qing's initial request was to build a space station as a springboard for Jiuzhou Technology to the lunar base, develop some equipment needed for life in outer space, and collect data and information on outer space creatures. For example, if humans live in outer space for a long time, will there be some changes in genes, bones, and internal organs?

While these scientists and engineers are working on research and development problems day and night, they unconsciously regard this "mid-stage task" as their top priority.

It was Gu Qing who tore the window paper this time that made them suddenly look back and realize that they seemed to have been running down another dead end.

But ease is only easy for some people.

Yang Shixiong, the head of the space station R&D project, still frowned after hearing what Gu Qing said.

He lowered his head and murmured to himself: "Even so, the research and development and manufacturing technology of the circular space station are still very difficult.

To simulate the Blue Star environment without pursuing Blue Star gravity data, the radius of the ring space station must exceed 100 meters. At the same time, the orbiting cabin and the keel cabin are big troubles. It is better for us to just build a ring space station.

After all, it is springboard technology, with a single ring, and the main keel structure will be developed later.

But even so, it is still difficult to solve the problems of a huge and sophisticated rotating space station in the short term, whether in terms of design structure, space station engine power or system control. "

When Gu Qing heard his doubts, he did not shake his head, but directly gave a more practical solution: "Since we want to simplify it, we can use a combination of microgravity environment and short-term rotation to provide astronauts with practical solutions when they need it. gravity environment.

When materials and energy are about to be damaged and limited, power output is slowly paused. "

The plan given by Gu Qing was like a meteor that cut through Yang Shihun's dark sky shrouded in countless questions.

The middle-aged man's eyes instantly flashed with excitement, "Yeah! Yes! An ordinary ring! It's an ordinary ring! From the very beginning, we can build the keel, and then build the ring on top of the keel.

It was very simple at the beginning, and gradually increased in difficulty. Step by step, we collected enough detailed data, added structure step by step, and improved the design.

In the future, a small ecological ring can even be expanded on this basis.

Not just a few astronauts, as long as the materials permit and our plan is correct, this space station can fully guarantee the lives and work of dozens of astronauts in the future.

In this way, in addition to space experiments, we can also develop space tourism, and even arrange for astronauts and scientists who are going to the lunar base to be on the space station as their first stop. After adapting to life on the space station for a period of time, they can return to Blue Star for repairs. , wait until everything is safe, and then set off to the moon.

This space station is a training base for novices! Experimental base!

As long as the direction is correct, we can collect more data. This data can fully support our design of the second space station. We can even rely on the huge area of ​​​​the first space station to achieve profitability! "

The more he thought about it, the more dazzling the light in Yang Shixiong's eyes became.

The other people in the laboratory have also entered a state of excitement at this time.

"The boron nitride ceramic matrix composite electric propulsion system, as the propulsion technology of the Hall thruster, combined with the wireless array engine, can achieve no need for fuel under normal conditions and only use the ion flow ejected from electrical energy to provide power for the core module. Under special circumstances, A composite propulsion system that uses fuel and electrical energy to provide thrust.”

“The high-performance silicon carbide particle-reinforced aluminum matrix composite material jointly developed by the Titanium Star Department and the Aerospace Group can be used in key components of the space station’s solar wing extension mechanism.

And we don’t need to use lithium-ion batteries. We can use graphene batteries to ensure that more energy can be stored. "

"Medical sample analysis instruments, gravity analysis instruments, electromagnetic analysis instruments, and radiation analysis instruments can all use magnesium components and special titanium alloys from the Titanstar Department, which fully meet multi-functional requirements such as weight reduction, corrosion resistance, and interference resistance."

"But what to do with the engine? What to do with those high-temperature components? Although space is not a mountain of fire, there is a huge temperature difference between the sun and the shade. The engines on our space station do not have an environment suitable for air cooling and natural water circulation for cooling. "

An engineer with white hair on the sideburns and the sad faces of the team around him formed a very sharp contrast with the radical and excited scientists and engineers around him.

When Gu Qing looked around, he naturally noticed something strange about this small team.

He glanced at the information provided by Xuanwu in his SR1 glasses and sighed in his heart.

"When I let you enter the special equipment research and development center, you were unwilling to separate, so now you can't get some technical authorization, just drink and peck."

However, Gu Qing would not express the sigh in his heart on his face.

He walked straight to the side of the small team and said in a caring tone: "Dr. Xu, I heard you are thinking about the problem of high-temperature components?"

Xu Changqing heard a familiar clear voice coming from beside him, and he subconsciously turned his head and looked over.

"Well, Gu, Mr. Gu."

Facing this middle-aged man who was a little embarrassed to say hello, Gu Qing waved his hand and said: "Don't feel embarrassed, science and technology research and development is not going to be doomed if you sleep in the wrong place. In the dispute between you and that colleague, we were all dealing with the issue and the person.

So you do have a problem?

It's better to say it out loud. If one of us thinks about the shortcomings and the three of us think about the strengths, we might be able to find a breakthrough direction. "

Faced with Gu Qing's attitude, Xu Changqing nodded slightly.

Of course he knew that his boss was not lying. If Boss Gu, who had the vast technology and R&D resources of Jiuzhou Technology, could not solve the problem, then the only place on this planet that could solve this problem was in a few extremely secret and highly confidential laboratories.

So he got straight to the point and directly stated the problem that trapped his team.

"For power engines other than the wireless array engine used in the space station, the thermal barrier coating material for their high-temperature components cannot be solved for the time being.

According to international solutions, this thermal barrier coating generally uses a ceramic coating. As a thermal protection coating for high-temperature components of aircraft engines and gas turbines, it can play a good heat insulation role for related important mechanical components and special material components, directly improve the service conditions of high-temperature components, extend the service life, and even save the most precious fuel of the space station.

Currently, the most commonly used thermal barrier coating material in the world is zirconium oxide-based material. This material is expensive and difficult to manufacture. Moreover, it will undergo phase change at a high temperature of about 1200 degrees Celsius. The coating will soon fail if it falls off, which will directly lead to an exponential decrease in service life.

In the design of our space station, the operating temperature of some special engines can reach an ultra-high temperature of 2000 degrees Celsius. This temperature will directly cause the thermal barrier coating material to fall off, and even after a few operations, it will be scrapped and invalid."

"This problem? It is indeed an international problem. I have learned about it before."

Gu Qing's words made the atmosphere of the research and development team a little more depressed.

A problem that even the boss of the company cannot solve must be a world-class problem that may not be solved in a few years.

Even if they are experts in this industry, they will feel disappointed after knowing Gu Qing's judgment...

"But you didn't have the authority before, so you didn't know that our company's special equipment research and development center has developed ultra-high temperature resistant materials, and they are customized materials for engines, engine systems, and aerospace products.

In addition, the special metal engineering laboratory that our company cooperated with Yunming University of Technology just had new results a while ago. The ultra-high temperature tantalate thermal barrier coating technology they studied can increase the maximum operating temperature to 1700 degrees Celsius to 2100 degrees Celsius, and there is even room for improvement in the future.

With the high temperature resistant metal materials of the special equipment research and development center, it should be able to solve the problem of your project."
