Technology: breaking the hegemony that monopolizes the world

Yang Shixiong, the person in charge of the space station research and development project and one of the top engineers of Jiuzhou Technology, is "high-spirited" in the laboratory at this time.

Previously, because of the high cost of living on the space station, he developed a regenerative life support system tailored for astronauts while ensuring safety and health.

However, due to some problems and mistakes, some ideas were corrected by Gu Qing. But when it came to the space station project, which he was best at, it was already in a different state.

"The three-cabin T-shaped configuration, that is, the Wentian experimental cabin and the Mengtian experimental cabin form the horizontal line of the T, and the Tianhe core cabin forms the vertical line of the T. At the same time, there are multiple manned and cargo spacecrafts that transport them back and forth. goods.

This will ensure that our Daxia Space Station can easily provide six astronauts with long-term supplies and energy in orbit during normal operation. They are similar to ordinary express logistics, and the space station is the house where we live. "

Looking at the sketches drawn by the other party, and Tiangong explaining and optimizing the project beside him, Gu Qing only felt relaxed.

Blue Star has talents, and it does not require him to do his best for everything. Elites like this one who were hired from Daxia Aerospace Group can answer many questions.

“If we want to build an excellent space station, the most important thing we should do at this stage is to lay a good foundation, and we must also design the best core module as the foundation.

The thrust of the JZ-404 launch vehicle is very good and can fully support us in designing a larger core module and safely launching it into orbit.

Then the JZ-405 launch vehicle can carry the supply cargo compartment and dock with the docking port of the core module, and then fly together in orbit. This process is an axial rendezvous and docking, just like two track and field athletes on a runway. Passing the baton.

In my opinion, it is easy to connect, but difficult to leave.

After the cargo bay is docked and another test module is docked, after the three cabins are combined, astronauts complete the space mission and when leaving the space station, they need to separate the second core cabin, then go around behind the first core cabin, and then go under the first core cabin , perform radial rendezvous and docking verification.

This step is more difficult than axial rendezvous and docking, but our robotic arm is very sensitive and can help transfer the second core module to the docking port.

…

The Kyushu Space Station is an estimated 100-ton assembly, including two core modules and two cargo compartments.

Whether it's leaving the space station and returning to Blue Star. Or the JZ series rocket on the ground can fly autonomously to the front of the core module for docking, which requires a mechanical arm to assist in the transition.

In the early stage, we can use intelligent robots to work in the space station to avoid personnel accidents.

From the docking of the core cabin to the cargo cabin, the materials are transported back and forth once.

At this point, the task of verifying key technologies for the construction of the Jiuzhou Science and Technology Space Station has been completed. "

After Yang Shixiong, the leader of the space station research and development project, finished explaining this process, there was a warm applause in the laboratory.

Unlike the research and development, manufacturing, and launch of the International Space Station and Daxia Space Station, Jiuzhou Technology’s internal view of the space station project is “difficult but not very difficult.”

Because there are a series of problems that need to be overcome from the space station’s building materials, polymer materials, special insulation materials, radiation protection materials, robotic arms, docking technology, space station systems, space station electronic equipment, chips, launch vehicles, etc., Jiuzhou Technology has internal corresponding answers can be found.

Another reason why Yang Shixiong can serve as the person in charge of the space station research and development project is that he has a bunch of "immediate bosses" above him.

The director of Jiuzhou Technology's Titan Star Department, the director of the semiconductor department, the Jiuzhou Technology Think Tank whose members no one knows the true identity of, and the president of Jiuzhou Technology Gu Qing, all four forces have jurisdiction over it.

In a sense, Gu Qing can even easily intervene in the progress of the project without any intervention, just through other people.

When the crowd's applause subsided a little, Gu Qing walked into the laboratory.

When the project leader Yang Shixiong and other experimenters saw Gu Qing's figure, they immediately stopped what they were doing and began to welcome the big boss.

Gu Qing ignored the compliments and blessings in these welcomes. After chatting with Yang Shixiong for a few words, he walked straight to the operation console, stared at the data on the display screen and the dynamic graphics of the space station simulation, and asked: "What's the matter?" A 100-ton space station. As far as I know, the Daxia Space Station is 50 tons.

When the second core module of our Kyushu space station was launched, it was so big that for safety, it used axial rendezvous and docking to connect with the front end of the spherical node module of the first core module. This design is very good.

But have you ever thought about the final docking of the four cabins? What to do with the reaction force generated when they dock again and again?

Does the attitude adjustment engine work need to be adjusted every time?

In the short-term mission time, based on the working life of the attitude adjustment engine and wireless array thruster we designed, maybe there will be no problems within twenty years, but what about twenty years later?

It should be noted that after completion, the Jiuzhou Space Station also contains four complete functional compartments: core cabin, cargo cabin, experimental module, and manned spacecraft. It is a complete space station in the true sense.

In the future, there will not be a few astronauts living and working on this space station, but more than ten or even dozens of them. "

All the engineers and experimenters in the space station research and development project suddenly fell silent when they heard Gu Qing's words.

Even the project leader Yang Shixiong, who was high-spirited just now, turned to thinking.

After asking Gu Qing for instructions, he also walked to the console, stared at the data on the display screen and the dynamic diagram of the space station simulation, and then said: "Tiangong, open the experimental projection simulation."

"Hello, doctor, the experimental simulation projection has been turned on."

On the operating table, bright lights flashed, and then they gathered into bright models of space stations.

Everyone saw that during the experimental simulation, after the cargo compartment left the space station, with the help of the auxiliary robotic arm on the node module, the Kyushu Space Station experimental module turned 90 degrees and docked with the main body of the space station again.

When the other core module vacated its position, there was another experimental module, which was connected to the main body of the space station using axial rendezvous and docking.

Still with the assistance of the node cabin's auxiliary mechanical arm, it rotates 90 degrees in the other direction and connects to the side interface of the node cabin.

A series of dynamic construction processes of the space station are presented to the public very intuitively.

But even so, if ordinary people or experts from other industries looked at this series of "fancy" operations, they would probably be dazzled. However, in the eyes of everyone in the laboratory, these operations are extremely precise and even precise.

From a series of issues such as the force and speed of docking of various equipment, timing of docking, orbit calculation, attitude adjustment, engine output power, etc., the intelligent AI program Tiangong followed the progress of the space station construction and work and marked the formulas. and data.

A closer look shows that this set of procedures is very logical in terms of the construction time and space docking of the spacecraft. It is almost an advanced and optimized version of the official standard answer of the Daxia Space Station.

But this is not enough.

Yang Shixiong frowned more and more as he looked at the details of each docking and the subtle deformation of each interface caused by the impact.

From time to time, he would think of what Gu Qing had just said: In the future, there will not be a few astronauts living and working on this space station, but more than ten or even dozens of them.

This means that what he is designing now is not an ordinary car or ship, but a "home" that puts dozens of people into the harshest environments and allows them to survive and live.

If a car is involved in a car accident, the main frame and airbags serve as the final protection. If something goes wrong with a ship, plane or other means of transportation, you can still jump off the ship or skydive.

But if something goes wrong with the space station in outer space, if those astronauts do not take the rescue capsule in time, they will have to wait for subsequent rescue on the ground in a harsh space environment without air and water.

"The T-shape is suitable for Daxia Space Station, but it may not be suitable for our Kyushu Space Station. Maybe we can start from this aspect. After all, important parameters such as the main body weight of the space station and the equipment used are inconsistent between us and Daxia Space Station."

Zhou Yu's words were like a bolt from the blue that woke up Yang Shixiong and other engineers.

Before that, they were all good students and wanted to make good use of the company's resources as soon as possible to successfully design the space station.

But it is precisely because the resources are too abundant, the treatment is too generous, and there are also previous homework of the Daxia Space Station to copy. When they designed the shape of the space station, although they designed some other shapes and docking methods, they finally chose the safe one. "Follow the seniors."

Not only Yang Shixiong began to choose other designs, but other engineers and experimenters in the laboratory also began to busy themselves with their own work. Some engineers who were mainly responsible for the structural design of the space station even scratched their heads and frowned.

Gu Qing's eyesight has already exceeded the limits of ordinary humans.

He could clearly see the eyelashes of these engineers and experimenters falling off as they kept blinking...

The eyelashes can fall out like this, and the hair that is restrained by the experimental hat is probably...

Beside him, Yang Shixiong finally chose the project he originally wanted to do after a period of tangled choices.

Circles of circular light spots form a space station with several circular rotating structures.

It's very sci-fi and very beautiful. Gu Qing can even imagine the scenery of this space station becoming a huge spiral in orbit.

But Yang Shixiong frowned and murmured to himself: "This rotating structure composed of several rings is very good, and can even reduce losses in some cases, but there is a big problem that cannot be solved by the dynamic balance of the space station. .

Astronauts' experiments and life inside the space station, vibrations caused by operating equipment, and changes in materials inside the cabin will change the mass distribution of each ring. Especially in space, a small weight will affect the attitude stability of the spacecraft.

Moreover, the longer the radius of the rotating body of the toroidal space station, the greater the moment, and the greater the dynamic balance problem.

According to the original idea, in order to have the ability to adjust mass distribution in real time, the cabin structure of the annular rotating body can be divided into several cabin sections. Each cabin section has ballast water and ballast modules that can be used to adjust mass distribution. Even a gyrocorrector.

When an astronaut moves toward one of the cabin sections, ballast water will be extracted from the ballast water tank of this cabin and injected into the ballast water tank of the opposite cabin to maintain an overall balanced mass distribution - —Similar to using counterweights to adjust the dynamic balance when doing dynamic balancing of car tires.

However, the movements of astronauts can be controlled, but it is impossible to precisely control the astronauts' experiments, private lives, vibrations caused by operating equipment, and changes in materials in the cabin.

No, it can't be done at this stage. "

After shaking his head crazily, Yang Shixiong found the blue star international space station design drawings from a pile of design drawings that were almost scrapped.

He moved his hands and placed it on the operating table, allowing countless light points to gather together to present the design drawings and operational simulation scenarios of the International Space Station one by one.

"The overall design of the International Space Station adopts a truss-mounted cabin structure. Just like a tree, there is a thick truss as the basic structure. The pressurized cabin and other service facilities are attached to the truss to form a truss-mounted cabin structure. space station.

Mao Xiong’s original multi-functional module was docked with their service module, experimental module, life support module, American experimental module and other orbital facilities through the docking module and node module, forming the core part of the space station.

The other part is on the American truss structure, which is equipped with UC’s teleoperated robotic arm service system and space station extravehicular equipment. Four pairs of large solar cell sail panels are installed at both ends of the truss. These two parts cross vertically to form the dragon skeleton.

From a design perspective, this indeed enhances the rigidity of the space station and is conducive to astronauts' out-of-vehicle assembly and maintenance.

However, the International Space Station has too many components, all of which were developed by partner countries. Although it seemed very advanced at the time, the technology was too scattered, which caused maintenance troubles.

And due to the failure of various equipment, the International Space Station is likely to quickly disintegrate and cause an avalanche.

This is not advisable. "

Scratching my head, thinking.

I came up with a solution and then rejected the plan.

Another plan was found, but it was abandoned because it could not be advanced.

Gu Qing patiently watched Yang Shixiong and other engineers and experimenters in the laboratory scratch their heads and heads. Seeing that they were still immersed in the ocean of thinking, Gu opened Tiangong's archives and searched for the experimental logs.

The experiment logs of other university laboratories and corporate laboratories may have been tampered with, but there is no possibility of tampering with the laboratory experiment logs of Jiuzhou Technology.

After all, all experimental projects are under the supervision of intelligent AI. No black box operation in any corner can be concealed from the round-the-clock monitoring of the three intelligent AIs of Xuanwu, Tiangong, and Haizhi. Even if it is concealed, it will be because of video evidence. Deficient and marked by AI.
