Chapter 1388 Design Structure (4K)

Yang Shixiong, the person in charge of the space station R&D project and one of the top engineers of Jiuzhou Technology, is now "high-spirited" in the laboratory.

Previously, considering the high cost of living in the space station, he developed a regenerative life support system tailored for astronauts under the premise of ensuring safety and health.

However, due to some problems, some mistakes occurred, so Gu Qing corrected some of his ideas, and when it came to the space station project that he was best at, it was already in another state.

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

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

Looking at the sketch drawn by the other party, and Tiangong's explanation and optimization project on the side, Gu Qing only felt-relaxed.

Blue Star has talents, and it does not require him to do everything with all his heart. This elite who was recruited from Daxia Aerospace Group can answer many questions.

"If we want to build an excellent space station, what we should do most 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 carrier rocket is very excellent, which can fully support us to design a larger core module and launch it into orbit safely.

Then the JZ-405 carrier rocket can carry the supply cargo cabin and dock with the docking port of the core cabin, and then fly together in orbit. This process is axial rendezvous and docking, just like two track and field athletes handing over the baton on the runway.

In my opinion, docking is easy, but leaving is difficult.

After the cargo cabin docks and the other test cabin docks, and the three cabins are combined, the astronauts need to separate the second core cabin when they complete the space mission and leave the space station, then go around behind the first core cabin, and then go around to the first core cabin. Below the core module, radial rendezvous and docking verification is carried out.

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

…

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

Whether it is leaving the space station and returning to the blue planet. Or the ground JZ series rocket autonomously flies around to the front of the core module to dock, the robotic arm is needed to assist in the transfer.

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 module and the cargo module, the materials are transported back and forth once.

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

After Yang Shixiong, the person in charge of the space station research and development project, finished explaining this process, the laboratory rang with warm applause.

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

Because from the construction materials of the space station, polymer materials, special insulation materials, radiation protection materials, robotic arms, docking technology, space station systems, space station electronic equipment, chips, launch vehicles and other problems that need to be overcome, Jiuzhou Technology can find the corresponding answers.

Another reason why Yang Shixiong can serve as the person in charge of the space station R&D project is that he has a lot of "bosses" above him.

The head of Jiuzhou Technology Titanium Star Department, the head of the semiconductor department, the Jiuzhou Technology think tank whose members' true identities are unknown, and Jiuzhou Technology President Gu Qing can govern these four forces.

In a sense, Gu Qing can easily intervene in the progress of the project without going on the road himself, just through other people.

Gu Qing walked into the laboratory when the applause of the crowd became a little smaller.

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 operating table, stared at the data on the display screen and the dynamic diagram of the space station simulation, and asked: "A 100-ton space station, as far as I know, the Daxia space station is 50 tons.

When our Jiuzhou space station's second core module was launched, it was so big that for safety, it adopted axial rendezvous and docking, and connected with the front docking port of the spherical node module of the first core module. This design is very good.

But have you thought about the docking of the final four modules in the future? What should we do with the reaction force generated when they dock again and again?

Every time we have to stand Do we need to adjust the attitude adjustment engine?

In the short-term mission time, according to the working life of the attitude adjustment engine and wireless array thruster we designed, there may be no problems within 20 years, but what about 20 years later?

It should be noted that after the completion of the Kyushu Space Station, it also includes four complete functional cabins: the core cabin, the cargo cabin, the experimental cabin, and the manned spacecraft. It is a truly complete space station.

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

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

Even Yang Shixiong, the project leader who was high-spirited just now, turned into a thoughtful expression.

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

"Hello, Doctor, the experimental simulation projection is turned on."

On the operating table, there was a flash of light, and then gathered into a bright spot model of the space station.

Everyone saw that in the experimental simulation, after the cargo cabin left the space station, with the help of the auxiliary mechanical arm on the node cabin, the Jiuzhou space station experimental cabin turned 90 degrees and docked with the main body of the space station again.

When another core cabin vacated the space, there was another experimental cabin, which was docked to the main body of the space station using axial rendezvous.

With the assistance of the auxiliary mechanical arm of the node cabin, it rotated 90 degrees in another direction and connected to the side docking interface of the node cabin.

A series of dynamic construction processes of the space station were presented to everyone very intuitively.

But even so, if ordinary people or experts in other industries were to see this series of "fancy" operations, they would probably be dazzled long ago, but in the eyes of everyone in the laboratory, these operations are extremely precise and even accurate.

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

Looking carefully, in terms of the construction time and space docking of spacecraft, this set of processes is logical, and it is almost an advanced optimized version of the official standard answer of the Daxia Space Station.

But this is not enough.

Yang Shixiong looked at the details of each docking, and the slight deformation of each interface caused by the impact, and his brows were more and more furrowed.

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

This means that what he is designing now is not an ordinary car or ship, but a "home" that puts dozens of people in the worst environment for them to survive and live.

If a car has an accident, the main frame and airbags are the last guarantee. If there is a problem with a ship, airplane or other means of transportation, you can jump off the ship or parachute.

However, if there is a problem with the space station in outer space, if the astronauts do not take the lifeboat in time, they can only wait for subsequent rescue on the ground in the harsh space environment without air and water.

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

Gu Qing's words woke up Yang Shixiong and other engineers like a bolt from the blue.

Before this, they were all three-good students, thinking about making good use of the company's resources as soon as possible to successfully design the space station.

But it was precisely because the resources were too abundant, the treatment was too generous, and there was also the previous Daxia Space Station's homework 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 "follow the predecessors".

Not only did Yang Shixiong start to choose other designs, but other engineers and experimenters in the laboratory also began to work on their own. Some engineers who were mainly responsible for the structural design of the space station were scratching their heads and frowning.

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

He clearly saw the eyelashes of these engineers and experimenters falling off in their blinking...

If eyelashes can fall like this, then the hair bound by the experimental hat may also...

Beside him, Yang Shixiong finally chose the project he wanted to do in a tangled choice.

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

It was very sci-fi and beautiful. Gu Qing could even imagine that this space station would become a huge spiral landscape in orbit.

However, Yang Shixiong frowned and muttered 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, the dynamic balance of the space station cannot be solved.

The experiments and life of astronauts inside the space station, the vibration caused by operating equipment, and the changes in materials in the cabin will change the mass distribution of each ring, especially in space, where a tiny weight will affect the stability of the spacecraft.

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

According to the original idea, in order to have the ability to adjust the mass distribution immediately, the ring rotating body The cabin structure can be divided into several compartments, and each compartment has ballast water, ballast modules and even gyroscope correctors that can be used to adjust the mass distribution.

When an astronaut moves to one of the compartments, ballast water will be drawn from the ballast water tank of this compartment and injected into the ballast water tank of the opposite compartment to maintain the overall mass distribution balance - similar to using counterweights to adjust the dynamic balance when balancing car tires.

However, the movement of astronauts can be controlled, but the experiments, private life, vibrations caused by operating equipment, and changes in materials in the cabin cannot be accurately controlled.

No, it cannot be done at this stage. "

After shaking his head frantically, Yang Shixiong found the design of the Blue Star International Space Station, which was about to be scrapped, from a pile of design drawings.

He placed it on the operating table with his hands, allowing countless light spots to gather together, presenting the design of the International Space Station and the operation simulation scenes one by one.

"The overall design of the International Space Station adopts a truss-mounted cabin structure, just like a tree with a thick truss as the basic structure, and the pressurized cabin and other various service facilities are hung on the truss to form a truss-mounted cabin space station.

The original multifunctional cabin of the Russian bear docked with their service cabin, experimental cabin, life support cabin, American experimental cabin and other orbital facilities through docking cabins and node cabins to form the core part of the space station.

The other part is on the truss structure of America, which is equipped with a large remote-controlled robotic arm service system and space station extravehicular equipment, and four pairs of large solar panels are installed at both ends of the truss. These two parts cross vertically to form a keel.

From a design point of view, this does strengthen the rigidity of the space station, and is conducive to astronauts' assembly and maintenance outside the cabin.

However, there are too many components in the International Space Station, all of which were developed by cooperating countries. Although they seemed very advanced at the time, they were also too scattered in technology, which led to maintenance difficulties.

And due to the failure of various equipment, the International Space Station is likely to disintegrate rapidly and an avalanche will occur.

This is not advisable."

Scratching his head and thinking.

I came up with a solution, but rejected it.

I found another solution, but it was abandoned because it could not be promoted.

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

The experimental logs of other university laboratories and corporate laboratories may be tampered with, but the experimental logs of Jiuzhou Technology's laboratories are impossible to be tampered with.

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