Chapter 1388 Design Structure (4K)
Yang Shixiong, the leader 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.
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.
It was just because of some problems and mistakes that Gu Qing corrected some ideas. But when it came to the space station project that 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 ships Airships and cargo ships transport cargo back and forth
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 does not need He devotes himself to everything by himself, like this elder Xia Aerospace Group has hired elites and 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 it. Come up with the best core cabin as the foundation.
The thrust of the JZ-404 launch vehicle is very excellent 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 compartment is docked and the other test module is docked, after the three modules are combined, astronauts complete the space mission and leave the space station. They need to separate the second core module, then go around behind the first core module, and then go around again. Go below the first core cabin and conduct 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 is 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.
One round-trip transportation of materials from the core cabin to the cargo cabin.
At this point, the task of verifying the key technologies for the construction of the Jiuzhou Science and Technology Space Station has been completed. ”
After Yang Shixiong, the head of the space station R&D 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, including space station 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. For difficult problems, the corresponding answers can be found within Jiuzhou Technology.
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’ true identities are unknown to anyone, and the president of Jiuzhou Technology, Gu Qing, are all under the jurisdiction of these four forces.
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.
Project leader Yang Shixiong and other experimenters saw Gu Qing's figure and 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 and stared at the data on the display screen and the dynamic graphics of the space station simulation. , asked: "A one-hundred-ton space station, as far as I know, Daxia Space Station The 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 with the front end of the spherical node module of the first core module. For interface connections, this design is 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 being completed, the Kyushu Space Station also contains four complete functional compartments: core module, cargo module, 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 operating table, 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 gathered into bright spot models of the space station.
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.
With the assistance of the auxiliary mechanical arm of the node cabin, 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 everyone in an extremely intuitive way.
But even so, if ordinary people or experts from other industries looked at this series of "fancy" operations, they would probably be dazzled. But in the eyes of everyone in the laboratory, these operations are extremely precise and even It's 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.
Looking closely, this set of processes 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.
When 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-shaped shape is suitable for the 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 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 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, In the end, I chose to play it safe and "follow the seniors."
Not only Yang Shixiong began to choose other designs, but other engineers and experimenters in the laboratory also began to be busy with their own work. Some engineers who were mainly responsible for the structural design of the space station even scratched their heads and frowned. Lock tight.
Gu Qing's eyesight has already exceeded the limits of ordinary humans.
He clearly saw the eyelashes of these engineers and experimenters falling off while 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 what he originally wanted to do after a period of tangled choices. project.
A circle of ring light spots forms a space station with several ring rotating structures.
It is very sci-fi and very beautiful. Even Gu Qing can already 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. , the space station dynamic balance cannot be solved
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 torque, 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, and each cabin section has a pressure that can be used to adjust the mass distribution. Tank water, ballast modules and even gyro correctors.
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 The overall mass distribution is balanced - similar to using weights to adjust the dynamic balance when doing dynamic balancing of car tires.
However, the movements of astronauts can be controlled, but the astronauts’ experiments, private lives, vibrations caused by operating equipment, and changes in materials in the cabin cannot be precisely controlled at all.
No, it can't be done at this stage. ”
After shaking his head crazily, Yang Shixiong found the blue star international space station design drawing from a pile of design drawings that was about to be scrapped.
He moved his hands and placed it Go to the operating table, let countless light points gather together, and combine the design drawings of the International Space Station and The operation simulation scenes are presented one by one.
“The overall design of the International Space Station adopts a truss cabin structure, which is like a tree with a thick truss as the basic structure, pressurized cabin and other components. Various service facilities are anchored on the truss to form a truss-mounted space station.
Mao Xiong’s original multi-functional module was docked with their service module, experimental module, life support module, America 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 point of view, this indeed strengthens 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, causing 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 figured out a way, but then rejected the plan.
Another plan was found, but it was abandoned because it could not be advanced.
Gu Qing very 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. Experiment log.
The experiment logs of other university laboratories and company laboratories may be 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 hidden from the round-the-clock monitoring of the three intelligent AIs of Xuanwu, Tiangong, and Haizhi. Even if it is hidden, it will be because of video evidence. Deficient and marked by AI.
