"What about speed?" The core question is this, and everyone is very concerned about it.
"If you don't consider the distance, four thousand kilometers is no big deal."
"What the hell are you talking about? Hurry up and stay stunned!"
"Fuck!"
"What the hell?"
This speed simply stunned everyone, this is too awesome.
"Don't look like this, we have to consider the endurance of the human body. If the distance is hundreds of kilometers, the top speed can reach 3,000 kilometers per hour, but it will soon have to slow down."
"What are the acceleration and deceleration distances?"
"It takes five kilometers, which is longer than the acceleration time of an airplane. After all, we have to consider the endurance of the human body."
"It's okay."
At the summary meeting after the experiment, Chen Xiao listened quietly for a while and understood. Later, he read the report and learned more details.
The model test run was very successful, so the next step is the actual vehicle test.
The production line was officially launched, and everything was produced according to actual specifications. Chen Xiao was unsure. The difference between the model test run experiment and the computer model calculation was less than 5%. This accuracy rate is quite amazing. Now that we have the data from the model test run,
Through computer calculation and derivation, the actual vehicle success rate is over 80%.
This ratio is really not low. A real car is not just a small model that is enlarged to the same proportion. Some things have completely different concepts when they are small and when they are big.
The bigger something is, the different rules it will adapt to, and there will be many things to pay attention to.
For small shapes, don’t pay too much attention to safety. For big shapes, you need to take more protective measures.
To take the simplest example, the performance of an aircraft model in a wind tunnel is not exactly equal to the flight performance after it is manufactured. Both low-speed wind tunnel and high-speed wind tunnel data must be taken into consideration.
Now that the tube bundle channel has entered actual production and installation, we have to consider what kind of environment such a large size will face.
In addition to normal atmospheric pressure, we also have to face the most extreme environments of strong winds, flash floods, mudslides, lightning strikes, fires, hail, and even avalanches and landslides.
After the real restraint channel was established, the test team launched the most brutal and inhumane test. They would be perverted in whatever way they wanted. If they failed to do anything during the test, when disaster struck, it would not be a matter of severity.
The control channel was like Sun Wukong being captured by heaven, and all kinds of torture were used. Lightning strikes were simulated with ultra-high-voltage current, and napalm was directly applied to the fire. The kind that stuck to it and couldn't be shaken off was even taken out.
An acetylene gun is used to attempt to cut the tube bundle channel.
The compression test was conducted using high-altitude heavy objects. The five-ton iron block fell down with a "clang". Later, it became unsatisfactory and the noose was used to accelerate the fall and hit directly.
The movement was so loud that it was frightening to watch, and even if heard from a distance, it was scary.
At the beginning, the tube bundle channel really failed to withstand it, and it dried up and cracked after dozens of impacts. This had to be done from scratch, starting from the diatom selection stage.
Some people raised objections to this matter.
"Are the requirements of Changtian Technology too high? Dozens of times, a five-ton iron block accelerated and fell from a height of 30 meters. Is there any material in the world that does not deform?"
"Yes, acetylene is used for cutting. The temperature is three to four thousand degrees, and even ruthless people like the rails can't stand it."
"It's not that it's not good to be cautious, is it too cautious? Under what circumstances could such a heavy thing fall down? A meteorite? The probability is too low. If it is near the control channel, it must be fenced like a railway. It is not possible at all.
A car will hit you directly."
Everyone is complaining, but from the bottom of my heart I admire Changtian Technology very much. Either don't do it, or build the best one, and don't launch it until it reaches the best level. After it was launched, it still continued to improve. It's no wonder that their products
Such good things are all achieved little by little.
After several attempts, the tube bundle channel finally successfully withstood various expected impacts. According to estimates, even a ground-penetrating missile could not break the armor of the tube bundle channel. It was not until this point that Chen Xiao passed the construction of the actual test run tube bundle channel.
The diameter of the tube bundle channel is five meters. When building it, one-third was sunk to the bottom and filled with sand, one-sixth was built for rails, and the remaining half was left for the car. The floating distance of the entire car was actually less than five centimeters, and it floated too high.
It makes no sense. Instead, room-temperature superconducting wastes materials and electricity.
There are room-temperature superconducting materials at the bottom of the train and on the rails, which are used to receive the effects of magnetic fields. Above the room-temperature superconducting layer at the bottom of the train, an insulating layer is laid to isolate the electromagnetic influence. After all, it is not healthy for the human body to stay in a strong magnetic field environment for a long time.
Electronic equipment is also prone to damage.
As for the power supply and equipment operation of the train itself?
You don’t have to think about it at all! There is a strong magnetic field, but you are still worried about not having electricity?
Who said this? Faraday can jump up and hit people. As long as the strong magnet is converted into electricity under the car, it can supply the entire car.
Communication during driving is not a problem. Positioning devices and signaling devices can be installed next to the railway tracks, and the trains can receive them while driving.
The entire pipe bundle channel has a rolling gate at regular intervals, which is similar to the water barrier of a ship. If there is a leak somewhere, both ends must be quickly sealed to isolate the exposed area.
You can't have thousands of kilometers of pipelines without a single gate, right? If something breaks, the entire channel will be filled with air.
This kind of gate is also made of diatom shell material, which is very tough and soft.
The control channel is within the Xia Kingdom, and the distance between the gates can be farther. After all, the security is very good, and everyone does not have powerful weapons. If it is built with foreign aid, the distance must be shortened.
In a more dangerous place, you might have to spread out mayflies and combat drones for full control.
Don't think too well of people's minds. There are people everywhere who don't eat pork and will blow themselves up, so it's better to eat pork.
The tube bundle channel for the actual vehicle test was quickly built. It is only one kilometer long, but it is circular and fully enclosed. In this way, unlimited test runs can be carried out without worrying about distance.
On the day of the test drive, Chen Xiao came to the scene in person, which made everyone quite nervous. The immortal scientific experts in the virtual world Yunxia District watched the live broadcast neatly, and they were as obedient as they could be.
Chen Xiao walked into the tube channel and walked along the one-kilometer channel. The smell inside was a bit complicated. It was roughly the smell of cars and equipment plus the channel itself. Countless equipment had their indicator lights on.
Everything seems so sci-fi.
The train just lay there quietly. Compared with ordinary trains, the trains at this time are larger and can carry more people. In the future, they will use magnetic levitation. There is no friction. Don’t worry about not being able to pull people. The train itself
It's still white and looks just like an ordinary high-speed rail.
When Chen Xiao left, a group of people followed him. They didn't dare to disturb him. The boss was inspecting, so don't be so blind.
As the initial command was given, the train began to levitate off the track, then accelerated, and soon reached a speed of two thousand kilometers, then two thousand one, two thousand two, and finally broke through to four thousand kilometers.
"Great!"
"It was a success!"
"Scared me!"
The self-made tube channels in the diatom shell are translucent, but people outside can't see what's inside. The train is too fast and there's no time to react and the eyes can't keep up.
Subsequently, a lot of data came from the dummy in the train. This is the most realistic feeling of the human body. Everyone is fine, but it is still a bit unfriendly to children and the elderly. When it is put into operation later, the maximum speed is stipulated to be
Three thousand kilometers, after all, the cost is not the optimal solution at a speed of 4,000 kilometers per hour.
Running too fast will impose too much thrust and resistance, which will also cause damage to the vehicle itself and the room-temperature superconducting materials. You can’t just drive it for a day and have to maintain it once, right? This is not environmentally friendly. After rigorous calculations, three thousand kilometers is the best
It can take advantage of speed and at the same time have the lowest loss. Both acceleration and deceleration are suitable for humans, just like ordinary high-speed rail.
"The test drive experiment was successful!" Chen Xiao personally announced the results, and everyone's suspense dropped and they began to cheer. This time, the experiment was all done for real, and even the way to get on and off the car was considered.
When parking, a pipe will extend from one side of the car body and directly connect to the wall of the tube channel. Then once the door is opened, passengers can get on and off very quickly. During this process, the fully enclosed car body itself will also conduct rapid air exchange, and the gas will flow from everyone.
It flows over the top of the head without making people feel uncomfortable.
The next step is to conduct an impact test on the built straight section of the tube bundle channel. The tube bundle channel said: "You can't let me go just by riding a horse? How many times have you tested it?"
But this is the first impact under actual circumstances, so you have to do it if you don't want to.
The reason is very good. This one-kilometer section of pipe channel is connected from front to back, which may far exceed the performance of a straight line arrangement. It makes no sense to bump into that one. But we still have to bump together.
This time the test was even more severe, with a ten-ton discus thrown directly downwards at an accelerated speed.
The shock wave shook everyone around, as if a magnitude 8 earthquake was coming.
As a result, the tube channel was fine.
The next step is to test the load-bearing capacity. The weight increases from 80 tons to 200 tons. When it reaches 200 tons, the pipe becomes a little dented and small marks begin to appear on it. However, it is quickly repaired with tentacle-like things and becomes
It had to get back to normal. Then, the moment to witness the miracle came, and the dented area slowly returned to its original shape under the weight of the weight.
This is the ability of the new diatom. The fiber tube bundles it has have a certain repair ability. Even if it is pressed in, the fiber tube bundles will pull the silica shell back to its original shape.
This is not the diatom fiber tube bundle at the contact point that is exerting force, but the entire section of diatom that is exerting force and working. This time the experiment is only ten meters, so the repair ability is so powerful.
If the length is longer, the repair ability will be faster, because diatoms in further areas will support and reproduce themselves. Don't always think that the entire tube channel is dead, it is actually in a semi-alive state.
It's just that it's quiet at ordinary times, and can repair itself when something goes wrong. The source of nutrients is also very simple, that is, the substances in the soil, sunlight, and water can nourish it.
Assuming that the fiber tube bundle is built in the dark, or in a hot and dry desert, then diatoms in other areas will automatically come to replace the diatoms here, just like a flowing water source. There is no need to worry about the tube bundle channels in these places collapsing.
Besides, even in a desert, it always rains, right?
Under the desert, there is moisture and salt. How can we not find nutrients on diatoms? Although undersea tunnels are troublesome, there is no solution. This kind of place can use light internally. Diatoms themselves come from the sea. So
It is equivalent to simulating sunlight, and the diatoms outside the tube channel can renew themselves. If there is no damage, there is generally no need to activate the diatoms.
Everything is done through biological methods, which is most in line with the taste of Changtian Technology.
After the test, Changtian Technology published a related paper. Among the co-published authors, all the big names in virtual immortality were included, and their names were listed in alphabetical order.
The personnel responsible for solving each key technology are also listed.
Due to confidentiality requirements, only the name of Yongsheng Daniel was released.
The personnel of Changtian Technology are still alive and should not be missed.
This makes Daniel very happy. He is really so glorious after death. Isn't this the meaning of applying for virtual immortality?
This time to solve the vacuum maglev tube tunnel train project, Chen Xiao had to sigh, virtual immortality is so right! There are so many experts, it is really easy to do things.
It has only been two months, and everything has been completed. If there are more talented people, the progress will be faster and faster in the future.
Chen Xiao feels that she is still the same group of people who loved collecting.
When I was a kid, I collected stamps, Raccoon Instant Noodles dinosaur cards, then Water Margin cards, and then Three Kingdoms cards. When I got older, I collected star cards and Ultraman cards. When I got older, I collected SSR cards while playing games. And now here we are.
, collect scientists’ awesome cards.
After the paper was published, everyone was shocked not that the dead big cow lifted the coffin and wrote the paper, but that this thing was so fast!
"Damn it, at 3,000 kilometers per hour, it only takes me an hour to get from the capital to the southern seaside. I drink soybean juice in the morning, so I can have seafood for brunch!"
"Three thousand kilometers is a speed that applies to everyone, and the limit speed is four thousand kilometers. If everyone is young, they can experience this pushing feeling."
"I have an idea. Otherwise, if we put the training of astronauts and pilots in this kind of pipeline, the cost should be cheaper than the simulation warehouse, right?"
"Haha! A long-distance relationship is a deal breaker, but the commuting time is a deal breaker! I can even live in my hometown and go to work in a big city, so I don't have to worry about buying a house in a big city!"
"Eh! That makes sense! If this happens, house prices will continue to fall, and the house will have no financial properties, and it won't be able to cause trouble even if you don't have to worry about it!"
