Vol 2 Chapter 1026: 【Superconducting maglev space shuttle vehicle】

Spring will start in 2O24.
Luo Sheng's first inspection trip after the New Year's Day came to the southern peak of Taihua Mountain, the most dangerous mountain in the world, which is also the highest peak of Taihua Mountain.
Nanfeng has been closed to the outside world for nearly three years, and it has not yet been opened to the outside world. Visitors to Taihua Mountain can only watch from afar.
The reason is that Star Arrow International has contracted the entire South Peak for the superconducting suspension orbit test of the space ladder. This is the experimental research center.
At 15 o'clock in the afternoon of the same day, a train drove into the foot of the southern peak of Taihua Mountain, Luo Sheng got out of his special car, and the assistant of the bionic human sister Zhi Linya who was accompanying him also followed him.
"Let's go!"
Luo Sheng and others immediately walked towards the destination. Nanfeng now has a unique wonder. On the steepest peak there is a straight metal steel frame that is towering into the clouds and perpendicular to the ground. The parallel special cables are the cables used by the ladder, and the distance between the two cables is about 1.5 meters wide.
The height of the drop has reached an astonishing 2,000 meters, which is basically the same as the height of the southern peak of Taihua Mountain.
Numerous low-rise buildings dedicated to experiments have been built at the foot of Nanfeng. These buildings are not intended to be demolished later. With the end of the experiment here, they will open up as a brand-new tourism project in the future many years later.
"Mr. Luo, fortunate enough to meet, welcome to come and inspect!"
Luo Sheng came to the experimental center. Deng Zigang, the chief technical expert here, brought a few people out to receive.
Deng Zigang is an expert who has devoted himself to high-temperature superconducting maglev technology for more than 20 years. He led his team to complete the first manned high-temperature superconducting maglev test line in China 21 years ago. The field of maglev trains has made great progress.
But ten years ago, he was invited by Star Arrow International to tackle a project that was even more exciting for him. He participated in the space ladder orbit high-temperature superconducting maglev project. So far, it has been a ten-year-old project.
"Lao Deng, directly deliver the dry goods?" Luo Sheng said with a smile, without being muddled at all.
"Haha, I can't ask for it, please here." Deng Zigang stunned for a while and said with a laugh, and immediately led Luo Sheng and others to a large low-rise building where the simulated vertical track runs through the foot of the mountain.
"Lao Deng, before the room temperature superconducting material is produced, the ladder needs your high temperature superconducting maglev technology, pulley... I don't think it is reliable." Entering the empty building, Luo Sheng said with a smile .
"Fortunately, it's not a shame, Star Arrow International has smashed hundreds of billions and there is no white flower." Deng Zigang was full of confidence, and immediately explained to his team and ordered to show Luo Sheng their results.
Looking around, Luo Sheng saw that when the vertical parallel cable track extended to the interior of the building, it turned into a curved half-sided "U" shape, and the track also extended to the ground, changing from vertical to horizontal.
Looking along the cable parallel track, I saw a special vehicle parked on the track. Both sides showed a streamlined bullet, like a mini high-speed rail locomotive.
"Mr. Luo, the team members are filling the space shuttle vehicle with refrigerant." Deng Zigang briefly introduced, but he didn't say much. He knew that Luo Sheng was different from other leaders. He was engaged in high-tech. Need to explain too much.
Space shuttle vehicle, this vehicle is an experimental version.
As the name suggests, in the future, the space ladder cable orbit will rely on this kind of shuttle vehicle to travel from the ground tower base to and from the orbiting space station, or carry people or cargo.
The future use is much larger than the experimental version.
After a while, after several staff filled the shuttle vehicle with a large amount of liquid nitrogen refrigerant, a magical scene appeared. The shuttle vehicle that was originally pressing on the cable track floated easily without the help of other external forces. The height is 22 mm.
"When it is suspended, we can suspend it in the range of 10 mm to 30 mm according to its needs, but according to our general experience, 22 mm is the best." Deng Zigang introduced.
At first glance, it looks like it is attached to the track cable, but it has actually been suspended, and the shuttle vehicle can be seen floating slightly to the naked eye, but it is always stable in a range.
It is worth mentioning that since the day when the superconductor was discovered, the goal of mankind was to discover as much as possible a material that works in an environment closer to normal temperature.
Cryogenic superconducting maglev technology generally requires liquid helium to reach the required temperature, and liquid helium is a precious resource. Cryogenic superconducting requires such a low temperature, so liquid helium can only be used. To put it bluntly, it is too expensive.
Liquid nitrogen is cheaper, and the temperature that can be reached is naturally not as low as liquid helium, but the price is cheaper, and high-temperature superconductors do not need the low temperature of liquid helium, so liquid nitrogen is used for high-temperature superconductors, which is more economical than liquid helium. The amount of liquid nitrogen is less than a thousand pieces.
As for normal temperature superconductors, the current level of technology has not yet been settled.
Luo Sheng came to the shuttle vehicle, and after looking at it for a moment, he stretched out his hand and pushed hard toward the extension of the track. The suspended shuttle vehicle was pushed out for a certain distance, and returned to its place magically when Luo Sheng regained his strength.
The shuttle vehicle seems to be nailed to the track. This is a unique magnetic flux pinning effect, which shows a restoring force. It is this restoring force that ensures that the shuttle vehicle will not derail and needs to exceed the threshold of the restoring force. The value will derail, which also means that it can be hung on the track.
The stability of the orbit like a nail and the 360-degree levitation have given the high-temperature superconducting magnetic levitation unique advantages, and it is suitable for the space-to-air shuttle of the space ladder carrier.
In fact, people are familiar with magnetic levitation for a long time. There are several maglev trains in China that use electricity to magnetically levitate above the track. Of course, they are currently out of service.
However, this high-temperature superconducting maglev vehicle does not use electricity to achieve levitation. This is simply a boon for the space ladder. It can greatly reduce power consumption. This is also inseparable from the superconducting materials and liquids developed by Deng Zigang. Nitrogen refrigerant, liquid nitrogen at minus 196 degrees Celsius is the refrigerant for high-temperature superconductors.
The high temperature in high temperature superconducting is not hundreds or even thousands of degrees, but an unimaginable minus 196 degrees Celsius. The reason why it is called high temperature is because there is also a kind of low temperature superconductor. The refrigerant used is liquid helium. It is minus 269 degrees Celsius, which is much lower than the temperature of liquid nitrogen.
However, the addition of liquid nitrogen refrigerant is not enough to suspend the vehicle. The high-temperature superconducting material is the key to suspending. The high-temperature superconducting material developed by Deng Zigang is not an ordinary ceramic material in a low-temperature environment. It is colorless and tasteless. Without any magnetism, superconductivity will occur once in a low temperature environment.
"Professor Deng, take this car to the top of the mountain together?" Lu Ming, who was standing next to the vehicle, immediately invited Deng Zigang, who was stunned and immediately accepted it with confidence.
Lin Ya, who was accompanying, hesitated for a while when he heard this, she was a bionic, but she couldn't violate Luo Sheng's instructions.
Seeing Luo Sheng and Professor Deng Zigang enter the shuttle vehicle, several staff members immediately went in to assist them in taking safety protection measures, including as if they had checked the seat belts, and the other team on the other side immediately began to review to ensure that nothing went wrong.
If something happens to the two big guys inside, the global economy will explode in place.
"Lao Deng, in the post-solar storm era, a hundred wastes are waiting to be developed. It is a historical opportunity to comprehensively update and upgrade urban rail transit. I intend to take the lead in applying this technology to urban rail transit and promote it on a large scale. I started to do the pilot, and when I turned back, I would go to the city leader to talk about this matter." Luo Sheng turned his head and smiled at Deng Zigang, who was sitting next to him.
The breakthrough of high-temperature superconducting technology is definitely not only applied to the space ladder, but also the transformation and upgrading of urban traffic is promising, and there are too many areas where it can be used.
"You don't need to ask me about this kind of thing, I'm only responsible for development." Deng Zigang smiled. After a while, his team sent a message that everything was ready. Deng Zigang suddenly said: "Xiaohua, take us to the top of the mountain!"
[Ok, the shuttle will start in fifteen seconds]
The artificial intelligence on this vehicle responded to Deng Zigang's instructions. There is no doubt that this is of course the application of artificial intelligence technology under the Cote d'Azur.
Fifteen seconds later, the shuttle vehicle began to steadily and orderly accelerate along the horizontal cable flat track. Luo Sheng sitting in the shuttle did not feel heavy bumps, nor did he feel on the waves. It was very stable. .
As the shuttle vehicle continued to accelerate, the originally horizontal track gradually began to climb, and finally left the low building on the ground, Luo Sheng also saw the exterior scene.
At this moment, the shuttle carrier has maintained vertical to the ground, and continues to accelerate upward along the cable track.
The shuttle carrier is very stable on the track like a nail.
On the way, Luo Sheng turned his head and asked Deng Zigang: "Old Deng, how many kilometers per hour can the maglev vehicle applied to the ladder reach the fastest speed?"
