Six hundred and seventieth chapters can be called land aircraft
, the reborn tech upstart
It was already afternoon when Ye Zishu came to Huanyu Group. After arriving at the headquarters, Ye Zishu didn't chat with Wang Chuanfu, but went directly to their R\u0026D center.
Whether it is a motorcycle or various automobile products, they are not at the same technical level as the ultra-high-speed maglev train.
In the face of such a complex systematic project, even though Leaf Book provided relatively complete technical information, their R\u0026D personnel encountered many problems.
Due to time constraints, the technical information provided by Leaf Book will briefly describe the less important parts, and describe the key parts in detail, so as to avoid leading the R\u0026D personnel to the wrong way of thinking.
Doing so has indeed reduced the work pressure of Ye Zishu, but it has also caused some troubles for the research and development personnel, especially for the scientific research personnel who are not particularly experienced, it will be a big deal.
If it is an ordinary rail train, quite a few domestic researchers are familiar with it, but there are basically no ready-made talents in China for such an ultra-high-speed maglev train.
These scientific researchers of Huanyu Group are rushing ducks to the shelves, so they can only study the technical information given by Ye Zishu carefully, and then experiment according to their own understanding.
If you understand it correctly, it’s fine, if you understand it wrong, it’s a waste of time, but that’s how scientific research is. Trial and error is the daily work of scientific research, and everyone still understands it very well.
However, Ye Zishu has relatively strict time requirements for the development progress of ultra-high-speed maglev trains. It is best to complete all research and development work by the end of this year and do a good job in the construction of related industrial chains.
This is a lot of pressure for many scientific researchers. In order not to slow down their progress, it has become commonplace to work overtime, and at the same time they are more active in requesting support than before.
Although most of the people who requested support were people with richer internal experience, there were also many problems on Ye Zishu's desk.
So when he came here, Ye Zishu did not gossip casually, but went directly to the R\u0026D center to help the R\u0026D personnel solve the problems they encountered.
He will definitely not accompany the researchers to conduct research, but just explain the problems they encounter and help the researchers understand his intentions.
After the R\u0026D personnel understand, the latter will be done by the R\u0026D personnel themselves, so that the solution to the problem will be faster and save his time.
Fortunately, the real problem is written in detail in the technical information provided. Even where the text description is not detailed, there is a simulation system that gives a panoramic display.
At around 8 o'clock in the evening, the problems encountered by the R\u0026D center were basically solved by him, and he also checked the overall progress here, which was still satisfactory to him.
Huanyu Group is one of the earliest companies to access artificial intelligence-assisted research and development. It started accessing it as early as the end of last year. With this auxiliary system, the research and development efficiency is at least 5 times faster than before.
This is also the reason why he believes that the Huanyu Group will be able to develop the ultra-high-speed maglev train in about a year. Otherwise, due to its complexity, even with his information, he would not dare to think so.
Don't think that the plane is very complicated. In fact, the complexity of the ultra-high-speed maglev train is higher than that of the plane. It is precisely because of its advanced technology that it can reach a stable operating state of 800 kilometers per hour.
The fastest speed can reach more than 900 kilometers, which can be called a land aircraft. In order to ensure high-speed and stable operation in orbit, each supporting system is a master of top technologies.
The first is the energy system. At such a high speed, ordinary pantographs are useless at all. Therefore, it is necessary to develop new high-wear-resistant and super-lubricating pantograph materials.
In order to avoid problems with the power supply system of the pantograph, the ultra-high-speed maglev train itself also has a power generation system, which uses aviation kerosene fuel and a power generation device based on high-efficiency thermoelectric conversion materials.
It is difficult for ordinary power generation devices to be compact and have a large output power, which not only increases their own load, but also
At the same time, it also increases the difficulty of the overall design.
Now that even room-temperature superconductivity has been brought out, he doesn't mind taking out a high-efficiency thermoelectric conversion power generation device. Such a thermoelectric power generation device can be made very small.
Generally speaking, an ultra-high-speed maglev train will carry one ton of aviation kerosene, which is enough to ensure that the train travels to a safe position at a normal speed when there is a problem with the external power supply.
The reason why batteries are not used is because the electric energy stored in batteries per unit weight is too low, and the cost is not low. The best energy storage is chemical fuels.
Coupled with a high-efficiency thermoelectric conversion device, it can ensure an ultra-high energy conversion ratio, and there is no need to worry about excess energy being wasted.
Fortunately, the hourly energy consumption of maglev trains is actually much lower than that of high-speed rail trains. It is only about 80% of the energy consumption of high-speed trains in previous lives. Carrying a ton of aviation kerosene can generate tens of thousands of kilowatt-hours of electricity.
It also means that with one ton of aviation kerosene, the ultra-high-speed maglev train can run for more than one hour, and the ultra-high-speed maglev train can run more than 1,000 kilometers during this time.
It is precisely because the ultra-high-speed maglev train has the characteristics of ultra-low operating costs per kilometer that he treats it as the main solution.
Because this means that for the same distance, the ticket price of the room-temperature superconducting ultra-high-speed maglev train is only half of the previous high-speed rail ticket price, and it can also allow the operating company to obtain more profits.
Of course, these are basic devices. How to ensure the seamless connection between external power supply and internal power supply without waste is also a major problem. This is where the value of system integration lies.
In addition to these problems with the train itself, there are other problems, such as the noise caused by compressed air and friction due to the high speed of the train.
Originally, one of the reasons why he took a fancy to the maglev train was that the noise would be low. Naturally, it was necessary to solve the noise problem caused by high-speed operation, so noise-reducing guardrails would be built on both sides of the train track.
This guardrail can not only reduce the sound, but also help stabilize the train, and even interact with the train, using aerodynamics to make the train more energy-efficient.
The room temperature ultra-high-speed maglev train is a type of train with very high construction cost but low operating cost, which is very suitable for the large population and large geographical area of our country.
Because only a super-high manned frequency can reduce costs, everyone can enjoy lower prices, and the service quality is even higher.
If it is switched to other countries, it is not suitable to use this set of ultra-high-speed maglev trains, which will cause the cost of single-person use to remain high.
If such a transportation network is built on a large scale in China, the role of airplanes will be completely eliminated. The speed will not be slower than that of airplanes, the safety will be higher than that of airplanes, and it will save a lot of trouble by flying.
The most important thing is that the ticket price is also lower than that of the plane. He really can't imagine it. With such a train, why do you still need to fly? Do you feel uncomfortable for yourself?
It is precisely because of this that he feels that the aircraft manufacturing of Huanyu Group can be delayed. In contrast, the ultra-high-speed maglev train is more important.
However, after communicating with the people in the R\u0026D center, they believe that the traditional pantograph is not used for power supply, because the construction of such a power distribution system along the line increases the construction cost.
Since one ton of aviation kerosene can make the train run for about two hours, it is better to simply increase the fuel capacity of the train and expand it to a load of 5 tons.
There is basically no need to refuel on such a trip, because the straight-line distance from east to west or from south to north in my country is only more than 5,000 kilometers. If it is not enough, just refuel halfway.
Moreover, this internal power generation mode also reduces the cost of the train and at the same time increases the safety. After all, the higher the dependence on the outside, the lower the safety.
At the beginning, Ye Zishu only used it as an emergency measure to avoid external accidents, and it would not affect the normal operation of the train, but in the eyes of the R\u0026D personnel, it was not only costly, but also completely unnecessary.
Moreover, aviation kerosene can be artificially synthesized by Kirin Energy Industry Group, and it cannot be said to produce additional pollution, so it can be called clean energy.
Ye Shu thought that what they said was very reasonable, so he agreed with their approach. Anyway, adding 4 tons of load, compared to building a large number of auxiliary facilities, still saves a lot of cost.
With the new plan, Ye Zishu temporarily made some revisions to the overall design with the scientific research staff. This change was not major, and it was completed quickly.
When he returned to his residence in the evening, he retrieved other information materials that matched the progress of the project to check the progress of the projects that other companies were responsible for.
Huanyu Group is not responsible for all ultra-high-speed maglev trains. Many projects are actually handed over to other companies under its umbrella. After all, many technologies are only available to other companies.
For example, conventional superconducting material technology is in the hands of Kirin Electric Industry Group, and Ye Zishu does not intend to hand over the technology to another company, and it is safer to concentrate in the hands of a group company.
For example, thermoelectric conversion materials and thermoelectric conversion power generation devices are in the hands of Kirin Energy Industry Group, and Kirin Energy Industry Group is responsible for the power generation system project.
There is also the communication system, which is handed over to Qinglong Technology Company. They have both talents and foundations in this area, and they have an obvious advantage over Huanyu Group.
There are also electrical and electronic equipment on the train, etc., which have been handed over to Xuanwu Technology Company, Qilin Electric Industry Group and Qinglong Technology Company respectively.
Even the various materials needed are handed over to Kirin Basic Industry Group. After all, Huanyu Group only masters the system integration technology of ultra-high-speed maglev trains.
This is also understandable. After all, the more complicated the systemic product is, the more difficult it is to rely on one company to complete all links, and it is unnecessary and does not have a cost advantage.
Companies like these responsible for various parts of the project have their own unique advantages in their respective fields. If they do it, the cost will be lower, the performance will be better, and it will save a lot of time and cost.
