Chapter 639: Well, let’s make one yourself

I don’t know if it’s because it’s not a system or for other reasons. The communication between the management of Baihu Technology and the space launch department about holding a symposium did not finally get a reply until December 3rd.

The symposium was scheduled to be held on the morning of December 5th, and the location was more appropriate. It was held in a certain unit in Xi'an, and Ye Zishu didn't have to travel back and forth.

Since the last meeting for the members of the military equipment expert group, he has been mainly busy with the collation of rail transit technical materials.

This is a set of systematic projects, not only track construction technology and train technology, but also communication technology and command and dispatch system, etc.

He gave thousands of material technologies alone, and each material is very critical. If you want the maglev train to reach a speed of more than 800 kilometers per hour, every detail must be perfect.

The coating on the train and the coating spraying technology are all top-notch materials and technologies, which can effectively reduce wind resistance, and even realize the reasonable use of wind, achieving twice the result with half the effort.

Also, how to maintain the stability of communication signals under high-speed operation conditions is definitely not possible to use conventional civilian communication technologies. Once the operating speed is too high, the signal stability and transmission efficiency will be much lower.

As for the dispatching system, it adopts an intelligent management model, and even the train driving has realized intelligent unmanned. As for whether people are needed or not, it depends on the meaning of the railway operation department.

In contrast, the high-speed rail in his previous life was not too challenging for him. Although many mechanical structures were used in the design, these can all be completed with the assistance of artificial intelligence. In fact, he does not need to spend too much. energy.

On the contrary, because there are not many types of new materials, it saves him a lot of time. As for the communication problem, he can directly use the same technology as the maglev train, and there is no need to repeat research.

The hybrid train is designed on the basis of the two, which is simpler. The basic technology can directly use the technology of the above two trains. The main work lies in the design, and the workload is smaller.

After Ye Zishu handed over the information to Huanyu Group, he asked them to conduct individual research in the email, to understand the research on maglev and high-speed rail technology respectively, and then to study hybrid trains.

As for the materials needed for these trains, they are handed over to the various groups under the Kirin Industrial Group to complete. This is more professional and the Huanyu Group can also reduce a lot of pressure.

In order to achieve dual-use maglev for passenger and cargo, the track is not made of ordinary materials, but a new type of material specially researched, which can realize the transport capacity of heavy-duty railways on maglev.

As mentioned earlier, if you want to reduce operating costs, you must allow enough vehicles to run on the track, and spread the cost of track construction to the number of operating trains.

If only passenger transport is available, it would be a huge waste of the expensively built rail transit, and ultimately the fare is relatively expensive.

Railways not only need to transport passenger flow, but also need to transport goods, so that the products of various cities in the inland can be transported out in time, especially for cities without water transportation facilities, which is particularly important.

Can you imagine what it feels like to pull a freight train of more than 30,000 tons and run at a speed of 800 kilometers per hour on a maglev track.

At that time, these maglev transportation networks will not only be the main artery of passenger transportation in my country, but also the high-speed engine of my country's economic development. A large number of goods will be quickly transported to all parts of the country through this transportation network.

The cost of using such a maglev train to transport goods is about twice the cost of water transport, almost no different from ordinary railway transport, but the speed is much faster.

Behind all of this is the room temperature superconducting technology. Without room temperature superconducting materials, it is impossible to run at a speed of up to 800 kilometers per hour.

If there is no room temperature superconducting material, it is impossible for the operating cost to be so low, because other superconducting materials need to spend a lot of energy to maintain the superconducting state, and there is a whole set of equipment to maintain superconducting,

The cost is not low either.

In fact, after finishing these technical materials, Ye Zishu felt that there was no need to introduce ordinary high-speed rail technology, because no matter from which point of view, ordinary high-speed rail does not have an advantage.

The only advantage may be that it can be connected with the existing railway and reuse the existing railway system, but this advantage is not obvious to him.

After he gave these technical materials to Huanyu Group, they only read the overview of these technical materials, and decided to study the maglev train technology first, because their views are the same as Ye Zishu.

When the time came to December 5th, after Ye Zishu got up and washed, he came to a place according to the address. The environment here was very good, but it was in the suburbs, which made him easy to find for a while.

It would be much more convenient if there is navigation, and he doesn’t worry about getting lost in a strange city. Although he has been here for a long time, he has basically never gone out, and he is still very strange to this city.

After arriving at the place, there was a special receptionist here. Ye Zishu followed the receptionist to the venue. In fact, there is also accommodation service here. Unfortunately, this symposium is just to understand the situation.

If it is fast, it can be done in half a day, if it is slow, one day is enough, there is no need to spend the night here, and he has no time to waste like this.

When he entered the venue, there were already about 20 people sitting here, all of whom were responsible persons from various units. Seeing so many people, he had a little understanding of the management of Baihu Technology Company.

It's not so easy to contact people from so many units. It's good for them to save face, and this is because they have heard of Ye Shu's name.

When Ye Zishu entered the venue, almost everyone looked at him, wanting to see what is so special about this young talent who has been known only by his name.

It's a pity that I really can't tell from the appearance, except that it is younger, it is not so outstanding, and it even looks better, like a cow niche.

If Mr. Tang Guoqiang were here, he would definitely say "I finally met my confidant", but he was wasted a lot of time by the impression of "cow niche".

Ye Zishu had a calm mind. He glanced at the vacant seats in the venue, saw the seat with his name, walked over to sit down, and nodded to the people around him.

He is not the host of this symposium. The host is a leader whom Ye Shu has never met anyway. He looks over 60 years old with a serious face, which is a bit different from the old man he usually sees.

After seeing Ye Zishu sat down, he directly introduced himself, and then introduced the personnel of each unit on the scene and the tasks they undertook.

These were all introduced to Ye Zishu. Ye Zishu would nod his head every time he heard an introduction, but he didn't speak enthusiastically.

After introducing the basic information, it was Ye Shu's turn to speak, and he said directly: "The main purpose of this symposium is to understand the difficulties encountered in our country's space launch work, resulting in a low launch frequency.

This is related to the next task of our Baihu Technology Company. Our satellite positioning and navigation system will be able to complete the research and development and manufacture around February next year.

The entire satellite positioning and navigation system needs to launch 55 satellites. The first phase only needs to meet the basic needs, and launching 35 satellites is enough.

In view of the needs of other businesses of Baihu Technology Company, the satellite positioning and navigation system needs to be established and operated as soon as possible, but according to the current launch frequency, it may be good to complete the launch task before the end of the year.

So I really want to know where the difficulty is. If it can be solved, then solve it and overcome the bottleneck problem. This will be very beneficial to all your units and Baihu Technology Company. "

These people are able to come here because they are all famous people. Naturally, they know what the White Tiger Technology Company he said is researching, and many scientific researchers from their units have also been seconded.

I only know the general situation, but I don't know the specific details. These are all confidential. Even the seconded personnel participating in the research cannot disclose them to the original unit at will.

"It's really difficult for you to launch so many satellites in such a short time." The moderator of the symposium said.

"Actually, this is just a satellite system. Around April next year, we will start building a remote sensing satellite system, launching a total of 66 satellites. I hope the launch will be completed by the end of the year.

So next year there will be 101 launch missions. These are relatively urgent launch missions. There will be a global satellite communication system behind, and the number of satellites will be even greater.

It’s just that in view of the actual conditions, it can be postponed until later. The earlier the two systems are established, the better. This belongs to the infrastructure of many high-tech fields and has a huge effect on national defense and people’s livelihood. "Leaf Book said.

It is unnecessary for him to say the latter sentence. The people present are all people in the industry. They are no strangers to these two systems and know how difficult these two systems are.

It stands to reason that this should be a happy event. Our country has finally made a technological breakthrough in the high-tech field, and these space launch units should actively cooperate.

"I also understand some of your affairs, but I didn't expect the progress to be so fast. No wonder you are so anxious about the rocket launch." The host leader said with a smile.

And a leader next to him said: "Since this symposium is to solve problems, we people should not be hypocritical, Mr. Ye is not an outsider, just speak out where there are bottlenecks."

As soon as these words were spoken, the people below were silent for a while, and then some people began to speak, talking about the bottlenecks they encountered in the research process they were in charge of.

With the first person to speak, the subsequent speakers became much more active, while Ye Zishu was listening and recording, and found that more and more things were recorded, which made him a little overwhelmed.

He didn't know if there were really so many problems, or if he was deliberately making things difficult for him. Anyway, the more he recorded, the more he felt that it was not very reliable, but he couldn't refute it. He couldn't just go to their unit to see it.

The whole morning passed like this, and Ye Zishu had already recorded half of the notebook. Finally, when it was time for dinner, everyone stopped talking, which made him finally heave a sigh of relief.

Seeing this situation, he felt that there was no need to continue the symposium. If there were so many problems, it would be more appropriate for him to design a new set of technology.

For him, it's easier to start from scratch than to change on the basis of others, and the whole set of technology is more advanced, tinkering has never been his habit.
