January 6, 2019 at ten o'clock.

The researchers, who were in full swing, were interrupted by the sound of a microphone.

Wang Tu, the head of the Vacuum Engineering Research Institute, acted as a temporary host, and he patted the microphone:

"Bump! Touch! Please return to your seats and the meeting will begin immediately! ”

After a while, everyone took their seats, and Huang Haojie also arrived on the podium.

Huang Haojie looked around at everyone and said slowly:

"In the busy schedule to convene everyone, mainly the quality projection system engineering, has entered the practical stage, now you can click on the holographic projection on the table, the overall design scheme of the quality projection system, has been the next problem."

Everyone below hurriedly clicked on the holographic display, and a thumbnail model appeared in front of them.

"The mass projection system project will be divided into a mass projector part, a vacuum pipeline part, a ring airship part, a supercomputing center part, a storage and power station part, a bottom atmosphere monitoring part, and a projection spacecraft part." Huang Haojie continued.

As soon as he finished speaking, the logos of each part appeared in the thumbnail model in front of everyone.

Li Zhongting clicked on the vacuum pipe part, and the vacuum pipe part was immediately enlarged, and some detailed information was displayed on the side.

[Vacuum pipe part: diameter of 8 cm in cable state, diameter 96 m in vacuum excited state; The tropospheric segment (length 12 km), the stratospheric section 1 (length 12 km), the stratospheric member 2 (length 12 km), the stratospheric member 3...... Stratospheric four sections, with a total length of 60 km...... The weight of the 12-kilometer-long cable is about 48.32 tons. ］

[The cost of magnetic vacuum thin film composite carbon nanotube cable is about 40,000 Chinese yuan per meter, and the total cost of 60 kilometers is about 2.4 billion Chinese yuan.] ］

[Two superconducting high-voltage cables attached to the vacuum pipeline, with a diameter of 1.8 cm, a single line weighing about 4 tons for 12 kilometers, and two 60 kilometers weighing about 40 tons, of which the superconductor content at room temperature is 95%...... ］

Li Zhongting immediately calculated that the price of room temperature superconductors of Galaxy Technology is 50 million yuan per ton, and about 40 tons is 2 billion yuan, plus the cable must be composed of high-strength carbon nanotubes, and it is estimated that the cost of two high-voltage cables is about 3 billion yuan.

There are some other things in the vacuum pipeline, and it is estimated that the total cost of the 60-kilometer vacuum pipeline section should be about 6 billion Chinese yuan.

Of course, considering the sharing of R&D costs and construction costs, as well as profits, this price is at least about 20 billion Chinese dollars.

On the stage, Huang Haojie continued to introduce the situation of each part:

"Now in the whole system, the remaining problems are the interference of the vacuum pipe by the movement of the atmosphere, the design of the projection spacecraft, and the overload of the astronauts. These three major problems need the full support of the space agency, I wonder if there is a problem with Mr. Zhao?"

Hearing Huang Haojie's question, Zhao Hongxing nodded: "The Space Agency will definitely do its best to overcome the problem with Galaxy Technology." ”

"That's good, in addition, after the projection spacecraft enters outer space, we want to use the Beidou system and the space agency's outer space database." Huang Haojie continued.

"No problem!" Zhao Hongxing hurriedly packed the ticket.

Huang Haojie and everyone continued to discuss some things, whether it was the researchers of Galaxy Technology or the experts of the Space Agency, they all expressed their opinions and ideas.

"Mr. Huang, ask a question!" Wang Guanghai stood up and asked.

"Academician Wang, don't be polite, sit down and say."

"How to solve the outlet of the vacuum pipeline? How can the projection ship get out if it is completely sealed? If it is not sealed, air will be poured in very quickly. Wang Guanghai sat down and asked.

Huang Haojie explained: "This problem, I have also thought of several solutions, the first is to seal the warehouse door, and wait for the projection spacecraft to reach when the warehouse door is about to open, of course, this method is not perfect, the strong atmospheric pressure may instantly crush the warehouse door, if the warehouse door is too thick, you have to consider the load problem of the ring airship." ”

Wang Guanghai nodded: "The warehouse door plan is not very practical, even if the warehouse door can withstand atmospheric pressure, the grasp of time is definitely a problem, and the ship may be destroyed and killed in a second." ”

"The second option, a disposable magnetic vacuum film, is covered with a magnetic vacuum film on the exit at 60 kilometers, and this magnetic vacuum film needs to weaken the frontal stress, like a balloon that bursts with a puncture, so that the projection spacecraft can penetrate the film on its own."

When everyone present heard this plan, they began to discuss it one after another.

Disposable films? Wang Guanghai bit the pen and thought about it.

"There's no problem with this!" Li Xiang of the Materials Research Institute stood up and said:

"Because the side of the film facing the atmosphere is under tremendous pressure when it is excited in a vacuum, the entire film structure collapses due to a chain reaction when pricked with a sharp needle."

Everyone listened to Li Xiang's explanation, and after thinking about it, they nodded in agreement.

"If that's the case, wouldn't it be very dangerous if a bird or something hit the vacuum pipe?" Wang Guanghai asked another question.

Huang Haojie explained with a smile:

"It's a possibility! But don't worry too much, the first vacuum pipe is in the excited state, those currents will make the birds feel frightened, and the potential energy of the second bird in flight is not enough to break through the vacuum pipe, after all, the two sides are not in relative motion. ”

Wang Guanghai nodded: "I suggest adding some sonic equipment to expel birds, after all, at the moment when the vacuum tube is excited, if there are birds flying over, it is possible to form a relative movement, and it is better to take precautions." ”

"Academician Wang has a point, then install some sonic equipment near the vacuum pipe on the bottom floor to expel birds." Huang Haojie adopted this opinion.

Li Zhongting also stood up and said:

"I looked at the vacuum pipe in the cable state, the diameter is 8 centimeters, in this state, the atmospheric interference factors can be ignored; But in the excited state, with a diameter height of 96 meters, we want to come up with a more reasonable plan, otherwise we will be in big trouble. ”

"Choosing the right weather can reduce some disruption." Wang Guanghai proposed.

Huang Haojie shook his head: "This plan doesn't work, in our plan, the quality projection system will run for a long time, and it can't be like getting married and watching the days!" ”

"Haha......" everyone burst out laughing.

The solemn atmosphere was diluted by laughter, and after a while, the discussion continued.

"Boss, it's better to add more or increase the weight of the airship at an altitude of 12 kilometers in the troposphere, after all, the area with the most serious interference with atmospheric movement is the troposphere." Wang Tu, head of the Vacuum Engineering Research Institute, proposed.

Huang Haojie thought for a while: "This can be considered, increasing the number of ring-type airships should be able to play the effect of wind dampers, but the specific number of ring-shaped airships that need to be added is up for discussion." ”

"Our space agency's aerodynamics research institute may be able to help!" Zhao Hongxing interjected.

Since the space agency is willing to take charge of this issue, Huang Haojie couldn't ask for it, and immediately agreed:

"Then this problem will be jointly tackled by the Aerodynamics Research Institute of the Space Administration and the Atmospheric Motion Research Institute of Galaxy Technology."

"We'll arrange this as soon as we get back." Zhao Hongxing said as he took notes.

The problems were brought out and discussed, and with the collective wisdom of the people, many problems had solutions.

Although I don't know if the plan will work, it is better to have a direction than to run around like a headless fly.
