From Almighty Scholar to Chief Scientist

Chapter 489 Astonishing Surface Material of the Moon Monument

"How do we conduct this four-degree-of-freedom experiment?"

"With four degrees of freedom, is it possible to go to the moon?"

"It might work?"

In the laboratory, everyone looked at the new device in the middle with curious eyes on their faces.

After all, this is four degrees of freedom!

In fact, in the past month, they have conducted the second ultra-long-distance experiment on the previous three-degree-of-freedom observation device. From the northern end to the southernmost end, a distance of 5500 kilometers was measured, and the final result is still very gratifying, because they succeeded.

Obviously, this is an astonishing achievement. The 5500-kilometer direct communication, compared to their previous method of placing a relay station in every other city, and then crossing dozens of cities, was able to realize the communication of several provincial capitals. too much.

This means that no matter where they are in the country, they will be able to directly transmit confidential information through quantum communication.

The most important thing is that it is still transmitted directly, without the use of quantum satellites.

The biggest problem with quantum satellites is that they are floating in the sky and cannot achieve effective defense. If a war really comes one day, then obviously, the other party can try to destroy the quantum satellites directly. In this way, the quantum communication they built before The trunk line is tantamount to wasting directly.

Of course, their Micius has actually considered this kind of thing at the beginning, so the satellite orbit where the Micius is located is a sun-synchronous orbit, which is far enough from the earth, and it is difficult to achieve an attack on the Micius. Still pretty big.

However, although it is difficult, they have to take precautions against this matter, so it is more stable to realize direct communication on the ground.

Now, they have achieved direct quantum communication across 5500 kilometers, so this problem is naturally not a problem.

Therefore, from a strategic point of view, this will completely ensure their information security, and they will no longer have to worry about information leaks and other issues.

Of course, 5500 kilometers is only the limit of their current measurement. This does not mean that they have reached the limit of the three-degree-of-freedom observation device, so they still have the opportunity to achieve longer distance measurement.

Originally, they did have this plan. They planned to cooperate with both the navy and the air force. When the time comes, let the navy go to the high seas, and then they will cross tens of thousands of kilometers on the mainland to see if they can achieve contact. The Air Force is to let the Air Force go to the sky to try to see if the Air Force's aircraft can achieve quantum communication with the ground during high-speed movement.

However, none of them expected that Lin Xiao would make this four-degree-of-freedom observation device so quickly.

The three-degree-of-freedom observation device, less than three months after its birth, has directly become an outdated technology.

Although I was very surprised that Lin Xiao had once again achieved a technological breakthrough so quickly, but there was no way to do it. Since we have done it, we can only accept it.

So now they have to start discussing how to conduct experiments.

But speaking of it, they all felt dumbfounded. They don't know how to conduct experiments now?
If there is another experiment, they will have to test it from the North Pole to the South Pole

"Maybe, now we should go to the space station for an interview?"

Someone couldn't help asking.

"It doesn't make sense." The other person shook his head and said, "After all, Mozi is in the sky."

"That's true." The person who proposed thought for a while, and finally nodded.

indeed.

The sun-synchronous orbit where Micius is located is 1400 kilometers away from the farthest point of the earth, but it is farther than their space station.

The orbit of their Tiangong space station is only more than 400 kilometers away from the earth, far less than 1400 kilometers away.

As for why Micius can achieve 1400 kilometers of quantum communication, it is actually because of quantum decoherence. On the surface of the earth, the speed of quantum decoherence is extremely high, which also caused their direct quantum communication on the surface of the earth to be greatly affected. It is not bad to have a distance of hundreds of kilometers, so the current 5500 kilometers of direct communication surprised them so much.

In the cosmic space, since it is basically empty, there is almost no environmental interference, so the influence of quantum decoherence is greatly reduced, and longer-distance communication can naturally be realized.

It is precisely because of this that they have the courage to challenge the gap between the earth and the moon as high as 40 to [-] kilometers, just to achieve a few thousand kilometers of communication on the earth.

But unfortunately, the size of the earth has become a barrier to their experiments.

After all, the diameter of the earth is only more than 1 kilometers, and they have all achieved 5500 kilometers in three degrees of freedom. Now they all have four degrees of freedom. Can't they multiply this distance by 2?

So right now, they don't know what to do.

"Lin Xiao, what are your plans?"

At this time, Pang Wei in front asked Lin Xiao.

Obviously, on this point, Lin Xiao still needs to make this decision.

At this time, Lin Xiao was also thinking about how to carry out the experiment next?
They have confirmed the feasibility of the four-degree-of-freedom observation device. After experiments, this four-degree-of-freedom observation device can transmit information, and the next step is to verify the long-distance transmission information of this device.

But now it seems that it is impossible to go to the moon.

So in the end he thought about it, and said, "Let's do it this way. Next, you try to increase the number of bits transmitted. In addition, try to see if you can achieve communication from the North Pole to the South Pole."

"Well, I see." Pang Wei nodded without any objection, after all, they can only do these two things now.

From the North Pole to the South Pole, that is, the two farthest points that can be realized on their earth.

As for the other item, increasing the number of bits transmitted is related to how much information they can transmit at one time.

After all, quantum communication is not like the current network, which can transmit a large amount of information. The size of the information that can be transmitted by quantum communication is limited by its entanglement quantum. Therefore, only by increasing the size of the information that can be transmitted can its function be improved. Otherwise, If only one bit of information can be transmitted in one second, it might as well be transmitted directly by radio waves.

This is equivalent to a person living in the country. Although he is connected to an advanced network, since the upload speed is only 1B per second, when he wants to transfer a G file to a neighboring city, it is better to directly upload the This G file is copied to the USB flash drive, and then the file is sent directly to it on horseback.

Therefore, it is also very important to increase the number of bits that can be transmitted per second.

"What about you? What are you going to do?"

And Lin Xiao smiled and said, "I have to help them and speed up the date of the next manned moon landing plan."

Pang Wei was taken aback, "Speed ​​up? How do you speed up?"

"Of course it is to help them study the spacecraft that can go to the moon."

"What, a spacecraft?"

Pang Wei's eyes widened immediately. Lin Xiao had just developed this four-degree-of-freedom quantum entanglement observation device, and then turned around to study spacecraft?
And according to Lin Xiao, it is still the kind of spacecraft that can go to the moon.

Dare he plan to start a moon landing program directly in order to test this four-degree-of-freedom observation device?
How did this give Pang Wei the feeling that he made dumplings for a plate of vinegar?
Of course, if he knew Yue Shisi, he would definitely not think so.

Because Lin Xiao obviously researched this quantum communication technology in order to go to the moon.

"Yes, the spacecraft, otherwise, the moon was so expensive last time, they must not be willing to play like this."

Of course, Lin Xiao didn't explain anything to Pang Wei, spread his hands, and then said to Pang Wei who was still surprised: "Okay, you can arrange the rest of the matter, and I should go back to Beijing."

"Of course, don't forget that our project is not completely over yet. After all, our project goal is five degrees of freedom."

Pang Wei recovered from Lin Xiao's words just now, and finally said helplessly: "Okay, I understand, you go, and leave the other things to me."

Lin Xiao smiled slightly, "Okay, that's it."

Then he turned his head to look at the other researchers in the laboratory, and said with a smile: "Thank you for your hard work during this time, let us see you at the next node before success."

The other researchers have just heard that Lin Xiao is going to study the spacecraft next time. At this time, there are all kinds of surprises and envy on their faces, and after hearing Lin Xiao's farewell words, they are also all He quickly waved his hand and said, "It's not hard work, it's all thanks to Chief Lin."

Lin Xiao smiled, and then said no more. After saying goodbye again, he left the laboratory. Next, he would hurry up and start research on aerospace aircraft.

And the others couldn't help but sigh with emotion when they saw Lin Xiao's vigorous back.

"Perhaps in this world, Chief Lin is the only one who can study quantum communication and spacecraft at the same time?"

"Sometimes it's unimaginable..."

When they were all feeling emotional, Pang Wei said: "Okay, let's start to increase the transmission size of bits according to what Chief Lin said. At least, before the next moon landing plan, we have to achieve at least one bit per second." The transmission speed of [-] bits, otherwise, when people transmit a photo back, it will not be as fast as wireless telegraphy."

"Yes!"

The researchers present responded immediately.

"In addition, contact the navy that we have cooperated with before, as well as the scientific research stations in the Arctic and Antarctic. When the time comes, we will go to the poles to do experiments together."

"By the way." Speaking of this, Pang Wei paused, and then said with a smile, "Take a trip."

The researchers present immediately cheered, and then returned to their posts one after another to start the next research work.

……

Time passes quickly.

After Lin Xiao left the Quantum Physics and Quantum Information Research Department, he packed his bags and returned to Shangjing.

Next, he will start research on aerospace aircraft, so naturally he needs relevant help.

Of course, the most critical thing is the place where the experiment is carried out.

So, he opened his mouth and asked for a huge sum of money to build the Dingguang Aerospace Research Institute.

And this huge sum of money is as high as [-] million, because Lin Xiao's aerospace research institute not only has those indoor experimental sites and instruments, but also has an outdoor experimental site.

As for his outdoor experimental site, it is an airport runway that is long enough and big enough.

The world's largest aircraft, the An-225 transport aircraft, weighs 640 tons. If it wants to take off, it needs an airport runway of 3500 meters to take off.

The Long March 4000 carrier rocket has a maximum take-off weight of more than 225 tons, which is nearly seven times that of the An-[-].

The aerospace plane, which is both an aircraft and a spacecraft, naturally cannot be smaller than the An-225 in terms of mass. Of course, it may not necessarily be larger than the rocket, because more than 80.00% or even 90.00% of the rocket is fuel.

And because the aerospace plane can take off with the help of air buoyancy like an airplane, it can replace nearly two thousand tons of rocket fuel with hundreds of tons of aircraft fuel. After all, even if it is An 225, it only needs 300 tons of fuel. up.

Of course, because of the greater weight, the take-off runway required for aerospace aircraft will be longer.

Therefore, the runway that Lin Xiao plans to build must first be very long.

According to his calculations, at least 8000 meters long would be needed. Of course, just in case, he decided to directly build a [-]-meter runway.

Ever since, he asked for so much money at once.

Of course, the higher-ups also knew that he was doing it for Yueshisi, and the aerospace plane was not only meaningful for exploring the moon, it was also very important in terms of strategic position.

After all, once aerospace aircraft are realized, it means that they will have the ability to strike from orbit, and this kind of strike has almost no solution.

Therefore, it is completely worthwhile to invest several billion yuan in the view of the above.

So in the following time, Lin Xiao began to make preparations for the Dingguang Aerospace Research Institute, including site selection, and related facilities, etc. The research institute and the runway will be built together. The estimated time required is six months.

If this time was put into the past, the time required for a [-]-meter-long airport runway is far from being completed in six months. The speed has already been greatly improved, not to mention that it is still Lin Xiao's project.

As long as the final payment is made in time, let alone six months, it will not be a problem even sooner.

In this way, the location was determined, somewhere on the outskirts of Shangjing, and then Lin Xiao waited for the construction of the aerospace research institute and the [-]-meter-long airstrip.

Of course, it is impossible for him to supervise the construction every day. It is better to leave this kind of matter to the people below, and he put his mind into the design of this aerospace plane.

Time also passed slowly.

……

until a month later.

"How should I design this thing..."

Lin Xiao lowered his head, looking at the design drawing in front of him, thinking in his heart.

The design drawing in his hand is the sketch of the space plane design that Tan Jinri asked for, and it is a structure temporarily designed by the space agency and Yueshi Division.

But obviously, this structure can't meet their requirements, because in the link of computer simulation, the fuel consumption of this structure is too high, and there is also the space engine that needs to be switched during the process of switching from aviation mode to spaceflight mode. If the time is too long, there is a 50.00% possibility of danger during the switching process.

"Too much fuel consumption?"

Lin Xiao rubbed his chin, especially during the take-off stage, which consumes a lot of aviation fuel. After all, who made the design of this structure take off as high as 2000 tons.

This problem is quite easy for him to solve.

"Xiao Mi, according to the general solution of the Navier-Stokes equation, optimize the aerodynamic design of this thing." He said.

"Good host."

Xiaomi's voice sounded from the computer, and after a while, Lin Xiao saw a brand new structure.

Looking at this new structure, Lin Xiao nodded slightly

The new structure optimized by Xiaomi based on the general solution of the Navier-Stokes equation must have basically reached a sufficiently perfect level in terms of aerodynamics.

But the final question still falls on the aerospace engine.

"It would be nice to have a material that is strong enough in terms of hardness and heat resistance."

Lin Xiao thought for a while, and then said to Xiaomi again: "Xiaomi, list all the materials on the earth that rank in the top ten in terms of hardness and heat resistance."

"Okay." Xiao Mi replied, and the next moment, Lin Xiao saw a form pop up on the computer, which was exactly the materials he wanted.

And these materials also include materials secretly researched by various countries.

However, when Lin Xiao saw the No.1 material, he was immediately shocked.

"Good guy, carbyne sulfide is only 40 times as hard as diamond, but this thing is actually 800 times as hard as diamond? What the hell is this?"

"And the heat resistance, which is actually as high as [-] degrees Celsius? No... it says more than [-] degrees Celsius, which means it hasn't been tested to the limit yet?"

Seeing this material, Lin Xiao was shocked for a while, and even wondered whether Xiaomi found the material from some unreliable science fiction novel.

It's just that when he looked ahead, he was stunned immediately, because the name of this material was introduced earlier, which is called [Moon Monument Surface Material (Powder Form)].

"The surface material of the moon tablet? Xiaomi, did you find this material from Yue Shisi?"

"Yes!" Mimi replied.

Lin Xiao suddenly realized that he had missed something.

At the beginning, the three academicians of materials science from the Yueshi Division invited him to study the materials of the moon tablet, including Liao Cheng, the director of the Yueshi Division, who also suggested that he study the materials of the moon tablet, but at that time he was obsessed with the materials of the moon tablet. The news of the Moon Monument was too shocking, coupled with the discovery of Mars by the United States, he immediately focused on landing on the moon first and then landing on fire, so he ignored this matter.

As a result, it is unexpected that the material of this moon tablet has such extraordinary properties.

So in a short while, he took out his mobile phone and was about to call one of the three academicians.

But after thinking about it, if they asked the past directly, they might wonder where they got the news from.

So he gave up this idea, and then got up, he wanted to go directly to Yueshi Division.

……

A few hours later, he came to Yueshi Division, took the elevator with a depth of 100 meters, and came to the headquarters of Yueshi Division at the bottom. He met the three academicians.

"Eh? Why is Chief Lin here? Didn't I hear that you are working on an aerospace plane recently?" Academician Yang Chaohai first saw Lin Xiao approaching, and asked in surprise.

The other two academicians also looked at Lin Xiao with the same curiosity.

Lin Xiao said with a smile: "It's not that the Institute of Aeronautics and Astronautics is still under construction, so I have nothing to do. Come and take a look. Remember that you said you wanted me to study the materials of this moon monument? Now I just come to help help."

Hearing Lin Xiao's words, the three of them immediately laughed.

"That's really good!"

"Finally I'm looking forward to you."

Lin Xiao quickly waved his hand and said, "Okay, okay, let's not talk about these things, first show me the results you have measured now."

"Okay!" Sun Chengjun nodded, then took out an experiment report from the side, handed it to Lin Xiao, and said at the same time: "I promise to surprise you."

Lin Xiao then asked "doubtfully": "Oh? How can you surprise me?"

The three academicians laughed without saying a word, and Lin Xiao also took over the experimental report, which recorded the various properties of the surface material of the moon tablet.

Even though he had been prepared for a long time, Lin Xiao still showed a shocked expression, and he didn't even need to pretend.

Because in addition to hardness and heat resistance, there are various other properties, such as tensile strength, thermal expansion coefficient, etc. Almost every property surprised him. .

And until the end, when he saw a picture, he was shocked.

Because he suddenly remembered the fusion tungsten plate!
