Rebirth 2008: I Can Make Money Reading

After Mu Yang left BJ, the bigwigs had an in-depth discussion on the Xinghai Group's Xingwang.

The first thing to do right now is to keep it confidential. Participants are not allowed to disclose any information to a third party. Since Mu Yang has already made preparations, he can proceed step by step.

The second thing is to do a good job in the preparations before the star network exposure;

The third thing is to support Xinghai Group’s satellite manufacturing and help solve the problem of scarce raw materials;

The fourth matter is the Xinghai Group's mobile communication license issue, whether to agree to Xinghai Group's participation in the mobile communication industry competition.

If Xinghai Group really enters the mobile communication industry, most of the state-owned enterprises will not be able to compete, and ground base stations cannot be given up. This is the cornerstone. After all, what if the Xinghai network fails one day.

In addition, there are hundreds of thousands of formal employees in the mobile communication industry, and millions of people in the industry are involved. How to arrange these employees after the failure of state-owned enterprises to compete.

Several bigwigs had a heated discussion on this issue. Those who opposed it felt that this is a livelihood industry, and Xinghai Group does not need to enter it. The state uses other resources to compensate:

There are also supporters who feel that competition can only make progress, but I hope that Xinghai Group can accept these practitioners. If good technology is not used, it will be social regression:

There is also hope that the two parties will cooperate. Xinghai Group earns patent fees through technology licensing, and the management rights are handed over to state-owned enterprises. research and development.

There is also a plan, Xinghai Group operates independently, but the price cannot be too low, and it can occupy the high-end market.

Mu Yang threw a difficult problem to the big bosses. The general direction is to recognize new technologies and support Xinghai Group to continue to develop top technologies. However, they need to make trade-offs in terms of the millions of employees in state-owned enterprises and the distribution of benefits.

As for the business problems after the establishment of Star Network, Mu Yang actually didn't think about it. If it is not used by the people of the country, it is a waste.

He returned to City H on the fifth day, April 8.

Ye Fan, the general manager of the company's space exploration technology project team, reported to him that Xingkong-1 was about to be launched to LEO, and asked him if he was free to go to the site to guide the work.

For such an important matter, Mu Yang still thought of going to see it on the spot, and also called eight of his students to see it on the spot. There are not many opportunities like this.

After Leng Han and the others knew that they could go to watch the rocket launch again, their excitement and excitement were like a flood breaking a dam.

"Sister, why don't we go to see it? Last time we went to the site to watch the rocket engine test, there was a problem. When the teacher went to see it, there was no problem. If we go to see it this time, I'm really afraid that there will be another problem. , is the bad luck we brought." Zhong Huayun was a little worried.

"What are you talking about, you crow's mouth, if something goes wrong, it must be your fault." Leng Han patted his head, but after hearing what he said, he still felt a little uneasy, he couldn't be so evil, right? .

If you don't go, I feel a little regretful, and it is the teacher who asked them to observe and study on the spot. After all, there are not many opportunities for rocket launches, and every learning opportunity is very precious.

"Senior Sister, I don't think it's nothing. How can we be superstitious when we are engaged in scientific research?"

Leng Han said solemnly: "You must go, that's all, don't talk nonsense in front of the teacher."

"Okay, I definitely understand this!"

April 9,

That night, Mu Yang and his students took their own super yacht to the rocket launch base, and the yacht arrived at the pier at one o'clock in the morning the next day, and rested on the yacht for one night.

The next morning, everyone had breakfast cooked by the chef, and at eight o'clock in the morning, they drove to the rocket launch base and the control center headquarters.

Today's launch mission is to launch the Xingkong-1 rocket into low earth orbit LEO. The planned target altitude is 500 kilometers, and then it will be recovered and required to land at a designated location.

The time from launch to orbit is about 500 seconds. If the acceleration is adjusted faster, it can be faster, but the economy is worse. If it takes 500 seconds to reach 500 kilometers, it is fast enough.

But if the speed is too slow, it cannot reach the first cosmic speed of 7.9 km/s, and it cannot enter orbit at all.

Some time ago, the scientific researchers of the project team continued to conduct experiments, and have mastered the fine-tuning technology, which can reduce the impact force to the lowest point when descending, without damaging the equipment. If there are astronauts, they can also bear it.

Seeing the chairman coming, Ye Fan walked towards him and said respectfully: "Chairman, everything is ready, please guide me."

His tone was calmer, not as nervous or excited as before.

Every time he launches a test, his temperament has to go through a sharpening, and if there is another unexpected situation, he can deal with it calmly.

Not only him, but also other colleagues in the control center.

This is the experience and psychological quality cultivated by spending money.

"Okay." Mu Yang picked up the test outline to review, and after reading it, he said relaxedly: "Boss Ye, we can implement it according to the plan.

"yes!"

Ye Fan earnestly carried out the chairman's order.

At this time, through the large screen on the control center, it can be seen that the Xingkong-1 rocket has been fixed on the launch platform, and its weight is much heavier than before.

In the fairing, 200 tons of heavy objects were loaded, including some animals, including six mice, a goat, two chickens and two ducks, which were locked in a small black room at this time, and they shouted from time to time , if you listen carefully, you can hear that the cry is a bit hoarse.

Since being locked up in a small dark room, there is no sunlight, little space for activities, and no food or water.

However, even if the scientific researchers know about their cries, they don't care. In fact, the lights can be turned on for observation, but they will not be turned on until after the rocket is launched.

The fuel weight of Xingkong-1 is poured according to the actual launch time. In this way, the real take-off weight reaches 700 tons, of which the empty weight of the rocket is 22 tons, the load to LEO is 200 tons, and the fuel reaches a terrifying 478 tons.

In fact, according to theoretical calculations, if the fuel is not used up, it can fly directly to geosynchronous orbit, and then there is still a lot of fuel left on the return trip.

However, in order to be on the safe side, more fuel is generally loaded.

In the market, the price of general-purity liquid oxygen is about 1,200 yuan, and the price of liquid hydrogen is about 2,500 yuan. The requirements for rocket launches are relatively high, but this is self-made by Xinghai Group. In fact, the price is not much different.

2H+0=2H0

Because it belongs to the full flow staged combustion cycle, oxygen and hydrogen are perfectly combusted, so the mass ratio of oxygen to hydrogen is 16:1

Of the 478 tons of fuel, the mass of oxygen is about 449 tons, and the mass of hydrogen is about 28.1 tons.

Therefore, the cost of fuel can be calculated, less than one million yuan.

Mu Yang said that the cost of a launch is 10 million yuan, which includes other expenses. If calculated comprehensively, it should not exceed 10 million yuan.

Starry Sky One

[Designed take-off thrust: 9500 kN (equivalent to 969 tons) Take-off thrust-to-weight ratio: 1.384]

Leng Han and other students came to the control center again and saw the Xingkong-1 rocket on the launch pad for the first time on the screen.

When it is ready to start, the lights in the fairing are also turned on, and every move of the animal can be seen clearly through the camera.

"This rocket looks very beautiful. I heard that there are animals in it. I don't know if I can bear it."

"The vertical upward acceleration does not exceed 3G. Without decompression suits, ordinary people can still bear it. These small animals don't know it."

"According to what the teacher said, it takes about 500 seconds to reach the preset orbit, and the average acceleration must reach more than 1.59G."

"Average is the same thing. It is also uncomfortable to be in an overload state for hundreds of seconds. Just imagine, when you are on a roller coaster, you can't bear it if you keep falling rapidly."

"Dropping and rising are two different things. The rising can withstand 3G, and the falling 1G is almost the same."

"Why is the acceleration of the descent relatively poor?"

"The blood pressure dropped to the feet, the blood supply to the head was insufficient, and fainted soon.

"I think those little animals must have a shadow in their hearts, is this something people do.

"Hehe, then I have to ask those animals, they seemed to panic for a while just now, they are so cute."

The eight students got together and chatted casually about the rocket launch.

And their teacher, Mu Yang, was chatting with Ye Fan about preparing to ignite and launch.

Near nine o'clock, engineers and technicians of various professions carried out the final inspection and operation on the rocket before take-off, and then withdrew from the site, waiting with enthusiasm for the launch time.

At about nine o'clock, Mu Yang gave Ye Fan an order: "Manager Ye, prepare to start lighting the fire."

Ye Fan heard the chairman's order, his expression was solemn, and he shouted to the test personnel: "Check the launch site!"

"Report, the inspection is complete, everything is normal."

"Check the fuel condition, air pressure..."

Following orders one after another, Ye Fan watched and inspected the results, showing that the rocket system and launch site system were all normal and good.

Reporting that everything is normal, you can proceed to the next step, and solemnly shouted: "The countdown begins."

On the screen, a countdown starts to appear.

Various tracking and measuring equipment on the site were turned on, and recording equipment such as high-speed cameras and tape recorders were started.

When "10" appeared, hundreds of scientific researchers in the control center immediately quieted down. It was another tense moment, and Leng Han and other students were more nervous and excited than them.

9!

8

-

When the "1" finished appearing, Ye Fan shouted: "Light it up!"

One order.

The operator on the launch console pressed the button calmly and decisively.

Immediately, there was a continuous and huge roar from the rocket launch site, and then, a huge white smoke came out from under the rocket.

At the same time, a huge rocket rose from the ground, rising slowly, with bright white flames spraying from its tail, pointing directly at the sky.

This time, the lifting speed was not much different from the test speed.

Ten seconds later, the camera on the launch site could no longer see the shadow of the rocket, and could only watch it through the camera on the rocket.

The screen data on the control center was constantly changing, students like Leng Han kept staring at the launch time, altitude and speed data.

Mu Yang has been standing and watching the data on the screen, occasionally watching the real-time video. As time progressed little by little, Xingkong-1 flew higher and higher.

At about 500 seconds, the reporter reported the progress: "Xingkong-1 has reached the predetermined orbit and successfully entered orbit."

At this time, the fairing has been opened.

Unlike ordinary rockets, the fairing of Starry Sky 1 slides open.

According to the test requirements, after opening and closing, go back and forth ten times, each time to check the state of opening and closing, whether it is in place.

The items in the fairing are not satellites, but experimental objects, and will not be released, and the release is space junk.

"The launch process is complete, close the fairing and prepare to land!" "Start landing!"

After this order was issued, the speed of the Xingkong-1 rocket gradually dropped to zero, and then began to fall freely.

Falling from hundreds of kilometers of space, the speed is getting faster and faster. At this time, the engine will not start, but only occasionally adjust the landing direction.

The descending acceleration is the gravity of the earth. When the speed is too fast, the engine is occasionally started to slow down the descending speed, so the descending speed is much slower than the ascending speed.

Leng Han and other students saw the teacher sitting down and waiting, and they couldn't walk around casually, so they kept staring at the data on the screen. They came to visit not only to watch, but also to learn.

When only a few kilometers above the ground, the grille is opened, the airflow is constantly swinging to adjust the attitude, and the engine is frequently fired to reduce the descent speed.

When it fell two to three hundred meters, the tail support legs of Xingkong No. 1 unfolded.

The upward thrust is getting more and more

The bigger it is, the better the weather today. When the height of the fall reaches tens of meters, the crosshairs on the designated landing site can be clearly seen through the camera video on the rocket.

However, the landing alignment is not based on video visuals, but on electronic data. 5 meters,

1 meter, 0 meters! Land, turn off the fire!

Xing Kong No. 1 stands firmly on the landing platform, and the error of the landing position does not exceed 0.3 meters.

"Wow, it worked!" Leng Han couldn't help exclaiming. "Senior Sister, it's so exciting to watch!"

"Yes, yes, our teacher is really amazing."

They are more excited than researchers, like children who have never seen the world. half an hour ago,

Several animals in the fairing animal box felt a little surprised when they saw the lights suddenly turned on.

Sure enough, the light felt better.

Suddenly, there was a roaring sound in their ears, which frightened them uncomfortably, and there was a panic, and a sudden upward force pressed them to the ground.

What happened? What are humans doing?

It's better to be quiet than when the lights are dark. Hmm, I feel dizzy and want to vomit.

I don't know how long it took, but the feeling of overload is gone.

But within a second or two, their legs suddenly left the ground a little, and then fell weightlessly.

Damn humans! What's up again? I don't know how long it took before I heard a bang, and it became quiet.

It was so quiet, there was no sound at all. The lights went out too, and it was back to before.

After the ignition test was over, these researchers just applauded to celebrate, and then quickly continued to work. It is a very complicated task to sort out the test data.

Mu Yang looked at some important test data and felt that there was no major problem, so he said hello to Ye Fan, and then took the students away from the launch base control center.

Back on the yacht by car, Jin Wei asked the teacher, "Teacher, when can we see the satellite launch?"

"I guess it will be a month or two~www.wuxiamtl.com~ but it depends on the situation." When Mu Yang said to look at the situation, he was looking at the movement of Musk's space company.

The Xinghai Group will only launch a few satellites in the early stage. After Musk's space company launches the Starlink satellites, the Xinghai Group will concentrate on making 20,000 Xingdou-1 satellites.

A few days ago, after he came back from BJ, he immediately asked Lu Ding, the production manager of the satellite project team, to count the production materials.

Just two days later, he sent the information and the contact information of the person in charge of the company to the boss's secretary.

For the rest, Mu Yang didn't need to personally urge him, and his subordinates would naturally interface. After the completion of the rocket launch LEO test,

A few days later, on April 15th,

Lu Ding, the technical manager of the satellite project team, reported to Mu Yang, saying that the Xingdou-1 satellite sample has been developed, two samples have been made, and the data is currently being tested.

"Oh, pretty fast!"

When Mu Yang received the report, he was slightly pleasantly surprised. He planned to check and accept it in two days to see how the satellite was made.
