Rebirth 2008: I Can Make Money Reading

To be honest, Mu Yang couldn't help laughing when he saw Musk's reply to the media interview that "preemption is king".

Musk's character is like this, sometimes he is very nervous, and he may even dance to celebrate.

In his previous life, Mu Yang saw a video of this guy dancing so terribly, he really wanted to kick him.

But to be honest, people have that strength, it is hard power, and they have to obey.

His secretary, Chen Jiajia, saw the chairman laughing, thought he was angry, and said: "Chairman, this Musk is too arrogant, and many netizens condemn him on the Internet. However, the chairman, you are a big shot, no You need to be angry with this kind of person.”

"Don't be angry, I'm very happy." After hearing this, Mu Yang replied with a smile.

"oh."

After Chen Jiajia finished speaking, she put down the document and left the chairman's office. In fact, she didn't quite believe it. The chairman must be angry.

However, she can't control this kind of thing, she's just a secretary.

In fact, she didn't know the status of the company's rocket research projects.

…

On the Internet, a number of media have analyzed and reported on the Falcon 9 developed by Musk’s spacex company, one of which wrote:

[The height of Falcon 9 is 68.4 meters, the diameter is 3.7 meters, and the mass after full fuel is 505 tons. The payload to leo is 13.1 tons, and the payload to gto is 4.85 tons.

It is a two-stage rocket, the thrust of the first stage is more than 510 tons, and the thrust of the second stage is 45 tons.

The Xinghai Group’s rocket has not yet been announced, but judging from the photos taken secretly, there is not much difference in the size of the two rockets.

Judging from Xinghai Group's past tone, the thrust of the developed rocket will not be too bad.

However, according to relevant inside information, SpaceX has initially mastered the recycling technology, so it announced the Starlink plan.

In the past few days, the Xinghai Group has not made any movement, it should be undergoing a large-scale assembly to prepare for trial ignition...]

[According to Mu Yang's past temperament, such an announcement by SpaceX should be a big news within a few days, but this time it didn't, which makes people puzzled. It seems that Xinghai Group's rocket project is not progressing smoothly, after all, it has not been established for a long time. 】

The analysis of this media is well-founded. The Xinghai Group is indeed undergoing large-scale assembly. The assembly has been completed and is ready to be moved to the launch site.

March 1.

The Xingkong-1 rocket of the Xinghai Group moved to the launch pad at the launch site and began to replenish fuel.

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

The next morning, Mu Yang ate the chef's breakfast. At eight o'clock in the morning, he drove to the rocket launch base and the control center headquarters.

Ye Fan is the project technical manager of the rocket engine and the general manager of the space exploration technology project team.

After seeing Ye Fan, Mu Yang asked him about the preparations for the scene.

Ye Fan took a few pages of documents and handed them to Mu Yang: "Chairman, this is the pilot ignition test process."

"Um."

Mu Yang took over the test process materials, also known as the test outline, which listed what to do in the first step, who is in charge, progress and time points.

The specific procedures or steps of each step will not be described in detail in this document.

This kind of information was made by the project team. Mu Yang didn't intervene in these details, but just took a rough look.

He asked that the experiment must be prepared with the outline of the experiment, but it doesn't matter if you know it in your head.

When experimenting, even if you are familiar with the process, it is easy to miss it.

Today's ignition test was only launched to a height of 1,000 meters, then fine-tuned for ten seconds at this height of 1,000±20 meters, and finally recovered, and required to land at a designated location.

The height of 1,000 meters is not high, and it takes about 25 seconds to rise from lift to 1,000 meters.

It can't be too low, or it may hit the launch tower when landing.

If the vertical height range is too large and the fluctuation speed is too fast during fine-tuning as the fuel decreases, then the descent speed will not be well controlled during landing, the force of impacting the ground will be too large, and the recovery may fail. During the manned test , Astronauts can't bear too much impact.

In order to ensure the control of the impact force during recovery, they need to constantly conduct experiments and master fine-tuning techniques.

Because it is a test, the fuel is not full, so as not to explode in case of an accident, just add more than 100 tons of fuel, which is enough for the test.

Before that, they had conducted countless tests on the rocket engine, and they had mastered the fine-tuning of the thrust, but they did not conduct large-scale assembly tests with the main body of the rocket, and the difficulty was completely different.

Thrust fine-tuning can only be controlled through the system, and the most feared signal delay.

After understanding the situation, Mu Yang asked Ye Fan solemnly:

"Manager Ye, how are you getting ready?"

"Chairman, everything is ready, waiting for the ignition test." Ye Fan replied respectfully, "It was drizzling this morning, and the sky was covered with dark clouds, which may have some impact."

His tone is one part excited, nine parts nervous, and the pressure is very high. More than a year of hard work depends on today.

The last ignition test of the rocket engine Xinghuo-1 failed, which made him very embarrassed.

After the chairman left, they re-tested many times after a while, and the test results showed no problems, which was considered a success, but the chairman was not on site.

If the Xingkong-1 ignition test fails this time, then he is really unlucky, there is no mouse hole for him to get into.

Unfortunately, the weather today is not very good, and it hits the misty and rainy season in March, but the chairman told him in the morning that if we can't launch without ignoring the weather, we will fail to achieve our goal.

Moreover, the weather is raining and the sky is cloudy. If there are satellites in the sky, the observation is not very clear, which is exactly what he wants.

Well, Ye Fan was very helpless, he was a little worried about choosing to launch at this time.

The sky was gray and it was raining, which was a sign of something bad no matter what.

He is not superstitious, but he is really a little uneasy at this moment.

Not to mention him, the same goes for other colleagues in the control center.

"According to the plan, wouldn't it be better to drizzle." Mu Yang said lightly.

"OK!"

Ye Fan had no choice but to carry 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 instead of on the test stand.

【Star One

Overall length: 45.860 meters

Wingspan: 5.50m

Cylinder diameter 3.7 meters...]

Seen from a distance, it is a towering Optimus Prime, painted silver and white, with four large characters "Xingkong No. 1" and the logo "xh" of Xinghai Group. Painted in bright bright red flag.

Four big characters, it tells people all over the world that this belongs to a company's launch rocket.

It belongs to the glory of Xinghai Group!

Mu Yang was also very moved when he saw these four big characters, which belonged to his sea of ​​stars.

So, he came for the first ignition test, and he wanted to witness the moment when Xinghai Group took off.

The engineering and technical personnel 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, after Mu Yang knew that the preparations on the scene were about the same, he issued an order:

"Manager Ye, get ready to light the fire."

When Ye Fan heard the chairman's order, his expression was solemn, and he shouted to the experimenters:

"Check the launch site!"

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

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

…

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 researchers in the control center clenched their fists.

9!

8

…

One by one, mechanical readings echoed in the control center, and everyone's faces were very solemn.

1

After shouting "1", 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. The sound was like a landslide, a tsunami erupting, shaking the earth.

Then, 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.

In the first second of lifting, the acceleration is not fast.

The acceleration of the rocket lift is not uniform. In the second second, the take-off height is about ten meters.

In the fifth second, the height of the bottom of the rocket exceeds the launch tower.

The thrust of Xingkong-1 is extremely high, but the ignition and launch are not at full power. Otherwise, the vertical height of 100 meters will be reached within five seconds of take-off.

With each second of time advancing, the rocket lifts faster and faster.

By the tenth second, the altitude had exceeded two hundred meters.

At this time, the vertically rising rocket began to turn, and the exhausted gas condensed into smoke in the air, like a white dragon soaring upwards.

In the vast sky, coupled with the hazy weather, the rocket gradually became a small bright spot.

The modern measurement and communication equipment developed by Xinghai Group tightly "bites" small bright spots invisible to human eyes, and very accurately detects, tracks, records and reports the rocket's flight speed, altitude and attitude at every moment.

Every second, a large amount of measurement data is collected from all directions to the measurement and control center, and the information measured by each station and the flight status of the rocket are transmitted to the measurement and control center and command center in the launch site area in time.

Although it is not very clear to the naked eye, the display instrument shows data such as the height, speed, acceleration, thrust, and weight of Xingkong-1.

At about 22 seconds, the rocket reached a height of more than 900 meters.

Suddenly, the tail turned off!

But it didn't completely extinguish the flame, and the few small nozzles outside the middle nozzle still spew out flames from time to time, so its acceleration is not equal to gravity.

This is not a glitch.

The speed of the rocket is very fast, but after the flame is turned off, there is still an upward inertia.

"965 meters, acceleration minus 8.3m/s2"

"978 meters, acceleration minus 8.5m/s2"

"998 meters, the acceleration is minus 9.8m/s2, and the speed is 0!"

At this time, Xingkong-1 just reached the speed of 0 and was at the highest point. The engine was completely turned off and there was no thrust, and its acceleration was equal to gravity.

When it was about to fall, the engine ignited again instantly, and the acceleration was controlled to 0.

However, fine-tuning the posture is not so easy to adjust.

Through the feedback video shot by the camera installed on the rocket, it can be seen that, except for the flames spewing out from the nozzles at the tail of the rocket, there are strong airflows spewing out from time to time around it, as well as the upper part.

Unlike Falcon 9, which uses nitrogen to control its attitude, Xingkong-1 is completely controlled by Xinghuo-1 engine.

997 meters,

999 meters,

998 meters,

…

The Xingkong-1 rocket seems to be fixed in the sky, it can only float up and down, and it still shakes a little, but the fairing can still maintain the upper part.

The fuel is continuously decreasing, and the thrust is constantly changing. Everyone knows that the rocket is successful when they see the data of the rocket's up and down fluctuations.

After about ten seconds,

"Start landing, adjust the attitude, and descend to the designated place!"

Ye Fan shouted excitedly.

Xing Kong No. 1 suddenly shut down, and the rocket fell freely, 995 meters, 975 meters...

When it was about 500 meters away, all the nozzles at the bottom of the tail sprayed out flames. Because it was in a falling posture, the flames did not form jets, but were rushed into a big trumpet shape by the airflow, and the flames covered half of the rocket.

The sound "huhu" exploded.

Except for the flames spewing out, the descending speed is getting slower and slower.

455 meters,

415 meters,

…

At the same time, the grille that has already been deployed on the rocket constantly swings the airflow to adjust its attitude.

When it fell to tens of meters, the tail support legs of Xing Kong No. 1 unfolded.

The ascent thrust is getting stronger and stronger, and when the falling height reaches 20 meters, the rocket is already clearly seen above the cross mark at the designated position through the camera video on the rocket.

15 meters,

14 meters,

…

1 meter,

0.6 meters,

0.3 meters,

0.15 meters,

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 0.5 meters.

"Woohoo, it worked!"

"Yeah, sprinkle flowers on the ground!"

The researchers in the control center couldn't help but stood up and cheered, their moods tumbling like ocean waves.

How many days and nights, countless scientific research pioneers fighting at the rocket base, how hard work they have paid for the development and launch of rockets!

The fairing of Xing Kong No. 1, the bright red flag is still standing!

I was so excited that many researchers couldn't help but burst into tears.

Everyone was overjoyed and hugged each other to celebrate.

"Yes, it was successful once!"

Mu Yang applauded first, and the others followed suit. The applause was thunderous.

Ye Fan was very excited when he heard the chairman's approval, and he was really afraid that he would lose face again today.

However, Ye Fan knew it was not over yet, so he asked the testing data personnel: "How about the impact of the drop?"

"The instantaneous acceleration of the support frame is 0.12m/s2, the final velocity is 150mm per second, the impact force is 102.2kn, and the overall remaining weight is 102.3 tons."

"Okay, check the data, check the damage to the various parts of the rocket."

Ye Fan nodded. The support frame is equipped with a buffer device, which can reduce the speed to 0. If the speed is too fast, the support frame will be damaged by impact, and the rocket body will rebound and jump up. If it cannot be reached, it will fall down.

When Mu Yang heard this data, it was considered a very good result. He was also excited, but he still needs to practice more, and then try to fly to Leo.

"Very good, within the scope of the test requirements, after the inspection, you can relax for a few days. Next, you need to practice a lot, and after you master it more proficiently, you can go to the next step to launch to Leo." Mu Yang explained seriously.

After the ignition test, they have to wait for the specific experimental data to be sorted out. Whether the rocket can be reused and how many times it can be used is very important.

Of course, the result Mu Yang most wanted to see had already been seen: a perfect success.

The most critical step has been successful, even if the others are not done well, the difficulty of improving is not as difficult as recovering technology.

This success ~www.readwn.com~ stems from the fact that the scientific researchers of the project team have conducted many engine tests and accumulated a lot of experience, which is not achieved overnight or by luck.

After watching the experiment, Mu Yang left the scene. That night, he returned home.

"Did the rocket test succeed?" Song Xuelu asked curiously when she saw her husband come back. Seeing the relaxed expression on his face, she smiled, "It must have been successful, right?"

He told her that he went to the rocket base to inspect the ignition test.

Mu Yang nodded gently and smiled: "Well, the test went well, but there are still two big steps to go. After they are proficient in the test, the next step is to launch the rocket into a close orbit. If it is successful, the last step is to assemble the satellite and actually launch it." satellites.

It is not a simple matter to launch a satellite into a specific orbit.

Some countries launched satellites, and they obviously launched into space, but the satellites eventually deviated from orbit and eventually failed. "

"Oh, that's it. But you have to eat the food one bite at a time. If you don't have to hurry, you will become fat if you eat one bite at a time."

"That's the truth, but time doesn't wait." Mu Yang said, after Musk's SpaceX company launches the Starlink satellite, theirs will also be launched.

"Honey, don't put too much pressure on yourself, just do your best." Song Xuelu comforted.

"Don't worry, the most difficult step has been succeeded. After a year, the pressure will be on other people's side."
