Chapter 250 No, how can others play like you?


Chapter 250 No, how can others play like you?

"Hahahaha, how come Guangshen brings such a famous scene every time he is interviewed?"

"The host didn't react at the first time, she was doing reading comprehension , I am also a human being. What kind of speech is this?”

“The female host felt that she had fallen into a state of confusion after that question, and she was offline the whole time.”

“Since the last time. After Guangshen said during the interview that he would bring a golden age to everyone, I was looking forward to something good this time, and I was not disappointed.”

"Honestly, Guangshen is right. There are so many commercial aerospace companies. Why Guangjia Aerospace stands out? The main reason why Guangjia Aerospace stands out is because of his existence. This interview is so funny, mainly because Guangshen's twist is so amazing."

"Sure enough, the brains of geniuses are different from those of ordinary people. When I saw that, I thought God of Light was going to say it was because our conditions are better, but he said, "I am a human being too," which made me laugh to death. "

"Guangshen still has to accept domestic interviews to be interesting. If he accepts foreign interviews and answers in English, I can't get it even if he makes jokes."

"There is nothing wrong with Guangshen's answer. I just asked if other commercial aerospace agencies can have such a light god?”

The joint electric-driven rocket between China Aerospace and Guangjia Aerospace is a hot event, and Chen Yuanguang’s interview has attracted the attention of the entire country.

A large number of viewers watched Yangma’s live broadcast on Douyin.

Before the talk show ended, this clip began to circulate. Combined with the helpless eyes of the female host, the comedy effect was full.

The ghost up owners of Station B are happy to welcome new materials.

“How do you evaluate Guangshen’s statement in an interview that the biggest reason for the success of Guangjia Spaceflight is his existence?”

“Laxative, I think there is nothing wrong with it. I have been since 18 years old. After graduating from college, I joined a domestic commercial aerospace company. I can only reveal a few points about my old employer. First of all, we had raised three rounds of financing at that time, and each round was financed by leading domestic institutions with strong capabilities. , at one point Guangshen and Mr. Lin came to our founder to discuss acquisitions

What we were doing was a recyclable rocket. These two points were enough to prove that we were doing pretty well and had already completed one rocket recovery.

Later, with the launch of Trailblazer 1 and Trailblazer 2 by Guangjia Aerospace, our market was squeezed to the last bit. It is impossible for you to compete with Guangjia Aerospace.

Because the Trailblazer rocket is far ahead of us in terms of technological maturity and cost, combined with the fact that many rocket launch demands come from enterprises, universities and scientific research institutions, for them, Light Armor Aerospace has Aura.

Do you understand? Similar to Huawei BYD's halo. When Trailblazer 1 was launched, our launch quotation could be the same as that of Light Armor Aerospace, but they would not choose you, they would still choose Light Armor Aerospace.

Even if we bite the bullet and endure a certain degree of loss, we still have to maintain the market size and make the quotation lower than that of Guangjia Aerospace. These companies and institutions will still choose Guangjia Aerospace.

This is an unsolvable problem, because our cost at that time was higher than that of Light Armor Aerospace. Later, Guangjia Aerospace launched the Trailblazer 2, but there was no market at all, and the old employer went bankrupt.

Guangshen is super strong in R&D and scientific research project management. I don’t deny this. Their halo effect in the domestic market is even more unexplainable.

If a new company were to emerge today and be as good as or even better than Guangya Aerospace in recyclable rocket technology, you would not be able to compete with Guangzhou Aerospace.

Your founder has to solve the chip problem, develop technology of the same level as normal temperature superconducting, and research technologies like perovskite batteries that can increase the profitability of the entire industry. Under these conditions, you Only then can we compete with Guangjia Aerospace.

Isn’t this simply embarrassing people? If there really is such a god, I guess we have to solve the problem of controllable nuclear fusion. Then why do people want to engage in commercial aerospace and compete with the God of Light?

What Guangshen said is very simple. As a former competitor of Guangjia Aerospace, I later reviewed the entire failure history of our old club after doing self-media. There is really no solution. We really lost to Guangshen. On one person.

This is why no one wants to compete head-on with Guangjia Aerospace. Everyone wants to build supporting industries for Guangjia Aerospace.

You may think Guangshen is a bit pretentious, but I think he is a bit humble. "

"Is Yuan Guang so special in normal times? "Li Xiyin looked at Lin Jia with a trace of doubt in her eyes. Chen Yuanguang's amazing speech naturally became the talk of their party.

At this time, Lin Jia thought that Chen Yuanguang usually had a serious face and rarely boasted. He shook his head and said: "No, we usually talk about work. I think there are great breakthroughs. We are the first to do many things that others can't do. Yuan Guang can do it. He just explained the matter very plainly.

I would never brag about myself, let alone brag about myself like "I'm awesome." ”

Li Xiyin thought of when they were in college before, they went to Jiangcheng to visit Lin Jia, and Chen Yuanguang also showed up. When they talked about grade points, Chen Yuanguang never said what his grade points were.
< br>At that time, they thought it was because of his poor grades, but later they learned that Chen Yuanguang’s grade point of 3.7 was enough to rank among the top five in the class, and his grade points in basic subjects were generally low.

So Li Xiyin believed what Lin Jia said. The Chen Yuanguang they met before was very low-key.

"Jiajia, do you think it is Guangshen's nature to accept interviews or his usual nature? "Li Xiyin asked curiously.

Lin Jia said: "I think being humble and low-key is Yuan Guang's nature.

Because if he really likes to be high-profile and likes to be praised by others, then he should open a self-media and post on Weibo frequently. No matter what content he posts, there will be a lot of netizens praising him below.

In reality, Yuan Guang doesn't care much about this.

If Lin Tianmin and others weren't arrested in Amerikan, Yuan Guang wouldn't care about it. I had no idea of ​​accepting an interview before.

Because I was arrested, I will not only accept interviews, but also have a series of live broadcasts in the past few days.”

"Yes, after becoming famous, many big guys like to attend various public occasions to show off, leaving many famous scenes.

Compared with them, Guangshen's humor is cold at best." Li Xiyin said.

Shen Hai's high-end cafe is fully air-conditioned, and only in this kind of place, no one will come to take photos with Li Xiyin.

As a well-known YouTuber, it is normal to meet fans.

"Hello, are you Li Xiyin and Mr. Lin from Guangjia Aerospace?" The two typical Shenhai urban beauties with beautiful clothes and exquisite makeup still recognized them.

"Can I take a photo with you two? Mr. Lin, I have always admired strong women like you. Xiyin, I often watch your show."

After taking a photo with them, Lin Jia and Li Xiyin looked at each other and smiled bitterly, and then changed the venue after they walked away.

"It seems that you are more famous. I usually come to this cafe, and even if someone recognizes me, no one comes to take pictures with me." Li Xiyin found the place, and she created it for herself Make up for mistakes.

Lin Jia said calmly: "It's nothing. I have experienced many such occasions. When I attended the summit in Yanjing not long ago, various people I didn't know came to take photos with me. This is inevitable."

At this time, Lin Jia's thoughts had drifted to the southwest border, wondering what Chen Yuanguang was doing, and he must complain about him next time he saw him. Chen Yuanguang is currently preparing for tomorrow's launch with the staff of Huaguo Aerospace.

"Gong Li, this time we will adopt a 100% real launch, carrying a kilogram-level remote sensing satellite. After the satellite is successfully put into orbit, the Shenzhou-Guangjia can be successfully launched from space. Back on Earth, they must do the final inspection carefully.

Although it is okay to play fireworks live, I still hope to have a good start the first time. After all, launching a rocket recovery platform is not the same. What an easy thing.”

“Yuan Guang, actually I’m not too worried about the lithium battery used in this version of the electric rocket. After all, when the Long March 6 was launched three years ago, we used 270 volt high voltage. The lithium battery is used to provide power for the Long March 6.

That is not the Long March 6, to be precise, it should be the Long March 6 modification. During the launch process, the battery pack has to withstand 130 times in just 2 minutes. ℃ high temperature, plus high intensity vibration and impact.

I believe there will be no accidents this time. What I am worried about is what will happen after success.

As electric-driven rockets launch and return more and more times, the problem of lithium dendrites caused by the charging and discharging of lithium batteries has not been solved. In addition, it is used in extreme scenarios such as rocket launch and recovery. There will be an explosion caused by lithium dendrites piercing the diaphragm.

This issue is actually something we will focus on later. We need to find a balance between cost and safety. ”

“I think lithium batteries are only a temporary solution. We will still have to replace solid-state batteries after a breakthrough in solid-state battery technology in the short term.

After the safety issues of small nuclear fission devices are solved, the entire power system must be replaced by nuclear fission device drives. "Chen Yuanguang said.

"The risk of nuclear fission is too high. Even after rigorous demonstration, we would not dare to do it easily." Li Gong said.

Whether it is electric drive or fossil fuel drive, if it explodes, it will explode. If it uses a small nuclear fission drive and explodes in mid-air, even if it is nothing from the perspective of nuclear pollution, it will cause a sensory impact. There is also great pressure from public opinion.

Therefore, there are very few theoretical studies on small-scale nuclear fission, let alone applications in the aerospace field.

“Dear audience friends, I am very happy to bring you the full live broadcast of the launch and recovery of Shenzhou-Guangjia. This time we have invited two engineers to interpret it with us. The two engineers are from China. Engineer Li from Guangjia Aerospace and Engineer Yang from Guangjia Aerospace. Please give us a brief introduction to this launch mission. ”

"This time we will first launch a rocket recovery device into space through the Long March 6 into geostationary orbit.

After it is successfully put into orbit and debugged, we will launch the Shenzhou-Guangjia rocket.

This time, the Shenzhou-Guangjia will carry a high-orbit optical remote sensing satellite.

So this time can be regarded as a very formal rocket launch. In the future, our Shenzhou-Guangjia will be launched. Electrically driven rockets will adopt a similar approach.

After the Shenzhou-Guangjia successfully delivers the remote sensing satellite into orbit, it will wait for our rocket recovery device to pick it up.

After the two complete the docking, the rocket recovery device will send the Shenzhou-Guangjia back to the earth.

In the end, the Shenzhou-Guangjia will return to Earth according to our pre-set route. "

"What sounds very different is the rocket recovery device. How is it different from traditional recyclable rockets? "The host asked curiously.

"Because it involves technical secrets, I can't say too much.

All I can say is that traditional recyclable rockets need to be separated, and some unnecessary parts will be discarded. Even if this part is actually valuable, in order to ensure the smooth completion of recycling, So it needs to lose some components to change its trajectory.

And we use a space recovery device to achieve complete recovery of the rocket.

If you don’t consider the damage to the fuel and fairing, you can regard it as 100% recycling.

The space recovery device is like a 'person' in space. He stays in a fixed place and waits for the Shenzhou-Guangjia to enter the predetermined range. It will catch the Shenzhou-Guangjia. Then thrown back to Earth. ”

Two and a half minutes after launch, at an altitude of about 80 kilometers, Shenzhou-Guangjia entered the second stage from the first stage and began to enter orbit to deploy satellites.

Satellite deployment completed After that, its speed began to slow down, and it was alone in the dark sky

For a long time, the entire live broadcast was black.

The live broadcast is divided into several sessions. The host and guests will only appear at key moments to provide commentary. Most of the time, there is only one live broadcast screen left for netizens to enjoy themselves.

“We can see that the rocket recovery device has appeared behind the Shenzhou-Guangjia. When the distance is close to a certain extent, the rocket recovery device will extend its mechanical arm and lift the Shenzhou-rocket like a human. "It's an incredible picture. The docking between the two parties is very smooth, and the Shenzhou-Guangjia was successfully slowed down by the rocket recovery device."

"In this reorientation, the rocket recovery device showed excellent positioning capabilities."

"At present, it can be regarded as basically successful. The rocket launcher will complete its most important work."

"What is the most important work?"

"To Shenzhou -The Guangjia is repainted.

Everyone must know that friction generates heat when the rocket leaves the earth and enters space. During the process of passing through the atmosphere, the outer shell and the atmosphere are separated. Friction will generate high temperatures of up to 2400°C.

In this process, it is absolutely not enough to rely on materials such as titanium alloy, beryllium alloy, and aluminum alloy in the rocket shell, because these materials conduct heat very quickly.

If the rocket shell is directly exposed to high temperatures, the strength of the rocket shell will be greatly weakened. The high temperature will quickly spread to the interior of the rocket, burning out various control instruments and electronic components. More importantly, the battery will directly explode.

We use high-temperature resistant resin combined with inorganic fillers such as silica and mica powder, as well as some sublimated substances of selenium oxide and mercury sulfide, to make the heat-insulating coating for the rocket shell.

However, during the launch process of these coatings, the sublimated substances will be volatilized by heat, and the remaining resin will form a microporous carbonized layer. We need to re-coat the rocket in the rocket recovery device. Insulating coating.

Let it be completed again so that the launch returns to Earth smoothly. ”

The viewers who are watching the live broadcast think it’s okay if they don’t understand. Isn’t it very simple? It’s just to apply a film in space. Isn’t it essentially a mobile phone film?

Audiences who knew a little bit about it were shocked, the imagination and execution were so awesome.
