Chapter 250 No, how can others play like this?

"Hahahaha, how come Guang Shen always brings out such famous scenes every time he is interviewed?"

"The host didn't react immediately. She was doing reading comprehension. I am also a human being. What kind of speech is this?"

"It seemed like the female host had fallen into a state of confusion after that question, and she was completely offline afterwards."

"Ever since the last interview when Guang Shen said he would bring everyone a golden age, I have been looking forward to what he can do this time, and the result did not disappoint me."

"To be honest, what Guang Shen said is not wrong. Among so many commercial aerospace companies, why Guang Jia Aerospace stands out? The main reason is because of his existence. This interview is so funny, mainly because Guang Shen's twist is so amazing."

"As expected, the imagination of geniuses is different from that of ordinary people. When I saw that, I thought the God of Light was going to say that our conditions were better, but he ended up saying that I am also a human being, which made me laugh to death."

"It's only interesting if Guang Shen accepts domestic interviews. If he accepts foreign interviews and answers in English, I won't get it even if he uses memes."

"There's nothing wrong with the God of Light's answer. I just want to ask if other commercial aerospace agencies can have such a God of Light?"

The joint electric-drive rocket launched by China Aerospace and Guangjia Aerospace is a hot topic in itself, and Chen Yuanguang's interview has attracted the attention of the whole of China.

A large number of viewers watched the live broadcast conducted by CCTV on Douyin.

This clip started to circulate before the talk show was over, and combined with the confused and helpless look of the female host, it created a great comedic effect.

The ghost animal up-loaders at Bilibili are happy to welcome the new material.

"How do you evaluate Guang Shen's statement in an interview that the biggest reason for the success of Light Armor Spaceflight was his existence?"

"I think there's nothing wrong with laxatives. I joined a first-tier domestic commercial aerospace company after graduating from university in 18. I can only reveal a few things about my old employer. First of all, we had raised three rounds of financing at that time, and each round was financed by a leading domestic institution with strong financial strength. At one point, Guangshen and Mr. Lin came to our founder to discuss acquisition.

What we were making at the time was a reusable rocket. These two points were enough to prove that we were doing a good job at the time and had already completed a rocket recovery.

Later, after Guangjia Aerospace launched Pioneer 1 and Pioneer 2, our market share was squeezed to the point where there was little left. It was impossible for you to compete with Guangjia Aerospace.

Because the Pioneer rocket is far ahead of us in terms of both technological maturity and cost, and many rocket launch demands come from enterprises, universities and research institutions. For them, Light Armor Aerospace has a halo.

Do you understand? It's similar to the halo of Huawei and BYD. When Pioneer 1 was launched, our launch price was comparable to that of Light Armor Aerospace, but they would not choose you, but Light Armor Aerospace.

Even if we grit our teeth and endure a certain degree of losses to maintain the market size and offer a price lower than that of Guangjia Aerospace, these companies or institutions will still choose Guangjia Aerospace.

This was an unsolvable problem, because our costs were higher than those of Guangjia Aerospace. Later, Guangjia Aerospace launched the Pioneer II, which had no market at all, and the old company went bankrupt.

I don’t deny that Guangshen is extremely strong in R&D and scientific research project management. Their halo effect in the domestic market is unsolvable.

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

Your founder has to solve the chip problem, develop technology at the same level as room-temperature superconductivity, and research technology like perovskite batteries that can increase the profit margins of the entire industry. Only when these conditions are met can you compete with Guangjia Aerospace.

Isn't this just embarrassing? If there really is such a god, I guess he must have solved the problem of controlled nuclear fusion. Then why would he 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 history of failure of our former employer after I started my own media. There is really no solution. The loss was really caused by Guangshen alone.

This is also why no one is willing to compete head-on with Light Armor Aerospace. Everyone wants to provide supporting industries for Light Armor Aerospace.

You may think the God of Light is a bit pretentious, but I think he is a bit modest. "

"Is Yuanguang so special in his normal life?" Li Xinyin looked at Lin Jia with a hint of doubt in her eyes. Chen Yuanguang's shocking remarks naturally became the topic of conversation at their gathering.

At this time, Lin Jia thought of how Chen Yuanguang usually had a serious face and rarely boasted about himself, so he shook his head and said, “No, we usually talk about work, and I think it’s a great breakthrough, many of which we pioneered, and others can’t do what Yuanguang can do, and he just explained it very calmly.

I never brag about myself, let alone say self-congratulatory words like "I am so great."

Li Xiyin thought back to when they were in college and they went to Jiangcheng to play with Lin Jia, and Chen Yuanguang also showed up. When they talked about GPA, Chen Yuanguang never said what his GPA was.

At that time they thought it was because of his poor GPA, but later they found out that Chen Yuanguang's GPA of 3.7 was enough to rank in the top five in the class, and that GPAs in basic subjects were generally low.

So Li Xinyin believed what Lin Jia said, that the Chen Yuanguang they knew before was very low-key.

"Jia Jia, do you think it is Guang Shen's nature when he accepts interviews or is it his nature at other times?" Li Xinyin asked curiously.

Lin Jia said: “I think being modest and low-key is Yuan Guang’s nature.

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

Yuan Guang doesn't care much about these things in real life.

If Lin Tianmin and others had not been arrested in America, Yuan Guang would have never thought of accepting the interview.

Precisely because I was arrested, I will not only be accepting interviews, but will also be doing a series of live broadcasts in the next few days.”

“That’s right. After becoming famous, many bigwigs like to show off in public, leaving behind many famous scenes.

Compared to them, Guangshen's words are just dry humor at best," said Li Xiyin.

The air-conditioning in Shenhai's high-end coffee shop is very strong. Only in a place like this would no one come to take a photo with Li Xiyin.

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

"Hello, are you Li Xinyin and Mr. Lin from Guangjia Aerospace?" The two typical Shenhai urban beauties, who were dressed beautifully and had exquisite makeup, recognized them.

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

After taking a group photo with them, Lin Jia and Li Xinyin looked at each other and smiled bitterly. They waited until they walked away before changing the venue.

"It seems that you are more famous. I usually come to this cafe, and even if someone recognizes me, no one comes to take a photo with me." Li Xinyin found this place, and she made up for her mistake.

Lin Jia said calmly, "It's nothing. I've been through this kind of situation a lot. When I attended a summit in Yanjing not long ago, all kinds of people I knew and didn't know came to take photos with me. This is unavoidable."

Lin Jia's thoughts were already drifting to the southwest border, wondering what Chen Yuanguang was doing. He would definitely complain about him the next time he saw him. Chen Yuanguang was preparing for tomorrow's launch with the staff of China Aerospace.

“Engineer Li, this time we will use a 1% real launch, carrying a -kilogram remote sensing satellite. After the satellite successfully enters orbit, we will allow the Shenzhou-Guangjia to return to Earth smoothly from space. The final inspection must be done by them carefully.

Although there is nothing wrong with live fireworks, I still hope to have a good start for the first time. After all, launching a rocket recovery platform is not an easy task. "

"Yuan Guang, I'm actually not too worried about the lithium batteries used in this version of the electric rocket. After all, when the Long March 270 was launched three years ago, we used -volt high-voltage lithium batteries to power the Long March .

That is not the Long March 2, to be precise it should be the Long March 130 modified. During the launch process, the battery pack has to withstand a high temperature of °C, as well as high-intensity vibration and impact in just minutes.

I believe there won't be any accidents this time. What I'm worried about is what happens after the success.

As the number of electric rocket launches and returns increases, 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, and there will always be explosions caused by lithium dendrites piercing the diaphragm.

This 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. In the short term, we will have to switch to solid-state batteries after solid-state battery technology breaks through.

Once the safety issues of small nuclear fission devices are resolved, the entire power system will have to be replaced with a nuclear fission device drive," said Chen Yuanguang.

"The risk of nuclear fission is too high. Even after rigorous demonstration, we dare not do it lightly," said Engineer Li.

Whether it is powered by electricity or fossil fuels, if it explodes, it explodes. But if it is powered by a small nuclear fission rocket and explodes in mid-air, even if it is nothing from the perspective of nuclear pollution, the sensory impact and public pressure it causes will be very great.

Therefore, there is very little application of small-scale nuclear fission in the aerospace field, let alone theoretical research.

"Dear audience friends, we are very happy to bring you the live broadcast of the launch and recovery of Shenzhou-Guangjia. This time we invited two engineers to explain it with us. They are Engineer Li from China 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 via the Long March 6 into geostationary orbit.

We will launch the Shenzhou-Guangjia rocket only after it successfully enters orbit and completes debugging.

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

Therefore, this can be regarded as a very formal rocket launch, and our Shenzhou-Guangjia electric-driven rockets will adopt a similar approach in the future.

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

After the two completed docking, the rocket recovery device sent the Shenzhou-Guangjia back to Earth.

Eventually, the Shenzhou-Guangzhou A will return to Earth according to the route we have set in advance.”

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

“Because it involves technical confidentiality, I can’t say too much.

All I can say is that traditional reusable 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 recovery, it is necessary to discard some components to change its orbit.

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

If you ignore the damage to the fuel and fairing, you can consider it a 100% recovery.

The space recovery device is like a 'person' in space. He stays in a fixed place and waits for the Shenzhou-Guangzhou A to enter the predetermined range. Then he will grab the Shenzhou-Guangzhou A and throw it back to the earth. "

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

After the satellite was deployed, its speed began to slow down, leaving it alone in the darkness of deep space.

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

The live broadcast is divided into several segments. The host and guests will only appear at key time points 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-Guangzhou Armor. When the distance is close enough, the rocket recovery device will extend its mechanical arm and take the Shenzhou-Rocket back into its arms like a human."

"It's an incredible scene. The docking of the two sides is going very smoothly. The Shenzhou-Guangjia has been successfully slowed down by the rocket recovery device."

"During this reorientation, the rocket recovery device demonstrated excellent positioning capabilities."

"At this point, it can be considered as basically successful. The rocket launcher will now complete its most important task."

“What is the most important job?”

"Give the Shenzhou-Guangjia a new coat of paint.

Everyone should know that friction generates heat. When a rocket leaves the earth and enters space, it needs to pass through the atmosphere. During the process of passing through the atmosphere, the friction between the outer shell and the atmosphere will generate a high temperature of up to 2400℃.

In this process, it is absolutely not enough to rely solely 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 temperature, the strength of the rocket shell will be greatly weakened. The high temperature will quickly spread to the inside of the rocket, burning various control instruments and electronic components. More importantly, the battery will explode directly.

We use high-temperature resistant resin combined with inorganic fillers such as silica and mica powder, as well as some sublimation substances of selenium oxide and mercury sulfide, to make thermal insulation coatings for rocket shells.

However, during the launch process, the sublimated materials of these coatings will evaporate due to the heat, and the remaining resin will form a microporous carbonized layer. We need to re-coat the rocket with a layer of thermal insulation coating in the rocket recovery device.

Let it complete this launch again and return to Earth smoothly."

The audience who were watching the live broadcast and didn’t understand thought it was nothing. Isn’t it very simple? It’s just applying a layer of film in space. Isn’t it essentially a mobile phone screen protector?

The audience who knew a little bit were all stunned. The imagination and execution were so amazing.
