On the way from home to the company, Lin Dong was thinking about technical issues about the reuse of rockets.

After more than a day, the information has been passed in Lin Dong's mind. Now these things are already technology that Lin Dong himself is familiar with. At will, extracting fragments from them will no longer cause the brain to run violently.

It’s like watching a computer from beginning to end many times, and each shot has been imprinted in my mind. Now it’s perfect to think of one of them. There’s no need to pull the movie from beginning to end again.

Foreigners are now working on the technology of re-launched rocket launches and utilization, and the technology is already quite advanced.

The most famous of them is the Space Exploration Technology Company founded by the American billionaire Elon Musk. This is considered a representative company for commercial space launches in the United States. The first stage of the Falcon 9 rocket they researched and manufactured has been successfully recycled on land and at sea many times. Although this technology has not been officially operated on the rocket launching satellites, I believe that this scene can be seen in the near future.

Of course, it is not just Musk who is ambitious to engage in this technology. Blue Origin Company founded by Jeff Bezos, the founder of the American electronics business giant Amazon, is also carrying out this project.

The latest rocket built by Blue Origin is called "New Green". This rocket technology is scheduled to be launched for the first time before 2020. It will eventually send commercial satellites and astronauts to low-Earth orbit, becoming another important carrier for the US commercial launch market. Blue Origin's "New Shepard" rocket has also been successfully launched and recovered many times, but because this type of rocket is flying in suborbital and is less difficult than the "Falcon 9" that can perform missions, it is generally believed that it should be lower in technology.

The Blue Origin New Green rocket, named in memory of the first American pilot John Green, who flew around the earth, was driven by seven engines powered by natural gas and liquid oxygen, with a total thrust of 1,750 tons, two and three. In the same place as the Falcon 9, it landed the first-stage rocket vertically back to the ground for reuse.

Because the Falcon 9 rocket exploded during its latest pre-launch test, the New Green now has a clear advantage.

Huaxia is at a world-class level in rocket launch technology, but has not heard any relevant news in rocket recovery technology.

Many people, including Lin Dong, are speculating that China should have been working on this technology. After all, think about it, the material and financial resources consumed by launching a rocket will be at least several hundred million, which is just a cost. The biggest content of this is the manufacturing cost and fuel cost of the rocket.

After calculation, if the rocket can be reused, even if it can only reuse the first-stage rockets, it can greatly reduce the launch cost of satellites, at least by more than half.

When it comes to accounting, everyone knows that doing this is a good deal. However, technology is a big problem. After all, it is not easy to control such a big guy to fly into the sky and return to the predetermined position. This is not less difficult than the technical difficulty system of missiles hitting targets accurately!

I drove all the way to the company headquarters. As soon as I arrived at the front desk, I saw He Dongcheng was already waiting there.

"Wu Qitian, the commercial marketing department manager of Huaxia Aerospace, and Mr. Qin Xiangjie, the technical department consultant, are waiting for you in the reception room." As soon as he saw Lin Dong, He Dongcheng quickly introduced the situation. "In the Huaxia Aerospace Group, they didn't care about the matter I mentioned at all. Their people said that now all the people in the group are busy with satellite launch missions issued by the country, and they have no time to care about commercial launches."

"Then why would they come?" Lin Dong and He Dongcheng walked into the elevator and asked, "How did you impress them?"

He Dongcheng smiled bitterly: "I was not what impressed them! The person who started negotiating with me was the deputy manager of the Commercial Marketing Department. No matter what I said at that time, they just didn't let go. Even if I told you that you could provide the technology for repeated rocket launches, they wouldn't want the deputy manager Niu to not believe that our country could have such technology at all. He thought I was fooling them!"

"Later, when I went to his office to continue discussing this matter, Manager Wu from the Commercial Marketing Department was present. He was very interested after listening to me. Then he asked about the specific matters of our company, and then brought Qin Xiangjie consultant to come here."

Lin Dong asked in confusion: "They just believed you after hearing what you said?"

He was preparing to go over and convince the other party, but the other party came, which obviously caught him off guard.

"Later I asked Manager Wu. He said that, firstly, the development history of Changying Group and the good relationship between the military made him feel that it is necessary to understand things clearly. Secondly, consultant Qin had been engaged in research on rocket engines before retirement. After retirement, he became a consultant and his research on rockets became more in-depth. Recently, he has been thinking about the rocket recycling technology. Of course, he mainly studies theoretically. I don't know why Manager Wu told Consultant Qin about this, and then they came together."

Lin Dong understood a little. I'm afraid the most important thing about this matter is consultant Qin. Otherwise, a manager of a commercial marketing department would definitely not work if he had to worry about the repeated launch of a rocket!

The two of them came to the reception room together. Lin Dong saw an old man with gray hair and good spirits looking at the door, while another middle-aged man was looking at the phone.

Seeing Lin Dong appear, the old man's eyes lit up, stood up and asked Lin Dong: "Are you Lin Dong? That's what you said, can provide the technology for repeated launches of rockets? Are you talking nonsense?"

This is enough to say!

Obviously, Lin Dong's words will greatly stimulate the old man.

Before Lin Dong could speak, the other middle-aged man who looked very energetic had put away his cell phone, stood up, and came to Lin Dong first, reached out his hand, and said with a smile: "Hello, Mr. Lin. I am Wu Qitian, the commercial marketing manager of Huaxia Aerospace Group. I am very happy to see you! Although we met for the first time, in fact, our Huaxia Aerospace Group has been dealing with you Changying Group for a long time!"

"Doing?" Lin Dong was stunned for a moment.

"Yes!" Wu Qitian said with a smile: "Our Long March series rockets have some components that use the flower seeding batteries of your Changying Group. The quality of this battery is very good!"

So that's how it is!

Before Lin Dong could speak, the old man was a little displeased when he saw Wu Qitian saying good things about Changying Group. He said with a stern face: "Xiao Wu, let's focus this time on the Rocket's repeated launch technology. What's that battery? This young man doesn't know the height of the world, so he can't be too proud!"

Lin Dong was happy, this is really here to play! (To be continued.)
