Chapter 768 Playing games?

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

After more than a day, the information has been passed through Lin Dong's mind, and now these things are already technologies that Lin Dong is familiar with.Extract fragments from it at will, and it will no longer cause the brain to run violently.

It's like having watched a computer from beginning to end many times, and every scene has been printed in my mind. Now it's completely okay to think of a certain scene in it.There is simply no need to pull this movie from beginning to end again.

Foreigners are also working on the technology used for repeated rocket launches, and the technology is already quite advanced.

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

Of course, it is not just the Musk family who are ambitious to engage in this technology.Blue Origin, founded by Jeff Bezos, the founder of American e-commerce giant Amazon, is also working on this project.

The latest rocket built by Blue Origin is called "New Green". This rocket technology is planned to be launched for the first time before 2020. It will eventually send commercial satellites and astronauts to low-Earth orbit and become another important player in the US commercial launch market. delivery vehicle.Blue Origin's "New Shepard" rocket has also been successfully launched and recovered many times, but because this type of rocket flies in suborbital orbits, the difficulty is lower than that of the "Falcon 9" that can perform missions, so in terms of technology On the one hand, it is generally considered to be a lower level.

Blue Origin's New Green rocket is named in honor of John Green, the first American pilot to orbit the earth. It is driven by seven engines fueled by natural gas and liquid oxygen, with a total thrust of 7 tons. , with two-level and three-level versions.It is the same as the Falcon 1750 in that the first-stage rocket is launched and landed vertically back to the ground for repeated use.

The New Green now has the advantage because a Falcon 9 rocket exploded during a recent prelaunch test.

Huaxia is world-class in rocket launch technology, but has not heard relevant news about rocket recovery technology.

Many people, including Lin Dong, are speculating that Huaxia should have been working on this technology.After all, think about it, launching a rocket costs at least hundreds of millions of material and financial resources, which is just the cost.The biggest content of this is the manufacturing cost and fuel cost of the rocket.

Do the math, if the rocket can be reused, even if only one of the first-stage rockets can be reused, it can greatly reduce the launch cost of the satellite, at least by more than half.

After all, everyone knows it's a good deal.Technology, however, is a big problem.After all, it is not easy to control such a big guy to return to the predetermined position after flying into the sky. This is not at all lower than the technical difficulty system of a missile accurately hitting the target!

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

"Wu Qitian, manager of Huaxia Aerospace's commercial marketing department, and Mr. Qin Xiangjie, consultant of the technical department, are waiting for you in the reception room." Upon seeing Lin Dong, He Dongcheng quickly introduced the situation, "At Huaxia Aerospace Group, They didn't care about the matters I mentioned at the beginning. Their people said that now all the people in the group are busy with the satellite launch mission issued by the state, and there is no time to manage commercial launches. "

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

He Dongcheng smiled wryly: "How could I impress them! It was the deputy manager of the commercial marketing department who started negotiating with me. No matter what I said at the time, they just didn't let go. Even if I said that you can provide the technology for repeated rocket launches, they And I don’t want to—the Niu deputy manager doesn’t believe that our country can have such technology. He thinks I’m fooling them!”

"Later, when I went to his office to continue discussing this matter, Manager Wu from the commercial marketing department happened to be present. He listened to me and was very interested. Then he asked some specific things about our company, and then brought Advisor Qin Xiangjie came over together."

Lin Dong asked suspiciously: "They just listened to your words and believed them?"

He was going to go over to persuade the other party, but the other party came, which obviously caught him off guard.

"Later, I also asked Manager Wu. He said that firstly, the development history of Changying Group and the good relationship with the military made him feel that it is necessary to understand the matter clearly. Secondly, that consultant Qin had been working on rocket engines before he retired. Research work, after retirement as a consultant, the research on rockets has been deepened. Recently, he has been thinking about the rocket recovery technology. Of course, he is mainly doing theoretical research. For some reason, Manager Wu told Qin about this. Counselor, and then they came together."

Lin Dong understood a little bit.This matter, I am afraid that the most important thing is that consultant Qin.Otherwise, it would definitely not work for a manager of the commercial marketing department to take care of the repeated launches of rockets!
The two 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 his mobile phone.

Seeing Lin Dong's appearance, the old man's eyes lit up, he stood up directly, and asked Lin Dong, "You are Lin Dong? You said that you can provide the technology for repeated rocket launches? Are you talking nonsense?"

That's enough!

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

Before Lin Dong could speak, the other middle-aged man who looked very energetic had already put away his mobile phone, stood up, came to Lin Dong first, stretched out his hand, and said with a smile: "Hello, Mr. Lin. I am Huaxia Wu Qitian, Manager of the Commercial Marketing Department of Aerospace Group. Nice to meet you! Although we are meeting for the first time, in fact, Huaxia Aerospace Group has been dealing with your Changying Group for a long time!"

"Dealing with each other?" Lin Dong was taken aback for a moment.

"That's right!" Wu Qitian said with a smile: "Our Long March series rockets, some parts use the flower-planting batteries of your Changying Group. The quality of these batteries is very good!"

So this is ah!

Before Lin Dong could speak, the old man was a little displeased when Wu Qitian said good things about the Changying Group, and said with a straight face: "Xiao Wu, the focus of our visit this time is on the rocket's repeated launch technology. What is that battery? This young man People don't know the heights of the sky and the earth, so we can't make him too proud!"

Lin Dong is overjoyed, this is really for fun!
