On the way from home to the company, Lin Dong was thinking about the technical problems about the reuse of rockets. Pen "Fun" Pavilion www.biquge.info

After more than a day, those pieces of information had already gone through Lin Dong's mind, and now these things were already technologies that Lin Dong was familiar with. Random extraction of fragments from 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 shot is already imprinted in your mind, and now it's perfectly okay to think of one of the shots casually. There's no need to pull the movie from start to finish at all.

The technology of repeated rocket launch and utilization is now also being carried out by foreigners, and the technology is already quite advanced.

The most famous of these is the American billionaire, Elon? SpaceX, a technology company created by Elon Musk. This is considered to be the representative enterprise of commercial space launch in the United States. The first stage of the Falcon 9 rocket, which they researched and manufactured, has been successfully recovered several times on land and at sea. Although this technology has not yet been officially operated on a rocket that launches satellites, it is believed that this scene will be visible in the near future.

Of course, Musk is not alone in his ambitions to engage in this technology. Jeff, founder of the American e-commerce giant Amazon? Blue Origin, founded by Bezos, is also working on this project.

Blue Origin's newest rocket, called New Green, is scheduled to be launched for the first time before 2020 and will eventually deliver commercial satellites and astronauts to low-Earth orbit, becoming another important vehicle for the U.S. commercial launch market. Blue Origin's New Shepard rocket has also been successfully launched and recovered many times, but because it flies in suborbital orbit and is less difficult than the Falcon 9, it is generally considered to be a lower level in terms of technology.

Blue Origin's new Greene rocket, named in honor of the first American pilot to fly around the Earth, John Brown? Named after Green, it is powered by seven natural gas and liquid oxygen fueled engines, with a total thrust of 1,750 tons, and is available in two versions, two stages and three stages. It is similar to the Falcon 9 in that it lowers the first stage of the rocket vertically back to the ground after being launched for reuse.

Because the Falcon 9 rocket exploded during a recent pre-launch test, the new Green now has a clear advantage.

Huaxia is at the world's first-class level in rocket launch technology, but it has not heard relevant news in terms of rocket recovery technology.

Many people, including Lin Dong, are speculating that Huaxia should have been engaged in this technology. After all, if you think about it, launching a rocket will cost at least hundreds of millions of material and financial resources, and this is just the cost. The biggest part of this is the cost of manufacturing and fuel for rockets.

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

Settle accounts, everyone knows that this is very worthwhile. However, technology 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, which is not at all lower than the technical difficulty system of the missile accurately hitting the target!

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

"Wu Qitian, manager of the commercial marketing department of Huaxia Aerospace, and Mr. Qin Xiangjie, consultant of the technical department, are now waiting for you in the reception room." As soon as he saw Lin Dong, He Dongcheng quickly introduced the situation, "At Huaxia Aerospace Group, they don't care about the matters I started to mention. Their people said that now all the people in the group are busy with the satellite launch tasks issued by the state, and there is no time to care about commercial launches. ”

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

He Dongcheng smiled bitterly: "Which ones are they that I impressed!" It was the deputy manager of the commercial marketing department who started negotiating with me, and no matter what I said, they just wouldn't let up. Even if I said that you could provide the technology for repeated rocket launches, they wouldn't want to -- that deputy manager Niu didn't 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 to discuss this matter, Manager Wu of the commercial marketing department was present, he listened to my words and was very interested, and then asked some specific things about our company, and then brought Qin Xiangjie Consultant over together."

Lin Dong asked suspiciously, "They listened to your words and believed them?" ”

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

"Later, I also asked Manager Wu. He said that first, the development history of the Changying Group and the good relationship between the military made him feel the need to understand things clearly. Second, that consultant Qin has been engaged in the research of rocket engines before he retired, and after he became a consultant after retirement, his research on rockets has become more in-depth, and he has been pondering this rocket recovery technology recently. Of course, he was mainly studying theoretically, and he didn't know how Manager Wu told Consultant Qin about it, and then they came over together. ”

Lin Dong understood a little. In this matter, I'm afraid the most important thing is still that Advisor Qin. Otherwise, a manager of the commercial marketing department will definitely not be able to care about the repeated launch of any 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 his mobile phone.

Seeing Lin Dong appear, the old man's eyes lit up, he stood up directly, and asked Lin Dong, "You are Lin Dong?" That's what you say, to be able to provide the technology for repeated launches of rockets? You're not talking nonsense, are you? ”

That's a rush enough!

Obviously, Lin Dong's words gave this old man a relatively big stimulus.

Lin Dong hadn't spoken yet, and the middle-aged man who looked very energetic had already put away his mobile phone, stood up, and came to Lin Dong first, stretched out his hand, and said with a smile: "Hello Mr. Lin." I'm Wu Qitian, the manager of the commercial marketing department of Huaxia Aerospace Group. Nice to see you! Although it is the first time we have met, in fact, we have been dealing with your Changying Group for a long time! ”

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

"That's right!" Wu Qitian said with a smile: "Our Long March series rockets, some components, use your Changying Group's flower battery, this battery is of very good quality!" ”

I see!

Before Lin Dong could speak, the old man was a little displeased when he saw Wu Qitian say good things about Changying Group, and said with a straight face: "Xiao Wu, let's focus on the repeated launch technology of the rocket this time, what is that battery?" This young man doesn't know the height of the sky, and he can't be too proud! ”

Lin Dongle is happy, this is really here to play the field! (To be continued.) )
