Chapter 12 Heavy Recoverable Launch Vehicle

Du Xingyu's words naturally aroused heated discussions on the Internet, with both approval and slander, but at this time he no longer cared.

At the Rocket Research Center, the research team is having a meeting. This is also the first time Du Xingyu has attended a meeting of the research team.

"Du Xingyu, everyone must know him, right?" Liu Yuan asked Du Xingyu to introduce himself. Everyone nodded and looked at the young rocket engineer curiously.

"Okay, let me talk about our mission schedule for the past two months. In two months, our 'Tianwen-1' Mars probe will be launched. Every two years and two months, Mars and the Earth will Run to the nearest distance." He Jingcheng, the team leader and chief engineer of rocket research and development, spoke.

"The United States, Russia, Europe, and India have all completed their Mars exploration missions, and we in China must not fall behind. So this mission must be successful! As a rocket team, we must ensure that there are no problems with the Long March 5B carrier rocket!"

"Comprehensive testing cannot allow any mistakes to occur in any link! In an aviation mission, a decimal point error may cost thousands of people several years of hard work and tens of billions of funds."

Everyone's expressions were serious, and no one wanted to go wrong with their mission. The huge pressure was not something ordinary people could bear!

"If you have any ideas, tell me."

He Jingcheng looked at the crowd, who were silent. The Long March 5 launch vehicle was a relatively mature series and there were basically no problems. That’s why the Long March 5 was chosen for this Mars probe launch mission.

"Team leader, I have a rocket improvement plan." Du Xingyu stood up and spoke.

Everyone in the research team looked at him. Today was Du Xingyu's first official day at work. Did he cause trouble on his first day? Some people are secretly unhappy.

"Oh, what do you think?" He Jingcheng was a little surprised, although he also thought Du Xingyu was a talent. But there is a gap between talents and real rocket engineers, and the difference between the rockets produced by schools and real launch vehicles is even greater.

According to He Jingcheng's idea, Du Xingyu still needs to be cultivated for a few years. Who knows that on the first day, he has already stepped forward.

"I have made a recovery plan for a heavy-duty launch vehicle. Can you demonstrate it?" Du Xingyu asked.

"Okay!" He Jingcheng smiled, but he didn't think Du Xingyu could make any reliable plan.

But it is also a good thing to let young people suffer a little.

Other team members thought the same thing, and they didn't pay much attention.

Du Xingyu turned on the projection screen in the conference room and began to explain his rocket recovery plan.

"Everyone knows that the reason why I can come here and work with you is that I made a small recyclable rocket. But what I want to say now is that this recyclable rocket plan is actually a simplified version of the heavy-duty launch vehicle I designed. As long as we make some changes, we can achieve the same effect on a heavy-lift launch vehicle."

As soon as Du Xingyu started talking, someone questioned: "Do you know how different a real heavy-lift launch vehicle is from the toys you made in school?"

Du Xingyu looked at him. He was a middle-aged man with a Chinese character face and thick eyebrows. His name is Tao Ran, and he is the deputy leader of the rocket research and development team.

Tao Ran was not friendly to Du Xingyu's face and tone. In fact, he had been very opposed to Du Xingyu since before he joined the group.

Tao Ran believes that the Xingkong No. 1 launched by Du Xingyu is just a toy and will be recycled with good luck. There is a huge gap between them and real rockets. Such students should start from the bottom instead of taking on such an important position as a rocket engineer as soon as they arrive!

Like Tao Ran, some people in the research team were not enthusiastic about Du Xingyu. What genius? Which of these rocket engineers, experts in dynamics, mechanical engineering, electrical, and intelligent systems, was not a genius when they were students?

"Potter, of course I know the gaps. So I still need your help to supplement this plan of mine." Du Xingyu said, "If you have any opinions, you can patiently listen to me and then raise them."

"I suggest you discuss it later." Tao Ran said directly, "Any idea made without experience in practice is just talk on paper."

The atmosphere in the conference room suddenly became awkward. It was clear that the engineers headed by Tao Ran did not approve of Du Xingyu and opposed him.

Liu Yuan expressed his opinion and said: "I have already read Du Xingyu's plan, and I think it is worthy of your study. The task is not busy now, let's listen to him first."

Although Liu Yuan did not serve as the team leader or deputy team leader, he was the technical advisor of his institute and a leading figure in the aerospace industry. Whenever he spoke, Tao Ran could only shut up and obey.

But everyone was still a little dissatisfied, feeling that Liu Yuan was taking care of his students.

Du Xingyu began to explain his plan. At first, everyone looked at it with a casual attitude, but gradually, their expressions became more and more serious!

Putting aside their personal attitudes and experiences, the researchers and rocket engineers here are all people who are passionate about research and space exploration.

Du Xingyu's plan is clear and well-founded, and he even conducted analysis under various simulated situations. There is nothing wrong with using computer software to simulate experiments.

With such detailed preparation, even if you just want to find out some problems, it will be a little difficult for a while.

Until after watching it, none of the experts in the conference room was the first to speak out. They were all thinking carefully about the plan, trying to justify it and find its shortcomings.

For a while, there was silence in the conference room. Liu Yuan was the first to break the silence and said: "I have read Xiao Du's plan in advance and studied it. I personally have not found any major problems. From a theoretical point of view, it can be implemented."

Team leader He Jingcheng said with emotion: “If I hadn’t seen it with my own eyes, I wouldn’t have believed it was made by a newcomer who had just joined our research team!”

"If this plan can be successfully implemented, we can save the country tens of billions of funds every year! Our country's aerospace engineering will definitely usher in great development!"

The cost of each rocket launch is hundreds of millions, or even billions. If Du Xingyu’s rocket recovery plan is successful, the rocket can be launched repeatedly, which is of great significance!

"I admit that this plan does have merit!" Tao Ran expressed his attitude, "but the results of computer simulation experiments cannot prove that it is feasible in actual operation."

He still has doubts about Du Xingyu's ability.

Everyone was talking a lot, some were supportive and some were skeptical.

Du Xingyu saw this and said: "Everyone, as you said, whether the plan is feasible or not depends on actual experiments. I suggest that this plan be implemented on the Long March 5B carrier rocket that we use to launch the Mars mission. ! Once successful, it will save billions in launch costs for the first time!"

"Even if it fails, the plan I designed will not affect the rocket launch, and our losses will be minimal."

The rocket recovery plan designed by Du Xingyu only comes into effect after the rocket is successfully launched. Even without its recovery system, the rocket would naturally disintegrate and crash into a pile of garbage.

As soon as Du Xingyu's suggestion was put forward, the discussion in the conference room became more intense!
