With the support of Academician Su behind him, Lin Yu quickly completed the formation of the group with six people.

"What we're going to do is a reusable liquid engine, get it?" Lin Yu didn't say a word, and made the goal of this time clear.

Because he told Academician Su, he didn't need to repeat some approval activities with Academician Su here, nor did he need to write a paper application, just say hello in advance.

So they directly occupied a laboratory and conducted research in it.

In order to convince his team members of himself, Lin Yu showed his professionalism about this kind of rocket engine, which dispelled most of these people's suspicions, he was not a layman who only worked on materials, so what he said might be true.

In order not to make others too suspicious, Lin Yu did not throw out a perfect design drawing of a reusable liquid rocket engine at the beginning, but put forward an idea, and then slowly improved it with the team members.

Gradual progress is king.

"Team leader, can you look at this design?" A member of the team took him and sketched on the design sketch proposed by Lin Yu and proposed the design he came up with.

"I think there are some mistakes in your design, and you don't take into account the problem of flame propulsion at all, and our current rocket is a working fluid thruster, so it has to carry a lot of fuel."

"If we follow your design, we will have to reduce the amount of fuel carried, but the quality of the fuel we are currently using is already optimal, and if we do it again, we may not be able to gain enough momentum for the rocket."

Without Lin Yu to speak, an experienced person next to him saw the problem at a glance and immediately pointed out the right way.

"I think it could be designed that way." The experienced designer came up with his own design.

This time Lin Yu was impressed, and the design he took out was three points similar to the design given to him by the system, and the design of the rocket engine currently used was somewhat optimized.

But it's a bit of a fantasy to get to the point where it's completely reusable.

"I think it's okay...... "Everyone joins in, and you say everything you think.

Lin Yu was surprised after listening to the ideas of several people, and they said that among these optimization designs, some of the content that was already given by the system was already half of the content of the design drawings given by the system.

"System, is the design of the reusable liquid rocket engine you gave five years later?"

"Yes, host."

After getting the system's affirmative answer, Lin Yu knew that these people in front of him were probably the designers who would complete the fully reusable liquid rocket engine in five years.

However, Lin Yu did not ask the system, otherwise he would definitely get a negative answer, because the system had already told Lin Yu a long time ago that after the system went to Lin Yu, time became a closed loop, that is to say, after the system came, Lin Yu's invention of these is a piece of history, that is, something that will inevitably happen.

Lin Yu remembered the thoughts of each of them, and finally thought about it, splitting and summarizing everyone's ideas separately, "Look here......" he pointed to the draft design drawings, "If we use his ideas and transform some of them, theoretically speaking, we can make the thruster reuse a higher degree." ”

After a summary, Lin Yu was recognized by a group of personnel, "Consultant Lin's analysis is very correct, as long as we combine the ideas of all of us, we can improve a lot in the end." ”

"I think so, if on the basis of your changes, you can optimize this part of the pipeline, and then let these lines work like this, and finally change the material, I just came from the material group, you can see the performance of these materials."

Lin Yu took out the materials he specially copied and sent a copy to each team member, "I think these materials are more in line with the design than the materials we currently use." ”

"That's it, let's discuss it here for the time being, let's go back and look at these materials first, and finally think about what needs to be changed, and we'll discuss it tomorrow."

Lin Yu announced that today's work is over.

Lin Yu returned to the dormitory with the design sketches, and then synthesized the designs of the team members that he summarized to revise them together.

"Are you really here for our group?" Just as Lin Yu was revising the design drawings, Wang Hong walked in, and the work of their group was over.

"That's right." Lin Yu replied without raising his head.

"I'll see." Watching Lin Yu keep scribbling and changing, Wang Hong leaned over, ready to take a look at what work they were doing.

"Are you planning to make a reusable liquid rocket engine?" It should be said that Wang Hong is worthy of being a professional in aircraft engineering and design, and you can see at once what Lin Yu is studying.

Although Lin Yu had talked to him about this matter a few months ago.

"This is what your group did?" The more Wang Hong looked at it, the more surprised he became, these designs were so good, a little change could make the performance of some parts fully exerted, not to mention that there were so many new designs.

"yes, I put all the good ideas together to come up with this design."

Lin Yu drew all the results discussed today, and this sample drawing has a forty percent similarity with the system's drawings.

"Is that how you think about this design?" Wang Hong made a sound of sudden realization as he watched.

"I was inspired by this design, you see." Wang Hong was not polite, picked up the pencil that Lin Yu had just put down and drew on the picture.

Lin Yu didn't stop him, after all, it was a pencil drawing that could be erased, and he couldn't worry about these little things.

Looking at Wang Hong's sketch, Lin Yu found that his idea was very close to the design drawing given by the system, and it turned out that the real big guy designer was in his dormitory.

"I said, then do you want to come to our group, I think your design is very good."

"No, no." Wang Hong rejected Lin Yudu's invitation, "My additive manufacturing has not been solved." ”

"Don't think about it?"

"Not considered."

Wang Hong took advantage of his own inspiration and soon made a design sketch.

"No, how about you take a look."

"That's amazing." Lin Yu did not hesitate to praise, "But there is a little problem." ”

"What's the problem?" Wang Hong asked rhetorically, he felt that he had perfected the design very well.

"Look here." Lin Yu picked up the pen to revise, compared the design in his memory with the draft in front of him, and sure enough, he found a few different places, and these places are relatively hidden, which also has a certain impact on the performance of the engine.

"Not bad." Wang Hong looked at Lin Yu's modifications, and he also realized the effectiveness of these modifications.
