Chapter 3

"Have you made up your mind?" Wang Wei asked, "why don't we do a spacecraft orbit design? We have done this before and have experience!"

Du Xingyu shook his head.

"Do the structural design of aviation components. This should be more specific." Lv Liang pushed his glasses and said with his mobile phone. "Most of the former seniors and sisters did this. Their graduation design has reference value!"

"No, I'm going to be a rocket," said Du Xingyu.

"Make a rocket?" the three roommates looked at him and wondered, "why do you want to make a rocket? Is it too difficult?"

"The rocket is a whole, which is dozens of times more difficult than us to make components!" Wang Wei said.

"More than dozens of times!" said Zhao Qingquan. "Ordinary models certainly can't be made. We must make them according to the rocket design principle. Just think about it, we can't do it!"

"There is a certain feasibility." Lv Liang likes to collect data. He said: "three years ago, several senior students in our college designed a small rocket with a lift-off height of 150 meters and a range of more than 250 meters. They also won the excellent graduation design award. It is said that they have entered the national scientific research institutions!"

"But this kind of difficulty is relatively high. If we can get their data at that time, we may be able to copy it again!"

"No, it's not that kind of rocket." Du Xingyu still shook his head and said, "I'm going to design a recyclable launch vehicle that can fly to the stratosphere."

"What?" several roommates suspected that they had heard wrong.

"Brother, do you know what the stratosphere is? The stratosphere is ten kilometers above the surface, so you must make the rocket fly so high? Why don't you make complaints about the atmosphere?" Wang Wei Tucao.

"I also want to fly out of the atmosphere." Du Xingyu regretted, "but our funds, materials and manpower are limited, so we can't do it for the time being."

"Don't be kidding!" said Zhao Qingquan. "People fly more than 100 meters. They are all excellent designs. Do you still want to fly to the stratosphere? Recyclable launch vehicles! If we want to have this ability, we're not sitting here, but at the National Space Administration!"

Lu Liang analyzed: "your idea is very bold, but from the feasibility analysis, our probability of success is almost zero."

"Don't be ridiculous, Du Xingyu. It's hard to be a rocket or a rocket engine!" the students around couldn't help interrupting.

"You can do whatever you want. Anyway, I'm going to be a rocket. Are there any together?" Du Xingyu stood up and asked.

The students around him looked at him strangely. This guy is really whimsical!

"Cough." Wang Wei kindly reminded, "Du Xingyu, although we are roommates, your idea is too wild. I think it's better to be practical. Do some research on the structure of aviation parts."

Zhao Qingquan: "I think the same as Wang Wei."

Lv Liang shrugged and said, "it's not that I don't support you. If this graduation project is not done well, it will affect the graduation assignment. You can't succeed."

"Du Xingyu, do you really want to be a rocket?" a sister looked at him curiously.

She wore a ponytail, a white shirt and a small blue pleated skirt. With willow eyebrows and moon eyes, the skin is as white and soft as snow, the figure is tall and undulating.

Although it is only plain makeup, it still gives people a bright and fresh feeling.

Her name is Xu Lianqiu, the ground command center liaison in Du Xingyu's dream last night.

Xu Lianqiu is not only a high IQ academic bully admitted to Aviation University in Suzhou, but also takes into account the adorable ultra-high appearance. She is the dream lover of many boys.

"Yes." Du Xingyu nodded firmly.

"If it's a short-range recoverable rocket, I'm also very interested." Xu Lianqiu seems to want to join his research team.

"I want to be a medium-range carrier rocket, short-range is boring," Du Xingyu said.

Hearing what he said, Xu Lianqiu moved her willow eyebrows and said, "it's too difficult for us to do so. I'd better design a miniaturized ion thruster."

Obviously, she also thinks Du Xingyu's idea is too whimsical.

"Well, is there anyone else who wants to join? There is only one chance!" Du Xingyu looked at the students.

"Can't do it, can't do it!"

"This is hell level difficulty, impossible to complete." people shook their heads one after another.

"Well, it seems that I have to do it myself." Du Xingyu had expected this situation for a long time. He thought it impossible before he got the technology simulator. However, the technology simulator can help him complete many designs, and it is not impossible to develop rockets by himself.

As senior students, they don't have many classes to attend. The students are busy with graduation design.

Du Xingyu's roommates decided to make a simulation device for space junk rope flying fork capture as their graduation project.

Du Xingyu, on the other hand, started his own process of making recyclable rockets.

Science and technology simulator: "relevant information has been obtained, and the research progress of recyclable rocket is 10%."

After Du Xingyu collected some rocket information in the current world, the research progress increased by 10%.

As a student of the University of Aeronautics and Astronautics, he has many convenient places. For example, the school has a national laboratory. The materials used to make rockets can also be applied directly to the school, but only if they are approved by the instructor.

These resources are allocated by the state to train aviation elites.

"First of all, I want to complete the design of the three major structures of the rocket, including the rocket body mechanism, power plant system and control system."

If it is normal, even the simplest structure, or copy the structural design of other rockets, this work can not be completed by Du Xingyu in a day or two.

However, in the science and technology simulator, Du Xingyu can directly simulate the structure and carry out structural test and simulation test without consuming any redundant human and material resources.

In case of unreasonable or design loopholes, the simulator will also be standardized and give corresponding reminders. In this way, his work efficiency alone is equivalent to that of a rocket R & D team.

Taking more than a day and using the previous experience, Du Xingyu has designed the arrow structure diagram of a small and medium-sized rocket on the science and technology simulator.

"The length of the rocket body is 7.6 meters. Considering the cost, the main body is equipped with a rocket thruster to carry a liquid liquid energy module. Since it is a recyclable rocket, it also needs to add the fuel module of the reverse air thruster... The cost increases..."

Rocket materials and fuel are the largest part of the budget. Du Xingyu's family is not rich. It's difficult for him to bear it. He still has to write an application to the school.

So Du Xingyu wrote a plan and went to the teacher's office in charge of laboratory management.
