Technology's opening live broadcast to build rockets

"Have you thought about it?" Wang Wei asked, "How about we do a spacecraft orbit design? We have done this before and have experience!"

Du Xingyu shook his head.

"Let's do the structural design of aerospace components. Let's be more specific about this." Lu Liang pushed up his glasses and said with his mobile phone, "Most of the former seniors and sisters did this. Their graduation projects have reference value!"

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

"Be a rocket?" The three roommates looked at him and asked in confusion: "Why do you want to be a rocket? Isn't it too difficult?"

"The rocket is a whole, which is dozens of times more difficult than making parts for us!" Wang Wei said.

"More than dozens of times!" Zhao Qingquan said, "Ordinary models will definitely not work. We must make them according to rocket design principles. Just thinking about it makes me think it can't be done!"

"There is a certain feasibility." Lu Liang likes to collect data. He said: "Three years ago, several seniors in our college designed a small rocket with a liftoff height of 150 meters and a range of more than 250 meters. They also won the Outstanding Graduation Project Awards, I heard that they have all entered national scientific research institutions!”

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

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

"What?" Several roommates suspected that they heard wrongly.

"Brother, do you know what the stratosphere is? The stratosphere is more than ten kilometers above the surface. You want the rocket to fly so high? Why don't you fly out of the atmosphere?" Wang Wei complained.

"I also want to fly out of the atmosphere." Du Xingyu said regretfully, "It's just that our funds, materials and manpower are limited, so we can't do it yet."

"Stop joking!" Zhao Qingquan said, "People can fly more than a hundred meters, which is an excellent design. You still want to fly to the stratosphere? You can also recycle the launch vehicle! If we have this ability, we can't just sit here now Here, it’s at the National Space Administration!”

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

"Du Xingyu, stop talking nonsense. It's difficult to make any kind of rocket, even a rocket engine!" The students around him couldn't help but interject.

"You can do whatever you want. Anyway, I'm going to make a rocket. Do you want me to join you?" Du Xingyu stood up and asked.

The classmates around him looked at him with strange expressions. This guy is really whimsical!

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

Zhao Qingquan: "Wang Wei and I have the same view."

Lu Liang shrugged and said, "It's not that I don't support you. If you don't do a good job in your graduation project, it will affect your graduation assignment. There's no way you can succeed."

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

She has long hair and wears a white shirt and a blue pleated skirt. She has willow eyebrows and moon eyes, her skin is as white and soft as fine snow, and she is tall and has undulating lines.

Although it is just no makeup, it still gives people a bright and fresh feeling.

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

Xu Lianqiu is not only a high-IQ academic who was admitted to Hangzhou University in Suzhou, but also has an admirable good looks and is the dream lover of many boys.

"Yes." Du Xingyu nodded firmly.

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

"I want to make a medium-range launch vehicle, short-range ones are boring." Du Xingyu said.

Hearing his words, Xu Lianqiu's eyebrows moved and she said: "This is too difficult. It is estimated that it will be difficult for us to achieve our capabilities. Then I will design a miniaturized ion thruster."

Obviously, she also thought Du Xingyu's idea was too whimsical.

"Okay, does anyone else want to join? You only have one chance!" Du Xingyu looked at his classmates.

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

"This is a hell-level difficulty, impossible to complete." Everyone shook their heads.

"Well, it seems I have to do it myself." Du Xingyu had expected this situation for a long time, and he thought it was impossible before he got the technology simulator. But technology simulators can help him complete many designs, and it is not impossible to develop rockets on his own.

As senior students, they no longer have many classes to attend, and their classmates are all busy with their graduation projects.

Du Xingyu’s roommates decided to build a simulation device for capturing space junk with a flying fork as their graduation project.

And Du Xingyu began his own process of manufacturing recyclable rockets.

Technology Simulator: "Relevant information has been obtained, and the research progress of "Recyclable Rocket" is 10%."

After Du Xingyu collected some information about rockets in the current world, the research progress increased by ten percent.

As a student of Aerospace University, he has many advantages. For example, the school has a national-level laboratory. You can also apply directly to the school for materials used in making rockets, but the prerequisite is that it must be approved by the instructor.

These resources are all allocated by the state to cultivate aviation elites.

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

Normally, even with the simplest structure, or copying the structural design of other rockets, this work cannot be completed by Du Xingyu in a day or two.

However, on the technology simulator, Du Xingyu can directly simulate the structure and conduct structural testing and simulation experiments without spending any extra manpower and material resources.

If there are unreasonable or design loopholes, the simulator will standardize it and give corresponding reminders. In this way, his work efficiency is equivalent to that of a rocket research and development team.

After spending more than a day and using previous experience, Du Xingyu designed the body structure diagram of a small and medium-sized rocket on the technology simulator.

"The length of the rocket body is 7.6 meters. Considering the cost issue, a rocket thruster is installed on the main body, which must carry a liquid energy module. Since it is a recyclable rocket, a fuel module for a reverse air thruster must also be added... The cost is also increased……"

Rocket body materials and fuel are the largest parts of the budget. Du Xingyu's family is not rich, so it is quite difficult to bear the burden on his own, so he still has to apply to the school.

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