The Start Of Technology Live Broadcast To Build Rockets

Chapter 3 – I am going to build a rocket

“Have you figured it out yet?” Wang Wei asked, “Should 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. This is more specific.” Lu Liang pushed his glasses and said with a mobile phone, “Most of the previous seniors and senior sisters did this. Their graduation design has reference value!”

“No, I am going to make a rocket.” Du Xingyu said.

“To be a rocket?” The three roommates looked at him in unison, wondering: “Why would you want to be a rocket? Isn’t it too difficult?”

“The rocket is a whole, and it is dozens of times more difficult than ours to make parts!” Wang Wei said.

“More than a few dozen times!” Zhao Qingquan said, “Ordinary models are definitely not good. We have to make them according to the rocket design principles. Just thinking about it, I feel that we can’t do it!”

“There is a certain degree of feasibility.” Lu Liang likes to collect data. He said: “Three years ago, several seniors in our college designed a small rocket with a lift-off height of 150 meters and a range of more than 250 meters. He also won an excellent graduation project. I heard that they have all entered the national scientific research unit!”

“But this kind of difficulty is relatively high, if we can get their data at the 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 misheard.

“Brother, do you know the concept of the stratosphere? The stratosphere is more than ten kilometers above the surface, and you want the rocket to fly so high? Why don’t you fly out of the atmosphere?” Wang Wei vomited.

“I also want to fly out of the atmosphere.” Du Xingyu regretted, “It’s just that our funds, materials and manpower are limited, so we can’t do it for the time being.”

“Don’t be kidding!” Zhao Qingquan said, “They fly more than 100 meters. They are all excellent designs. Do you still want to fly to the stratosphere? You can also recycle the launch vehicle! We must have this ability, we are not sitting now. Here, it’s 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.”

“Du Xingyu, don’t be so nonsense, it’s difficult to make a rocket or a rocket engine!” The surrounding students couldn’t help but interject.

“You can do whatever you want. I’m going to make a rocket anyway, do you have one together?” Du Xingyu stood up and asked.

The classmates around looked at him strangely, this guy is really whimsical!

“Ahem.” Wang Wei kindly reminded, “Du Xingyu, although we are roommates, your idea is too unreasonable. I think it is better to be practical. Do some structural research on aviation parts.”

Zhao Qingquan: “I have the same opinion as Wang Wei.”(Read more @ wuxiax.com)

Lu 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 in this.”

“Du Xingyu, are you really going to be a rocket?” A girl looked at him curiously.

She wore a ponytail, a white shirt and a small blue pleated skirt. Liu Meiyue’s eyes are as white and soft as snow, with a tall figure and undulating lines.

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

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

Xu Lianqiu is not only a high IQ student of Suzhou Jinhang University, but also an admirable superb appearance, and is the dream lover of many boys.

“Yes.” Du Xingyu nodded firmly.

“If it is a short-range recoverable rocket, I am also very interested.” Xu Lianqiu seems to want to join his research team.

“I’m going to be a medium-range launch vehicle, short-range is boring.” Du Xingyu said.

Hearing what he said, Xu Lianqiu Liu’s eyebrows moved and said, “This is too difficult, and our ability is estimated to be difficult to do. Then I will design a miniaturized ion thruster.”

Obviously, she also thinks Du Xingyu’s ideas are too whimsical.

“Well, anyone else would like 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.” Everyone shook their heads.

“Well, it seems that I have to do it myself.” Du Xingyu had expected this situation a long time ago, and he thought it was impossible before he got the technology simulator. But technology simulators can help him complete many designs, and self-developed rockets are not impossible.

As senior students, they don’t have many classes to take, and the students are busy with their graduation project.

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

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

Science and Technology Simulator: “Relevant information has been obtained, and the research progress of “Recoverable Rocket” is 10%.”

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

As a student of the University of Aeronautics and Astronautics, he still has many convenient places. For example, the school has a national-level laboratory. You can also apply directly to the school for materials used to manufacture rockets, but the prerequisite is to pass the approval of the instructor.

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

“First of all, I will complete the design of the three major structures of the rocket, the body mechanism, the power plant system and the control system.”

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

But on the science and technology simulator, Du Xingyu can directly simulate the structure, and conduct structural tests and simulation tests without consuming any extra manpower and material resources.

In the event of unreasonable or design loopholes, the simulator will also be standardized and give corresponding reminders. In this way, his work efficiency alone can be worthy of a rocket research and development team.

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

“The length of the rocket is 7.6 meters. Taking into account the cost, the main body is equipped with a rocket pusher and carries a liquid liquid energy module. Since it is a recyclable rocket, the fuel module of the reverse air thruster must be added… increased……”

The rocket body materials and fuel are the largest part of the budget. Du Xingyu’s family is not wealthy, and it is quite difficult to bear it by himself, so 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.
