Chapter 173 Yes, please understand a little

At this time, Su Yiguo thought of some other questions.

"Xu You, you said you are very concerned about the aerospace field. So, you also know other things besides aerospace materials and aerospace software simulation?"

Xu You is indeed very concerned about the aerospace field. As long as the aerospace news can be seen on the Internet, Xu You basically knows it.

During these days of internship at Suzhou Satellite Launch Center, Xu You read a lot of internal information in the field of aerospace, and the amount of relevant knowledge is richer than before.

"Well... I understand a little."

But Xu You didn't answer very confidently. After all, compared with those professionals in the aerospace field, Xu You is just an intern.

"Okay, then I'll ask a few questions."

Su Yiguo always felt that Xu You was not as simple as "understanding a little".

Since this is the case, Su Yiguo would rather examine Xu You through some professional questions.

"Xu You, what are the main technical difficulties do you think our new generation of heavy launch vehicles are in terms of technology?"

After thinking for a while, Xu You replied seriously:

"I think the main difficulty of General Engineer Su should be in engine technology and large arrow body technology."

Hearing Xu You's answer, Su Yiguo raised his eyebrows again.

This Xu You is really OK!

In a short while, you can talk about the key points of the problem.

Such an answer is definitely not as simple as an ordinary aerospace enthusiast.

In addition to the engineers responsible for rocket development.

Even staff members within the space agency system may not be able to answer so accurately.

"Let's talk about engine technology." Su Yiguo continued to ask.

"Okay, General Engineer Su. He used the third-type engine technology on Zhengtu No. 9."

"First of all, it is Liquid 130. Liquid 130 is a 480-ton refueling cycle dual-chamber kerosene engine at sea level. This engine has more experience and is an improvement to the previous generation."

"Next, the vacuum thrust of Liquid 90 and Liquid 90 is 220 tons, which is a graded combustion cycle hydrogen and oxygen engine. We have less experience in this engine and it is very difficult to develop. But if it can be completed, it is definitely technically

a big breakthrough.”

"Finally, Liquid 79. Liquid 79 is a 25-ton expansion cycle hydrogen and oxygen engine. It can be said that it is an engine that we have no experience at all. The difficulty of R&D can be imagined. Of course, if the research is successful, we will be in the world.

Take the lead."

When talking about these things, Xu You, who usually seems not good at speaking, suddenly became boastful.

Su Yiguo knew that Fan Liangzhong had already talked about these things when Xu You and others visited the exhibition hall.

But Xu You was able to remember these completely, but even added a lot of his own ideas. This is indeed a very amazing thing about Xu You.

"General Engineer Su, our first Zhengtu 9 rocket should not be launched at the Suzhou Satellite Launch Center?"

At this time, Xu You suddenly asked.

"Hmm? What do you say?"

In fact, according to the current plan, what Xu You said is indeed true.

But Su Yiguo was also very curious about how Xu You came to this conclusion.

"General Engineer Su, because as far as I know, our Suzhou Satellite Launch Center is mainly responsible for manned launch missions, low-Earth orbit launch missions, and solar orbit launch missions. Like the various large payloads of my country's space stations, cargo spacecraft , as well as the launch missions of massive communication satellites, polar orbit satellites, moon and Mars rovers, should be launched at the Zibei Space Launching Site in the South China Sea Province."

The Zibei Space Launch Site in Nanhai Province is the southernmost aerospace launch site in China.

Because its latitude is low, it can help with a larger linear velocity close to the equator and the centrifugal phenomenon caused by inertia, greatly reducing rocket fuel consumption.

Compared with other high-latitude space launch sites, the carrying capacity of the same model can increase by about 10%.

In addition, because it is located near the sea, it is convenient to transport rockets through sea transportation.

When the rocket launch ends, the rocket wreckage will fall directly into the sea.

There is no need to evacuate personnel like when launching in inland launch sites.

Hearing Xu You's explanation, Su Yiguo nodded again.

"Yes, your understanding of China Aerospace is indeed very deep. According to the current plan, the first launch of Zhengtu 9 will be at the Zibei Space Launch Site. There is another thing you may not know about, Zibei Launch

The field is also preparing for manned spaceflight. If it goes well, future manned moon landing missions will also be carried out at the Zibei Space Launch Site."

"The Zibei Space Launch Site is also about to prepare for the manned launch mission?"

Xu You was also a little surprised by this news.

This is indeed something Xu You didn't know before.

After all, if you want to be competent for manned space launch missions, the space launch site needs to be fully equipped.

So far, China has only the Suzhou Satellite Launch Center, which has the conditions to perform manned launch missions.

However, because of the unique advantages of the purple shell launch site at latitude.

It can indeed make the rocket's carrying capacity better.

In the future, it is also a general trend to carry out various manned launch missions at the Zibei Space Launch Site.

"Yes, this is already in preparation. Of course, even if our Suzhou Satellite Launch Center may not perform the Zhengtu 9 launch mission, there are still many other important tasks in it, including rocket development and software simulation.

Engine test drive, etc.”

These tasks are equally important than rocket launches.

After some inquiry, Su Yiguo was completely impressed by Xu You.

Previously, Su Yiguo also believed that if a person studies too many fields, he will inevitably be distracted and will only try it out in every field.

Faced with Xu You now, Su Yiguo really has nothing to be picky about.

Xu You is really an interdisciplinary talent who can take into account multiple disciplines.

"In this way, Xu You. Then you will participate in the research and development of coating materials first. When this part of the work is completed, we will check the progress. If you want to go back to school, you can leave. If you are not in a hurry to go back,

It's OK to stay here for a while."

Su Yiguo had a vague idea of ​​Xu You staying with him.

A person like Xu You is no longer just an excellent intern, but a key figure who is really likely to make significant contributions to the team.

"Okay, General Engineer Su. I shouldn't be in a hurry at the school. The main thing is that there is a superconducting project, and the others are just taking the final exam or something."

"So, do you no longer need to attend classes?" Su Yiguo asked.
Chapter completed!
