Top Student

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

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

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

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

"Well... I understand a little bit."

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

"Okay, let me ask you a few questions."

Su Yiguo always feels that Xu You is not as simple as "understanding".

That being the case, Su Yiguo wanted to investigate Xu You carefully through some professional questions.

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

After Xu You thought for a while, he replied seriously:

"Chief engineer Su, I think the main difficulty should be in engine technology and large rocket body technology."

Hearing Xu You's answer, Su Yiguo frowned again.

This Xu You is really good!

All of a sudden, you can get to the point of the problem.

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

Except for the engineers responsible for rocket development.

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

"Let's expand on the engine technology." Su Yiguo continued to ask.

"Okay, Mr. Su. On the Zhengtu 9, the engine technology of Type 3 is used."

"First of all, it is YIFA 130. YIFA 130 is a sea-level 480-ton afterburning cycle dual-chamber kerosene engine. We have more experience with this engine, and it is an improvement over the previous generation."

"Next, the liquid hair 90. The vacuum thrust of the liquid hair 90 is 220 tons, which is a staged combustion cycle hydrogen-oxygen engine. We have relatively little experience with this engine, and it is very difficult to develop it. But if it can be developed, it will definitely be technically a major breakthrough."

"Finally, the liquid hair 79. The liquid hair 79 is a 25-ton expansion cycle hydrogen-oxygen engine. It can be said that it is an engine that we have no experience at all. The difficulty of research and development 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 seemed not good at speaking, suddenly became boastful.

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

But Xu You was not only able to fully remember these, and even added a lot of his own thoughts, this is indeed a very remarkable thing about Xu You.

"Mr. Su, our first Zhengtu-9 rocket, shouldn't it be launched at the Suzhou Satellite Launch Center?"

At this time, Xu You suddenly asked.

"Huh? How to say?"

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

It's just that Su Yiguo is also very curious about how Xu You came to this conclusion.

"Mr. 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. And various large payloads and cargo spacecraft like our country's space station , as well as the launch missions of large-mass communication satellites, polar-orbiting satellites, and lunar and Mars probes, should be launched at the Zibei Space Launch Site in Nanhai Province."

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

Because of its low latitude, it can help the large linear velocity close to the equator, and the centrifugal phenomenon caused by inertia, so that the fuel consumption of the rocket is greatly reduced.

Compared with other high-latitude space launch sites, the carrying capacity of the same type of rocket can be increased by about 10%.

In addition, because its location is close to the sea, it is convenient to transport rockets by sea.

At the end of the rocket launch, the wreckage of the rocket will fall directly into the sea.

There is no need to evacuate personnel like when launching from an inland launch site.

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

"Yes, your understanding of Huaxia 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 one more thing you may not understand, the Zibei launch The field is also preparing for manned spaceflight. If all goes well, future manned missions to the moon will also be carried out at the Zibei Space Launch Site.”

"Zibei space launch site is also preparing to start a manned launch mission?"

Xu You was also a little surprised by this news.

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

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

So far, Huaxia only has the Suzhou Satellite Launch Center, which has the conditions to carry out manned launch missions.

However, because of the unique advantage of the latitude of the Zibei launch site.

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

It is also an inevitable trend to carry out various manned launch missions at the Zibei Space Launch Site in the future.

"Yes, this is already under preparation. Of course, even though our Suzhou Satellite Launch Center may not carry out the launch mission of Zhengtu 9, there are still many other important tasks, including rocket research and development, software simulation, Test run of the engine and so on."

These tasks are equally important compared to rocket launches.

After some questioning, Su Yiguo was completely convinced by Xu You.

Before, Su Yiguo thought that if a person studied too many fields, he would inevitably be distracted, and he would only scratch the surface in various fields.

Facing the current Xu You, Su Yiguo really had nothing to criticize.

Xu You is really an interdisciplinary talent who can take care of multiple disciplines.

"That's it, Xu You. After that, you will participate in the research and development of coating materials first. We will see the progress after this part of the work is completed. If you want to go back to school, you can leave. If you are not in a hurry to go back, in It’s okay to stay here for a while.”

Su Yiguo had a vague idea in his heart that he wanted Xu You to stay by his side.

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

"Okay, Mr. Su. I shouldn't be in a hurry at the school. The main thing is that I have a superconductivity topic, and the rest is to take the final exam or something."

"So, you don't need to go to class anymore?" Su Yiguo asked.
