Chapter 171: Well, I understand it a little bit
At this time, Su Yiguo thought of some other problems.
"Xu You, you said you are very interested in the aerospace field. So, in addition to aerospace materials and aerospace software simulation, you also know other things?"
Xu You is indeed very concerned about the aerospace field, and he basically knows all the aerospace news that can be found on the Internet.
During his internship at the Suzhou Satellite Launch Center, Xu You read a lot of internal information in the field of aerospace, and his relevant knowledge became richer than before.
"Hmm... I understand a little bit."
But Xu You did not answer very confidently. After all, compared with those professionals in the aerospace field, Xu You was just an intern.
"Okay, let me ask you a few questions."
Su Yiguo always felt that Xu You's knowledge was not as simple as just "knowing a little bit".
In this case, Su Yiguo would like to examine Xu You carefully by asking some professional questions.
"Xu You, what do you think are the main technical difficulties of our new generation of heavy-lift launch vehicles?"
After Xu You thought about it for a while, he answered 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 raised his eyebrows again.
This Xu You is really good!
In no time, we can get to the point of the problem.
Such an answer is definitely not just as simple as that of an ordinary space enthusiast .
In addition to the engineers responsible for rocket development.
Even staff members within the space agency may not be able to give such an accurate answer.
"Tell us more about engine technology," Su Yiguo continued to ask.
"Okay, Chief Engineer Su. On the ZT-9, three types of engine technology are used."
"First, there is the Hydraulic Engine 130. The Hydraulic Engine 130 is a 480-tonne sea-level, regenerative cycle, twin-chamber kerosene engine. We have more experience with this engine, and it is an improvement on the previous generation."
"Next, we will look at the Liquid Engine 90. The vacuum thrust of the Liquid Engine 90 is 220 tons, and it is a staged combustion cycle hydrogen-oxygen engine. We have relatively little experience with this engine, and it is very difficult to develop. But if we can complete the development, it will definitely be a major technological breakthrough."
"Finally, the Liquid Engine 79. The Liquid Engine 79 is a 25-ton expansion cycle hydrogen-oxygen engine. It can be said that we have absolutely no experience with this engine, and the difficulty of its development can be imagined. Of course, if the research is successful, we will take a leading position in the world."
When talking about these, Xu You, who usually seems to be not good at speaking, suddenly became talkative.
Su Yiguo knew that Fan Liangzhong had already briefly explained these things when Xu You and others visited the exhibition hall.
But Xu You was not only able to remember all of this, he even added a lot of his own ideas. This is indeed what makes Xu You so remarkable.
"Chief Engineer Su, our first ZT-9 rocket should not be launched at the Suzhou Satellite Launch Center, right?"
At this time, Xu You suddenly asked.
"Hmm? What do you mean?"
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.
"Chief Engineer Su, 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. The launch missions of various large payloads, cargo spacecraft, and large-mass communication satellites, polar-orbiting satellites, and lunar and Mars probes for our space station should be launched at the Zibei Space Launch Center in Nanhai Province."
The Zibei Space Launch Center in Nanhai Province is the southernmost space launch center in China.
Because of its low latitude, the larger linear velocity close to the equator and the centrifugal phenomenon caused by inertia can greatly reduce the rocket fuel consumption.
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 of its location near the sea, rockets can be conveniently transported by sea.
At the end of the rocket launch, the rocket debris will fall directly into the sea.
There is no need to evacuate personnel as is the case when launching from an inland launch site.
After hearing Xu You's explanation, Su Yiguo nodded again and again.
"Yes, you do have a deep understanding of China's space program. According to the current plan, the first launch of the ZT-9 will be at the Zibei Space Launch Center. There is one more thing you may not know, the Zibei Launch Center is also preparing for manned space flight. If all goes well, future manned lunar missions will also be carried out at the Zibei Space Launch Center."
"Is the Zibei Space Launch Center also preparing to start manned launch missions?"
Xu You was also a little surprised about the news.
This was indeed something Xu You had not known before.
After all, if a space launch site wants to be capable of carrying out manned space launch missions, it needs to be fully equipped.
So far, China only has the Suzhou Satellite Launch Center that has the conditions to carry out manned launch missions.
However, because of the unique latitude advantages of the Zibei launch site.
It can indeed better utilize the rocket's carrying capacity.
In the future, it will be an inevitable trend to carry out various manned launch missions at the Zibei Space Launch Center.
"Yes, this is already in preparation. Of course, even if our Suzhou Satellite Launch Center may not carry out the launch mission of the ZTE-9, we still have many other important tasks to do, including rocket research and development, software simulation, engine testing, etc."
These tasks are equally important compared to rocket launches.
After some questioning, Su Yiguo was completely convinced by Xu You.
Previously, Su Yiguo believed that if a person studied too many fields, he would inevitably be distracted and would only have a superficial understanding of each field.
Facing the current Xu You, Su Yiguo really has nothing to complain about.
Xu You is truly an interdisciplinary talent who can take into account multiple disciplines.
"Okay, Xu You. You will first participate in the research and development of coating materials. Once this part of the work is completed, we will take a look at the progress. If you want to go back to school at that time, you can leave. If you are not in a hurry to go back, you can stay here for a while."
Su Yiguo had a vague idea in his mind that he wanted Xu You to stay by his side.
People like Xu You are no longer just an excellent intern, but a key figure who has the potential to make significant contributions to the team.
"Okay, Chief Engineer Su. I shouldn't be in a rush at school. The main thing is a superconductivity project, and the rest is taking final exams and so on."
"So, you don't need to go to class anymore?" Su Yiguo asked.
