At present, the salaries of Chinese scientists, especially high-level scientists, have risen sharply, and although they cannot be compared with the annual salaries of European and American countries, which are often hundreds of thousands of dollars or even millions of dollars, there are tens of thousands, or even tens of thousands of yuan a month, which is equivalent to tens of thousands, hundreds of thousands of dollars, which is a lot higher than that of Soviet scientists, and it is still rising.

When the Soviet Union collapsed and the ruble depreciated, the income gap between Chinese and Soviet scientists would further widen, not to mention a gap of several times, or even dozens of times, and it would be extremely attractive at that time.

Seeing that the scientists working for China are dozens of times their own income, even if other scientists can bear to admit it, his wife, his children, and his joining will not admit it, and they will definitely force him to go to China.

After deciding that he wanted to persuade the central leaders to agree to cooperate with the Soviet Union in the development and production of large transport aircraft, Guo Zhuocheng thought about what other projects were urgently needed by China, and China could not completely obtain technology from the United States or other European and American countries for the time being. ”

When Guo Zhuocheng was deep in thought just now, Qian Xuesen didn't bother him with words. If it is someone else, seeing a person talking to him and getting distracted, he must be a little annoyed in his heart, feeling that the other party is disrespectful to him. However, as a scientist, but a big scientist, this kind of thing is commonplace, because many scientists have this "problem", because no matter what these people do, it is easy to think of their own projects and scientific research, and many times when talking to others, a flash of inspiration comes to their minds, and they don't care about everything around them. Immediately organize in your mind, track down, analyze it, where will you care about talking?

Some can even maintain this state of dementia for a long time, some laugh inexplicably, and some shake their heads and sigh inexplicably, in the eyes of outsiders, they are just fools and have no temperament at all. Only fellow scientists can understand and accept it, and generally when they encounter this situation, the other party will wait silently. For fear of interrupting the other party's thinking, for fear that the flash of inspiration will disappear because of this.

Although Guo is not a scientist, Qian Xuesen has always regarded him as a scientist, and there is no doubt that he will be as brilliant as other scientists.

Hearing Guo Zhuocheng suddenly ask him about this, he said with a smile: "Hehe." You're so smart, you thought of it at once. ”

Guo Shucheng asked strangely, "What did I think of?" ”

Qian Xuesen smiled: "Boy, don't pretend, does this show that you are more shrewd?" How could a superior just let you watch a test flight of an airplane? ”

Guo Shucheng asked in surprise: "Could it be that we have also made a breakthrough in aerospace?" ”

Qian Xuesen smiled and asked, "Boy, you really don't know that the main purpose of our visit today is to watch the space launch, right?" Tremendous progress has been made in other fields, and we spend so much money on aerospace every year, and we must make some achievements in order to be worthy of the organization and the people, right? ”

Guo Shucheng blurted out: "It won't be the launch of 'Shenzhou 1', right?" ”

Qian Xuesen frowned and said, "Shenzhou No. 1? When did we have a project with such a title? Is it a space project? Why haven't I heard of it, Xiao Guo, are you presiding? ”

Guo Zhuocheng was stunned for a moment, and his heart was soon happy: it seems that he is still preconceived. When I think of aerospace, I think about the Shenzhou series of spacecraft and Tiangong in my previous life. However, this life is different from the previous life, especially the spacecraft technology is certainly very different from the previous life, because the spacecraft designed by China is now greatly influenced by the technology of the United States, and is very little influenced by the technology of the Soviet Union.

Because Sino-Soviet relations are showing signs of thawing. It is impossible for China to obtain space technology from the Soviet Union, and perhaps Chinese scientists do not know anything about Soviet space technology. Since it is different from the previous life in terms of technology. And the time of launch is more different, and the name of the spacecraft is naturally more likely to be different.

In the previous life, China's manned space launch began with Shenzhou-1, and the launch time of Shenzhou-1 was on November 26, 1999, that is, after 15 years now.

Guo Zhuocheng hurriedly shook his head and smiled: "No, no, I don't preside over any scientific research projects, I can't be busy on Qionghai Island, and I'm not a scientist, how can I preside over scientific research projects that you don't even know." I thought that the spaceship flew into the sky, and since it was a ship, it flew up to dance with the gods, so it was called Shenzhou. ......, Professor Qian, what name do we define for it? Chang'e, Weaver Girl or Celestial? ”

Qian Xuesen sighed at this time, glanced at Guo Zhuocheng a little suspiciously, and said: "We call it Kuafu, which is the Kuafu who chases the sun in ancient mythology." ......, however, I now think that what you said about Shenzhou is good, Shenzhou 1, Shenzhou 2, Shenzhou 3, 4, and 5 in the future, very good, there is no need to change the name every time like the United States, what 'Mercury', 'Gemini', 'Apollo', 'Space Room', 'Columbia' Space Shuttle or something. ”

Guo said sincerely: The United States also has a variety of space shuttles such as the "Challenger", "Discoverer", "Atlantis" and "Endeavor". However, in January 1986, the "Challenger" exploded in the air 72 seconds after launch, killing all seven astronauts on board.

"The explosion of the 'Challenger' space shuttle that occurred the year after tomorrow, should you tell the Americans in advance? ......, forget it. Who knows if it will explode in this life? Even if I say it in advance, people may not believe it, and it is easy to arouse their suspicions. Guo thought to himself, "As for the fact that the 'Columbia' disintegrated and crashed over northern Texas on February 1, 2003, and the director zhì also killed all seven astronauts, let's talk about it then." ”

Guo Shucheng asked suspiciously: "We call it Kuafu?" ”

Qian Xuesen said: "What? Do you think it's bad? Is it because the final outcome of Kuafu is that he dies of thirst and is unlucky? It doesn't matter, this time we are just experimenting, there are no people in it, and we are accumulating experience in the future. Praise the father chasing the sun, we take his spirit, and admire his persistence. ”

Guo Shucheng said with a smile: "I don't feel any bad luck, I just think that a big man's name is not as gentle as a woman's name." ......, will we take the Soviet Union's one-time spacecraft approach, or will we take the American space shuttle that can be used multiple times? ”

Qian Xuesen said: "We adopt a single-use spacecraft model, but I don't know if we have a lot in common with the Soviet Union. ......, do you like the space shuttle mode? ”

Guo Zhuocheng said: "No, I prefer the mode of the spaceship, which is safe, simple and reliable. ”

Qian Xuesen said: "That's good. When I saw you just now, after watching the test flight of our plane, I thought that we wanted to build a big plane, a big military transport plane, and to keep pace with the United States. ”

Guo Shucheng smiled: "You're laughing at me, right?" I'm not stupid enough to command you experts as a technical layman, am I? ”

Qian Xuesen said: "We have also conducted many arguments, and finally believe that the spacecraft model is more suitable for us, easy and can inspire the confidence of our astronauts, and can reduce technical risks and save project funds." ”

Guo Zhuocheng said very agreeably: "Now our aerospace technology has just started, and we don't need to carry much material into space, and there is a spacecraft that is enough for us." If technology advances in the future, more supplies need to be sent into space, and it will be too late to rebuild the space shuttle. ”

There is a significant difference between a spacecraft and a space shuttle, that is, the former has no wings and is a metal lump shaped like a cylinder, while the space shuttle has wings, just like a large airplane. Both are large rockets, but because of their different structures, they return to Earth in different ways. Because the spacecraft has no wings, it cannot generate lift when flying, and can only return in a ballistic or semi-ballistic way, with the result that the aerodynamic overload and landing error are large, and the return adopts the method of splashing on the sea surface or landing straight on the wasteland.

This landing method has high requirements for astronauts, requires long-term training, and also has a certain danger to the life safety of astronauts, and at the same time because of the impact landing with the ground or sea surface, it is a one-time spacecraft, and because the space is small and cannot transport large components, the number of astronauts is small, and it cannot fly in space alone. Its advantage is that the structure is relatively simple, there is no need for complex aerodynamic control surfaces, and there is no landing mechanism and related devices, so the reliability and safety are high. As long as the landing control technique is passed, the spacecraft and the astronauts in the spacecraft can come back safely.

The space shuttle, on the other hand, has wings, and when it returns to the earth, it enters the atmosphere to gain enough lift, and the longitudinal and lateral distances can be adjusted by controlling the magnitude and direction of lift, so that the space shuttle can accurately land on the runway and can be partially reused. It also has a much smaller overload, i.e. acceleration and deceleration are slow throughout the entire process from take-off to return to the surface, which greatly reduces the physical demands on the astronaut. It can transport more astronauts and supplies and large components, and it can fly in space independently, but it is expensive, technically demanding, and risky.

The Chinese and Soviet spacecraft have not had major safety problems for decades, while two US space shuttles crashed and exploded, killing more than a dozen astronauts.

Of course, the reborn Guo Shucheng is not willing to choose the space shuttle model, that thing is just a fame, and there will be no such need for decades to come, it is too wasteful. Only a country with a high level of science and technology and abundant funds like the United States can grit its teeth and hold out for a period of time, and other countries cannot.
