January 1997, a suburban base in the suburbs of place is far away from the city center, but even so, people like Xue Jinquan still find it very magical. "Do you think what Lao Chen is saying is really reliable? Can the Longyuan space transport spacecraft really send people into space without a rocket launch?" "Nonsense, this topic has been discussed since September last year, and they only thought of testing now. I don't know what those people do for a living, and where do they get so many testing methods? If it were us, we would have started mass production long ago, why would we bother with so much trouble?" "Fuck, Old Chen is awesome. A few years ago, I knew he was going to develop the economy, but I didn't expect he could actually build such a big satellite. Wow, the Longyuan space transport ship can transport twelve people to the moon at once. Isn't the next step to transport a hundred or a thousand people?" "Why don't you say that Lao Chen is the biggest variable in our class? We are all classmates. When we were still in class, he started to invent things. Do you still remember the car seat belt? Hey, others don't know about this thing, but he knows it." "Okay, stop arguing, we're about to take off." As veterans of Zhenhua Research Institute, Xue Jinquan and his group are the backbone of the institute. Even though they are old, they are in their fifties and have not completely retired. They can still engage in scientific research. For example, all of them participated in the research and development of the 500,000-kilometer quantum entanglement signal transmission technology. Although they cannot stay up all night to do scientific research like young people, they are experienced and are good helmsmen for the entire project. At this moment, in front of them, a triangular spacecraft started its engine. The sound was very small, and Xue Jinquan and the others didn't hear any movement at all.

On the other side of them, Chen Guohua stood next to Gu Baishun and the others and said with a smile: "Old Gu, I told you that this spacecraft can take off normally and can make a round trip to the moon within 20 hours. The purpose of this test is to go to the Tianhe Moon Base and bring the three astronauts back to Earth. It is now 10:30 am Beijing time. Believe me, we will be back here tomorrow morning." Gu Baishun and the others nodded absentmindedly, not taking Chen Guohua's words to heart. The reason is very simple. They are all very clear about the relevant flight data of Longyuan. In the past few months, Gu Baishun and his colleagues have held several meetings with Chen Guohua because of the lunar base acceleration plan mentioned by Chen Guohua. In addition, Gu Baishun, Wang Dingzuo, Sun Shubo and others received relevant data from the Longyuan every once in a while, so they were very familiar with the data in this area. There was no other way. If they wanted to confirm the situation of the Longyuan, they needed to know more data. It’s just because this spacecraft was developed by Chen Guohua. To be more precise, he used Chang'e artificial intelligence and built it with the help of robots. In everyone's perception, there is nothing wrong with robots being able to participate in simple, repetitive mechanical work like that in factories. However, the Longyuan space transport spacecraft is an interstellar spacecraft. It needs to undertake the 380,000-kilometer transportation mission from the Earth to the Moon, so safety is of utmost importance. What's more, it is a spacecraft for transporting astronauts, so it needs to complete various tests. At first, no one believed that if it weren’t for the product developed by Chen Guohua, Longyuan would not have been able to enter the test sequence to avoid wasting resources. Even after entering the test, I was still faced with all kinds of difficulties. In short, it has been like this for the past few months. Chen Guohua himself is also busy, and it can even be said that he enjoys transporting materials to the moon and speeding up the construction of the Tianhe lunar base. Anyway, just transport the relevant materials over in advance, and when they arrive, they can start working. After all, no one is more suitable to be the transporter than Chen Guohua. Under the gaze of everyone, the Longyuan took off smoothly. After taking off, its flying speed began to accelerate, and it accelerated at an incredible speed. Everyone returned to the conference room and stared at the display screens in front of them. There were a lot of data on them. These data clearly and intuitively told everyone the various data on the Longyuan at the moment.

The transport spacecraft participating in the test this time was actually the prototype completed by Chen Guohua before, rather than the official model of Longyuan that was manufactured a second time later. Even so, the data of the Longyuan prototype spacecraft are very stable. "Fuck, it has already broken through Mach 2? It hasn't even left the atmosphere yet. If it leaves the atmosphere, won't it break through Mach 10?" Shi Zhiqing couldn't help but swear, which attracted many people's attention. Among the many display screens, the most eye-catching data are speed and altitude. As the Longyuan space transport spacecraft took off at a rapid speed, various data changed dramatically, and the most noticeable one was the speed. Shi Zhiqing and his colleagues are all scientific research workers and are extremely sensitive to these data. No one expected that the Longyuan space transport spacecraft was so awesome. It broke various speed records before it was even 10,000 meters in the air. You should know that the aircraft that normally fly at an altitude of 10,000 meters in the stratosphere are passenger planes of various airlines, and their flying speed is only about 900 kilometers per hour. Although these passenger planes are more considered in terms of operating costs and other issues, the speed of the passenger planes cannot be too fast. After all, the Concorde in the 1960s proved with blood and tears that a passenger plane that is too fast is not necessarily a good thing. Because the Concorde had too many operational difficulties, such as high noise, high fuel consumption, and poor riding experience, all these are the reasons why major airlines were reluctant to purchase it. Although the economy of the Longyuan does not need to be considered, there are still requirements for sound insulation and riding comfort, right? It can't be too exaggerated, right? You have to know that this is the spacecraft that transports astronauts to the moon. When they are on Earth, because of the atmosphere, if sound can be transmitted in the air, it would be very terrifying. Running so fast at this time would be a fatal blow to the astronauts in the spacecraft. "Any decibel data? What? Only twenty-four?" Xue Jinquan and his team also noticed this, because even though they were still at an altitude of 10,000 meters and their speed had exceeded Mach 2, the decibel level inside the Longyuan spacecraft was only 24. Isn't this too incredible? As we all know, the normal voice of human speech is around thirty to sixty. Thirty decibels is the volume of speaking softly, sixty decibels is the volume of speaking loudly, and below thirty decibels is the golden sound in a quiet state, such as in a library, a quiet night, etc. So, when Xue Jinquan and others noticed this data, they all exclaimed in surprise. Gu Baishun and his colleagues were not professionals, but there were professional scientists nearby to help explain, so they understood it. "Old Chen, how did you do that? This is really amazing!" Hearing the exclamations of Zhang Jichuan and others, Chen Guohua smiled and said: "As you all know, I designed the Overlord space transport ship. At that time, I thought about the noise issue. If this problem cannot be solved, then this ship will undoubtedly fail." Regarding the issue of aircraft noise reduction, if we refer to Rolls-Royce cars, it would be a failure because they reduce noise by increasing the weight of the car. A Rolls-Royce car, in addition to its vehicle structure, has about 130 kilograms of noise reduction materials. Such noise reduction materials are actually acceptable for a car. But for spacecraft, it is highly undesirable. Therefore, Chen Guohua reduces noise by developing new noise reduction materials. The so-called new materials are not just the various sound insulation cotton materials on the market, but more about reducing noise from the source. For example, the surface coating of Longyuan has a noise reduction function itself, which can reduce noise by at least 60%. After passing through the hard metal partition, the noise can be reduced to 95%. The last layer is the inner mezzanine of Longyuan. Here, the noise has been reduced to more than 98%.

There is also the engine noise, which is also a difficult point that Chen Guohua has to tackle. After listening to Chen Guohua's statement, everyone realized how much work and effort he had put in. But until this moment, everyone still cannot understand, that is, can robots really replace the human brain and complete such difficult research and development work? "The research and development work is certainly not done by robots. Instead, Chang'e intelligently controls the robots and performs precise manipulation under the program I set." When Chen Guohua heard this, he immediately laughed and said: "I have said before that I developed a robot that can be manipulated to the micron level, and with the control of Chang'e artificial intelligence, I was able to build the Longyuan space transport spacecraft with their help." "Of course, most of the technology on Longyuan was actually completed by me, rather than relying solely on Chang'e artificial intelligence and robots." After Chang'e's artificial intelligence reached the middle level of the beginner stage, it became unstoppable. So what he just said to everyone was actually reserved. To be honest, during the entire development process of Longyuan, Chang'e artificial intelligence helped him complete more than 80% of the work. All he needed to do was to complete some relatively difficult research and development work. Chen Guohua did not need to think about most of the complicated calculation problems. He only needed to sample a few of the experimental data and conduct targeted checks. If there is something wrong with the result, then he must start over again. But a piece of data, such as the engine of the Longyuan space transport spacecraft, its maximum flight speed, temperature resistance and other performance, can all be displayed in digital form. If this engine has no data updates compared to its predecessor, or to be more precise, it is still the same, Chen Guohua will suspect whether there is something wrong with his initial research and development technology. However, until the prototype of the Longyuan space transport spacecraft perfectly passed all test data and completed various flight tests, there were still no problems, which showed that Chen Guohua's technology was completely fine. Not to mention the discussion of Chen Guohua and others, at this time, the Longyuan broke through the atmosphere and flew towards space at an even faster speed. Until the speed exceeded the second cosmic speed and was even accelerating, everyone in the conference room was completely stunned. The sound of inhaling continued. At this point, everyone finally understood why Chen Guohua said that it was possible to travel to the moon and back within 20 hours. Wow, he was really modest. Because at the current flying speed of more than 12 kilometers per second, a distance of 380,000 kilometers only takes hours. What's more, its speed continued to soar, and soon broke through the speed of kilometers per second. At this speed, it will be even faster, only eight point two hours. "Old Chen, you are really awesome. It seems that a round trip of 20 hours is no problem at all." After checking the current speed, Xue Jinquan quickly calculated the time required for Longyuan to reach the moon. He then checked other data and found that all the data were completely normal. Under such circumstances, all the boasts made by Chen Guohua actually came true. Just like what Chen Guohua boasted to them more than 30 years ago, everything has come true. From Peking University to BAIC Manufacturing Plant, to Zhenhua Research Institute, and to this moment, Chen Guohua has always been so awesome in his life. I never brag. I always do what I say and I always keep my word. Chen Guohua said a few humble words and the matter was almost over.

At this time, the Longyuan had already completely entered space and was escaping from the earth at an extremely fast speed. Gu Baishun and his team were talking to the astronauts on the Longyuan, asking about the relevant situation. After confirming that everything was fine, Wang Dingzuo and others were also very impressed. At this point, they had actually confirmed that the Longyuan space transport spacecraft developed by Chen Guohua was indeed very awesome. Agreeing to accelerate the Tianhe lunar base plan seems to be a very correct decision. The same is true for the spending of 300 billion RMB. "Lao Chen, it looks like we are going to lose, but we are happy to lose" Upon hearing this, Chen Guohua also started laughing. The Longyuan space transport spacecraft will definitely be able to reach the moon smoothly and bring back the astronauts on the moon within twenty hours. Just for this reason, the 300 billion RMB was worth it. But at this moment, Gu Baishun received an emergency call, saying something happened in Southeast Asia. (End of this chapter)
