You say you have an iron will, are you serious?

Chapter 280: Will you be stressed when NASA launches a rocket?

"Some technical discussions on rotating detonation engines"

“...After the oil and gas mixture is ignited, in a very short time of microseconds, the flame rushes towards the unburned oil and gas mixture at a certain speed, triggering a detonation wave, completing combustion in a very short time, and releasing a large amount of energy... …”

"High energy efficiency, high environmental protection, diversified fuels, intelligent control, and other application expansion... It is simpler than pulse detonation, can be started at 0 speed, and does not require intake fans, compressors and other structures..."

"...When the engine's external output power W is zero and the engine incoming mass flow rate is m, F=m(u3-u0), so the thrust F and cycle thermal efficiency eta satisfy F=m(√2√ηthQ+u/0 -u0￣)...It can be seen that the theoretical propulsion performance of the engine depends on the entropy increase △Scomb caused by combustion in the combustion chamber..."

The next day, after returning to the capital, Zhao Mo drafted a report and handed it in. He wrote a report on the principles and applications of rotating detonation engines.

This report was written quickly, thanks to his ability, and also to the detailed explanations given by Academicians Jiang, Li and others about the Emei engine, which allowed him to qualitatively improve his knowledge of fighter engine manufacturing. Combined with the accumulation in the development process of rocket engines, he cannot say that he has become a master in the field of aviation development, at least he is a master.

Of course, the importance of this engine and my personal opinion that it is not very urgent are also written down.

After handing it over, Zhao Mo said hello to Su Yaohua, and then went to the 11th Research Institute to continue to follow up on the follow-up test run of the high-thrust engine.

As soon as they arrived there, the team reported to him the test results during this period. The performance was very good. Although they occasionally encountered some problems, they were solved quickly.

Zhao Mo looked at their test drive records, especially the problems that arose and their solutions. He saw some minor flaws, but he did not mention them. Instead, he praised them emphatically and encouraged them to continue to use their subjective initiative. Finally, he He changed the subject and said that it would be more perfect if it was slightly adjusted.

When everyone in the team heard his expression, they all naturally had happy smiles on their faces.

After checking the records, Zhao Mo probably had a good idea, and thought that if nothing unexpected happened, the verification would be done in April or May next year.

Another busy day~

At night, everyone chose to go back because the upcoming work did not require staying up late every day.

On the way back in the car, when Zhao Mo was thinking about the problem, Liu Zhirong asked him a mathematical question: "I want to prove this conjecture. Do you think I have a chance?"

Because of him, even if they are busy until late every night, his six students Lu Cheng, Liu Zhirong, Li Guoguo, Zhou Fei, Wang Pan, and Zhou Mingze, like him, never forget to study or work in the car. The work is to study the principles of the engine and try to solve the difficulties encountered; the study is to learn mathematics, and their core task is to learn mathematics well.

Zhao Mo glanced at the title on the notebook: Every positive integer can be expressed as the sum of at least two positive rational numbers, which is an unproven harmonic conjecture.

He did not answer Liu Zhirong directly, but asked instead: "Some people persist because they have hope, and some people have hope because they persist. Which one do you want to choose?"

Liu Zhirong was startled at first, but when he realized what he meant, his face turned red and he said quickly: "I know, I will work hard."

Then get ready to sit back down.

When he asked Zhao Mo just now, he actually wanted to ask Zhao Mo if it was possible for him to solve the "reconciliation conjecture" problem. On a deeper level, he wanted to give Zhao Mo some hints. It is a kind of negative thought and a waiting thought. This is not a true scholarly attitude.

Those who are truly knowledgeable should believe that they can solve the problem themselves and do it directly, instead of asking others first and then deciding whether to do it themselves.

So, he is putting the cart before the horse.

It is precisely because of this that Zhao Mo's words exposed his little thoughts, and he was naturally extremely embarrassed.

You know, he is not only Zhao Mo's "student", he was also Zhao Mo's roommate, and his dual identity makes him even more sensitive.

"Wait a minute~"

Zhao Mo stopped him, then took his pen and notebook, and spoke while writing: "This conjecture is still very difficult, involving the decomposition and combination of positive integers. I just thought about it, Now that I have some possible ideas, let me tell you about them and see if you or they can make a breakthrough on this idea."

After only five minutes, Zhao Mo stopped writing, returned the pen and notebook to him, looked at Lu Cheng, Li Guoguo and others and said, "You can also try it if you are interested~"

It's not that he can't bear it or takes special care of it.

In fact, this was the first time that his students tried to prove some mathematical conjectures. Before, they had always been taught on their own, and more often than not, they were used as tools.

It’s rare to be so motivated outside of work, so of course you need to be encouraged.

"Thank you!"

Liu Zhirong whispered thank you and then sat back down.

Lu Cheng, who was sitting next to him, immediately put his head in front of him and said enthusiastically: "Let me see~"

Liu Zhirong: "..."

Good guy, you want to make everything exciting?

When he was about to speak, Zhao Mo had already turned around and continued thinking about his own problem, but Li Guoguo, Zhou Fei and others immediately gathered around and said like Lu Cheng, "Let me have a look too~ "

"Okay~"

Liu Zhirong took a long breath and opened the notebook.

Lu Cheng and others watched for a moment and then realized what Liu Zhirong had just asked.

However, they had no time to be surprised that Liu Zhirong secretly wanted to prove the mathematical conjecture, because the large handwriting behind the conjecture was Zhao Mo's, and it was Zhao Mo's proof of the "harmonic conjecture".

“……正整数都可以表示为若干个素数的乘积加上1，8可以表示为2*3+1，14可以表示为2*7+1……”

Very simple and sloppy, which is also in line with Zhao Mo's usual style for them.

They all could see that Zhao Mo just gave an idea. How to prove the conjecture according to this idea depends on their own luck.

Perhaps, Zhao Mo himself didn't know whether his idea was correct or wrong.

Of course, they would not think about this. After reading this idea, they only had one thought: "How should we solve it according to the instructor's idea?" When they returned to the dormitory, Lu Cheng and Liu Zhirong were still thinking. this problem.

When Wang Chao saw them, he saw that both of them were in a daze, walking without focus. He couldn't help but laugh and asked: "Your body is back at school, but your mind is still at the research institute~"

Hearing the sound, the two of them came back to their senses.

Lu Cheng lay down on the bed, took a deep breath and said, "It's so comfortable! It's so difficult. These conjectures are really not the work of humans. Zhirong, I give up, you can continue your research."

Liu Zhirong didn't answer him and went to wash himself.

Wang Chao glanced at Lu Cheng and asked with a smile, "What's your guess?"

Lu Cheng replied: "I don't know where Zhirong was stimulated by the harmonization conjecture. He still felt that life was too boring, so he wanted to find some excitement. He was so busy at work, and he still wanted to prove this mathematical conjecture! It's true !”

"Reconciled conjecture?"

Wang Chao took a deep breath and said, "This is a big problem. Does Zhao Shen know?"

Lu Cheng smiled and said, "Of course I know. Liu Zhirong asked about it just now, and then Zhao Shen gave us an idea."

"what?"

Wang Chao was shocked, stood up subconsciously, and said in a voiceless voice: "Is it so good?"

Was he really shocked, providing ideas for proving mathematical conjectures to his students? How generous is this?

In academia, I don’t know how many tutors take away the credit of fake students and give a little bit of help to the students who have worked hard to achieve results, which is a good tutor. Those who can give students some advice on academic issues and career support are considered to be peerless mentors who serve as apprentices.

Provide students with ideas for proving mathematical conjectures?

Not only have I never seen this kind of mentor, I’ve never even heard of it!

"Okay? It's always been like this, isn't it you?"

Lu Cheng sat up and looked at him in surprise and asked.

Wang Chao: "..."

Good guy, he didn’t dare to answer this.

Saying yes is not true.

Saying no, Professor Qiu has always been very kind to him.

"Okay, I get it~"

Seeing that he was hesitant to speak, Lu Cheng immediately realized that he had asked the wrong question just now, so he quickly changed the subject and said, "Do you want to read it? If you want to read it, it's over there. Just look through it yourself~"

As he spoke, he pointed at the notebook Liu Zhirong had just left on the bed.

Wang Chao hesitated again: "Isn't this bad? Zhao Shen showed this to you, I am an outsider..."

Before he could finish his words, Lu Cheng interrupted him and said, "Zhao Shen never cares about outsiders. Just watch it if you want. It's just an idea. If you really want to prove it, you still don't know how to start." .”

"Okay~ okay."

Wang Chao's expression was stagnant, then he slowly walked over, picked up the book and started reading.

After reading it, Wang Chao was a little surprised and confused, but in the end he shook his head and didn't say anything. He just thought in his heart: "Although it is just a simple idea, it is too generous~"

He put the notebook back and talked about other things.

"By the way, Zhao Shen talked about building a lunar base on Weibo. Is there anything you can disclose? Satisfy my curiosity."

he asked with an interested smile.

Lu Cheng shook his head and said, "No, how could he tell us about such a big thing?"

"That's right~"

Wang Chao was a little disappointed, but understood, and then said: "The Internet said it was a response to America's launch of the Ares rocket and the plan to return to the moon. I don't know whether it is true or not. But America will launch their Ares rocket tomorrow. The whole world is paying close attention to the rockets, and the excitement is aroused. Do you think they can be successfully launched?"

Lu Cheng said without hesitation: "It will probably succeed. America and NASA's technology is still very powerful."

Wang Chao nodded and said, "I think so too."

After saying that, he couldn't help but tease him: "So, are you feeling any pressure?"

Lu Cheng said nonchalantly: "What kind of pressure do we have? We are very relaxed. The pressure is all shouldered by tall people, Zhao Shen. But I see that Zhao Shen is in a good mood today, so there shouldn't be any pressure, right? After all, a thousand We have developed engines with a thrust of 100 tons and are already thinking about building a moon base, so America’s plan to return to the moon is nothing.”

Wang Chao: "..."

He is very envious~

At this time, it was daytime on the other side of the Pacific Ocean in America.

With many people around the world watching, NASA has made final preparations for their Ares rocket at the launch site~

　On the last day of 2023, I wish all book friends a happy New Year.

　　I don't like to talk, I am very transparent, and I code silently, and I don't say much. Here, I still have to say something to wish you all the best in 2024!
