Li Saipu replaced Zhao Hanyuan as the dean of the Chongshi Research Institute, which caused many speculations in the public. A person who has served as the dean since its establishment has always had outstanding achievements. He resigned after three Nobel Prize winners appeared in the institute. Although the level remains unchanged, it still makes people confused.

Long Jianhua didn't come out to explain. Life was his own, so he didn't have to care about other people's thoughts.

He was not free to explain. Although gallium nitride and graphene have been successful, he will also withdraw his main energy, but he still needs to continue to pay attention. Mechanical design and materials are his next direction and need to invest more energy. Although the management of Chongshi Group and the Bank Group will not participate in daily life, the general direction and daily monitoring cannot be left behind. In addition, his own capital operation, he has to communicate with Kang Liwei and Yuan Fanqi several times every month. Therefore, he is even busier...

Zhao Hanyuan didn't say much, but after the handover was completed, he explained to the media who came to interview: Management and scientific research have conflicts, and he has been the president for so long, so it's time to concentrate on scientific research.

After Zhao Hanyuan resigned from his position as dean, the progress of engine research was like a plug-in. New plans were proposed one by one, and different types of engines began to appear, from small to large, from energy-saving to power of 4,000 horsepower, six types appeared in less than a year...

When deciding on the rocket engine plan, more than 80 people from majors in machinery, materials, chemistry, thermodynamics, etc. participated, and Long Jianhua was also one of them.

After listening to the team's introduction, they all started to ask questions or ideas about issues that they care about in their professional fields.

Someone asked, "Why is the engine's inner shape rough and not as good as a mirror?"

The team responded, "This is a new attempt, but not without scientific evidence."

He did not directly explain the reason, but just responded vaguely.

In fact, this is a reference to the experience of the Soviet Union. They used this form under the suggestion of several scientists with good mathematical skills, with the purpose of making high-temperature airflow turbulent near the inner wall, thereby increasing the heat exchange efficiency by more than 3 times.

Among the engine designers, six came from the Soviet Union, and brought this technical idea by the way.

This is the benefit of "learning" and the benefit of different sources of personnel. When various ideas meet and various advantages are summarized together, the starting point of research will be improved...

When the question was almost the same, Long Jianhua asked, "Why don't you consider liquid oxygen methane, but continue to use kerosene and liquid oxygen?"

Zhao Hanyuan responded, "Someone has tested liquid oxygen methane, and some people in our project team have also proposed it, but in the end, it is believed that if the engine is to be formed as soon as possible, kerosene liquid oxygen is the fastest."

A chemist shook his finger, "I also have this question. Compared with other fuels, methane is the least likely to coke, and its cooling performance is much higher than kerosene. It has a small viscosity and is not easy to accumulate carbon. Its theoretical ratio is higher. These are summarized by American rocket engineers."

"I think that since we have already entered this field, we must set a benchmark that cannot be measured by speed."

This was what Long Jianhua wanted to say, but he took the lead.

Zhao Hanyuan thought in his heart, but he was determined to make some achievements quickly, so he had the idea of ​​eagerness to achieve success when the project plan was finalized.

Another project team member defended, "Kerosene liquid oxygen engine has proven to be very successful and is currently the mainstream. We have adopted a number of own technologies and some of the latest achievements in the world; for methane liquid oxygen engines, I think we can serve as the next research project."

Long Jianhua looked at him steadily.

This way of considering problems does not conform to the model of Chongshi Research Institute. Here, there is no continuation. As long as others have new ideas that make sense, they need to refer to them and then argue, rather than quibbling.

Zhao Hanyuan glanced at the man and said lightly, "Actually, the methane liquid oxygen solution is also one of the first options we consider. But when we were internally proof, we felt that we could launch a new engine faster."

Long Jianhua said slowly, "For kerosene liquid oxygen engines, I don't know if you have considered adverse factors. The kerosene contains sulfur and will increase carbon deposits. Why does the US technical standards limit the pressure of the combustion chamber? I think the big reason is that there is no problem found."

"So, when we consider this engine, we cannot only consider whether it is mature, but also consider the long-term future. If we can make no sulfur in kerosene, we can consider this; if we cannot deal with sulfur, the kerosene solution will never be adopted."

This sentence is equivalent to vetoing the kerosene plan.

He is the honorary dean and the investor. His words have absolute weight compared to the rest of the people.

Moreover, what he said was some of the inside stories that the people present had not yet learned.

Zhao Hanyuan nodded, "Okay. We will abandon the kerosene solution and use the remaining fuels. This time we consider methane, and we will continue to study dimethylhydrazine, liquid hydrogen, etc. in the future."

After this question is settled, we will discuss other issues...

After the meeting, Zhao Hanyuan found Long Jianhua and said embarrassedly, "Mr. Long, I am a little anxious. Originally, we also discovered the problem of the US standard, but in order to achieve results as soon as possible, we did not conduct in-depth research on this aspect."

"The reason why Gundam Cheng defended himself was to achieve results as soon as possible. In fact, he was originally the proposer of the methane plan and was convinced by other team members."

Long Jianhua refused to comment, "What we pursue is not a day or night, but a certain height, and then continue to move to a high ground. This is how we walked through it before, but we are still persisting, and we will still go like this in the future."

Zhao Hanyuan felt a little embarrassed, "Speaking of this, the main responsibility lies with me, and I am a little eager for quick success and instant benefits."

Then I laughed at myself, "I couldn't hold back when I saw new achievements in other institutes appear one after another. When I was the dean, I didn't have this mentality; as a result, I became a comparative mindset when I sank into actual work."

"It seems that if you want to achieve some results, you must first adjust your mentality."

Long Jianhua asked with a smile, "Did you come up with the plan of milling grooves and brazing outer wall?"

He shook his head, "This is Soviet technology, which has been successfully tested by practice. The technology has not yet been completely released. It is just because our team has talents from the Soviet Union that we know that those designs were calculated by mathematicians and physicists in our institute, and the thermal conductivity of the inner wall of the combustion chamber has been greatly improved."

Long Jianhua nodded, "It seems that it is right for us to recruit a large number of Soviet scientific researchers."

Zhao Hanyuan laughed, "We took that step so correctly. Many people have already developed good research results."

Then he sighed, "It seems that I am still unable to stick to my heart and take advantage of the situation. I just want to see the so-called results quickly."
Chapter completed!
