Suiren Company is busy with business, while Huang Xiuyuan, Lu Xuedong and others are also so busy that they are not touching the ground.

The nitrogen 20 rocket fuel project jointly established by Harbin Institute of Technology and Suiren Company is not only involved in Harbin Institute of Technology and Suiren Company.

With the excellent performance of passivation nitrogen 20 in the actual measurement process, it has seen its huge potential. In terms of rocket engine fuel, the advantages of nitrogen 20 surpass many active rocket fuels.

It can be stored stably for a long time, and the storage conditions are not too harsh. In addition, the combustion products are non-toxic and have a large unit energy density.

Perhaps the only disadvantage is that nitrogen 20 is a solid fuel.

In the aerospace field, commonly used launch vehicles usually use liquid fuels; while in terms of solid fuels, they are generally used for ejection.

This is mainly related to the special characteristics of the two fuels. The characteristics of liquid fuel are cheap, higher than the impact, and can finely control the output power. The engine structure is relatively complex; while the characteristics of solid fuel are convenient storage and large thrust, which allows rockets to store for a long time and carry out concealed motors before launching, and at the same time, the engine structure is simple.

The advantages of both are the shortcomings of the other party.

However, the emergence of nitrogen 20 broke some boundaries between the two, because the theoretical specific impulse of nitrogen 20 reached 850.

As for liquid fuels, which are known as high specific impulse, the liquid hydrogen and liquid oxygen that are most capable of evaporating is only about 457%; the nitrogen tetroxide + dimethylhydrazine commonly used in the Long March series is only about 348% of evaporation.

[Note: The bias represents the propulsion efficiency of a rocket, which is specifically defined as the duration of each kilogram of fuel, which is generated in seconds.]

Nitrogen 20 has no high specific impulse for liquid fuel, and has high thrust of solid fuel, and is not high in production costs. It is simply the coveted excellent rocket fuel.

Rockets that use solid fuel can directly use nitrogen 20 as fuel, while the launch vehicle at the space port is not that fast.

After all, when I took the liquid rocket route before, I now switched to solid fuel, and many things need to be reconsidered.

Just thinking about the high specific impact and high thrust of nitrogen 20, the big guys at the domestic aerospace industry must develop solid fuel launch vehicles even if they grit their teeth and insist on it, otherwise they will be sorry for the appearance of nitrogen 20.

Therefore, five official research institutes have been added to the joint project, including Aerospace Science and Technology, all of which have actively participated.

Huang Xiuyuan and Lu Xuedong have been busy with this matter these days.

The formula of passivation nitrogen 20 is only suitable for high-energy explosives, and when used as rocket fuel, it must be readjusted to change the explosiveness to combustion.

The 41st Institute, 46th Institute of the Sixth Academy of Aerospace Science and Technology, 41st Institute, and 42nd Institute of the Fourth Academy of Aerospace Science and Technology, have all sent many researchers here.

These four institutes are all engaged in solid fuel and solid fuel engines.

In fact, among the personnel at the Aerospace Office, there are more or less contacts with Harbin Institute of Technology, and many of them are Huang Xiuyuan's senior brothers.

In the secondary auxiliary experimental area on the side of the materials laboratory.

Huang Xiuyuan readjusted the passivation formula and put it in a special testing room. Only 0.5 grams of test medicine was ignited by the igniter.

boom!

The test drug suddenly exploded in an instant, detecting various sensors in the detection room, and feeding real-time data back to the computer.

“Failed.”

"No, it has not been completely failed." Li Feng, a researcher at Harbin Institute of Technology, pointed to some data. The explosion time on it was not as fast as before, and was delayed by about 0.84 seconds.

Zhang Kezhe's team from the Fuel Improvement Team of the Institute of Aerospace Science and Technology 42 also came up with a recipe, and the test situation was similar.

The fuel direction of nitrogen 20 must be passivated, and the unit energy density of the fuel must be ensured, and the combustion speed of the fuel must be controlled. Otherwise, it will not be fuel, but high-energy explosives.

After reading the improved formula experiment of Zhang Kezhe's team, Huang Xiuyuan had actually had a mature fuel passivation formula, but in order not to be too abrupt, he deliberately pressed the time of the formula.

On the other hand, he also tried to train the scientific research department of Suiren Company.

I've been busy all day.

The moon was hanging high at night, and in the restaurant at the headquarters, many aerospace researchers who came to participate in the fuel passivation project were gathering around the dining table in groups of three or five.

They and the researchers from Suiren Company showed two completely different styles.

He Wen, who had been in the official research institute before, had a good chat with researchers at Aerospace, and even tried to check whether these researchers were interested in changing jobs to Suiren Company from time to time.

The task of poaching was naturally explained by Huang Xiuyuan.

Even many researchers in the team leader, such as Zhang Kezhe and others, were a little moved. After all, the treatment of Suiren Company is obviously beyond the official research institute.

Another reason is that the working atmosphere makes Zhang Kezhe and the others envious.

In the internal structure of Suiren Company, the scientific research department, the industry department and the security department are on the same level and are only responsible to the board of directors.

The current general manager of the scientific research department is Lu Xuedong, a typical science and engineering background. Among the subordinate institutions of the scientific research department, the management personnel are all deputy, which is completely different from those research institutes in the Aerospace Port.

What is more important is that there are more scientific researchers engaged in research than administrative management personnel when entering the board of directors.

Because scientific researchers are more likely to obtain shares, this is an invisible benefit brought by technological innovation and is also to encourage technological innovation.

You can be the master of your family, who is willing to rely on others?

Many young researchers in the system already have some ideas. Sometimes money is not the most important thing for a person to live a lifetime, especially for scientific researchers who are high-income groups, they pay more attention to dignity and fame.

Various research institutes are actually well aware of the poaching of Suiren Company, but they have no way to stop it.

Many people who are purely academic even enjoy seeing it, secretly adding fuel to the fire.

These people also have their own little thoughts, the purpose is to create a sense of crisis and let those outsiders in the institute understand that if they don’t leave their master here, they will have their own way to leave their master.

Although it seems that the catfish effect of Suiren Company is not very obvious yet, as time goes by, who can explain what will happen in the future clearly?

In the second floor of the restaurant.

Huang Xiuyuan and Lu Xuedong were having dinner while discussing some recent things. He put down his chopsticks:

"Xuedong, where are your research on other multilateral silicon oxides now?"

Lu Xuedong wiped his mouth and said, "One of the discoveries is about the pentaneous silicon oxide. The third group responsible for the material synthesized a silicon element two days ago."

"Silicon element?" Huang Xiuyuan became interested.

Lu Xuedong explained: "It is a special silicon element, which is different from the single-crystalline silicon and polycrystalline silicon discovered before, but a molecule composed of 9 silicon atoms."

What are the 9 silicon atoms?

Could it be... Huang Xiuyuan was thinking, if there was no accident, it should be the silicon molecule in his memory.

The emergence of this silicon molecule was also the first new material made of polylateral silicon oxide at that time.

The emergence of this material did not attract the attention of the academic and industrial circles at the beginning, and it was not very prominent in terms of its use.
