The rise of nanometers

Suiren Company is busy with business, and Huang Xiuyuan, Lu Xuedong and others are also very busy.

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

With the excellent performance of passivated nitrogen 20 in the actual measurement process, we have seen its huge potential. As a rocket engine fuel, nitrogen 20 has advantages that surpass many existing rocket fuels.

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

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

In the field of aerospace, commonly used launch vehicles usually use liquid fuel; while solid fuel is generally used for ejection.

This is mainly related to the characteristics of the two fuels. The characteristics of liquid fuel are cheap price, high specific impulse, fine control of output power, and relatively complex engine structure; while the characteristics of solid fuel are convenient storage and high thrust. It allows the rocket to be stored and concealed for long-term mobile transportation before launch, and the engine structure is simple.

The strengths of both are the weaknesses of the other.

But the emergence of nitrogen 20 has broken some boundaries between the two, because the theoretical specific impulse of nitrogen 20 has reached 850.

As for liquid fuels known to have high specific impulse, currently the most powerful liquid hydrogen and liquid oxygen have a specific impulse of only about 457; the dinitrogen tetroxide + undimethylhydrazine commonly used in the Long March series has a specific impulse of only about 348.

[Note: Specific impulse represents the propulsion efficiency of the rocket, which is specifically defined as the duration for each kilogram of fuel to produce one kilogram of thrust. The unit is seconds. ]

Nitrogen 20 has the high specific impulse of liquid fuel, but also has the high thrust of solid fuel. In addition, the production cost is not high, so it is simply a coveted excellent rocket fuel.

Rockets using solid fuel can directly use nitrogen 20 as fuel, but the launch vehicle of the spaceport is not that fast.

After all, the liquid rocket route was previously adopted, but now it is necessary to switch to solid fuel, and many things need to be reconsidered.

Just thinking about the high specific impulse and large thrust of Nitrogen 20, the big guys in the domestic aerospace industry, even if they insist on gritting their teeth, must develop solid fuel launch vehicles, otherwise they will be sorry for the emergence of Nitrogen 20.

Therefore, the institutions participating in the joint project have gradually added five official research institutes, including the Aerospace Science and Industry, which are all actively participating.

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

The formula of passivated nitrogen 20 is only suitable for high-energy explosives. When used as rocket fuel, it must be readjusted to change the explosiveness into flammability.

The 41st Research Institute and the 46th Research Institute of the Sixth Academy of Aerospace Science and Industry, and the 41st Research Institute and the 42nd Research 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, the personnel at the Aerospace Port have some connection to 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 then placed it in a special testing chamber. Only 0.5 grams of the test chemical was ignited by the igniter.

boom!

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

"Failed."

"No, it's not a complete failure." Li Feng, a researcher at Harbin Institute of Technology on the side, pointed to some data. The explosion time on it was not as fast as before, and was delayed by about 0.84 seconds.

The fuel improvement team of the 42nd Institute of Aerospace Science and Technology, Zhang Kezhe's team also came up with a formula, and the test results were similar.

To passivate the nitrogen 20 fuel direction, the unit energy density of the fuel must be ensured, and the burning speed of the fuel must be controllable. Otherwise, it is not a fuel, but a high-energy explosive.

After reading Zhang Kezhe's team's experiment on improving the formula, Huang Xiuyuan actually had a mature fuel passivation formula for a long time, but he deliberately delayed the release of the formula to make it less obtrusive.

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

Been busy all day.

The bright moon hangs high in the sky at night, and in the staff restaurant of the headquarters, many Spaceport researchers who have come to participate in the fuel passivation project are gathering in groups around the dining table.

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

He Wen, who had worked in an official research institute before, had a good chat with the researchers at the Aerospace Port, and even tested these researchers from time to time to see if they were interested in switching to Suiren Company.

The task of poaching was naturally assigned to Huang Xiuyuan.

Even many of the researchers who led the team, such as Zhang Kezhe and others, were a little moved. After all, the treatment of Suiren Company was obviously better than that of the official research institute.

There is another reason, and that is the working atmosphere, which makes Zhang Kezhe and others envious.

In the internal structure of Suiren Company, the scientific research department is at the same level as the industry department and safety department, and is only responsible to the board of directors.

The current general manager of the scientific research department is Lu Xuedong, who has a typical background in science and engineering. In each of the subordinate institutions of the scientific research department, all the managers are deputies, which is completely different from the research institutes at the Aerospace Port.

The more important thing is that among the qualifications for entering the board of directors, there are more scientific researchers engaged in research than administrative personnel.

Because it is easier for scientific researchers to obtain shares, this is an invisible benefit brought by technological innovation, and it is also intended to encourage technological innovation.

Who wants to be dependent on others when you can be the master of the house?

Many young researchers within the system already have some thoughts. In life, sometimes money is not the most important thing, especially for scientific researchers who are in the high-income group, they pay more attention to dignity and reputation.

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

Many people who are purely academic are even happy to see the results and are secretly adding fuel to the flames.

These people also have their own little ideas, and the purpose is to create a sense of crisis and let the outsiders in the institute understand that there is no place for them to stay, and they have their own place to stay.

Although it seems that the catfish effect of Suiren Company is not too obvious at present, as time goes by, who can say clearly what will happen in the future.

In the private room on the second floor of the restaurant.

Huang Xiuyuan and Lu Xuedong were eating and discussing some recent events. He put down his chopsticks:

"Xuedong, where is your current research on other polygonal silicas?"

Lu Xuedong wiped his mouth and said: "One discovery is about pentagonal silicon oxide. The third team responsible for this material synthesized a silicon element in the past two days."

"Silicon?" Huang Xiuyuan became interested.

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

Made up of 9 silicon atoms?

Could it be... Huang Xiuyuan was thoughtful. If there were no accidents, it should be the silicon molecule in his memory.

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

The emergence of this material did not attract the attention of academia and industry at first, and it was not very advanced in terms of uses.

It was not until five years later that the special properties of pentagonal silicon oxide were discovered.
