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

Chapter 273 The turbulent domestic researchers

"The world of physics and mathematics is about to explode~"

Li Dong thought subconsciously while looking at Zhao Mo's paper on the N-S equation published in Nature.

Even though Zhao Mo only advanced the research work on the N-S equation to n≥3, which is only one step closer than the previous n≥4, it is still a great achievement, otherwise "Nature" would not publish it.

To a certain extent, Zhao Mo's paper basically declares the non-existence of the N-S equation and the smoothness. This is very important to a lot of great minds in the physics and mathematics circles who have been pursuing the existence and smoothness of the N-S equation. It is undoubtedly a huge blow.

It is a huge blow to those industrial fields related to turbulence, fluid mechanics and other research, as well as to those practicing engineers and experts.

This is tantamount to saying that there is no way forward!

Now it’s the top!

For example, scientists who study airplanes still don’t know why airplanes can take off. Human beings just took advantage of this phenomenon and made the plane fly, but there was no explanation for "why". Then, scientists believe that if the existence and smoothness of the N-S equation are solved, they can answer "why".

But now, Zhao Mo jumped out and told everyone that this cannot be solved! How fucked up is this~

If it were an ordinary person, the big guys would have already rallied to attack.

But the person who published the paper was Zhao Mo, a powerful young man in the field of mathematics. He was the man who had just helped China build a 1,000-ton high-thrust rocket engine. Who dares to refute his thesis and his conclusion easily?

Li Dong himself immediately became depressed, because rocket building was also related to this, and he was engaged in rocket design.

When a rocket goes from the earth's surface to outer space, it not only needs to overcome gravity, but also needs to overcome air resistance and the influence of airflow during high-speed flight.

The flight speed of a rocket is often a few kilometers per second, or even more than ten kilometers per second. The so-called sound barrier problem encountered by aircraft is just a child's problem in rockets. The speed of sound is only 340 meters per second, which is far different from the speed of rockets.

At high speeds of several kilometers or more than ten kilometers per second, the airflow in the atmosphere has an extremely severe impact on the rocket.

The rocket that can better deal with these effects will be better designed. It will not only fly high, but also fly stably and have a high payload.

What is value for money?

This is value for money!

All countries in the world today are pursuing it tirelessly.

Now that Zhao Mo says it can't be done, does he want to study it further?

Li Dong scratched his head and read the paper again. There were comments from Tao Zexuan and other great figures in mathematics and physics. Even Witten, a master of both physics and mathematics, was alarmed and came out to support Zhao Mo. This The cards are strong and the credibility is at least 99%.

"So, I should give up later?"

Li Dong thought regretfully.

In fact, does he not have a dream in his heart to solve the N-S equation?

After thinking about it for a while, Li Dong then read the paper twice and studied it carefully before looking at other scientific research results published on it.

He couldn't help but read the following content, because most of it was not in his research field, and he just saw it as something new.

Half an hour later, he put down "Nature" and picked up the other internal reference book placed under "Nature" and started reading it.

Internal Reference is a confidential publication compiled by the Ministry of Science and Technology and the Ministry of Industry and Information Technology. It publishes some technical information on domestic confidential projects and is only open to specific researchers.

This internal reference information is closely related to his research field, and it is technically detailed. Many key points and details are written in it, for fear that others will not understand it.

Ranked first in this internal reference material is the summary report on "Technology Related to One Thousand-Ton High-Thrust Rocket Engines". The reporter is Zhao Mo and Zhao Mo's Wudaokou and Eleventh Academy research teams.

"Hey, just in time to study~"

Li Dong's eyes suddenly lit up and he became interested.

"Mr. Li, it's dinner time. Let's have dinner together?"

It was lunch time at this time. A colleague walked by and saw that he was still reading, so he leaned in and greeted him.

"Go ahead, I'm not hungry yet."

Li Dong glanced at the other party casually and said, then he focused on the internal reference materials again and concentrated on studying.

"Okay~"

The colleague shook his head, not thinking there was anything strange, and left immediately.

In the design institute, most people are like Li Dong, who find it difficult to regulate their meals. After all, there is no food to study. When you encounter a problem or something wonderful, you have to finish it before you can think about doing anything else. Otherwise, you won’t be able to eat or sleep well.

"It's truly a genius idea~"

After just reading it for a while, Li Dong was amazed by the contents of this summary report, especially the innovation of the engine structure and the design of the overall solution, which were unique.

Among them, there are some very puzzling "whys", that is, why this engine is built like this. Li Dong looked at the back and saw the theory behind it.

"...Symmetric average version ~/B, regarding the equation /tμ=△μ+~/B(μ,μ), μ(0)=μ/0 does not satisfy =0..."

"...local theoretical velocity μ=0..."

……

Li Dong read it for a long time and typed the draft again before he finally found the "why" in it, but then a new "why" came into his mind: "Huh? Wait a minute? Isn't Zhao Mo on "Nature"? Publish a paper saying that the N-S equation will explode? Then here is the explanation..." At this moment, the CPU was almost dry-fired.

It was said earlier that it will explode, but here again the principles of existence and smoothness are applied. This is a contradiction.

After thinking for a moment, Li Dong realized that the paper published by Zhao Mo in "Nature" did not conflict with the summary report in the internal reference. The paper published by Zhao Mo in "Nature" was theoretical research, and perhaps there were other reports by him. Consider.

"Forget it, let's not think about that. This partially established theory seems to be applicable~"

Li Dong shook his head, brushed aside the issues that had nothing to do with him, and instead thought of his current rocket design work, and then got some inspiration.

The next moment, he took out a pen and paper, wrote down the theory and inspiration, and began to calculate.

……

Li Dong's reaction is just a microcosm of the many researchers from confidential units in China.

At the same time, in the 624th Institute of Xinjian City in Mianyang, Sichuan Province, Academician Jiang, who is currently responsible for the development of the Emei engine, was also looking through "Nature" and internal reference materials. He also put the two articles side by side for comparative research.

Institute 624 is also called the Gas Turbine Research Institute. It was originally located in Jiangyou and was newly built in Mianyang after the Wenchuan earthquake.

New environment, new beginning.

Academician Jiang's recent work is to do the final research on the Emei engine. This is an engine used in fifth-generation fighter jets. The design thrust has reached about 18 tons, which is close to the thrust of the America F-35 fighter jet, which reaches 20 tons. tons of engines.

This research does not mean that the engine has encountered difficulties and needs to be tackled, but the end of the problem, the final work.

Because the Emei engine has been successfully tested in 2006, it also completed the FRET, which is the pre-flight qualification test phase, in July not long ago.

Next, his goal is to achieve a successful test flight and officially put it into service in 2011.

The aircraft equipped with the Emei engine is my country's highly confidential J-20 fighter, which is codenamed by NATO as "Flame Fang" and is also the J-10 modified by the director.

"The overall situation may not exist, but it may exist locally?"

Academician Jiang looked at the summary report on the internal reference data with a thoughtful look on his face.

The next moment, he stood up and walked aside, dug out the test records of the Emei engine over the years from the database, and began to compare the test data one by one, including thrust, fuel consumption, air flow, temperature, pressure, boost ratio... Wait, wait, and then apply the formula.

Follow the theoretical formula set in the summary report of "Related Technologies for One Thousand-Ton High-Thrust Rocket Engines" and then test these data.

Soon, Academician Jiang jumped up and said with surprise: "It is indeed right!"

According to the theoretical formula in the summary report, although it was an application for rocket engines, he believed that aircraft engines should also comply, so he found the test data of Emei engines to verify it.

Sure enough, except for a few special ones, the test data of the Emei engine are very consistent with the theoretical formulas in the summary report. This means that his idea is right, and it also means that the theoretical formulas in the summary report can also be used for guidance. Aircraft engine design.

"Awesome! What a genius!"

Immediately, Academician Jiang praised excitedly and looked at the speaker who summarized the report: Zhao Mo.

He is devoted to the development of the Emei engine. Although he has paid less attention to the outside world in recent years, he still knows Zhao Mo as a person and knows that he is a great young scientist.

Zhao Mo developed a 1,000-ton thrust rocket engine. Academician Jiang was very happy when he found out about it. At that time, he was thinking about whether he should have a phone call with Zhao Mo to talk about fluid mechanics. It's just that I'm not familiar with it, and the Emei engine has been finalized and it's a critical moment, so I put it on hold for now.

He never would have thought that Zhao Mo's development of a thousand-ton thrust rocket engine would still affect him, in such a sudden and natural gesture.

After admiring it, Academician Jiang focused on those few special data and studied it again.

These data do not conform to the theoretical formula, or rather are different from the data derived from the theoretical formula.

"Is it a difference between reality and theory? Or are there still flaws in our Emei engine?"

Academician Jiang attaches great importance to this, and he is inclined to the possibility that the Emei engine is still defective.

At this stage, the design theory of aircraft engines is actually very mature. Scientists from all over the world believe that the inability to build one is purely an engineering problem. As long as the engineering problems are solved, the aircraft engine can be built. For example, high-performance materials and difficult processing techniques.

But now, Zhao Mo has given a brand new theory in his summary report. This is a major breakthrough, and as a result, a rocket engine with a thousand tons of thrust has been created.

If the theory is a new theory and if the results are significant, how can Academician Jiang not pay attention to them?

Half an hour later, Academician Jiang had not come to a conclusion, so he immediately got up and made a phone call: "No, I have to ask Academician Li to find Professor Zhao~"
