Rebirth of science and technology academic master

Chapter 241: Existence of quality gap?

Qin Yuanqing felt that he was very satisfied with the results he had achieved after resurrecting his life.

Although he had a grudge against Mizuki at first, he felt that this was just an incubator for overseas Yingjiang, specializing in providing talents for overseas Yingjiang. But later he still chose Mizuki, where he felt that he had succeeded.

First of all, the military training model has been changed and the patriotic education and patriotic sentiments of Shuimu people have been strengthened. It should no longer become a talent training base for overseas Yingjiang. Even if they go to study abroad, most people should choose to return to China.

Secondly, it changed the positioning of Shuimu University. Originally, Shuimu University was positioned as a university of science and technology. However, for some reason, this major was added, and that major was added. Inexplicably, it was almost the same as a comprehensive university.

If Shuimu University was a comprehensive university, why did the country need to split and reorganize major universities in the first place.

Therefore, with the efforts of Qin Yuanqing, Shuimu University has repositioned itself as a polytechnic university and a research-oriented university. It is no longer employment-oriented. In the future, it will not talk about employment in the university, but is positioned to cultivate talents who are the pillars of the country!

Therefore, the Academy of Fine Arts and other colleges will gradually separate from Shuimu in the next two years.

To be honest, Qin Yuanqing was really shocked by the incident at Shuimu Academy in his last life. It completely subverted his understanding of Shuimu.

After the school meeting, Qin Yuanqing felt much more relaxed. He spent time with his wife and children every day, and usually worked at the research institute. Unless necessary, Qin Yuanqing basically did not leave the capital. Qin Yuanqing declined many invitations to meetings.

Perhaps the birth of the child brought him good luck, and Qin Yuanqing achieved considerable results in Yang Mills' theory.

But as we gradually entered the deep water area, the difficulty began to increase.

For example, he is thinking about a problem right now. According to the viewpoints of quantum field theory and quantum chromodynamics, the four fundamental forces and traditional particles can be unified. For example, at different locations in space and time, the components of the electric field can be constructed into non-commutative operators. When constructing the Hilbert space in which these operators act, traditional particles, such as electrons, can be reinterpreted as Dirac Quantization of fields.

In this way, the difference between fields and particles disappears.

Can we use a concise mathematical form, like the Weinberg-Salam-Glashow electroweak unified theory, which describes the electromagnetic force and the weak interaction force in a unified way, to describe the strong interaction, and combine it with the electromagnetic force? Reach unity?

Yes, Qin Yuanqing studied and studied, and discovered a situation, that is, when Yang Mills' theory is solved, the unification of mechanics, that is, the unification of physics, has also been solved!

It's just not easy to do this.

For example, the strong interaction force is different from the weak interaction force, and there is a very typical problem. . . . . .

"How to explain the existence of the mass gap in mathematical language?" This is the big mountain currently blocking Qin Yuanqing's progress.

Yang and Mills discovered that quantum physics revealed a remarkable relationship between elementary particle physics and the mathematics of geometric objects. Predictions based on the Yang-Mills equation have been confirmed in high-energy experiments performed at laboratories around the world: Brockhaven, Stanford, CERN, and Tsukuba. Still, their mathematically rigorous equations, which both describe heavy particles, have no known solution. In particular, the "mass gap" hypothesis, recognized by most physicists and used in their explanation of the invisibility of "quarks", has never been confirmed to a mathematically satisfactory degree. Progress on this problem requires the introduction of fundamentally new ideas, both in physics and mathematics.

It can be said that Qin Yuanqing has now arrived in the deep water area. In this deep water area, how to use mathematical language to explain the existence of the mass gap has become an extremely important key.

Only by overcoming this difficulty can we continue to climb the peak of Yang Mills, otherwise it will be difficult to move forward. There are no shortcuts in mathematical research like this. The thinking must be tight and flawless. Otherwise, if there are fatal flaws, it will be useless work.

On July 25, Qin Yuanqing had to stop his thinking, bid farewell to his wife for the time being, and went to the aircraft engine, because the Everest aircraft engine ushered in a milestone, running for a full 7,000 hours, which can be said to be a milestone. The significance is extraordinary for China, because the life of the AL-41 turbofan engine introduced by China to Russia is less than 5,000 hours. Now the life of the Everest aviation engine has reached the 7,000-hour mark, which has far exceeded the Russian AL-41 Turbofan engine.

Although the Russian AL-41 turbofan engine has a maximum thrust of 12 tons and an afterburning thrust of not less than 17.8 tons, which is higher in terms of afterburning thrust.

But for aeroengines, thrust is important, and the design life of the aeroengine is also important, because it involves the cost of use.

And what is very important is that China controls the entire technology of the Everest aviation engine, while Russia’s AL-41 turbofan engine needs to be imported, and it cannot be obtained by signing a contract. Instead, it needs to wait, maybe several times. It takes years to get it.

In the war years, this kind of thing would be life-threatening, and it would be easy to get stuck.

Therefore, the success of Everest aviation engine can be said to be attracting attention in the industry. Compared with the Taihang engine and the Kunlun engine, which constantly have problems, the Everest aircraft engine is simply too good. Whether it is the experimental test here or the flight verification and evaluation over there in Sichuan, everything went smoothly.

As for the problems in Sichuan and Sichuan, the engines have not had problems so far. The problems are in the stealth design, avionics system, anti-G suit, etc. After all, in the empty state, the speed of the aircraft even exceeds the speed of the missile. This The requirements for human body protection are very high. Even when the aircraft reaches Mach 2, people will feel dizzy, so the relevant design teams are making optimization improvements.

After the engine was tested for 7,000 hours, Qin Yuanqing and the inspection team began to inspect the entire aeroengine. Although some places began to deform, it did not affect its continued use.

Moreover, Qin Yuanqing compared the experimental data during this period one by one. It was slightly better than the F119 aero engine data released by the United States, but it was similar.

After staying at Aviation Engine for two days, Qin Yuanqing made another trip to Chengdu, because the flight experiment with fighter jets here had also reached the 1,000-hour mark, and Qin Yuanqing needed to know the relevant situation.

Aviation engines must eventually be mounted on fighter aircraft and undergo actual testing before their performance can be finally determined.

And there is another important topic this time, which is to study whether the J20B fighter jet can participate in the 10th Zhuhai Air Show next year, so as to deter some people with ulterior motives.

"Academician Qin, at present, the overall performance of the aero engine is very stable. It is a very mature aero engine. It brings powerful power to fighter aircraft. It is a strong heart. Our Chinese Air Force no longer has to worry about heart attacks. !" Chief Master Yang accompanied him and seemed to be in a good mood!

The most important thing about a fighter plane is the aeroengine. This is the heart of the fighter plane. Once there is a problem with the heart, it will be useless no matter how well you do in other aspects.

China has developed to this day and has achieved breakthroughs in many technologies, such as avionics systems, radars, and air-to-air missiles, but engines have always been the most troublesome.

But now, the excellent performance of the Everest aircraft engine makes Commander Yang think that the problem of heart disease in fighter aircraft has been solved.

"The next test will be a full-load state test to see the various indicators of the full-load state!" Chief Engineer Yang introduced.

In fighter aircraft testing, a very important indicator is the combat radius. If a fighter aircraft has a small combat radius, it will have no combat effectiveness.

The S-27 has a combat radius of 1,300 kilometers and the J10 has a combat radius of 1,250 kilometers!

The combat radius of the J20B will only be known after continuous testing.

But there is no doubt that the Everest aircraft engine is an excellent engine. This is already recognized by those who participated in the test.

"Now the Aero Engine Research Institute is developing an engine based on the Everest aircraft engine to benchmark the American F135, reducing the number of spare parts and lowering the cost!" Qin Yuanqing also talked about the ongoing research and development of the Aero Engine Research Institute Task.

"This is a good thing. Then we will be like the United States, having two fourth-generation fighters with excellent performance!" Commander Yang said with a smile.

During the meeting, various design-related units participated. They analyzed the causes of various problems that occurred during this period and proposed improvement measures. Everyone patted their chests and said that there will be no problem at the Zhuhai Air Show next year, and they will definitely make the J20B the best. Status to attend.

Qin Yuanqing stayed in Chengdu for three days before leaving. He specifically visited the production of aircraft. This is an important production unit of Chinese fighter planes. A fighter plane is produced here almost every day. That kind of production efficiency is absolutely amazing.

Of course, at this stage including the next period of time, the main force of the Chinese Air Force is still the J10 and various improved models.

The service life of a fighter aircraft is very long. Although the fourth-generation aircraft has been released, the third-generation aircraft are still the mainstream and the main force of the air forces of various countries, and the United States is no exception.

Even in this world, there are only a few countries that can produce third-generation aircraft, and the remaining 99% of countries do not have it.

Just like in China now, Ba Ye's shadow can still be seen, and it is estimated that there is still a long way to go before he completely retires from active service.

Qin Yuanqing remembered that he once flew to Wuyishan. When he was at Wuyishan Airport, he saw more than a dozen Eight Masters. The rows were unbelievable. At that time, the fourth generation aircraft had begun to form an army, and the Eight Masters were still in service. .

Qin Yuanqing also thought that this year's military expenditure has increased a lot, and it is estimated that the Air Force is also accelerating its upgrading and transformation. Next year, the J-10 is expected to be put into service in groups, and it will truly become the middle force of the Air Force until the fourth-generation aircraft is actually mass-produced. Serve, and this time will take several years.
