Reborn Technology Scholar

The World Congress of Chinese Mathematicians is a grand event! It is a grand gathering of Chinese mathematicians at home and abroad, and an important channel for exchanges between Chinese mathematics and world mathematics.

Not only the top Chinese mathematicians such as Qin Yuanqing attach great importance to it, but also other Chinese mathematicians attach great importance to it. Even the government attaches great importance to it. The leaders in charge of this part of the work attended this conference.

After all, for the government, promoting exchanges between compatriots at home and abroad has always been a major matter, and it has always spared no effort and made every effort to promote exchanges at home and abroad.

The rejuvenation of China not only relies on the mainland, but also relies on the concerted efforts of the descendants of Yan and Huang at home and abroad to restore the scene of the Han and Tang Dynasties.

Similarly, by asking overseas compatriots to go home and visit more, we can also use the words of overseas compatriots to convey China's great achievements to other overseas scholars, change overseas perceptions of China, and attract other top overseas scholars to conduct academic studies in China.

Visit or even work in China.

The leaders of the World Congress of Chinese Mathematicians made great efforts in those years. The World Congress of Chinese Mathematicians has become stronger and more influential in recent years, not only due to the efforts of mathematicians, but also to the strong support of the Chinese government.

Qin Yuanqing focused his main time and energy on the conference. He not only participated in academic discussions, but also led everyone to visit Tsinghua Garden, Yanda Campus and Shuimu University Shahe Campus. Similarly, during the conference, some scholars asked for advice, Qin Yuanqing was all

It is also Qin Yuanqing's mission to spare no effort to answer questions and cultivate young Chinese mathematicians. Although none of these mathematicians are younger than him, Qin Yuanqing still hopes that another Fields Medal winner will be born. In this case,

It can strengthen the influence of Chinese mathematicians in the world of mathematics.

In the world of mathematics, we do not look at the number of ordinary scholars, nor the number of first-class mathematicians, but the number of top mathematicians, especially the number of top mathematicians.

Qin Yuanqing is relatively optimistic about this, because both Zhang Wei and Deng Tong have a chance to win the Fields Medal.

When you reach a certain level, you no longer limit yourself to the Shuimu Department or the Yan University Department, but look at the entire Chinese community. Otherwise, Qin Yuanqing would have students graduating every year, but Qin Yuanqing did not stay in Shuimu, but supported them to go out as much as possible and do it alone.

knowledge.

The Great Sage of Qin is not just talking.

This conference attracted a large number of mathematics enthusiasts. Although some mathematics enthusiasts could not understand, there were also some mathematics enthusiasts who gained a lot.

On the last day, the 7th World Congress of Chinese Mathematicians came to an end with applause. The next one will not be held until 2019. The winners of the M Mathematics Prize received great exposure and made people aware of these rising stars.

A rising star of mathematician.

With the conclusion of the Seventh World Congress of Chinese Mathematicians, Qin Yuanqing's energy has returned to scientific research work, because the design of the "Phantom" stealth strategic bomber has been completed, and a preliminary design review needs to be held next.

The Aero Engine Research Institute sent the report to its superiors, who immediately attached great importance to it. After all, the Aero Engine Research Institute has continued to make great achievements in recent years, including the Everest aircraft engine, the Gefeng aircraft engine, the heavily armed helicopter aircraft engine, and the heavily armed aircraft engine.

From helicopters to the Y-30 large strategic transport aircraft that has been successfully tested, any result is sensational. This has led to the continuous upgrade of the security measures of the Aero Engine Research Institute, and now there is a platoon to carry out security measures at any time.

Moreover, the scientific research projects of the Aero Engine Research Institute also allowed superiors to see a unique model, that is, a research and development unit first spends money to conduct research and development, and after the research and development is successful, the relevant departments will then buy out the technology payment. This can effectively control risks.

Now the superiors are exploring the feasibility of this method and whether there is any way to apply it to other scientific research institutions.

When the day came for the preliminary review, Qin Yuanqing and others were taken to a secret base with very high security measures. It can be seen that the level of this preliminary review was as high as the previous preliminary review of the Y-30 large strategic transport aircraft project.

Although the H-20 stealth bomber has already undergone test flights, at present, the performance of the H-20 stealth bomber is indeed far ahead of the H-6. However, in terms of bomb load and other performance, the combat range is actually destined to be limited.

Therefore, the ‘Phantom’ stealth strategic bomber design proposed by the Aero Engine Research Institute can undoubtedly make up for the high-level requirements.

The entire preliminary review time is planned to take one week.

As the chief engineer of the Phantom stealth strategic bomber, Qin Yuanqing was the first to introduce the basic parameters and performance of this bomber.

"Dear leaders and experts, the 'Phantom' stealth strategic bomber we are developing is aimed at the American B2 stealth strategic bomber. Its main feature is low detectability, which is commonly known as stealth capability. It can

This allows it to safely pass through a strict air defense system to attack." Qin Yuanqing said: "The stealth of the 'Phantom' stealth strategic bomber is not limited to the radar detection level, but also includes reducing different signals such as infrared, visible light and noise, so that the target can

The possibility of detection and locking is reduced to a minimum."

"According to the design parameters, without refueling in the air, the combat range can reach 12,000 kilometers, and a single in-flight refueling can reach 18,000 kilometers. The air flight time for each mission is generally not less than 10 hours. Once it is put into service, it will basically

It has 'global reach' and 'global destruction' capabilities."

"The 'Phantom' stealth strategic bomber has a length of 21.03 meters, a height of 5.18 meters, a wingspan of 52.43 meters, and a wing sweep angle of 33°. The middle part of the aircraft is raised to accommodate the cockpit, magazine and electronic equipment...

"..." Qin Yuanqing pointed to the aircraft model and introduced: "The installation of lithium-air batteries in these parts can ensure that the aircraft can fly 12,000 kilometers at a speed of 600 kilometers per hour at an altitude of 1,500 meters without fuel after performing a mission!"

After the lithium-air battery was successfully developed, Qin Yuanqing naturally would not let it sit like this, so the spaces in the Phantom stealth bomber that were not suitable for use were transformed to accommodate lithium-air batteries.

Of course, this lithium-air battery cannot support high-altitude and high-speed flight of aircraft, because the oxygen at high altitudes is too thin to ensure that the battery can effectively function, but there is no doubt that it can be used as an aircraft under special circumstances.

After listening to Qin Yuanqing's introduction, leaders and experts were all stunned by the advanced performance of the 'Phantom' stealth strategic bomber. This is not only comparable to the American B2 stealth bomber, but its performance is even better.

But can China build such an advanced strategic bomber?

Leaders and experts couldn't help but feel a little unsure. The h-20 stealth bomber originally did not conduct test flights so quickly. This was mainly due to the international situation and the fact that some key technologies had made breakthroughs in the y-30 strategic transport aircraft and were transplanted to the h-20.

On the stealth bomber, the H-20 stealth bomber has just completed its test flight.

The performance of the 'Phantom' stealth strategic bomber is one level higher than that of the H-20 stealth bomber, and its invitation to technology and craftsmanship is undoubtedly higher.

The United States is able to produce the H-20 stealth bomber, firstly because the United States itself is very powerful in high-precision manufacturing, and secondly because the United States has a global industrial chain that can purchase corresponding materials and accessories from other countries.

But China can't do that, and has to rely on itself in this aspect.

However, they did not raise questions directly. After all, raising questions without basis would only repeat the mistakes of the Y-30 strategic transport aircraft last time.

Who in the industry doesn't know that the Aero Engine Research Institute is different. Other research and development units are polite to leaders and experts. Even if the questions raised are not so professional, the development units will not refute. But the Aero Engine Research Institute is different.

During the review, if you don’t have data to support you, the researchers at the Aero Engine Research Institute can slap the table and question your professional level, questioning whether you can be an expert even with your level.

"Academician Qin, according to your estimation, how much does this 'Phantom' stealth strategic bomber cost?" The leader asked the question he was most concerned about. The performance of the aircraft is very good, but the cost is also very important.

"Leader, based on the current plan, we have calculated that the cost of a 'Phantom' stealth strategic bomber is 9 billion yuan, which is approximately 1.52 billion U.S. dollars!" Qin Yuanqing said.

Today, the exchange rate of the US dollar against the RMB has been fluctuating between 1:5.9 and 1:6.0, and the era of 1:7 has been declared gone forever.

In the past, China relied on a large amount of foreign exchange reserves to act as a shadow currency. At that time, as more and more U.S. dollars were printed, it was not an option for China to follow suit, so there was an appropriate appreciation. Although it was somewhat detrimental to exports, it is still acceptable for now.

When the leader heard this, he couldn't help but feel relieved. Although it was slightly higher than the cost of the H-20 stealth bomber, it was still acceptable. After all, compared with the excellent performance, such a cost was still within the acceptable range.

After all, the cost of building a B2 strategic bomber in the United States is US$2.4 billion, and this was US dollars 20 years ago, and it is estimated to be even higher now.

The reason why the cost of the Phantom stealth strategic bomber is lower than that of the B2 stealth strategic bomber is that it is completely domestically produced. China's labor costs, electricity costs, etc. are several times lower than those of the United States, so the cost will naturally be reduced.

Otherwise, the cost of the Phantom stealth strategic bomber will be similar to that of the B2 stealth strategic bomber, and it will not be much cheaper.

You get what you pay for, and with so much high technology, the cost is naturally high, and this cannot be changed.

Unless large-scale mass production is carried out, it is possible to significantly reduce the cost. However, a big killer like the Phantom stealth strategic bomber, a national artifact, is destined to be impossible to mass-produce. Being able to produce 10 or 20 aircraft is already a lot.

Fantastic.

After all, this is a time of peace, not a time of war, and militancy is undesirable.
