Chapter 339 'Phantom' Stealth Strategic Bomber Preliminary Review Meeting

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 the communication between Chinese mathematics and world mathematics.

Not only the top Chinese mathematicians such as Qin Yuanqing, not only other Chinese mathematicians, but also 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 event, and it has always spared no effort to promote internal and external exchanges.

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

In the same way, letting overseas compatriots go home to see more can also use the mouth of overseas compatriots to pass on the great achievements of China 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 Huaxia.

The leaders of the World Chinese Mathematicians Conference back then made great efforts. The World Chinese Mathematicians Conference has become stronger and more influential in recent years, not only because of the efforts of mathematicians, but also because of the strong support of the Chinese government.

Qin Yuanqing devoted his time and energy to the conference, not only participating in academic discussions, but also leading everyone to visit Tsinghua Park, Yanda Campus and Shuimu University Shahe Campus.Similarly, when some scholars asked for advice during the conference, Qin Yuanqing spared no effort to answer. It is also a major mission of Qin Yuanqing to train young Chinese mathematicians. The birth of a Fields Medal winner will also strengthen the influence of Chinese mathematicians in the world mathematics community.

The world's mathematics community does not look at ordinary scholars or the number of first-class mathematicians, but the number of top mathematicians, especially the number of top mathematicians.

Qin Yuanqing is quite 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 will no longer limit whether the Shuimu department or the Yanda department, but look at the entire Chinese community. Otherwise, Qin Yuanqing will have students graduating every year, but Qin Yuanqing will not stay in Shuimu, but support 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, some mathematics enthusiasts gained a lot.

On the last day, the 2019th World Congress of Chinese Mathematicians came to an end amidst applause, and the next session will be held in [-]. The most popular news these days are several winners of the ICCM Mathematics Award, who received a lot of attention. The degree of exposure also makes people aware of these rising mathematician stars.

With the conclusion of the [-]th World Congress of Chinese Mathematicians, Qin Yuanqing also returned to scientific research work, because the design of the 'Phantom' stealth strategic bomber has been completed, and the preliminary design review needs to be held next.

The Aero-Engine Research Institute sent the report to the superior, and the superior immediately attached great importance to it. After all, the Aero-Engine Research Institute has continuously made great achievements in recent years, first, the Everest Aero-Engine, the Gefeng Aero-Engine, the Heavy-Armed Helicopter Aero-Engine, the Heavy Armed From the helicopter to the Y-30 large-scale strategic transport aircraft that has been tested successfully, any achievement is a sensation. This has continuously upgraded the security measures of the Aero Engine Research Institute, and now there is a platoon for security measures at any time.

Moreover, the scientific research projects of the Aviation Engine Research Institute also let the superiors see a unique model, that is, some research and development units pay for research and development first, and then the relevant departments buy out the technical payment after the research and development is successful. This can effectively control risks. Now the superiors are discussing the feasibility of this method, and whether there is a way to apply it to other scientific research institutions.

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

Although the H-20 stealth bomber has been tested, but at present, the performance of the H-20 stealth bomber is indeed a lot ahead of the H-6, but in terms of bomb load and other performance, it is actually destined to have a limited combat range.

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

The entire preliminary review time is planned to be 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.

"Leaders and experts, the 'Phantom' stealth strategic bomber we are developing is aimed at the B2 stealth strategic bomber of the United States. Its main feature is low detectability, which is commonly known as stealth capability. Let it safely pass through the tight air defense system to attack." Qin Yuanqing said: "The stealth of the 'Phantom' stealth strategic bomber is not limited to the level of radar detection, but also includes reducing infrared, visible light and noise. The possibility of detection and lock-in is minimized."

"According to the design parameters, without refueling in the air, the combat range can reach 1.2 kilometers, and one refueling in the air can reach 1.8 kilometers. The flight time of each mission is generally not less than 10 hours. Once it is in service, 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 plane is raised to accommodate the cockpit, magazines and electronic equipment." Qin Yuanqing pointed at the plane The model introduced: "The installation of lithium-air batteries in these parts can ensure that the aircraft can fly 1500 kilometers at a speed of 600 kilometers per hour at an altitude of 1.2 meters without fuel after performing missions!"

The lithium-air battery was successfully developed, and Qin Yuanqing naturally wouldn't let it just sit there. The unsuitable space of the "Phantom" stealth bomber was transformed into a lithium-air battery.

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

After hearing Qin Yuanqing's introduction, all the leaders and experts were stunned by the advanced performance of the 'Phantom' stealth strategic bomber.

But can China manufacture such an advanced strategic bomber?
The leaders and experts couldn’t help but feel a little lack of confidence. The H-20 stealth bomber did not conduct a test flight so quickly. The main reason was that the international situation forced it, and some key technologies 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 the test flight.

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

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

But Huaxia can't do it, it has to rely on itself.

However, they did not directly raise doubts. After all, raising doubts 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 R&D units are polite to leaders and experts. Even if the questions raised are not so professional, the R&D units will not refute them.But the Aero-Engine Research Institute is different. If you don’t have data to support it during the review, the researchers of the Aero-Engine Research Institute can slap the table and question your professional level. If you question your level, you can also be an expert.

"Academician Qin, according to your estimates, what is the cost of this 'Phantom' stealth strategic bomber?" 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, according to the current plan, we calculated that the cost of a 'Phantom' stealth strategic bomber is 90 billion yuan, or about 15.2 billion U.S. dollars!" Qin Yuanqing said.

如今美元对人民币汇率一直在1:5.9~1:6.0之间波动，1:7时代宣告一去不复返。

In the past, relying on a large amount of foreign exchange reserves, Huaxia acted as a shadow currency. At that time, as more and more US dollars were printed, it was not an option for Huaxia to follow suit, so there was a proper appreciation. Although it was not good for exports, it was still acceptable.

The leader couldn't help but breathe a sigh of relief when he heard it. Although the cost of the H-20 stealth bomber is slightly higher, it is still acceptable. After all, compared with the excellent performance, such a cost is still within the acceptable range.

After all, the cost of a B2 strategic bomber in the United States is as high as 24 billion U.S. dollars, and this is the U.S. dollar 20 years ago, and it is estimated to be even higher now.

The reason why the cost of the "Phantom" stealth strategic bomber is still lower than that of the B2 stealth strategic bomber is that it is completely domestically produced, and China's labor costs and electricity costs are several times lower than those of the United States, so the natural cost will also 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 many high technologies involved, the cost is naturally high, which cannot be changed.

Unless it is mass-produced, it is possible to significantly reduce the cost, but the "Phantom" stealth strategic bomber is destined to be impossible to mass-produce, and it is already very difficult to produce 10 or 20 aircraft. Fantastic.

After all, this is an age of peace, not an age of war, and militarism is out of the question.
