Chapter 272 Won the Philippine Award (adding 17 more for the leader of the "1 Years of Shuling")

Chapter 273 Winning the Philippine Award

The 'Gefeng' aero-engine is developed based on the core engine and main structure of the Everest aero-engine. It is also possible to add a downwardly bent three-bearing rotating nozzle, but this nozzle is only used in vertical take-off and landing occasions, which can greatly shorten the take-off and landing distance.

Of course, you can also not use this design according to the situation.

It can be said that the 'Gefeng' aero engine is a derivative of the Everest engine. In order to increase the thrust, the air flow and bypass ratio of the engine have been increased, and the operating temperature of the engine has been increased.In order to obtain short-distance take-off and vertical landing capabilities, the vertical take-off and landing type adds a novel lift fan, three-bearing rotating nozzle, and roll control nozzle.Its 3-stage fan adopts ultra-medium aspect ratio, forward-swept blades, linear friction welding integral blade disc and detuning technology, while maintaining the high pressure ratio, high efficiency, large surge margin and light weight of the original fan, Increase the cross-sectional area of ​​the fan by 10%-20%. The 6-stage compressor is basically the same as that of the Everest engine.

In the research and development of Ge Feng's aero-engine, Qin Yuanqing did not cheat, that is, he gave pointers occasionally, and the rest were made by the research and development personnel.

After such a long period of digestion and absorption, it was successfully fiddled with. According to the current prototype, the cost of construction has been reduced a lot.

Once the fighter is installed, it can be matched with the J20B. The unit price of a fighter like the J20B is still too expensive for China, and the cost is nearly 20 million US dollars. Even if China's economy develops rapidly, military expenditures are also increasing every year, but there is no way. Equipped with a large number of J5000Bs, a low-profile version of the fourth-generation fighter is needed. According to Qin Yuanqing's estimation, the cost of the low-profile version will not even cost [-] million U.S. dollars, which will be much cheaper in comparison, and the price will be reduced by half.

For example, this low-profile version of the fourth-generation aircraft only needs one Gefeng aero engine, which more than doubles the price of the aero engine.

Qin Yuanqing went to the Aviation Development Group and looked at the Gefeng engine that had already been manufactured. Because the Everest engine was being produced at the same time, many parts were shared, so the production of the Gefeng engine prototype was much faster.

To be honest, the production speed of Everest aero-engines is not fast, and the annual output is only 25 units, which means that there are at most 10 J20Bs in service a year, and the speed is far behind the F22. The production line of the F22 takes 8 years to complete. The output is 187, the average annual output is 23, and the maximum annual output reaches 30 when the horsepower is fully turned on.

As the test began, as soon as the switch was turned on, the engine roared. The sound full of power made people's blood boil.

The start-up test went smoothly, and there were no moths at the beginning, so Qin Yuanqing was relieved. For this test group, the Aviation Engine Research Institute sent 20 researchers to solve various problems encountered during the test.

After attending the ceremony, Qin Yuanqing went to Bashu again to participate in the delivery ceremony of the first batch of J20B fighter jets. Last year, they performed intensive flight tests and performed well. The avionics system and missile launch system were optimized and finalized. The aircraft will be delivered to the Air Force.

The delivery ceremony of the fighter plane was very ceremonial. The fighter plane was hung with big red flowers. After the air force pilot took the oath, he cut off the big red flower. Then the leader officially announced the delivery, and the pilot finally drove the plane back to the air force base.

Qin Yuanqing watched the planes take off one by one, like eagles, like dragons, and his heart was full of enthusiasm. Huaxia entered service earlier than his previous life, and had advanced fighter jets to guard Huaxia's airspace.

Of course, after the delivery of the aircraft, there is still a period of time before the formation of combat effectiveness. This period includes air force exploration, aerial refueling, etc. After training and running-in, fighter jets can form combat effectiveness.

With Shuimu's new school report and military training, Qin Yuanqing bid farewell to his parents, left his hometown with his wife and children, and returned to the capital.

This year's military training is still in charge of Mr. Qin Yuanqing, and this is the first time that Qin Yuanqing presides over military training as the executive vice principal.

However, Qin Yuanqing did not appear at the freshman military training meeting on the first day. Qin Yuanqing went to Koguryo to participate in the International Mathematical Union's "2014 World Congress of Mathematicians".

As a bigwig in the international mathematics community, Qin Yuanqing is also responsible for maintaining the popularity and influence of this conference, so he naturally needs to attend.

What's more, he received an invitation letter from the International Union of Mathematicians to give a one-hour report at the Congress of Mathematicians very early.

In the past four years, his achievements far surpassed those of other mathematicians. Everyone knows that Qin Yuanqing will receive his second Fields Medal in this conference of mathematicians.

Yes, this is already the consensus of the mathematics community!
When Qin Yuanqing solved the millennium problem, even the Clay Research Institute gave Qin Yuanqing a reward of 100 million US dollars, which meant that this year's Fields Medal winner had lost suspense.

In 2010, Qin Yuanqing participated in the Mathematicians Conference for the first time. Although he had made great achievements at that time, he had just become famous in the international mathematics circle, and he was an out-and-out newcomer in the international mathematics circle.

Even at that time, most mathematicians believed that the Fields Medal would not be awarded to a newcomer like Qin Yuanqing, because he was too young and had just entered the circle of mathematics.

And for the first time to participate in the World Congress of Mathematicians, Qin Yuanqing won the first Fields Medal in his life, announcing that he was promoted to a mathematician.

In the past four years, relying on his own mathematical achievements, Qin Yuanqing's influence has been increasing day by day. Every year, Qin Yuanqing's figure is indispensable to the world's top ten scientific and technological achievements. Last year, Goldbach's conjecture proved to be directly on the top of the list. If nothing happens this year, he will also escape from the top of the list. Out of Qin Yuanqing's palm.

Up to now, Qin Yuanqing's status in the mathematics world is very high, and Wiles, Faltings, etc. are all inferior. Some mathematicians have privately called Qin Yuanqing the Pope of Mathematics.

Moreover, under the influence of Qin Yuanqing, the power of the Chinese mathematics community has continued to increase, and it has become an important force that cannot be ignored by the international mathematics forces, and this power is still increasing rapidly.

In the past, world-class mathematicians were unwilling to give lectures in famous Chinese universities, even if famous schools such as Shuimu and Yanda offered very reasonable fees, but those world-class mathematicians were unwilling to go, because there was contempt and arrogance in their hearts, and they looked down on them. Huaxia Mathematics.

But now more and more world-class mathematicians are giving lectures in famous Chinese schools, and even a lecture professor.

This is a manifestation of increased influence.

On August 2014, 8, more than 13 top mathematics geniuses from all over the world gathered at the COEX Convention and Exhibition Center in Seoul, Goguryeo, and the venue was crowded.

As the largest and most important conference in the international mathematics community, the International Congress of Mathematicians is known as the Olympic of mathematics.From 1897 to the present, except for two world wars, it has never been interrupted.

As an international conference that provides mathematicians around the world with a space to communicate, discuss academic issues, meet old friends, and make new friends, each conference plays a pivotal role in the history of mathematics.

This year's conference is of special significance, because of the millennium problem, this conference has attracted worldwide attention from the very beginning.

9:00 sharp in the morning.

Scholars in the venue were seated one after another, and the No.20 Seventh International Congress of Mathematicians officially kicked off.

The chairman of the Organizing Committee of the conference and the chairman of the International Mathematical Union delivered opening speeches on the stage respectively, thanking the local organizers of the conference, thanking the old and new friends who came to the conference, and announcing the opening of this Mathematical Conference.

After the opening ceremony, it will be the awards ceremony.

At the moment of entering this link, the atmosphere of the meeting was immediately pushed to a climax.

Gauss Prize winners, Chern Prizes, Riva Rathi Prizes and other awards were presented one after another, and each mathematician wept with joy. After all, winning an award is itself recognized by the international mathematics community.

Finally, as the focus of the awards ceremony and the opening ceremony of the entire International Congress of Mathematicians, the president of the International Mathematical Union will announce the winners of the Fields Medal.

The vast majority of mathematical achievements are born under the age of 40, and the Fields Medal is the highest honor that mathematicians under the age of 40 can obtain, known as the Nobel Prize in mathematics.

Although the medal does not determine whether a scholar is great or not, the scholars who have been recognized by this medal are all super-class scholars who have influenced the development of mathematics as a discipline and the mainstay of the academic world.

Between the publication of this list.

Many people held their breath unconsciously, staring at the stage with fiery eyes.

Especially those candidates who are expected to win the Philippine Award.

The only exception was Qin Yuanqing, who was very calm and not nervous at all.He had already won the Fields Medal once, and he didn't really care if he won it this time.

Only when you care about it will you be nervous at this moment.

The president of the International Mathematical Union may have sensed the intense gaze from the audience. After clearing his throat, he read out the winner's award speech in a solemn and steady voice: "He is a talented young man who spans many He has made great achievements in the field of mathematics, such as number theory, algebraic geometry, algebra, geometry, topology, mathematical analysis, etc., and he has made great contributions to the development of mathematics!"

"The winner - Qin Yuanqing!"

The moment the winners were announced, the atmosphere of the venue was instantly ignited, and everyone gave warm applause.

It is not big news that Qin Yuanqing won the Fields Medal!It would be big news not to award Fields to Qin Yuanqing!
And with Qin Yuanqing winning the Fields Medal, it also means that a new record has been born for the Fields Medal, that is, the first person to win the Fields Medal consecutively!
This is a very great record. It is already very difficult to win the Fields Medal once, not to mention winning the Fields Medal twice, let alone consecutively!
Everyone gave Qin Yuanqing applause to this giant who has made great achievements in mathematics in the past four years and promoted the advancement of mathematics by himself. One faction, one force.

　Thank you leader '17 Years Book Spirit', the second leader of this book!At the same time, thank you for your continued support and company!
　　According to the previous promise, a lord will add 10 chapters, and ten chapters will be added today!
