Rebirth of science and technology academic master

Chapter 273: Re-Winning the Philippine Award

The 'Gefeng' aircraft engine is developed based on the core machine and main structure of the Everest aircraft engine. The maximum thrust exceeds 18 tons. In order to be used as a carrier-based aircraft, it must be able to take off and land vertically, so the 'Gefeng' aircraft engine It is also possible to add a downwardly bent three-bearing rotating nozzle, but this nozzle is only used for vertical takeoff and landing, which can greatly shorten the distance between takeoff and landing.

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

It can be said that the ‘Ge Feng’ aero engine is a derivative of the Everest engine. In order to increase thrust, the air flow and bypass ratio of the engine are increased, and the operating temperature of the engine is increased. In order to obtain short 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 welded integral blisk and detuning technology, while maintaining the advanced pressure ratio, high efficiency, large surge margin and light weight of the original fan. The cross-sectional area of ​​the fan is increased 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 aeroengine, Qin Yuanqing did not cheat. He only gave occasional advice, and the rest was done by the R\u0026D staff.

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

Once the fighter is installed, it can be matched with the J20B to form a high-low configuration. The unit price of a fighter like the J20B is still too expensive for China, with a cost of nearly 100 million US dollars. Even though China's economy is developing rapidly and military expenditures are increasing every year, there is no way. Equipped with a large number of J20Bs, a low-end version of the fourth-generation fighter is needed. According to Qin Yuanqing's estimation, the cost of the low-end version will not even cost 50 million US dollars, which is much cheaper in comparison, with the price reduced by half.

For example, this low-end version of the fourth-generation aircraft only requires one Gefeng aeroengine, which more than doubles the price of the aeroengine.

Qin Yuanqing went to the Aviation Development Group and looked at the Ge Feng engine that had been manufactured. Since the Everest engine was being produced at the same time, many parts were shared, so it was much faster to produce the Ge Feng engine prototype.

To be honest, the production speed of Everest aviation engines is not very fast. The annual output is now only 25 units. This means that at most 10 J20Bs are in service a year. The speed is far slower than that of the F22. The F22 production line takes a total of 8 years. The output is 187 aircraft, with an average annual output of 23 aircraft and a maximum annual output of 30 aircraft when the horsepower is fully turned on.

As the test begins, as soon as the switch is turned on, the engine roars, a sound full of power that makes people's blood boil.

The start-up test went smoothly, and nothing went wrong at the beginning. Qin Yuanqing was relieved. For this test team, the Aero 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 fighters. Intensive flight testing last year showed excellent performance. The avionics system, missile launch system, etc. were completely finalized after several optimizations. The four produced The fighter jets 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. Then the Air Force pilots cut the big red flowers after taking an oath. Then the leaders officially announced the delivery for use, and the pilots finally drove the plane back to the air force base.

Qin Yuanqing watched the planes take off one by one, like eagles and dragons, and his heart was filled with enthusiasm. China's fighter planes entered service earlier than in the previous generation, and they had advanced fighter planes to protect China's airspace.

Of course, after the aircraft is delivered, there will still be a period of time before it can form combat effectiveness. This period includes the Air Force's exploration, aerial refueling, etc. Only after training and running-in can the fighter jets form combat effectiveness.

As Shuimu freshmen started school and had 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 General Qin Yuanqing. This is also the first time Qin Yuanqing has presided over military training as the executive vice principal.

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

As a big figure in the international mathematics community, Qin Yuanqing also has the responsibility to maintain the popularity and influence of this conference, so he naturally needs to attend.

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

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

Yes, this is already the consensus of the mathematical community!

When Qin Yuanqing solved the Millennium Problem, even the Clay Research Institute gave Qin Yuanqing a reward of one million US dollars, which means that this year's Fields Medal winner has lost all 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 community and was an out-and-out newcomer in the international mathematics community.

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 mathematics world.

At his first participation in the World Congress of Mathematicians, Qin Yuanqing won his first Fields Medal, announcing his promotion to a mathematics boss.

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 is indispensable in the world's top ten scientific and technological achievements. Last year, Goldbach's conjecture was proved to be directly at the top of the list. This year, if nothing else, he will not be at the top. It can't be out of Qin Yuanqing's palm.

Now, Qin Yuanqing's status in the mathematics community is very high, and Wiles, Faltings, etc. are 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. It has become an important force that cannot be ignored by international mathematics forces, and this force is still increasing rapidly.

In the past, world-class mathematicians were unwilling to give lectures at famous Chinese universities. Even if famous schools such as Shuimu University and Yanda University offered very objective fees, those world-class mathematicians were not willing to go because there was contempt, arrogance and look down on them in their hearts. Chinese Mathematics.

But now more and more world-class mathematicians are giving lectures at famous Chinese universities and even becoming chair professors.

This is a manifestation of increased influence.

On August 13, 2014, more than 5,000 top mathematical geniuses from around 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 Olympics in mathematics. From 1897 to the present, except for two world wars, there has been no interruption.

As an international conference that provides a space for mathematicians around the world 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 particularly special significance. Because of the Millennium Problem, the conference has attracted worldwide attention since its opening.

9:00 a.m. sharp.

Scholars in the venue took their seats one after another, and the 27th 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 new and old friends who came to attend the conference, and at the same time announced the opening of this mathematics conference.

After the opening ceremony, there is the awards ceremony.

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

The Gauss Prize winner, the Chen Shengshen Prize, the Riva Rati Prize and other awards were awarded successively. Mathematicians cried with joy. After all, being able to win the award is in itself recognized by the international mathematics community.

Finally, as the focus of the award ceremony and the highlight of 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 produced by people under the age of 40, and the Fields Medal is the highest honor that mathematicians under the age of 40 can achieve, and is known as the Nobel Prize in mathematics.

Although medals do not determine whether a scholar is great, the scholars recognized by this medal are all top-notch scholars who have influenced the development of the subject of mathematics and are the mainstay of the academic community.

During the announcement of this list.

Many people held their breath unconsciously and stared at the stage with burning eyes.

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

The only exception was Qin Yuanqing. Qin Yuanqing was very calm and not nervous at all. He has already won the Fields Medal once, but he doesn't really care whether he wins it this time or not.

Only if you are particularly concerned will you be nervous at this moment.

The President of the International Mathematical Union may have felt the heat of the audience's attention. After clearing his throat, he read out the award speech for the winner in a solemn and steady voice: "He is a talented young man who has spanned many fields. He has made great achievements in the fields of mathematics, number theory, algebraic geometry, algebra, geometry, topology, mathematical analysis, etc. He has made great contributions to the development of mathematics!"

"The winner - Qin Yuanqing!"

When the winners were announced, the atmosphere in the venue was instantly ignited, and everyone gave warm applause.

It’s not big news that Qin Yuanqing won the Fields Medal! Not awarding the Fields Medal to Qin Yuanqing would be big news!

And with Qin Yuanqing winning the Fields Medal, it also means that a new record has been set for the Fields Medal, that is, he is the first person to win the Fields Medal for consecutive years!

This is a very great record. It is already difficult to win the Fields Medal once, let alone win the Fields Medal twice, let alone win it consecutively!

Everyone gave applause to Qin Yuanqing, a giant who has continuously made great achievements in mathematics in the past four years and promoted the advancement of mathematics with one person's power. Others have joined forces to form a school and a force, but Qin Yuanqing alone is the leader. One school and one force.

Thank you to the alliance leader ‘Seventeen Years Book Spirit’, the second alliance leader in this book! At the same time, thank you all for your continued support and companionship!

According to the previous promise, a leader will update 10 chapters, and today we will update 10 chapters!
