Chapter 1001 Beijing Academy of Science and Technology

Zhao Zhongyao listened to Liu Changyun's words, then smiled again and said: "Minister Liu, I'm sorry, I'm afraid I can't pick out the talents I need in our General Armament Department." ”

Hearing Zhao Zhongyao say this, Liu Changyun said with some puzzlement: "Oh, the talent you need can't be picked out in our General Armament Department, so you have to go there to pick it." ”

"You should go to the capital. Only by going to the capital can we pick out some cutting-edge talents. Zhao Zhongyao knows that Beijing is the political, economic and cultural center of the country. It is also the place with the highest concentration of talents in the country, and only when you go to the capital can you pick the talents you want.

After listening to Zhao Zhongyao's words, Liu Changyun thought about it for a while and felt that what he said also made sense. Although there are some talents in their General Armament Department, they are not the most cutting-edge talents. Only by going to the capital can we find the most cutting-edge talents.

"Well, Zhongyao, what you said makes sense, it seems that we are going to the capital again. Liu Changyun knew that if he wanted to find some cutting-edge talents, he could only go to the capital.

"Zhongyao, if that's the case, then I'll accompany you on a trip! Minister Liu is busy with work, so he doesn't need to run errands anymore. Liu Tianming felt that it was better for him to do it with Zhao Zhongyao. Don't bother Liu Changyun anymore.

"Okay, then let the two of you do it! You go first, and if you have any difficulties, call me, and I will help you out." ”

Liu Changyun also knows that it is not easy to find some cutting-edge talents. In the process of searching, there will definitely be a lot of difficulties. Although he didn't go to the capital, he could also help Zhao Zhongyao and Liu Tianming by phone.

"Okay, that's it, we'll leave tomorrow. Zhao Zhongyao knew that his time was tight, and if he wanted to do this, he had to do it quickly.

"Okay, tomorrow you will take a plane to the capital! I will reimburse you for all the expenses on the road when you come back." Liu Changyun looked at Zhao Zhongyao and Liu Tianming again and said.

"Okay, then let's go back first. Zhao Zhongyao said again.

In this way, the next day, Zhao Zhongyao and Liu Tianming took a plane to the capital again.

The two of them came to the 'Beijing Science and Technology Institute' first.

This 'Beijing Science and Technology Institute' is a place to cultivate top talents in the country. The researchers are the best college students carefully selected from the country's first-class universities. They all have the most cutting-edge expertise in various industries.

Zhao Zhongyao knew that in order to develop a new type of fighter, the first thing to do was to develop the engine of this new type of fighter. The engine can be said to be the core component of any vehicle, and it is also the most high-tech component.

Aircraft engines are different from ordinary engines.

Most of the family cars on the market use piston engines.

Airplanes are different, there are piston engines, and there are gas turbines. Modern mainstream commercial airliners use turbofan engines, and many small private jets, training aircraft or agricultural aircraft still use piston machines.

If you talk about piston engines, the basic principle is not much different, simply put, it is the four strokes of air intake compression and work exhaust in junior high school physics. Due to the different shapes of airplanes and cars, there are some differences in the arrangement of engine cylinders, and most of the planes are arranged in a star shape or horizontally. There are more in-line ones on the car, and the more advanced ones have a V-shaped arrangement.

However, due to the large number of cars, all countries have relatively stringent emission requirements, and the market competition is also huge, so major car manufacturers are constantly using new technologies to improve product competitiveness. What is the direct injection in the cylinder, double injection, layered combustion, the introduction of Atkinson thermal cycle, variable valve timing, variable valve lift, harmonic interference intake, adjust the valve overlap angle, high-speed combustion and so on. On the other hand, the restrictions on piston machines by various civil aviation agencies are not as strict as those for automobiles, and the market competition is not as fierce as for automobiles. Personally, I feel that the application of new technologies in automobile engines is far more interesting than the piston machines in airplanes.

But whether it is a car engine or an aircraft engine, it is a heat engine.

The so-called heat engine is the conversion of the thermodynamic energy of a substance into mechanical energy. The fundamental difference between an automobile engine and an aero engine is the difference in the process of converting thermodynamic energy into mechanical energy. In order to understand the essential difference between the two, we must first understand the fundamental principle of heat engine energy conversion.

The most fundamental source of energy for the heat engine is the energy of the fuel, and the mission of the heat engine is to use it. For a long time, human beings have only used these energies to "produce heat", such as burning coal to cook food, building stoves in winter, friction to generate heat, and so on. But by the time of the Industrial Revolution, Britain's forests were becoming increasingly scarce, the demand for coal was increasing, and the mines were becoming more and more deep. Pumping water from mines is becoming more and more difficult, and traditional manual water lifting is becoming more and more uneconomical. This urgent need led to the development of a hydro-pumping machine. Put a small amount of water at the bottom of the cylinder, heat the cylinder, vaporize, expand internally, drive the piston to move up, and then remove the heating source, the steam in the cylinder condenses, forming a vacuum, the piston falls under atmospheric pressure, and the falling process provides power for pumping. This was the first forming heat engine.

Although the professional scientific and technological talents in Huaguo are not very good, there are still some such high-level talents in the place where this talent gathers in Beijing.

Zhao Zhongyao and Liu Tianming came to the most famous university of science and technology in Beijing. The two of them are here to pick some excellent talents. Naturally, we have to find the principal of this school first.

Led by a student, Zhao Zhongyao and Liu Tianming came to the principal's office of the 'Beijing Academy of Science and Technology'.

"Hello, we are from the Jianghai City General Armament Department. My name is Zhao Zhongyao, and this is Director Liu Tianming Liu. Zhao Zhongyao looked at the tall and thin principal in front of him, and first introduced the identities of him and Liu Tianming to others.

This principal's name is Chen Yuanfeng, and as soon as he heard Zhao Zhongyao say this, he looked at him with some puzzlement and said, "My name is Chen Yuanfeng, I don't know, what are you looking for me." ”

"It's nothing, we came to you this time to find out if there are some top-notch talents in your school. Zhao Zhongyao said first.

"Our school is full of top-notch talent. Chen Yuanfeng listened to Zhao Zhongyao's words and said unceremoniously.

As soon as he heard Chen Yuanfeng say this, Zhao Zhongyao smiled and said: "I'm talking about very cutting-edge talents, that is, talents who have already made some achievements. ”

Chen Yuanfeng listened to Zhao Zhongyao's words, then he smiled again and said, "If you say so, then I can't judge it." We have a lot of cutting-edge talents in this school. But if you want to say that one student is the most cutting-edge talent, I really can't say. ”

After listening to Chen Yuanfeng's words, Zhao Zhongyao smiled again and said, "Then are the professors in your school very famous? I think your students may not have made any achievements." But your professor must have already made some achievements!"

"How can I say this? The professors in our school are all top-notch talents. In all aspects, it has its own achievements. But you don't know what you're looking for. Chen Yuanfeng looked at Zhao Zhongyao and Liu Tianming again and said.

Zhao Zhongyao listened to Chen Yuanfeng's words, smiled and said: "What we want to find is an expert in the study of engines, I don't know if you have anything here." ”

"Engine experts, do you want to develop military automobiles?" Chen Yuanfeng listened to Zhao Zhongyao's words, and felt that they wanted to study military automobiles. After all, Chen Yuanfeng also knew that Zhao Zhongyao and Liu Tianming were from the Jianghai General Armament Department, which showed that both of them were leaders in the military industry.

"It's not about military cars, it's about military fighters. Zhao Zhongyao looked at Chen Yuanfeng again and smiled.

As far as I know, our country has not yet independently developed a military fighter, so could it be that your Jianghai General Armament Department wants to develop a self-developed military fighter? ”

Although Chen Yuanfeng is not an expert in studying and researching military fighters, he is also a person who cares about the country's national defense construction, he is also a standard intellectual, and he is also very familiar with the current situation of the country's aviation industry.

In the case that many fields in China are dependent on imports, it is unthinkable to develop a new type of fighter independently developed.

"That's right, over the years, almost all the planes in our country have relied on imports! How can this work, our country is a big country in the East. If we had been relying on importing foreign aircraft, wouldn't it be very faceless! Therefore, we thought that we should develop an aircraft with its own brand, so that our country's aircraft could also be exported to other countries. Let our country's fighter jets also show their demeanor at the Bamboo Sea Air Show. ”

Zhao Zhongyao chatted with Chen Yuanfeng, what he saw and heard at the last Zhuhai Air Show, he mainly wanted Chen Yuanfeng to know that what they wanted to do was very important and meaningful.

"Well, Expert Zhao, your idea is good, but if you want to develop a new fighter of your own brand, it is very difficult. Some aviation departments in our country also tried to develop their own main brand of fighters, but they have not succeeded. You feel that this time, you will definitely be able to develop it. ”

As soon as Chen Yuanfeng heard Zhao Zhongyao say this, he felt that what Zhao Zhongyao said was a bit big. Their 'Beijing Institute of Science and Technology' is one of the most famous research universities in the country. Before, I also thought that I wanted to develop an advanced fighter to change the situation that the country has been lagging behind in this regard. But they studied it for a few years, but there was no progress. Because, in the study of aero engines, they have encountered a big problem, and no matter how they can, they cannot solve the reason why aero engines will turn off by themselves when they encounter strong cold air at high altitudes.

"Expert Zhao, I advise you not to study any new type of fighters, this will not work at all, with our country's scientific and technological talents, I am afraid that it will not be possible to solve the problem of this aero engine at all, and it will be impossible to develop any more advanced military fighters. ”

Chen Yuanfeng looked at Zhao Zhongyao, he didn't believe it, what Zhao Zhongyao said, he felt that what Zhao Zhongyao wanted to do now was really a little beyond his strength.

"President Chen, if you do what you said, then our country's military fighter planes will always rely on imports. If this is the case, then our country's aviation industry, especially the military aviation industry, will always lag behind the developed countries of the West? ”

Zhao Zhongyao saw that Chen Yuanfeng did not support what they did, so he defended Chen Yuanfeng-for-tat.

Liu Tianming didn't speak for a long time, he listened to Chen Yuanfeng's words, and then looked at Chen Yuanfeng and said: "President Chen, our country has not been able to develop advanced fighters before, and that is because our country has never had a genius in military industry before. And now, with such a military genius, we will, of course, be able to develop advanced fighters of our own brand. ”

As soon as he heard Liu Tianming say this, Chen Yuanfeng looked at Liu Tianming with some puzzlement and said, "Director Liu, what do you mean by this, what great military geniuses are there in our country, why haven't I heard of it!"

Although Zhao Zhongyao is somewhat famous, he is only somewhat famous in the military industry, and he is not very famous in the scientific and technological circles. After all, the research work that Zhao Zhongyao has done over the years has been in the field of military industry, and has not yet involved civilian aspects.

More importantly, Zhao Zhongyao has always worked in the Jianghai General Armament Department, and the capital is a relatively unfamiliar place for him. Although, Zhao Zhongyao can be regarded as an out-and-out top talent in Huaguo. But his fame is not known to many people in this capital area.

Liu Tianming listened to Chen Yuanfeng's words, then smiled and said: "The military genius I want to say, he is far away in front of him, I don't know, you don't understand what I mean." ”

As soon as he heard Liu Tianming say this, Chen Yuanfeng looked at Zhao Zhongyao in surprise and said, "In this way, this young expert Zhao is a great military expert. Of course, Chen Yuanfeng heard what Liu Tianming meant, and he immediately looked at Zhao Zhongyao and said the above words.

Zhao Zhongyao listened to Chen Yuanfeng's words, he was a little embarrassed, just looked at Chen Yuanfeng with a smile, and didn't say anything.

At this time, Liu Tianming looked at Chen Yuanfeng unceremoniously and said: "Of course, Zhao Zhongyao is the most famous military expert in our country, and he has replaced the gap in China's military industry in many research projects. The reason why our country's military industrial strength has grown so fast in recent years is the result of the efforts of Expert Zhao. ”
