Chapter One Thousand and One

After hearing Liu Changyun's words, Zhao Zhongyao smiled again and said, "Minister Liu, I'm sorry, the talents I need may not be available in our General Armament Department."

Hearing what Zhao Zhongyao said, Liu Changyun said a little puzzled: "Oh, the talents you need cannot be selected in our General Armament Department, so we have to go there to find them."

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

After listening to Zhao Zhongyao's words, Liu Changyun thought for a while, and felt that what he said 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 go with you! Minister Liu is busy with work, so he doesn't need to run errands anymore." Liu Tianming felt that he and Zhao Zhongyao should do this together. Don't bother Liu Changyun anymore.

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

Liu Changyun also knows that it is not easy to find some cutting-edge talents. In the process of searching, you will definitely encounter many difficulties. Although he doesn't go to the capital, he can also help Zhao Zhongyao and Liu Tianming by phone.

"Okay, that's it. We will set off tomorrow." Zhao Zhongyao knew that his time was tight, and he had to do it quickly if he wanted to do this.

"Well, you can take a plane to the capital tomorrow! I will reimburse you for all the expenses on the way 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, on the next day, Zhao Zhongyao and Liu Tianming flew to the capital again.

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

This 'Beijing Institute of Science and Technology' is a place to cultivate top talents in the country. The scientific researchers here are all the best college students carefully selected from the top universities in the country. They all master the most cutting-edge professional technologies in various industries.

Zhao Zhongyao knew that 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 component with the highest technological content.

Aircraft engines are different from ordinary engines.

Most family cars on the market use piston engines.

Airplanes are different. There are piston engines and gas turbines. Modern mainstream commercial airliners all use turbofan engines, and many small private jets, trainers or agricultural machines use piston engines.

If it is a piston engine, the basic principle is not much different. Simply put, it is the four strokes of intake, compression, work and 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. Most airplanes are arranged in a star shape or horizontally opposed. There are more in-line cars on the car, and the more advanced ones are arranged in a V-shape and a W-shape.

However, due to the large number of cars, countries have relatively stringent emission requirements, and the market competition is also huge. Therefore, major car manufacturers are constantly using new technologies to improve product competitiveness. In-cylinder direct injection, dual injection, stratified combustion, introduction of Atkinson thermodynamic cycle, variable valve timing, variable valve lift, harmonic interference intake, adjustment of valve overlap angle, high-speed combustion, etc. . In contrast to airplanes, civil aviation agencies have not imposed stricter restrictions on piston engines than automobiles, and the market competition has not been as fierce as automobiles. Personally, I feel that the application of new technologies on car engines is far more fun than piston engines on airplanes.

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

The so-called heat engine is to convert the thermodynamic energy of matter 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. To understand the essential difference between the two, we must first understand the fundamental principle of heat engine energy conversion.

The most fundamental energy source of a heat engine is the energy of fuel. The mission of a heat engine is to utilize it. In the long history, the use of these energies by human beings has only been limited to "heat production", such as burning coal to cook food, lighting stoves in winter, friction to generate heat, and so on. But by the time of the Industrial Revolution, Britain's forest resources became increasingly scarce, the demand for coal increased, and the number of mines also increased and deepened. Pumping water out of mines is getting trickier, and traditional manual lifting is becoming less economical. This urgent need forces people to develop a kind of pumping power machinery. Put a small amount of water at the bottom of the cylinder, heat the cylinder, vaporize, and expand inside, driving the piston to move upwards, then remove the heat source, the steam in the cylinder condenses to form a vacuum, the piston falls under atmospheric pressure, and the falling process provides power for pumping. This is the earliest forming heat engine.

Although Huaguo's professional scientific and technological talents are not very good, there are still some such high-level talents in the capital, a place where talents gather.

Zhao Zhongyao and Liu Tianming came to the most famous university of science and technology in the capital together. The two are here to pick some great talent. Naturally, we must first find the principal of this school.

exist

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

"Hello, we are from the General Armament Department of Jianghai City. 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, first he and Liu Tianming's identities, I introduced it to others.

The principal's name is Chen Yuanfeng. When he heard what Zhao Zhongyao said, he looked at him puzzled and said, "My name is Chen Yuanfeng. I don't know. What can you do with me?"

"It's nothing. We came to you this time to find out if there are any outstanding talents in your school." Zhao Zhongyao said first.

"Our school is full of top talents." Chen Yuanfeng said bluntly after hearing Zhao Zhongyao's words.

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

After hearing Zhao Zhongyao's words, Chen Yuanfeng smiled again and said, "If you say that, then I won't be able to judge rashly. Our school has many cutting-edge talents. But if you want to say, that student It is the most cutting-edge talent, I really can't tell."

After hearing what Chen Yuanfeng said, 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 yet. But your professors should have already What have you accomplished!"

"How should I say this! The professors in our school are all cutting-edge talents. They have made their own achievements in various aspects. But I don't know what kind of expert professor you are looking for." Chen Yuanfeng looked at Zhao Zhong again Yao and Liu Tianming said.

After hearing what Chen Yuanfeng said, Zhao Zhongyao smiled and said, "We are looking for experts in engine research. I wonder if you have any here."

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

"It's not that we want to study military vehicles. The two of us want to study military fighter planes." Zhao Zhongyao looked at Chen Yuanfeng again and smiled.

"What, it's not easy to study military fighters! As far as I know, our country has not independently developed a military fighter yet. Could it be that your Jianghai General Armament Department is going to develop an independently developed one? military aircraft."

Although Chen Yuanfeng is not an expert in studying military fighter jets, he is also a person who cares about national defense construction. He is also a standard intellectual, and he also knows the current situation of the country's aviation industry very well.

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

"That's right, our country has relied on imports for almost all of its aircraft over the years! How can this work? Our country is a big country in the East. Wouldn't it be shameful to rely on importing foreign aircraft all the time! So , We just thought about developing an aircraft with our own brand, so that our country's aircraft can also be exported to other countries. Let our country's fighter jets also show their style at the Zhuhai Air Show. "

Zhao Zhongyao chatted with Chen Yuanfeng for a while. What he saw and heard at the last Bamboo Sea Air Show, he mainly wanted to let Chen Yuanfeng know that what they wanted to do was very important and meaningful.

"Well, expert Zhao, your idea is good, but it is difficult and difficult to develop a new type of fighter jet with its own brand. Some aviation departments in our country also wanted to develop their own The fighter plane of the main brand has never been successful. You feel that you will be able to develop it successfully this time."

When Chen Yuanfeng heard what Zhao Zhongyao said, he felt that what Zhao Zhongyao and the others said was a bit big. Their 'Beijing Institute of Science and Technology' is the most famous research university in the country. Before, I also thought about developing an advanced fighter so as to change the situation that the country has been lagging behind in this respect. But they have been studying for several years, but there is no progress. Because they encountered a big problem in the research of aero-engines. No matter what they did, they couldn't solve the reason why aero-engines would shut off by themselves when they encountered strong cold air at high altitude.

"Expert Zhao, I advise you not to study any new fighter jets. This is simply not feasible. With our country's scientific and technological talents, I am afraid that it is impossible to solve the problem of this aero engine, and it is impossible to develop any more advanced ones. military aircraft."

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

"Principal Chen, if what you said is like this, will our country's military fighter jets have to rely on imports? If so, will our country's aviation industry, especially the military aviation industry, always lag behind the West? developed countries."

Zhao Zhongyao saw that Chen Yuanfeng did not support what they were doing, so he argued with Chen Yuanfeng tit for tat.

Liu Tianming did not speak for a long time. After hearing what Chen Yuanfeng said, he looked at Chen Yuanfeng and said, "Principal Chen, our country has not been able to develop advanced fighter jets before, and that is because our country has never had a military genius before. Now that we have such a military genius, we can certainly develop advanced fighter jets of our own brand."

Upon hearing what Liu Tianming said, Chen Yuanfeng looked at Liu Tianming in a puzzled manner and said, "Director Liu, what are you talking about?

What do you mean, why haven't I heard of any great military geniuses in our country! "

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

More importantly, Zhao Zhongyao has always worked in the Jianghai General Armament Department, and the capital city 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, in this capital area, is not known to many people.

After hearing what Chen Yuanfeng said, Liu Tianming smiled and said, "The military genius I want to talk about is far away in the sky and right in front of me. I don't know, do you understand what I mean?"

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

After hearing what Chen Yuanfeng said, Zhao Zhongyao was a little embarrassed, but just looked at Chen Yuanfeng with a smile and didn't say anything.

At this time, Liu Tianming looked at Chen Yuanfeng bluntly and said: "Of course, Zhao Zhongyao is the most famous military industry expert in our country. He has filled in the gaps in our country's military industry in many research projects. The reason why the strength of the military industry has grown so fast over the past few years is the result of the hard work of Expert Zhao."
