Chapter 977: Beijing Science and Technology Institute

The first thousand and one chapter Beijing Institute of Science and Technology
After hearing what Liu Changyun said, Zhao Zhongyao smiled again and said, "Minister Liu, I'm sorry, the talents I need can't be picked out in our general equipment department."
When Zhao Zhongyao said this, Liu Changyun said in a puzzled manner: "Oh, the talents you need can't be found in our General Armament Department, so go there to pick them."
"You should go to the capital. Only when you go to the capital can you pick out some cutting-edge talents." Zhao Zhongyao knew that the capital was the political, economic and cultural center of the country. It is also the place with the highest concentration of talents in the country. Only in the capital can you find the talents you want.
After hearing what Zhao Zhongyao said, Liu Changyun thought for a while, and felt that what he said also made sense. Although there are some talents in their general equipment department, they are not the most sophisticated talents. Only by going to the capital can we find the most sophisticated talents.
"Well, Zhongyao, what you said makes sense. It seems that we are going to Beijing again." Liu Changyun knew that if he wanted to find some cutting-edge talents, he could only go to Beijing.
"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 should just let him and Zhao Zhongyao do it together. No need to trouble Liu Changyun anymore.
"Alright, let the two of you do this! 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 a lot of difficulties. Although he does not go to the capital, he can still help Zhao Zhongyao and Liu Tianming by telephone.
"Okay, that's it, we will set off tomorrow." Zhao Zhongyao knew that his time was tight, and to do this, he had to do it quickly.
"Well, you'll fly to the capital tomorrow! All the expenses on the road, I will reimburse you after returning." Liu Changyun looked at Zhao Zhongyao and Liu Tianming and said.
"Okay, let's go back first." Zhao Zhongyao said again.
In this way, on the next day, Zhao Zhongyao and Liu Tianming took another flight to the capital.
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 train top talents across the country. The researchers here are the best college students carefully selected from the top universities in the country. They all have the most cutting-edge expertise 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 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 use turbofan engines, and many small private jets, trainers or agricultural aircraft 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 and exhaustion 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 cars, and the more advanced ones have a V-shaped W-shaped arrangement.
However, due to the huge number of cars, countries all have stricter emission requirements and market competition is also huge. Therefore, major automakers are constantly using new technologies to improve product competitiveness. What in-cylinder direct injection, dual injection, stratified combustion, the introduction of Atkinson thermal cycle, variable valve timing, variable valve lift, harmonic interference intake, adjustment of valve overlap angle, high-speed combustion, etc. . In contrast to airplanes, the restrictions imposed by various civil aviation agencies on piston engines are not as strict as cars, and market competition is not as fierce as cars. Personally, I feel that the application of new technologies in 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 automobile engines and aero engines is 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 fuel. The mission of a heat engine is to use it. In the long history, the use of these energies by mankind only stayed at "heat generation", such as burning coal to cook food, making stoves in winter, and generating heat by friction. But by the time of the Industrial Revolution, Britain's forest resources are becoming increasingly scarce, and the demand for coal has increased, and mines have become more and more deep. It is becoming more and more tricky to drain water from mines, and it is becoming increasingly uneconomical to extract water by hand. This urgent need forces people to develop a pumping power machine. Put a small amount of water at the bottom of the cylinder to heat the cylinder, vaporize and expand internally, drive the piston to move upward, and then remove the heating source. The steam in the cylinder is condensed to form a vacuum. The piston falls under atmospheric pressure and the falling process provides power for pumping water. 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 where talents gather.
Zhao Zhongyao and Liu Tianming came to the most famous university of science and technology in Beijing. The two are here to select some outstanding talents. Naturally, we have to find the principal of this school first.
Under the leadership of a student, Zhao Zhongyao and Liu Tianming came to the principal's office of the Beijing Institute of Science and Technology.
"Hello, we are from the General Armament Department of Jianghai City. My name is Zhao Zhongyao, and this is Director Liu Tianming." Zhao Zhongyao looked at the tall and thin principal in front of him, and first identified him and Liu Tianming. Let me introduce it to others.
The principal was called Chen Yuanfeng. When he heard Zhao Zhongyao say this, he looked at him in a puzzled manner 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 some top-notch talents in your school." Zhao Zhongyao said first.
"Our school is all top-notch talents." Chen Yuanfeng said bluntly after hearing what Zhao Zhongyao said.
When Chen Yuanfeng said this, Zhao Zhongyao smiled and said: "I'm talking about very sophisticated talents, that is to say, talents who have made some achievements."
After listening to Zhao Zhongyao’s words, Chen Yuanfeng smiled again and said,
If you say that, then I’m not going to make a rash judgment. Our school has many cutting-edge talents. But you have to say, that student He is the most cutting-edge talent, I really can't tell."
After listening to Chen Yuanfeng’s words, Zhao Zhongyao smiled again and said,
Then, are your professors very famous? I think your students may not have made any achievements. But your professors should have been What achievements have you made!"
"How do you say this! The professors in our school are also regarded as cutting-edge talents. In all aspects, they have their own achievements. But I don't know what experts and professors 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."
"Engine experts, do you want to develop military cars!" Chen Yuanfeng heard what Zhao Zhongyao said, and felt that they wanted to study military cars. After all, Chen Yuanfeng also knew that Zhao Zhongyao and Liu Tianming were members of the Jianghai General Armament Department. This shows that they are both leaders in the military industry.
"It's not to study military cars, we both want to study military fighters." Zhao Zhongyao looked at Chen Yuanfeng again with a smile.
"What, it is not easy to study military fighters! As far as I know, our country has not independently developed a military fighter. Could it be that your Jianghai General Armament Department must develop an independent research and development. Of military fighters."
Although Chen Yuanfeng is not an expert in studying and studying military fighters, he is also a person who cares about national defense construction. He is also a standard intellectual, and he also knows the current state of the country's aviation industry.
With many fields in China relying on imports, it is unthinkable to research a new type of fighter aircraft independently developed.
"Yes, in recent years, almost all aircraft in our country have relied on imports! How can this be done? Our country is a major eastern country. If we always rely on imported aircraft, wouldn’t it be very shameless! , We thought, to develop an aircraft with its own brand, to allow our country’s aircraft to be exported to other countries. Let our country’s fighter jets also show off at the Bamboo Sea Air Show. "
Zhao Zhongyao and Chen Yuanfeng talked a bit. What he saw at the last Zhuhai Airshow, 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 aircraft of its own brand. Some aviation departments in our country also wanted to study their own The main brand fighter has never been successful. You feel that this time, you will be able to develop it successfully."
When 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 the most famous research university in the country. Before, I also thought about developing an advanced fighter jet, so as to change the country's lagging situation in this regard. But they have studied for several years, but there is no progress. Because they encountered a big problem in their research on aero engines. No matter how they did it, they could not solve the reason why aero engines would stall when they encountered strong cold air at high altitude.
"Expert Zhao, I advise you not to study any new type of fighter aircraft. This is simply not feasible. With our country’s scientific and technological talents, I am afraid that this aero-engine problem cannot be solved at all, and it is impossible to study anything more advanced. Military fighter."
Chen Yuanfeng looked at Zhao Zhongyao, he didn't believe it, what Zhao Zhongyao said, felt that what Zhao Zhongyao wanted to do now was really overwhelming.
"President Chen, if this is what you said, will our country's military fighter planes always rely on imports. If this is the case, then will our country's aviation industry, especially the military aviation industry, always lag behind the West? Developed countries."
When Zhao Zhongyao saw that Chen Yuanfeng didn't support what they were doing, he defended Chen Yuanfeng for tat.
Liu Tianming didn't speak for a long time. He listened to Chen Yuanfeng's words and looked at Chen Yuanfeng and said: "President Chen, our country has not been able to develop advanced fighter aircraft before. That is because our country has never had a military genius before. Now that we have such a military genius, we can of course develop advanced fighters of our own brand."
Upon hearing Liu Tianming's words, Chen Yuanfeng looked at Liu Tianming in confusion and said, "Director Liu, what do you mean by this? Why haven't I heard of any great military genius in our country!"
Although Zhao Zhongyao is somewhat famous, he is only somewhat famous in the military industry. In the scientific and technological circles, he is not very famous. After all, the research work that Zhao Zhongyao has done over the years has been in the military industry, and has not yet involved civilian aspects.
More importantly, Zhao Zhongyao has always worked in the Jianghai General Armament Department. For him, Beijing is also a relatively unfamiliar place. Although, Zhao Zhongyao can be regarded as an out-and-out top talent in China. But his fame is not known to many people in this capital area.
After hearing what Chen Yuanfeng said, Liu Tianming smiled and said: "The military genius I want to talk about, he is far away in the sky and is right in front of you. I don't know. Do you understand what I mean."
When Liu Tianming said this, Chen Yuanfeng looked at Zhao Zhongyao in amazement and said: "So, this young expert Zhao is a great military industry expert." Of course, Chen Yuanfeng heard what Liu Tianming meant. , He immediately watched Zhao Zhongyao say the above.
Zhao Zhongyao heard what Chen Yuanfeng said, he was a little embarrassed, but he looked at Chen Yuanfeng with a smile, and said nothing.
At this time, Liu Tianming looked at Chen Yuanfeng unceremoniously and said:
Of course, Zhao Zhongyao is the most famous military industry expert in our country. He has done many research projects to replace the gaps in my country’s military industry. The reason why the military strength of the past few years has grown so fast is the result of the efforts of experts Zhao."
