There are many stories about the research process of our Air China's development, and Ye Chen also knows a lot. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 At that time, when he heard the story, he was very moved and emotional, but he was far from being able to tell Mo Lao, a person who witnessed it.

Listening to Mo Lao's narration, Ye Chen only felt heavy, his heart was panicked, and tears flowed out involuntarily.

The two hugged each other and cried, and after a while, their mood gradually calmed down.

"Mo Lao, it's not easy for you! It's not easy! Ye Chen looked at Mo Lao with admiration, and said with great sincerity: "It's really hard to imagine how you persevered. I've heard a lot of stories about this, but I'm still excited to hear you tell them. ”

"Xiao Ye, our generation has come out of a special era, and we have firm beliefs, as long as we still have a breath, we will continue to do it." Mo Lao's tone was very flat, as if he was talking about other people's business, but there was a sense of firmness.

"The happy life we have now is what you old-timers have spelled out. Mo Lao, don't worry, as long as I can contribute, I will do my best. "Ye Chen only feels that it is an incomparable honor to be able to contribute to the national defense of our country.

"Thank you, Xiaoye." Mo Lao nodded and said, "Our country's aviation industry has gone through disasters, and it can be said that it is congenitally insufficient. At the beginning of the founding of the People's Republic of China, our country was poor and white, we wanted money but no money, we wanted equipment but no equipment, and we wanted talented people, so it was very difficult to do both aviation and aerospace, so we had to choose one to do it. Our aviation did not give up, but received much less resources. ”

This matter, when Ye Chen was going to the Imperial City Root, he listened to Zhuang Lao on the plane. Although the decision at that time was in line with the actual situation of our country, it gave too few resources to aviation, making it difficult for the aviation industry.

"As the country's strength grows and the economic situation is getting better and better, the country is increasing its investment in aviation, which is paying off debts. Through our efforts, good achievements have been made. We've finally made it happen. Mo Lao was both embarrassed and proud.

"The state has set up a large aircraft company and an aero engine company to specialize in the aviation industry, and the situation is gratifying." Ye Chen also knows that the country has increased investment in aviation in recent years, and there have been many big moves. One of the biggest moves is the formation of COMAC and Aero Engine Group.

"There are many problems in our country in terms of aero engines, and the low investment of resources is a very important problem. Too scattered and resources are not integrated, which is also an important reason. Mo Lao said very pertinently: "There are several large aircraft factories in our country, and almost every one of them has an aero engine research and development institution. However, the scale of these institutions is not very large, and the strength is not strong enough. Moreover, our aviation is subject to aircraft, while foreign aircraft are due to engines. This time, the state set up a special aviation development company, which is to integrate resources. ”

There are really a lot of problems in our country's aviation industry, and the most important ones are three: one problem is that the resources invested in the past are small, which makes our country's aviation industry congenitally deficient and owes too many debts. Second, R&D institutions are scattered and their strength is not strong. The third is that aviation development is subject to aircraft, and what our country has always implemented is to develop what kind of aircraft to develop, and develop this type of engine. If the plane is dismounted, the aviation engine will also be dismounted.

In foreign countries, on the contrary, the aircraft has to be decided by the aviation development. Even if the aircraft stops researching, the technology of the aviation engine can continue to be used, and the aviation engine can continue to be studied.

Hangfa is known as the jewel in the crown of industry, and the general R&D cycle takes more than ten or twenty years, or even longer. This requires long-term investment and long-term technical accumulation. Hangfa is subject to the type of aircraft, if the plane is dismounted, Hangfa will also be dismounted. The disadvantages of this are too great, because Hangfa has just made a name for itself, and it has to stop and die in the bud.

"Even so, our aviation is no worse than abroad." Mo Lao was very proud.

"Really?" Ye Chen's eyes widened suddenly, this was great news, Ye Chen's breathing suddenly became short.

"Of course." Mo Lao was very sure and said: "When we set up the project, it was very clear that if we want to catch up with foreign advanced technology, it is impossible to follow behind others, that is to follow others and eat farts, which stinks." We have to find a specific path that is unique to us. So, all these years, we must be going our own way. When our aviation is made, the gap between us and foreign countries will not be too big. ”

"A very wise decision." Ye Chen praised it.

As you know, the Wright brothers invented the airplane in 1903. Then it was used on the battlefield during World War I, although the planes at that time were very poor. However, by the time of World War II, large-scale air battles appeared, and the Germans used aircraft in perfect harmony as part of the "blitzkrieg".

Most shockingly, Germany successfully developed a jet aircraft during World War II, which was the most advanced aircraft in the world at that time. After Germany surrendered, the United States captured the scientists. With the help of these scientists, the United States built a jet plane as quickly as possible, leading the trend of world aviation.

By the time our country established the project, we were decades behind the United States. If you don't follow your own specific path, but follow after others, how long will it take?

Therefore, for the wise decision of our country's aviation development R & D personnel, no matter how much praise.

"When our country's aviation development was made, there were indeed many problems, whether it was thrust or service life, there were many problems in all aspects. Western countries have even hyped up and belittled us to the point of being useless. However, over time, our aviation engines are getting better and better, already equipping the troops. "Mo Lao is extremely proud.

Although there has been news reporting on this for a long time, but after receiving confirmation from the mouth of Mo Lao, a participant, Ye Chen was still very excited, and said, "Mo Lao, you have worked hard. With every new technology, there are always problems. Those Western countries that belittle us have bad intentions, they always think that we have no reason to do what the Western world can't do, and they are really arrogant and arrogant. ”

With every new technology, there are always problems. Not to mention such a difficult system engineering as Hangfa, if there is no problem, it will be abnormal.

Facts have also proved that with the passage of time, our aviation engine is getting better and better, and we have already installed troops.

What kind of fighter was installed, Ye Chen knew, he was more interested in something else, and asked anxiously: "Mo Lao, how is the engine of our stealth fighter?" ”

"It's under development. It won't take much time to be ready for installation. "Mo Lao is full of confidence.

Ye Chen was greatly infected, and said, "That's good!" That's great! What about performance? ”

"You should know the performance of the stealth machine, right?" Mo Lao asked.

"Of course. At the air show just held, although the stealth fighter was unveiled for only one minute, I was shocked by the excellent performance, those flight actions were so beautiful, and it was a beautiful enjoyment to watch. Ye Chen didn't know how many times he had watched the video of the stealth plane's performance at the air show, he was very excited, and his voice was a little high.

"After our engine research is completed, the performance of the stealth fighter will be greatly improved." Mo Lao smiled and said, "The time is not far away." ”

"Mo Lao, you are the best!" Ye Chen was also very happy and encouraged.

"The engine performance of the stealth fighter is very good, not worse than foreign ones, and even more advanced in some aspects." Mo Lao changed his words and said, "However, we need your help. ”

"Mo Lao, you say. As long as I can do it, I will not say a word. Ye Chen patted his chest and reassured.

As a patriotic military fan, if he can contribute to Hangfa, Ye Chen will definitely be happy to do it.

"I'm here to help us with fadec." Mo Lao Dao.

FADEC is a full-authority digital electronic control system, which is the most advanced aircraft engine control technology available today. Conventional aeroblasting is controlled by a hydraulic machine, which requires a cam space surface to complete. However, the machining of the cam is too difficult, which leads to its accuracy is not high enough, so that there are many problems in obtaining the hydraulic control system.

In the seventies, the British put forward the theory of digital electronic control. Later, the United States and other countries entered this field one after another, and the United States came from behind and has always been in the leading position.

Our country only entered this field in the eighties of the last century, and now it has mastered a large number of key technologies. Moreover, it is already in use on our aircraft, which is a gratifying point.

The digital electronic control system is a spatial surface algorithm that replaces the cam with code, so that the accuracy is much higher.

The development of this technology has gone through multiple stages, first using this technology for a single component, and then developing into the use of this technology as a whole; First analog, then digital; First limited functionality, then full permission.

Using the full-authority digital electronic control system, the life of the aviation engine is longer, the weight is lighter, the energy consumption is lower, the efficiency is higher, and the maintenance time is extended and more accurate......

Through the full authority of digital electronic control, the aviation is very excellent and widely used. Whether it is military or civilian, whether it is a helicopter or an airplane, it can be used.

"Xiao Ye, I believe you have an understanding of the full-authority digital electronic control system, right?" Mo Lao looked at Ye Chen and said.

"Although I don't do this, I still know something, and I know the basics." The full-authority digital electronic control system control is one of the hottest technologies in the world, and Ye Chen will definitely understand some basic ones.

"That's good, it's a lot easier to say. At the heart of this technology is a microprocessor, which is now controlled electronically. However, the prospect of this technology should be that it can be controlled by photonic technology, and we want to upgrade to a full-authority digital photonic control system. And you've just mastered photonic chip technology, and we'd like to ask for your help. Mo Lao said hopefully: "If it succeeds, it will be great." ”

Ye Chen's eyes were shining, and he secretly thought to himself, I just made the third super light brain, which can be used to do this. When I exert my strength, I must be very handsome.
