Super Scientist

There are many stories about the difficult research process of Air China, and Ye Chen also knows a lot. At that time, he was very moved when he heard the story, but it was far from being powerful enough to tell the story to Mo Lao, who had witnessed it.

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

The two hugged each other and wept. After a while, the 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 sincerely: "It's really hard to imagine how you persisted. Although I have heard a lot of this story, but it’s still exciting to hear from you.”

"Xiaoye, people of our generation have all come out of a special age, and have firm beliefs. As long as there is still breath left, we will continue to work." Mo Lao's tone was very flat, as if he was talking about other people's affairs, but, through With a firmness.

"Our current happy life is made by you old seniors. Don't worry, Mr. Mo, as long as I can contribute, I will do my best." Ye Chen only feels that it is an incomparable honor to contribute to our country's national defense.

"Thank you Xiaoye." Mo Lao nodded and said: "Our country's aviation industry has experienced catastrophe, and it can be said that it is congenitally deficient. At the beginning of the founding of the country, our country was poor and empty. We needed money but no money, needed equipment but no equipment, and needed talents but no talents. It is difficult to do both aviation and aerospace, and we have to choose one to do. After careful consideration, our country has decided to give priority to the development of aerospace. Our aviation has not given up, but we have received much less resources.”

When Ye Chen was going to Huangchenggen, he heard Mr. Zhuang talk about it 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, which made the aviation industry difficult.

"As the strength of the country increases and the economic situation gets better and better, the country increases its investment in the aviation industry, which is repaying debts. After our efforts, we have achieved good results. We finally made the aviation development It's gone." Mo Lao was both sad and proud.

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

"Our country has a lot of problems in aero engines, and the lack of resource investment is a very important problem. It is too scattered and the resources are not integrated, which is also an important reason." Mo Lao said very pertinently: "Our country has There are several large aircraft manufacturers, and almost every family has an aero-engine research and development institution. However, these institutions are not large in scale and not strong enough. Moreover, our aviation development is controlled by the aircraft, while foreign countries rely on the development of aircraft engines. This time, the country established a special aviation development company to integrate resources.”

There are quite a few problems in our country's aviation industry, the most important of which are three: one problem is that the lack of resources invested in the past made our country's aviation industry inherently deficient and indebted too much. Second, R\u0026D institutions are scattered and not strong. The third is that aviation development is subject to aircraft. What our country has always practiced is to develop the engine of this type of aircraft. If the plane dismounts, Hangfa will follow suit.

In foreign countries, it is just the opposite, and the aircraft has to be decided by the aviation industry. Even if the research on the aircraft is stopped, the technology of Hangfa can still be used, and the research of Hangfa can continue.

Hangfa is known as the jewel in the crown of the industry, and the general research and development cycle takes ten to twenty years, or even longer. This requires long-term investment and long-term technology accumulation. Aviation Development is subject to the model of the aircraft. If the aircraft is dismounted, Aviation Development will also be dismounted. The disadvantages of doing so are too great, because Hangfa has just made a name for itself, and has to stop, dying in its infancy.

"Even so, our aviation development is no worse than that of foreign countries.

"Mr. Mo is very proud.

"Really?" Ye Chen's eyes widened sharply. This was great news, and Ye Chen's breathing became short of breath.

"Of course." Mo Lao was very sure, and said: "When we established the project, we knew very well that if we want to catch up with foreign advanced technology, we can't follow others. It should not be heard. We have to walk out a specific path that belongs to us. Therefore, we must be walking our own path in these years. When our aviation development is completed, the gap between us and foreign countries will not be too big.”

"Very wise decision." Ye Chen greatly appreciated it.

As you all know, the Wright Brothers invented the airplane in 1903. Then it was used on the battlefield during World War I, although the aircraft at that time were very poor. However, by the time of World War II, large-scale air battles appeared, and the Germans were proficient in the use of aircraft, which was an integral part of the "Blitzkrieg".

The most shocking thing is that Germany successfully developed 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 these scientists. With the help of these scientists, the United States built jet aircraft at the fastest speed, leading the trend of world aviation.

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

Therefore, no matter how much we praise the wise decision of our country's aviation development personnel, we can't praise it too much.

"When our country's aviation development was first produced, there were indeed many problems, whether it was thrust or service life, there were many problems in all aspects. Western countries even made a lot of hype and demoted us to nothing. However, with the passage of time As time goes on, our aviation engine is getting better and better, and we have equipped our troops." Mo Lao was extremely proud.

Although there have been news reports on this matter for a long time, Ye Chen was still very excited after getting confirmation from Mo Lao, a participant, and said: "Mo Lao, you have worked hard. When every new technology appears, always There will be problems. Those Western countries who belittle us have bad intentions. They always think that we have no reason to do what the Western world can’t do. It’s really arrogant and arrogant.”

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

Facts have also proved that as time goes by, our aviation equipment is getting better and better, and it has already been installed in the army.

Ye Chen knew what kind of fighter jets were being deployed, and he was more interested in other things, so he hurriedly asked, "Old Mo, what happened to the engines of our stealth fighter jets?"

"It's under development. It won't take long before it can be installed." Mo Lao is full of confidence.

Ye Chen was greatly affected, and said: "That's good! Great! What about the 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 its excellent performance. Those flying movements are so beautiful, it is a kind of beautiful enjoyment to watch." Ye Chen had watched the performance video at the exhibition many times, and he was very excited, with a high-pitched voice.

"After our engine research is completed, the performance of the stealth fighter will be greatly improved." Mo Lao said with a smile: "The time is not far away."

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

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

"Mr. Mo, tell me. As long as I can do it, I will never say anything else." Ye Chen patted his chest and promised.

As a patriotic military fan, Ye Chen would definitely be willing to do so if he could make a contribution to Hangfa.

"I'm here this time because I want you to help us at FADEC." Mo Lao said.

FADEC is the full authority digital electronic control system, which is the most advanced aircraft engine control technology. Traditional aviation is controlled by hydraulic machinery, which requires a cam space surface to complete. However, the machining of the cam is too difficult, resulting in insufficient precision, causing many problems in the hydraulic control system.

The United Kingdom put forward the theory of digital electronic control in the 1970s. 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 lead.

Our country only entered this field in the 1980s, and has mastered a large number of key technologies until now. Moreover, it is already being used in our aircraft, which is a gratifying point.

The digital electronic control system uses the code to replace the space surface algorithm of the cam, so the precision is much higher.

The development of this technology has gone through multiple stages. First, a single component uses this technology, and later it develops to use this technology as a whole; first it is analog, then it is digital; first it is limited function, and then it is full authority control.

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

The aviation engine controlled by full-authority digital electronics is excellent and has a wide range of applications. Whether it is military or civilian, whether it is a helicopter or an aircraft, it can be used.

"Xiaoye, 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 work in this area, I still have some understanding, and I know the basics." Full-authority digital electronic control system control is one of the most popular technologies in the world, and Ye Chen will definitely understand some basics.

"That's good, it's much simpler to say. The core of this technology is a microprocessor, which is now controlled by electronic technology. However, the prospect of this technology should be that it can be controlled by photonic technology. Authority digital photon control system. And you happen to have conquered photon chip technology, we want to ask you for help." Mo Lao said hopefully: "If it succeeds, it must be great."

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