There are many stories about the difficult research process of Air China. Ye Chen also knows a lot. At that time, when he heard the story, he was very moved and moved, but he was far from being able to talk to Mo Lao, a witness.
Listening to Mo Lao's remarks, Ye Chen only felt heavy, panicked in his heart, and tears shed involuntarily.
The two hugged and wept. 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 sincerely: "It's really hard to imagine how you persisted. Although I have heard a lot of this Aspect of the story, but when you hear it, you are still very excited. "
"Xiaoye, our generation has come out of a special era, and we have a firm conviction, as long as there is still a breath, we must continue." Mo Lao's tone was very flat, as if talking about other people's affairs, but, transparent With a firmness.
"The happy life we ​​have today is made up by your old predecessors. Mo Lao, rest assured, as long as I can contribute, I will do my best." Ye Chen only felt able to contribute to the national defense cause of our country, it is extremely glorious.
"Thank you, Xiaoye." Mo Lao nodded and said, "Our country's aviation industry has gone through tribulations, and it can be said to be inherently inadequate. At the beginning of the founding of our country, our country was poor and poor. We had no money, no equipment, no equipment. It is difficult to do both aviation and aerospace, and we have to choose one. After careful consideration, our country decided to give priority to the development of aerospace. We have not given up aviation, but we have a lot less resources. "
Ye Chen heard Zhuang Lao talking on the plane when he went to Huangchenggen. Although the decision at that time was in line with the actual situation of our country, this gave too few resources to aviation and made the aviation industry difficult.
"With the strengthening of the country, the economic situation is getting better and better, and the country is increasing its investment in the aviation industry, which is paying off debts. After our efforts, we have achieved good results. We finally made the aviation development "Mr. Mo is both sighing and proud.
"The state 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 state has increased its investment in aviation in recent years and has made a lot of moves. One of the biggest actions is to set up COMAC and Aero Engine Group.
"Our country has a lot of problems with aero engines, and it is a very important problem to invest less resources. It is too scattered and the resources are not integrated, which is also an important reason." Mo Lao is very permissive: "Our country has There are several large aircraft manufacturing plants, and almost every one has aero engine research and development institutions. However, these institutions are not large in scale and not strong enough. Moreover, our aviation development is subject to aircraft, and foreign countries Come. This time, the country set up a special aviation development company to integrate resources. "
There are really a lot of problems in the aviation industry in our country. The most important ones are three. One problem is that the resources invested in the past have made the aviation industry in our country inadequate and indebted. Second, R & D institutions are scattered and not strong. The third is that aviation development is subject to aircraft. What our country has always been doing is to develop engines for this type of aircraft. If the plane is dismounted, Hangfa will dismiss it.
The opposite is true in foreign countries, where the aircraft has to be determined by air departure. Even if the aircraft ceases to be researched, aviation technology can still be used, and aviation development can be further studied.
Hangfa claims to be the jewel in the industrial crown, and the general R & D cycle is more than ten or twenty years, or even longer. This requires long-term investment and long-term technical accumulation. Hangfa is subject to the model of the aircraft. If the plane is dismounted, Hangfa will also follow. The disadvantages of this approach are too great, because Hangfa has just made a name for itself and has to stop again, dying in its infancy.
"Even so, our aviation is not worse than abroad." Mo Lao is proud.
"Really?" Ye Chen's eyes widened sharply. This was great news, and Ye Chen's breathing suddenly increased.
"Of course." Mo Lao was very sure, said: "When we set up the project, it was very clear that if we want to catch up with advanced foreign technology, it is impossible to chase after others. Unheard. We have to go out of a specific path that belongs to our originality. So, these years, we must go our own way. When our aviation is done, the gap between us and foreign countries will not be too big. "
"Very wise decision." Ye Chen praised.
As we all know, the Wright brothers invented the aircraft in 1903. It was then 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, a large-scale air battle had emerged. The use of airplanes by the Germans was pure and green, and was part of the "blitz."
The most shocking thing is that Germany developed a jet aircraft during World War II, which was the most advanced aircraft in the world at that time. After the German surrender, the United States captured the scientists. With the help of these scientists, the United States has built jet planes as fast as possible, leading the trend of world aviation.
By the time our country sets up a project, we are decades behind the United States. If you do n’t follow your own path, but follow someone else, what time will it take?
Therefore, no matter how much we praise the wise decision of our national aviation development researchers.
"When our country's aviation was made, there were indeed a lot of problems, whether it was thrust or service life, there were many problems in all aspects. Western countries were even more hype and devalued us. But over time, Over time, our navigation is getting better and better, and we have been equipped with troops. "Mo Lao is extremely proud.
Although there have been news reports about this, but from the mouth of the participant Mo Lao, Ye Chen is still very excited, saying: "Mo Lao, you have worked hard. When every new technology appears, always There will be problems. Those Western countries that disparage us have no good intentions. They always think that we ca n’t make things that the Western world cannot do. They are really arrogant and arrogant. "
With every new technology, there are always problems. Not to mention the difficult system engineering of Hangfa, if there were no problems, it would be abnormal.
Facts have also proven that over time, our aviation has become better and better, and troops have been installed.
Ye Chen knew what kind of fighters were installed. He was more interested in something else, and hurriedly asked, "Mr. Old, what is the engine of our stealthy fighter?"
"It's under development. It won't take long for it to be installed." Mo Lao was confident.
Ye Chen was infected and said, "That's good! Great! What about performance?"
"You should know the performance of stealth machines, right?" Mo Lao asked.
"Of course. At the air show just held, although the stealth fighter appeared for only one minute, I was amazed by the excellent performance. Those flying actions are too beautiful, and watching is a beautiful treat." Ye Chen didn't know how many times he had watched the performance video at the exhibition. He was particularly excited and had a high pitch.
"After the completion of our engine research, the performance of stealth fighters will be greatly improved." Mo Lao smiled and said: "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 countries, and even more advanced in some aspects." Mo Laohua Feng turned around and said, "However, we need your help."
"Mo Lao, you say. As long as I can do it, I will say nothing." Ye Chen promised with a pat on the chest.
As a patriotic military fan, if he can contribute to aviation development, Ye Chen will certainly be willing to do it.
"I'm here this time, I just want you to help us at FADEC." Mo Lao said.
FADEC is a full authority digital electronic control system, which is the most advanced aircraft engine control technology now. Traditional avionics 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 accuracy, which makes many problems to the hydraulic control system.
In the 1970s in the United Kingdom, the theory of digital electronic control was proposed. Later, the United States and other countries have successively entered this field, and the United States has later taken the lead and has been in the lead.
Our country only entered this field in the 1980s, and now it has mastered a large number of key technologies. And, it's already being used in our aviation, which is a pleasing point.
The digital electronic control system is to replace the cam's space curved surface algorithm with code, so the accuracy is much higher.
The development of this technology has gone through multiple stages. First, it was used by a single component, and later it was developed to use this technology as a whole; first, analog, then digital; first, limited functions, and then full authority control.
Using the full-authority digital electronic control system, the aircraft has a longer life, lighter weight, lower energy consumption, higher efficiency, and more accurate maintenance time extension ...
The avionics controlled by full-authority digital electronic control is excellent and widely used. It can be used for military or civilian use, whether for helicopters or aircraft.
"Xiaoye, I believe you know the full power digital electronic control system, right?" Mo Lao looked at Ye Chendao.
"Although I didn't do this, I still know something. The basic things are known." Full power digital electronic control system control is one of the most popular technologies in the world. Ye Chen will definitely understand some basics.
"That's good, it is 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 photon technology, and we want to upgrade to full Digital photon control system with authority. And you just happened to overcome the photon chip technology, and we want to ask you for help. "Mo Lao said hopefully:" If it is successful, it must be great. "
Ye Chen's eyes were glittering, and I was secretly thinking. I just made the third super light brain, which can be used to do this. I must be handsome when I exert myself.
