Take Off My Aviation Era

Professor Sun’s voice unfolded slowly at the scene in the form of voice-overs. This is not because the professor Sun deliberately took it up, but that the professor Sun Yisun had polio when he was young and caused him to walk. It’s very difficult. It’s very hard to walk around the test site every day, so Zhuang Jianye deliberately installed a set of video surveillance and real-time voice systems so that Professor Sun can monitor all areas of the test site while walking as little as possible. Case.

Of course, if you change to someone else, let alone walking hard, your legs are broken. When you see so many high-level leaders coming, you will have to climb to the scene and make a good impression in front of all the leaders.

But Professor Sun was not such a person. If it weren't for that, he would be upset with the factory led by the head of the aerospace manufacturing plant at the Beijing University of Aeronautics and Astronautics.

If Sun Yi didn't do scientific research, academic work, or experimentation, it was a whole-hearted rush.

However, at certain levels and positions, you can not only do these academic things, you can eat the so-called results, but also engage in some interpersonal relationships, strengthen leadership, fight for subordinates’ welfare, review and review seniority, and in short, scientific research External affairs accounted for 90%, and most of the remaining 10% were in intrigue.

Due to his physical disability and the temperament of studying hard, Sun Yi was very bad at being a man, but he couldn't stand Sun Yi's natural hegemonic physique, so he ruled the roost every exam, so he started from middle school. After opening up all the way, he eventually became the first batch of publicly funded international students after the reform and opening up, and brought his miracle of dominating the examination room to the United States on the other side of the ocean, thus becoming the legend of the MIT Applied Materials Department.

Such people will naturally be reused when they return to their country. In fact, Sun Yi did get a lot higher than his peers in terms of grade treatment, and even a height that many people can't reach in a lifetime.

But in terms of the environment, Sun Yi is really uncomfortable. He wants a quiet research environment. Unfortunately, he feels that he has reached his position. It is ridiculous to talk about scientific research. If you want to talk, you should talk about politics and principles. !

But in Sun Yi's case, the so-called politics and principles are actually very simple, that is, do your own thing well and show your strengths.

However, the general environment made Sun Yi’s simple ideal lack the so-called sense of mission, so Sun Yi, who didn’t understand these things, became more and more uncomfortable. At the same time, including the person in charge of the aviation manufacturing plant, many people expressed their opinions on Sun Yi. Yi's evaluation is that the books for so many years have been read for nothing. What use is there even if the interpersonal relationship is not good?

Under such circumstances, Sun Yi, exhausted physically and mentally, finally offered to resign and was ready to go to the United States. Even if the United States was in trouble, at least he would be able to give him a quiet place to conduct research.

As soon as Sun Yi left, his leading research on ceramic heat-resistant coating materials came to a halt. There is no way. Now the gap between domestic ceramic materials research and the international mainstream is quite large, so he specializes in applied materials at MIT Sun Yi of ceramic materials became an authority in this field as soon as he returned to China.

Otherwise, the person in charge of the aviation development factory would not be able to come to the door and engage in any kind of cooperation with birds. The result was that the good cooperation was caused by them to be nonsense, and finally Sun Yi was angry and left.

However, the person in charge of the aviation manufacturing plant and others did not care too much. After all, Sun Yi left and left a lot of things. Even if it stops completely, he can extract one or two application technologies from the existing results. , Becoming the person in charge of the aviation manufacturing plant will not have much political achievements and qualifications.

But Sun Yi, who was supposed to go to the United States, actually appeared at Ascendas Group’s Aviation Development Test and Research Center, which surprised the person in charge of the Aviation Development Manufacturing Plant, but he hadn’t waited for the responsibility of the Aviation Development Manufacturing Plant. People digested this information, and Sun Yi's next paragraph almost failed to smash the fragile heart of the head of the aviation manufacturing plant like a heavy hammer.

"Now the No. 1 and No. 4 engines of the TNB-19 aviation test machine have been disassembled. This WD-66 large bypass ratio turbofan, the core machine is the same as the WD-62MVP, and it is our group's 2.5-generation core machine. , This core engine has a characteristic, that is, it adopts the integrated design of the combustion chamber and the high-pressure turbine guide. The advantage of this is that the high-temperature jet from the combustion chamber can make frantic when passing through the high-pressure turbine guide. The heat flow is completely straightened out, so that it is more efficient when driving the high-pressure turbine to rotate, and at the same time, it will increase the service life of the turbine, thereby greatly extending the interval between aircraft engine overhauls.

However, to do so, it is necessary to ensure that the guide blades on the high-pressure turbine guide can withstand the impact and burning of the high-temperature heat flow up to 1300 degrees Celsius, so extremely high requirements are placed on the blades.

To this end, I proposed two technical routes. One is actually the original nickel-based metal alloy guide vane sprayed with a ceramic heat-resistant layer, just like the high-pressure turbine guide of the No. 4 engine; the other is reinforced with a ceramic base. Type composite material is used as the guide vane, and the first machine uses this record route.

Facts have proved that my second set of solutions is obviously more effective than the first set. You can take a closer look at the two engines. Their flight time is about 120 hours. However, the fourth aircraft with ceramic heat-resistant coating The guide blades on the high-temperature turbine guide have visible defects, so the state of the fourth unit is not stable; on the other hand, the first unit, using the brand-new ZBF-600 ceramic-based material, is still intact, and the thrust of the engine is always In good flight condition. "

Hearing what Professor Sun said, the heads of the aviation manufacturing plant, including the deputy director, hurriedly went back and forth between Unit 1 and Unit 4 and watched it over and over dozens of times. It was confirmed that what Professor Sun said was correct. There were indeed several defects on the blades of the high-pressure turbine guide on the fourth plane. Although it was not obvious, it was indeed a great defect in precision products such as aero engines.

In contrast to the No. 4 machine, the No. 1 machine ~www.readwn.com~ not only can't see the defect with the naked eye, even if it is measured with a flaw detection instrument, it can't find any faults.

Which one is better or worse, let alone a group of senior people present, even a sensible child can tell the difference without hesitation.

At this time, the people in charge of the aviation manufacturing factory who thought they had gained the first hand fell into collective silence again, and then, including the deputy director, all looked directly at the aviation manufacturing factory that was rigid with Zhuang Jianye. principal.

"Everyone, our factory's ceramic coating spraying technology is absolutely guaranteed. We must know that all our spraying equipment is imported from Japan. The meticulous craftsmanship is definitely not comparable to domestic products..."

"Okay, my leader, you can imagine that Japanese equipment is used in aviation development. Even they dare not use it. Congratulations. The Japanese will definitely appreciate you. In that case, please help. Busy..." The person in charge of the Hangfa Manufacturing Factory wanted to forcefully explain, but before he could finish his words, he was interrupted by Zhuang Jianye with a smile, and immediately squeezed a guide vane that he didn't know where it came from into the hand Here, he patted the opponent's thick hand: "Take this guide vane to the Japanese and see if they can use the Japanese craftsman spirit of hanging hair to make it intact for Lao Tzu!"
