Chapter 1208

Professor Sun's voice slowly unfolded on the scene in the form of voice over. It's not that Professor Sun deliberately raised it, but that Professor Sun Yisun suffered from poliomyelitis when he was young, which made it very difficult to walk. Every day he walked around the experimental site very painstakingly, so Zhuang Jianye specially installed a set of video monitoring and real-time voice system, so that Professor Sun could understand it Enough to be able to monitor the situation of each area of the test site with as little walking as possible.

Of course, if you change to other people, not to mention walking hard, your legs are broken. When you see so many high-level leaders coming, you have to climb to the scene to make a good impression in front of all the leaders.

But Professor Sun is not such a person. If not, when he was in Beijing University of Aeronautics and Astronautics, he was not happy with the factory led by the person in charge of the aviation development factory, who was just Zhuang Jianye.

To engage in scientific research, academic research and experiment, Sun Yi said that he was wholeheartedly striving for success.

However, at some levels and positions, we can not only do these academic things, but also engage in some interpersonal relationships, curry favor with powerful leaders, strive for the welfare of subordinates, judge and rank seniority. In a word, 90% of the things other than scientific research account for, and most of the remaining 10% are in collusion.

Due to his physical disability and his long-term study habit, Sun Yi is not good at dealing with people. However, he can't stand the fact that Sun Yi was born to be a student bully and won the championship in exams. From middle school on, Sun Yi became the first batch of public funded international students after the reform and opening up, and brought his miracle of dominating exam rooms to the United States, It became the legend of MIT applied materials department.

In fact, from the level of treatment, Sun Yi really got much higher things than his peers, even a height that many people can't reach in their lifetime.

But in terms of environment, Sun Yi is really not suitable. He wants a quiet environment for scientific research. Unfortunately, when he is in his position, it's ridiculous to talk about scientific research. He should also talk about politics and principles!

But in Sun Yi's case, the so-called politics and principles are very simple, that is, to do well in one's own affairs and to show one's strong points.

However, the general environment makes Sun Yi's simple ideal lack the so-called sense of mission, so Sun Yi, who doesn't understand these things, becomes more and more unsuitable. At the same time, many people, including the person in charge of the Hangfa manufacturing plant, have read nothing about Sun Yi for so many years. What's the use of even poor interpersonal relations?

Under such circumstances, Sun Yi, who is physically and mentally exhausted, finally resigns and plans to go to the United States. Even if the United States is in trouble, at least he can be given a quiet place to do research.

As soon as Sun Yi left, his leading research on ceramic heat-resistant coating materials came to a standstill, and there was no way. Now the gap between domestic and international mainstream research on ceramic materials is quite large, so Sun Yi, who specializes in ceramic materials in Applied Materials Major of MIT, became an authority in this field as soon as he returned home.

Otherwise, the person in charge of the Hangfa manufacturing factory could not have come to the door to engage in cooperation. As a result, they made a good cooperation, and finally they made Sun Yi angry.

However, the person in charge of the Hangfa manufacturing plant and others didn't care much. After all, Sun Yi left behind a lot of things. Even if he stopped completely, he could extract one or two application technologies from the existing achievements and become the person in charge of the Hangfa manufacturing plant with rare achievements and experience.

However, Sun Yi, who should have gone to the United States, appeared in the pilot research center of Tengfei group, which surprised the person in charge of the manufacturer. But before the person in charge of the manufacturer digested the information, Sun Yi's next words were like a heavy hammer, which almost did not make the person in charge of the manufacturer vulnerable The little heart was broken.

"Now the No.1 and No.4 engines of tnb-19 aeroengine have been disassembled. Like wd-62mvp, the wd-66 turbofan with large bypass ratio is the core engine of our group's generation 2.5. This set of core engine has one feature, that is, the integrated design of combustion chamber and high-pressure turbine director. The advantage of this is that the high-temperature jet ejected from the combustion chamber When passing through the high-pressure turbine guide, the turbulent heat flow can be straightened out completely, so that the high-pressure turbine can be driven more efficiently. At the same time, the service life of the turbine can be improved, and the overhaul interval of the aero-engine can be greatly prolonged.

However, in order to do so, it is necessary to ensure that the guide vane on the high-pressure turbine guide can withstand the impact and burning of high temperature heat flow up to 1300 degrees Celsius, so high requirements are put forward for the blade.

For this reason, I put forward two technical routes: one is to spray ceramic heat-resistant coating on the outer layer of the original nickel based metal alloy guide vane, just like the high-pressure turbine guide vane of No. 4 engine; the other is to use ceramic matrix reinforced composite material as the guide vane, which is the recording route used by No. 1 engine.

Facts have proved that my second plan is obviously more effective than the first one. You can take a closer look at the two engines, and their flight time is about 120 hours. However, the guide vane on the high-temperature turbine guide of the No. 4 aircraft with ceramic heat-resistant coating has been damaged by naked eyes, so the status of the No. 4 aircraft is not stable. On the contrary, the No. 1 aircraft is unstable The new zbf-600 ceramic matrix material is still in good condition, and the thrust of the engine is always in good flight condition. "After listening to Professor Sun's remarks, the heads of a group of AVIC manufacturing plants, including the deputy director of AVIC, whirled several times between the No. 1 and No. 4 aircraft, and looked over and over again for dozens of times. It was confirmed that what Professor Sun said was true. There were indeed several defects on the blades of the high-pressure turbine guide on the No. 4 aircraft, although not obvious, which can be used in the aeroengine industry The secret product is really a great defect.

In contrast to the No. 4 machine, the No. 1 machine can't see any defect with naked eyes, even if it is measured with flaw detector.

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

At this time, I thought that the leaders of the aviation development manufacturing factory who had won the first place on their side fell into collective silence again. Then, including the deputy director, they all looked at the person in charge of the aviation development manufacturing factory who was hard with Zhuang Jianye.

"Ladies and gentlemen, our ceramic coating spraying technology is absolutely guaranteed. You know, all our spraying equipment is imported from Japan. The meticulous craftsmanship spirit is definitely not comparable to that of domestic products..."

"Well, my leader, you can imagine that the Japanese equipment is used to make a loss in aeroengine. Even they dare not use it in this way. Congratulations, the Japanese will definitely appreciate you. In this case, I'd like to ask you a favor..." The person in charge of the Hangfa manufacturing plant also wanted to force an explanation, but before he finished, he was interrupted by Zhuang Jianye with a smile. He immediately put a guide blade that he didn't know where to change into the hand of the person in front of him, and patted the other person's thick hand: "take this guide blade to the Japanese, and see if they can use the Japanese craftsmanship spirit of hanging hair to do it for Laozi intact Come out
