At the airport.

This Yunbak plane was hit by a bird hitting the engine when landing at the airport in the morning and has been parked here quietly. Everyone in the airport, today's topic is almost all about this Yunbak plane.

"Old Shen, I really can't imagine that there is no big problem with the engine."

"Yes, I heard that the engine manufacturer is coming soon to repair the engine on site. I heard that after the repair, the engine can work normally again."

"That's amazing!"

Everyone's topics were almost all about this Yun-8k aircraft and the turbofan 16 engine. Many people even ran to the front of the engine curiously, looked up for a long time, and nodded while watching, with admiration on their faces.

Some people even gave thumbs up after reading it, and some people, shortly after reading it, came over and watched it again with relish, as if they were never tired of watching it.

In the afternoon.

A military helicopter flew over and got off the plane, not only several military personnel, but also three people wearing Tianfeng Technology Company's work clothes, which were technicians and technical workers sent by Tianfeng Technology Company.

These three people from Tianfeng Technology Company not only have unified work clothes, but also carry tool boxes, bringing new fan blades.

As the person in charge of the airport, the colonel immediately went up to meet him. After briefly introducing the situation to everyone, everyone and their group headed straight to the Yunbak plane.

The colonel asked with concern: "Do you want to remove the engine? We can send ground staff to cooperate."

In terms of Tianfeng Technology Company, the leader is a technician who looks in his thirties, wearing glasses, and looks gentle. Through the introduction just now, the colonel knew that this was the potter and the leader of Tianfeng Technology Company.

The potter waved his hand and said confidently: "No, just replace the engine fan blades on the plane."

Replace fan blades directly on the plane without removing the engine!

Around the surroundings, many people looked at the potter in surprise, then nodded one after another, thinking to themselves. Tianfeng Technology Company is really awesome and directly replaces the fan blades on the plane.

The potter said: "Xiao Zhao, go up first and remove the air inlet cover of the fan rotor."

The young Xiao Zhao, who was quick and skillful, climbed up. In just two or three minutes, he removed the air inlet cover in the center of the fan rotor, revealing the fan tray inside and the root of the fan blades. You can see the fan blade tenon installed in the fan tray at a glance.

"Xiao Li, bring the tools and remove the two damaged fan blades. Be careful not to damage other parts, especially the fan tray."

"Potter, I know that the fan rotor of this engine was assembled by me and my master. I am very familiar with it and there will be no problems, so you can rest assured."

After saying that, Xiao Li quickly removed the two damaged fan blades, and the two blades were slightly deformed by the bird. One of them had a relatively obvious pit.

Many people surrounded them and looked at the two leaves at close range. Someone said, "Potter. What material is your leaves? Why are they so strong that they are not broken."

The potter proudly said: "This is the wide-string hollow fan blade of titanium alloy. Take a look at it. How wide is this piece, it is wider than the palm of our adults."

"It turned out to be made of titanium alloy, no wonder." Many people next to them had a great enlightenment.

Someone also said: "Power, the leaves look so wide, so long, and so thick, they should be dead."

Hearing this, the potter smiled and said, "How is it possible? If the leaves are dead and sank, then it's amazing. The engine is dead and sank, so how can it fly?"

Seeing that everyone didn't believe it, the potter smiled and said, "I don't believe it, right? You should weigh the weight of the leaf and pay attention to it."

Many people around were already very curious and were about to come up boldly, pick up one of the leaves, and when they were holding them, they used all their strength to treat the leaves as something weighing dozens of kilograms.

The potter, Xiao Zhao, Xiao Li and others looked at each other and smiled.

"Oh, it's so light, I can't believe it, it's so amazing."

The man who picked up the fan blade immediately shouted in surprise, his face full of surprise. It was obviously very unbelievable. How could such a large blade be so light?

Immediately, many people came up and took the fan blades, and then they all looked amazing. When everyone from Tianfeng Technology saw this, everyone smiled happily.

When the colonel saw more and more people coming up, he immediately said loudly: "Everyone retreat a little and don't interfere with the potters' work."

The potter smiled and said, "Don't worry, wait until we finish our business and leave enough time for you. If you are interested, you can try again."

After saying that, the potter took out the snow-white non-woven fabric, dipped it in alcohol, and carefully wiped the two fan blades replaced by the two pieces, and then said, "Xiao Zhao, weigh the weight of these two pieces."

Xiao Zhao used the electronic scale brought by him to weigh the weight of the two fan blades, and then weighed the weight of the two new fan blades that he was about to replace.

Because it is a fan rotor, it rotates at high speed during operation and has extremely strict dynamic balance. If the dynamic balance is not up to standard, the fan rotor will vibrate relatively large, and correspondingly, the noise will be high, which will even affect the overall performance and service life of the engine.

Therefore, the new fan blades that have been replaced must be consistent in weight with the replaced fan blades.

This is a technical job. After weighing the blades, the potter personally opened the tool box, took a bag of balance blocks, held the balance blocks one by one, weighed them one by one, and selected the most suitable two pieces.

The whole scene was very quiet, and everyone watched the potters and others work seriously.

The weight of the replaced old blades and the replaced new blades must be consistent. What should I do if the weight is inconsistent?

There is a way. The engine design has long been considered, and the balance block is used to adjust the weight difference between the blades to ensure the consistency of the weight of the two blades, so as to ensure that the dynamic balance of the fan rotor is within a qualified range.

The potters have a very high level of professionalism, otherwise Li Tianfeng would not have sent potters to lead the team. Potteries in their thirties have the title of senior engineer and are one of the first technicians to join Tianfeng Technology Company.

Soon, the appropriate balance block was selected. The potter personally directed Xiao Zhao and Xiao Li. It took less than half an hour to complete the work, and the air intake cover in the center of the fan was finally installed.

The colonel said: "Potter, is that OK?"

The potter said: "It should be OK. Everyone retreats and try the engine and you will know."

Soon, there was no one around the plane. Everyone retreated from a distance, and the potter and others retreated far away, retreating to a safe distance. As for the two damaged fan blades that the potter replaced, someone had already helped the potter carry them.

These two leaves are naturally scrapped, but the potter will still bring these two leaves back to Tianfeng Technology Company.

When the engine started, the sound of the engine working came. When the potter heard the familiar sound, he knew that the engine was normal and very normal.

The engine continued to work for a few minutes, and the potter waved his hand and said, "Okay, there should be no problem. The crew can draw a conclusion when they come over."

Sure enough, the crew came over and reported the situation one by one. The instrument display was very normal. So the potter said: "Captain Chen, the engine is normal, and we can carry out all the next test flight projects. We will also return to Tianfeng Technology Company."

Commander Chen, the colonel, just now, when he introduced each other, the potter knew that the colonel's surname was Chen and a colonel leader.

Commander Chen said politely: "Potter, since you are here, I will leave tomorrow. I have already ordered the kitchen team to prepare supper."

The potter said: "Thank you, Captain Chen, there are still many things in our company, we have to go back today."

After saying that, the potter took Xiao Li and Xiao Zhao, holding the tool box and the two damaged leaves replaced, and boarded the helicopter.

Commander Chen and others watched the helicopter leave until the helicopter disappeared into the distant sky...

Tianfeng Technology Company.

Li Tianfeng was answering the call from Zhang Haiping. During the call, Zhang Haiping was full of joy. "Mr. Li, you are amazing. It only took six hours since the accident, and the fault was successfully eliminated. Our Yunbak can test flights normally again."

Li Tianfeng was also quite happy: "Director Zhang, I am also very happy that I can continue to conduct normal test flights. In addition, we have submitted relevant information about the production license application for the turbofan 16 engine. I also have to ask you to say hello to the relevant departments."

Zhang Haiping said cheerfully: "No problem, it's not just me, I think Minister Liu will greet you to the relevant departments. I think the production license of the turbofan 16 engine will come down soon, and it will be a green light all the way."

Li Tianfeng was very happy when he heard this. As Tianfeng Technology Company became more and more famous in China, and its development of excellent engines has gradually entered the horizons of many military tycoons, such as design and production license applications, it is much easier than before.

The two of them chatted happily on the phone for at least ten minutes. After hanging up the phone, Li Tianfeng said in his heart that Zhang Haiping is good, he can be regarded as a true friend of his own and worthy of close friends.

the next day.

This fan blade, which was hit by a bird and was damaged to a certain extent, was placed on Li Tianfeng's desk. Li Tianfeng picked up one of the blades and looked at them seriously.
