Chapter 338: Replacement of Fan Blades

on the airport.

This Y-8K plane, which was hit by a bird when it landed at the airport in the morning, has been quietly parked here, and everyone in the entire airport, today's topic, is almost all about this Y-8K plane.

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

"Yes, I heard that the engine factory will come soon to repair the engine on the spot, and I heard that after the repair, the engine will work normally again."

"It's amazing!"

Everyone's topic almost revolves around this Yun-8K aircraft and the turbofan 16 engine, and many people ran to the front of the engine curiously, looked up for a long time, and nodded while watching, with admiration written on their faces.

Even, some people gave a thumbs up after reading it, and some people, not long after reading it, ran over to watch it again with relish, as if they never got tired of watching it.

In the afternoon.

A military helicopter flew over, and from the plane came not only a few military personnel, but also three people wearing Tianfeng Technology Company's work clothes, which were technicians and skilled workers sent by Tianfeng Technology Company.

The three people of Tianfeng Technology Company not only unified their work clothes, but also carried a toolbox and brought new fan blades.

As the person in charge of the airport, the colonel immediately greeted him, and after a brief introduction to the situation, everyone went straight to the Yun-8K plane.

The colonel asked with concern: "Do you want to disassemble the engine, we can send ground crew to cooperate." ”

Tianfeng Technology Company. The leader was a technician who looked to be in his thirties, wearing glasses and looking sven. Through the introduction just now, the colonel knew that this was the potter, the leader of the Tianfeng Technology Company.

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

Replace fan blades directly on the plane, without disassembling the engine!

Around. Many people looked at the potter in surprise, and then nodded their heads, thinking to themselves. Tianfeng Technology Company is really bullish, and directly replaces the fan blades on the plane.

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

The young Xiao Zhao is quick and skillful in his movements. Climb up. In just two or three minutes, the air intake hood in the center of the fan rotor was removed, revealing the fan tray inside, and also exposing the root of the fan blades, and the fan blade tenon installed in the tenon groove of the fan disc can be seen at a glance.

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

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

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

Beside him, many people gathered around and looked at the two blades up close, and one of them said: "Potter, what is the material of your blade, why is it so strong, and it hasn't been broken." ”

The potter said proudly: "This is a titanium alloy wide-chord hollow fan blade, you see, how wide this piece is, it is wider than the palm of one of our adults." ”

"It turned out to be made of titanium alloy, no wonder." Many people next to him came to their senses.

There are also humanitarians: "Potter, this leaf looks so wide, so long, so thick, it should be dead." ”

Hearing this, the potter smiled and said: "How is it possible, if the blade is dead and heavy, then it will be repaid, and the engine is not also dead and heavy, so how can it fly." ”

Seeing that everyone didn't believe it, the potter smiled and said, "Don't believe it, you weigh the weight of this leaf, and don't you value it." ”

Many people next to him were already very curious, and they were about to boldly come up, pick up one of the leaves, and when they took the leaves, they used enough strength to treat the leaves as something weighing dozens of catties.

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

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

The person who picked up the fan blade immediately shouted in surprise, with a look of surprise on his face, obviously very unbelievable, how could such a large blade be so light.

Immediately, a lot of people came up, took the fan blades, and then they were all amazed, and everyone from Tianfeng Technology, seeing this, everyone smiled happily.

When the colonel saw that there were more and more people coming up, he immediately said in a loud voice: "Stand out a little, and don't hinder the potters from their work." ”

The potter smiled, and then said, "Don't worry, when we finish our business, leave enough time for you, and if you are interested, you can try again." ”

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

Xiao Zhao used the electronic scale he brought to weigh the two fan blades, and then weighed out the weight of the two new fan blades that were about to be replaced.

Because it is a fan rotor, it rotates at high speed when working, and has an extremely strict dynamic balance, if the dynamic balance is unqualified, the vibration of the fan rotor will be relatively large, correspondingly, the noise will be large, and even the overall performance and service life of the engine will be affected.

Therefore, the weight of the new fan blade must be the same as that of the replaced fan blade.

This is a technical work, after the weight of the blades is weighed, the potter personally opens the toolbox, takes a bag of balance weights, holds a piece of balance weights, weighs them one by one, and selects the most suitable two.

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

The weight of the old blade and the new blade must be consistent, if the weight is inconsistent, what should I do?

There is a way to do this, and the design of the engine has long been taken into account, and the weight difference between the blades is adjusted with a balance weight to ensure that the weight of the two blades is consistent, so as to ensure that the dynamic balance of the fan rotor is within the qualified range.

The business level of the potters is very high, otherwise, Li Tianfeng would not send the potters to lead the team out, the potters in their thirties, but they have the title of senior engineer, and they are one of the first batch of technicians to join Tianfeng Technology Company.

Soon, the suitable balance weight was selected, and the potter personally commanded Xiao Zhao and Xiao Li, and it took less than half an hour before and after, and the work was completed, and the air intake cover in the center of the fan's rotation was finally installed.

The colonel said, "Potter, is it okay?" ”

The potter said: "It should be okay, everyone retreat, just try the engine." ”

Soon, there was no one around the plane, everyone retreated far away, the potter and others also retreated far away, retreating to a safe distance, as for the two damaged fan blades replaced by the potter, someone had already helped the potter hold it.

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

The engine started, and the sound of the engine working was heard, and the potter knew as soon as he heard this familiar sound that the engine was normal, very normal.

The engine continued to work for a few minutes, and the potter waved his hand and said, "It's okay, there should be no problem, the crew can come and draw conclusions." ”

Sure enough, the crew came over and reported the situation one by one, and the instrument display was very normal, so the potter said: "Captain Chen, the engine is normal, and we can carry out the next qiē test flight project, and we are also going to return to Tianfeng Technology Company." ”

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

Head Chen said politely: "Potter, since you are here, you will leave tomorrow, I have already instructed the cooking team to prepare dinner." ”

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

After speaking, the potter took Xiao Li and Xiao Zhao, holding the toolbox and the two damaged blades that had been replaced, and boarded the helicopter.

Regiment Commander Chen and others watched the helicopter leave until the helicopter disappeared into the sky in the distance......

Tianfeng Technology Company.

Li Tianfeng was answering the call from Zhang Haiping, and on the phone, Zhang Haiping was full of joy, "Mr. Li, you are really amazing, from the accident to the present, it has only been six hours before and after, and the fault will be eliminated smoothly, and our Yun-8K can test fly normally." ”

Li Tianfeng was also very happy: "Director Zhang, I am also very happy to be able to continue the normal test flight, in addition, regarding the application for the production license of the turbofan 16 engine, we have submitted the relevant information, and I have to trouble you to help me say hello to the relevant departments." ”

Zhang Haiping said briskly: "No problem, not only me, I think Minister Liu will help you greet the relevant departments, the production license of the turbofan 16 engine, I think it will come down soon, it will be a green light all the way." ”

Hearing this, Li Tianfeng is very happy, with the increasing fame of Tianfeng Technology Company in China, coupled with the development of an excellent engine, has gradually entered the field of vision of many military bigwigs, such as design finalization, production license and other application work, is also much easier than before.

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

The next day.

This piece of fan blades that were hit by a bird and had a certain amount of damage was placed on Li Tianfeng's desk, and Li Tianfeng picked up one of the blades and looked at it seriously.
