After looking at Gilman in a dull state, Yang Fan said: "The meaning is very simple. I will help you find the fault. In return, you must take out something and exchange it with us."

Now he understood.

It turns out that people don’t want to waste their efforts, but need rewards. This is very normal in a capitalist society, and Gilman doesn’t think it’s too much.

"Yang, what reward do you want?"

Yang Fan said: "It's not that I personally want to pay, but that our LM2500 gas turbine is now a bare metal. Once it is turned on, it will be very noisy. We need a cover, which is a box in professional terms."

Each LM2500 gas turbine has a box, and its main function is to isolate noise and facilitate operators to observe close to each other.

"No, no, Yang, you should know that this thing is not cheap. I can't make such a decision. In addition, even if I report your request, the people above will not agree."

The box is indeed not cheap. It is not a simple outer cover, but something with relatively high technical content.

Since you cannot obtain the box, you can settle for the second best.

Yang Fan took a step back and said clearly: "There is no box, but the drawings are fine. Let's make one by ourselves according to the design drawing."

In fact, it's just a copycat version.

Even if it is a copycat, it is much better than not. The copycat box can play a huge role, and it is probably close to the genuine boxcat box.

In addition, this is a prototype, and you don’t need to get on the ship, and you don’t have much time to run, so there is enough copycat version.

Gilman was about to say something, but Yang Fan waved his hand and interrupted, "I know that you are confidential in the formal design drawings of the box. I don't want you to provide formal design drawings. You and Andrew took the time to draw a simple design drawing in the past few days, indicating the main dimensions and main technical requirements. We can make one based on the drawings you have drawn."

In fact, it is not impossible to ask Yang Fan to draw this drawing by himself. Remember some of the main sizes, the basic structure of the box, etc. very clearly.

With free ready-made labor, why bother to draw these drawings yourself?

Gilman hesitated.

Yang Fan was confident and told him: "It's no problem not to draw drawings for us, so you can find the fault of this gas turbine yourself."

Finally, Gilman gritted his teeth and agreed, "OK, the deal is completed, I will draw the drawings of the box and hand them to your hands."

Upon hearing this, Yang Fan smiled happily.

The LM2500 gas turbine has a box. Although it is a copycat version, it is also very good.

It is just a gas turbine for teaching and training, and the requirements for the packing do not need to be very high. When I ordered it, in order to save money, the decision-making level did not even buy the packing dormitory, but a bare metal.

During the conversation between Yang Fan and Gilman, some comrades who were roughly aware of English listened to a rough discussion. Those who didn’t understand English suddenly smiled happily when they saw Yang Fan. They were very curious.

Chen Shaohua said: "Director Yang, what did you say to Gilman? It seems you are very happy."

Yang Fan smiled again and simply said the matter loudly in front of everyone. Suddenly, the whole scene became uneasy.

What!

Director Yang has found the fault, it’s so awesome!

There are really two brushes!

The two foreigners have been from yesterday to today.

Our gas turbine will also have a box in the future, rather than a bare metal.

Director Yang is so awesome. What about foreigners willingly working as a coolie and helping to draw the drawings for the box?

Everyone's words floated into Yang Fan's ears, and Yang Fan felt a sense of relief. It would probably be the same if it were others. Everyone likes to listen to such words.

He raised his hand and pressed it down. After everyone calmed down, Yang Fan said loudly: "I guess there should be foreign objects in the attachment mechanism, which had slight stagnation, causing insufficient rotation."

So that's the reason.

Then, Yang Fan told Jillman and Andrew in English about the cause of the failure, and the two responded differently.

Gilman was stunned, probably not expecting that this is the reason.

Andrew looked at Yang Fan with contempt and said directly: "It's impossible for this reason. You're so whimsical. How could there be foreign objects in our attachment organization?"

Are there any foreign objects? The facts speak.

Yang Fan waved Gilman gently, signaling him to put his ear on the attachment transmission mechanism, and then gently rotated the blades of the gas furnace.

It was quiet all around, and everyone looked at Yang Fan and Gilman.

The rotor of the gas turbine was gently driven by Yang Fan's pull, and put his ear on the accessory transmission mechanism, Gilman's face changed again. In addition to hearing the normal rotation of the gears, he also heard the "kick" sound.

Sure enough, there is a problem!

He is an expert in this field. When he heard this abnormal voice, he knew that the reason was here. His eyes looked at Yang Fan differently.

Awesome, so awesome!

We have been busy for so long, from yesterday to today, we have been finding nothing, and we can't find out the reason, and you have discovered the problem so quickly.

Feeling Gilman's gaze, Yang Fan smiled, then waved to Andrew, "Come here, listen too."

Andrew came over and stuck his ear to the accessory transmission mechanism as Gilman had just seen, while Yang Fan gently rotated the rotor of the gas turbine.

"KaKaKa..."

Andrew also heard this strange noise and couldn't help but look at Yang Fan.

The problem has been found.

Yang Fan said loudly: "The problem lies in this attachment transmission mechanism. I guess there is a foreign object inside."

Gilman didn't say anything, but Andrew made a different opinion, "No, how can our gas turbine have foreign objects? Our strict inspection process will not happen."

Yang Fan smiled, but the smile mostly had a slight sneer.

It's a joke!!!

At this time, I told me the strict inspection process. I guess I think this is just a prototype for teaching and training. Maybe I didn’t even have a factory test run, or I just tried the car casually.

Don't believe it, right? Just open the attachment mechanism and check it out.

Yang Fan said: "Mr. Gilman, I suggest you turn on the accessories transmission mechanism of this gas turbine and check it out."

What Andrew was about to say, Gilman interrupted, knowing that since the problem was in the attachment transmission mechanism, he must be taken apart and looked at it carefully. Is there a foreign object or other reasons?

"Andrew, work."

What else could Andrew say when his boss said this, so he had to pick up the tools and start to dismantle the attachment transmission mechanism. The workload was quite large, and Gilman also helped.

Everyone was watching the two foreigners work.

Chen Shaohua said: "Director Yang, there are really foreign objects here."

Yang Fan said confidently: "I'll definitely stay away from you, and you'll know after you've opened it."

After a while, the accessory transmission mechanism was finally disassembled, and the structure inside could be clearly seen, including the pair of gears.

Gilman gently rotated the gears, and watched seriously while feeling the transmission of the gears with his hands.

Yang Fan said: "Give Mr. Gilman a flashlight."

Soon, a flashlight was sent to Gilman's hand. Under the flashlight, a small piece of thin iron wire was finally found, about a few centimeters long.

This model of thin wire Gilman is very familiar with, which is used to fix and lock nuts on the LM2500 gas turbine.

Yang Fan also saw this small piece of thin iron wire and reminded: "The root cause is here. It is because of its existence that the gears will make a crackling sound, resulting in insufficient rotation of the gas turbine."

Gilman nodded in agreement.

Andur's face turned red and he was extremely ashamed.

This piece of wire should have been left out by his coworkers. If the company's upper-level company knows about it, it would definitely be a big accident.
Chapter completed!
