Military Heavy

Chapter 98

Glancing at Gilman who was in a sluggish state, Yang Fan said: "The meaning is very simple. I helped you find out the fault. In return, you must exchange things 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 do you want in return?"

Yang Fan said: "It's not that I personally want to be rewarded, but our LM2500 gas turbine is now a bare machine, once it starts to work, it will make a lot of noise, and we need an outer cover, which is a box in technical terms. "

Each LM2500 gas turbine has a box body, the main function is to isolate the noise, and it is convenient for the operator to observe closely.

"No, no, Yang, you should know that this item is not cheap. I cannot make such a decision. Besides, even if I report your request, the people above will not agree."

The packing body is really not cheap, it is not a simple cover, but something with relatively high technical content.

Since the packing body cannot be obtained, the next best thing is to fall back.

Yang Fan took a step back and said clearly: "There is no box body, and drawings are fine. We will make one ourselves according to the design drawings."

In fact, it is to make a copycat version.

Even if it is a counterfeit, it is better than nothing. The box of the counterfeit version can also play a huge role, and it is estimated that it has a function close to that of the original box.

In addition, this is a prototype, it doesn't need to be on the ship, and it doesn't usually run for a long time, and the copycat version is enough.

Gilman was about to say something, but Yang Fan waved his hand and interrupted, "I know that you keep the official design of the box body confidential, I don't want you to provide the official design, and you and Andrew will draw a design brief in these few days Drawings, indicating the main dimensions and main technical requirements, we can just make one based on your drawings.”

In fact, it is not impossible for Yang Fan to draw this blueprint by himself. Some main dimensions and the basic structure of the box are still clearly remembered.

Why bother drawing these drawings yourself when free labor is readily available.

Gilman hesitated for a moment.

With confidence in mind, Yang Fan told him: "It's okay if you don't draw us a blueprint, but you can find out the fault of this gas turbine yourself."

Finally, Gilman gritted his teeth and agreed, "OK, it's a deal. I'll draw up the drawings for the boxes and hand them over to you."

Hearing this, Yang Fan smiled happily.

The box body of this LM2500 gas turbine is available. Although it is a copycat version, it is also very good.

It is just a gas turbine used for teaching and training, and the requirements for the box body are not very high. When ordering it, in order to save money, the decision-makers did not even buy the box body, but a bare machine.

The conversation between Yang Fan and Gilman, some comrades around who understand English roughly, and those who do not understand English are very curious when they see Yang Fan suddenly smiling happily.

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

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

what!
Director Yang has already found out the fault, that's amazing!
There are really two brushes!

The two foreigners have been together since yesterday until today.

Our gas turbine will also have a box body in the future, instead of a bare machine.

Director Yang is really arrogant, let foreigners willingly work as coolies, helping to draw the blueprints of 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 for other people, and everyone would love to hear such words.

He raised his hand and pressed it down. After everyone quieted down, Yang Fan said loudly: "I speculate that there should be foreign objects in the attachment mechanism, and there is a slight jam, resulting in insufficient residual rotation."

It turns out that this is the reason.

Then, Yang Fan explained the cause of the failure to Gilman and Andrew in English, and the two had different reactions.

Gilman was taken aback, probably because he didn't expect this reason.

Andrew looked at Yang Fan contemptuously, and said directly: "It can't be the reason, you are too whimsical, how could there be foreign objects in our accessory mechanism."

Whether there are foreign objects, the facts speak for themselves.

Yang Fan beckoned to Gilman lightly, motioning him to put his ears on the accessory transmission mechanism, and then gently turned the blades of the gas stove.

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

The rotor of the gas turbine was gently driven by Yang Fan, and when he put his ear on the accessory transmission mechanism, Gilman's face changed again. He heard the "click" besides the normal sound of the gears turning. abnormal noise.

There is indeed a problem!
He is an expert in this field, and he knew the reason for this abnormal voice as soon as he heard it, and he looked at Yang Fan differently.

Awesome, so awesome!

We have been busy for so long. From yesterday to today, we have found nothing, and we have not been able to find out the reason. You discovered the problem so quickly.

Sensing Gilman's gaze, Yang Fan smiled, and then waved to Andrew: "Come here, you also come and listen."

Andrew walked over, imitating what Gilman did just now, and put his ears on the accessory drive mechanism, while Yang Fan gently turned the rotor of the gas turbine.

"click"

Andrew also heard this abnormal sound, and couldn't help but look at Yang Fan.

The problem has been found.

Yang Fan said loudly: "The problem lies in the transmission mechanism of this accessory. I guess there are foreign objects in it."

Gilman didn't say anything, but Andrew put forward a different opinion, "No, how could there be foreign matter in our gas turbine? Our strict inspection process will not cause the situation you mentioned."

Yang Fan smiled, but most of the smile contained a sense of ridicule.

Coax ghosts! ! !
At this time, I also told me about the strict testing process. I guess I think this is just a prototype for teaching and training. It may not even be tested before leaving the factory, or I just tried the car hastily.

If you don't believe me, just disassemble the accessory mechanism and check it.

Yang Fan said: "Mr. Gilman, I suggest you open the accessory transmission mechanism of this gas turbine and check it carefully."

Andrew was about to say something, but Gilman interrupted him with a wave of his hand. He knew that since the problem was in the drive mechanism of the accessory, he must take it apart and take a good look to see if there was a foreign object or other reasons.

"Andrew, go to work."

The boss said so, what else could Andrew say, so he had to pick up tools and start dismantling the accessory drive mechanism. The workload was not small, and Gilman was also helping.

Everyone watched the two foreigners work.

Chen Shaohua said: "Director Yang, there is really a foreign object inside."

Yang Fan said confidently: "Ninety-nine are inseparable, you will know after you take it apart."

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

Gilman turned these gears lightly, feeling the transmission of the gears with his hand, and watching them carefully.

Yang Fan said, "It's a flashlight for Mr. Gilman."

Soon, a flashlight was sent to Gilman. Under the light of the flashlight, he finally found a small piece of thin wire, about a few centimeters long.

Gilman is all too familiar with this type of fine wire, which is used to hold and lock nuts on LM2500 gas turbines.

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

Gilman nodded approvingly.

Anduru blushed, extremely ashamed.

This piece of wire should have been left out by his co-workers. If the upper management of the company knew about it, it would definitely be a big accident.

It's like a doctor operating on a patient and leaving the gauze in the patient's body carelessly.

　Thank you for your rewards, I haven't had time to make a list today, and I haven't had time to thank you one by one.
