Chapter 1067 In-depth Cooperation
Ren Bingda’s words did not trigger the shock he imagined.
The conference room was filled with more...
Confusion.
On the one hand, according to other people's expectations, the so-called investigation team sent by China should be just a soy sauce.
Even if it works, it should be related to the turbine blades.
And the sudden sentence just now was completely beyond expectations.
On the other hand, I really don’t understand it.
People of Ren Bingda’s generation can’t help but speak Chinese with a dialect accent, let alone speak a foreign language.
As a result, there were some signs of silence in the conference room, which had just been agitated by Wilson's display.
Fortunately, Tim Bodi's response was faster:
"Uh... I'm sorry, but can I trouble you to say it again?"
When Ren Bingda saw this, he simply stopped worrying and He picked up the information in his hand again and knocked it on the table a few times:
"We have found some interesting results. Please prepare a projector for me."
At the beginning of the 21st century, conference rooms have not yet been completely occupied by multimedia equipment, especially some old-school technicians who still prefer traditional methods.
Therefore, his small request was quickly fulfilled.
Didn’t wait for anyone to invite, didn’t ask anyone.
Ren Bingda briefly recalled Chang Haonan's appearance when he held a meeting with them before, and then walked to the small room without any care, amidst dozens of looks of confusion, doubt, or expectation. Behind the podium.
Then, put a page of the information on the projector's shelf.
Looking at his confident look, even Wilson, who was a little dismissive just now, subconsciously corrected his expression at this time.
"Quickly, close the curtains!"
Podi turned around and whispered to the people closest to the window behind him.
As a few clattering sounds were heard, the things on the curtain gradually became clear.
It is a hand-drawn schematic diagram of a short hollow tube, as well as a series of detailed design and manufacturing parameters.
There is also a photo attached at the bottom.
Unfortunately it's a little blurry.
“Wait a minute, didn’t I say that before——”
Wilson’s face changed slightly.
But this time, he was stopped by Watson sitting in front with a wave of his hand.
"Mr. Ren, please continue."
Obviously, the so-called "cannot take pictures" should be just a restriction casually stated by the former himself.
This is not an official request from Luo Luo.
However, Ren Bingda still explained it very "intimately":
"Mr. Wilson, I think it is necessary to explain that this photo was not taken by us, but from a photo taken by us. Extracted from the panoramic photos taken by Zhang Guifang and enlarged."
At this time, Wilson was speechless.
Accident investigations usually involve tens of thousands of evidence collection and archive materials. Recently, all his energy has been focused on simulated restoration. It is normal for him to have no impression of part of one of the photos.
But it’s still a bit embarrassing to be pointed out in public.
Fortunately, Ren Bingda was too lazy to continue arguing with him at this time, and turned around and continued his performance:
“During the investigation, we found that a number was 33-1472. The short lubricating oil pipe installed on the medium and high pressure turbine bearing casing was designed to have a wall thickness of 0.91mm. However, after actual measurement, it was found that the inner hole and the outer wall were not concentric during processing, and the thickest part of the pipe wall was found in the final product. It’s 1.42mm, and the thinnest part is only... 0.35mm.”
Even, in order to prevent the people below from hearing it clearly, I even slowed down when I said this.
finally.
As expected.
When the number 0.35 was spoken.
The scene was in an uproar.
“How is this possible?”
Someone immediately raised questions.
With this reaction speed, Ren Bingda had reason to suspect that the other party didn't even have time to think, but was just too shocked to trigger a subconscious reaction.
However, this question was exactly what he wanted, so he answered patiently:
"Indeed, when we first discovered this situation, we couldn't believe it either."< br>
“After all, Rolls-Royce is a company that has strict requirements on products, so it would be a bit unbelievable that such a problem would occur.”
"Actually, we had discovered the anomaly in this short pipe two days ago, but in order to avoid misjudgment we did not announce it in advance. We spent another two days compiling a detailed report before finally determining that it was a manufacturing problem. Correct..."
Ren Bingda paused for emphasis before saying "strict requirements" and "unbelievable" -
Although the whole sentence seemed to express praise.
But based on the actual situation at hand, the actual meaning is obviously exactly the opposite.
For a while, Watson and Bodie's faces were like changing faces in a Sichuan opera, turning red and white.
As for Wilson...
When Ren Bingda first came to power, he still had a bit of dissatisfaction on his face.
Obviously, he has made a plan. No matter what the former says, he will have to fight with him. After all, accident investigation is a very rigorous matter, and it is not something you can just make casual assumptions about.
However, the dissatisfaction soon turned into an accident.
Then came shock.
In the end, it turned into a helpless smile.
This question is too intuitive, and there is really no argument...
As for other people, some are still immersed in disbelief, while some have already begun to consider responsibility (dumping) and responsibility (pot). problem.
However, as an outsider, Ren Bingda naturally does not need to care about this.
Still he didn't stop.
Instead, he replaced it with another piece of paper, then raised his hand and pressed it down in mid-air, indicating that he was not finished yet.
Then, he continued to add:
“According to the relevant parameters previously provided by your company to us, the operating temperature outside the high-pressure turbine bearing casing is approximately 370-400°C, which is much higher than The ignition point of the lubricating oil, so after the short tube ruptures, the lubricating oil exposed to high-temperature air quickly begins to burn, and the fire spreads to the outside of the entire bearing casing in a very short time..."
"..."< br>
"Although the fire point starts from the corresponding position of the high-pressure turbine, the temperature of the oil combustion is not high enough to threaten the interior of the high-pressure turbine with the highest heat resistance, including the medium-pressure turbine. Due to the use of nickel-based alloys, it can also continue to work for a period of time. , In the end, the low-pressure turbine shaft, which uses titanium alloy and has an operating temperature below 500°C, lost its strength and broke first. The low-pressure turbine was decoupled from the fan and lost its load."
Ren Bingda paused suddenly here, his eyes slowing down. Scanning the entire conference room in front of him:
"I think you all already know what's going to happen next..."
After finishing speaking, he still imitated the British manner, He bowed slightly in a very graceful manner.
The more humble he is, the more embarrassed Luo Luo will be.
"This is the entire process of the accident that we investigated and subsequently deduced."
"Of course, it is just a rough estimate. I hope it can bring you some help..."
Ren Bingda thought that this performance of less than ten minutes was quite exciting.
At least Mr. Chang has six points of skill.
However, the expressions of the people below are even more exciting——
Nearly three hundred people spent more than half a month searching.
The result is not as good as three people and five days.
Of course, having said that, the accident investigation was originally a matter of luck.
Maybe someone just saw a problematic one among tens of thousands of fragments.
But the problem found in the end was so low-level that there was no way to fix it.
The short tube is processed eccentrically, and the deviation is large enough to be visible to the naked eye.
No one noticed it, and it was even installed on the engine.
This cannot be called negligence, it is simply a crime!
Especially Watson.
At first he felt a little embarrassed, but after he calmed down a little, he was dripping with sweat.
Thanks this is a test machine.
If this kind of problem is found in test flight aircraft or even mass-produced aircraft delivered to customers...
It’s hard to say what will happen to the company, but as the project director, I’m afraid he won’t There is good fruit to eat.
Thinking of this, Watson couldn't help but stretch a few veins on his forehead.
If it weren’t for the fact that Ren Bingda was still on stage, I would have jumped up and started trolling people.
After taking several deep breaths, he finally managed to suppress his anger:
"Body, remember to check the supplier of this hose and who is responsible for the quality inspection..."
When he heard this, Ren Bingda, who was already preparing to step down, suddenly stopped sorting out the information:
“We have also checked the supplier.”
“It’s Kawasaki. Heavy industry.”
"..."
For a moment, Bodi felt that he seemed a bit redundant.
Why do you let others do everything?
"This is the complete report we compiled. Mr. Watson, please take a look."
Ren Bingda walked down the small podium and kindly placed a stack of documents in front of the other party.
The content was specially written in Chinese and English, which was obviously well prepared.
Watson sighed, and without even flipping through the report in front of him, he directly said to Ren Bingda:
He knew that since the other party came with the printed paper version, then It shows that there must be a backup.
From the time China asked to participate in the accident investigation to today, this set of smooth operations obviously cannot be just to show off to Luoluo.
Now that the matter has come to this, why not everyone be more open-minded.
"Mr. Ren, regarding the content of this report..."
Ren Bingda obviously also had the idea of a showdown:
"The content of the report can be directly added to your accident investigation results. However... there are two requirements. "
"The first is to deepen the cooperation in the Trent 900 project. At least the outer accessories of the receiver should be produced by us. "
"The second is... we must reflect our role in the investigation of this accident and the development and production of the Trent 900 in an intuitive way!"
