Chapter 1067 Deep Cooperation

Ren Bingda's words did not trigger the shock he imagined.

The conference room was filled with more...

Confused.

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 that sudden sentence just now was completely beyond expectations.

On the other hand, I really didn’t quite 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, the conference room, which had been a little agitated because of Wilson's display just now, actually showed some signs of silence.

Fortunately, Tim Purdy responded quickly:

"Uh... I'm sorry, but could you please say it again?"

Seeing this, Ren Bingda simply stopped worrying. Instead, he picked up the information in his hand and knocked it gently on the table a few times:

"We found some interesting results, please get me a projector."

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 back of the small podium amidst dozens of looks of doubt, doubt, or expectation.

Then, he placed a page from the document on the projector's shelf.

Seeing his confident look, even Wilson, who had been a little dismissive just now, subconsciously corrected his expression at this time.

"Quick, close the curtains!"

Bodie turned around and whispered to the people behind him closest to the window.

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, didn't I say that before-"

Wilson's expression 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 Rolls-Royce.

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 was extracted from a panoramic photo taken by you and enlarged."

At this moment, 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 was still a bit embarrassing to have it pointed out in public.

Fortunately, Ren Bingda was too lazy to argue with him at this time, so he turned around and continued his performance:

“During our investigation, we found a short lubricating oil pipe numbered 33-1472 installed on the medium and high pressure turbine bearing casing. According to the design, the wall thickness of the pipe is 0.91mm. However, after actual measurement, it was found that no work was done during the processing. When the inner hole and outer wall are concentric, the thickest part of the final product’s tube wall is 1.42mm, while the thinnest part is only... 0.35mm.”

Even, in order to prevent the people below from hearing clearly, when he said this, he deliberately slowed down his speaking speed.

finally.

As expected.

When the number 0.35 is spoken.

There was an uproar at the scene.

"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, and 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."

"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 before saying "strict requirements" and "unbelievable" to emphasize——

Although the entire sentence seems to express praise.

But based on the actual situation at hand, the actual meaning is obviously exactly the opposite.

For a moment, Watson and Bodi'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.

It was obviously planned that no matter what the former said, he would have to strike a blow.

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.

Finally, it turned into a helpless smile.

This question is so intuitive that there is really no way to argue...

As for others, some are still immersed in disbelief, while others have already begun to consider the issue of responsibility.

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 to indicate 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 about 370-400°C, which is much higher than the ignition point of the lubricating oil. Therefore, after the short tube ruptures, the lubricating oil exposed to the high-temperature air will The oil quickly began to burn, and the fire spread to the entire outside of the bearing casing in a very short time..."

"..."

"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, and the low-pressure turbine and fan were decoupled and lost their load. "

Ren Bingda suddenly paused here, and his eyes slowly swept across the entire conference room in front of him:

"I think you all already know what happens next..."

After he finished speaking, he also imitated the British manner and bowed slightly in a very graceful manner.

The more humble he appears here, the more embarrassed Luo Luo will be.

"This is the entire process of our investigation and subsequent derivation of the accident."

"Of course, it's 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 he already has six points of Mr. Chang's skills.

However, the expressions of the people below were even more exciting——

Nearly three hundred people spent more than half a month searching.

The result is not as good as three people’s five days.

Of course, having said that, the accident investigation was originally a matter of luck.

Maybe someone just spotted 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 sweating profusely.

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 a project manager, he probably won't get any good results.

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, he 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..."

Upon hearing this, Ren Bingda, who was already preparing to step down, suddenly stopped sorting out information:

"We have also checked the supplier."

"It's Kawasaki Heavy Industries."

"..."

For a moment, Bodie 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 stepped down from the small podium and kindly put a pile of documents in his hand 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 turning over the report in front of him, he directly said to Ren Bingda:

He knew that since the other party came with a printed paper version, it meant that he must have kept a backup.

From China's request to participate in the accident investigation to today, this set of smooth operations obviously cannot be just to show off to Luoluo.

Now that things have come to this, why not everyone be more open-minded.

"Mr. Ren, regarding the content of this report..."

And Ren Bingda obviously also had the idea of ​​​​a showdown:

"The content of the report can be directly added to your accident investigation results, but... there are two requirements."

"The first is to deepen the cooperative relationship in the Trent 900 project. At least the external accessories of the receiver should be produced by us."

"Secondly... we must demonstrate our role in the investigation of this accident and the development and production of the Trent 900 in an intuitive way!"
