The military-industrial scientific research system of the academic master.

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

The atmosphere in the conference room was filled with more...

at a loss.

On the one hand, according to other people's expectations, the so-called investigation team sent by China should just be a bystander.

Even if it does play a role, it should be in aspects related to turbine blades.

But the sudden words just now were completely beyond my expectations.

On the other hand, I really didn’t understand it.

People of Ren Bingda's generation can't help but speak Chinese with a dialect accent, let alone foreign languages.

As a result, the meeting room, which had just been a little busy because of Wilson's presentation, actually showed signs of being a little cool.

Fortunately, Tim Purdy reacted quickly:

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

Seeing this, Ren Bingda simply stopped being anxious and picked up the documents in his hand again, tapping them lightly on the table a few times:

"We found some interesting results. Please prepare a projector for me."

At the beginning of the 21st century, conference rooms were not yet completely occupied by multimedia equipment, and some old-school technicians, in particular, still preferred traditional methods.

Therefore, his small request was quickly met.

I didn't wait for anyone to invite me, nor did I ask anyone.

Ren Bingda briefly recalled how Chang Haonan had given them a meeting before, and then walked to the back of the small podium amid dozens of confused, suspicious, or expectant eyes.

Then, he placed a page of the document on the projector's storage table.

Seeing his confident look, even Wilson, who had been a little disdainful just now, subconsciously straightened his expression.

"Quick, draw the curtains!"

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

With a few rustling sounds, the things on the screen gradually became clear.

It is a hand-drawn schematic diagram of a short hollow tube, along with a series of carefully labeled design and manufacturing parameters.

There is also a photo attached at the bottom.

Unfortunately it's a bit blurry.

"Wait, didn't I say before—"

Wilson's expression changed slightly.

But this time, Watson, who was sitting in front, stopped him with a wave of his hand.

"Mr. Ren, please continue."

Obviously, the so-called "no taking photos" should just be a restriction casually made up by the former.

This is not an official requirement of Rolls-Royce.

However, Ren Bingda still explained it very "considerately":

"Mr. Wilson, I think it is necessary to explain that this photo was not taken by us. It was extracted and enlarged from a panoramic photo taken by you."

Now Wilson was speechless.

Accident investigations involve tens of thousands of pieces of evidence and archival materials, and his recent energy has been focused on simulation and restoration. It is normal that he has no impression of part of one of the photos.

But it was still somewhat embarrassing to be pointed out in public.

Fortunately, Ren Bingda was too lazy to argue with him anymore, so he just 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. The wall thickness of the pipe was designed to be 0.91 mm, but after actual measurement, we found that the inner hole and the outer wall were not concentric during processing. The thickest part of the final product was 1.42 mm, and the thinnest part was only... 0.35 mm."

In order to prevent the people below from having trouble hearing him, he even slowed down his speech when he got to this point.

at last.

As expected.

When the number 0.35 was mentioned.

There was an uproar at the scene.

"How can this be?"

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 react subconsciously.

However, this question hit the mark, so he still answered patiently:

"Indeed, when we first discovered this, we couldn't believe it either."

"After all, Rolls-Royce is a company that has strict requirements for its products. It is a bit too incredible that such a problem occurred."

"In fact, we discovered the anomaly of this short pipe two days ago, but in order to avoid misjudgment, we did not disclose it in advance. It took us another two days to compile a detailed report, and finally confirmed that it was a manufacturing problem..."

Ren Bingda paused before saying "strict requirements" and "incredible" to emphasize that -

Even though the whole sentence seems to express praise.

But combined with the current actual situation, the actual meaning is obviously the opposite.

For a moment, Watson and Bodie's faces turned red and white like the face-changing in Sichuan Opera.

As for Wilson...

When Ren Bingda first came to power, there was still a bit of resentment on his face.

Obviously he had made up his mind to argue with the former no matter what he said.

After all, accident investigation is a very rigorous matter and you can't just make random guesses.

However, resentment soon turned into surprise.

Then came the shock.

Finally it turned into a helpless bitter smile.

This question is so straightforward, there is really no point in arguing...

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

However, as an outsider, Ren Bingda naturally doesn't need to care about these things.

He still 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:

"According to the relevant parameters your company provided to us previously, the operating temperature of the outer side of 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 ruptured, the lubricating oil that came into contact with the high-temperature air quickly began to burn, and the fire spread to the entire outer side of the bearing casing in a very short time..."

"..."

"Although the fire started at the corresponding position of the high-pressure turbine, the temperature of the burning lubricating oil was not enough to threaten the interior of the high-pressure turbine with the highest heat resistance level. The intermediate-pressure turbine, which was made of nickel-based alloy, could also continue to work for a period of time. In the end, the low-pressure turbine shaft, which was made of titanium alloy and had 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 suddenly paused here and slowly scanned the entire conference room in front of him:

"I think you all already know what's going to happen next..."

After he finished speaking, he bowed slightly and gracefully, imitating the British.

The more humble he is, the more embarrassed Luo Luo will be.

"This is the whole process of our investigation and subsequent deduction of the accident."

"Of course, this is just a rough estimate. I hope it can be of some help to you..."

Ren Bingda thought that the performance, which lasted less than ten minutes, was quite exciting.

At least he has acquired six points of Chang's skill.

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

Nearly three hundred people were involved in the painstaking investigation which took more than half a month.

The result was not as good as the other three people's five days.

Of course, accident investigation is a matter of luck.

Maybe someone just saw a problematic one among tens of thousands of fragments.

But the problems that were finally discovered were so low-level that there was no way to wash them away.

The short tube is processed eccentrically, and the deviation is so large that it is visible to the naked eye.

No one noticed it and an engine was installed.

This can't be called negligence, it's a crime!

Especially Watson.

At first he felt a little embarrassed, but after calming down a little, he was sweating profusely.

Thanks this is a test machine.

If this problem is found in test aircraft or even in mass-produced aircraft delivered to customers...

It’s hard to say what will happen to the company, but as the project manager, I’m afraid nothing will happen to him.

Thinking of this, Watson couldn't help but tense up a few veins on his forehead.

If it weren't for the fact that Ren Bingda was still on the stage, he would probably have jumped up and scolded him.

After taking several deep breaths, he finally managed to suppress his anger:

"Bodi, remember to check the supplier of this hose and who is responsible for the quality inspection..."

Upon hearing this, Ren Bingda, who was about to step down, immediately stopped sorting out the documents:

"We have also checked the supplier."

“It’s Kawasaki Heavy Industries.”

"..."

For a moment, Bodie felt that he seemed a little redundant.

Why do you let others do everything?

"This is the complete report we compiled. Please take a look at it, Mr. Watson."

Ren Bingda walked down from the small podium and kindly placed a stack of documents in his hand in front of the other party.

The content was specially written in both Chinese and English, and it was obviously prepared in advance.

Watson sighed, and without even flipping through the report in front of him, he spoke directly to Ren Bingda:

He knew that since the other party brought 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 smooth operation obviously cannot be done just to show off to Rolls-Royce.

Now that things have come to this, it would be better for everyone to be more open.

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

Ren Bingda was obviously also thinking of a showdown:

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

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

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