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

In fact, when Chang Haonan finished the first half of his sentence, everyone present was basically convinced.

After all, those who could achieve leadership positions in the Aviation Power Group in the early 21st century, except for very few special cases, must have experienced various cooperation projects during the so-called "honeymoon period" in the s.

So we all have some understanding of the nature of Western countries.

If the cause of the accident cannot be found out as soon as possible, even if Rolls-Royce does not take the initiative to add fuel to the fire, public opinion will eventually put the blame on China.

And it’s hard to refute the logic—

The Trent 900 is a model derived from a mature product. Since the project was launched in 1999, it has been smooth sailing for more than three years. However, less than half a year after your participation in the project, one of your engines suddenly exploded without any warning, and the engine that exploded happened to be the turbine part that you were responsible for producing.

You say it has nothing to do with you, who would believe you?

What's more, Rolls-Royce is a British company, so there is no guarantee that it will not act as a troublemaker and shirk its own responsibilities.

Therefore, the only way to prove his innocence is to join the investigation as Chang Haonan said.

This way, at least we can take some initiative.

But before anyone could express their opinions, the second half of his sentence was completely confusing to everyone...

Especially Zhu Linyu.

He almost subconsciously adjusted his sitting posture, leaning his upper body slightly forward towards Chang Haonan:

"Eighty percent sure?"

In fact, in most cases, the statement "X% sure" is just a vague statement made casually.

As long as it is not 100%, it cannot be taken seriously.

However, Chang Haonan had a glorious history of identifying the problems of M88 remotely, so Zhu Linyu really ignored all the above problems:

"Can you tell me more about it?"

"Um……"

In fact, Chang Haonan was already quite certain in his heart, but he did not say anything definite out of modesty.

But his judgment was based on his experience from his previous life.

Now that I suddenly have to explain it, I really have to organize my words.

After thinking for a few seconds, Chang Haonan continued:

"It's nothing special. Mr. Lin, who is in charge of business, should know that I asked Gaofa Group to remind Rolls-Royce at the end of last year that the turbine of the Trent 900 has a design flaw. After the turbine shaft breaks, it is easy to cause overspeed due to sudden loss of load."

He tapped the meeting report on the table:

"Although Rolls-Royce's description of the accident is somewhat ambiguous, considering that they asked us to provide low-pressure turbine blades as soon as possible for accident recovery, we can be sure that this is the problem."

"But as I just said, the prerequisite for overspeeding and then causing the turbine blades to be thrown out is that the turbine shaft is broken. Such an outrageous problem as a broken shaft is most likely caused by external forces on a relatively mature model like the Trent 900. Combined with the abnormal temperature signal sent back by the sensor, we can directly narrow the inspection scope to the accessory system outside the casing, or to be more precise, the fuel pipeline..."

"..."

In fact, Chang Haonan could be even more precise.

The root cause of the QF32 accident in the previous life was that a short lubricating oil pipe installed on the medium and high pressure turbine bearing casing was not properly processed.

Under harsh external conditions and frequent start-stop processes, the short pipe eventually broke, and the leaked lubricating oil caused a fire, which eventually caused the turbine shaft to lose strength and break.

Afterwards, Rolls-Royce inspected another 53 Trent 900 engines and found that the oil short pipes of 11 of them did not meet the requirements, just like the one that had the accident, and there were no processing and inspection records for the other 42 engines.

In other words, this problem is not an isolated case, it just happened to the unlucky Qantas.

Now, on this timeline, except that the supplier of high and low pressure turbines has been changed to China, other parts have not changed.

It is also normal to be induced early during the test.

To some extent, it can even be said to be a good thing.

It's better to explode on the test bench than in the sky.

Of course, he could only recall these contents in his mind.

Defining a scope of investigation can still be considered as inference.

But directly pointing out which part number the problem lies in seems a bit like fortune-telling.

Even now, the effect is already quite obvious.

Lin Zuoming, who had been hesitant just now, made a 180-degree turn and immediately expressed his agreement.

He even requested to personally lead the investigation team.

But in the end, it was rejected by Zhu Linyu.

Firstly, we are currently in a critical stage of the reorganization of the Science and Technology Commission. As the de facto second-in-command of the Aviation Power Group and the most likely successor to the top leader, it is not suitable for him to go abroad casually.

Second time...

Although Lin Zuoming is in charge of technical work, he only knows a little more than the other deputy general managers who have no technical background.

In essence, I haven't been responsible for specific research and development work for more than ten or twenty years.

If you really want to lead an investigation team, it would be like an amateur commanding professionals.

Of course, the second reason is more euphemistic.

But it still made the meeting room filled with a cheerful atmosphere...

In the end, it was Chang Haonan who brought the matter to an end:

"Boss Lin, actually, only one person can be the leader of this investigation team."

"Who?"

Lin Zuoming was obviously still regretting the loss of an opportunity to show off.

"Ren Bingda, deputy general manager of Gaofa Group, also serves as the head of the Chinese side of Xiluo Group."

Chang Haonan replied:

"The high and low pressure turbines of the Trent 900 are openly produced by the Xiluo Group. Gaofa is only responsible for the subcontracting. So no matter what, Rolls-Royce will not agree to our participation in the investigation openly."

"Only Comrade Ren Bingda, with his position in the Xiluo Group, is not so sensitive to the British, so there is a certain amount of room for maneuver..."

……

After a whole night of discussion and planning, the group headquarters finally sent a rough action plan and requirements to Gaofa Group before work the next day.

Zhang Zhenhua and Ren Bingda also conveyed Chang Haonan's request verbatim to Tim Bodie.

The latter's initial reaction was almost identical to Chang Haonan's.

"This is impossible!"

Bodi looked as if he had eaten a fly:

"At the contract level, there is no direct relationship between your group and Rolls-Royce. If Chinese faces appear in the accident investigation team, we will not be able to explain to the board of directors."

Although it was he who suggested to Panos Watson that the general circumstances of the accident could be revealed to China in order to urge the latter to deliver the next batch of turbine blades as soon as possible.

But the proposal definitely does not include involving the other party in the investigation.

"But Mr. Bodie."

Ren Bingda had a brilliant plan in hand, so he was not panicked at all. He just smiled and pointed out the loopholes in the other party's logic:

"As you said yesterday, if the investigation doesn't produce any results for a long time, then our participation in the production of the Trent 900 as a contract manufacturer will sooner or later be made public, right?"

"Although this may indeed damage our reputation, if I were to be honest, I'm afraid your group... or Mr. Bodi, your personal loss would be more serious, right?"

Bodie froze in place.

The previous sentence was exactly the reason he gave yesterday when he persuaded Zhang Zhenhua to join the team to arrange production.

As a result, after one night, it turned into a boomerang and stabbed himself in the back.

Moreover, what Ren Bingda said was exactly what he was most worried about.

Subcontracting at various levels during the production process can be a big deal or a small deal.

If everything goes well, everyone is happy.

But if things really get serious, he, as the deputy director, would undoubtedly be the position most likely to be dragged out and sacrificed.

But then again.

If the Chinese participated in the investigation, even if the results were found, he would still be blamed...

Just as Bodi was struggling with his conscience, Ren Bingda slowly turned the page in his notebook:

"In fact, Mr. Bodi, our delegation does not need to be very large. Three to five people are enough. Moreover, the members, headed by me, are all employees of the Xiluo Group..."

The meaning of this sentence is obvious.

It means that there will definitely be no procedural loopholes, eliminating any worries about Bodi being held accountable.

However, the latter's suspicion is not so easy to be cleared:

"Three to five people?"

For an accident investigation team to have even limited involvement, this size is really too small.

"Uh...that's right."

In fact, Ren Bingda was also a little puzzled by this number, but President Chang had repeatedly emphasized in the morning that scale was not important, and it was considered a success as long as someone went there, so he quickly nodded firmly and then explained:

"In fact, we also considered that the accident involved the products we produced. We must personally eliminate the possibility of defects in the turbine blades in order to be responsible for the products for life. That's why our superiors asked us to be witnesses. So it doesn't need to be too large-scale, and it won't interfere with your normal investigation work..."

"And only in this way can we have sufficient reason to suspend the current production tasks..."

"..."

Verbally, one can naturally speak in a very exaggerated way.

Anyway, as long as he can successfully intervene in the investigation, what happens next will not be entirely up to Luo Luo.

What's more, Ren Bingda's promise was only not to "interfere" with the investigation.

But I didn’t say it wouldn’t affect——

I'm just giving you the results of the investigation directly. It shouldn't be considered interference, right?

In short, after a verbal offensive, Bodi, whose attitude had already softened, finally surrendered completely. He promised to report China's request and wait for the final decision of the project manager, but there was no guarantee that it would be approved.

That being said, everyone knows that the so-called "waiting for the decision from superiors" is just an excuse to buffer the situation.

However, for the sake of safety, Zhang Zhenhua, who had been silent before, added a fatal blow:

"Mr. Bodi, I hope you can report to your superiors that our investigation team will personally bring the turbine blades you ordered to the UK. The fastest...it will arrive in about seven days."
