Chapter 1063 It will take seven days
In fact, when Chang Haonan finished the first half of the sentence, everyone present was basically convinced.
After all, those who could reach the leadership position of the Aerospace Power Group in the early 21st century must have experienced various cooperation projects in the so-called "honeymoon period" in the 1980s, except for a few special circumstances.
So we all know a little bit about 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 the truth is not easy to refute -
As a model derived from a mature product, the Trent 900 has been uneventful for more than three years since the project was launched in 1999. As a result, you, China, got involved. Less than half a year later, one of them suddenly exploded without warning, and it happened to be the turbine part you were responsible for producing.
If you say it has nothing to do with you, who will believe it?
What's more, as a British company, there is no guarantee that Luoluo will not become a troublemaker and cast off its own responsibilities.
So, the only way to prove one's innocence is to join the investigation as Chang Haonan said.
This way you can at least take some initiative.
But before everyone could express their stance, the second half of his sentence was blocked by everyone...
Especially Zhu Linyu.
He adjusted his sitting posture almost subconsciously, leaning his upper body slightly forward in the direction of Chang Haonan:
"80% sure?"
In fact, in most cases, the statement "X is sure" is a casual reference.
As long as it is not 100%, it cannot be taken as true.
However, after all, Chang Haonan had a glorious history of identifying the problem with M88 from a distance before, so he really let Zhu Linyu ignore all the above problems:
"Can you tell me in detail?"
“Well...”
In fact, Chang Haonan himself was quite convinced, and it was only out of humility that he did not say anything.
But the basis of his judgment comes from the experience of his previous life after all.
Now I suddenly have to explain it, and I really have to organize some language.
After thinking for a few seconds, Chang Haonan continued:
"Actually, it's nothing special. Mr. Lin, who is in charge of business, should know that I asked Hao Hao to do it as early as the end of last year. China Development Group has reminded Rolls-Royce that the Trent 900's turbine has a design flaw, which can easily lead to over-rotation due to a sudden loss of load after the turbine shaft breaks."
He said and tapped the meeting report on the table:
“Although Rolls-Royce’s description of this accident is somewhat ambiguous, considering that the other party asked us to provide low-pressure turbine blades as soon as possible for accident recovery, , it is certain that this is the problem.”
“But as I just said, the prerequisite for causing over-rotation and causing the turbine blades to be thrown out is that the turbine shaft is broken, and such an outrageous problem of broken shaft cannot be solved in Trent. The relatively mature model of Da900 is most likely caused by external force. Combined with the abnormal temperature signal finally returned by the sensor, the inspection scope can be directly reduced to the accessory system outside the receiver, or to be more precise, the oil pipe On the road..."
"..."
Actually, Chang Haonan can be more precise.
The root cause of the QF32 accident in the previous life was that a short oil pipe installed on the medium and high pressure turbine bearing casing was not processed properly.
Under harsh external conditions and frequent driving and parking, this short pipe eventually broke, and the leaking 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 short oil pipes of 11 of them did not meet the requirements like the one that caused the accident. The processing and inspection records of the other 42 engines could not be found. .
In other words, this problem is not unique, it was just caught up by the unlucky Qantas.
On this current 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 in advance during the test.
To some extent, it can even be said to be a good thing -
It is better to explode on the test bench than to explode in the sky.
Of course, he can only recall these contents in his heart.
Defining a scope of investigation can be regarded as reasoning.
But to directly point out which part number the problem lies in is a bit of a trick.
Even now, the effect is already quite obvious.
Lin Zuoming, who had been hesitant just now, made a 180° turn and immediately expressed his agreement.
He even asked to personally serve as the leader of the investigation team.
But in the end, Zhu Linyu rejected it.
Firstly, we are currently in the critical stage of the reorganization of the Science and Technology Committee. As the de facto second-in-command of the Aerospace Power Group and the most likely successor to the first-in-command, it is really not suitable for him to go abroad casually.
Secondly...
Although Lin Zuoming is said to be in charge of technical work, he only knows a little more than several other deputy general managers who have completely non-technical backgrounds.
Essentially, I haven’t been responsible for specific research and development work in more than ten or twenty years.
If you really want to lead an investigation team, it will still be a layman commanding an expert.
Of course, this second reason is put more euphemistically.
But it still filled the conference room with a happy atmosphere...
In the end, Chang Haonan ended the matter:
"Mr. Lin, In fact, only one person can be the leader of this investigation team."
"Who?" Lin Zuoming was obviously still feeling regretful about losing an opportunity to show off.
"Ren Bingda, the deputy general manager of Haofa Group, is also the person in charge of the Chinese side of Xiluo Group."
Chang Haonan replied:
"Trent 900 The high and low pressure turbines are apparently produced by the Silo Group. Haofa only accepts subcontracting and is responsible for the OEM. Therefore, Rolls-Royce will not allow us to participate in the investigation in any case. Among them."
"Only Comrade Ren Bingda, by virtue of his position in the Ciro Group, is not so sensitive to the British, so he will have some room for maneuver..."
...
After a whole night of discussion and planning, the group headquarters finally sent a rough action plan and requirements to Haofa Group before going to work the next day.
Zhang Zhenhua and Ren Bingda also conveyed Chang Haonan's request to Tim Purdy.
The latter's initial reaction was probably almost the same as Chang Haonanhe's.
“This is impossible!”
Bodi showed an expression as if he had eaten a fly:
“At the contractual level, there is no direct relationship between your group and Rolls-Royce. If there are Chinese faces in the accident investigation team, We simply can’t explain it to the board of directors.”
Although it was he who proposed to Panos Watson that he could disclose the general circumstances of the accident to China 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. Purdy.”
Ren Bingda had a brilliant idea in his hand, so he was not panicked about it. He just smiled and pointed out the loopholes in the other party's logic:
"As you said yesterday, if the investigation does not produce results for a long time, then we will use the OEM to The fact that my identity is involved in the production of Trent 900 will be made public sooner or later, right?”
“Although this may indeed cause our reputation to be damaged, if it really happens, I’m afraid. Or will it be your group... or Mr. Bodi, your personal loss will be more serious?"
Bodi immediately froze on the spot.
The previous sentence was exactly the reason he gave yesterday when he persuaded Zhang Zhenhua to jump in line to arrange production.
As a result, after one night, it turned into a boomerang stuck in my back.
And what Ren Bingda said was exactly what he was most worried about.
Involving subcontracting at various levels in the production process can be a big or small matter.
If everything goes well, of course everyone is happy.
But if he really wants to go online, he, the deputy director, is undoubtedly the most likely position to be pulled out of the position to sacrifice to heaven.
But then again.
If the Chinese people participate in the investigation, then even if the results are found, he may still take the blame...
While heaven and man are at war in Bodi's mind, Ren Bingda is not worried. Slowly turned the notebook in front of him to the next page:
"Actually, Mr. Bodi, the size of our delegation does not need to be large, it only needs three to five people, and the members are headed by me. They are all staff of the Siro Group..."
The meaning of this sentence is obvious.
It just means that there will definitely be no loopholes in the procedure, eliminating the worry of Bodi being settled.
However, the latter’s suspicion is still not so easy to clear away:
“Three to five people?”
As far as an accident investigation team is concerned, even if there are only Even with limited participation, this scale is really too small.
“Uh...that’s right.”
In fact, Ren Bingda was a little confused about this number, but Mr. Chang emphasized repeatedly in the morning that scale is not important, as long as someone passes it, it will be considered a success, so he quickly nodded firmly and explained:
"Actually We also considered that the accident involved a product we produced. We must personally rule out the possibility of defects in the turbine blades before we can be considered responsible for the product for life. That's why our superiors asked us to be a witness, so it doesn't need to be too large. , and it will not interfere with your normal investigation work..."
"And only in this way can we have sufficient reason to suspend the current production tasks..."
"... ”
Verbally, you can naturally say a lot.
Anyway, as long as they can successfully intervene in the investigation, Luo Luo will not have the final say on what happens next.
What's more, Ren Bingda's promise was only not to "interfere" with the investigation.
I didn’t say it wouldn’t affect me——
I will give you the investigation results directly, so it doesn’t count as interference, right?
In short, after some language offensive, Bodi, who had already loosened his attitude, finally completely declined. He promised to report China's requirements and wait for the final decision of the project manager, but there is no guarantee. can be approved.
Although they say so, everyone knows that the so-called "waiting for superiors' decision" is just an excuse used as a buffer.
However, for the sake of safety, Zhang Zhenhua, who had been silent before, still added a one-hit kill:
"Mr. Bodi, I hope you can give feedback to your superiors. The investigation team will personally bring the turbine blades you ordered to the UK, and they will be available in about seven days at the earliest.”
