Chapter 1066 China’s Role Must Be Demonstrated!
After hearing this answer, Ren Bingda instantly understood.
At least I thought I had enlightened——
Six months ago, when he just took over the turbine blade manufacturing task from Rolls-Royce, he once told Chang Haonan at a meeting that the people responsible for producing Trent 900 engine turbine shafts and turbine accessories were Ishikawashima Harima. Heavy Industries, and Kawasaki Heavy Industries.
Ren Bingda clearly remembered that Chang Haonan's expression after hearing this was very intriguing.
But he didn't think much about it at the time. He just thought that the other party was considering how to replace the share of Japanese companies in this link in the future.
But looking back now, I think I might have anticipated that something would go wrong at that time!
Following this line of thinking, everything is already connected.
After all, Chang Haonan was the first to discover the word-of-mouth crisis among Japanese companies, and it was caused by an accident during the testing of NH90.
And the plot of the Trent 900 before us...
Isn't it exactly the same?
Considering that Chang Haonan had the foresight to emphasize to Rolls-Royce in writing last year the risk of over-rotation after a broken axle, the circumstances of this accident were exactly the same...
Reasonable.
Too reasonable.
"Then if Mr. Chang faces this situation, the next operation should be..."
Ren Bingda began to try to put himself in another person's shoes, trying to simulate what he should do next in Chang Haonan's "plan".
It wasn't until the subordinate next to him called out twice that he woke up from his brainstorm.
"Mr. Ren, this is absolutely irrefutable evidence. As long as you take it out, you can almost directly determine the cause of the accident. Can we..."
Obviously, after feeling aggrieved for several days, the former couldn't wait to feel proud.
But Ren Bingda, who almost jumped up just now, calmed down instead.
"There's no rush."
He raised his hand and stopped the other party:
"As the saying goes, if you see one cockroach in your house, there are probably a thousand more hiding in the shadows that you don't notice."
"There is only such a short piece of pipe now. Although it can indeed explain a lot of problems, it cannot fully reflect the role we play. Moreover, it is unlikely that such an outrageous quality problem will only appear in this small section of a few centimeters."
"You and Xiao Jin will be more busy in the next two days. Find out other parts of this short pipe and the lubricating oil part of the entire medium and high pressure turbine shaft and analyze them one by one to see how many obvious substandard problems there are. "
"yes!"
The other party nodded immediately, but then turned curious:
"Then Mr. Ren..."
"I'm going to produce a report before the first technical meeting the day after tomorrow, and completely block the mouths of the British..."
Ren Bingda stood up again, adjusted his work clothes and said...
…
Time came very quickly two days later.
According to the schedule, the first technical meeting after the start of the simulation restoration will be held this afternoon.
Almost everyone came to the conference room early, waiting for Wilson to appear——
It has been more than half a month since the accident occurred.
Public opinion's reaction was secondary, but Airbus, which had been being dragged along, was already a little unable to sit still.
Even the French cannot accept negotiations initiated by the other party, but with no progress in two weeks.
Moreover, rival Engine Alliance has also smelled something amiss and is stepping up public relations with Airbus.
It's hard to say what will happen if we continue to delay.
It can be said that the outcome of this accident restoration will be directly related to the future and destiny of the entire Trent 900 model.
The atmosphere in the conference room was so depressing that it made people feel breathless.
Panos Watson raised his hand and looked at his watch.
There are still twenty minutes left before the meeting officially starts.
"Have you contacted Wilson?"
He suppressed his irritability and tilted his head to ask Tim Purdy next to him.
"I contacted you and the testing center reported that..."
The latter was only halfway through his answer when he heard the sound of the conference room door being pushed open.
Everyone turned their heads in unison.
Wilson was standing at the door. He didn't even have time to put his laptop into his bag, but held it in his hand with the lid open.
From the tired expression on his face, it was impossible to tell whether the outcome was good or bad.
"Since Joe has arrived, let's start early..."
Purdy was also very anxious at this time, and quickly motioned for Wilson to sit on the left side of Watson, and then subconsciously looked around, preparing to announce the official start of the meeting.
But before the last word was spoken, he realized that someone seemed to be missing in the venue.
The sudden stop of the sound naturally attracted the attention of others.
"Purdie?"
Watson looked at him doubtfully.
"Director, the Chinese representatives haven't arrived yet. According to our previous regulations, the meeting cannot officially start yet."
"Where are they?"
"When I contacted him before, he said he had already left the workshop. Now... he should still be on his way."
As a very large enterprise with a century-old history, Rolls-Royce's headquarters is close to a small and medium-sized town, and it often takes a long time to get from one area to another.
Watson had no choice but to take a deep breath and continue to wait patiently.
"Anyway, those three people have no practical use, why don't we start first?"
Someone soon suggested.
But Watson still maintained his sanity after all.
It's obviously not worth it to spend 20 minutes laying a trail for the subsequent accident investigation.
Finally, five minutes before the meeting started, Ren Bingda strode into the conference room and found a place to sit slightly behind the conference table.
Almost at the same time, Bodie finally announced the start of the meeting.
"We have now completed the first phase of the accident simulation."
Without even glancing in Ren Bingda's direction, Wilson opened the PPT and went straight to the point to introduce the current work progress:
"Thanks to the cooperation of Dr. Lea Lapworth, we used part of the last data returned by the test sensor to restore the entire working conditions inside the turbine from the temperature abnormality to the blade being thrown out."
"It is completely certain that the root cause of the accident has nothing to do with the turbine. The medium-pressure and low-pressure turbine shafts were broken by external force about 2.5 seconds after the temperature abnormality occurred, which in turn led to the loss of fan load and the rotation speed in the next 1 second. Rising to twice the maximum allowable limit, the weak titanium alloy low-pressure turbine disc was the first to be unable to withstand the centrifugal force and exploded. The broken piece then penetrated the casing and was thrown out of the engine, causing more serious secondary damage..."
I have to say that the British are really good at making PPT.
With Wilson's introduction, the 3D scenes projected on the screen are constantly changing. Even a non-professional melon-eater sitting here will most likely be able to understand everything.
"So... the blade part wasn't even the first thing to break?"
Bodie was a little surprised by the result.
After all, according to intuition, when the speed gradually increases, it seems that the thin and fragile root part of the blade should be the first to have problems.
"At least...that's the restored situation."
Wilson answered while controlling the computer to enlarge one of the pictures:
"Unlike high-pressure and medium-pressure turbines, the most vulnerable part of the low-pressure turbine structure is the turbine disk. Even the first thing to cause damage to the casing is a broken block formed after the turbine disk is broken."
At this point, someone finally noticed Ren Bingda, who had been sitting in an inconspicuous place and had never spoken.
After all, these two parts are produced in China.
But the latter was lowering his head and recording something in his notebook, and seemed to have no intention of interrupting.
And Wilson quickly moved on to the next part.
"What's next is our plan."
As he spoke, he turned and looked at the colleagues in front of him:
"Conduct at least three more sets of experiments to determine where this so-called 'external force impact' comes from, whether it is outside the casing, or from the high-pressure compressor and combustion chamber."
The atmosphere that had just relaxed a little became tense again in an instant——
Just because there is no problem with the turbine does not mean that there is no problem with the core machine.
Then there are two other parts after all.
The problem Bodi thought of was more long-term:
"Three sets of experiments...are the materials still enough?"
"That's the problem."
Wilson replied:
"Currently there is only enough to make one set, and the remaining parts still need to wait for a new batch of turbine parts to be delivered."
Bodi's hand holding the pen shook violently.
The entire conference room became quiet again.
Even if the delivery cycle is not considered, the three sets of experiments will have to wait at least half a month to be completed.
It's too late anyway.
Therefore, the order is crucial.
But at this time, Ren Bingda finally spoke:
"The next batch of blades has been declared to customs and will be delivered in about a week. It will not affect the progress of the investigation."
A sudden sentence suddenly attracted all the attention.
Including Wilson.
"In addition, it may not actually be necessary to conduct three more experiments."
As he spoke, Ren Bingda took out a document that was about fifty or sixty pages thick from the briefcase he carried with him:
"Our investigation team has found some very interesting evidence through comparisons in the past few days, so... it is recommended to start from outside the casing, strictly speaking, from outside the casing of the high and low pressure turbine shaft parts..."
