Chapter 1066 must reflect the role of China!

Hearing this answer, Ren Bingda instantly understood.

At least I thought I had realized it.

Half a year ago, when he had just taken over the turbine blade outsourcing task from Rolls-Royce, he had mentioned to Chang Haonan in a meeting that the companies responsible for producing the turbine shaft and turbine accessories of the Trent 900 engine were Ishikawajima-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 segment in the future.

But looking back now, I was probably expecting problems back then!

Following this line of thought, everything is connected.

After all, it was Chang Haonan who first discovered the Japanese companies' reputation crisis that year, and it was made a big deal through an accident during the testing of NH90.

And the plot of Trent 900 in front of us...

Isn't it exactly the same?

Considering that Chang Haonan had foresightedly emphasized to Rolls-Royce in writing last year the risk of over-rotation after a broken axle, and the circumstances of this accident were exactly the same...

reasonable.

Too reasonable.

"If Mr. Chang were faced with this situation, his next move would be..."

Ren Bingda began to try to think from another perspective, trying to simulate what he should do next in Chang Haonan's "plan".

It was not until his subordinates next to him called out to him twice that he was awakened from his brainstorm.

"Mr. Ren, this is irrefutable evidence. As long as we take it out, we can almost directly determine the cause of the accident. Can we..."

Obviously, after being depressed for several days, the former couldn't wait to show off his feelings.

But Ren Bingda, who almost jumped up just now, calmed down at this moment.

"Not in a hurry."

He raised his hand to stop the other party:

“As the saying goes, if you see one cockroach in your house, there could be a thousand hiding in the dark.”

"This short section of pipe can explain a lot of problems, but it cannot fully reflect the role we played. Moreover, it is unlikely that such an outrageous quality problem will only appear in this short section of a few centimeters."

"You and Xiao Jin should be busy for the next two days. Find the other parts of this short pipe and the lubricating oil parts of the entire medium- and high-pressure turbine shaft and analyze them one by one to see how many of them are obviously unqualified."

"Yes!"

The other party nodded immediately, but then turned curious:

"Then Mr. Ren, you..."

"I plan to rush out a report before the first technical meeting the day after tomorrow to shut the British up completely..."

Ren Bingda stood up again, straightened his work clothes and said...

……

Time quickly passed and two days passed.

According to the schedule, the first technical meeting after the simulation restoration begins 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.

The reaction of public opinion is secondary, but Airbus, which has been dragged down, is getting a little impatient.

Even the French could not accept that the negotiations were initiated by the other party and there was no progress in two weeks.

Moreover, rival Engine Alliance has sensed something is amiss and is stepping up its public relations efforts with Airbus.

If we continue to delay, it is hard to say what will happen.

It can be said that the results of this accident reconstruction will be directly related to the future and fate of the entire Trent 900 model.

The atmosphere in the conference room was so depressing that it made people feel it was difficult to breathe.

Panos Watson looked at his watch.

There are still twenty minutes left before the meeting officially starts.

"Have you contacted Wilson?"

He suppressed his irritability and turned his head to ask Tim Bodie next to him.

"I have contacted them, 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, and he didn't even have time to put his laptop into his bag. Instead, he held it in his hand with the lid open.

From his tired expression, it was impossible to tell whether the result was good or bad.

"Since Qiao is already here, let's start early..."

Bodie was also extremely anxious at this time. He quickly motioned Wilson to sit on the left side of Watson. Then he looked around subconsciously while preparing to announce the official start of the meeting.

But before he could utter the last word, he noticed that someone seemed to be missing in the meeting room.

The sudden stop of the sound naturally attracted the attention of others.

"Puddy?"

Watson looked at him puzzledly.

"Director, the Chinese representatives have not yet arrived. According to our previous regulations, the meeting cannot officially begin yet."

"Where are they?"

"When I contacted him before, he said he had already left the workshop. Now... he should still be on the way."

As a super large enterprise with a history of over a hundred years, Rolls-Royce's headquarters is nearly as large as a small or medium-sized town. It often takes a long time to travel from one area to another.

Watson had no choice but to take a deep breath and wait patiently.

"Those three guys aren't really useful anyway, so why don't we just get started?"

Someone soon suggested.

But Watson still maintained his sanity.

It is obviously not worth it to lay a landmine for the subsequent accident investigation just for these 20 minutes.

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, Bodi finally announced the start of the meeting.

"We have now completed the first phase of the accident simulation."

Wilson didn't even glance at Ren Bingda's direction. He opened the PPT and went straight to the point to introduce the current work progress:

"Thanks to the cooperation of Dr. Leah Lapworth, we were able to restore the entire working condition of the turbine from the abnormal temperature to the blade being thrown out by testing part of the data sent back by the sensor."

"It can be confirmed that the root cause of the accident has nothing to do with the turbine. The intermediate and low-pressure turbine shafts were broken by external force about 2.5 seconds after the temperature anomaly occurred, which led to the loss of fan load. The speed increased to twice the maximum allowable limit in the next 1 second. The titanium alloy low-pressure turbine disk with poor strength was the first to be unable to withstand the centrifugal force and exploded. The broken pieces then penetrated the casing and were thrown out of the engine, causing more serious secondary damage..."

I have to say that the British are really good at making PPTs.

As Wilson introduced, the 3D scene restoration projected on the screen kept changing. Even if a non-professional spectator sat here, he would probably be able to understand most of it.

"So... the first part that broke wasn't even the blade?"

Bodie was somewhat surprised by the result.

After all, intuitively, as the speed gradually increases, it seems that the thin and fragile blade root part should be the first to have problems.

"At least... that's how it looks like in the restored version."

Wilson answered while using 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 damage to the casing is a broken piece formed after the turbine disk breaks."

At this point, someone finally noticed Ren Bingda, who had been sitting in an inconspicuous place and never spoke.

After all, these two parts are produced in China.

But the latter was writing something in a notebook with his head down, and didn't seem to have any intention of interrupting.

And Wilson quickly moved on to the next part.

"Our next plan is."

He turned around and looked at his colleagues in front of him:

"We need to conduct at least three more sets of experiments to determine where this so-called 'external impact' came from, whether it was outside the casing, or in the high-pressure compressor and combustion chamber."

The atmosphere, which had just relaxed a little, instantly became tense again.

The turbine is fine, but that doesn't mean the core engine is fine.

There are two other parts after all.

Bodie's question is more long-term:

"Three sets of experiments...are there enough materials?"

"That's the problem."

Wilson replied:

"We can only make one set at the moment. The rest will have to wait for a new batch of turbine parts to arrive."

Bodie's hand holding the pen shook violently.

The entire conference room fell silent again.

Even without considering the delivery cycle, the three sets of experiments will take at least another half a month to complete.

There's no time left anyway.

Therefore, the order is crucial.

At this time, Ren Bingda finally spoke:

"The next batch of blades has been cleared for customs and will be delivered in about a week. It will not affect the progress of the investigation."

The sudden words immediately attracted everyone's attention.

Including Wilson.

"Besides, it may not be necessary to do three more experiments."

Ren Bingda said as he pulled out a document that was estimated to be about 50 to 60 pages thick from his briefcase:

"Our investigation team has found some very interesting evidence through comparisons over the past few days, so... we suggest starting from outside the casing, strictly speaking, from outside the casing of the high and low pressure turbine shafts..."
