Chapter 1065 Mr. Chang has figured out everything
After receiving the turbine blades delivered by China, Wilson began to organize manpower to prepare for accident simulation restoration.
Of course, it is impossible to go to the test bed and blow up another Trent 900.
Even though Rolls-Royce has a big business, it is impossible for Rolls-Royce to survive this kind of play.
Instead, it is carried out in specialized laboratories.
The scope of the simulation is also limited to the timing, trajectory and destructive force of the blades being thrown out after the turbine over-rotates.
It is certainly impossible to directly find out the cause of the accident by this method, but it can at least prove whether the core machine of the Trent 900 itself has a fatal flaw.
In fact, this is exactly the core purpose of Wilson, or in other words, project director Panos Watson—
For Rolls-Royce, the top priority is to buy enough time for the Trent 900 and calm public opinion.
As long as it proves that the core aircraft is fine, Watson dares to let Bodi and Airbus restart negotiations.
At that time, all rumors will naturally subside.
As for the accident itself…
There are still more than two years between now and the planned first flight of the A380.
Even before air testing using the A340 platform, there is still a year.
As long as the problem does not involve the core machine, other problems can be corrected no matter what...right?
In short, even if it is not corrected, the problem can be delayed for one to two years.
It's all worth it.
It is precisely because of this that from the day of the next day, Ren Bingda keenly discovered that the number of people working with them in the assembly workshop had actually decreased compared with that in the early morning.
More importantly, Wilson himself, who had previously vowed to "come to me if you have anything to do", was nowhere to be found.
Although this is objectively more conducive to the next operation of the three people, he still cannot accept the feeling of being kept in the dark despite his multi-tasking skills.
The fundamental purpose of the group sending them here was not to solve the problem with Luo Luo's voluntary labor.
But take this opportunity to improve China's status in the international aviation industry.
Fortunately, for Ren Bingda's generation of Chinese technicians, being “left aside by foreigners” is a perfectly normal experience.
So he skillfully took advantage of the opportunity of asking someone to help compare the production documents, and made some insinuations to several British engineers around him.
At this time, I was shocked to learn that the accident simulation restoration had begun.
One of the young people who came with him immediately became furious when he heard about this incident and said that he must seek an explanation from Wilson.
However, he was stopped by Ren Bingda.
“Mr. Ren…”
His eyes were full of confusion.
“The King of Hell is easy to meet, but the devil is difficult to deal with. This Wilson is intentional. He makes us frequently stop what we are doing to look for him, and we are unable to devote ourselves to our work.”
Ren Bingda explained as he turned around and returned to the pile of broken parts.
“Then we can't just wait and see, right?”
The other party followed behind and asked:
“And I think this accident simulation will be very helpful for us to understand Rolls-Royce's engine design and testing process.”
At this time, another person who was calmer had already realized the new problem:
"But Mr. Ren, there are only three of us... Considering taking turns to take breaks, there are only two working at the same time most of the time. If one more person is assigned to participate in the accident simulation, wouldn't it mean that only one person is left here to complete the daily tasks? The mission assigned by the general manager?”
For a time, the situation seemed to be at an impasse.
Faced with this situation, Ren Bingda showed a confident smile:
“Of course it's impossible to just wait...”
"We have a general understanding of the situation here. Bodi will be here in a while. We have another meeting with Panos Watson, the general manager of the Trent 900 project, before noon. Then we will meet directly with Panos Watson. Just let him talk and explain these things clearly..."
It was only then that the other two people reacted.
Wilson is not the easy-going King of Hell as Ren Bingda said.
But a difficult little devil.
Ren Bingda took out a notebook from his pocket and slowly began to record the damage of the parts corresponding to each number. He continued writing while writing:
“As for the manpower issue... we don't need to participate in their entire reduction test. As long as we can participate in the technical meeting after the test, it can take up to about two hours a day. If you free up a little time, you can participate.”
“Of course, when we meet with Watson later, we still have to ask for full participation, so that it will be easier to negotiate later...”
Sure enough, everything was just as he expected.
As project directors, Watson and Purdy were unable to renege on their promises regardless of their image like Wilson.
After all, the previously reached agreement clearly stated that the Chinese delegation was allowed to participate in the investigation throughout the entire process.
If the latter is excluded from a key link such as accident simulation and restoration, then in the end even the investigation report will not be signed.
However, Wilson, who was temporarily called to the conference room, was obviously well prepared and also brought out the contents of the agreement.
Indicates that the accident restoration workflow involves the core parameters of the Trent 900 and the technical secrets of their test team, which is a part of the agreement that can be exempted.
After a stalemate, both sides had no choice but to take a step back.
Huaxia no longer insists on participating in the entire accident restoration process, but the final results report of the restoration and regularly held technical meetings must be conducted with the presence of at least one person from China Xia.
In addition, Ren Bingda and the others also obtained permission to directly access the external accessories of the turbine and its production materials.
Anyway, for Rolls-Royce, since the core turbine part is produced in China, there seems to be no need to cover up the things outside the casing. However, for the targeted Chinese investigation team, this seemingly subtle change can have a qualitative impact on work efficiency.
In the half day before this, every time they found a suspicious part, they had to find the British engineer nearby to compare it with the production documents.
But others also have their own tasks and are not specifically responsible for this.
I can only help in my free time.
Now that you can check it by yourself, it is equivalent to directly skipping the most time-consuming process in the middle.
Therefore, after taking turns to rest that afternoon, the progress of the remaining two people was an order of magnitude higher than before.
So much so that even Ren Bingda himself didn't expect it.
They found what they were looking for before Wilson completed the first stage of accident restoration...
On the morning of the third day, Ren Bingda, who was inspecting the turbine attachment group as usual, suddenly heard an excited but obviously deliberately suppressed voice:
“Mr. Ren, I seem to have found it!”
"Um?"
Ren Bingda stopped what he was doing and raised his head.
However, he was not as excited as the other party
First, this work is really boring and monotonous. After working for three consecutive days except for eating and sleeping, even Ren Bingda felt a little numb.
Secondly, he himself had discovered highly suspicious parts several times before. After comparing them excitedly, he found that either they were originally designed in this way, or they were obviously damaged by secondary damage.
They have nothing to do with the cause of the accident.
Hence, at the beginning, he actually didn't have much expectations.
Just as a routine, I came to the subordinate with my notebook and prepared to find the corresponding technical information according to the number for comparison.
This time, however, he didn't even wait to write down the part number.
Just look in the direction the other person is pointing.
He suddenly opened his eyes.
That is a short length of pipe.
Should be used to transport lubricating oil or fuel.
Due to the combustion and subsequent explosion, it has been somewhat deformed in the middle.
At a quick glance, it seems to be no different from hundreds or thousands of other similar wrecks.
However, if you look closely at the cross-section of this pipe, you will find it.
The thickness of its tube wall is inconsistent.
In other words, it is an eccentric tube.
Basically, such a design will only be made in some extremely special circumstances, or in situations where self-respect is required.
Turbine accessories for aircraft engines are obviously not included in this list.
In other words, this is almost impossible to be a design requirement.
There is a high probability that there is a problem during production!
In an instant, Ren Bingda felt ten years younger.
My legs no longer hurt, and my waist is no longer sore.
Standed up with a groan, resisting the dizziness caused by insufficient blood supply to the brain, and found the list of external accessories of the receiver and the production technical documents from the side.
After comparing them one by one, we quickly found the location of this short pipe—
High and medium pressure turbine bearing casings, oil delivery pipelines.
Unsurprisingly, in the design document, here is a uniform short pipe with a wall thickness of 0.91mm.
At the moment, although the two of them do not have precise measuring tools at hand, they can still see with the naked eye that the thinnest part is not even half a millimeter.
“What a coward…”
Looking at the production technical documents in front of him, the young man next to him felt emotional and even spoke in dialect:
“Mr. Ren... to be honest, I still can't believe it...”
Such quality problems that are so outrageous that they can be seen with the naked eye are simply unimaginable for someone like him who only started working in the mid-1990s.
However, it passed two inspections by the first-tier supplier and Rolls-Royce itself, and was installed on the Trent 900 for testing.
Ren Bingda next to him looked calm on the surface, but his slightly trembling hands clearly revealed his inner shock:
“It's really an oil pipe…”
Before this trip, Chang Haonan specifically asked to focus on turbine accessories, especially the fuel oil supply system.
Although he did as he was told, he was still a little bit murmuring in his heart.
After all, there are thousands of possibilities for externally causing shaft breakage, and it is difficult to smoothly deduce the real cause.
But now that the ironclad reality is before him, he cannot help but not believe it.
At this time, Ren Bingda suddenly remembered that he seemed to have talked about the turbine attachment with Chang Haonan half a year ago.
“Check again which supplier produces this part of the turbine accessories.”
There was a clicking sound of the mouse wheel next to him.
“It's...Kawasaki Heavy Industries.”
