Chapter 1036 Warning From China

In the information age, news always travels faster than logistics.

George Brin and Adam Whittle are just two ruthless rubber stamp tool people. After determining that the documents provided by China had no obvious legal and technical risks, they took the first step to electronically copy them, and the current slightly shocking The project progress was submitted to the UK headquarters.

As for sample identification, technical testing, compliance review...

Stop making trouble, Ciro Company is just an empty shell with no three-digit employees in total, and most of them are scattered in various airports and warehouses...

It's impossible to do this.

Therefore, the British side, which is 8 hours different from China time, also received hundreds of materials from Ciro Company on the day of work on December 8.

Rolls-Royce's reaction to this...

Quite quickly.

The news was received at noon.

That night, before all the documents had even been printed out, prominent figures in the Trent 900 R&D team had already flown back from the UK and even various parts of Europe for meetings.

The one who was most irritated was obviously the person in charge of the process team, that is, the brilliant man who first proposed using the semi-finished product waste from China's research and development process to deduce the specific process of the other party, Nate McGill.

Because although he hasn’t seen what the finished product looks like yet, his plan has obviously collapsed——

Last time, about three months ago, the first batch of scrap products sent back by the Chinese were almost covered with various processing defects, such as cracks and remelted layers, which were only the most superficial ones. After further testing, it was found that The metallographic condition of the alloy also changed significantly.

Basically, it can be said that there is no progress at all.

Even after he took it back and analyzed it for a long time, he could only tell that it was processed with high-energy laser.

As for other features, and even specific parameters...

No need to think about it.

But at first, McGill even thought it was a good thing.

Because his idea is that the Chinese will need the third and fourth batches of raw materials for trial processing.

In this way, even if the other party deliberately destroys mechanically before returning it, they can gradually see the process of process improvement.

I can finally get some useful information.

As a result, once the second batch of raw materials passed, there was no news for three months——

In fact, it is not quite accurate to say this.

After all, China will still submit a progress report with standard format and beautiful writing every one or two weeks.

Unfortunately, these reports are very "British".

In other words, it’s huge but contains almost no substantive content.

Of course, everyone has worked their way up from a master's degree to a Ph.D., and they also know the hidden rules of filling periodic reports.

So gradually, no one took a closer look.

Just based on common sense, since the other party has never asked for the third batch of raw materials, it means that the progress may not be very optimistic.

However, just when everyone is relaxing and ready to enjoy the Christmas holiday.

But the Chinese just blew up a big one...

Until half an hour after the meeting started, McGill was still holding a page from the pile of reports, sitting at the conference table like a wooden man and looking at it——

On that page, printed are multi-angle pictures of production samples.

The air film hole has smooth edges and the material surface is bright.

There is even a slight reflection.

The previous battle-damaged style is completely invisible.

If the last time the Chinese delivered the RB211-524B4 sample, the result was directly delivered without a process, then this time at best they wrote an extra explanation to show respect for the person who asked the question...

So much so that for a moment, McGill even wanted to slam the table and angrily scold the Chinese for deliberately scrapping the first batch of raw materials just to make fun of him.

But then he recalled that he had vowed before that the other party could not see through this scheme, and finally he held it back...

…

Compared to McGill, whose white face had turned purple from suppressing his emotions, the others had a calm mind.

Lapworth's biggest hope is that the technology he developed can be used on the Trent 900. At this time, he is only one step away from realizing his dream. It doesn't matter who is specifically responsible for producing these turbine parts.

Bodi felt that this reverse engineering method was unreliable and a bit cheap from the beginning. Although the original intention was not particularly noble, looking at McGill's embarrassed look now, he could only feel happy.

As for other people, including project director Panos Watson, they originally had the attitude of playing three shots if there is no date.

Anyway, if you entrust the production of core components to others, the profits that should be lost and the secrets that should be leaked will be lost, so it is better to support McNair's plan.

What if it succeeds?

Without expectations, the defense will naturally not be broken.

but……

Do business with Huaxia, especially companies related to Chang Haonan.

If the defense is not broken here, it will always be broken elsewhere.

Just like now...

"Director Watson..."

Bodi suddenly raised his head, and his expression became serious:

"There's something important here."

He said, turning over some pages in his hand so that more people could see them.

However, the conference table is still a bit wide, and it is really difficult for people on the opposite side to see the densely packed English letters.

You can only see the word "WARNING" written in bold black font at the beginning.

I had no choice but to ask my secretary to find the electronic version of the manuscript.

In fact, at this point, no one thought much about it.

I think it is nothing more than some routine annotations made by Party B.

For example, pay attention to the operating essentials during clamping, installation and disassembly, and how to contact for repair or replacement of new parts in case of damage.

However, when the contents of that material were finally projected onto the screen, the contents surprised everyone.

"Warning about the possible lack of anti-overrotation design of the low-pressure turbine disk".

Obviously, this is not the kind of legal or rights clause that is added as a template, but an out-and-out technical document.

The content is also very simple.

Indicates that during the production process of turbine parts, we found that the Trent 900 engine lacks measures to prevent turbine overload and over-rotation in extreme circumstances. Once the turbine shaft breaks due to an accident or other reasons, more serious consequences may occur, and It is reasonable to speculate that your company may also lack the same type of design in the structure of the medium-pressure turbine.

However, considering that we have not obtained the complete design plan of this model, we have no way of knowing whether your company has achieved the same function with other technical means. Therefore, we are just here to make a kind reminder and hope that you will change it if it is, and if not, Jiamian and so on.

Even from an English perspective, the content seems a bit pointy.

As the person in charge of the entire model, Watson, not surprisingly, became famous because of this——

He has worked at Rolls-Royce for more than 30 years, and has designed more three-rotors with his own hands than the Chinese have ever seen on drawings. Your OEM may indeed have some special technical skills, but it is also honest. Now that I have completed my production orders, how can I guide myself on how to design an aero engine?

However, as a British gentleman, Watson would not directly start with an F word.

He took several deep breaths in succession, managed to calm down, and then said to Bodie:

"You write them a reply and say thank you for the reminder from our partners, but the Trent 900 is different from old aviation engines. Its turbine shaft has been precisely calculated during design and is responsible for the top craftsmanship and quality assurance teams. Production, there will be no breakage problem within the service life and non-external damage factors.”

"Furthermore, the Airbus A380 that the Trent 900 is installed on is a four-engine aircraft. Even if there is a very small probability that the engine is damaged due to external reasons, as long as one of the four engines can maintain operation, the emergency mode can be activated to maintain The plane will continue flying for at least half an hour..."

"..."

This reply can be considered a tit-for-tat response.

Generally speaking, the Trent 900 is different from the low-end gadgets you have come across in the past. Don’t think that just because you have learned Spey, you will understand our Rolls-Royce design philosophy. The concentric axis of the Trent series itself has a redundant design. An outrageous failure like a broken axis occurred inexplicably. If it was caused by external factors, then even adding an anti-overrotation design would be useless. Moreover, we also have a powerful mode that can ensure flight safety in the most extreme circumstances. You guys? It's okay if you don't know anything, but don't point fingers at us...

However, Watson did not write the whole truth.

In fact, from a pure risk control perspective, there is no drawback to adding an additional safety redundancy, no matter how flawless the design of the shaft itself is.

What really made them get rid of this design was the relatively complex structure of the three-rotor itself.

It’s not that it can’t be designed, but the cost control requirements given above are relatively high.

In order to compete with GP7200, performance must be compared with every penny.

Then we can only make some discounts on redundant design.

After all, with the development of aviation technology, this has always been a major trend.

Just like in the past, only four-engine aircraft were allowed to fly across the ocean, and later three-engine and twin-engine aircraft were gradually liberalized.

Moreover, they did not cheat in their calculations and tests. Unless there are external factors, it is indeed impossible for the shaft to break.

In short, before the samples were sent to the UK, the two sides had already completed a secret war of words.

At this point in time, almost everyone thinks this is just part of the bickering between the leaders of both sides.

But these two exchanges of documents, many years later, have become a kind of lingering influence that affects the entire world...
