Chapter 1221: They can’t grasp the depth of the water that alternately turns cold and hot
Although Bodi’s reasoning process has nothing to do with the actual situation, it does sound very reasonable.
And it also satisfies all the British stereotypes about France, Germany and China.
The emotional value is full.
The most important thing is that Bodi has indeed worked in front-line technical positions for a long enough time and is almost a walking industry database.
Therefore, even though this conclusion sounds a bit outrageous at first, Panos Watson still believes it by six or seven points.
“So, Tim, do you think the Chinese are serious?”
His tone seemed to have not changed, but his speaking speed was much faster than before:
< br>"I mean, regarding the new emission standards...you should have seen the email I sent, right?"
Just as Watson finished speaking, Bo Dee's computer showed that a new encrypted email had been received.
After opening it, it was exactly the calculation result that the other party mentioned just now.
Although there were only a few simple tables, the contents still made the latter's heart sink.
In terms of concentration indicators of three typical exhaust gas components, it is already far ahead of the two benchmarks in the same level: V2500 and CFM56-7B.
Even worse than the NGME project that is still in the project demonstration stage.
It is only one step away from the standards proposed by the Chinese themselves.
Considering that the other party is unlikely to use other unpopular technologies at the same time, there is a high probability that it has only achieved this level by improving cycle efficiency...
It is not difficult to estimate that the corresponding fuel economy will also make a leap.
On the order of 20%.
You must know that the previous requirements given by Airbus were only to reduce fuel consumption by 15% based on the V2500.
Compared to environmental issues that no one really cares about, this is a real killer move.
"Yes, I'm watching..."
Bodi's voice was a little dry.
He knew that at times like this, he had to be more cautious when speaking.
Maybe just one sentence will affect the company's development route for the next ten to twenty years.
Therefore, Bodi did not give a frivolous judgment of "x is reliable" as he did just now, but patiently explained:
"Judging from their actions in developing new aero engines and some clues I observed here, the Chinese people are indeed determined to enter the mainstream aviation power market."
If it is When Watson heard this sentence two years ago, Watson's first reaction was definitely to sneer -
The mainstream aviation market is not just a small business jet or a regional jet. How can it be so easy? Got in?
After the disintegration of the Soviet Union, Russia worked hard for more than ten years, but barely reached the edge of this system.
Even France, as a member of the Western world, concentrated the power of almost all of Europe to get such an excellent trump card as Airbus, and then gradually became one of them.
Not to mention China, which started later and has a weaker foundation.
But the past of the Trent 900 is really too painful to look back on, and the fact that the French have been eyeing it across the English Channel has made Watson much more stable today.
He did not comment on this staged conclusion, but simply said:
"Go on."
The old superior, who had a strong desire to express himself, did not This was a sharp comment, which obviously surprised Bodie.
After a few seconds, he continued:
“But China told me that they planned to activate that standard in 2008. Of course, this time point refers to model registration and data submission, not Officially put into use. So according to the rules, there should be a buffer period of about two years, which will probably correspond to the mandatory rule coming into effect around 2010. "I am not sure whether this time is accurate, because he The compressor we are testing still seems to be in a relatively early stage, and it is currently unknown whether the model being tested uses the same intercooled heat recovery technology, and how much upgrades this technology can bring. Potential..."
"..."
The implication of these words is that there is currently too little information available. I will only list the parts that can be determined. Finally, please Lead your own judgment.
"Is it possible to ask sideways?"
Watson asked tentatively.
Bodi on the other end of the phone rolled his eyes, wondering just now who was worried that I would leave clues and be detained by the Chinese?
Now you are just using me as a consumable? "I'm afraid not."
So he immediately refused:
"Don't forget, we stole this information... uh... obtained it through special channels. If we ask the Chinese people directly, what is the difference between directly surrendering?"
Although his level is slightly lower than that of the other party, he has now entered the ranks of senior executives and is the leader of a key project team, not a direct subordinate.
There is no need to obey everything.
"Okay..."
Watson originally just asked casually, but after being directly denied, he did not continue to insist:
“In short, continue to maintain active contact with China. In addition, we can also provide the general needs and situation of the NGME project. Disclose this information about future market potential to China and see what kind of reaction the other party will give..."
This decision is somewhat irrelevant, basically equivalent to doing nothing.
Of course from another aspect, if you don’t do it, you won’t go wrong.
So although Bodi was a little disappointed, facing such a sudden scene, he couldn't find any better countermeasures for a while, so he had to express his agreement.
...
The other side.
After ending the call with Bodie, Watson only hesitated for a short time before picking up the phone receiver again:
"Ms. Roebuck, please help me contact Germany. branch, ask them to contact MTU to see if they can obtain the specific information of the CLEAN plan that year. "
"The reason... Let's just say that we are looking for partners to jointly develop a new generation of aerospace engines with revolutionary technology. The Germans have been wanting to use their advantages in the gas turbine field to enter since the 1990s. In the field of aviation development, this opportunity should not be missed..."
"..."
After putting down the phone again, Watson leaned his upper body heavily back on the back of the office chair, and then sighed softly.
In fact, Rolls-Royce has considered acquiring Tognum, the parent company of MTU Engine Company, since a few years ago, but has never been able to find a suitable opportunity.
If MTU could be successfully brought under its control back then, the current situation would obviously be much clearer.
At this time, an old man with a white beard on the sofa spoke:
"What did Director Purdy say?"
It was Richard Partridge.
“He believes that the Chinese people may have inherited some of the technical achievements of the CLEAN program, so they have applied the intercooling recuperation technology to the aero-engine field, so the exhaust emission characteristics will be closer to your MT30.”
Watson He replied:
"But we are not directly involved in this plan... The French's current position is rather suspicious, and the Swedes are just doing some side projects, so I just called to prepare to find out from MTU. Some situations..."
The two belong to different business sectors, and there is no direct conflict of interest between them. Instead, they have a lot of cooperation, so there is nothing worth hiding.
Unexpectedly, Partridge showed a serious expression after hearing this:
"CLEAN plan...is the one under the EU FP5 framework?"
It was just half Watson, who was lying down, sat upright instantly:
“You know?”
Partridge nodded:
"Under the FP6 framework starting next year, there is a NEWAC plan, which is an aero engine concept using an intercooled core machine..."
Watson's head was suddenly full. Question mark:
“But...”
What he wanted to ask was that although he had just been promoted to management, he had worked in the aviation industry for more than 20 years before. Why haven't you heard of this at all?
But before he finished speaking, he was interrupted by the other party raising his hand:
“It was said to be researching aero-engines, but due to technical problems, everyone is actually using this shell to do other research... For example, MTU is actually We are developing tube bundle regenerators for their tank gas engines, and we are also preparing to implement the results in marine gas turbines, so your aviation development department was not responsible for this from the beginning.”
Watson. a while I didn’t bother to pursue these minutiae:
“So, it is very difficult to apply intercooling and reheating technology to aeroengines?”
“Podi said, The Chinese should have integrated the intercooler on the stator blades of the high-pressure compressor... From my point of view, although this will make the design of the compressor blades more difficult, it is not necessarily unfeasible..."
In terms of intercooling and reheating technology, Partridge is obviously more experienced:
“Take the intercooler as an example. The water droplets condensed out after the air passes through the intercooler will cause damage to the blades behind it. Severe corrosion, even if stainless steel is used to produce blades, the long-term impact of water particles on the blades may still cause rotational stall or even surge.”
“In marine gas turbines, this problem is solved by analyzing the moisture content of the air. The operating conditions of the intercooler can be adjusted at any time based on the changes in humidity after compression by the low-pressure compressor... However, the operating conditions of aeroengines are too complex, and an unimaginable scale of test data is required to set a cycle for each operating condition. Parameters, and once a problem occurs, the consequences will be more serious than that of a marine gas turbine..."
"..."
The core meaning is one sentence——
The water that alternates between cold and hot is very deep, and the Chinese people may not be able to grasp it.
