Chapter 1221: They can’t control the depth of the water that alternately turns cold and hot.


    Although Bodie''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.


    Full of emotional value.


    The most important thing is that Bodi has 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 didn''t seem to change, but his speaking speed was much faster than before:


    "I mean, regarding the new emission standards...you should have seen the email I sent, right?"


    Coincidentally, just as Watson finished speaking, Bodi''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 the 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 better than the NGME project that is still in the program 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 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 about 20%.


    You know, the previous requirement given by Airbus was 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..."


    Bodie''s voice was dry.


    He knew that at times like this, he had to be more careful with his words.


    Maybe a casual 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 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 he had heard this sentence two years ago, Watson''s first reaction would have been to sneer -


    The mainstream aviation market is not a small business jet or regional jet. How can it be so easy to enter?


    After the collapse of the Soviet Union, Russia worked hard for more than ten years, but barely reached the edge of this system.


    Even France, which is 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 comment sharply on this, which obviously surprised Bodi.


    After a few seconds, he continued:


    "But China told me that they plan to activate that standard in 2008. Of course, this time point refers to model registration and data submission, not formal put into use. So according to the rules, there should be a buffer period of about two years. It will probably become a mandatory requirement around 2010.”


    "I can''t be sure whether this time is accurate, because the compressor they are testing seems to be still in a relatively early stage, and there is no way to know whether the model being tested uses the same intercooled recuperation technology, and whether this How much upgrade potential can this technology bring..."


    “…”


    The implication of this statement is that there is currently too little information available. I will only list the parts that can be determined. In the end, I ask the leader to make your own judgment.


    "Is it possible to inquire sideways?"


    Watson asked tentatively.


    Bodi on the other end of the phone rolled his eyes and thought to himself, who was worrying that I would leave clues and be detained by the Chinese?


    Are you using me as a consumable now? "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 directly, what''s 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.


    "All right…"


    Watson originally just asked casually, but after being directly denied, he did not continue to insist:


    "In short, let''s continue to maintain active contact with the Chinese side. In addition, we can disclose the general needs, situation, and future market potential of the NGME project to the Chinese side to see what kind of reaction the other party will give..."


    This decision was somewhat inconsequential and basically amounted to doing nothing.


    Of course, from another perspective, if you don’t do it, you won’t go wrong.


    Therefore, although Bodi was a little disappointed, facing such an unexpected situation, 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 the German branch and ask them to contact MTU to see if they can get the specific situation of the CLEAN plan that year."


    "The reason... is 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 the aerospace industry since the 1990s. They should not miss this time Chance…"


    “…”


    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 Bodie say?"


    None other than Richard Partridge.


    "He believes that the Chinese people may have inherited some of the technical achievements of the CLEAN program, so they applied the intercooling and recuperation technology to the aero-engine field, so the exhaust emission characteristics will be closer to your MT30."


    Watson 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 work, so I just made a call to get some information from MTU..."


    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:


    "The CLEAN plan...is the one under the EU FP5 framework?"


    Watson, who had just half-lyed 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 filled with questions:


    "But…"


    What he wanted to ask was, although he had just been promoted to management, he had worked in the aviation industry for more than 20 years, so why had he never heard of this?


    But before he finished speaking, he was interrupted by the other party raising his hand:


    "It is said to be researching aero engines, but due to technical problems, everyone is actually using this shell to conduct other research... For example, MTU is actually developing tube bundle recuperators for their tank gas engines, and we are also preparing to share the results The implementation is on marine gas turbines, so it was not your aviation development department’s responsibility from the beginning.”


    Watson couldn''t care less about pursuing these minutiae at the moment:


    "So, it is very difficult to apply intercooled heat recovery technology to aero engines?"


    "Bodi said that 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 of the air after passing through the intercooler will seriously erode the blades behind it. Even if stainless steel is used to produce the blades, the long-term impact of water particles on the blades can cause rotational stall or even Possibility of surge.”


    "On marine gas turbines, this problem is to adjust the operating conditions of the intercooler at any time by analyzing the changes in humidity of the humid air after being compressed by the low-pressure compressor... However, the operating conditions of aeroengines are too complex and require unimaginable scale testing. Only with data can it be possible to set cycle parameters for each working condition, and once a problem occurs, the consequences will be more serious than for marine gas turbines..."


    “…”


    The core meaning is just one sentence -


    The water that alternates between cold and hot is very deep, and the Chinese people may not be able to grasp it.
