Chapter 1128 Airbus, aiming for the future (xdm asking for monthly votes)


    The two test pilots in the cockpit have been waiting for a long time with the car warmed up.


    After receiving the takeoff command, the captain immediately released the brake lever.


    Jin Xu in the cabin only felt a slight vibration, and then the plane began to accelerate.


    The A340 has long been criticized in terms of takeoff distance and climb speed due to its relatively low thrust-to-weight ratio.


    Fortunately, this aircraft is just a test platform, and its dead weight is dozens of tons lighter than that of passenger transport, so the experience is similar to that of the 737 and A320 that we often fly on.


    In fact, if the runway length limit is not taken into consideration, only one Trent 900 (equivalent to 2.5 CFM56-5C) is required to be fully turned on to propel this 200-ton aircraft to accelerate and take off.


    Therefore, the main functions of the other three engines are actually safety and trimming.


    After all, there is also a project to simulate a mid-air parking and then let the engine complete self-starting during the test.


    But we certainly can’t really make the aircraft powerless.


    Throughout the takeoff process, Jin Xu was staring at a screen not far away.


    What is shown above is the speed and load of the rotors of the No. 2 engine at all stages, including the fan.


    Until the climb reaches 8,500 meters and levels off, the entire curve appears to be quite smooth.


    There were only two significant fluctuations.


    The moment the plane raised its head, and when it climbed to about 2,500 meters and encountered a burst of violent irregular airflow -


    Considering the severity of the air intake distortion, the working stability of the Trent 900 is obviously relatively optimistic.


    As for more detailed data, we have to wait until it is implemented before analyzing it.


    "Slowly rise to 10,500 meters, adjust the rotation speed to 40%, and prepare to connect the RS325 and HC402 probes..."


    The test leader sitting not far away ordered methodically.


    Upon hearing this, Jin Xu quickly turned his attention to the other party, and at the same time took out a notebook from his pocket—


    After helping Rolls-Royce find out the cause of the accident, Aerodynamics Group''s position in the entire project also increased.


    Otherwise, how could a mere second-tier supplier have the opportunity to follow us for aerial testing?


    Originally, he even wanted to bring a camera and tape recorder.


    But this is indeed a bit too outrageous.


    In the end, the two parties reached a compromise plan that allowed him to move freely without affecting normal test work and flight safety, and use paper and pen to record.


    The RS325 and HC402 are carbon oxide and nitrogen oxide detection devices installed under the wings respectively, used to test the pollutant emissions of the engine at different speeds.


    It is also the most important thing that Jin Xu needs to understand during this trip.


    Chang Haonan plans to focus on ultra-low fuel consumption and ultra-low emissions to enter the international market for the AE1500. However, China did not actually have a particularly complete aviation emission test standard before.


    And since this model is preparing to obtain EASA certification in the future, it is obviously a good choice to take this opportunity to refer to the process of Trent 900...


    …


    At this time, the aircraft had climbed to an altitude of nearly 10,000 meters. It was impossible to directly see the flight conditions from the ground, so Champine and Bodi found a place with a bright sun and waited for the first flight test to be completed. .


    Not long after he relaxed, the former saw a somewhat familiar face walking quickly in his direction.


    "Hello, Director Champine!"


    The visitor took the initiative to come forward and said hello to him.


    Only then did Champine remember that a Falcon 2000 business jet seemed to have landed before the 341 test platform took off.


    But at that time, his focus was all on the engine, and he didn''t care about the plane.


    Now that I think about it, it should be a charter flight from Dassault Group.


    "Dr. Casore, long time no see."


    Champine also shook hands with the other person warmly.


    The aviation industry group in Toulouse may seem quite large, but in fact most places are airports.


    The area really used for office and scientific research is not very big.


    The two of them are both senior executives of France''s core aviation companies, and it can be said that they see each other without looking up.


    We have known each other many years ago.


    As the management of Rolls-Royce, Bodi actually has little dealings with Dassault, which mainly deals in fighter jets and business jets.


    For Kasore, at most I have heard the name, but certainly not as acquaintance.


    So he originally wanted to find a reason to avoid it, and he could also take advantage of this time to take a nap.


    However, just as he turned around to leave, he heard Champine continue:


    "The last time I saw you was before Christmas last year... I heard that you went on a business trip to China?"


    For Casore, the cooperation between Dassault and China was no secret at all, so he answered almost without thinking:


    "Yes, there is a cooperation project there, so I have been staying here until now... I came back because of an urgent mission."


    But the speaker has no intention, and the listener has the intention. Bodi, who was still a little tired, stopped feeling sleepy in an instant and stopped immediately.


    He is now very curious about all companies that cooperate with China.


    Of course, we are not the same company...or even from the same country, so Bodi will not ask others for details of cooperation.


    I just took advantage of an opportunity to introduce myself:


    "Hello, I''m Tim Purdy, Deputy Director of Projects at Rolls-Royce. Nice to meet you."


    “…”


    It was a normal topic, so Kasore didn''t take it too seriously and just continued chatting with the two about harmless topics.


    But Bodi came with a purpose in mind, so naturally he couldn''t stay here doing oral gymnastics with him all the time.


    So after some pleasantries, he had no choice but to choose a slightly more radical approach:


    "Dr. Casore, I thought I heard just now that you just came back from China?"


    The latter has a background in military aircraft, so he is so sensitive.


    I instantly realized that the other person’s change of topic was a bit abrupt and there must be a pitfall behind it.


    Dassault has a cooperative relationship with China, which is almost a public matter.


    But the specific details of cooperation cannot be disclosed casually.


    So, he nodded:


    "Yeah, go over there and purchase some secondary aviation materials... You know, these things are not very demanding, and there is a cost advantage over there."


    Hearing that the other party was also looking for Chinese people as secondary suppliers, Bodi was slightly relieved:


    "really…"


    He nodded and continued:


    "To be honest, they have developed rapidly in recent years, but it is a pity that there is no market suitable for our Rolls-Royce..."


    As the deputy director of research and development of the Trent 900, when Bodi said there was no market, he naturally meant that there was no aircraft in China using Rolls-Royce engines.


    In fact, this was completely unintentional and just ended the topic about China.


    But Champine next to him obviously got the wrong idea. After hearing these words, he lowered his head, looking thoughtful.


    Until Bodi left, he was still a little bit distracted.


    "Tim."


    After a period of silence, Champion suddenly raised his head and looked at Bodi:


    "I wonder if you have any plans to develop a new engine with a thrust of about 12-14 tons, suitable for short- and medium-range passenger aircraft?"


    This sudden question made the latter a little confused. After thinking about it for a while, he asked:


    "You mean...for passenger aircraft like A320 and 737?"


    "right."


    Bodi''s expression became even more confused:


    "But...we already have the V2500 series?"


    Strictly speaking, the V2500 engine is a model developed and produced by International Aero Engines (IAE).


    Similar to the Engine Alliance Company that developed the GP7200, it is also for this dish of vinegar-wrapped dumplings.


    The company is a joint venture between Pratt & Whitney, Rolls-Royce, MTU, Fiat and Japan Aerospace Engineering Corporation. Its only product is the V2500.


    Although this means that there will be many companies to take a share of the pie, but judging from Rolls-Royce''s business distribution, it is obviously impossible to independently develop a product with duplicate positioning.


    But Champine shook his head mysteriously, came closer and lowered his voice:


    "We are planning a new generation of A320 passenger aircraft for 2010 and beyond. The core goal is to reduce fuel consumption by 15% and carbon and nitrogen oxide emissions by more than 20%... The V2500 is based on thirty years ago and cannot meet the requirements in any case. requirements, so a new motivation must be needed..."


    Bodie''s eyes shot open.


    This is incredible news.


    The 80-ton mainline passenger aircraft is conservatively estimated to be a trillion-dollar market.


    Any piece of cake here can affect the pattern of the world aviation industry.


    When the V2500 was determined to be eliminated early, Rolls-Royce had no experience in developing engines of the same level.


    If you don’t get the news today, you will definitely fall behind the two main competitors in the future:


    "I''m afraid I have to report this to the board of directors after I go back..."


    Champin nodded slightly, and then ordered:


    "Since I can tell you this, it means that the demonstration stage is almost over, so you must act quickly... If it doesn''t work, you can also find other companies to cooperate in research and development."


    But Bodi opposite was a little worried:


    “GE has the most experience in this level of engines, and coupled with the unhappiness caused during the previous cooperation with Snecma, there is a high probability that it will not accept any joint research and development plans... and Pratt & Whitney is also in the development of V2500. The profits are huge, and I have long had the idea of ????going it alone..."


    "It depends on how you decide..."


    After all, Champine is not from Luoluo. For this reason, he has done his best to be kind and righteous:


    "In short, if you miss this time, you may not have the opportunity to re-enter this level of market in the next 20 years..."
