Chapter 1126 Pre-connection process


    If Yael Kentz''s idea could be foreseen by the Chinese side, then Liang Shaoxiu would have to laugh three times and then arrange a name like "Little Zhuge" for Chang Haonan.


    It''s a pity that we can''t.


    At the beginning of the 21st century, China has almost no sense of presence in the Middle East.


    Lao Wu''s activities are mainly in the Kurdish mountains and the South Caucasus, and he cannot reach the level of the GCC.


    Even the bidding work was done by Dassault personnel in order to avoid suspicion.


    The Aerospace Power Group and the Electronic Technology Group only sent a few engineers in the name of accompanying personnel to be responsible for the technical details.


    Otherwise, if Party A asks someone about something outrageous and cannot answer the question, it will be very embarrassing...


    However, this piecemeal approach is really inconvenient to understand the situation of competitors.


    Therefore, both Liang Shaoxiu and Kasolei are still working with the mentality of facing a formidable enemy.


    The good news is that as early as two years ago, Torch Group reached a strategic cooperation agreement with Dassault Software, allowing the new version of TORC Multiphysics to be compatible with front-end design software such as CATIA, thus eliminating a lot of problems such as mesh misalignment or model adjustment. kind of trouble.


    In addition, Dassault''s active cooperation this time provided complete design parameters for the fuselage, which saved a lot of effort in the early design process.


    However, even so, time is still not entirely on China''s side.


    Due to the special fixing method of the "Gaoming" radar, Haofei Group needs to modify the entire tail, more than 70% of the back and about 30% of the belly of the Falcon 8Z aircraft.


    This workload is not only much greater than the global eye of the Swedes using the balance beam solution, but is even comparable to the G550 Sea Eagle of the conformal array solution.


    If the construction period of Air Police 200 and Air Police 2000 is estimated, then the entire process will last 6-8 months at the earliest.


    Including flight tests and basic functional tests, I am afraid that it will not be possible to go to the United Arab Emirates for actual machine testing until the end of the year, or even early 2005.


    Although it has not exceeded the 18-month deadline given by Party A, if it is much slower than the other two competitors, it will inevitably be suspected of rushing the work with insufficient completion.


    The bigger trouble is that when the research and development of early warning aircraft has essentially ended, the longer you delay at the factory stage, the more information will be leaked—


    Considering that there are so many people in the workshop, this is a situation that is impossible to completely avoid.


    Both parties have a clear understanding of this point.


    Therefore, after the David Kingdom informed the UAE of its test schedule at the speed of light, Kasore found Liang Shaoxiu almost immediately:


    "Liang, David''s movements are faster than we imagined."


    He sat opposite him with a solemn expression:


    "Currently, the UAE has received news that IAI is preparing to conduct real-machine testing between May and June this year..."


    In just a few years, Kasore''s hair turned from black to gray.


    Liang Shaoxiu subconsciously glanced at the calendar on the corner of the table:


    "That means there are still four months..."


    After speaking, he frowned slightly:


    "But I remember...two months ago you said that the modification work on the G550 was expected to continue until this summer?"


    The test in May-June shows that the aircraft will be able to make its first flight in April at the latest.


    And now it''s early February.


    It is equivalent to entering the final stage of modification...


    What''s going on?


    Liang Shaoxiu complained in his heart that no wonder you French are not good at fighting.


    If left on the battlefield, this level of lying about military information would have been punishable by death...


    And Casore also looked embarrassed:


    "The information we have received before is that the David Congress will reserve the No. 01 machine for self-testing, and the slightly slower No. 02 machine will be provided to the United Arab Emirates for testing. If the bidding is successful, it can also be delivered as the first mass-produced machine... But Now it seems that the Kingdom of David took Unit 01 directly..."


    "Is it taken so seriously?"


    Liang Shaoxiu couldn''t help but be a little surprised.


    In fact, both Dassault and Ericsson sent the first prototype directly for testing.


    But that''s because both France and Sweden are in a very stable external environment and are not in a hurry to use these two early warning aircraft.


    But the situation in David''s kingdom was obviously different.


    It''s really urgent.


    You must know that modern early warning aircraft can not only command air combat, but also conduct large-scale battlefield surveillance, or organize air units to conduct ground attacks.


    This can squeeze out a plane, which can be said to be a high level of attention.


    After hearing Liang Shaoxiu''s words, the expression on Kasore''s face turned playful:


    "Perhaps... it''s because the other party also knows the role you play in this model?" After staying in China for the past two months, he has become well versed in the art of Gonghuo.


    Although the former''s expression showed no change, his slightly narrowed eyes still revealed his inner uneasiness—


    A cooperation of this level like the Falcon 8Z is simply impossible to hide from real industry insiders.


    Just as the Chinese side was like a chicken after learning that David Guo was participating in the bidding, the other side would naturally give a super-standard response in order not to be embarrassed.


    After a few seconds of silence, Liang Shaoxiu seemed to have made up his mind:


    "Mr. Casore, we can try to shorten the entire aircraft modification cycle to about 3 months..."


    One sentence directly caused the heart and lungs of Kasore on the opposite side to pause.


    He even forgot to blink for a moment and just stared at Liang Shaoxiu dumbfounded.


    "However, this requires your full cooperation..."


    Kasore nodded subconsciously, and then it took two seconds to react:


    "Wait a minute...aren''t we already fully cooperating?"


    "What else needs to be done?"


    Liang Shaoxiu waved his hand:


    "This time it''s not just the design level, but your factory needs to be involved."


    Casore was already a little confused:


    "But the planes have already been sent to China...our factory can''t do anything except provide spare parts?"


    This time, Liang Shaoxiu just smiled mysteriously and did not give a reply immediately.


    Instead, he did some operations on the computer in front of him.


    Soon, with a creaking sound, the printer next to me spit out several sheets of A4 paper.


    Kasore leaned over and took a look.


    Printed on it is the structural diagram of the middle part of the aircraft, which is also the most critical part of the entire modification.


    "In fact, the hardware of the radar system, including the radome, has basically been completed."


    As he spoke, Liang Shaoxiu picked up a pen and drew circles on several beams on the picture:


    "In the entire modification work, the longest time-consuming part is actually these sidings composed of skin and long trusses."


    “Especially the part that connects the back part of the fuselage and the radome. Due to the complex geometric deformation and pre-connection force, it is impossible to ensure qualified components only by the processing accuracy of the shape and size of the part itself during the assembly process. Therefore, in the wall panel During the assembly process, a large number of frames with positioning and clamping functions are required to ensure the precise geometry and assembly quality during the assembly of parts to components..."


    Casore is also an experienced veteran, so these details are naturally clear:


    "That''s right... Because the skin and girders are large in size, weak in stiffness, and easily deformed under stress, it is difficult to use pre-connection technology like other parts..."


    Seeing that the other party was already on the road, Liang Shaoxiu changed the subject:


    “But we have a new technology that can calculate in advance the initial gap between the skin and the girders, as well as the amount of deformation accumulated during the positioning and clamping stages, so that we don’t have to transport all the parts to the assembly line and install them separately, Instead, it can be pre-connected in advance after the production of large parts... If the craftsmanship level is high enough, it can save about 40% to 50% of the modification time..."


    Kasore''s breath hitched.


    But on the surface, he still maintained his previous posture without moving.


    He just glanced at Liang Shaoxiu.


    "Sounds a bit radical..."


    His eyes were full of suspicion:


    "And... why didn''t you use this technology in the first place?"


    Liang Shaoxiu rolled his eyes slightly:


    "Of course it''s because the technology is too new, so it needs to be tested on your side..."


    In fact, the basis of this process is the flexible and adjustable production line developed by Yao Mengna in the early years.


    But it was not until Chang Haonan solved the calculation problem of large-size plate and frame deformation late last year that it was truly usable in engineering.


    As a result, he didn''t notice for a moment, and actually said this sentence to himself, which was originally a complaint in his heart.


    "Sorry I didn''t hear clearly...what did you just say?"


    Fortunately, it was in Chinese, so Kasore didn''t understand it.


    Liang Shaoxiu quickly cleared his throat and pretended:


    "I said, because the new process requires very high levels of workers and equipment, your factory in France needs to be involved to ensure that it can run at full power..."
