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 "little Zhuge" for Chang Haonan name.
Unfortunately not.
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, it would be very embarrassing if Party A asked someone about something outrageous and couldn't answer it...
But this piecemeal approach is really inconvenient. Understand what your competitors are doing.
Therefore, both Liang Shaoxiu and Kasolei are still doing things with the mentality of facing a powerful 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.
Coupled with Dassault’s proactive cooperation this time, it 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 using the conformal array solution.
If the construction period estimates of Air Police 200 and Air Police 2000 are followed, the entire process will last 6-8 months at the shortest.
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 low 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 Kingdom of David informed the UAE of its test schedule at the speed of light, Kasore found Liang Shaoxiu almost immediately:
"Liang, from the Kingdom of David The action is faster than we imagined."
He sat opposite with a solemn expression:
"Currently, the UAE has received news that IAI is preparing to launch the project between May and June this year. Conduct actual machine testing..."
In just a few years, Kasore's hair turned from black to gray.
Liang Shaoxiu subconsciously glanced at the desk 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?”
Testing in May-June indicates that the aircraft will be able to make its first flight in April at the latest.
And it is already 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 people are not good at fighting.
If left on the battlefield, this level of lying about military information would have been punishable by death...
And Kasore also looked embarrassed:
"The information we obtained before was that David Congress reserved the No. 01 machine for self-testing, and the slightly slower No. 02 machine was provided to the United Arab Emirates for testing. If the bid is successful, it can also be delivered as the first mass-produced machine... But now it seems that the Kingdom of David is Just take the No. 01 machine over..."
"Is it such a high priority?"
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 is 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 the Kingdom of David is obviously different.
It is 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.
Hearing Liang Shaoxiu's words, the expression on Casore's face turned playful:
"Maybe... 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 did not 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 blood 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..."< br>
With one sentence, the opponent Kasore's heart and lungs were suspended.
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 moment ...Have we not cooperated fully?”
“What else needs to be done?”
Liang Shaoxiu waved his hand:
“This time it is not only the design level, but also your factory needs to be involved.”
Casore was already a little confused:
“ But the plane has already been sent to you in 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.
Casore leaned over and took a look.
On it is printed 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 completed production.”
As he spoke, Liang Shaoxiu picked up a pen and drew circles on several beams on the picture:
“In the entire modification work, the ones that took the longest time are actually those composed of skins and long trusses. "
"Especially the piece that connects the back part of the fuselage to the radome, because of the complex geometric deformation and pre-connection force, it is impossible to rely solely on the shape and size of the part during the assembly process. Accuracy is required to ensure qualified components, so it is necessary to use a large number of frames with positioning and clamping functions during the wall panel assembly process 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:
"Yes...because the skin and trusses are large in size, weak in stiffness, and easy to deform under force, it is difficult to resemble them. The pre-connection process is used 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 long truss, as well as the accumulation during the positioning and clamping stages. The amount of deformation, so that all parts do not have to be transported to the assembly line for installation separately, but 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 modifications. Working hours..."
Kasore's breath was stagnant.
But on the surface, he still maintained his previous posture without moving.
Just glanced at Liang Shaoxiu.
"It sounds a bit radical..."
His eyes were full of suspicion:
"And... why didn't you use this technology at the beginning?"
Liang Shaoxiu turned slightly. Rolling his eyes:
“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 at the end of last year that it was truly usable in engineering.
As a result, he didn't notice for a while, and he actually said this sentence to himself, which was originally a complaint in his heart.
"I'm 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 in a pretentious manner:
"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..."
