Chapter 1126 Pre-Connection Process

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

Unfortunately, it can't be done.

At the beginning of the 21st century, China's presence in the Middle East is almost non-existent.

Old Wu's activities are mainly in the Kurdish Mountains and the South Caucasus, and he can't even touch the level of the Gulf Cooperation Council.

Even the bidding work was carried out by Dassault to avoid suspicion.

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

Otherwise, if the other party asks something out of the ordinary and can't answer it, it would be a big shame...

But this piecemeal approach is really not easy to understand the situation of competitors.

Therefore, whether it is Liang Shaoxiu or Casore, they are still doing things with a mentality of facing a big enemy.

The good news is that two years ago, Torch Group reached a strategic cooperation agreement with Dassault Software, allowing the new version of TORCH Multiphysics to be compatible with front-end design software such as CATIA, thus saving a lot of troubles such as mesh dislocation or model adjustment.

In addition, Dassault actively cooperated this time and provided complete design parameters for the fuselage, saving a lot of effort for the early design process.

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

Due to the special fixing method of the "Gaoming" radar, Gaofei Group needs to modify the entire tail wing, 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 also not much less than the G550 Sea Eagle using the conformal array solution.

If the construction period of KJ-200 and KJ-2000 is estimated, the whole process will last at least 6-8 months.

Including flight tests and basic function tests, it may take until the end of the year or even early 2005 to go to the UAE for actual machine testing.

Although it did not exceed the 18-month deadline given by Party A, if it was much slower than the other two competitors, it would inevitably be suspected of rushing the work.

The bigger problem is that when the development of the early warning aircraft has been essentially completed, the longer you delay in the factory stage, the more information will be leaked-

Considering the many people and eyes in the workshop, this is impossible to completely avoid.

Both parties have a clear understanding of this.

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

"Liang, David's actions are faster than we thought."

He sat opposite with a solemn expression:

"At present, the UAE has received news that IAI is preparing to conduct actual aircraft tests between May and June this year..."

In just a few years, Casore's hair has 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 saying that, he frowned slightly:

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

The test in May and June means that the aircraft can make its first flight in April at the latest.

And now it is early February.

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

What are you doing?

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

If it were on the battlefield, this level of false military intelligence would have been killed...

And Casore also looked embarrassed:

"The information we got before was that David would keep the No. 01 aircraft for its own testing, and the slower No. 02 aircraft would be provided to the UAE for testing. If the bid was successful, it could also be delivered as the first mass-produced aircraft...But now it seems that David has directly taken the No. 01 aircraft..."

"Is it so important?"

Liang Shaoxiu was also a little surprised.

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

But that was because both France and Sweden were in a very stable external environment and were not in a hurry to use one or two AWACS.

But the situation in David was obviously different.

It was really urgent.

You know, modern AWACS can not only command air combat, but also conduct large-scale battlefield surveillance, or organize air units to attack the ground.

This can squeeze out an aircraft, which can be said to be of great importance.

Hearing Liang Shaoxiu's words, the expression on Casore's face turned playful:

"Maybe... because the other party also knows the role you play in this model?"

After staying in China for two months, he has already mastered the way of adding fuel to the fire.

Although the former's expression did not change much, his slightly narrowed eyes still revealed his inner restlessness-

For real insiders, it is impossible to hide the level of cooperation like Falcon 8Z.

Just as the Chinese side was excited after learning that David was participating in the bidding, the other side would naturally give an extraordinary response in order to avoid embarrassment.

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.

"It 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..."
