The military-industrial scientific research system of the academic master.

Chang Haonan's words are really too short.

So much so that before Liang Shaoxiu put the receiver to his ear, he had already finished half of his speech.

He didn't hear clearly in the first place, and his mind didn't react quickly enough, causing him to stand there in a daze for a while.

After a long silence, he asked in confusion:

"This...is it over?"

The so-called N-2-1 and N-1-2 refer to the fact that during the pre-connection process, the skin unit needs to be assisted in positioning by discrete positioning points at three positions before being clamped.

The first number represents the inner surface of the panel (the number of different skins varies greatly, so it is N), the second number is the arc direction of the panel, and the third number represents the heading of the panel.

After the skin unit is positioned, the long stringer can use one end of the skin heading positioning point as a reference and constrain the remaining degrees of freedom through the clamp.

But for the entire processing process, this is really a very insignificant detail.

This is basically the default mitigation.

It is generally believed that the specific method of three-point discrete positioning will only affect the operation process and will not affect the specific positioning effect.

Therefore, it is not even part of the industrial standard, but is determined by each manufacturer based on their own habits.

The relevant content was not mentioned in the hastily translated production document.

But Chang Haonan figured it out almost... in just a few seconds?

"In traditional processes, the arrangement of positioning points does not affect the assembly process."

As Chang Haonan answered, he looked at the follow-up content of the statement on the screen:

“But because we reserve both the deformation allowance and the gap release allowance during the processing, and there is basically no gap flow between the arc units of the wall panel, we need to allocate higher priority positioning points in the heading…”

"When I designed it, I set it to N-1-2 according to our custom. If the French use N-2-1, it will cause errors in heading positioning."

Liang Shaoxiu was also staring at the picture in front of him at this time.

But even if he tried his best, he still couldn't develop the same brain circuit as Chang Haonan:

"No...is there no other possibility?"

Although the latter analysis is very reasonable, it is well known that induction and deduction are not interchangeable.

More importantly, this made Liang Shaoxiu feel a little stupid.

However, when I thought that the other party was the founder of this set of technology, and I was just more proficient in its application, it didn't seem so unbalanced...

“I can’t say there isn’t any.”

Chang Haonan smiled and replied:

"But if it's something else, whether it's a calculation error or a production problem, the problem should be in both the heading and the arc."

"But if you look at the photos they sent, there is a neat gap in the heading direction, as if it was cut by laser, but the arc direction is very complete and fits perfectly... So it is most likely the reason I mentioned."

Liang Shaoxiu was speechless.

After adjusting the layout of the positioning points, the bandage clamping direction must be changed accordingly, so there is no need to ask again.

"All right……"

He took out a pen and quickly wrote down what Chang Haonan had just analyzed on the side of the report.

Fortunately, A4 paper is large enough, so there is no situation like Fermat where he could not write everything down.

After hanging up the phone, Marin, who had been sitting opposite, finally couldn't hold back his curiosity and came over quickly:

"Boss Liang, does this mean...it's been resolved?"

He could only hear Liang Shaoxiu's voice just now, but the latter was shocked by Chang Haonan right at the beginning and couldn't even utter a few complete sentences.

I can't really tell the final result.

"yes……"

Liang Shaoxiu flicked the report in his hand:

"It's Academician Chang after all... He just took a look and made a preliminary assessment of the problem, and also provided a solution."

Although he felt that Chang Haonan's method was a sure win, it was still not appropriate to open a glass of champagne for the other party at halftime in front of outsiders.

So there is still some room left.

As he spoke, Liang Shaoxiu pulled out a piece of manuscript paper, scribbled two lines on it, and then handed it to Ma Lin:

"Go quickly and send this information to Dassault!"

……

Meanwhile, in Toulouse.

After Casore said he was going to give feedback to the design team, all the engineers on site put down their work for the time being, packed up their things and prepared to go off work.

In fact, even Casore himself, who had just sent the message, was ready to take this opportunity to relax and adjust his tense emotions over the past few days.

"Charles, I remember you said a few days ago that there's a nice restaurant nearby?"

After returning to the office, he put on his coat and asked Bane behind him.

"Yeah... we have time today, we can go there together..."

There was actually still about half an hour before the end of get off work, but he had been working overtime for the past few days and was currently in a state where he was unable to carry out his work, so he didn't mind leaving early.

However, just when the two were about to run away, the liaison officer who was responsible for sending the message came hurriedly to the door.

"Supervisor, Manager, we just received a reply from Huaxia."

Cassore was stunned at first, then he noticed that the other party was holding only a piece of paper, and he understood:

Just one page.

And it was only less than an hour later.

Obviously a polite response.

For example, the situation has been noted and a reply will be given within x working days.

"Just put it on my desk."

He motioned to the contact.

At the same time, his hands did not stop moving, and he had already started putting on the scarf.

The latter was just an ordinary worker and did not think much about it. He placed the document on his desk as required.

Almost subconsciously, Cassole glanced over there out of the corner of his eye before putting on his hat.

then……

"Ok?"

His hand holding the hat stopped in mid-air.

There was indeed only a very short sentence written on that piece of paper.

But it was not the routine response he expected.

But with content...

[Please change the positioning method from N-2-1 to N-1-2, and change the bandage clamping direction to longitudinal at the same time]

Cassole shuddered violently.

"what happened?"

Not far away, Bane was ready, waiting to set off with Cassore.

But the latter did not answer immediately.

Just hung the hat back up.

Then came scarves, windbreakers…

"Quick, gather the engineers."

After returning to his work attire, Casore picked up the paper and walked out in a hurry while giving instructions:

“The solution has been sent.”

Bain:

"???"

……

It's not just Bane.

When a dozen on-site engineers heard Casore read out the contents on the paper, their first reaction was -

Are you just having fun?

After looking at each other in bewilderment, the engineer from before stood up as a representative:

"That's all?"

In fact, Cassore was a little unsure, but he knew that at this moment, he must not show any hesitation:

"Correct."

“This is the least-changing of the several possible solutions… We don’t even have to re-produce any parts, just adjust the positioning points on the pre-connected jigs and each skin unit, so it’s worth trying first.”

The following content was naturally made up by him on the spur of the moment.

But at first glance, it does sound like that.

Although the technical staff felt that this was a bit unreasonable, it was just as Casore said, the adjustment range of this plan was very small, and even if it failed, it would only be a waste of a few hours.

In fact, because the pre-connection process itself can be automated, there is even less actual work involved.

As a result, the entire workshop soon became busy again.

The engineers are already familiar with this set of operations.

Just twenty minutes later, the skin laying machine restarted and began to move on the pre-connected frame with a creaking sound...

"Do you really think this is feasible?"

After an unknown amount of time of silence, Bane came over and asked Casore in a low voice.

He had just seen what was written on the paper and knew that there was no long paragraph at the end.

"I'm... not sure."

The latter sighed softly.

Both of them are middle and senior management, so there is no need to hide too much.

"If such a huge gap can be closed just by adjusting the positioning method, then I can only say..."

Casore's expression was quite complicated.

From a project perspective alone, he certainly hopes that this will be successful.

But from a worldview perspective, it seems reasonable to fail...

"say what?"

Bain next to him asked questions.

"If this were possible, engineering would no longer exist..."

"hiss--"

Before Casore could finish his words, there was a collective gasp from the crowd slightly ahead.

The two looked in the direction of the sound and found that there was a commotion around the pre-connected frame.

Perhaps he noticed the gaze from the leader behind him.

A dozen people spontaneously split into two groups to give them a view.

In an instant, Kasolei's eyes widened slightly——

According to the assembly order, the first row of skin units in the heading direction have been assembled in place at this time.

But the three-centimeter-wide crack just now has disappeared at this moment.

The entire wall panel attached to the long beam fits perfectly!

Looking at the scene in front of me.

Cassore's lips moved slightly, but no sound seemed to come out.

Only Bane, who was closest to him, vaguely heard a few syllables:

"Engineering... doesn't really exist anymore..."
