At the same time that Chang Haonan and Luo Hairong were discussing how to sell the plane faster.

Paris, France.

Professor Fernando Lorenzo, who was in the office of the National School of Road and Bridge, was poring over a scanned photograph that had just been sent to his mailbox on his computer screen.

The email came from Julian Cizeron, an old acquaintance of his at Airbus.

The other party is currently stationed in China to serve as the European representative at the Flight and Meteorological Safety Laboratory jointly invested by China and the EU.

The last time the two were in contact by phone, Cizeron complained that the cooperation agreement had only been signed for a few months, and that the lab was still a shelf with only a structure but no space, so they had nothing to do at the moment but were temporarily assigned to inspect the situation at a factory that once produced the nose parts of the Boeing 707 and MD82 aircraft.

His assessment at the time was that the factory was barely able to produce passenger planes from the 80s, but it was completely incapable of producing new models of Airbus aircraft, and wondered if he had chosen the wrong path to come to China.

As a former Dassault and current Airbus engineer, it's easy to leave Paris and Toulouse, but it's hard to go back.

However, in this email sent a few hours ago, Cizeron's attitude has taken a 180° turn.

Because today he saw a "very peculiar" fighter and happened to take a picture of it while it was in the air.

That's the one Lorenzo was looking at on the screen.

In the body of the email, Cizeron described his feelings in a shocking tone.

"I noticed that it did not retract the landing gear the whole time, so today should be the first flight of this aircraft, and as far as the first flight is concerned, it has already moved quite violently, not only climbing at an almost vertical angle at the beginning, but also performing several large grade turns and two rolls at high speeds, showing great maneuverability and agility......"

The large chunks of mixed uppercase and lowercase letters, as well as the continuous use of symbols and letters expressing amazement, made the email unfriendly to the reader, and if any student dared to write such an email, Lorenzo would have to call over and scold him.

In fact, even if it was sent by an old friend, he only read about a quarter of the way to the beginning and didn't want to continue.

But after clicking on the picture in the attachment, Lorenzo was stunned at first, and then patiently went back and read all the content behind:

"Although there were no references, my gut told me it should be bigger than the Mirage 2000, and, although I was reluctant to accept it, it should be on par with the agility that the Mirage 2000 does best, and it also uses a completely different aerodynamic design than all known models so far...... It may look a lot like some Swedish or Israeli fighter jets, but you should know that they just have a canard and delta wing design, but they are completely different in terms of aerodynamic coupling......"

"I watched the video of the air show at last year's air show, but at that time the plane didn't stand out much in terms of aerodynamic shape, mainly relying on abundant power, but this one is completely different......"

"It's hard to imagine that this is an aircraft designed by the Chinese, I mean, it's completely unimaginable compared to their manufacturing level, these Huaxia people either deliberately found an old factory to deceive and conceal their true level, or they have any special ability or skill in aircraft design......"

“……”

After reading the entire thought-provoking email, Lorenzo turned his attention to the photo again.

It's really clear, there's no sign of candid photography at all, and it's probably a telephoto lens.

The Huaxia people don't seem to be advertising this model with much fanfare, but apparently there is not much secrecy either, otherwise it is unlikely that a foreigner would shoot with such fanfare with a camera with a long lens.

Of course, due to the angle problem, it is still impossible to see the full picture of the aircraft based on this photo alone.

However, Cizeron's judgment is correct, the Huaxia people do have some special skills in aircraft design-

After the agreement was signed at the beginning of the year, JAA obtained the ice simulation and prediction software as agreed.

Despite being a limited version, the trial process at several airports helped them anticipate many of the risks that would lead to flight delays, saving airport operators and airlines millions of euros in costs over the course of several months.

Otherwise, there wouldn't be that flight and meteorological safety lab.

Moreover, the black technology that the other party can come up with seems to be far more than that......

Thinking of this, Lorenzo set his eyes on another email in his mailbox.

It was an official reply email from a company called Torch.

The content is that the National Road and Bridge School has passed the trial audit, and the installation documents will be shipped by air after the translation of the relevant user manuals and legal documents has been completed.

Although he himself has not personally experienced this software, from the preliminary explanatory documents sent by the other party, we can already get a glimpse of its advanced nature.

As a former core member of Dassault Systèmes' division, Lorenzo is highly sensitive in the field of numerical simulation.

He judged almost from the promotional materials that the developer of this software should also be an aircraft designer, not a programmer, because the other party has an extremely accurate grasp of the pain points faced in the actual engineering project, and the solutions described are completely logical.

In addition, TORCH Multiphysics is not even just a design simulation software, its calculation methods can be used in areas such as manufacturing and the development of new materials with a slight expansion of its calculation methods.

As for why it wasn't done......

Maybe it's because of a lack of manpower, or maybe it's because you haven't taken this into account yet......

Lorenzo obviously couldn't have imagined that this software would be able to compete in what seemed to be a top-of-the-line professional version (ver. professional), there is also a professional upgrade version (ver. professional plus）。

But even with the former, the features mentioned in it were enough to drive him crazy.

The promotional materials say that the comprehensive computational efficiency of numerical simulation can be increased by more than 5 times.

Lorenzo felt that even if this number was a little wet, it would be beyond the times to increase it by 3-4 times.

And since the Huaxia people were able to develop such anti-heaven software, it seems that it is not surprising to design a completely new fighter with relatively complex aerodynamic calculations.

……

Lorenzo's thoughts were interrupted by a sudden ringing of the phone.

was his student assistant.

"Professor, there are two gentlemen out there looking for you, saying that they have come from Italy, and they have not made an appointment, but you will definitely meet them."

"Uh...... Well, that's right. ”

Lorenzo rubbed his forehead and replied:

"Let them in, there's an old friend of mine."

A few minutes later, a tall, thin man with a blank face and the opposite of another - a stocky and kind-looking man walked through the door.

"Fernanio, long time no see!"

The former walked over as soon as he entered the door and gave Lorenzo a warm hug.

"Come on, Rory, who left me at the restaurant to pay last time?"

Lorenzo is unforgiving, but judging from his expression, the relationship with the other party should be really good.

"Let me introduce you, this is ......"

The man known as Rory stepped out of the way and wanted to introduce another person who was following him.

But before he could finish speaking, he was interrupted:

"No kidding, of course I know the former Peugeot team leader, France's national hero, but Mr. Jean Todd, who is about to be ruined."

As he spoke, he took two steps forward and shook hands with the other party.

In 1993, Jean Todd led the Peugeot team to the top three in that year's 24 Hours of Le Mans, and while it's hard to be a household name, it's hard not to know the name for a Frenchman who cares a little about racing.

However, the following year, because Peugeot rejected his offer to enter F1, Todd switched to Ferrari, a veteran F1 team that was already in decline at the time.

However, in the years that followed, the team barely improved, but still could only hover between third and second.

That's why there is a saying that he is about to be ruined.

"So, in order to save me from being ruined, Mr. Byrne brought me to you, Professor Lorenzo, and he said that you are one of the few people in the world who are best at computational fluid dynamics."

Todd, who was ridiculed, was not angry, but replied with the opportunity.

After all, it's not the first year that a similar headline has been written in the media.

"Come on, I'm not interested in your racing career, I just want to teach in school right now."

Lorenzo waved his hand, almost without thinking.

Actually, of course, he wasn't uninterested in racing, otherwise he wouldn't have recognized the unassuming Todd at first sight, but having already experienced a failed office fight at Dassault, he had already heard of the chaos within the Italian red team, so he wouldn't have entered the stadium because of some interest.

When you turn your hobby into a job, you often lose your interest.

Besides, for him, who has already worked in aircraft design, although there is speed and passion in the field of racing, there is really not much.

"Fernanio, Mr. Todd has already poached all the championship team of the Benetton team, can completely isolate the influence from the Fiat Group headquarters, and now there is only one person left to be responsible for the CFD calculation......"

Rory Byrne wanted to persuade his old friend again.

However, Lorenzo's attitude was resolute:

"I don't have that much energy to run around the world with you."

He waved his hand and sat back in his office chair, and out of the corner of his eye, he saw the emails on the screen.

This made Lorenzo hesitate for a moment, and then the conversation changed:

"But, Rory, I can give you a piece of advice."

"What?"

"You can try and learn this thing."

Lorenzo, with a solemn tone and a three-point joke, turned the monitor in the direction of Byrne next to him:

"If you believe my vision, then I dare say that this thing is at least five years ahead of its competitors in its class."

“TORCH Multiphysics…… Never seemed to have heard of it before? ”

"Yes, even though it's just a flyer, I looked at it and the content is pretty reliable."

“La Chine…… Or is it software developed by a Chinese company? ”

Byrne had a "you're not kidding me" expression.

"Yes, no kidding, I'm even thinking of bringing two PhDs over to talk to them."

Hearing Lorenzo say this, Byrne turned his head to look at Todd next to him.

The latter nodded.

"So...... Would you mind having one more person with you? ”
