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

On November 1997, 11, version 11 of TORCH Multiphysics software was officially released.

The reason why there is such a peculiar version number is because the first 0 represents the public beta version, the second 0 represents the Pro plus version, and 2 represents the second major version.

This is an update push only for XL Cup users.

So the version number for Dabei users is still 0.1.1.0.

But even so, this has become a watershed in the field of engineering numerical calculation.

The new gridding technology introduced by Torch Company in this update is combined with a dimensionality reduction algorithm for strongly nonlinear partial differential equations.

From the perspective of later generations, it was from this moment that numerical calculation, a tool whose original application scope was limited to a very few fields and was mostly used for reference and law analysis, was officially elevated to the level of "indispensable" .

It also marks the first shot of the Torch Group from obscurity to global fame.

At least, that's what it said in the "History of the Development of Data Computing" published decades later.

However, Chang Haonan himself, who occupies more than half of the book, sneered at this statement.

The owner said that although the software version 0.0.2.0 is very important to him and Torch Group, it is not as intuitive as what is written in the book.

After all, the Super Large Cup was only released to a very small number of users at the time, and 95% of users had no chance to experience it, or even knew that this model existed.

After all, a company or a product cannot exist without the general environment.

What really helps Torch Group go global is Huaxia Industry, which continues to develop and advance under its promotion.

……

As the unit most closely related to Chang Haonan, China Aviation Industry Corporation almost naturally became the first recipient of the new version update.

The luckiest among them is Factory 122 in Bingcheng.

Because along with the installation CD of the new software came Liu Hongbo, who had just been appointed as the manager of the numerical calculation business department by Chang Haonan for a few days.

Poor Professor Liu was just dragged into the trap by his junior brother with a generous salary, and the first thing he did was to go on a business trip.

And I have to fly back to school for two classes every week.

The textbook was actually written by the other party.

It makes absolutely no sense.

Of course, the complaints are just lip service. The five-digit monthly salary in the late 90s was still not good enough.

So the difference is still there.

"Professor Liu, I have admired you for a long time. It is truly an honor for you to come to our Ice City in person..."

The person who came to greet him was Cui Wenxue, the general manager of Bingcheng Aircraft Industry Group.

Although he got to the top by building cars, Bingfei is still a unit in the aviation industry system, and its core is still the helicopter business.

Bingcheng Automobile's achievements can consolidate his position within the Bingfei Group.

But if you want to go further in the aviation industry system, you still have to get the helicopter as a sign.

Therefore, although Cui Wenxu only knew a little about helicopters, he still showed enough respect for Liu Hongbo, who came to work on the project in person.

In fact, as far as the latter's identity is concerned, it can even be said to be a bit too enthusiastic...

"Hello, Mr. Cui, would you please come out and make a trip in person..."

As he spoke, a long breath came out in front of him, and his glasses were covered with a layer of frost.

In mid-November, the temperature in the Ice City was already below freezing.

How could Chang Haonan, a Northeasterner, think of reminding others to pay attention to the temperature?

So Liu Hongbo, who set out from the capital, was unprepared for this.

When I got off the plane, I went straight into the terminal and got on the bus, so I didn't feel much.

Now I got off the bus and stood at the gate of Factory 122 for a while, feeling numb from the cold.

But in order not to affect the image of Torch Group, we have to hold on...

Fortunately, Cui Wenxue saw that Professor Liu was not well equipped and could not adapt to the dry and cold weather in the Northeast. He took off the leather hat on his head and handed it to him, and then walked quickly into the factory together.

As he walked, he did not forget to introduce an old man who had been following him just now.

Although he looks ugly, he is energetic.

"This is Comrade Guo Jingshan, the person in charge of the Z-9 technology introduction project and the chief designer of the Z-9C, Z-9 armed version and civilian version H425."

"..."

"Are we going directly to the factory?"

Liu Hongbo looked at the increasingly larger buildings in front of him with some doubts.

Although it was his first time here, he could tell from the tall and unlayered style that this should be a production workshop.

"I'm really sorry, Professor Liu, the design work during this period was all completed in the design room here."

Guo Jingshan, who was walking next to him, replied:

"In the beginning, our 602 Institute was just a research laboratory supporting Factory 122. Later, although the scale became larger, we still retained the tradition of placing the design studio inside the factory..."

While talking, several people walked into the workshop one after another.

The glasses lenses that had just returned to transparency were suddenly covered with fog again.

Fortunately, the heating inside the workshop was sufficient, and Liu Hongbo quickly saw the whole inside.

Having already done many projects, it was naturally not his first time to enter a place like this, but compared to the other places he had frequented before, the production line at Factory 122 seemed a bit bleak.

If we only look at the aviation business, then Bingfei and Guifei are basically brothers in the same boat.

It's in a remote location, and there aren't any popular models.

In the huge workshop, there were only a few scattered helicopters of different versions and models.

On the contrary, further away on the production line, there seemed to be more of a small twin-engine propeller aircraft.

"Ashamedly, our 122 factory's operating conditions in the aviation business are average, so the number of orders is not too many, and most of the work stations are in a state of shutdown."

Regarding the current situation of Bingcheng Aircraft Group, Cui Wenxue is generous:

"Thanks to the help of Mr. Chang of your company, our small aircraft obtained airworthiness certification from the United States and the European Union without much effort, and then we signed a large order for 30 aircraft. Otherwise, in this workshop, Not a few people can be seen at a glance..."

Since the Y-12 is the only aircraft in China that has undergone FAA airworthiness certification before, Chang Haonan had previously involved many technicians from Ice City when he was researching anti-icing technology and negotiating with the European Union.

That's why Cui Wenxue knew the ins and outs.

After hearing this, Liu Hongbo finally understood why people were so enthusiastic about him.

Of course he knew what he was worth. He was quite famous in Jinghang University. After leaving school, who would know who Liu Hongbo was? He had done many projects in Haojing before. How could he have ever seen someone greet him personally by the general manager?

It was just for the sake of Chang Haonan and the Torch Group.

The previous doubt was that Bing Fei did not seem to have any direct relationship with his junior brother.

But now that I think about it, it makes sense.

Based on the various big news that Chang Haonan has made in the past year and a half, the entire aviation industry may have had some influence from him.

After a brief tour of the workshop, Liu Hongbo took the lead in returning to the topic:

"Mr. Cui, Mr. Guo, do you want to go take a look at the helicopter design that needs our assistance?"

The two people next to them looked at each other, and it was Cui Wenxue who spoke:

"Okay, then let Mr. Guo take you over to understand the situation. I don't have a deep understanding of aviation technology, so I won't go to the layman to guide the expert."

After a brief farewell, Cui Wenxue left the workshop with a few people.

Guo Jingshan noticed Liu Hongbo's curious expression, so he led the latter towards the design room and explained:

"Mr. Cui mainly manages the automotive business. Regarding specific issues related to aircraft design, he basically leaves me in charge."

Generally speaking, the heads of the groups under the Aviation Industry Corporation of China will have at least relevant educational background.

Bingfei Group and Cui Wenxue are in extremely special situations.

"I see."

Liu Hongbo nodded:

"That's not bad."

If a leader cannot understand what he is doing, it is better to at least know how to let go than to give blind orders.

"That's true. If we hadn't made money from selling cars, we wouldn't have been able to afford the money to ask you for help this time..."

Guo Jingshan replied with a smile.

While he was talking, he had already brought Liu Hongbo to a computer in the design room.

"This is our preliminary plan for the subsequent development of the Z-9 model. If nothing else happens, we may have long-term cooperation..."

The research and development strength of Bingfei Group is really weak.

Even though they have tried their best to expand in the past two years, Bingcheng has inherently limited development.

Moreover, it is really difficult for a technical team full of novices to succeed, and it cannot be led by Guo Jingshan alone.

Therefore, hiring foreign aid is a more sensible choice.

"Let me take a look."

Liu Hongbo put aside the hat Cui Wenxue had given him before, sat in front of the computer and started browsing.

What surprised him was that the entire document was full of details and very long.

To a certain extent, it can even be said to be a development plan for the helicopter industry!

"We want to develop four series based on the Z9?"

Liu Hongbo raised his head and looked at Guo Jingshan, who had been standing beside him.

"Yes."

The latter nodded immediately:

"Some time ago, we have solved some defects in the transmission structure of the Z-9 from the prototype, and found that this model has the potential to develop to about 6 tons."

"So, our current plan of Bingfei is to rely on the Z-9 prototype to develop four different configurations: assault transport type, special armed type, naval type and civilian type, and then build a complete 4 -6-ton helicopter model spectrum, becoming the vanguard in my country’s general aviation field!”
