Hearing that this computer has not lagged behind for ten years, Yang Hui is noncommittal, he really wants to talk about this computer. Yang Hui can say without hesitation that this computer has lagged behind the international mainstream level.

But from the needs of the base, this computer really has to be able to do ten years without lagging behind, in the revolutionary graphics operation has not yet appeared, the old computer with the old DOS operating system can meet the needs of the base, basically there is no need to update.

It does not mean that computer technology cannot be used if it lags behind the advanced level, it is the best to meet the needs, and sometimes the advanced ones are not as good as those that can lag behind. Buying things is not only based on performance, but also on cost performance and your own needs.

Since this batch of computer-aided design systems can meet the needs, Yang Hui is too lazy to bother to debunk IBM's lies, so let him continue to brag.

The awesome IBM continued to brag, Yang Hui went to the side to see the installation of CATIA, the installation progress was constantly updated, with the prompt of the completion of the installation, Dassault staff continued to operate, and the installation had to be debugged.

After the commissioning, the Dassault staff stood up: "OK, Miss Yang, now you can try to operate it, you have been specially trained, I believe there is no problem in the operation." ”

Although the computer in the base is different from the computer model when he was training at Dassault, it probably hasn't changed, Yang Yue sat down, put her hands on the keyboard and kept typing the letter keys.

In the eighty-third year, the layout of the keys on the computer keyboard was not as reasonable as that of later generations, but in this case, Yang Yue was still proficient in typing various instructions.

With the dexterous beating of both hands, a series of instructions are entered into the computer to confirm the commands. A normal appears in the monitor according to the command.

Continue to enter the commands and the outlines are outlined one by one, then constrain the outlines until the sketch is edited, enter the 3D workbench, and enter a simple stretch command. Regular geometry parts are done.

Conventional geometries did not show the power of CATIA, and Chief Engineer Yu also saw this and asked to continue building a model with complex surfaces.

If you continue to model according to the data given in the data, the surface design will be more troublesome. This is especially true under the DOS system.

It took nearly a quarter of an hour to make a simple surface, and you can see the power of CATIA, complex surface design has always been a big problem for manual drawing, and computer 3D drawing is the most suitable to express the surface effect.

Continue into the component design environment and further process the surface shape. Finally, the effect of the parts can be seen intuitively. Yang Hui knew at a glance that this was the skin shape of the double delta wing junction of the new Jianjiao VII.

Looking at the constantly refreshing screen in disbelief, watching the excitement and not saying anything, these people who watched the excitement were thinking about one thing in their hearts: they must learn this powerful skill, and after learning this, the design of a new aircraft is not easy to grasp, simple and fast.

With the demonstration, there is an intuitive feeling of computer-aided design, which will be of great help to the follow-up promotion, at least now there are people whispering on the side to inquire when the training course of the base will start.

It was only at this time that Chief Engineer Yu paid attention to this auxiliary design software. Although the older generation can't keep up with the younger people, when they see the real effect, it's a different picture.

"Lao Bai, what you have introduced is a good thing, I used to hear 0132 boast about how strong this computer-aided design is, I still don't believe it, but now I have seen it thoroughly. It's really good, it's worth the money, and if it weren't for my age, I'd have to learn this thing. ”

After all, he is also an old man in his fifties, and Chief Master Yu sighed and didn't say more. Lonely and excited, he went to other offices. He is now going to inform the other office personnel to pack up the sensitive information. Prepare for Dassault to install this aided design system.

After the installation of a set of systems, everyone who watched the excitement had seen it, and they each went back to do their own thing, but the fifteen graduate students brought by Yang Hui from the imperial capital looked eager to try.

This computer-aided design is just so useful. Especially for researchers who do aerodynamic shape design, this is definitely a big weapon, in the shape design of the curved surface design is almost throughout, this is the same thing as cheating.

Some people are even wondering if there will be simulated wind tunnel testing software in the future, so that there will not be so much trouble.

Humanity prides itself on being able to think, and now it can think of doing computer-simulated wind tunnels. Will it be difficult to achieve it in the future?

The auxiliary design system of one has been installed, and nearly a dozen computers are distributed in various offices, which is absolutely pleasing to the eye, and the training course is also in full swing.

It is worth mentioning that the technical spy of Dassault Aircraft did not get the information he wanted in the end, and the secrecy work of the company was still very strict, at least it still prevented the careful thinking of the 'international friends'.

Yang Hui and Director Bai prepared to go back to the second institute together, no matter how much Yang Hui was needed in the first institute, Yang Hui was also a member of the second institute. It is still necessary to go back to the second institute to see, and Yang Hui still feels a little suspended after two years of taking out a qualified engine, so it is better to go and see the progress in person.

Leaving the house where birds don't, Yang Hui and Director Bai and Zhong Jianjian, who went to participate in the training, rushed back together, and when they came, there was only Chief Master Yu, and now that they are back, the little jeep is a little crowded.

In order to entertain these friendly Dassault staff members for the Republic and France, a long-distance truck was prepared, and under the surprised eyes of these foreign friends, Yang Hui took the lead in climbing into the back of the big car.

Don't take the truck as a car now, it's a guy who can travel on his behalf, at least Yang Hui thinks this truck is much more comfortable than riding a nephew.

Looking left and right, there was no other means of transportation, and these foreign friends seemed to understand. This time, you have to break the traffic rules to make a truck box, which is absolutely not allowed in developed France, but now

Seeing that some of these foreign people were still hesitating, Yang Hui could only helplessly explain: "Gentlemen, we don't have a passenger car here, and we have to walk dozens of kilometers to the next destination, so we can only take this pretty good truck." ”

This time, the Frenchman who obeyed the traffic rules had no choice but to deign for a while.

Looking at the tall truck compartment, the tall Westerners suddenly became a little at a loss, where should they get on the bus?

Yang Hui was already in the car, and when he saw a tall foreign person, he couldn't find a way to get in the car, and planned to go over to take a hand. But what I didn't expect was that this arrogant Frenchman, unwilling to accept the help of the Orientals, wanted to get into the car by himself.

So there is a funny scene, a Frenchman in trousers, a shirt and tie, and shiny leather shoes climbing into a truck, while a young Oriental who has been in good time sits in the car.

I took off my coat and handed it to my colleague next to me, because it would be difficult to get dirty. With his hands on the car, he raised his feet and stepped on the spare tire behind him, and his shiny leather shoes rubbed against the dusty tires, and others were distressed.

As soon as the other foot was raised, the whole person was suspended in the air, and the force on the foot was transmitted to the spare tire.

The spare tires are simply suspended by iron chains, and they will spin when they are subjected to external forces, which will cause problems.

As soon as the spare tire turned, he couldn't stand the force, and the French friend's center of gravity was unstable, and he fell down with a "bang".

Fortunately, the car was not high, and it was just a little embarrassing to fall down, so Yang Hui immediately jumped down to see if there was a problem with him.

"I protest, your reception is really not in place, you have to change my transportation, and definitely don't take such an unsafe vehicle."

What to do, it seems that the French will definitely not take the truck, how can this be.

Suddenly, Yang Hui remembered the nephew, this nephew was synonymous with backwardness in later generations, but its retro shape was very popular with Western friends in later generations, and now

"Well, if this gentleman else will change to a motorcycle, we have some motorcycles here, they are military motorcycles of Germany in World War II, and the quality is quite reliable." (To be continued.) )
