Chapter 507: What We Learn Is How to Fish

Song Lao also sighed on the side, he knows, the domestic J H 7 uses computer-aided design, but when processing, it has to be converted into drawings, because of the lack of domestic processing equipment, this direct computer docking processing, which requires the cooperation of multi-axis linkage CNC machine tools, what about domestic? Most of them are manual.

To design and produce modern fighters, it is not a simple slogan, this requires the industrial progress of the entire country to do, and when this project comes out, the country's industry will also be greatly improved.

"What are you doing here?" Qin Feng came to the other side, and when he saw the graphics on the computer, it was even more strange, because what he saw was not one part, but a lot of parts, these parts were constantly docking on the screen, forming a complete part one by one, and finally there was a nose, the air intake under the nose, which was very conspicuous, almost the same as that of the F-16.

"This is a simulated assembly." During the visit, Lamor was almost always next to Qin Feng, and when Qin Feng asked a surprised question, the other party explained: "After we design it, we will first simulate it on the computer to see if there will be problems during assembly." If we have a problem that cannot be assembled, we can also analyze and solve the problem to improve our design. ”

A lot of designs are cheating, and the design alone is fine, but when combined together, it comes out, for example, a simple screw, the front is blocked by another device, and it can't be screwed in, what should I do at this time?

This can only be found when the real equipment is assembled, when designing, who will pay attention to these details, but now, with computer simulation, it is completely different, they not only design parts and components on the computer, but also carry out a piece of simulated assembly on the computer, through simulation to find out whether there is a problem, in this way, exposing the problem in advance, it is obviously a way to get twice the result with half the effort.

Qin Feng heard Lamour's words, and couldn't help but sigh, he didn't come out to see it once, he always sat in the well and watched the sky, now, he knows what the world's advanced level looks like, and he also knows how big the gap between his own side is.

In later generations, when it comes to the No. 10 project, there will always be some people who will be self-righteous and subjective, saying that the Jian-10 is a copy of Israel's Lion fighter, and that Israel's fighter technology was given to China in its entirety, so that China developed the Jian-10, which is clearly a kind of layman's slander.

The aerodynamic layout of the two is the way of increasing the delta wing of the canard wing and the air intake of the belly, but only the layout of the canard wing is different, the J-10 is a medium-range coupling, and Israel is a close-range coupling.

Israel's Lion fighter is the role of a bomb truck, replacing the A-4 attack aircraft, which is to throw bombs, while the domestically produced Jian-10 is mainly to seize air supremacy, and the mission is also different.

The technology of J-10, which comes from J-9, is a suitable layout that took more than 20 years to find in a wind tunnel, and it can only be said that it is the same end.

There are even people who say that the J-20 copied the MiG 1.44, then it is even more nonsense, the J-10 and the J-20 were successfully developed, and the Lion fighter and the MiG-1.44 were given up after several test flights, they are just similar in appearance, and they must not be said to be plagiarized relationships.

However, in the design of the J-10, it is indeed related to Israel, not to copy their fighters, and they will not allow their own side to copy, what they learn from Israel is not the specific design of their Lion fighter, but the advanced design methods of modern fighters!

If you want to design an advanced fighter jet, you must not follow the old way, you must keep pace with the times, from Israel, you have seen a lot of advanced design methods, such as computer design, analysis and simulation, etc. Come here and learn how to fish instead of the Israelis selling us a fish to eat!

There are many fighters in the canard layout, such as the EF-2000 "Typhoon", the Swedish JAS-39, and the French "Rafale", which shows that it does represent the trend of the world's fighter design.

Now, to visit here, everyone is deeply touched, even Song Lao, is also with a surprised look, he knows that it can be designed with a computer, but he definitely did not expect that it can also be simulated on the computer, there is no doubt that this is a very good way to reduce the problems in the assembly process.

When buying a computer for design, it will consume a part of the funds, but this is a great benefit for the development of the new J, it can make the later stage less detours, so, after going back, you must also carry out a drastic reform of the design method, and also use this kind of computer to design!

Song Lao made up his mind.

"So, since you can simulate the assembly, you don't need to make a wooden prototype, right?" Qin Feng suddenly raised a new question.

When developing a new fighter in China, it is necessary to manufacture a wooden prototype, which is learned from the Soviet designers, this kind of wooden prototype, you can intuitively see the appearance of the fighter, and the internal parts are also made in equal proportions, you can check in advance whether there will be problems with the assembly, and so on, this is the role of the wooden prototype.

Now, now that there is computer assembly, the wooden prototype can be omitted, right?

"Yes, we didn't need to make a wooden prototype, but we built one to be on the safe side." Hearing Qin Feng mention the wooden prototype, Saraf on the side spoke: "Now, let's take everyone to visit our wooden prototype and see the demeanor of our fighter under development." ”

The openness of the Israelites is surprising and somewhat moving.

Look at the country, when developing a new type of fighter, the secrecy is quite high, the Jian-8 is just a backward high-altitude and high-speed fighter, and now it is still a secret project, and the outside world rarely knows about it, and the Israelis, they are still developing a fighter, so they generously took it out and showed it to their own side.

They don't need to keep it secret, besides, just let people see, if they can imitate it, it is impossible, and on the plane, it is absolutely impossible, the automobile industry, that is, there is a certain Thai tape measure in later generations, can do this.
