Chapter 2673: Dondukov's gratitude

If there are only domestic technicians, then it doesn’t matter if you look at the Yingwen version directly, but if there are a few Xiong people, of course you must pay attention to the image. You must not let the other party see that they are from the Eagle country. This is the crystallization of Han Guo's technology.
Where does the technology come from? It can be from other research institutes.
When Dongdukov walked into the conference room, he was very grateful. He knew that he was just a bear countryman. Now they are holding a new fighter plan meeting. The level of this meeting is very high. , He was able to be invited over, in the past few years, the Han people really did not regard them as outsiders.
Looking at Xiong's country again, it's a mess. He has been in Han for the past few years and has become more and more fond of the atmosphere in Han.
"This time, I heard that it was President Qin who came here. I was quite dissatisfied with the wooden look." A companion next to him whispered to him in Xiong Guoyu.
Needless to say, President Qin is dissatisfied. Even in China, few people on the Jacques 141 can be satisfied. Look at the Su-27 and MiG-29. That is the aerodynamic layout of the advanced third-generation aircraft. The Mikoyan Design Bureau has begun to develop The layout of the fourth-generation aircraft, let’s take a look at the Yak 141. It’s like a copy of the MiG 25 and a slight modification of the rear fuselage. The performance of this aircraft will definitely not meet future needs.
There is no way. After all, since the jet era, the Yakerev Design Bureau began to fall behind and was quickly marginalized. They have never come up with advanced aircraft, and they have been reduced to only vertical take-off and landing fighters. The planes are not so good. Just look at their Yak 38. The navy is disgusted. If it hadn't played a role in the hands of the Han people, the Yaklev Design Bureau would really be useless.
This President Qin has a long-term vision, of course he doesn't like that kind of stuff.
"Well, don't talk, Qin is here." Dongdukov said: "This time, let's see what he is going to build. This opportunity is too rare for us."
Qin Guan walked in, looked at the people present, and nodded to them when he saw a few Xiong people, which made them feel flattered.
"Okay, let's have a meeting now." Qin Guan said: "I have seen the wooden model, even if it is a technical verification machine, we have to aim for the future, otherwise, what are we verifying? Everyone should know that the future What are the times like? This gentleman, Dongdukov, come and tell everyone."
Dongdukov was suddenly excited, Qin still remembered himself, and he was still here to speak!
"From the just-concluded date palm country war, we can see that the future war must be the world of stealth aircraft. With advanced stealth, it will be able to win decisive victory in future wars. There is no such aircraft. Yes, it will fall into the wind everywhere."
"Yes, the vertical take-off and landing we are doing here is just a way. If you want fighters to have advanced combat capabilities, you must have stealth. Therefore, I propose that our F31 fighters here The project is positioned as a medium-sized stealth vertical take-off and landing fighter."
The original design is impossible to have stealth capability. This is what Qin Guan is most dissatisfied with. Now, it is positioned as a stealth fighter, which means that all previous body designs have failed. , Must start over.
Qin Guan opened the speech, and on the screen of the projector, a figure of a fighter aircraft appeared. This is a three-view view from the front, from the side and from the top. When you see the aircraft at the first glance, Suddenly, everyone was surprised.
The first thing they noticed was the wing of this fighter plane, which was butterfly-shaped!
Today’s fighter planes must use swept wings. Different swept wings have different aerodynamic performance. Take the most popular nowadays, they are all sharp-pointed delta wings with a sweep angle of 40. The rear edge of the fuselage is vertical to the left and right, and the side strip wing is added to the front of the wing to form a smooth aerodynamic layout.
But now, it’s clearest from the top view. Its wing is not only the leading edge swept back, but the trailing edge is also swept forward, thus forming a special trapezoidal shape, which looks quite different.
Okay, now Han Guo has played all these things.
On the J-15, the variable swept wings are used, on the J-20, the duck layout plus the delta wing is used, and on the current J-31, the Eagle F is used. The aerodynamic layout of the -22, yes, this kind of wing is used by the Eagle F-22!
Moreover, the configuration of the entire fuselage is very similar to that of the F-22. The nose is diamond-shaped, and the air intake is just below the two sides of the nose, forming two parallelogram structures, which are perfectly integrated. Wings and tails are almost copied!
Now, the Eagles are also working hard to develop the F-22 fighter. This fighter is not as secret as the F117. After all, it is a fighter and requires a lot of equipment, so it was announced at the beginning.
As for the Han people, they are really the masters of plagiarism, and they copied the F-22 model.
Qin Guan copied it with confidence. After all, this kind of aircraft was originally an F-35, and F22 was both made by Lockheed Martin. When they designed it, they copied it. When they came to their own, they copied it. The eagle nation chose the big-mouthed monster X-32, and he must change one.
Although the model is very similar to the F-22, there are still many differences in details. For example, this aircraft looks thicker!
Of course, this is also helpless. Although it is said to have more parts consistency with the F-35A, after all, it needs to be stuffed with a lift fan in the front. If you want this aircraft to achieve the same range, you have to Make up for the lost space and find a place to store fuel.
If you put F-35A and F-35B together, you can find one slender and one plump, just like being a new-born woman and having a child. The latter is obviously blessed.
For a fighter aircraft, the range is also an important indicator. The Yak-38 can have a flight radius of 100 kilometers after a vertical take-off, which is definitely not enough. It is necessary to increase the fuel reserve, so it becomes such a Big fat man.
This led to an increase in flight resistance and a decrease in maximum speed. At the same time, the overload in maneuver combat was limited. However, as a vertical take-off and landing fighter, it was absolutely successful. Just look at the order for this aircraft. The models with vertical take-off and landing are the most.
