Chapter 247: The Willows and Flowers Are Bright

Is a canard aerodynamic layout aircraft good?

As long as this question is a knowledgeable aviation enthusiast, he will not hesitate to give the answer: "Of course, this thing is really awesome, bunker." ”

Then the question arises again: why is there no full canard aerodynamic layout in fighters, and some aircraft are still in a regular layout?

Well, this is a question worth pondering, and the reason is naturally yes

"I know, the reason is that the birthplace of the aircraft, the most powerful, the most cooked, and the most oily in the world's aviation industry, the US imperialists, did not put the canard aerodynamic layout fighter into the finalization."

That's why, my big American imperialist didn't play with this kind of canard aerodynamic layout aircraft.

In the United States, where the aviation industry is the most developed, there is no fighter with a canard aerodynamic layout, which is indeed a bit puzzling, but there is also a reason why the United States has opened another mainstream technology tree.

That's right, isn't it just to create a detached vortex that can flow through the leading edge of the main wing? It's easy, and so will we. I have edge wings, which can also achieve the effect of a close-coupled canard aerodynamic layout.

In the sixties, aerodynamics discovered that the eddy currents of the leading edge of the wing with high energy could be increased to enhance maneuverability.

As a result, aerodynamic designers began to work on technologies that could generate leading edge detached vortices, which led to two major branches of technology: edge strip wings and close-coupled canard aerodynamic layouts.

That is to say, it is not only the close-coupled canard aerodynamic layout that can be matched with the side plates, but also the side strip wings that can produce the leading edge of the main wing and the vortex that are out of body seem to be possible, so that the side plate technology really does not need to be hung on the No. 10 project.

The research on the edge wing is also gradual. It has gone through three stages, from the early F16, F18, and SU27. With the first stage of the edge wing design, there are two types of triangles: the "S" shape and the triangle with an inward curve. This is an early study of the edge strip wing that is not too thorough. Come up with some of the more conservative schemes.

However, in the later Super Hornet and Thunder aircraft, there was a further Gothic large side strip wing, which was greatly improved compared with the first generation of F16 and SU27 used in the first generation of side strip wings, especially in the efficiency of vortex generation to a new height.

Even the efficiency of the Gothic side strip wing in generating vortices can be said to be the strongest stage of the edge strip wing, and it is not much weaker than the close-coupled canard aerodynamic layout.

Of course, in the F22, which generates vortex through the folding of the fuselage, it can also be regarded as a variant of the edge strip wing, but in terms of efficiency, because it has to take into account the stealth performance, it is naturally a little inferior to the Gothic side strip wing.

Thinking of this, Yang Hui was very excited, this is really a mountain and a water, and there is no way out. Another village. really responded to Liu Jun's words, and now the side plate technology can not be hung on the tree of the No. 10 project.

Isn't it just the big side strip wing, what's this, let's do it ourselves, you need to know that the seven demons in the later world have changed to the stage of the dragon, and they have used the good thing of the big side strip wings, and now we are just changing the demon to the seven of the dragons, and we can use it with a little bit.

However, the current J-74 and J-75 aircraft are arranged with large side strip wings, and the changes are still a bit too big. I'm afraid it can only be used in the next change.,It's a little sad to think about it.,It's a little sad to think about it.,It's a little sighing to think about.,It's a little sighing.。

Gothic big side strip wings, this thing, Yang Hui's graduation technical thesis in college is this. It's not easy to get it done, it's just this damn pneumatic exploration time, and it's a bit of a hassle to change this gothic big side strip wing. Behind the main wing, there is also an outer section that looks like a side strip and a tail brace, which is quite troublesome to change.

A new way out was found. Yang Hui cheered up again: "Okay, I have thought of a new direction. Since the basis of this side plate technology is the rectification of the supporting vortex flowing through the outer surface of the main wing. That's easy, we can use edge wings instead of canard wings, and we can also achieve this effect. ”

Yang Hui's idea is very good, and Liu Jun also understands what Yang Hui means, but the current Bian Tiao Yi seems to be good in China

"Secretary-General Yang, it seems that there is no aircraft in China that uses edge strip wings in development, right? We looked at this as if it was going to be the same as when we first tried to put this thing on Project Ten, there was no possibility. ”

actually poured cold water on Yang Hui at this time, how can he bear this, he must tell Liu Jun well, and describe to him the bright future of our Seventh Master Demon Reform.

Coughing twice, he sat upright and said: "What you said is a problem, and it is not a problem at the same time, we can't use the side strip wing now, but it doesn't mean that we won't need it in the future." ”

Yang Hui, who was kind and seductive, began to instill in Liu Jun his vision for a better future: "You see that we have changed the Jianqi to the present, the change is big enough, right?" But what I want to say is that this is not the end of our Seventh Master's future. Now our seventh master has determined to develop to low-altitude and low-speed performance, and continue to approach the third-generation aircraft. The changes will definitely continue in the future, and at that time the side strip wing will be useful, and it will naturally be able to show its talents. ”

After listening to Yang Hui's statement, Liu Jun's eyes also lit up, hey, isn't this what Secretary General Yang said, and our seventh master will definitely continue to improve in the future. When the time comes, the upper strip wing and the upper side panel technology, thinking about the improvement of performance, will definitely be able to raise our seventh master to a new height.

The excited Liu Jun wandered back and forth in the office, silently calculating the combination of the side strip wing and the side panel, and then installing the Seventh Master, and began to make changes on the basis of the current Super Annihilation Sect Seven in his mind, adding side strips and side plates.

Suddenly choked and stopped talking, and the whole person couldn't cry or laugh: "Mr. Secretary General Yang, let me ask a question in a low voice, does the Seventh Master who has improved like this have anything in common with the MiG-21 in the future?" I feel that even if people from the MiG Design Bureau come to the MiG Design Bureau, they may not be able to see the relationship between these two aircraft. ”

I was thinking about it here, isn't this just a magic change, a magic change, and a magic change, and we don't do much of this kind of thing? If we don't change the magic on the seventh master like this, how can our technical level improve.

"Rest assured, there is no problem with this level of improvement, regardless of whether he and the MiG-21 will inherit some aerodynamic shape, as long as we know that we have a good aircraft, and at the same time, there is not much risk in the development of this aircraft, and the technical route is feasible."

From later generations, Yang Hui is accustomed to the ability of the Republic to change Soviet-made weapons, and said that this is still a small thing, not to mention our seventh master, let's talk about our 59 tank (Soviet prototype T54), which of the children and grandchildren is not full of children and grandchildren.

There is also our Hongqi-1 missile (the prototype of the Soviet SAM-2), the developed Hongqi-2, 3, 4, 12 and other ground-to-air missiles, which are still active on the news screen of the republic until Yang Hui is reborn; Hongqi1 also improved the target missile, passed off as SR71, and used it as a training tool in China: the subsequent improved B610 ballistic missile was exported to the Iran-Iraq battlefield, and the B611 was even more outrageous, and the technology was exported to the seven Turkish countries, and it was also changed to the point that it didn't even know it.

Knowing that the possible improvements in the future will turn the Seventh Master into his mother, he doesn't know it, but for the improvement of the Seventh Master, Liu Jun is still quite in favor of it, and began to think about it carefully.

"By the way, it seems that the eddies generated by the edge strip wings like the F16 are not very good now, at most they can achieve the combination of a medium-range coupled canard layout and side panels, is this necessary?"

At this time, Yang Hui remembered that the Gothic big edge strip was still locked in McDonnell Douglas cabinet in 85, and of course Northrop Company cabinet may also have it.

But this is not a problem, Yang Hui just knows this thing, especially since Yang Hui has also studied it, there is no problem, and it will be over if he becomes a genius. (To be continued......)
