Small· F—22。

Little F-22!

The F-22 is currently the world's only next-generation advanced fighter that is about to be mass-produced and put into active service.

The model that Zhuang Jianye accidentally fell out of his bag is very similar to the American-made F-22, using a conventional layout, with a diamond-shaped structure suitable for stealth in the nose, and a trapezoidal wing and a horizontal tail in the rear are also treated at parallel angles according to radar stealth.

At first glance, it is indistinguishable from the F-22, but if you look closely, you will find that the model is fundamentally different from the F-22.

The first is the air intake, the F-22 uses the traditional rectangular air intake, but the internal processing, the use of complex S-shaped structure, blocking the radar reflecting surface of the huge aero engine fan blades, not only to achieve the stealth effect, but also through complex calculations, so that the engine air intake is more reasonable and efficient.

Zhuang Jianye's model is significantly different from the F-22 in this regard, and does not use the F-22's complex internal S-shaped air intake for stealth treatment, but uses a streamlined protrusion for covering.

This is particularly funny if it seems to outsiders that there are two bulges on both sides of the entire plane, because from the front, the plane looks like a fried pufferfish, with puffed cheeks, no matter how you look at it, there is no killing intent.

But Mahmoud was shocked by the sleek, bulging protrusions, because he had heard from American aviation experts at an academic seminar last year about the similar layout of the air intake, which is called the supersonic air inlet without a surface layer, or DSI.

Because it resembles a mussel, it is also called a mussel air intake by some people.

The main advantage of this device is to ensure that the aircraft stealth under the premise of greatly reducing the total structure of the fuselage, so that the aircraft does not need to be like the F-22, in the fuselage to set up a complex S-shaped inlet structure, only need to set a simple DSI in the air inlet to solve the stealth, air intake efficiency, structural weight and other active problems.

The second is the vertical tail, although the vertical tail of the model is the same as F-22, it is V-shaped valgus, but the vertical tail of the model can be moved, which can be seen from the angle of the model falling to the ground and the deflection of the vertical tail on one side.

This shows that the model is equipped with a more agile full-motion vertical tail, and the aircraft still has strong air mobility without a high-performance vector engine.

Finally, and most importantly, the fuselage of the model aircraft is more rounded than the F-22's flattening, which is due to the size of the internal magazine, but on the other hand, it also shows that the model pays more attention to the aerodynamic layout and flight quality of the adult body while taking into account stealth.

Because Mahmoud saw on it another epoch-making aerodynamic layout introduced by American aviation experts at the original academic exchange meeting - the integrated lift body structure.

In layman's terms, the so-called comprehensive lift body is to treat the entire fuselage as a whole, which itself has extremely strong lift attributes, not limited to traditional lift components such as wings.

The advantage of this is that the total volume of the structure can be minimized and the overall mobility can be improved.

The most typical example is that the traditional edge wing is integrated into the extension of the air intake, so that the flight quality of the aircraft is not reduced without reducing the weight of the structure, but is stronger than the aircraft with the traditional layout.

There are many similar details on the model, as the so-called layman looks at the lively, the insider looks at the doorway, Mahmoud served in the Air Force in his early years, is a well-known ace pilot in Algeria, and later studied at the Moscow Air Force University in the Soviet Union, and obtained a master's degree in aeronautical engineering, and then obtained a doctorate in aircraft design from Imperial College London, England.

He can be regarded as one of the few senior officials in the Arab world who understands both practice and theory, otherwise he would not have been invited to attend an academic exchange meeting convened by top aviation experts in the United States, after all, that kind of top-level academic conference is really not something that ordinary people can understand.

Mahmoud was not only invited to participate, but also benefited a lot from the exchange.

If it weren't for that, he wouldn't have been able to see the many extraordinaries in the model at a glance.

However, just as he exclaimed in surprise and was about to take a closer look at the extraordinary details in the model, Zhuang Jianye stuffed the model into his briefcase along with the documents scattered on the ground, and then got up and said apologetically to Mahmoud and the others: "I'm really sorry, please forgive me." ”

After speaking, he turned around and left without looking back.

"Wait~~~"

Seeing that Zhuang Jianye was ready to leave, Mahmoud finally couldn't sit still, there was no way, the model at a glance was too tempting, especially the start-up layout of many cutting-edge aviation fields applied in it, which was almost monopolized by the United States.

Although the Americans seem to be generous in sharing their latest research results with aviation scholars around the world at academic exchange meetings.

However, in the eyes of the vast majority of scholars, it is confirmed that the sharing of American aviation experts is more show-off than reality.

Because the specific parameters, the materials produced, and the data of the test are the core things, the American experts did not mention any of them in the exchange report, and the whole article was empty and boring ostentatious words such as what is subversive, what is advanced, and what is leading.

Speaking of which, in fact, I just want to express a sentence, don't bother to build any combat aircraft, it's useless for you to make it, our United States is already a whole generation ahead, whatever you do is outdated, what's the use of engaging in those thankless ones?

Yes~~ Our Great America is not aimed at a certain country, but to all the countries of the entire planet.

In such a arrogant way, not to mention countries like Russia and France, which are full of self-esteem, even Algeria, represented by the soft-spoken Mahmood, is so angry that it is angry in the face of the empty eyes of the Americans.

Anyway, the sky is falling and the top is high, at least Russia is much more urgent than Algeria.

This thought is much more balanced in Mahmood's heart, but even so, deep down, he still hopes to have the technical strength of the Americans, at least to be able to walk sideways in North Africa.

I thought that I would never see all this in my life, but I didn't expect Zhuang Jianye to fall so unwillingly, and he actually let the hope of extinction fall out again.

DSI, full-motion vertical tail, integrated lift body structure.

Even though it's just a model, it's not a simple model to be able to combine these cutting-edge things in the world's aerodynamic layout into one aircraft, even if it's a model.

Since this is the case, how can it be possible to let Zhuang Jianye leave, no matter how much he has to figure things out.

So Mahmoud stopped in front of Zhuang Jianye and the others in three steps and two steps, and said with a gentle smile: "Mr. Zhuang, I just saw a model in your bag, I wonder if it is the ultimate form of JZB-119?"

As a result, Zhuang Jianye didn't mean anything to talk about at all: "I'm sorry, His Royal Highness Mahmood, I have nothing to say." ”
