Small·F—22。

Little F-22!

At present, the F-22 is the only advanced fighter of the next generation in the world that will be mass produced and put into service.

The model that Zhuang Jianye accidentally fell out of the bag is very similar to the F-22 made in the United States. It adopts the conventional layout. The nose adopts the diamond structure suitable for stealth. The trapezoidal wing and the horizontal tail in the rear are also processed in parallel according to the radar stealth.

Roughly speaking, the F-22 is the same as the F-22, but if you look closely, you will find that the model is essentially different from the F-22.

The first is the intake port. The traditional rectangular intake port is used in F-22, but the internal processing is carried out. The complex S-shaped structure is adopted to block the huge fan blade of the aeroengine with radar reflector, which not only realizes the stealth effect, but also makes the air intake of the engine more reasonable and efficient through complex calculation.

Zhuang Jianye's model is obviously surprised with F-22 in this respect. Instead of using the complicated internal S-shaped inlet of F-22 for stealth treatment, it uses a streamlined protuberance for shielding.

It's very funny for outsiders to see that the plane has two bulges on both sides, because from the front, the plane looks like a puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer puffer.

However, Mahmoud was shocked by this kind of streamlined protrusion, because of the similar inlet layout. He heard the introduction of American aviation experts at an academic seminar he attended last year. His scientific name is supersonic inlet without boundary layer, abbreviated as DSI in English.

Because it looks like a mussel, some people call it a mussel inlet.

The most important advantage of this device is that it can greatly reduce the total structure of the aircraft body on the premise of ensuring the stealth of the aircraft, so that the aircraft does not need to set up a complex S-shaped inlet structure in the body as the F-22 does, and only needs to set up a simple DSI at the inlet to solve the active problems such as stealth, air intake efficiency and heavy structure.

The second is the vertical tail. Although the vertical tail of the model, like the F-22, is V-shaped eversion, the vertical tail of the model is movable, which can be seen from the angle of the vertical tail deflection on one side when the model falls to the ground.

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

Finally, and most importantly, the fuselage of the model plane is more rounded than that of the F-22. This is due to the size of the internal magazine on the one hand, but on the other hand, it also shows that the model pays more attention to the aerodynamic layout and flight quality of the adult while giving consideration to stealth.

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

Generally speaking, the so-called integrated lift body takes the whole fuselage as a whole, which has very strong lift properties, not limited to traditional lift components such as wings.

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

The most typical example is that the traditional strake wing is integrated into the extension of the inlet. In this way, in the case of reducing the structural weight, the flight quality of the aircraft is not reduced, but the aircraft with traditional layout is stronger.

There are many similar details on the model. Mahmoud served in the air force in his early years. He was a well-known ace pilot in Algeria. Later, he studied in Moscow air force University of the Soviet Union and obtained a master's degree in aviation engineering. Later, he obtained a doctorate in aircraft design from Imperial Institute of technology in London.

It can be said that he is one of the few senior officials in the Arab world who knows both practice and theory. Otherwise, he would not be invited to attend the academic exchange meeting held by the top aviation experts in the United States. After all, the top academic meeting is really not understandable to ordinary people.

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

If not, he would not be able to see many extraordinary things in the model at a glance.

However, when he exclaimed in surprise and was ready to take a closer look at the extraordinary details in the model, Zhuang Jianye stuffed the model together with the scattered documents into his briefcase, then stood up and apologized to Mahmoud and others: "I'm really sorry, please forgive me."

Finish saying, carrying Baotou also don't return of turn to walk.

"Wait ~ ~"

seeing that Zhuang Jianye was ready to leave, Mahmoud finally couldn't sit still. The model at a glance was really attractive, especially the start-up layout of many frontier aviation fields applied in it was almost monopolized by the United States.

Although the Americans at the academic exchange, seemingly generous to share their latest research results with aviation scholars around the world.

But in the eyes of the vast majority of scholars, the sharing of American aviation experts is more ostentatious than practical.

Because American experts didn't mention any of the core things, such as specific parameters, production materials and experimental data, in the exchange report. The whole article is full of empty and boring boasting about what is subversive, what is advanced and what is leading.In fact, I just want to express a word. Don't bother about Barra's combat aircraft. It's useless for you to do it. We in the United States are a whole generation ahead. Whatever you do is out of date. What's the use of those thankless ones?

Yes ~ ~ our great America is not for one country, but for all the countries on the earth.

It's so arrogant, not to mention Russia and France, which are full of self-esteem. Even Algeria, represented by Mahmoud, is angry with the arrogance of the Americans.

But what else can we do in the face of American technological hegemony? Anyway, the sky is falling and there is a high roof. At least Russia is more urgent than Algeria.

Mahmoud's mind is much more balanced, but even so, he still hopes to have the technical strength of the Americans, at least in North Africa.

I thought I would never see all this in my life. I didn't expect that Zhuang Jianye's hopeless fall would bring out the hope of extinction.

DSI, full moving vertical tail, integrated lifting body structure.

Although it's only a model, it's not a simple model to be able to integrate these cutting-edge things of the world's aviation aerodynamic layout into an aircraft.

In this case, how can we let Zhuang Jianye leave? No matter how, we should make things clear.

So Mahmoud stood in front of Zhuang Jianye and others with a gentle smile and said, "Mr. Zhuang, I saw a model in your bag just now. I wonder if it's the ultimate form of jzb-119?"

As a result, Zhuang Jianye didn't mean to talk at all: "I'm sorry, your highness Mahmoud, I have no comment."
