Chapter 1003 DSI air intake

Previous page        Return to Catalog        Next page

    Small¡¤f-22.

    ? ?Little f-22!

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

    The model that Zhuang Jianye accidentally fell out of the bag is very similar to the American-made F-22. It adopts a conventional layout. The nose adopts a diamond-shaped structure suitable for stealth. The trapezoidal wings and rear horizontal tail are also designed based on radar stealth.  Parallel angle processing.

    At first glance, they are indistinguishable from the F-22, but if you take a closer look, you will find that the model is fundamentally different from the F-22.

    The first is the air inlet. The F-22 uses a traditional rectangular air inlet, but it is processed internally and adopts a complex S-shaped structure to block the aero-engine fan blades with huge radar reflective surfaces. This not only achieves the stealth effect, but also uses  Complex calculations make the engine's air intake more reasonable and efficient.

    Zhuang Jianye¡¯s model is obviously different from the F-22 in this aspect. It does not use the F-22¡¯s complex internal S-shaped air inlet for stealth processing, but uses a streamlined protrusion for shielding.

    To an outsider, the two bulges on both sides of the entire plane would be particularly funny, because from the front, the plane looks like an exploding pufferfish, with bulging cheeks and no murderous intent.

    But Mahmoud was shocked by this streamlined protrusion like a bulging cheek, because he had heard an American aviation expert introduce it to a similar air inlet layout at an academic seminar he attended last year. Its scientific name is Wushu.  Surface layer partition supersonic inlet, the English abbreviation dsi.

    Because it looks like a river clam, it is also called a clam inlet by some people.

    The main advantage of this device is that it can greatly reduce the total structure of the aircraft body while ensuring the stealth of the aircraft, so that the aircraft does not need to install a complex S-shaped inlet structure in the body like the F-22.  A simple DSI needs to be installed at the air inlet to solve the automatic problems such as stealth, air intake efficiency, and heavy structural parts.

    Next is the vertical tail. Although the vertical tail of the model is the same as the F-22, it is in a V-shaped eversion, but the vertical tail of the model is movable. This is from the angle of deflection of one side of the vertical tail when the model falls to the ground.  You can see it.

    This shows that this model is equipped with a more flexible full-motion vertical tail. Even without a high-performance vector engine, the aircraft still has strong air maneuverability.

    Finally, and most importantly, the fuselage of the model aircraft is more rounded compared to the flat body of the F-22. This is due to the size of the internal magazine on the one hand, but it also shows that the model has both stealth and stealth capabilities.  , paying more attention to the aerodynamic layout and flight quality of the adult body.

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

    ??In layman¡¯s terms, the so-called comprehensive lift body refers to the entire fuselage as a whole, which itself has extremely strong lift properties, and is not limited to traditional lift components such as wings.

    The advantage of this is that it can reduce the total structure to the maximum extent and improve the overall mobility.

    The most typical example is that the traditional slat wings are integrated into the outer extension of the air inlet. In this way, while reducing the structural weight, the flight quality of the aircraft is not reduced, but it is stronger than the traditional layout of the aircraft.

    There are many similar details on the model. As the saying goes, a layman can only see the excitement, and an expert can tell the truth. Mahmoud served in the Air Force in his early years and was a well-known ace pilot in Algeria. He later studied at the Moscow Air Force University in the Soviet Union and obtained a master's degree in aeronautical engineering.  , and later obtained a PhD 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 be invited to the academic exchange meeting held by top aviation experts in the United States. After all, such top academic conferences are really  It is not something that ordinary people can understand.

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

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

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

    After saying that, he turned around and left without looking back.

    "Wait~~~"

    Seeing Zhuang Jianye preparing to leave, Mahmoud finally couldn't sit still. He had no choice. The model he had glimpsed was so tempting, especially the many cutting-edge startup layouts in the aviation field used in it.  All beautified?? monopoly.

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

    But in the eyes of most scholars, the sharing by American aviation experts is more of a show than reality.

    Because American experts did not mention any of the core things such as specific parameters, production materials, and test data in their communication reports. The entire article was full of empty and boring bragging rights such as "subversion," "advanced," and "leading."

    After all, what I actually want to say is, don¡¯t bother trying to build any combat aircraft. It¡¯s useless for you to build it. We in the United States are already a whole generation ahead. Whatever you do is outdated, and it¡¯s still outdated.  What's the use of doing those thankless tasks?

    Yes~~We, the United States, are not targeting a specific country, but all countries on the entire planet.

    Such arrogance, let alone countries with huge self-esteem like Russia and France, even the Algeria represented by the humble Mahmoud was so angry when faced with the arrogance of the Americans.

    "It's so annoying, what else can you do in the face of the American technological hegemony but endure it?"  Anyway, if the sky falls, there will be a higher one to support it. At least Russia is much more urgent than Algeria.

    This thought made Mahmoud feel much more balanced, but even so, deep down, he still hoped to have the technical strength of the Americans, at least to be able to walk sideways in North Africa.

    I thought I would never see all this in my life, but I didn¡¯t expect that Zhuang Jianye¡¯s loss of consciousness caused him to lose hope again.

    dsi, fully moving vertical tail, integrated lifting body structure.

    Although it is just a model, it can integrate these cutting-edge things in the world's aerodynamic layout into an aircraft. Even if it is a model, it is by no means a simple model.

    In this case, how could it be possible to let Zhuang Jianye leave? No matter what, we must make things clear.

    So Mahmoud stopped in front of Zhuang Jianye and others with three steps at a time, 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 had no intention of continuing the conversation: "I'm sorry, His Highness Mahmoud, I have no comment."
