Chapter 1335 Flying Wing Layout

Previous page        Return to Catalog        Next page

    It¡¯s no wonder that everyone has such a sense of surprise. The main reason is that the angle of observation is different. When several leaders with aviation background saw the aircraft in front of the hangar, their profile was less than 30 degrees along the nose of the aircraft. This angle  It is indeed very similar to the J-8e.

    But after taking a closer look, I discovered that except for the nose and air inlet, which are similar to the J-8e, the middle and rear parts of the entire fuselage have nothing to do with the J-8e. To be more precise, they are not related to any other domestic and foreign models.  The aerodynamic layout of the aircraft is different, presenting an alternative, surreal, and subversive new layout without losing the modern flavor.

    It is like the legendary vampire bat spreading its wings, or like the reincarnation of the Aeolian pterosaur from the Jurassic period, giving people a wild and ferocious atmosphere in its agility.

    Yes, the layout of China¡¯s vertical take-off and landing fighter does not adopt the traditional conventional layout of the United States and Russia, but uses a full-lift layout that is close to a flying wing and a conventional one.

    Needless to say, the nose and the air inlet are based on the J-8e, or they are directly moved from the Zhenlong 2 verification machine, but from the air inlet onwards, they are similar to the J-8e or the Zhenlong 2 verification machine.  It doesn't matter half a dime.

    Two thicker side wings lead to two wide wings with great personality. Viewed from the front, the two pairs of wings are swept back at 40 degrees, like a typical tailless delta wing, but along the rear of the wings, you can find the wings.  It is not a typical delta wing, because the tail of the wing is also swept forward by 30 degrees, so that the two wings cooperate with the perfect wing-body fusion process to create an almost diamond-shaped semi-flying wing layout.

    Coupled with the two vertical tails extending from the engine tail nozzle that are inclined at 45 degrees and the two small ventral fins below, the entire vertical take-off and landing fighter looks very unusual.

    ¡° However, anyone with a little knowledge of aerodynamics knows very well that this seemingly alternative vertical take-off and landing demonstration aircraft has considerable endurance and maneuverability.

    The reason is very simple. This type of aircraft with aerodynamic layout is not without precedent. Not only has it appeared, but its overall performance is excellent. That is the YF-23 fighter jet jointly developed by McDonnell Douglas and Northrop in the United States.

    Its target competitor is the now-famous F-22.

    Although the YF-23 fighter jet lost to the F-22 in the final competition, it was not lost in technology, but in a concept that was too advanced, so that the slightly conservative US Air Force felt that the YF-23  The maturity of the fighter jet is not as good as that of the F-22, so the more traditional F-22 was chosen.

    In fact, the YF-23 fighter jet is superior to the F-22 in key indicators such as range, supersonic cruise, and stealth. In particular, its unique diamond-shaped lifting body aerodynamic layout almost combines the maneuverability that McDonnell Douglas is good at with North  The flying-wing layout that Ropp was proud of absorbed all the advantages. It not only had a huge bomb load, but also completely crushed any combat aircraft at that time in terms of combat radius and air combat maneuverability.

    It is precisely because of this that the YF-23 fighter jet has become the true pinnacle of the American aviation industry.

    Because the YF-23 fighter jet is so excellent, there has been a saying in the industry that the YF-23 fighter jet did not really fail, but was purchased in large quantities by the U.S. Air Force in the name of high-speed reconnaissance aircraft and equipped for the Air Force's Strategic Reconnaissance Wing.  , to become a new generation of peepers.

    Regardless of whether the rumors are true or false, one thing is certain, that is, the excellent performance of the YF-23 fighter jet is unquestionable. Because of this, when a group of chiefs and leaders with a strong foundation in aviation theory saw this vertical take-off aircraft in front of them,  After landing the verification aircraft, they would exclaim: "Is this the aircraft we designed?"

    There is no way, in fact, this kind of aerodynamic layout cannot be achieved by copying a cat, but requires quite powerful skills in flying wing layout, traditional trapezoidal wing, tailless delta wing, full-lift body, wing-body fusion, etc.  Experience and basic skills are enough to get started.

    After that, you have to have profound knowledge of flaps and ailerons, and have extraordinary accumulation in the fields of composite materials, metal materials, alloy materials, ceramic materials, etc., plus a R&D team that implements innovation throughout to be able to control such an avant-garde  The aerodynamic layout, otherwise you can just stare and do nothing.

    The reason is very simple. This kind of aerodynamic layout has many advantages, but it also has many disadvantages. The most important thing is how to ensure the maneuverability. After all, it is a fighter jet. It does not have super maneuverability. It is a living target in the sky, but it is similar to flying.  The wing layout inherently suffers from maneuverability.

    Coupled with the lack of assistance from horizontal tails or canards, the maneuverability of this type of aircraft under normal circumstances can make listeners sad and listen to tears.

    So how does the YF-23 fighter jet solve this problem?

    It is very simple to directly use the combination of ailerons and flaps to complete super maneuvers. In other words, the ailerons and flaps of the YF-23 fighter jet are very different from those on traditional aircraft., has been given a more important role. This foundation comes from another pinnacle of Northrop, the combination of flaps and ailerons on the B-2 stealth bomber.

    It¡¯s just that Northrop has sublimated this technology again on the YF-23 fighter. With the rear vertical tail and lifting body, the YF-23 fighter has maneuverability comparable to the F-22.

    The problem is that this flaperon combination maneuver seems simple, but not everyone can do it.

    Just like the B-2 strategic bomber, the Americans have long announced the basic principles and supporting plans. As a result, who else in the entire solar system besides the Americans has built a flying-wing stealth bomber?

    It¡¯s not that I don¡¯t want to do it, but I can¡¯t do it at all. If nothing else, the timing and control position of the flaperon differential combination of the B-2 is a headache. After all, it is a flying-wing aircraft.  It is recognized around the world that it is difficult to control. If you want to make this kind of aircraft obedient, it cannot be solved by using the flaperon differential. There are so many things involved.

    Northrop began to work hard on the flying-wing aerodynamic layout after World War II. It invested huge amounts of money, crashed several prototypes, and sacrificed more than a dozen pilots to accumulate huge experience.  Got b-2 and yf-23.

    Because of this, only outsiders think that the progress of the aviation industry is an explosive leap forward. In fact, before the leap forward, I don¡¯t know how many people have fallen behind in the accumulation of technology for decades.

    The army chiefs and leaders present are naturally not outsiders. They know very well that without strong technical accumulation, if they want to create an aircraft with the same aerodynamic layout as the YF-23 fighter jet, they are just trying to imitate others.

    But over the years, no one has heard that China Ascendas has dabbled in flying-wing aerodynamic layout. So where did the vertical take-off and landing demonstration aircraft in front of us come from?

    At this moment, the head of the headquarters, who had been silent for a long time, suddenly thought of something and turned to look at Zhuang Jianye: "Are your ty-22 drones still flying?"
