It's no wonder that people have such a surprised feeling. The main reason is that the angle of observation is different. When several leaders of aviation origin saw the plane in front of the hangar, they had a profile less than 30 degrees along the nose. This angle is really similar to the j-8e.
However, after a closer look, we found that except that the nose and air intakes are similar to those of the j-8e, the middle and rear parts of the fuselage have nothing to do with the j-8e. To be more precise, it is different from the aerodynamic layout of any other aircraft at home and abroad. It presents a new layout that is alternative, surreal, subversive of tradition, but with modern flavor.
It's like the blood sucking bat spreading its wings in the legend, and the reincarnation of the wind god pterosaur in the Jurassic period, which gives people a kind of savage and ferocious atmosphere.
Yes, the layout of China's VTOL fighter does not adopt the conventional layout of the United States and Russia, but uses a full lift configuration close to that between the flying wing and the conventional.
It is needless to say that the nose and air inlet were moved directly from the j-8e, or the Zhenlong II, but after the air inlet, it has nothing to do with the j-8e or Zhenlong II.
From the front, the two wings sweep back 40 degrees, which looks like a typical tailless delta wing. But along the wing, it is found that the wing is not a typical delta wing, because the tail of the wing also sweeps forward 30 degrees, so that the two wings cooperate perfectly with the wing body fusion process, So that the whole presents a semi flying wing layout close to diamond.
In addition to the two 45 degree inclined vertical tails and two small ventral fins extending from the engine tail nozzle, the whole VTOL fighter is very different.
However, as long as a little knowledge of aerodynamics, it is very clear that this seemingly alternative VTOL demonstrator has quite strong endurance and mobility.
The reason is very simple. This kind of aircraft with aerodynamic configuration is not unprecedented. It has not only appeared, but also has excellent overall performance. That is the yf-23 fighter jointly developed by McDonnell Douglas and Northrop.
Its competitor is now the famous F-22.
Although the yf-23 fighter lost to the F-22 in the final competition, it didn't lose to the technology, but lost to the too advanced concept, so that the slightly conservative US Air Force felt that the maturity of the yf-23 fighter was not as good as that of the F-22, so it chose the more traditional F-22.
In fact, yf-23 is superior to F-22 in terms of range, supersonic cruise, stealth and other key indicators. In particular, its unique rhombic lift body aerodynamic layout almost absorbs the maneuverability of McDonnell Douglas and the advantages of Northrop's proud flying wing layout. It not only has a huge missile load, but also has a large number of missiles, Moreover, in terms of operational radius and air combat maneuver, it completely crushed any combat aircraft at that time.
Because of this, yf-23 fighter has become the real peak of American aviation industry.
Because the yf-23 fighter is too excellent, there is a saying in the industry that the yf-23 fighter did not really fail, but was purchased by the U.S. Air Force in the name of high-speed reconnaissance aircraft and equipped to the air force's strategic reconnaissance wing, becoming a new generation of stealers.
No matter whether the rumors are true or false, one thing is certain, that is, the excellent performance of yf-23 fighter is beyond doubt. Because of this, when a group of leaders with strong aviation theoretical foundation saw the VTOL verification aircraft in front of them, they would say: "this is our designed aircraft?" I'm very surprised.
There's no way. This kind of aerodynamic layout can't be made by imitating a cat or a tiger. It needs to have quite strong experience and foundation in flying wing layout, traditional trapezoidal wing, tailless delta wing, full lift body, wing body fusion, etc. to be able to enter.
After that, we 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. in addition, the R & D team that will carry out innovation all the time can control such avant-garde pneumatic layout, otherwise we can only do nothing.
The reason is very simple. This kind of aerodynamic layout has many advantages, but also many disadvantages. The most important thing is how to ensure the mobility. After all, it is a fighter, and it does not have super mobility. In the sky, it is a living target. However, the similar flying wing layout naturally suffers from the loss of mobility.
In addition to the lack of horizontal tail or canard wing assistance, the mobility of such aircraft under normal circumstances can make people sad and cry.
How did yf-23 solve this problem?
In other words, the flaps and ailerons of yf-23 fighter are very different from those of traditional aircraft and are given more important roles. This foundation comes from another peak work of Northrop, the combination of flaps and ailerons of B-2 stealth bomber.
However, Northrop upgraded this set of technology again in the yf-23 fighter. With the rear vertical tail and lift body fuselage, the yf-23 fighter has the mobility comparable to that of the F-22.
The problem is that this flap aileron combination maneuver seems simple, but not everyone can do it.
Just like the B-2 strategic bomber, the Americans have already announced the basic principles and supporting plans. As a result, who else in the entire solar system besides the Americans has built flying wing stealth bombers?
It's not that I don't want to do it, but that I can't do it at all. Let alone other things, it's a headache to grasp the timing of flap aileron differential combination of B-2 and how to control its position. After all, it's universally acknowledged that flying wing aircraft is difficult to control. If we want to make this kind of aircraft obedient, flap aileron differential combination can't be smoothed, and the things involved are just vast.
Northrop began to work hard on the aerodynamic configuration of flying wings after World War II. He invested a lot of money, crashed several prototypes, and sacrificed the huge experience accumulated by more than ten pilots, which led to the B-2 and yf-23.
Because of this, the progress of the aviation industry only outsiders think is an explosive leap forward. In fact, before which leap forward, I don't know how many people have fallen into decades of technology accumulation.
Naturally, the army leaders and leaders present are not outsiders. They know very well that they do not have a strong technical accumulation. To make a plane with the same aerodynamic layout as the yf-23 fighter is to imitate.
But over the years, no one has heard that China's take-off has dabbled in the aerodynamic configuration of the flying wing. How did the VTOL verification aircraft come from?
At this time, the head of the headquarters, who had been silent for a long time, suddenly thought of something and turned to look at Zhuang Jianye: "is your ty-22 UAV still going on?"
