歼 -20 is not as good as people?

20 1 1 year 65438+1October1day, a black painted plane with a sci-fi appearance slowly took off and flew in the air for 18 minutes, only 18 minutes. It is the fifth generation (Russian standard) stealth fighter J-20 developed by China. This test flight is a milestone in the history of China Air Force and even the entire aviation industry in China.

The J-20 also began to serve in the China Air Force on a small scale. The J-20 fighter plane not only makes China the second country equipped with stealth fighters after the United States, but also makes China's main fighter plane rank among the world's advanced levels for the first time.

For the J-20, there are both praise and disparagement. During the test flight of the J-20, there were endless doubts about the J-20 fighter.

The first is the engine of the J-20 fighter. Many people question whether China's J-20 fighter is equipped with Russian AL-3 1 engine, which not only has no vector thrust, but also has very small thrust, thus limiting its maneuverability and supersonic cruise capability. The Russian media even directly asserted that the J-20 is not a real fifth-generation fighter because it has no supersonic cruise capability and super maneuverability.

Secondly, the duck layout of the J-20. The outside world ridiculed the duck layout of the J-20 fighter, believing that this would affect the stealth performance of the J-20 fighter. For all kinds of doubts, the official did not come out to explain, but remained silent.

The "heart" problem of the J-20 fighter plane may have used Russian-made engines in the initial test flight, but with the breakthrough of China's excellent engines, this problem has been solved. CCTV also admitted that the J-20 has gradually replaced the domestic vector thrust engine WS- 15.

The argument that the duck layout of the J-20 fighter affects the stealth performance is also untrue, because anyone who is more careful will find that a Lombardy lens will be installed at the bottom of the J-20 fighter when it flies. If the stealth effect of the J-20 is not good, there is absolutely no need to install this device.

On the military parade, three J-20 fighters descended from the sky to participate in the military parade. Pilots who have driven the J-20 fighter have the following impression: the J-20 fighter has excellent maneuverability and good subsonic performance. If you enter the supersonic speed, it will be its world. The biggest feeling of driving the J-20 is that it is as quiet as a virgin and as moving as a rabbit. It can be seen that the pilot has a high evaluation of the J-20 fighter.

If someone still has doubts about the J-20, the technology possessed by the J-20 may convince him. During the test flight of the J-20, it was found from the J-20 fighter that the pilot's hand level in the cockpit was different from the traditional one. Traditional pilots put one hand in the middle, while the hands of J-20 fighter pilots are on both sides. As can be seen from this detail, the J-20 adopts a very advanced side stick drive system, while the traditional fighter adopts a central grip control system;

However, this system has great disadvantages, which not only affects the pilot's line of sight to the screen, but also affects the pilot's physical strength. The side stick drive system is to move the central handle to the right side of the fighter, so that the pilot can liberate his body. Generally speaking, he can fly semi-recumbent or semi-recumbent for air combat, which is very important to improve the combat effectiveness of pilots.
