 It has been 12 years since the first flight of China's J-20, and the maneuverability has not been fully upgraded.

January 11, 2011 was a very important day for our air force. Our first and only fifth-generation fighter, the J-20, successfully conducted its first test flight on this day. But it took us many years to send this fifth-generation aircraft to the army for service.

After completing the first flight, a number of prototypes have been developed in China, and further experimental research on its performance has been carried out on this basis.

At the beginning of 2016, the mass-produced J20 successfully conducted its first test flight, and at the end of the year, a J20 dual-aircraft formation was formed at the Zhuhai Air Show to demonstrate aircraft movements; and it joined the Chinese People's Liberation Army Air Force in 2017.

The birth of J-20 is undoubtedly a "milestone" for our country, which is worth remembering. When the J-20 soared into the sky, China's military research institutes and Chinese military enterprises are telling the world in a unique way that the Chinese are presenting to the world at an astonishing speed and in a jaw-dropping way. Show our strength.

This is undoubtedly a proud day for Chinese military enthusiasts, because China has become the third country in the world that can independently develop fifth-generation aircraft. T-50 has already shown its face internationally.

It has been 12 years since the first flight. In these 12 years, J20 can be said to be the witness of our air force along the way.

When this aircraft was first in service, because our country’s engine technology was not yet mature enough, the engines of the J20 were imported from Russia, and the number of engines in Russia was not large, so the supply was not much, so the J20 Production is not fast.

Moreover, when our country developed the J20, it was also designed according to our country's own domestically produced engine. Therefore, although the Russian engine can be used to equip the J20, it cannot show all the performance of the J20.

However, after the J20 was in service, all this changed. In the same year that the J20 was in service, a new J20 was born. This new J20 uses a domestically produced engine, but the model has not been made public. At that time, many people thought that this engine was the turbofan 10 engine.

It was not until 2021 that Chinese officials announced that the J-20's "heart disease" problem had been cured, and it had been replaced with a turbofan 10 known as the "Chinese heart", and mass production could begin, which meant that It means that it will become the only fifth-generation aircraft in the world that can perform supersonic cruise.

Today J20 is a decisive trump card for China. But the original design goal of the J20 was not actually achieved. With the passage of time, the way of fighting has changed, and J20 will continue to improve.

The most critical point of the J20 upgrade is the engine. The standard model of the J20 is the "Emei" turbofan-15, and all technical indicators are moving closer to the F119 engine of the F22. The dynamic vector nozzle is stronger than the F119, and at the same time, it will not become a "fuel rat" like the F119, and it will not have the problem of short legs of the F22.

In the early years, the J20 underwent a large-scale transformation. According to a media report, the J20 will have certain improvements in maneuverability and firepower.

The first is the power. Adding dual thrust vectoring nozzle engines to the J20 stealth fighter can make the tail of the fighter tilt once, thereby shortening the take-off and landing time, and also allowing the fighter to improve the maneuverability of the fighter when it loses control. sex.

How strong the mobility of the J20 is, we may not know until the equipment of the J20 is fully upgraded and put into use, but we can use a video for comparison, and everyone can open their minds.

In Marvel's "Iron Man" series of movies, we saw a very advanced technology, that is, there are five propellers on the metal armor, and each propeller is installed on the back, limbs and legs respectively, so Iron Man can control his body at will, is very flexible, and can make the metal armor move in different directions.

So whether the binary thrust vectoring nozzle engine equipped on the J20 will bring us the same steering effect, let us wait and see, of course this is just an illusion, we need to build on the basis of science and technology to perfect our The J20.

Second, in terms of firepower, we will comprehensively strengthen and upgrade the J20. In order to make the fighter better and improve its stealth performance to the extreme, the price paid is to sacrifice some of its original performance.

If the stealth fighter wants to achieve the effect of stealth, it must be equipped with materials that can not be detected by radar, and the model must be transformed into a unique appearance. It is used to distract the attention of the radar, which can reduce the visibility of the radar, so as to achieve the effect of stealth.

This is why the J20 we saw has such a strange shape, and its external accessories are also limited. In order to increase the attack power, someone once photographed that multiple combined external pylons were installed on the J20 to increase its ammunition load, which can increase the firepower.

In addition, another problem that J20 has to face is output. After all, the number of F-22s in the U.S. military has reached 186. Even if the F-22s are discontinued, according to the saying of "leisure to the enemy", it is not impossible to re-produce them. In addition, another F-35 of the United States is also in the "Crazy Raiders", and Lockheed Martin delivers 1,000 F-35s around the world at a rate of one every three days.

On the contrary, the J20 can only produce dozens of aircraft a year. In addition, countries such as Japan, South Korea, and Australia are also purchasing a large number of F-35s. Therefore, in the days to come, the number of fourth-generation aircraft of our opponents will decrease Bring us a lot of pressure.

In any case, J20 is a trump card of the Chinese Air Force. In the next ten years, it will be the main force of the Chinese Air Force's homeland air defense operations. A series of new air combat concepts and technologies will be tested on the J20 in the future. Respect Please look forward to it.
