The Chinese Air Force Star Equipment J-20 stealth fighter has become a hot spot for the majority of military fans in the past two days. The reason is that it is equipped with two domestic turbofan-15 engines and successfully flew for the first time.Some military observers believe that the J-20 has finally completely overcome the "heart disease" and has become a new "killer" that can truly be able to compete with the US military's F-22 and F-35 stealth fighters.

A video of a "climbing party" (referring to the military fans who took the military photos to take military photos) on the Internet showed that on June 29, a J-20 fighter for the high-ridden back version of the yellow skin for testing,After a brief running on the runway, it rose into the air, rushing straight to the clouds, fully showing the powerful thrust of the engine.Some netizens compared the take -off videos of the J -20 at the Zhuhai Air Show in 2022 and the video of the "Wall Climbing Party", and found that the "yellow skin" J -20 sliding running was significantly shortened.In other words, the new test flight of the J-20 was installed with a new power system, which greatly improved the take-off performance of the aircraft short distance and the large elevation angle.

The reason why netizens determine that this new test flight of the J-20 was installed with a turbofan-15 engine, because after the test flight was completed, the relevant personnel directly hit the red banner by the plane, indicating that the J-20 fighter aircraft was the J-20 fighter aircraft was the fighter aircraft.Different from the new model of the active version.Although many words on the banner are blocked by people, the words "15" and "A" are clearly visible, showing that this is a J-20A fighter equipped with a turbofan-15 engine.

The net named "The Tiger of the Cleaning Cleansing Cleansing" was analyzed in the headline today on July 2.And the J-20A of the equipment-10C engine has never shown this take-off method to the outside world.Considering that there is a certain safety risk of the first installed test flight of the new aviation engine, the test pilot generally does not adopt the method of violent test flight at the first flight.This means that the J-20 "drove onion" has already flew leisurely, which can also show that the J-20 was replaced with two new types of engines that have far beyond the turbofan-10C.

On the day of this new type of J-20 flight, the official Weibo account of China ’s aviation industry released a Weibo. The content is that" the early success may not be successful, and the latecomers may not be unreachable.You can't give up your own age. "The picture is the two J-20 fighters.

Some netizens have analyzed that the "early successor" mentioned in this Weibo obviously refers"It indicates that the J-20 has reached the original design indicator.

For a long time, high-performance aviation engines have always been the shortcomings of the Chinese aviation industry. The J-20 has been using Russia's Al-31FN engines in the first flight or even after serving.There is a large gap between the AL-31F engine technology and the US F-119 and the F-135 engine, so that the J-20 fighter cannot be compared with the US F-22 fighter in terms of maneuverability and supersonic cruising capabilities.

In recent years, the J-20 has been replaced with a Chinese domestic turbofan-10C engine. The maneuverability has been improved. It has a preliminary supersonic cruise capacity.J-20 completely get rid of the problem of power system.

This first flight shows that 12 years after the official first flight, the J-20 finally used the exclusive "heart" turbofan-15, and the power system problem that troubled the J-20 for a long time may no longer exist.

Observer.com posted on July 2 that the more surging turbofan-155 will not only comprehensively enhance the mobility of the J-20, greatly extend its supersonic speed, and provide pilots with more optional tasks.profile.Systems such as power supply, cooling, and hydraulic pressure will also obtain unprecedented power redundancy, so that pilots who drove the J -20 "complete body" only need to think about how to better complete the task., And leave sufficient space for future upgrades.

New J-20 also attracted the attention of American media.The US "The Drive" website posted on June 30 that the maximum thrust of the turbofan-15 engine reached 18.5 tons, and the pushing ratio exceeded 10.F-135 engine equipped with F-35 fighter aircraft.At least on the paper, the turbofan -15 may make the thrust of the J-20 more powerful than the two fifth-generation fifth-generation fighters (F-22 "Raptor" and F-35 "Lightning II") even more powerful.

The new "killer" that the Chinese Air Force recently appeared in is not only the new F-20 fighter.CCTV and other official media reported on June 27 the pictures of a number of domestic large -scale drone "double -tailed scorpion" subspecies with bombs and cruise patrols.

Official media disclosed that the "double -tailed scorpion" drone has a range of 8,000 kilometers and the stealth cruise projectiles carried by 1,000 kilometers.

Du Wenlong, a well -known military scholar, explained that "double -tailed scorpion" can bring other small drones, which is the world's first unmanned child's mother machine.This patrol method control method is very high -end. In general, the drone can fly cluster, and the formation flight is amazing.It is a milestone incident for drones to control small drones through the drone.

Although the hidden strategy fighter that Chinese military fans are looking forward to-20 have lost their movement recently, Du Wenlong believes that before the appearance of the H-20, this "double-tailed scorpion" rely on the formation flight, childcare machines currently displayed by the current display,Control, coupled with the range of cruise missiles, once it is needed, the hot seas and locations of Chinese surrounding Chinese, including Guam, are within the strike range.China has a certain strategic curb ability in the air drone.
