As we all know, the most advanced fighter in the world today is the stealth fighter, and the stealth fighter is also known as the fifth-generation aircraft. It has excellent characteristics of "super-maneuverability", "supersonic cruise", "stealth capability" and "over-the-horizon air combat", and can rely on these excellent characteristics to carry out "kicking the door" mission, thereby opening the enemy's first line of defense and eliminating the enemy's fourth-generation aircraft, fifth-generation aircraft, early warning aircraft, etc.
The fifth-generation stealth fighter is very powerful, so many countries want to have the fifth-generation stealth fighter, and many countries around the world have announced plans for the fifth-generation stealth fighter. However, due to the difficulty in the development of fifth-generation stealth fighters and the need to spend a lot of money, the only countries that have really developed fifth-generation stealth fighters are China, the United States, and Russia.
The United States is the first country in the world to install a fifth-generation stealth fighter, and after the F-22 stealth fighter came out, it allowed countries around the world to see the power of the fifth-generation stealth fighter. After the F-22 stealth fighter was installed in the US military, it can be said to be invincible in the world and has become the core weapon and equipment for the United States to seize air supremacy. However, with the advent of the Chinese J-20 stealth fighter, the myth of the first F-22 stealth fighter will be ended.
Speaking of the mainland's J-20 stealth fighter, the aircraft, also known as "Weilong", is a single-seat, twin-engine, duck aerodynamic layout heavy-duty fifth-generation stealth fighter produced by AVIC Chengdu Industrial Group. The J-20 stealth fighter was officially announced as a troop in 2018, and after the deployment of the troops, foreign media have been reporting the shortcomings of the J-20 stealth fighter, saying that the engine equipped with the J-20 seriously affects the performance, and its combat power is not as good as the American F-22 stealth fighter.
In fact, after the advent of the J-20 stealth fighter, it was indeed troubled by the engine, and the early J-20 stealth fighter used the AL-31F engine purchased from Russia, which is only the engine equipped with the fourth-generation aircraft, and its thrust is small, making it difficult for the J-20 to exert its maximum combat power. With the rise of the mainland's domestic Taihang engine, the J-20 stealth fighter has also been replaced with a domestic Taihang improved engine, but compared with the F119-PW-100 vector engine equipped with the American F-22 fighter, there is still a big gap.
In order to solve the problem of heart disease of the J-20 stealth fighter, Continental has developed an engine specifically for the J-20, that is, the turbofan-15 engine. Some time ago, Daniel Zhang, the project leader of AECC Beijing Institute of Aeronautical Materials, said that the new aircraft engine completely independently developed by the mainland, code-named "Emei" turbofan-15, has officially entered the mass production stage. This also shows that the J-20 stealth fighter is not far away from replacing the turbofan-15 engine.
Recently, the J-20 stealth fighter finally ushered in the strongest heart, that is, the turbofan-15 engine. At 3:35 p.m. on June 29, the mainland's first J-20 improved fighter equipped with two turbofan-15 high-thrust engines successfully conducted a test flight at a test flight base, which also marked that the J-20 stealth fighter finally ushered in a matching engine, and the final shortcomings of the J-20 stealth fighter will also be filled.
According to the video exposed by netizens, the J-20 prototype took only a little more than 16 seconds from taxiing to takeoff when it first flew, and the taxiing takeoff time was controlled at about 10 seconds after being equipped with the turbofan-15 engine, which is enough to show the advanced turbofan-15 engine. The J-20 stealth fighter equipped with turbofan-15 engines will take off faster and become more powerful.
It is reported that the turbofan-15 engine adopts an advanced double-redundancy full-authority digital electronic control system and a vector tail nozzle, which has advanced fault isolation functions. Its maximum thrust will be between 18 tons and 19 tons, it can be said that the thrust of the turbofan-15 engine is far more than the F119-PW-100 vector engine equipped with the American F-22 fighter, and the maximum thrust of the American F119-PW-100 vector engine is less than 16 tons.
Since the thrust of a turbofan-15 engine reaches more than 18 tons, the thrust of the J-20 stealth fighter using two turbofan-15 engines can reach more than 36 tons, and the power of the J-20 at this time is stronger than that of the American F-22 fighter. The J-20 stealth fighter equipped with turbofan-15 engines will be faster and more maneuverable. It is reported that the maximum speed of the J-20 stealth fighter without afterburner is more than Mach 2.2, and after driving supersonic cruising, the speed is faster, and it can reach Mach 2.8 and can efficiently reach the battlefield.
In general, the J-20 stealth fighter was equipped with turbofan-15 engines for its first flight, which is not only a major breakthrough and milestone in the mainland aviation industry, but also allows the mainland to solve the problem of heart disease of the J-20 stealth fighter. It also proves the strong strength of AVIC technology in the world. There is nothing difficult in the world, as long as you are willing to climb! In short, the J-20 stealth fighter equipped with turbofan-15 engine will completely surpass the F-22A fighter of the US military in terms of performance, becoming the world's most comprehensive performance of the fifth-generation heavy stealth fighter.
