歼 20 Do you want to change?Domestic Air China has achieved a new breakthrough, and the thrust is greater.

At last year, my country's fighters continued to successfully spread, especially 歼 20, not only on the domestic engine entered the mass production state, and there was a double version of 歼 20. And in this year, there is a good news, that is, my country is conducting a new round of engine testing. This is very likely to represent the "China Heart" again. Because there is news report, China's歼 20 engines have been continuously improved. Although the 歼 20 replaced the turntile engine, this fighter truly became a domestic fighter, but compared with the US F-22 engine, there is a great gap, in order to make up for this gap, my country Researchers have been studying the engine of the 歼 20, and the new test of this domestic engine is very likely to prepare for the engine for 20.

歼 20 The turnt fan 10 is now equipped, although the original equipped AL-31F engine, the thrust has greatly improved, but it is still not allowed to complete its combat power for 歼 20, so this is Become some people say that 歼 20 is not as good as the US F22 and F35, if the combat power of the 歼 20 is 1, then it is limited by the engine limit, and the F22 and F-35 of the United States even It is the combat power only 0.8 that can also play all the strength. Therefore, in order to enable 歼 20 to complete its strength, it is necessary to completely solve the problem of the engine.

Compared with the 20, the engine used by the F22 is a F119 turbofan engine. It is a two-dimensional vector nozzle that can be up and down, and the maximum thrust reaches 15.6 tons, and the thrust of the F135 engine used by F35 has reached 18 tons; and Compared to the 歼 20, the thrust of the turntile 10 engine is much lower, and this gap leads to the flight speed of the fighter, and the climb is greatly affected.

However, my country can do this is also very difficult, after all, as an absolute cutting-edge field, major countries have a confidentiality to its technology, and the United States is worried about my country's technology. The sanctions have been implemented, and the possibility of adopting advanced avionics technology in my country. In this way, the engine that my country can obtain is the engine on the fighters who are retired, or it is the engine on some civil airplanes, which is completely unable to meet the requirements compared to my country's fighter research and development.

The most typical example is the screaming 7. In the last century, the fighter is now produced, but its engine has always had a problem, delaying a lot of project progress, forced to have a helpless. Buy more than 80 retired "Sibbe" engines to the UK. When these engines arrive, my country is the result of more than 20 scraps inside, only 55 can be used, and this engine is the only power source of the fighter. my country has also understood the importance of the engine and started to vigorously develop its own engine until the turntile engine appears to get rid of the "card neck" limit.

But even if my country's engine is still behind others, just like the scroll fan 10 of the 20, it is the core technology source is the US CFM-56 core machine. This engine is developing in the United States in the last century. A civil engine, my country has led to its technology and continuously improved, there are multiple different versions such as scroll fans a, b, but subject to the original design idea, which is the most advanced F119, F135 engine in the United States. Compared to the moreover gaps.

Therefore, at this time, the importance of the vortex 15 is highlighted. As a engine that truly belongs to our country, it is a small conversation vector vortex engine that is specifically developed for the five generations of my country. It must be stronger than the vortex fan, its thrust reaches 177 kWh, the fuel ratio reached 11, has exceeded the 119 engine of the F22, and the F35 F135 engine is not up and down. After the engine is equipped with this engine, its combat power will be fully played, and it will make up for the defects in ultraphi dynamics, becoming a true five generations of F22 enemy, and can even rely on the United States. The backward advantage is crushed.

According to the R & D speed of my country's engine, the turnt fan 10 The engine has spent nearly 30 years, and the turntile has the first experience paving, and the time should be around 20 years, while A vortex 15 engine is successful in 2005, which is almost the time that the time is almost the time; therefore this time the 歼 20 new round engine test, it is likely to carry out the turntable turntile 15 engine test.
