Recently, the Air Force released a promotional video online showing a J-20 fighter . The aircraft is equipped with a WS-10 "Taihang" engine. This is the first time that the Chinese People’s Air Force unit has publicly confirmed that it has a J-20 equipped with a domestic engine to join the sequence. It is believed that in the near future, the J-20 fighters manufactured by our country will be added to the combat force sequence and all domestic engines will be replaced.
Due to the needs of domestically produced third-generation and a half fighters, the Taihang engine has undergone several improvements and modifications. Taihang's modified engine uses advanced technologies such as the FADEC system and single crystal blades. The reliability has been greatly increased, and the thrust has also increased to more than 13 tons. The overall performance has exceeded the earlier introduced Russian AL-31F engine. The aviation industry is also equipped with domestically-made thrust vectoring nozzles on the Taihang improved engine, creating my country's first thrust vectoring engine . Taihang's improved engine can also withstand the test of harsh flight environment, including negligent maneuver and high angle of attack maneuver.

still using AL-31FN-SER3 engines. So, why do Chinese fighter jets need to be replaced with "Taihang" engines? The reason is actually very simple, although the Russian AL-31F engine is also very good and its performance is very stable. But it has two fatal shortcomings, one is high price, and the other is short service life, only 900 hours of flight time. On the other hand, the Chinese Air Force must have its own engines to develop into a truly powerful air force. Prior to this, almost all domestic fighters were dependent on imported AL-31F engines, which made the development of my country's fighter jets somewhat stagnant and very restrained. Therefore, China's aviation engine industry has been working hard to replace the "Tiger" as soon as possible. "Chinese Heart".

equipped with Taihang engine. According to relevant data, Taihang engine is equivalent to F110 turbofan engine. Its air flow can reach 120 kg/s. AL-31F only 110 kg/s, which is slightly less than Taihang engine. Inferior. And the main reason why the WS-10 engine can replace the Russian AL-31 engine is that its service life has increased to 2000-4000 hours. This also further shows that the Air Force’s goal of "one engine and two aircraft" in the 1990s was finally achieved. This was a milestone technological breakthrough for domestic engines.
This time the Air Force’s publicly equipped with the domestically-made J-20 engine is of great significance. This proves that the fifth-generation aircraft of our army has initially solved the "heart disease". It also replaced the follow-up model of the J-20 with a more advanced push-to-weight ratio The domestically produced engine has laid the foundation. It is believed that in the near future, more domestic fighters will be equipped with domestic engines, and my country will completely get rid of its dependence on Russian engines. As a domestic engine that surpasses the Russian AL-31F engine, the Taihang engine also allows the world to see China's strong manufacturing capabilities. Although the WS-10 is not among the top in the world at present, it can be expected in the future that the research and development road of domestic engines is trying to catch up with the world, and the performance of all aspects is gradually improving.
Made in China is about to become an intelligent manufacturing in China! (Gu Minhui)
