Mil.huanqiu.com has a report today on the progress of the development and assembly of China’s homegrown engine for its most advanced stealth fighter J-20, which is said to lack engines powerful enough to achieve its designed advantages. No one in the world is willing to sell such powerful engine so that China has to develop its homegrown powerful engine for J-20.
According to the report, CCTV reporters have recently visited the assembly factory of AECC Shenyang Liming Group Co., Ltd. that develops and assemblies WS-15 Emei turbofan for J-20. There was report that WS-15 is more powerful than all its foreign counterparts, but its details remain China’s top secret.
However, CCTV has been able to take 15 photos of the top secret engine and its assembly factory, three of which are shown on top of this post.
The report only reveals that the internal workings of an aircraft engine (not specifically WS-15) are very complicated being made up of over 10,000 precision parts and that the quality of the assembly as the final step in producing an aircraft engine (not specifically WS-15) to a major extent affects the quality of the engine.
