Perhabs things dont work as simple as you think. Aircraft engines are a highly complex technology not only in design but in materials too.Can someone explain why high-bypass turbofans (ie. WS-20, WS-18, CFM Leap) are seemingly harder to develop and produce than low-bypass turbofans like the WS-10?
Don't high by-pass turbofans use the same core as low-bypass turbofans? It shouldn't be too hard to stick a large fan to the WS-10? If the core is the same as the WS-10, why is the WS-20 taking so long to be finished?
Aero engine take a long time to mature on average 20 to 30 years. China come late very late in the engine engineering Don't forget that Chinese university only reopen in 1980's due to political chaos. Western country has been developing aero engine since WWII and have collaboration effort from all the countries in the western world. Add to that the technical embargo etc make it even harder for China to develop She has to do everything herself with no collaboration with any other country. Unlike Japan or India heck even with all the assistance from Russia, US, French India has yet to produce high thrust engine. So there you goPerhabs things dont work as simple as you think. Aircraft engines are a highly complex technology not only in design but in materials too.
Its no surprising that china has been having a lot of dificulties in developing aircraft engines.
Yup talking from his rear NO CHINA DOES NOT HAVE DIFFICULTIES HERE IS THE LATESTWS-20 is an engine for military use. Even so, china is having serious dificulties in getting it into service.
