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?
Perhabs 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.
WS-20 is an engine for military use. Even so, china is having serious dificulties in getting it into service.
Yup talking from his rear NO CHINA DOES NOT HAVE DIFFICULTIES HERE IS THE LATEST
