Our Best Look At China’s Re-Engined Y-20B Cargo Jet [...]

New video has emerged of the latest, re-engined version of China’s Xi’an Y-20 military transport aircraft. The Y-20B, which is powered by the domestically produced WS-20 high-bypass turbofan engine, is a significant development compared to the earlier models, which relied on Russian-supplied Soloviev D-30KP-2 engines. What’s more, there are now indications that the improved Y-20B may now be in operational service with the People’s Liberation Army Air Force, or PLAAF. [...]

As to the claims that the Y-20B is now operational with the PLAAF, that certainly seems possible, although the aircraft in the video lacks serial numbers, so it could also be a pre-series example being used for operational trials. On the other hand, such identification markings could have been obscured for the type’s public appearance. [...]

In terms of output, the WS-20 is expected to produce around 31,000 pounds of thrust, compared to 26,450 pounds for the D-30KP-2, which equips the original Y-20A, which first entered operational service in 2016. Low-bypass engines, like the D-30KP-2 don’t produce the same level of thrust as high-bypass units of similar size and, furthermore, are significantly less efficient.
