The WS-20 (Chinese: 涡扇-20; pinyin: Wōshàn-20; lit. 'turbofan-20') is a high-bypass turbofan being developed to power the Y-20 strategic airlifter, based on the core of the low-bypass turbofan Shenyang WS-10A.[1]

With a thrust range of 12,000–14,000 kilograms-force (120,000–140,000 N; 26,000–31,000 lbf), the WS-20 has been flying on an Il-76 test aircraft since 2014,[2] and a few years later an internet photo has revealed an Il-76 test platform being equipped with 4 WS-20s.[3] Although originally projected to enter production in 2016,[4] the progress was much slower, it was not until February 2019 when a Xian Y-20 with serial number 783 was equipped with a single WS-20 for testing.[3] The testing continued in 2020 and 2021.
