The WS-20 (Chinese: 涡扇-20; pinyin: Wōshàn-20; literally: "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 is projected to enter production in 2016.[3]
