The Shenyang WS-10 (Chinese: 涡扇-10; pinyin: Wōshàn-10; literally: "turbofan-10"), codename Taihang, is a turbofan engine designed and built by the People's Republic of China.
The WS-10A reportedly powers the J-11B and the J-16. Unconfirmed reports claim the WS-10A powers some J-10Bs. Unconfirmed reports also claim an improved WS-10A powers the J-11D.
Chinese media claimed 266 engines were manufactured from 2010 to 2012 for the J-11 program. Unofficial estimates placed production at more than 300 units by May 2015.
The WS-10A is advertised as 120–140 kilonewtons (27,000–31,000 lbf) thrust engine. It has Full Authority Digital Engine Control.
The WS-10 was derived from the Woshan WS-6 turbofan, which was abandoned at the start of the 1980s. The WS-10 project was reportedly started by Deng Xiaoping in 1986 to produce an engine comparable to the AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of Aviation Industry Corporation of China (AVIC). The WS-10 may have been based on the core of the CFM-56II (itself based on the General Electric F101); China purchased two CFM-56IIs in the 1980s. China may have spent nearly 20 years developing source code, after being unable to purchase code from Salyut.
The WS-10A, targeted for 130 kilonewtons (29,000 lbf) of thrust, was already in development in 2002. An early version was flown on an J-8II in 2002. In 2004, Russian sources familiar with project reported problems meeting the thrust target; in 2005, they reported problems reducing the weight of the primary and secondary compressors, in addition to problems meeting thrust requirements. Engine testing on the J-11 had already started by 2004, and testing using one engine on the J-11 may have occurred as early as 2002.
