Shenyang WS-10
The Shenyang WS-10 (Chinese: 涡扇-10; pinyin: Wōshàn-10; lit. 'turbofan-10'), codename Taihang, is a turbofan engine designed and built by the People's Republic of China.
Chinese media reported 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 an engine with 120–140 kilonewtons (27,000–31,000 lbf) thrust. It has full authority digital engine control (FADEC).
The WS-10 is reverse engineered from the CFM56 with the experience gained from the Woshan WS-6 turbofan project, 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 Saturn AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of the Aviation Industry Corporation of China (AVIC). Initial production models suffered quality issues from the early direct use of AL-31 control systems. Furthermore, Salyut refused to sell the control system source code, forcing China to spend nearly 20 years developing its own code independently. An early version of the FADEC flew on an J-8II in 2002.
The WS-10A, targeted for 130 kilonewtons (29,000 lbf) of thrust, was already in development 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.
A full-scale WS-10A engine was first seen at the 2008 China International Aviation & Aerospace Exhibition.
In 2009, Western media claim that the WS-10A approached the performance of the AL-31, but took much longer than the AL-31 to develop thrust. Furthermore, the engine reportedly only generated 110–125 kilonewtons (25,000–28,000 lbf) of thrust. In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory. In 2010, it was reported that reliability was also poor; the WS-10A lasted only 30 hours, while the AL-31 needed refurbishing after 400 hours. The quality problems encountered with the WS-10A reflected the state of the Chinese aerospace industry. AVIC initiated a general effort to improve quality control throughout its production chain in 2011.
The WS-10A reportedly matured enough after 2009 to power the twin-engined J-11B Block 02 aircraft. Production or performance issues may have prevented the WS-10A from powering the single-engined J-10B. In 2018, Chinese state media reported an increase in engine lifespan from 800 to 1,500 hours due to the increased heat resistance of new third-generation single-crystal turbine blades.
