The Shenyang WS-10 (Chinese: 涡扇-10; pinyin: woshan-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.[1] Unconfirmed reports claim the WS-10A powers some J-10B's.[2] Unconfirmed reports also claim an improved WS-10A powers the J-11D.[3]

Chinese media claims 266 engines were manufactured from 2010 to 2012 for the J-11 program.[4]

Description

The WS-10A has a reported thrust of Script error: No such module "convert". and a 7.5:1 thrust-to-weight ratio. It has Full Authority Digital Engine Control.[5]

Development

The WS-10 was derived from the WS-6 turbofan, which was abandoned at the start of the 1980s.[6] 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).[5] 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-56II's int he 1980's.[7]

The WS-10A, targeted for Script error: No such module "convert". of thrust,[5] was already in development in 2002.[8] In 2004, Russian sources familiar with project reported problems meeting the thrust target;[9] in 2005, they reported problems reducing the weight of the primary and secondary compressors, in addition to problems meeting thrust requirements.[10] Engine testing on the J-11 had already started by 2004,[9] and testing using one engine on the J-11 may have occurred as early as 2002.[8]

A full-scale WS-10A engine was first seen at the 2008 China International Aviation & Aerospace Exhibition.[5]

In 2009, Western media reported that the WS-10A approached the performance of the Saturn AL-31, but took much longer than the AL-31 to develop thrust.[11] Furthermore, reportedly the engine only generated Script error: No such module "convert". of thrust.[5] In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory.[12] 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.[13] 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.[14]

The WS-10A reportedly matured enough after 2009 to power the J-11B Block 02 aircraft.[15] A WS-10A-powered J-10B was seen in July 2011, but the engine did not power the initial J-10B production batch, possibly because of production or performance issues.[3]

WS-20

The WS-20 is a high-bypass engine[3] reportedly producing 14 tons of thrust.[16] It is believed to be based on the core of the Ws-10A.[5][17]

The WS-20 was first seen in January 2014 while being tested on an Il-76,[3] and is believed to be intended for the Y-20 strategic airlifter.[16]
