Developed from CFM International CFM56/General Electric F101
Developed into Shenyang WS-20

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.[2] Unofficial estimates placed production at more than 300 units by May 2015.[1]

Description

The WS-10A is advertised as 120–140 kilonewtons (27,000–31,000 lbf) thrust engine.[1] It has full authority digital engine control (FADEC).[3]

Development

The WS-10 is derived from the CFM56 with the experience gained from the Woshan WS-6 turbofan project, which was abandoned at the start of the 1980s.[4] 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).[3] 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 before the arms embargo.[5] After being unable to purchase source code from Salyut, China spent nearly 20 years developing its own source code for the WS-10 engine.[1]

The WS-10A, targeted for 130 kilonewtons (29,000 lbf) of thrust,[3] was already in development in 2002.[6] An early version flew on an J-8II in 2002.[1] In 2004, Russian sources familiar with project reported problems meeting the thrust target;[7] in 2005, they reported problems reducing the weight of the primary and secondary compressors, in addition to problems meeting thrust requirements.[8] Engine testing on the J-11 had already started by 2004,[7] and testing using one engine on the J-11 may have occurred as early as 2002.[6]

A full-scale WS-10A engine was first seen at the 2008 China International Aviation & Aerospace Exhibition.[3]

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.[9] Furthermore, the engine reportedly only generated 110–125 kilonewtons (25,000–28,000 lbf) of thrust.[3] In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory.[10] 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.[11] 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.[12]

The WS-10A reportedly matured enough after 2009 to power the J-11B Block 02 aircraft.[13] Production or performance issues may have prevented the WS-10A from powering the J-10B.[14] 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.[15]

In March 2020, Chinese state media released a video showing a WS-10B-powered J-10C; aircraft markings suggest it was part of the fourth batch of J-10Cs for the PLAAF.[16]

WS-20 (WS-188)

Main article: Shenyang WS-20

The Shenyang WS-20 (WS-188)[17] is a high-bypass engine[14] reportedly producing 13.8 tons of thrust.[18] It is believed to be based on the core of the WS-10A.[3][19]

The Shenyang WS-20 was first seen in January 2014 while being tested on an Il-76,[17] and is believed to be intended for the Y-20 strategic airlifter.[18]

Thrust vectoring

A testbed J-10B powered by a WS-10 with thrust vectoring (TVC) - called "WS-10B-3" by Jamie Hunter - was demonstrated at the 2018 China International Aviation & Aerospace Exhibition.[20] The TVC nozzle uses actuator-assisted moving petals, similar in concept to General Electric's axisymmetric vectoring exhaust nozzle (AVEN) and Pratt & Whitney's pitch-yaw balance beam nozzle (PYBBN).[21]

Variants

  • WS-10 - base variant for testing and initial production.
  • WS-10A – improved variant; advertised to have 120–140 kilonewtons (27,000–31,000 lbf) of thrust[1]
  • WS-10B – improved variant with greater reliability and thrust; based on the WS-10A[22]
  • WS-10B-3 – TVC variant[20]
  • WS-10C[20]
  • WS-10G – thrust vectoring variant[23] generating 152–155 kilonewtons (34,000–35,000 lbf) of thrust during testing[3]; intended for the Chengdu J-20[23]
  • WS-20 – high-bypass derivative for the Y-20 transport; 138 kilonewtons (31,000 lbf) of thrust[18]
  • QD70 – 7MW class gas turbine engine developed from WS-10 for industrial & naval applications[24]
