The WS-13 (Chinese: 涡扇-13), codename Taishan, is a turbofan engine designed and manufactured by Guizhou Aircraft Industry Corporation to power the Pakistan-China jointly developed CAC/PAC JF-17 Thunder light-weight multi-role fighter, and in the near future the Shenyang J-31 fifth generation stealth fighter currently under development.

Design and development

China began development of the Taishan in 2000 to replace the Klimov RD-93 turbofan, which had been selected in the 1990s to power the JF-17 light-weight fighter. It is designed to have a life span of 2,200 hours and an improved version, providing around 100 kN (22,450 lb) of thrust with afterburner, is under development.[1]

The WS-13 Taishan was certified in 2007 and serial production began in 2009.[citation needed] The 18 March 2010 edition of the HKB report stated that a FC-1 equipped with the WS-13 completed its first successful runway taxi test.[2]

Officials at the Farnborough International Airshow in August 2010 stated that a JF-17 was being test flown with a Chinese engine, likely the WS-13.[3] In November 2012, Aviation Week reported that flight testing on the JF-17 was underway in China.[4] It was reported at the 2015 Paris Air Show that testing was continuing.[5]
