TheWS-13(Chinese:Oa phiến -13), codenameTaishan,is aturbofanengine designed and manufactured byGuizhou Aircraft Industry Corporationto power theCAC/PAC JF-17 Thunderlightweightmultirole fighterjointly developed by China and Pakistan, and in the near future theShenyang FC-31fifth-generationstealth fightercurrently under development.
Design and development
[edit]China began development of the Taishan in 2000 to create a domestic engine for replacing theKlimov RD-93turbofan, which had been selected in the 1990s to power the JF-17 lightweight fighter. It is designed to produce 86 kN (19,000 lb) of thrust withafterburnerand have a life span of 2,200 hours; an improved version providing up to 93 kN (21,000 lb) of thrust with afterburner was also developed.[1][2]
The WS-13 Taishan was certified in 2007 and serial production began in 2009.[citation needed]The 18 March 2010 edition of theHKB Reportstated that a JF-17 equipped with the WS-13 completed its first successful runway taxi test.[3]
Officials at theFarnborough International Airshowin August 2010 stated that a JF-17 was being test flown with a Chinese engine, likely the WS-13.[4]In November 2012,Aviation Week & Space Technologyreported that flight testing on the JF-17 was underway in China.[5]It was reported at the 2015Paris Air Showthat testing was continuing.[6]
Guizhou is developing a new engine, designated theWS-19that fits in the same footprint as the WS-13 but is a wholly new design that incorporates the same technology as theXian WS-15.The WS-19 is the intended engine for production versions of theShenyang FC-31medium-size stealth fighter such as the J-35 for aircraft carriers.[2]
