I personally think that China is taking extra pre-cautions to regarding the endurance and quality of its WS-10. The fact they have equipped them on the production J-15 means they are not failure and rather trustworthy. However unlike the j-15, J-10b is a single engine aircraft, since it a new variant their engineers probably want to evaluate it first on a the 2 engine J-15 and isolate any problem that may develop solely on the J-10B design rather than weighing possible causes from the WS-10.So much for the supposed improvements in Chinese jet engine manufacturing.
