Take a note of this and this. The pictures without the hook like structure is an AL-31F on display in an airshow and on the Su-30MKK.

Without doubt , it is AL-31F.this aircraft is often mistaken for a full or final version of J-11B prototype!

powerplant : AL-31F
its flameholder assembly features 3 flameholder rings and some radial interconnectors.

the hook thing looks like the DPI-1500 (ionization sensor)...

maya, I really have a hard time to read your posts. Would you please translate those Russian letters into English?

@ maya & crobato !

Thanks for Your posts even if I'm still not 100% sure ... esp. with the WS-10 equipped testbed (are You sure that this Flanker has its engines removed ??? ... I think I have a clearer picture at home) but as the flying Flanker with boths engines installed shows the difference in length quite clearly !?

Anyway I'm glad taht we agree, that that J-11B with the MAW's is still powered by an AL-31F !

I look at that Flanker now and given the length of the "vanes" I would say that's actually ring that holds the engine. The real engine is not there.

I can't say the difference of length is clear because the petals are folded differently. We do know that a Flanker served as a testbed had both the WS-10A and the AL-31F engines installed. The plane tested the WS-10A by shutting the AL-31F off, letting the WS-10A power the aircraft on its own.

Hmmm ??? I'm still not sure, esp. a that "ring" that holds the AL-31F engine sits much further in front and has a completely different "structure" in comparison to the one with (or without) the WS-10.

Sadly these two pictures are not from the exact same angle ...

You can't have one ring. The J-11 being towed only has one discernible ring. The second ring would have to be the nozzles themselves. And as I said previously, distance by judgment is not trustworthy.

 

[Deino]

...all the operational J-11B fighters and final version of prototypes are using FWS-10 engines .
Please wait for this autumn:china:

Besides that "waiting" for ... how long do You think or expect do we have to wait for the first pirctures of a WS-10-exipped J-10 ??

Cheers, Deino

2月6日，黎阳公司召开党委工作会议， 总经理丁俊在会上对今年的工作进行了了部署，提出了2009年公司军机、科研主攻任务。

会议要求全公司干部职工要以深入开展“三老四严”管理运动为契机，把管理层的作风建设作为一项紧迫的任务，杜绝“一粗二松三不狠、马虎凑合不在乎”的现象。

狠抓基础管理，狠抓现场管理，狠抓管理瓶颈，形成新的管理文化和行之有效的措施办法制度。狠抓质量管理，完善质量体系建设加强产品制造过程中技术难点的攻关力度，确保新机研制和批生产任务完成。要注意充分利用现代化管理手段，用“综合平衡计分卡”来统一各种管理创新工具，在综合平衡计分卡的统一框架下，不断推进精益管理。

会议还提出了“融入中心、开放合作、促进和谐、推动发展”的政治思想工作方针，认真贯彻中航工业“两融、三新、五化、万亿”新的发展战略，确保黎阳公司发展战略目标和年度目标的实现为主线，统筹好企业改革和发展两个大局，发挥政治核心作用和战斗堡垒作用，在改革和发展的征途上取得新的突破。

深入开展好“学习实践科学发展观”活动、“三老四严”管理运动以及建国60周年等系列活动，要把政治工作要融入到新机研制、军品批生产、民品发展、转包生产四大板块中去，实施党建先锋工程保证体系建设、领导班子干部队伍建设、文化建设、工团组织建设和维护稳定五项工作，打造公司软实力，提升企业价值，增强核心竞争力，重塑企业精神，不断鼓舞和激发干部职工团结奋斗的壮志豪情，确保黎阳公司今年的各项生产科研经营任务保质保量完成。

it has a snippet in there that states the goal of 2009 for Guizhou Liyang, is to ensure that development and mass production work needed for the new engine (which I'd assume has to be WS-13) is complete. So, I'm guessing some form of production will start in 2010.

It could also be the WS-12, there was talk a few weeks ago of a major JH-7 upgrade but I guess the WS-13 is a big priority for Guizhou Liyang since I haven't heard of any new RD-93 orders from Russia in awhile.
