I think what they mean is WS-10=test version
FWS-10=WS-10A=Version for J-11 and J-10.
it is likely Ws-10 is refering to development model,while WS-10A refering to production model.
Will WS-10A will power J-15,or complete different variant of WS-10?

and hopefully I did understand it:


WS-10 = the original version, which was later redesigned/modified into ...
FWS-10 = the version for the J-11B
FWS-10A = the version for the J-10 (B ??)

Thanks in advance, Deino
[ 发动机 fādòngjī ] letteraly means "the Machine(机) that SendsMotion(发动) "

WS stands for [ 涡扇 wōshàn ]
涡 is the contraction of [ 涡轮机 wōlúnjī ] meaning "turbine"
扇 is the contraction of [ 风扇 fēngshàn ] meaning "ventilator" or "fan"

Put all these things together and you've got [ 涡轮风扇发动机 ] more commonly known as [ 涡扇发动机 WōShànFādòngjī WSF] alias Turbofan Engine.

I Think they put FWS instead of WSF just because it's more convenient when you classify different types of engines on an alphabetical table.

Re: Ws10a

Fadonji basically means engine here.

Re: Ws10a

3 level heirarchy typical of Chinese military designations:
First level is what kind of thing is it? An engine-- F
Second level is what kind of engine is it? A turbine-- W
Third level is what kind of turbine is it? A fan type -- S (versus jet type--P)

another example is ZTZ (armored vehicle, tank, main battle tank)

Cheers for that!

You have plucked a thorn out of my mind, as I've been confused by the ZTZ designation for ages

That also explains why no engine gets the first letter "F" unless they got deployed by PLAAF. WS10 might be a test engine before the end product FWS10/WS10A after all.

Question Re: Ws10a

Thanks for all the exolanations ... but why the "F" now only with the WS-10 ??

Also the other "engines" are engines and the letter "F" could have been used in other types too like FWP-14 for the Kunlun or FWS-9 !

Re: Ws10a

My guess is official designations versus manufacturer's own names, which may be used more commonly.

There is another possibility---the letter "F" doesn't mean Fadongji at all. It may be the initial letter of Chinese word "Fan" (means "reverse" or "opposite"). That means in a dual-engine plane, designers may make the two engines revolving in reverse direction each other so they can balance the torque caused by the revolving of engines. Or they may fix different accessories respectively on the left or the right engines with different positions to make the maintenance (without dismantling the engines but via the openings of fuselage) convenient.

In short, if WS-10 is assumed to be mounted on the left of the fuselage of a J-11, FWS-10 will be the one on the right.

There are rumors that the right engine and the left engine of WS-9 on JH-7 and WP-14 on J-8B are exchangeable like western fighters. But J-11 is based on Russian design, so it may be different.

中国三代战机发动机再制造技术达到国际先进水平
2010年07月28日 18:37 来源:中国新闻网 

  中新社北京7月28日电 (杨春源 李翔 陶社兰)解放军第5719工厂自主创新三代飞机发动机关键部件再制造技术,突破了由少数西方国家对航空发动 机再制造技术的垄断,使三代战机的发动机寿命从900小时延长到1500小时。

  偏居成都平原一个小镇上的5719工厂,是隶属于空军装备部的装备保障性企业,担负着军用航空发动机修 理保障的重任。这个仅有2000多人的普通空军装备修理企业,短短几年间完成63项科研成果,20多项获得 国家、军队科技进步奖,自主创新的军用航空发动机再制造技术达到国际先进水平;发动机修理能力成倍增长,2 004年总资产才11个亿,6年后就达到29个亿,资产增长超过263%。

  2004年,某新型航空发动机维修线刚刚建成,航空兵部队一批发动机进厂急待维修。如何快速形成新型发 动机批量修理能力?

  工厂拿出的第一个举措,是打破旧有的生产模式和利益格局,进行彻底的生产流程再造。经过8个月的重新调 配修理资源、改革修理流程,修理能力显著提升,某型发动机平均修理周期降幅达27.3%。此后,他们根据部 队保障任务的变化,对流程进行持续改进、优化,修理能力每年增长率达60%以上,先后实现了由维修二代机向 三代机、由单机种、大批量维修向多机种、小批量维修的跨越。

  随着大批新型航空装备在部队列装,新型军用航空发动机关键、重要零部件供应,逐渐成为制约空军战斗力持 续生成的突出问题。工厂专门组织精兵强将集中攻关,自主创新了21项具有国际先进水平的三代飞机发动机关键 部件再制造技术,突破了由少数西方国家对航空发动机再制造技术的垄断,使空军三代战机的发动机寿命从900 小时延长到1500小时,相当于使1台发动机发挥了1.6台发动机的作用,取得了巨大的国防军事、经济和社 会效益。

  质量是航空发动机维修的生命线。为了确保维修质量“零缺陷、出精品”,从2005年开始,5719厂采 取设立“质量警示墙”、质量建设大讨论等多种形式,引导职工在质量工作上不断强化瞄准一流、追求卓越的意识 。在那道89米长的质量警示墙上,空军历史上的每一起等级飞行事故和地面事故,工厂历史上发生的10多起较 大质量问题,等等,赫然在目。“文化铸魂”引领了维修质量的提升,工厂至今修理的发动机不计其数,已连续1 4年未发生因工厂责任造成的等级飞行事故。(完)
talks about factory 5719, which is located in Sichuan, doing MRO for a new 3rd generation engine (I think AL-31FN). It says that their work allows the service life of the engine to be extended from 900 hours to 1500 hours.

Re: Ws10a

Articles describes China has mastered the WS10A technique to prolong the lifespan of the engine, it's already superior to Russian's AL31F. The lifespan of WS10A is now at 3x times of the AL31F.

It does sound legit. not some BS stuffs.

Wouldn't suprise me as most Soviet/Russian hardware wasn't made to last, it was mean't to be cheap and once service life was up, simply replace it.

Well, it was meant to be used in a war where the expected lifetime of the aircraft was measured in hours. No point gold-plating a pawn you expect to sacrifice... Just a different doctrine.
