Chinese Aero Engine information thread

is DD5 employed in latest variant of taihang?

i am not sure, but as daokou says:

这个时间段恰恰也是中国开始解决单晶叶片的时候，而且正好赶上了太行涡扇十的研制。应该说，中国的太行发动机赶上了好时候。中国发展的单晶材料一直从DD3到DD9（有网友纠正我说的只到DD6），DD3就是“定向铸造单晶第三号材料”的意思。
林左鸣林董在《对话》里拿出来的可以耐2000度高温的就不知道是DD多少了，反正美俄现在还没有能耐这么高温度的单晶叶片，美国的F135发动机被小白和喷子说成耐高温到了丧心病狂的程度也就是可耐高温1700度，意思是我们中国根本赶不上，那林董拿的耐2000度的岂不是打脸吗？

这幅图上许多人并没有发现应该发现的秘密，就是为什么工作人员要给这台2014年珠海航展展出的14吨的太行涡扇十的管路上刷漆？
很简单，参展商告诉你的意思是，这是一台使用过的发动机，也就是说这台太行已经过火了，工作过了。这意思还不明白吗？在高温下烤过的管路颜色不美观，刷刷漆遮着。我眼神不好，伸长脖子看了半天，确实有用过的痕迹，这说明这台太行发动机已经是定型机，按照我们中国人的传统，凡是展出的就有更好的在研制。特别说明，第二张图和第三张图都是我在2014年珠海航展上照的14吨太行发动机，注意第三张14吨太行使用过的痕迹？

What type this engines?

Hybrid home grown engine. (Mix of AL-31F and WS-10 technology)

He mention it not only once but twice and stress on the term 国产. I dare to bet PLAAF chief might have told him something juicy which we commoner will not know regarding J-20 development. Yin Zhuo is a high ranking CPC board member plus ex rear admiral rank. His level to classify data will be much higher than rest.

The rest of his speech during the interview is also consistent with what many military watcher conclude that WS-15 engine has not install on J-20 but he claim 'soon'. Without WS-15, PLAAF military jet engine will still be a generation behind USAF. He commented.

@Grandy

We had this discussion here already "ad nauseum" and there are actually two parties here: The one side which is jumping high o the bandwagon that the J-20 uses a WS-10, or already WS-15 or - IMO the most unlikely version - a hybrid engine using the WS-10's core mated with the AL-31FN's nozzle.

For the other side is confirmed that it is an AL-31N since all evidence and external details confirm this: it looks like this engine, Saturn and CAC have a long established relationship and latest reports confirm this too.

If You are interested, this might be worth a read for You:

Bu please take Your time and read a bit the arguments of both sides and come to Your own conclusion.

Honestly I'm glad to notice a subtle change in Your attitude: At least You no longer pretend it IS a WS-10 and even more a WS-15. I remember some very harsh words from You after my reply to Your claims where You repeatedly pretend the J-20 is already flying with WS-15.

Anyway ... I'm still very much sceptical about Your theory of a MIX, since this is technical impossible or at last not logical: To add an AL-31FN's nozzle on a WS-10 is plain stupid esp. if the WS-10 is itself an efficiently working engine. That does not exclude that this latest specialised AL-31FN might use certain WS-10 technology, but it is still an AL-31FN.

IMO the most likely version which would also explain these reports about an indigenous engine is, hat it is plain and simple a special custom-tailored version jointly-developed and esp. China-funded version, that is PR-wise speaking a "Chinese" engine, but strictly spoken it s a development of the AL-31FN of some sort.

It doesn't matter it's has AL-31F or whatever. Most importantly is from even a single screw on it is 100% made in China. And we can do whatever we want.

Let me make a prediction. If Type001A carrier commission and carry the combat ready J-15A with WS-10A engine all install in it. I can deduct something.

Until that day, I will still say we are behind. Until we have our own marine propulsion be it electric or gas, until we have our own aero engine, we are still behind. And there is nothing wrong with that, just keep quiet and observe and monitor. No need to claim anything. China is famous for being quiet and then booom suddenly suprise the shit out of the world.

I remember the day Sunway Taihulight was unveiled, not a single sound and suddenly booom, when the J20 was unveiled, nobody knew anything about it, the Indies were even saying it's fake and it's photoshopped.

Goodbye! WS-10 chief designer, Zhang Erhe.

According to "Jane's defense weekly" Chinese and Ukrainian to set up a join venture Engines factory in Chongqing
Which will be including D-136, MS-500V and TV3-117VMA-SBM1V helicopter turboshaft engine, AI-450S general aviation aircraft engine, D436-148FM and D -18T high bypass ratio turbofan engine, D-27 counter-rotating turboprop engine, and AI-222 series military jet engines, even the MS-400 engine for cruise missile is included
英国《简氏防务周刊》网7日报道称，2016年中国航展上传来消息，马达西奇公司根据本年与中国企业签订一项成立合资公司的协议，授权在中国生产公司旗下多款航空发动机，这一系列发动机将在重庆市新建厂房内进行组装，其中包括D-136、MS-500V和TV3-117VMA-SBM1V直升机用涡轴发动机，AI-450S通用航空飞机发动机，D436-148FM和D-18T高涵道比涡轮风扇发动机，D-27对转涡轮螺旋桨发动机，以及AI-222系列军用喷气发动机。环球网报道指，就连巡航导弹搭载的MS-400涡扇引擎也在“国产”发动机之列。

I have heard WS13E will be capable of super cruise, is it correct?

supercruise ability is co related with jet design also but ws13e +fc31v2 will be designated as super cruise

99A和VT4坦克分别装备1500马力和1300马力的CH1000传动装置。

Is this the complete power pack with the transmission ?
Also 0-32 kmh in 6 seconds seems to be the norm for Western tanks.
