From my understanding, The guy was talking about the reliability problem with WS-10. Something about the compressor blade breaking (I think it's the first stage HP compressor)

I dont understand chinese, but this video was posted on youtube on 23-07-2020 (seems that CCTV has a channel in youtube, despite the fact that AFAIK youtube is blocked in china). After all these years, is WS-10 still having problems like that?

Dude the 606 indivdiual was clearly referring to when the WS-10 was first beginning production ... do you not understand that a documentary can be (and usually is) referring to events which occurred in the past o_O?

Again, i dont understand chinese. So i thought that the information was recent.

Someone on Weibo asked Pupu if the WS-15 has a thrust of 18 tonnes, as stated by Song Xinzhi. He says he would believe the 18 tonne figure if it was the long term goal of the WS-15 (mentioning the 117S and the WS-10C as evolutions of the AL-31F and WS-10 engines respectively to compare with). Pupu also mentions that the WS-15 thrust should be a little over 16 tonnes at the current stage. It would be interesting to see if this pans out to be true. Nonetheless, at least we finally have a little more information on the WS-15.

Pupu also says 裤衩还是稍微红了那么一点点 (the pants are still a little red), in response to another poster saying he would feel ok if the thrust is 16.5 tonnes. Does this mean Pupu is saying the WS-15 thrust is slightly under 16.5 tonnes?

Keep in mind when Pupu first talked about the J-20’s WS-10s he suggested they were 13.2 tonne engines. More recently he’s suggested they’re 14.5 tonne engines. This tells me Pupu’s own information isn’t always up to date, which is something he himself has attested to before...

Saw this over at PDF, guy says WS-19 is 10:1 10ton thrust?

The guy is Song Xinshi and he was apparently a fighter pilot (and therefore is appraised to be reliable by some in the cjbd forum (?) ).


" WS-19 thrust ratio exceeds 10, and its thrust exceeds 10 tons, instead of the 9,500 kilograms previously transmitted online."

"The channel ratio of turbofan 19 transmitted on the Internet may be wrong and not so large"

All this from a Chinese tube video btw.

So the implication is that it's around 16.1 tons, or around 158 kN (note the F119 is around 160 kN).

This is dated 2016. CJ-1000 LPT shaft is Norwegian in origin?

Pardons if this was common knowledge.
Also, what's the difference between CJ-1000A and CJ-1000X?
