Chinese Engine Development

[siegecrossbow]

What is the current thrust of WS-10A? I was under the impression it’s 130 kN or so. Is the current service life figure of 2,000 hours and MTBO of 1,200 hours accurate? Basically I would like to know when the current WS-10A entered operational service.

WS-10A is only used for J-11B and early batch of J-16 if I am not mistaken. WS-10B increased thrust by around 15 percent off the WS-10 baseline according to a Chinese research article.

The best way to get data on engine is wait for one of the Pakistanis J-10C pilots to slip up during an interview.

Does this mean the CJ-1000A's development is at a more advanced stage than we used to think here?

It does give me the same vibe as the push of C-919 certification work at the beginning of 2022.

According to the Jetliner (大飞机) magazine, which is published by COMAC, the design of AEP500 turboprop (5000+ KW or 6700+ hp) was finalized in 2021, and small-batch production has begun. The article also mentions that WJ-6E turboprop has reached an output of 6000+ hp. Both engines are available for the MA700 airliner, with the WJ-6E being the backup option. The article also confirms that MA700's maiden flight took place in April 2022, although it doesn't state which engines it flew with.

最新型的涡扇6E as another backup, WOW. The WS-6 designation was first given to engine to power J-8 and J-7 in the 1960s.

I’m trying to get an idea of where the Chinese stand on military turbofan development and technology, and if WS-10A is about analogous to AL-31FM1 and WS-10C is about analogous to AL-31FM2, then it gives a rough estimate of where Chinese engine technology levels were at that time. I think when WS-10A and WS-10C were reliable enough to put into service, it would mean China is about 8 years behind Russia in military turbofans, but that gap is probably shrinking fast especially with Russian izd.30 pretty much stagnating with lack of funds and sanctions.

Izd. 30 problem is not lack of funds. The Russians have been having trouble manufacturing the engine reliably enough. I know last year they were trying to hire more welders but I have not heard of anything since.

I think it meant WJ-6E not 涡扇6E/WS-6E.

LOOL. Chinese engine tech have surpassed Russians. service life and MTBO exceed any Russian engine with a fair margin. Chinese also solved the chronic problem of black smoke, what Russians have been struggling ever since. Chinese precision manufacturing is miles ahead. not even a comparison. civil industry development have always an impact on your defense sector.

WS-10C performance in terms of thrust , inlet turbine temperature , fuel consumption and with digit control system is exceed all Russian engines. this is confirmed by deputy chief designer of J-20 during Zhuhai Air show 2021.

as gelgoog mentioned, The Russians have been having trouble manufacturing the engine reliably enough. coz their military industrial complex assembly lines still have soviet era elements. for example PD-14 their latest engine still Assemble on PS-90 assembly line.

I think that was a typo in the original article. It had to be. The correct term should have been 涡桨6E, not 涡扇6E. I chose to use 涡桨6 (WJ-6E) in my summary, but I forgot to point out the likely typo in the original article.

What's the engine in the last two images, looks like a GE F110

WS-10.. which variant ? no idea
