Chinese Aero Engine information thread

By the way if he means "Latest fighter jets to use domestically made engines by 2022" and connects this with the J-11B-production & WS-10C, I have daubs that then a WS-15 will be ready soon.

No. He's referring to the WS-15 IMO. But then again, Xu is the commentator who insisted that the J-20 used domestic engines as early as 2015 ... so not too accurate.

Latest fighter jets to use domestically made engines by 2022: experts

China's latest fighter jets will be powered by domestically made engines by 2022, experts said, as a television crew was given a glimpse of a J-11B fighter's radar system and engine.

"More Chinese fighting jets, including the J-10, J11, J-20 and J-31, will be powered by homegrown engines. China's new generation of military jets will all be powered by domestically-made engines within five years," Xu Guangyu, a senior adviser to the China Arms Control and Disarmament Association, told the Global Times.

The J-11B is powered by two domestic-made engines, a China Central Television (CCTV) reporter said, who gained access to a secret warehouse of the Shenyang Aircraft Corporation, a major fighter jet producer located in Northeast China's Shenyang Province. CCTV aired a report on the jet on Tuesday.

"The domestically made engine WS-10C on the J-11B is quite competitive to the previous Russian-made AL31 engine," Xu Yongling, an air force expert at the Chinese Society of Aeronautics and Astronautics (CSAA), told the Global Times.

Newly produced J-11B jets will be powered by the WS-10C, but engines on the current 120 J-11Bs won't be totally replaced due to the high cost, Xu Yongling said.

"China still lags behind in turbofan engines, especially engines that feature domestic single-crystal turbine blades made from metal rhenium," Xu Guangyu explained.

Most of the technology of single-crystal turbine blades is in the hands of State companies, Wang Yanan, chief editor of the Aerospace Knowledge magazine, previously told the Global Times. The Sichuan Province-based Chengdu Aerospace Superalloy Technology Company became China's first company to mass produce single-crystal turbine blades, CCTV had earlier reported.

The participation of private firms in the aviation industry would make production more efficient, Wang said.

Xu Youngling said the military aircraft engine industry is monopolized by State-owned companies, and will still take some time before more private companies enter this high-end industry.

"The domestic engines will be gradually tested on more fighters, Xu Guangyu stressed, adding that it would be strategically beneficial to the army since most fighter jets are powered by Western-made engines.

WS-10C is the successor to the WS-10B then. The J-20 is probably using the WS-10C then ... maybe that's the IPE or smt

Or that report at all if plain inaccurate at best !

This could refer to a production line restart ... which means that the new J-11Bs have uprated engines

Pupu-2012: "WS-10B is performing extremely well nowadays, much more than 13.2 tones thrust, the unstable and production struggle has long gone since a few years ago

Pupu-2012: "WS-10B is performing extremely well nowadays, much more than 13.2 tones thrust, the unstable and production struggle has long gone since a few years ago

Most likely 14 tonnes with the potential to be optimized to more than 15 tonnes.

Pupu-2012: "WS-10B is performing extremely well nowadays, much more than 13.2 tones thrust, the unstable and production struggle has long gone since a few years ago

Pupu suggests that the overall thrust is slightly lower than 14 tonnes in one of his posts ... so still way above 13.2

Most likely 14 tonnes with the potential to be optimized to more than 15 tonnes.

They could charge the engine up to 14.5 tonnes but that would compromise service life ...

I think over 15 tonnes with the improving lifespan.

Just look at the AL-31F for example, it started with 12 tonnes, but now it has become more mature with its maximum potential being exploited, and now it is over 13 tonnes with the improving lifespan.

I am not saying it is WS-10C, but what I am trying to say is do we really actually know what is happening in PLA? This is the most secretive and opaque military on earth. Therefore, there is no other way of having genuine information unless officially released through official media and CCTV programs as per globaltimes mentioned a WS-10C, could this C be the designation of the WS-10X? Who knows? I don't care as long as it's Chinese.

First, the WS-10 variants are not very "secretive" anymore. Numerous Big Shrimps have accurately forecasted the operational status of various Taihang engines (WS-10, WS-10B, WS-20 ...). The only engine we know very little about is the in-development WS-15, which the PLAAF is very secretive about. We all know the WS-10's thrust and life so there's nothing new to that. Regarding the WS-10C, they are probably referring to an uprated WS-10B or the "plus" variant that the new J-20 is testing. It probably is only a stop-gap measure until the WS-15 comes out 2 years later but until then, nothing much can be confirmed ...

From what do we know that ?? So far the this mystical WS-10C was never ever mentioned and only the WS-10B connected as the latest family member to the J-20A. Now with this IMO strange report suddenly a WS-10C is mentioned is expressis verbis connected with the J-11B ... so how do You come to the conclusion that this WS-10C is now the J-20's engine???

Deino

The WS-10C could be the WS-10B+ Huitong was referring to. Isn't the WS-10X an uprated WS-10B? It would make sense to give it a new letter designation ...

Even though it is hardly to image, but what you suggested is actually the reality. Except for some official report from sth like 《新闻联播》, usually pupu is much more reliable than CCTV or Chinamil.

If you are Chinese mil fan, you know what I mean.

I think that Pupu is one of the most reliable PLAAF insiders ...

 

[Deino]

Guys, I really don't understand it ... Is it that difficult to post all J-20 related engine speculations in the special thread? Why derail the J-20-thread and now the engines-thread with off-topic theories, giving moral support and speculations????

Therefore this thread is also closed ... and will be opened again when I'm back home and moved certain posts.

Come on ... It is not that difficult.

Deino in France.

Rolls Royce chairman predicts: Chinese-made jet engines coming soon

• Rolls Royce expects China to begin engine manufacturing for jumbo jets, company Chairman Ian Davis said at the Singapore Summit
• "It makes sense for industrialized countries to start doing so," he said

The world's second-largest economy will likely start manufacturing engines for jumbo jets soon, according to Rolls-Royce, a long-time engine manufacturer for commercial and defense aerospace.

"In the long-run, it's very possible and plausible that China and other countries will be looking to develop wide-body engines," said Rolls Royce Chairman Ian Davis at the Singapore Summit over the weekend. "It makes sense for industrialized countries to start doing so and we assume at some stage of the future that they will come in."


The Shanghai-based Commercial Aircraft Corporation of China, or COMAC, has already begun the development of a narrow-body engine.

The first C919 passenger jet made by the Commercial Aircraft Corporation of China (Comac) is pulled out next to a Chinese national flag during a news conference at the company's factory in Shanghai, Nov. 2, 2015.
"It's a big growth market and I think the key, as always, is to make sure you've got competitive products that really offer something to customers," said Davis.

In addition to aerospace and cars, Rolls Royce's other business segments include industrial products for the marine, nuclear and power sectors.

Davis said he continued to expect strong growth from the Middle East.

That market "is driven by aggressive strategies to attract traffic and ambitions to build a real hub in the region, not oil prices," he explained.

These are very very old images showing the WS-10 in its early day years ago. No TVC.
