Chinese Aero Engine information thread

[Deino]

To believe the WS-15 is already operational and delivering 24t of thrust is no longer a serious discussion.

 

[yusheng]

This should be considered as a disgusting reply on a serious discussion for ordinary members let alone a moderator, pathetic cheap shot indeed

its ok, i understand his position to suspect us and ask us to provide more information.
however, we are good at amusing them, then later astonishing them.

battle aircraft engine is top secret, even the codes or names of engine are not told in public, that why there are so many confusions among us.

i only gave a happy time. if you like i can translate more rumor making you laugh. maybe Deino will be "unhappy" since he wants serious discussion here.

我觉得18吨很牛了，24吨的话要多大函道比啊？

Guys, i have to agree. It's just rumors. I hope we don't jump and shout supapowa like our indic brethren. One thing for sure now is we know J-20 is using chinky engine, next find out the designation and capability of that engine.

What is sure that WS15 at least have 18 tons of max thrust.

@Beast man, why you say the engine with Al31FN nozzle on J10c is WS10?

We all know there are four J10b fit WS10x, the nozzle is silver and short same as the common WS10 engine. How you explain it, thanks.

I strongly belivd now J20 uses domestic engine no matter be it WS10b or WS15. I still skeptical when people claim the engine on J10c is not Russian's, we lacks enough proof.

Man per your logic, the current engine on FC31 V2 is a mini WS15 rather than some WS13E right?

And I also believe China can partially produce AL31F by reverse engineering.

when new one appears, the old new is going to retire.
if i say F110=CFM56=LM2500, you will not agree, but look at the picture below,

so, why not J31 too use WS15?

He he he... really don't think it's wise or serve any net positive value for China to disclose more its true power of the innermost segments (disadvantage is more certain), something so strategic like one of the ace cards in arsenal, the J-20. All the little, indirect divulgence is sufficient to just give some little hint. Just let it be in the "rumor status" for many more years to come! Let the unseen/unknown remain be unseen/unknown (what to show by naked oneself)... something like all the submarines, missile etc matters, just let the clearly visible stuffs like CV etc convey the very message. As about "faith" matter, it is not something to concern at all. In real situation, the "surprise" factor plays an advantageous position. Let the Pentagon and the Japanese resources guess and figure, analyze by themselves they need to work much harder to get the correct piece, if ever!

How good are we or how far are we from making world class aviation engines?

City banks on high-end manufacturing
Updated: 2016-06-10 08:35
By Wang Hongyi (China Daily Europe)


Faced with new challenges brought about by a slowing economy, Wuxi, Jiangsu province, is looking for new opportunities to boost the city's overall growth.

One major strategy is to develop its high-end manufacturing industry. Wuxi Turbine Blade, a State-owned enterprise founded in 1979, is one company leading the way with its development of engine turbines and aircraft parts.

Once a vital manufacturer of steam turbines in China, the company is currently a high-end engine parts supplier in the aviation and energy industries.

Since 2008, the company has produced engine turbine blades for aircraft. In 2011, its new blade production line entered the China market with output exceeding 1 billion yuan ($151 million).

"In recent years, Wuxi Turbine Blade adjusted its development strategy to become a bigger player in the aviation industry. We have gained a lot of experience in the production of new materials and research of new technologies," said the company's manager Gu Linhua.

In 2012, the company achieved a breakthrough in the production of aviation engine blades and the 35,500-metric-ton screw press, part of a 2 billion yuan large blades manufacturing and forgings project.

Two other key areas in its transformation have been increasing its global competitiveness and developing its overseas aviation businesses.

In 2015, its overseas business reached $70 million in revenue, accounting for 43 percent of total revenue. That is a growth of 6 percent from the previous year.
​

Energy contracts comprised $60 million of its overseas business, with $10 million for aviation contracts.

Rolls-Royce, a global manufacturer of aviation engine parts, signed a 10-year contract with Wuxi Turbine Blade in 2015. Other clients include L&T, PSM, GE and Siemens. The company has also expanded its business to the Middle East.

The company said it wants its overseas businesses to drum up 50 percent of total company revenue by 2017.

Hyatech is another example of Wuxi's private enterprises steering toward high-end manufacturing.

The company manufactures aircraft engine compressor blades as well as artificial joints for medical orthopedic instruments using in-house machinery and production lines.

Established in 2013, Hyatech's technologies and know-how are among the most advanced in the industry, the company claimed.

In 2015, the company's R&D and production project to produce blisks, a major rotor disk and blade for aircraft, went into operation, marking a turning point for the city as it looks to transform into a high-end manufacturing hub, said Hyatech.

A blisk can make the engine lighter by 20 to 30 percent, with efficiency improved by 5 to 10 percent.

Yan Qi, chairman of the company, said overseas countries have already used the company's blisk technologies in component structural designs of military and civil aircraft.

"In China, the blisk's technology, from design, manufacturing and testing, is still at an early stage," Yan said. "But with China's advances in civilian planes, jet engines and gas turbines, the Asia-Pacific region is becoming a new center for the global aircraft industry," Yan said.

Hyatech said it plans to invest 40 million yuan in the second phase of the blisk project and introduce a number of machines and facilities.

The company aims to produce 300 blisks with different specifications by 2019 and to become an R&D and production platform for the aircraft industry.

Highlights

Wuxi, Jiangsu province, aims to become a leader in intelligent manufacturing, the service sector and the green economy.

Smart manufacturing will be the main direction in the city's development of high-end manufacturing.

The city is promoting the development of manufacturing technologies, manufacturing processes and enterprise management.

The city is also exploring sustainable development and implementing a more environmentally safe manufacturing industry. It is encouraging energy intensive industries, such as the steel, chemical, textiles and building materials sectors to improve their equipment, advance technological processes, and establish online platforms to monitor energy consumption.

Emissions of major industrial pollutants will drop by 10 percent by 2020, it said.

Hyatech is making parts for those LEAP engine. FKKKKKK!!!
WuXi blade export parts to RR too....OMG. I knew they were selling turbine blades to BHEL, saw it on their inventory box in one documentary, didn't know they sell to Larsen & Toubro too. This is gonna piss off our Indy frens.

Bro, this HYATECH is private and watch the intro video, their production facilities looks awesome and the speech by their founder.

Guys, they are saying they are making CFM-56, LEAP, CF-34 compressor blades. Nobody knows about them because all info is in Chinese. This is crazy, how did I miss out this company. After seeing this, I am very sure we can make the best engines on earth. See the intro video.

Some Pakistani members said we are Alien when it comes to technical progress.

 

[Han Patriot]

Fake Pakistanis bro. Pakistanis will never say such things. They were some of the earliest to try out Chinese technology, I really hope CPEC can revitalize their economy and modernize them to be a rival to India, they have so much potential.

 

[yusheng]

i am afraid that i can not tell you because i don't know either.
but as Chinese characteristics, we will try any possible way to improve combat abilities, J10 is not exception.

 

[Tiqiu]

But then WS-15 would not be a single powerplant as the WS-10 or the EJ-200, M.88 or F119, but a "project" to develop certain propulsion technologies with the higher aim to develop a high-thrust powerplant for fighters and a miniaturized version for medium weight types, a high-bypass turbofans for civil airliner, this exotic combined-cycle hypersonic engine and maybe even a STOVL-version. But shouldn't this then have a project-designation similar to the Project 718 (aka J-20), Project 998 (for the KJ-2000) than a simple "WoShan" = Turbofan-number ??

Deino

Maybe there will be a unified code name from now on under the Aero Engine Corporation of China (AECC) which was formed last year. Before, there were more than 20 engine companies, many instituetes and aeroengine-repairing factories competing with each other for their own interest. As they were used to be answering to different authorities structually, to survive they had to compete to get aero engine projects and became less cooperative to each other. Perhaps that is why we see many engines all can be called/related to "WS-15" from different companies.

I chose to comment this time, because I constantly see members here acting in quite a hostile fashion towards people such as @Deino and @gambit

But is it OK to you for this "American" constantly calling "your internet chinese"?
