Chinese Aero Engine information thread

http://www.janes.com/article/67235/china-and-russia-to-collaborate-on-aero-engine-r-d

State-owned enterprises in China and Russia have agreed to collaborate on aero-engine technologies, China's State Administration for Science, Technology, and Industry for National Defense (SASTIND) has announced.

The memorandum of understanding (MOU) was signed in mid-January by the China Aviation Research Institute (CAI) - a subsidiary of the Aviation Industry Corporation of China (AVIC) - and Russia's Central Institute of Aviation Motors (CIAM), SASTIND said in a press release published on 24 January.

According to SASTIND, the MOU will support a "long-term co-operative partnership between the two institutions". It added that the agreement would support potential collaboration in a range of aero-engine activities, including simulation technologies, distributed control systems, engine health management, thermal management, and fluid control.
 
Not sure how reliable this discussion is, but there seem to be some interesting news (via'jobjed'/SDF):

http://lt.cjdby.net/thread-2365666-1-1.html

1. The chief designer of the Taishan has transferred from Guizhou Liyang to the Chinese Academy of Sciences, Institute of Engineering Thermophysics. Apparently he left just when Liyang was about to assign him to an expert group.

2. WS-15 development is encountering difficulties. It is currently in "stage C" which is the stage where preparations are made to mount the engine onto a ground-based testbed.

3. WS-20 probably won't be mounted on Y-20 this year.

4. In 2016, the WS-20's shaft broke during testing. This means QA is being revamped before WS-20 can proceed further. The latest picture that showed the WS-20 de-mounted from the Il-76 testbed aircraft is due to the need to replace and investigate the damaged WS-20.

5. The next-gen medium-thrust engine project is about to be commissioned with the goal of beginning its use around 2022.

6. The aforementioned Institute of Engineering Thermophysics apparently designed a very nice low-thrust engine that put AVIC to shame.

7. The WS-10B did not compromise lifespan in exchange for increased thrust.

8. The progress on the WS-10B is pretty good. Progress on WS-10IPE is unclear.

9. 624th Institute, based in Chengdu, successfully developed the WS-500 and its close sibling, the WP-200. They are now trying very hard to prove themselves so they can be assigned more important projects.

10. The WS-500 was recently mounted on a UAV which was launched via EMALS. That is news to me! When did a UAV equipped with a small turbofan get launched using EMALS?

11. Guizhou Liyang, where the insider works, will deliver 3rd-gen turbofan to the PLAAF and PLANAF this year; currently unclear as to which engines those will be. Engine generations in China are identical to fighter aircraft generation. So WS-10 and J-11B are 3rd-gen products.

Besides discrete points, the poster also expressed his perspective on interactions between various institutes and plants. He does not think very optimistically of Liyang's prospects as AVIC has apparently been giving them unrealistic goals and being all-round disruptive to Taishan's development.

SAC also took a comprehensively-tested engine core design along with supplementary material from 624th as the basis for WS-15. This means that 624th basically did most of the design work for the WS-15 and 606th is responsible for bringing the design to fruition.

And "minshan" is dropped too ?

China is a gold mine for Motor Sich. Btw wonder what WS 200 and 500 are all about. Are thise UAV engines only ....
 
Stealth fighter soon powered by local engines
By ZHAO LEI | China Daily | Updated: 2017-03-13 03:51

A domestically developed engine will soon power the nation's latest stealth fighter jet, according to a senior scientist working for Aero Engine Corp of China.

"It will not take a long time for our fifth-generation combat plane to have China-made engines," said Chen Xiangbao, vice-president of the AECC Beijing Institute of Aeronautical Materials. Chen, also a member of the Chinese Academy of Engineering, was referring to the J-20 stealth fighter.

"The engine's development is proceeding well. We also have begun to design a next-generation aviation engine with a thrust-to-weight ratio that is much higher than that of current types," he said. Thrust-to-weight ratio is considered the top indicator of an aviation engine's capability.

Chen, who is a member of the Chinese People's Political Consultative Conference National Committee, spoke to China Daily on the sidelines of the political advisory body's annual session.

The People's Liberation Army Air Force recently confirmed, without elaborating, that the J-20 has been put into active service. Aviation industry observers said the plane is still equipped with Russian-made engines due to the lack of a suitable domestically developed engine.

Chen said Chinese scientists and engineers are striving to catch up to the world's top players in terms of research and development into cutting-edge aviation engines, but the country still has a long way to go before it can develop and produce world-class engines, Chen said.

"For instance, we are able to develop the two most important components in an advanced engine — the single crystal superalloy turbine blades and powder metallurgy superalloy turbine disks — but in mass production, the products' quality is not very satisfactory," he said. It is a matter of time and persistence to make reliable engines, he said.

"The road to success is filled with setbacks and failures. Each of the world's engine powers has walked this road," Chen added.

Yin Zeyong, head of AECC's science and technology commission, previously said that a good engine is the result of not only good design but also time-consuming experiments and tests.

Despite China's tremendous achievements in science, technology and manufacturing industries over the past several decades, aircraft engine-making remains one of the few fields in which the country still lags behind top players like the United States and Russia. Because of the sophistication of advanced aircraft engines, such as the afterburning turbofan engine, which drives the US Lockheed Martin F-22 and Russia's Sukhoi Su-35, only the five permanent members of the United Nations Security Council have the technical wherewithal to develop and produce them.

Tang Changhong, chief designer of China's Y-20 strategic transport plane and a member of the CPPCC National Committee, told West China City Daily that the Y-20 will be equipped with indigenously developed engines around 2018 or 2019.

WS-20 Engine for Xian Y-20 Strategic Airlifter in the next year?
Love this part :smitten:

Congrats to our Chinese brothers :china:

REALLY? Only five countries? No Germany? No Japan? Or any other?

Germany has the capabilities. But what's the point? The application will be so little it won't be economical to develop one alone. That's why The EU jointly developed the EJ 200 for the Eurofighter Typhoon.

Japan has the capabilities, but not for an high thrust one. There 5 th generation tech demonstrator 'Shinshin' has Japanese made enginess AFAIK.

I think Chinese media was referring to thrust >100kn. Only China, US and Russia can produce it. The problem with WS-10A was never about thrust and thrust:weight, it was about production quality and reliability. I heard newer engines are around 2000-3000 hrs, half of the 5000-6000 hrs lifespan of US engines.
 
WS-15 before maiden flight???:coffee::D:enjoy:

The newest one has increased lifespan to 3500-4000 hours.
