Chinese Engine Development

Isn't this only for land-based electricity power plants?

It is his speculation. But space permitting and navalized the compressor section with anti corrosion material. And adding chevron to air inlet to filter the water droplet. I don't see why it can't be converted to Naval propulsion. LM 2500, LM 6000 started out as commercial combined cycle turbine or peaker power plant GT. Later on it was navalized

Possible but the engine would require durability since the engine will be spun at various RPM at a moments notice unlike land based electric generators which basically rotates at regular RPM.

A GT plant is much smaller than a steam plant so space cannot be a problem. And providing power to EM cats wouldn't be a problem either.

and it's a goldmine.

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. This engine was mentioned earlier in this very thread.

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.

@jobjed - thanks for the updates, it's refreshing to see rational information on Chinese engine development for a spell.

Now guess who is irrational ? Well from the leak we know now that J10B is alive and doing well. I am glad that WS500 is successful I am the one that posted the article on WS500

Shaft material is hard to manufacture, even Japan has problem with it and have to licence technology from Sandvik and imported the machinery and tech assistance from Sweden. China don't have access to that kind of technology. She has to invent it herself!

He just confirmed what engine they'll be delivering. It's the non-afterburning Taishan, for UAVs. Good news for @Deino, he'll have another UAV to feast his eyes upon this year.

What's up, you heard the WS-20 had a shaft break so now it's refreshing rational information? LOL You wanna check the sources? Who's the author? What's his background? Looks like a Chinese forum that anyone can post on. Care if there's any evidence that the original author cited? Not this time? Everything sounds good? OK LOL

If it said WS-15 reached 180kN, ready to mount, you'd wanna see the author, author's IP address, social security number, home address, fingerprints, mailed blood/stool sample, author's military clearance, cited evidence, possible biases, and then if he made any spelling errors cus that would invalidate his trustworthiness and compromise the integrity of the whole article.
