From Hendrik_2000/SDF:
Well, I guess the rumor of Huangshan 黄山 is true after all. With the maturing of Gas Turbine industry in China, I am not surprise finally they get it all right. Years of frustration and disappointment is not in vain. And what is the intended user of this engine, FC-31? Any one knows the specs of this engine?
The Global Security has this article (2018.10.12) probably a translation of the old rumor.
At the 2018 Zhuhai Airshow, the big vector engine is not only the one that is equipped on the J-10B, but is also a quietly lying on the stand, proclaiming China's second stealth fighter, J-31, will soon have a domestic turbofan engine; this engine is the Turbofan-19 Huangshan, the medium thrust engine that had only appeared in rumors in the past two years. For a double-engine medium-sized fighter, the thrust and fuel consumption of the large thrust engine are too large, wasteful of money, and poor cost-effectiveness; the most efficient method is to install two medium-thrust engines, and the WS-19 is such an engine. China Aviation Industry Corporation (AVIC) had previously disclosed a vector engine with a maximum thrust of 9800Kgf. This engine is considered by the outside world to be the WS-19 涡扇-19 ('Wo Shan' means Turbofan) with codename "Huangshan" 黄山 engine, matched with FC-31. This project has produced and successfully completed the development of QC185, QC400, GT25000G military ship-borne turbine shaft blades, WS-18, WS-19 turbofan engine shaft blade development, 624 AT project drones and other models to attack the mission. In mid-2017, Aviation Industry Corporation of China (AVIC) first published an engine model called "Turbofan-19" (WS-19) for a summary of the results of the "Shaft-type blade universal combination tester". Some military observers revealed on the Internet that "TurboFan-19" is a long-rumored new Chinese engine. It is similar to the name of "Taihangshan" 太行山 and "Emeishan" 峨嵋山, and the name of "TurboFan-19" has codename "Huangshan" 黄山. The target of the Turbofan-19 is the General Electric F414 turbofan engine, which is larger than the European EJ200 engine in terms of maximum thrust.
Before the Turbofan-19 model was confirmed, the detailed report on China's new medium-thrust turbofan engine was only the "S3-2 type technical verification machine" project. The S3-2 type technical verification machine was a double rotor and afterburner. The turbofan engine with vector nozzle has a maximum state thrust of 9800kgf, and the thrust-to-weight ratio is 9th [!? -- I suspect there's a notation mistake here but I don't know the correct one so I just let it as is]. The goal is to obtain the national project after the verification technology is up to standard, and become an important member of the domestic engine type spectrum. Aeroengine market demands for medium-thrust turbofan engines with vector nozzles.
From the performance parameters of the S3-2 type technical verification machine and the performance description of the Turbofan-19 "Huangshan" on the internet, the two are very close. It is possible that the advanced technology development of the S3-2 type technical verification machine has reached the target. After obtaining the approval of the engine model development project, it entered the prototype development stage.
At some airshows in China a few years ago, there was an unidentified medium-thrust engine more than once. The maximum afterburning thrust was 9500kgf. In terms of appearance, this engine not only has a structure similar to the Russian RD93, there are also similarities with the American F404 and European EJ200 engines. However, this engine even though appeared in the airshow, there is no follow-up related information to prove that it uses the official model and name.

From Watdahek/SDF:
The main reason we know this should be WS-19 and probably not WS-10 variant or WS-15 is because of the article saying the team is from 中国航发涡轮院 also known as the INSTITUTE 624 located in Chengdu [Chengfa Turbine Institute !?].
Both WS-10 and WS-15 engines are projects undertaken by INSTITUTE 606 in Shenyang.
Some also recognized the head of the project as Huang Weina, who is supposedly the head of a “medium-thrust engine” development team, but I have conflicting sources on that.

Top new turbofan engine to power China's carrier-based stealth fighters: military specialist
By Liu Xuanzun Source:Global Times Published: 2019/4/17 18:09:37

The young members of a team of Chinese aero engine designers will be given an award for successfully designing and prototype testing of a new top-class turbofan engine that will help Chinese fighter jets take on their advanced foreign counterparts, as Chinese experts said on Wednesday the new engine is likely to be installed on China's new carrier-based stealth fighter jets.
With 124 members who are 35 years old or younger, the 193-person development team at the Gas Turbine Research Institute under the state-owned Aero Engine Corporation of China (AECC) will receive a provincial award during China's Youth Day on May 4, according to a statement released by the government of Chengdu, capital of Southwest China's Sichuan Province, on its WeChat account on Monday.
Without giving the designation of the engine, the statement said it is a piece of military equipment that will rival advanced foreign fighter jets and represents China's highest technical level in aero engines. It is one of several major aero engine projects of the country, the statement said.
It took the development team only a year to design the engine, and just six months to finish testing the first prototype, and the manufacturing cycle has been reduced by two thirds, the statement said.
With the new engine, China's future advanced fighter jets will finally solve the "heart problem," Wei Dongxu, a Beijing-based military analyst, told the Global Times on Wednesday. "This is great, great news," he said. The aero engine is often dubbed "heart of aircraft" as it provides the power the aircraft needs.
Military observers said China has made astounding progress in the development of advanced military aircraft, highlighted by the J-20 stealth fighter jet. The industry, however, has been hampered by domestically made engines that previously had sub-optimal thrust and life span.
Advanced turbofan engines are difficult to develop, especially the manufacturing of fan blades, which must be built to resist very high temperatures and pressure, Wei noted.
The upcoming award is an indication that China has made breakthroughs not only in designing, but also manufacturing, Wei said.
Despite the fast pace of development, Wei said the new engine still needs a considerable amount of testing under different situations, before it is confirmed reliable and enters mass production.
This turbofan engine is likely to be used on China's stealth fighter jets in the future, Weihutang, a column affiliated with China Central Television (CCTV), reported on Tuesday.
Wei said the engine could be related to China's medium-sized twin-engine stealth aircraft FC-31, which could become China's next generation aircraft carrier-based fighter jet.

But maybe i wasn't up-to-date and this institute is just a former-AVIC as AECC was split from them.
I was sure it was AVIC's institute who developed it :0Top new turbofan engine to power China's carrier-based stealth fighters: military specialist

Yeah and that is even when AVIC is still in control of several engine institutes.
I bet by moving to AECC they had to abandon their name '624'

OedoSoldier on 18 April:
“It is said that WS-15 engine has been loaded on the test aircraft.
In addition, the type of test aircraft is not clear (not J-20)”
Furthermore, later OedoSoldier even provided the info source of this development:

I believe you have seen this picture of the turbofan engine development team of AVIC Turbine Research Institute standing in front of the Gaussian blurred photo of the new medium-thrust verifier. According to the basic description, this should be the new medium-thrust turbofan engine called WS-19 (Turbofan-19). In that case, the author feels that this medium-thrust series can be written down a little more.

Could very well be. The size definitely looks right. I think the WS-15 guys might have gotten a little jealous of the coverage the WS-19 got and decided to post this picture.
Can any of the personnel be identified like Huang Weina was in the WS-19 picture? That badge should be readable with image enhancement software.
Edit: the source article for the image - http://www.aecc.cn/xwzx/jqyw/390088.shtml. It says the article was released on the 15th of April (coincidence?), around the same time as the WS-19 picture. It might have been a coordinated release.
The official in the windbreaker is Cao Jianguo, the chairman of AECC, and the image was taken at a test flight centre.

Thanks for the translation, but ... Huhuuuuuu ... Indeed, it's just a WS-10 Taihang.

The headline of the article I posted makes clear the chairman of AECC is visiting maintenance and field service personnel. I should have picked up on that from the beginning.
