That huitong posted it.

But again? What points towards the WS-15 might be ready when not even the engine looks like what that engine will look like?

It lacks a TVC and LOAN nozzle ... IMO it looks more like an EJ200 ...

And concerning Huitong, I have the deepest respect for him, but I don't take everything for granted without checking twice. And here I'm very much skeptical.

Hence my suspicion that it might be something in the class of Ws-13 or WS-19. It doesn’t look like a high thrust engine and contradicts what we know about WS-15.
Medium thrust engines tend to have a narrower profile. This engine looks like it’s got a wider diameter relative to its length. Still not ruling out the possibility that they just took a picture of an EJ200 and the aspect ratio of the image they used is slightly different than the pictures people have been using as a reference. Some key details look *very* specifically identical. Finally, the one image we do have of the WS-19 shows sawtooth nozzles, so I don’t think this engine is the WS-19.

huitong confirmed in person in the AAM thread that it isn’t the WS-15.

The core engine of the CJ-2000AX (C2XC-101) set ignition and reached full speed.

At the beginning of 2020, the development of the company's project, that is the Yangtze River 2000 Project (CJ denotes Changjiang or Yangtze River) has made a major breakthrough in the development of C2XC-101 engine core. On March 5, 2020, the engine ignition was done successfully. On March 10, the operating speed was 1.0, and on March 14, the air intake test performance was 1.0, with the maximum speed reaching 100.6%. In the whole test process, the performance of the core engine was stable without overtemperature vibration. And this completed the group responsibility target in 2020 ahead of the schedule.

The results of the first core engine of wide body airliner [COMAC C919], C2XC-101, is not only the first to verify the matching ability of each system of the core engine, but also an important platform to verify the key technology research results. The successful completion of the air intake state test marks that the performance of each component of the core engine and its matching meet the design expectation preliminarily, which lays a solid foundation for the subsequent high-altitude test of the core engine and the overall test…
