Keep in mind when Pupu first talked about the J-20’s WS-10s he suggested they were 13.2 tonne engines. More recently he’s suggested they’re 14.5 tonne engines. This tells me Pupu’s own information isn’t always up to date, which is something he himself has attested to before...
Chinese Engine Development

- Start date
The guy is Song Xinshi and he was apparently a fighter pilot (and therefore is appraised to be reliable by some in the cjbd forum (?) ).
" WS-19 thrust ratio exceeds 10, and its thrust exceeds 10 tons, instead of the 9,500 kilograms previously transmitted online."
"The channel ratio of turbofan 19 transmitted on the Internet may be wrong and not so large"
All this from a Chinese tube video btw.

Why are we buying a lpt shaft from Norway? has COMAC been living under a rock?
Its equipment for engine test and development. Its not for use in the engine itself. Understand that china is behing in aircraft engine tech and must get whatever it can get from nations with more advanced tech, more so for an engine for civilian use.

China’s variable-cycle engine has carried out flight tests: After more than ten years, Nanjing University of Aeronautics and Astronautics, Shenyang Institute of Aviation Industry, Northwestern Polytechnical University jointly completed the "Research and Application of Key Technologies for Multidisciplinary Simulation of Advanced Combat Aircraft Propulsion Systems".
The project was patented 16 Among them, 14 invention patents, 2 software copyrights, 2 monographs, 13 SCI papers, 12 EI papers, 1 third prize of the 2017 China Machinery Industry Science and Technology Progress Award, and 2 national military standards , The relevant results have been applied in multiple domestic aero engine models, the first carrier-based fighter, the first ground-attack unmanned combat platform, the first domestic modal conversion flight test and other models, and the flight verification has been completed, which can support The research team was appointed as the stability support team for the development of a certain key aero engine model of the country for the demonstration and development of the next generation of multi-purpose advanced fighter jets and high-altitude long-endurance unmanned reconnaissance aircraft. The research results have important military and social benefits.
