PRC high bypass engine, turboprop, turboshaft, and other aeroengines

to celebrate Xiaoman AECC published this unique poster with High Bypass Turbofan Engine on their Weibo account.

the interesting part is, 21 fan blades.. none of current High bypass Turbofan Engine has 21 blades. and of course this is just the poster but still it does carry some meaning so i have posted this.

GE90 has 22.

I wouldn't put too much stock into the diagram, for all we know it is a generative AI poster representing a generic engine.

AECC's self designed ATP-120A turboprop engine with 1230 kW power has completed ground testing performance metrics after 5 hours and 10 minutes of stable operation. This took just 4 months for the R&D team after ignition in -30C temp in January. It is expected to be able to operate in high altitutde airport and high temperature airport as well as other extreme environment.

keep in mind that being able to operate at high thrust in hot and high environment is a huge achievement for commercial engines, really adds to its versatility. It is normal for aeroengines to have performance penalties in such scenarios.
