The smallest 30 mm cartridge readily available for Chinese military aviation use is the old 30 x 155 mm used in the NR-30, that would be more compact than the more common 30 x 165 mm cartridge used in autocannon applications such as the Shipunov 2A42 in the Mi-28.

A part of me wonders if the video is AI generated from a still picture, but it is also possible that if the video is real and not AI generated, sometimes camera factors (shutter speeds etc) can make a rotor appear to do odd things.


In any case I wouldn't be too interested in this video/picture. It doesn't show us anything new and the video itself is a bit odd.

Not worth "promoting it" imo

The rotor turning is relative to the speed of filming, as in fps (frame per second). If you have watched some old war movies, you will notice the wheels of battle tanks turning backward while the tank was moving forward. Today's smartphones have frame speed of 30fps or 60 fps speed.

The rotor may appear to rotate clockwise or anti-clockwise will depend on the relativity between the video speed and the rotor speed.
