Jianzhong stated the contra-rotary compressor is the main innovation behind the system’s architecture. Because the high- and low-pressure rotors spin in opposite ways, the engine maintains relative speed and reduces absolute rotational speed, thus lowering centrifugal forces on blades and discs.

Well that’s interesting

centrifugal forces

For how long? Bet it isn't more than 15 minutes before pieces of metal come out.

I don't think it's made by Boeing

That's just a materials engineering problem at that point.

And does it really matter if your mach 6 hypersonic missile only has a 1500km range before its engine blows up? Still rather handy to have a few around.
