Weirdest of curved blades

I’m pretty much looking for something that pulls air away, extending along (aligned with) base to which its attached, then that begins extending away from the base and pulls that air (towards the base) in like a vortex/conus- compresses- and then at the tip of the cone breaks away from the spiral to more or less begin pulling air down towards base but yet again more or less aligned with the base. So it’s 3 steps or evolutions that the blade makes and thus does 180/360* degree twirls as it changes tilt and vector. Any tips on tools that could let me do that.

Hi Zhan - we’ll need way more than your description, I think, to have any idea what this thing is…
