Okay, but how does it achieve lift? Anything motorized that hovers either needs rotors or jets. Surely the whole vehicle does not rotate, only some inner component.

Well, the one I saw that was designed back in the 60’s or so had a turbine engine in the middle, and a system to direct the exhaust out of a ring of ports arranged on the bottom of the disc. So, to change the direction of thrust, you only need to switch which ports you are allowing the exhaust to vent out of off. Probably a lot less moving parts in a system like that, too.
Oh, btw, I don’t know if they ever actually built that design with the turbine. I know they tried to build a few disc-type hovercraft back then, but they weren’t very successful.
