  • $\begingroup$ Welcome to Stack Exchange! Can you explain what you mean by "using centripetal force to hover or fly"? There's no obvious way that centripetal force could be used to make something hover or fly, so the question doesn't really make sense. $\endgroup$ – Terran Swett Jun 14 '19 at 2:34

There have been various proposals at various times to try to use things like centripetal/centrifugal force, impact vs. rebound, and various other methods to extract a net force from the movement of mass. All have failed, because momentum is conserved, and for the same reason, this method of propulsion will never work.
