Spinning disk

  1. Mar 2, 2015 #1
    Can a spinning disk lift itself in the air?

    Can it, afterward, advance in a chosen direction?

    If yes, what is the correlation between the angular speed of rotation and the advancing speed?
    Does it need some "fins" to catch air, similar to the helicopter blades?

    Thank you very much.

    Not without some method of producing lift.

    I believe it would.
