Abstract
A flying disk includes an outer ring, a plurality of blades spaced from one another and extending from the outer ring to a central hub to form a top plate thereof. The blades have a leading edge of greater cross-sectional thickness than the trailing edge thereof to provide lift. A bottom plate is attached to the top plate and defines a turbine structure including a series of slots and vanes extending downwardly from an edge of a slot from the bottom plate. The blades cause the disk to rise to a maximum altitude, and as the disk descends, the turbine structure regenerates the spinning motion thereby extending flight time.
