发明名称 Hand-throwable flying toy
摘要 A hand-throwable flying toy comprising a convex/concave surface with central aperture and peripheral flange-like rim that can be sailed through the air for use in short-range games of catch and short-range target games is disclosed. When thrown over short distances in a manner to produce both translational and rotational motion, the disclosed toy hovers at the apex of its flight path and then drops vertically downward without tendancy to bank left or right. In the preferred embodiment, means are provided to help stabilize the motion of the toy during descent: edge spoilers facilitate low-drag air flow past the outer edge of the toy; aperture spoilers facilitate low-drag air flow through a centrally-located circular aperture bounded by a circumscribed lip; lower spoilers placed in an annular region on the lower surface of the toy surround the aperture and facilitate the production of a surface-bound doughnut of turbulence that provides the toy with resistance against banking motion.
