Aerodynamic sound-emitting amusement device

摘要

An amusement device toy in the shape of a flying saucer disk having aero-dynamically shaped whistle structures for emitting different tones when the disk is thrown into the air, mounted symmetrically on the periphery of the disk. The size of the whistle air chambers may be varied or the openings for admitting air displaced at different angles to obtain the different tones, while the aero-dynamic shape of the whistle assures laminar flow of air over the whistle entry for increased air flow.
