摘要:
An aerodynamically interactive artifact is proportioned to experience at least one of tumbling, fluttering, and autorotating motion when subjected to free fall in a gravitational field. Suitable shapes include films, strips, butterflies, birds, and the like. The artifact may be contain a neutraceutical, may be dissolvable in pet saliva, and may provide an olfactory sensation for a pet. Dimensionless parameters such as Froude number and length-to-thickness ratios may be used to select aerodynamically interactive motions.
