Abstract: An aerial toy is disclosed that is adapted to be launched into the air using an elastomeric band. The toy includes a nose portion that is generally in the shape of an elongate ellipsoid that has a front end and a rear end. An elongate rib depends from the rear end of the nose portion in a direction generally along the long axis of the nose portion. This rib has a first end adjacent to the nose portion and a second end. The aerial toy also includes a pair of generally planar wing portions which are arranged so that the plane of the first wing portion is generally parallel to and spaced apart from the plane of the second wing portion. The first wing portion depends from the rear end of the nose portion and from the rib, and has a tapered outer edge. The second wing portion depends from the rib and has a surface area approximately 20-80% as large as the surface area of the first wing portion.

Abstract: An airfoil is disclosed that is adapted to be launched into the air using an elastomeric band. The device includes a nose portion that is generally in the shape of an elongate ellipsoid that has a front end and a rear end. An elongate rib depends from the rear end of the nose portion in a dkection generally along the long axis of the nose portion, and a pair of generally planar wings depend from the rib and from the rear of the nose portion. The plane of the first wing portion is generally parallel to and spaced apart from the plane of the second wing portion, and both wing portions have a tapered outer edge. The taper of the outer edge of the first wing portion is oppositely disposed to that of the second wing portion.
