Abstract
A sea-land-sky craft capable of navigating on the water, running on the land and flying in the air (that is, climbing vertically, flying horizontally and hovering in the air) usable in a new transportation system 1. The sea-land-sky craft comprises rotating wings rotatable in opposite directions on their centers. Mounting shafts are disposed at positions eccentric to the centers of the rotating wings and mount the rotating wings so that the orientation of the rotating wings can be turned. A cylindrical duct encloses the outer circumferences of the maximum diameters of the rotations of the rotating wings. A fuselage is located at a central portion of the craft. Movable struts are provided for connecting the cylindrical duct and the fuselage. In the sea-land-sky craft, the cylindrical duct is deformed into a fixed wing by the actions of the movable struts.
