摘要

The rotor sail has a surface with a bulged profile, where the final shape of the sail corresponds to a row of tori, which are stacked on top of each other, or a row of vehicle tire tubes, which are stacked on top of each other. The number and height of the tori are optimized by a wind-channel test, where the sail is made of steel or non-ferrous metal, glass reinforced plastic, carbon-fiber reinforced plastic and film or fiber made of plastic.
