Are oriented in the same direction in parallel when used as a sail
When the wing is used as a sail, fixing means for fixing the vertical axis to the hull are provided, and the fixing means is released to use the vertical axis and the wing as a windmill. In this case, a driven machine is provided for operating by the rotational force of the wind turbine, and the lower part of each of the plurality of blades is
Rotation adjustment for switching the use state of each wing on the moving center axis
A joint drive motor is provided.

[0006]

In the above-mentioned wind-powered ship according to the present invention, a plurality of wings are rotatably adjusted in a direction to generate a thrust by receiving wind force during sailing, and the vertical axis supporting the wings via a support frame is provided. The wings function as sails for propulsion by being fixed to the hull by the fixing means. On the other hand,
The plurality of blades are rotated and adjusted in a direction that can rotate the vertical shaft in response to the wind force, and the fixing means of the vertical shaft is released, so that the vertical shaft and the blades rotate as a windmill. Thus, a driven machine such as a generator connected to the vertical shaft is rotationally driven.
