Abstract: A stability of a vertical axis combined water/wind turbine motor composed of a drag type and a lift type is improved by releasing convex surface resistance produced by a drag-type blade going against a fluid and increasing rotation torque by the reduction in resistance; during high-speed rotation equal to or higher than a fluid speed, all wing surfaces of the drag type are naturally brought into a released state as a result of being pulled by the lift-type blade rotation speed; and a danger at the time of increasing a fluid speed can be avoided by producing a fully-released state by rolling in feathers of a drag-type wind surface configuration, by decreasing the entire volume by folding wing surfaces to the rotation axis side, or by decreasing the entire structure by drawing feathers on the wing surface toward the rotation center.

Abstract: A wind/water turbine has a basic configuration in which both ends of blades which are in rotational symmetry are fixed to support plates, the blades have vanes, one of the vertical sides of the vanes is attached to a vane rotating shaft, and the free opposite sides each rotate freely in a sector extending as far as the adjacent vane rotating shafts on either side. The vanes are arranged such that when the blades of the wind/water turbine are convex, moving against the water flow/airflow, the vanes are pressed by the water flow/airflow and are opened, thereby reducing the rotational resistance, and when the blades have pivoted further and are concave, the spaces between the vane rotating shafts are closed, the water/air pressure is received over the entire surface of the blade, and thus a pivoting force that is increased corresponding to the reduction in rotation resistance is obtained.
