Vertical axis water/wind turbine motor using flight feather opening/closing wing system

A vertical axis drag type water-wind turbine comprising:

• a vertical axis that comprises rotationally symmetric arched arc wings around a rotational axis,
• a flier rotational axis at the boundaries of three or more divided segments of the arc connecting a center of a rotational axis of the vertical axis drag type water-wind turbine and a circumferential circle of the vertical axis drag type water-wind turbine and a support provided at two axial ends of the rotational axis and fixes both ends of the rotational axis, and
• fliers each having a longitudinal side attached to a flier rotational shaft, the flier rotational shaft defining along the flier rotational axis, the fliers freely rotate individually in a sector between two adjacent flier rotational shafts, forming a pair of wings with the flier and the flier rotational axis perpendicular to the arc connecting the center of the rotational axis of the vertical axis drag type water-wind turbine and the circumferential circle of the vertical axis drag type water-wind turbine on one side of the rotational axis, and when the wing against the fluid becomes convex, the fliers open, whereas, when the wing is concave while the wind turbine is being used, the fliers are lined up against the wind flow to close the space between the flier rotational shafts by wind flowing into the inner arc region of the arc connecting the center of the rotational axis of the vertical axis drag type water-wind turbine and the circumferential circle of the vertical axis drag type water-wind turbine before the wing becomes concave by receiving wind, and when the water turbine is used, synchronizing with the rotation of the wing, the fliers form a water receiving surface by gradually closing the space between the flier rotational shafts from the flier rotational shafts along the arc following the water flow, and obtaining rotational force from the water flow upon impacting the water-receiving surface and rotation around the rotational axis, and two or more pairs of wings are configured rotationally symmetric to achieve rotations of reduced rotational resistance by automatically opening and closing the fliers, where the supports have bended segments whose junction points of connecting divided segments are the supporting points, the folding direction is set to be the inner side of the arc connecting the center of the rotational axis of the vertical axis drag type water-wind turbine and the circumferential circle of the vertical axis drag type water-wind turbine in the horizontal direction of the support, along which the wing surface configured with the fliers, which are supported by the support, is folded to the inward side of the arc, where the folded line of the wing surface is approximately parallel to the rotational axis, the folding segment of the wing surface is two or more segments in the arc of the wing line shape, and the folding action loses the rotational force by losing the fluid-receiving purpose to avoid potential danger when a high-speed fluid appears by decreasing the projected area of the fluid for resistance reduction.
