A rotor for a wind/water power machine that can reduce fluid resistance. A rotor provided with a hub and blades. A projected plane perpendicular to a rotational center axis line of the rotor, front edges of the blades protrude, in at least one part, forward in the rotational direction of the rotor relative to a first line segment; front edge protruding tips thereof are disposed in positions separated outward in the radial direction of the rotor from the outer peripheral edge of the hub by a length 0.4 to 0.6 times the length of the blade; and portions of...
1. A rotor for a wind or water power machine, the rotor comprising a hub, supported by a main shaft, and a blade, a root end of the blade being connected to the hub, wherein in a projection plane perpendicular to a central axis of rotation of the rotor, an entirety of a leading edge of the blade protrudes forward in a rotational direction of the rotor with respect to a first line segment connecting an inward end of the leading edge in a radial direction of the rotor and an outward end of the leading edge in the radial direction of the rotor,an entirety o...
