ROTOR |
| 摘要 |
The stability of power generation efficiency against variation of fluid speed and direction can be improved. The disclosed rotor 1 for a wind or water power machine includes a hub 10, supported by a main shaft, and blades 20, each having a root end 21 connected to the hub. In a projection plane perpendicular to a rotational center axis O of the rotor, a leading edge 31 of the blade has leading edge bulge portions 36 and 37 protruding forward in the rotor rotational direction only at two different locations in the rotor radial direction. |

1. A rotor for a wind or water power machine, the rotor comprising a hub, supported by a main shaft, and a blade, having a root end connected to the hub, wherein,
in a projection plane perpendicular to a rotational center axis of the rotor, a leading edge of the blade has leading edge bulge portions only at two different locations in a rotor radial direction, the leading edge bulge portions each protrudes in a bulge shape forward in a rotor rotational direction. |
