ROTOR BLADE FOR WIND POWER FACILITY

Title:

ROTOR BLADE FOR WIND POWER FACILITY

Document Type and Number:

Japanese Patent JP2010043650

Kind Code:

A

Abstract:

To provide a rotor blade with a rotor blade profile and a wind power system that improve efficiency in comparison with the known rotor blade.

In the rotor blade for the wind power system, the position of maximum thickness of the rotor blade lies approximately between 15% and 40%, preferably between 23% and 28%, and the maximum profile thickness lies approximately between 20% and 45%, preferably between 32% and 36%. The rotor blade includes a two part configuration in a root area, a part of the rotor blade is configured in the outer side of a hub lining, a ratio between the profile depth of the rotor blade and the diameter of a rotor is approximately from 0.04 to 0.1, and a ratio between the profile depth of the rotor blade and the diameter of a spinner is between 0.5 and 1.
