PURPOSE: A rotor blade for a wind turbine, and combination of the wind turbine with a radar station are provided to reduce the entire radar reflection from the rotor blade by maintaining permeability to the energy of incident radar. CONSTITUTION: A rotor blade(10) for a wind turbine comprises a casing structure. The casing structure is made of flat fiber composite materials for forming a surface(20) of the rotor blade. The fiber composite materials have a reflection minimum in 1~10 GHz range of frequency on a leading edge(16) and trailing edge(18) of the rotor blade. A frequency-dependent radar reflectivity with respect to radiation of the radar vertically incident to the surface is offered. |
