Wind turbines and wind turbine rotor blades with reduced radar cross sections |
| 摘要 |
Wind turbine rotor blades include a shell having a leading edge opposite a trailing edge, a structural support member that supports the shell and is disposed internal the wind turbine rotor blade between the leading edge and the trailing edge and extends for at least a portion of a rotor blade span length, and a resistive cellular support structure disposed at least partially about the wind turbine rotor blade that physically supports at least a portion of the wind turbine rotor blade and at least partially absorbs radar energy. |

1. A wind turbine rotor blade comprising:
a shell comprising a leading edge opposite a trailing edge; a structural support member that supports the shell and is disposed internal the wind turbine rotor blade between the leading edge and the trailing edge and extends for at least a portion of a rotor blade span length; and, a resistive cellular support structure disposed at least partially about the wind turbine rotor blade that physically supports at least a portion of the wind turbine rotor blade and at least partially absorbs radar energy, wherein the resistive cellular support structure comprises a plurality of open structural cells comprising a plurality of cell walls that form a plurality of cell passages, and wherein the structural support member at least partially comprises the resistive cellular support structure. |
