Wind turbines and wind turbine rotor blades with reduced radar cross sections

摘要

Wind turbine rotor blades (16) include a shell (40) having a leading edge (28) opposite a trailing edge (30), a structural support member (50) that supports the shell (40) and is disposed internal the wind turbine rotor blade (16) between the leading edge (28) and the trailing edge (30) and extends for at least a portion of a rotor blade span length (32), and a resistive cellular support structure (80) disposed at least partially about the wind turbine rotor blade (16) that physically supports at least a portion of the wind turbine rotor blade (16) and at least partially absorbs radar energy.
