Reduction of radar cross-section of a wind turbine

摘要

The various technologies presented herein relate to formation of a wind turbine blade having a reduced radar signature in comparison with a turbine blade fabricated using conventional techniques. Various techniques and materials are presented to facilitate reduction in radar signature of a wind turbine blade, where such techniques and materials are amenable for incorporation into existing manufacturing techniques without degradation in mechanical or physical performance of the blade or major alteration of the blade profile.

主权项

1. A method for reducing a radar cross-section (RCS) of a wind turbine blade, comprising:
fabricating the wind turbine blade to comprise a core layer and a skin layer; and incorporating between the core layer and the skin layer a fabric structure, wherein the fabric structure comprises a woven layer and a conductive layer formed on a surface of the woven layer, and wherein inclusion of the conductive layer in the wind turbine blade causes the RCS of the wind turbine blade to be reduced by at least 20 dB in comparison with a wind turbine blade not including the conductive layer.
