METHOD AND APPARATUS FOR USE IN PROTECTING WIND TURBINE BLADES FROM LIGHTNING DAMAGE

摘要

A method and apparatus facilitate protecting wind turbine blades from lightning damage. A turbine blade for use with a wind turbine includes a first sidewall and a second sidewall. The second sidewall is coupled to the first sidewall along a leading edge and along an axially-spaced trailing edge such that a cavity is defined between the first and second sidewalls. A relief system is coupled to at least one of the first and second sidewalls. The relief system is configured to discharge flow from the cavity when a pressure within the cavity exceeds a predetermined threshold.
