Abstract
A method and apparatus to facilitate protecting wind turbine blades from lightning damage include a turbine blade for use with a wind turbine, wherein the turbine blade 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. A method for assembling the same is described.
