Abstract
Among other things, the present disclosure relates to a wind turbine rotor blade that can be assembled at the site of its wind turbine. The blade includes an internal structure which may be pre-fabricated with connections to the shell skin prior to being transported to the site of its wind turbine. A filler material may be injected into the layers of fabric making up the shell skin at the wind turbine site and allowed to harden at approximately atmospheric conditions.
