Abstract

A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line. Each of the blade segments includes a pressure side shell member and a suction side shell member. A sealing tape is applied over the shell members so as to bridge across the chord-wise joint line. The sealing tape includes side edges that are aligned parallel with airflow over the shell members at the chord-wise joint line at a defined load and operational condition on the jointed wind turbine blade.
