Abstract

The segments of a segmented wind turbine rotor blade are screwed together at respective connection ends via a plurality of connecting bolts. Sleeve-shaped pressure pieces are arranged between the rotor blade segments, each of which is mounted on a connecting bolt. A plurality of first metal sheets is provided, each first metal sheet being arranged between a respective connection end and several pressure pieces, so that an electrically conductive connection is formed between several pressure pieces via a first metal sheet. The first metal sheets, which are associated with the first connection end, are each arranged along the circumference of the rotor blade offset from the first metal sheets, which are associated with the second connection end. Further, a metal sheet for a segmented wind turbine rotor blade is disclosed.
