Abstract

The invention concerns a segmented wind turbine rotor blade (110). The segments (132, 134) are screwed together at respective connection ends (136, 138) by means of a plurality of connecting bolts (146). Sleeve-shaped pressure pieces (144) are arranged between the rotor blade segments (132, 134), each of which is mounted on a connecting bolt (146). A plurality of first metal sheets (150) is provided, each first metal sheet (150) being arranged between a respective connection end (136, 138) and several pressure pieces (144), so that an electrically conductive connection is formed between several pressure pieces (144) by means of a first metal sheet (150). The first metal sheets (150), which are associated with the first connection end (136), are each arranged along the circumference (151) of the rotor blade (110) offset from the first metal sheets (150), which are associated with the second connection end (138).The invention also concerns a metal sheet (178).
