Method of manufacturing a wind turbine rotor blade

Abstract

The invention describes a method of manufacturing a wind turbine rotor blade (4), which method comprises at least the steps of providing a rotor blade mould (1) comprising a lower mould (11) and a segmented upper mould (12), the segmented upper mould (12) comprising a root end mould section (120) and a number of airfoil mould sections (121, 122); and arranging a composite material layup (2) in the lower mould (11). The inventive method comprises further steps of arranging the upper mould (12) over the composite layup (11) by: placing the root end mould section (120) at the position of an airfoil mould section (121); moving the root end mould section (120) in a longitudinal direction (Dz) to its intended position at the root end (20) of the composite layup (2); and placing the airfoil mould sections (121, 122) in their positions on the composite layup (2).
