Abstract

A wind-turbine rotor blade having an outer skin member formed of fiber-reinforced plastic, shear webs, and trailingedge sandwich members disposed closer to a trailing edge than the shear webs are, wherein the outer skin member at a dorsal side located closer to the trailing edge than a trailing-edge end of the trailing-edge sandwich member located at the dorsal side is or a vicinity of the trailing-edge end of the trailing-edge sandwich member located at the dorsal side is coupled, via a reinforcing member, with the outer skin member at a ventral side located closer to the trailing edge than a trailing-edge end of the trailing-edge sandwich member located at the ventral side is or a vicinity of the trailing-edge end of the trailing-edge sandwich member located at the ventral side.
