Abstract
A wind-turbine rotor blade has an outer skin member formed of fiber-reinforced plastic, shear webs, and trailing-edge sandwich members disposed closer to a trailing edge than the shear webs are. The outer skin member at the dorsal side located closer to the trailing edge than a trailing-edge end of the trailing-edge sandwich member located at the dorsal side 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 the ventral side located closer to the trailing edge than the trailing-edge end of the trailing-edge sandwich member located at the ventral side or a vicinity of the trailing-edge end of the trailing-edge sandwich member located at the ventral side.
