Abstract

A wind turbine rotor blade, comprising a first blade section, a second blade section and at least one pre-stressed tensioning element for connecting the first blade section and the second blade section with each other, wherein the rotor blade is split at an interface thereof in its longitudinal direction into the first blade section and the second blade section, wherein the first blade section is arranged closer to a root of the rotor blade than the second blade section, wherein a length of the at least one pre-stressed tensioning element is larger than half of a chord length of the rotor blade at the interface and wherein the at least one pre-stressed tensioning element extends deeper into the first blade section than into the second blade section. Due to the long pre-stressed tensioning element an everlasting pre-stressing of the interface of the rotor blade can be made. There is no need for later tightening of the prestresses tensioning element. As longer rotor blades can be produced and transported safely, reduced costs for the rotor blades can be expected. Lower cost of energy can be achieved.
