Rotor blade with a segmented supporting structure and method for manufacturing the rotor blade

摘要

A rotor blade (10) with a supporting structure, wherein the rotor blade (10) comprises a rotor blade base section (11) and a rotor blade tip section (12). The rotor blade (10) comprises furthermore a rotor blade longitudinal direction (13), wherein the rotor blade longitudinal direction (13) extends from the rotor blade base section (11) to the rotor blade tip section (12). The supporting structure comprises a first supporting segment (20) for supporting the rotor blade base section (11) and at least a second supporting segment (30) for supporting the rotor blade tip section (12). Furthermore, the supporting structure comprises the first supporting segment (20) and the second supporting segment (30) along the rotor blade longitudinal direction (13). The first supporting segment (20) is joined to the second supporting segment (30) in a supporting structure transition section (40), wherein the supporting structure transition section (40) is located in between the rotor blade base section (11) and the rotor blade tip section (12). Finally, the first supporting segment (20) and/or the second supporting segment (30) comprises a fibre material. The blade is well suited for a wind turbine engine, particularly for a rotor blade (10) of a wind turbine engine, specifically a rotor blade which comprises a curved, i.e. swept shape.
