<p>A wind turbine rotor blade extension portion 30 comprises a permanent framework, having one or more chord-wise members 190, and a substantially span-wise member 200. A skin/membrane 220 is located over the framework to thereby generate a streamlined surface comprising first and second portions 120, 130 which are spaced apart at a proximal region of the extension and connected to one another at a distal region. The extension portion is configured to transmit aerodynamic loads from the skin/membrane, along the chord-wise members to a rotor blade 10 to which the extension portion may be connected in use by means of bonding, bolts, or a span-wise element on the extension portion slidably located in a recess on the blade.</p> |
