SEGMENTED ROTOR BLADE EXTENSION PORTION

摘要

A wind turbine rotor bladeextension portion is provided. The extension portion comprisesa plurality of segments, located adjacent one another in a span-wise sense. Aninterface between adjacent segments isconfigured to minimise disruption to fluid passing thereover and to inhibit transmission of longitudinal loads between segments. Each segment comprises a first surface and a second surface. The first surface isspaced from the second surface at a proximal region of the extensionportion and the first surface isconnected to the second surface at a distal region of the extensionportion to thereby generate a fair surface for a rotor blade to which the extensionportion is connected, in use.
