Claims20
A wind turbine blade, comprising:
- a flexible external skin and an internal support structure, together defining an aerodynamic profile of the wind turbine blade,
- wherein at least a portion of the internal support structure is adjustable to thereby vary said aerodynamic profile,
- wherein the internal support structure comprises a longitudinal structural support member and a plurality of transverse structural support members arranged along the length of the longitudinal structural support member, and
- wherein one or more of the transverse structural support members is formed of a first portion which is fixed and a second portion which is rotatably or hingedly mounted on the first portion, thereby providing the adjustability of the internal support structure.
