Abstract: Wind turbine blade comprising a spar, a plurality of ribs rotatably mounted on said spar, and a rotating means adapted to rotate at least two consecutive ribs independently of each other. The blade can thus be operated so as to rotate at least two consecutive ribs independently of each other, although it is also possible to jointly rotate all the ribs.
