Abstract
A rotor blade is provided, in particular for wind turbine generators including a means for the modification of the camber, wherein the modification of the camber is realized by means of elements passively coupled to one another, i.e. without external energy supply (apart from the energy contained in the airflow surrounding the rotor blade). One of the elements is therefore arranged at the leading and the trailing edge of the airfoil of the rotor blade, respectively. The coupling of the elements, the stiffness of the airfoil and the strength of the damping are hereby arranged in a manner suitable to be modified.
