Abstract (en)
[origin: EP1939402A2] The rotor blade (1) comprises a support structure, which is made of fiber composite and has a metallic cladding structure (4) made of metal sheet. The rotor blade has a turbine blade (3), a blade root (11) and annulus filler (10), which is in a transition area between the turbine blade and the root. The cladding structure surrounds the turbine blade and below the annulus filler, it connects to the outer surface of the blade root flush with an edge or with an edge provided with recesses.
