Abstract

Arms extending radially outward from a hub (1) contain flexible elements (7) with a specific bending stiffness so that the blades (12,12') are inclined at predetermined angle during operation, at which centrifugal forces (CF) acting on the blades neutralize traction force (TF) acting on the blades.
