Abstract
Official abstract text for this publication.
A blade ( 1 ) having a working shell ( 10 ) defining an inner space ( 16 ). The blade has a leading-edge space ( 31 ) and at least one filler means ( 40, 50 ) in said inner space ( 16 ) and a leading-edge fairing ( 20 ) protecting the working shell ( 10 ). The fairing ( 20 ) extends from a pressure-side part ( 21 ) to a suction-side part ( 22 ) via a central part ( 23 ). The working shell ( 10 ) has in the first zone ( 13 ): a pressure-side portion ( 131 ), a central portion ( 133 ), and a suction-side portion ( 132 ). The pressure-side portion ( 131 ) is secured to the pressure-side part ( 21 ). The suction-side portion ( 132 ) is secured to the suction-side part ( 22 ). The blade ( 10 ) includes first damper means ( 60 ) with damping material.
