Beschreibung
Zusammenfassung:	The blade (1) comprises a blade body (6), a blade head (2), a pressure side wall (4), and a suction side wall (5), where the pressure side wall has a concave curvature at the blade head. The suction side wall is not curved in the direction of reference axis at the head. The blade head comprises a hollow portion. A curvature of the pressure side wall is formed in the hollow portion. The suction side wall is straight at the hollow portion. A transverse wall forms a bottom of the hollow portion, and is pierced by holes and dedusting holes. The blade body has a hollow cavity. The blade (1) comprises a blade body (6), a blade head (2), a pressure side wall (4), and a suction side wall (5), where the pressure side wall has a concave curvature at the blade head. The suction side wall is not curved in the direction of reference axis at the head. The blade head comprises a hollow portion. A curvature of the pressure side wall is formed in the hollow portion. The suction side wall is straight at the hollow portion. A transverse wall forms a bottom of the hollow portion, and is pierced by holes and dedusting holes. The blade body has a hollow cavity defined by the transverse wall and a part of the side walls. The side walls have constant thickness when moving along the reference axis of the blade. Independent claims are included for: (1) a core for producing a blade; and (2) a method for manufacturing a blade.
