Abstract (en)

[origin: EP2299124A1] The vane has a vane blade with a suction side wall, which is extended towards a vane blade tip by forming span width by an attached vane blade end. The blade comprises a profile (28) and a blade tip side profile (30) with a suction side contour (42) and a pressure side contour (40), and a partially curved skeleton line (32), and a linear chord (34) for vane blade height. The contours, the skeleton line and the chord are extended from a front edge point (24) to a rear edge point. The skeleton line of the blade tip side profile comprises two inflection points (36, 38).
