Abstract (en)
[origin: EP1921269A1] The blade (10) has a set of fins (18) arranged in a cooling channel (14) in a sequence of one following the other. The cooling channel extends along a length of a flow-inlet edge (12), where a pair of fins is formed with the respective ribs. The fins are arranged in a shape of ice-skating-step. The fins are formed with front and rear walls (16, 20) in single-piece, and the cooling channel extends parallel to the flow-inlet edge.
