The walls enclose a central cavity (-) for the passage of cooling air, the cavity being partitioned into a leading edge- and a trailing edge region () by at least one longitudinally extending first web () connecting the suction side wall with the pressure side wall and a second longitudinally extending web (), connecting the first web with the suction side wall, thereby defining a first and second entry chamber (). The first web () is provided with at least one cross-over hole (H) between the first entry chamber and the leading edge chamber (), whereas the second web has no openings.
