Abstract (en)
The present invention relates to a turbine assembly (10) comprising at least one basically hollow aerofoil (12) with at least one trailing edge (14) comprising at least two wall segments (16, 18) that each comprises an inner surface (20, 22), wherein the inner surfaces (20, 22) face each other, and wherein the inner surfaces (20, 22) enclose at least one exit aperture (24) extending basically in span wise direction (26) of the at least one basically hollow aerofoil (12). In order to provide a sufficient heat transfer and thus cooling of the turbine assembly (10), it is proposed that at least one of the inner surfaces (20, 22) of the at least two wall segments (16, 18) of the trailing edge (14) comprises at least one surface increasing structure (28, 28') extending partially into the at least one exit aperture (24) from one inner surface (20, 22) to the other inner surface (20, 22).
