Abstract (en)
The blade wheel of a turbine has at least one blade with its root (12) mounted on a disc, and at least one cooling passage is located between the wheel disc and blade root. A number of turbulators (26) is formed on at least one of the walls of the cooling passage and are designed in such a way that they increase the turbulence of a cooling fluid flowing through the cooling passage. The turbulators are formed on the underside (24) of the blade root platform (16). Independent claims are also included for the following: (A) a blade of a blade wheel of a turbine, especially a gas turbine, with turbulators on the underside of the blade root platform; and (B) a method for the manufacturing of a blade in which the turbulators can be formed in a working process forming the blade aerofoil.
