METHOD FOR PRODUCING A TURBINE BLADE

摘要

The turbine blade (1) has internal cooling channels (12), each provided with a throttle device (11) for regulating the flow of the cooling gas. The latter is fed between the foot and head regions of each turbine blade, before the cooling gas is discharged via openings (8) in the surface of the blade, with the throttle device positioned at the rear end of the flow path, adjacent the discharge openings. The throttle device may be provided at the last deflection point (13) for the cooling gas flow direction before the discharge openings.
