Abstract (en)
The blade has a rod-shaped unit (37) that abuts above a chamber height to an interior (59) of end walls (27) to adjust flow of discharging coolant (33). The unit has section (45) with the shape of a segment of a circle, and forms an adjustable conduit with an interior (57) of end walls (25) to adjust the flow of the coolant. The unit is modifiable by rotation in a shortest distance between the section and the interior (57). Independent claims are also included for the following: (A) gas turbine (B) a method for manufacturing a casted turbine blade.
