A method of manufacturing a vane (61), the vane (61) comprising a root part (62), an aerofoil (74) and a cooling channel (63) extending through at least the root part (62), the cooling channel (63) is defined by a wall (76) and comprises a flow adaption feature (64), the method comprises the steps of forming the vane (61) with the flow adaption feature (64) defining an inlet opening (73) having an initial and nominal flow area Ai and which is less than a flow area for first desired coolant mass flow, testing the mass flow rate of coolant passing through the cooling channel (63) to find an actual mass flow, determining an increase in area of the flow adaption feature (64) to achieve the desired coolant mass flow based on the actual mass flow, machining the flow adaption feature (64) to increase the inlet opening (73) area to achieve the desired mass flow. A corresponding turbine vane is also provided. |
