Turbine blade

摘要

The blade (10) has a platform (18) comprising a unit (18a) for partially defining a flow channel of a turbine and a separate unit (18b) formed on the former unit. The latter unit is arranged with the blade between a rotor and the former unit, where the blade is fastened to the rotor. A cooling channel (20) for cooling a coolant is arranged between the two units, where the coolant is guided within the turbine in an axial direction of the rotor and is extended along a curved line.
