Turbine blade for a turbine with a cooling channel

摘要

The blade has a platform (16) for defining a flow channel in a turbine, where the platform has a coolant channel (20), which extends in the platform and guides the coolant. The coolant channel leads to two connection openings of the platform. An auxiliary component (24,26) is fastened at the platform, and has a connecting channel (28), which connects the openings with each other in a fluid-conductive manner. The platform extends transverse to a longitudinal extension of the blade along a main defining surface (30), and has front surfaces, which are arranged transverse to the extension.
