Method for providing a curved cooling channel in a gas turbine component as well as coolable blade for a gas turbine component

摘要

Method for providing a curved cooling channel (20) into a gas turbine component, in particular into a blade (10), by means of an electrode (2), wherein an electrode (2) in the form of a helix is used, and the electrode (2) is driven so as to rotate around its central rotational axis (R); as well as coolable blade (10) for a gas turbine component with a helical cooling channel (20).
