Abstract (en)
[origin: EP1621730A1] A cooling channel (41) is provided in the outer wall of the blade that is impinged upon by a working medium (A). A cooling fluid (KF) flows along the longitudinal axis of the cooling channel. A device is provided in the cooling channel for imparting a swirl on the flowing cooling fluid. Preferably, at least one turbulator element (47) is provided on the inner surface of the cooling channel. Independent claims are included for a gas turbine and for a method of casting a cooled component.
