<p>The blade (10) has a shovel blade (16) arranged transverse to a platform (14) and comprising pressure-side and suction-side shovel blade walls partially defining hollow chambers (24, 26, 28) that are arranged within the shovel blade. A unit (38) e.g. insert component such as separating wall (36), is arranged in the hollow chambers for changing a resonance frequency of the blade and/or changing rigidity of the shovel blade. Ribs (32, 34) extend from the suction-side blade wall to the pressure-side blade wall. Independent claims are also included for the following: (1) a method for producing a turbine blade (2) a casting core for a casting device for producing a turbine blade.</p> |
