<p>The cooled turbine rotor blade (10) has a load bearing vane profile (16) with a front edge (18) and a rear edge (20), with cooling channels (22) which are separated partly from each other by a rib (24a,24b,24c). One of the ribs merges in the area of a pinion (27) curved in the closing wall. An opening (40) is provided for connecting one of the two adjacent cooling channel (22c,22d) arranged in a curvature (32), by which a part of a coolant flow (29) is flowed for impact cooling of the closing wall.</p> |
