Abstract:
A turbine blade for a gas turbine, has a blade, with a blade wall and a crown base arranged at the free end of the blade. The blade wall surrounds at least a first and a second flow chamber, between which a first separating wall is arranged, wherein a free through-hole for connecting the first and the second flow chambers is present between the first separating wall and the crown base. Furthermore, at least one cooling air opening is present in the crown base. The cooling air opening is designed as a relief groove, which extends to a point over the through-hole at least in some sections.

Claim (Index 1):
A turbine blade for a gas turbine, comprising:\n a blade root, and an aerodynamically curved blade airfoil, which has a blade wall and has a crown base which is arranged at the free end of the blade airfoil, wherein the blade wall comprises a pressure-side and a suction-side wall section and encloses at least one first and one second flow chamber, between which a first separating wall, which connects the wall sections, is arranged, wherein the first separating wall has, at the end pointing toward the crown base, a through-passage for connecting the first flow chamber to the second flow chamber, and wherein at least one cooling-air opening is present in the crown base, wherein the cooling-air opening being formed as a single relief groove ( 21 , 23 ), or being formed by at least two relief grooves ( 22 a , 22 b , 22 c ) which are arranged next to one another in an offset manner, the individual or combined minimum length (L) of which relief grooves ( 21 , 22 a , 22 b , 22 c , 23 ) corresponds to at least 0.5 times the width (B) of the first separating wall and which relief grooves ( 21 , 22 a , 22 b , 22 c , 23 ), on both sides, extends/extend individually or in combination to beyond the through-passage, wherein a second separating wall is arranged adjacent to the second flow chamber and a third flow chamber is arranged opposite the first flow chamber, and wherein a second through-passage is present between the second separating wall and the crown base, which has at least 2 times, in particular at least 5 times or in particular at least 10 times, the free cross section of the first through-passage.
