ROTATING BLADE FOR A GAS TURBINE |
| 摘要 |
A rotating blade for a gas turbine includes an airfoil extending in a longitudinal direction and having a leading edge and a trailing edge, whereby the airfoil is bordered at its outer end by a tip shroud, whereby the airfoil includes two or more internal passages, which run in longitudinal direction and are separated by solid webs, and whereby a plurality of shroud fins is arranged on top of the tip shroud to improve gas sealing against a corresponding stator heat shield. The stability and life time of the blade can be enhanced by selecting a position of each of the shroud fins to be exclusively above one of the webs and/or a leading edge wall. |

1. Rotating blade for a gas turbine, comprising: an airfoil extending in a longitudinal direction and having a leading edge and a trailing edge, whereby said airfoil is bordered at its outer end by a tip shroud, whereby said airfoil includes two or more internal passages, which run in the longitudinal direction and are separated by solid webs, and whereby a plurality of shroud fins is arranged on top of said tip shroud to improve gas sealing against a corresponding stator heat shield, wherein a position of each of said shroud fins is selected to be exclusively above one of said webs and/or a leading edge wall. |
