ROTATING BLADE FOR A GAS TURBINE

A rotating blade (10) for a gas turbine comprises an airfoil (11) extending in a longitudinal direction and having a leading edge (11 a) and a trailing edge (11 b), whereby said airfoil (11) is bordered at its outer end by a tip shroud (14), whereby said airfoil (11) comprises two or more internal p...

Beschreibung
Zusammenfassung:	A rotating blade (10) for a gas turbine comprises an airfoil (11) extending in a longitudinal direction and having a leading edge (11 a) and a trailing edge (11 b), whereby said airfoil (11) is bordered at its outer end by a tip shroud (14), whereby said airfoil (11) comprises two or more internal passages (15a, 15b and 15b), which run in longitudinal direction and are separated by solid webs (23 and 24), and whereby a plurality of shroud fins (18a, 18b and 18c) is arranged on top said tip shroud (14) to improve gas sealing against a corresponding stator heat shield. The stability and life time of the blade are improved by selecting the position of each of said shroud fins (18a, 18b and 18c) to be exclusively above one of said webs (23, 24) and/or a leading edge wall.
