Abstract (en)

[origin: WO2016041761A1] The invention relates to a turbine blade (1) having an internally cooled turbine blade airfoil (3) in which a hollow space (10) is divided by rib elements (11, 12) into at least one cooling duct (13) carrying a coolant, wherein in at least one of the rib elements (11, 12) means (33) are disposed for producing a separating tear (30) which extends at least partially in the longitudinal direction (29) of the at least one rib element (11, 12) .

Abstract (de)

Die Erfindung betrifft eine Turbinenschaufel (1) mit einem innengekühlten Turbinenschaufelblatt (3), in welchem ein Hohlraum (10) durch Rippenelemente (11, 12) in wenigstens einen Kühlmittel führenden Kühlkanal (13) unterteilt ist, wobei in wenigstens einem der Rippenelemente (11, 12) Mittel (33) zum Erzeugen eines sich in Längsrichtung (29) des wenigstens einen Rippenelements (11, 12) zumindest teilweise erstreckenden Teilungsrisses (30) angeordnet sind.
