Abstract
Ein Gasturbinenleitschaufelabschnitt (100) einer Gasturbine weist eine innere Endwand (114) mit einer Vorderkante (115) auf. Ein Serpentinenkanal (116) ist im Wesentlichen innerhalb der Vorderkante (115) eingerichtet. Der Serpentinenkanal (116) weist einen Einlass und einen Auslass auf. Luft kann an dem Einlass (118) aufgenommen und unter Kühlung der Vorderkante (117) an dem Auslass (119) ausgegeben werden.
