Abstract

Für die Lauf- und Leitschaufeln von Turbomaschinen, insbesondere Gasturbinentriebwerken, wird ein Schaufelblattdesign mit einem definierten Bereich der Skelettlinienwinkelverteilung für die Skelettlinien der in Spaltnähe liegenden Schaufelprofilschnitte angegeben. Mit der in einem bestimmten Bereich zwischen zwei Grenzkurven (7, 8) liegenden erfindungsgemäßen Verteilung der dimensionslosen Skelettlinienwinkel (α) über der Sehnenlänge (1) und dem entsprechenden Skelettlinienverlauf in einem bis zu 30% der Schaufelhöhe erfassenden Teil der Schaufel ist eine vergleichmässigte Druckverteilung gewährleistet, so dass durch den Spalteinfluss bedingte Störungen und Verluste minimiert werden.
