Abstract

Eine Fanschaufel für ein Gasturbinentriebwerk, die eine Tragstruktur (2) aus Faserverbundmaterial aufweist, ist nur im Bereich des Schaufelblattes (3) von einer metallischen Hüllstruktur (4) aus Blech umgeben, so dass die am Schaufelfuß (11) wirkenden Kräfte und Spannungen und die Delaminationsgefahr durch hohe Biegebelastung im Übergangsbereich zwischen Schaufelblatt und Schaufelfuß minimiert werden.
