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.

Figure imgaf001
A fan blade for a gas turbine engine, which has a support structure (2) made of fiber composite material, is surrounded only by a metal sheath structure (4) made of sheet metal in the area of the airfoil (3), so that the forces and stresses acting on the blade root (11) and the Danger of delamination due to high bending load in the transition region between the blade and the blade root can be minimized.
