Abstract
Laufschaufelanordnungen einer Turbine enthalten Schaufelblätter (40), die auf Basen (45) angebracht sind. Die vorderen (47) und/oder hinteren Kanten (49) der Basen sind mit gekrümmten Abschnitten versehen. In gleicher Weise können gekrümmte Abschnitte an Vorder- und/oder Hinterkanten der Engelsflügel einer Turbinenschaufelanordnung vorgesehen sein. Ebenfalls können gekrümmte Abschnitte an den vorderen (57) und/oder hinteren (59) Kanten von Leitschaufelanordnungen einer Turbine vorgesehen sein.
