Abstract

Ein Verfahren zum Verändern der aerodynamischen Gestalt einer Schaufel (22, 24) einer Gasturbine sieht vor, diese mit einer Beschichtung (42) aus einer Formgedächtnis-Legierung zu versehen. Über Kanäle (32) wird Heißluft (36) zur beschichteten Schaufel (22, 24) transportiert, um eine Phasenänderung der Beschichtung (42) und eine aerodynamische Gestaltänderung der Schaufel (22, 24) herbeizuführen.
