Abstract

Pour limiter le chargement statique d'une aube mobile de turbomachine d'aéronef, l'invention prévoit une pale (28) ainsi qu'un talon (34) comportant une base (36) et au moins un organe d'étanchéité (38) faisant saillie radialement vers l'extérieur à partir de la base (36). De plus, le talon (34) est monté radialement mobile sur une tête (32) de la pale (28).
