Abstract

Une partie de pale (12) d'une aube est assemblée à une partie de plate-forme (11) par une insertion dans une empreinte (14) de celle-ci, en direction latérale depuis une ouverture de l'empreinte, l'empreinte étant munie d'une paroi de fond (21) sur au moins une partie de sa superficie. La superficie de collage entre les parties de l'aube (11, 12) est accrue.
