Abstract

L'invention concerne une roue mobile de turbomachine à aubes en matériau composite, comportant un flasque de montage (4), une pluralité d'aubes (16) en matériau composite montées sur le flasque de montage, chaque aube ayant un talon (20) en sommet muni de léchettes (22), un disque d'orientation (28) fixé coaxialement autour du flasque de montage et comprenant à sa périphérie extérieure une pluralité de fentes axiales ouvertes à une extrémité, chaque fente présentant une section transversale adaptée à la section transversale d'un pied (18) d'aube afin de le maintenir angulairement par coopération de forme, et un anneau ressort à diamètre variable (38) logé en partie dans une encoche axiale (26) formée dans chaque pied d'aube et faisant saillie axialement par rapport à celui-ci, l'anneau ressort étant apte à venir en butée radiale contre une surface interne (34a) du disque d'orientation lors d'un déplacement radial des aubes vers l'extérieur du flasque de montage.
