Abstract
L'invention concerne une roue mobile (1) de turbomachine à aubes en matériau composite, comportant un disque glissière (10) comprenant à sa périphérie extérieure une rainure circonférentielle (12) dont l'ouverture est plus étroite que son fond, une pluralité d'aubes (100) en matériau composite ayant chacune un pied d'aube (102) engagé dans la rainure du disque glissière et présentant une section longitudinale adaptée à la section longitudinale de la rainure du disque glissière afin d'y être maintenu radialement par coopération de forme, et un disque d'orientation (200) fixé coaxialement autour du disque glissière et comprenant à sa périphérie extérieure une pluralité de fentes axiales (208) ouvertes à une extrémité, chaque fente présentant une section transversale adaptée à la section transversale d'un pied d'aube afin de le maintenir angulairement par coopération de forme.
