Abstract
L'invention concerne un dispositif antivibratoire pour les aubes mobiles d'une soufflante canalisée de moteur à turbine à gaz. Chaque aube 13 comporte, à une certaine distance de son pied 12, deux plateaux latéraux 14 orientés circonférentiellement, sans contact avec les plateaux identiques des aubes contiguës. Un amortisseur 16, en matière élastomère renforcée d'éléments métalliques élastiques 20, intercalé entre chaque paire d'aubes en dessous des plateaux adjacents de ces dernières, est appliqué contre ces plateaux par la force centrifuge pendant la rotation de la soufflante de façon à absorber les vibrations des aubes.
