CA 2206980

Gas turbine blades (14) are slid axially into disc (12) with a retention tang (22) on each blade abutting the disc. An axially extending space (18) between blade platforms (26) and the disc receives elongated strip (30). With prebent end (34) resiliently held against the disc the opposite end (36) is bent radially outward against the roots of adjacent blades. A bow (38) biases the blades outwardly, deterring vibration.

La présente invention concerne un système de maintien d'aubes (14) de turbines à gaz, qui sont glissées axialement dans le disque (12), avec une languette de maintien (22) sur chaque aube, qui s'appuie contre le disque. Un espace axial (18), entre les nageoires (26) des aubes et le disque, reçoit un feuillard (30). L'extrémité pliée d'avance (34) étant maintenue élastiquement contre le disque, l'extrémité opposée (36) est pliée radialement vers l'extérieur, contre les embases des aubes voisines. Un partie arquée (38) pousse les aubes vers l'extérieur, ce qui prévient les vibrations.
