Abstract
Dispositif éliminant tout mouvement relatif entre la queue d'aronde de l'aube et le disque de rotor pendant les différents régimes de marche normaux du moteur. Il comprend une cale métallique d'écartement 52 en forme d'arc introduite sans déformation dans l'espace entre le pied 18 de l'aube et le fonde de la fente du rotor 12 et qui, une fois introduite est déformable pour porter sur le pied de façon à lui appliquer une charge orientée vers l'intérieur, et un organe de blocage 54 que l'on peut introduire sous la cade d'écartement pour maintenir cette cale à l'état déformé après son introduction dans la fente du rotor. Application aux turbomachines.
