Abstract

L'invention concerne un amortisseur d'aubes et un joint d'étanchéité pour turbines. Un organe d'étanchéité 48 est disposé entre le carter 22 d'un moteur à turbine et plusieurs aubes fixes 24, 26. Cet organe d'étanchéité 48 comporte une section centrale flexible 52 qui est comprimée dans la position d'installation. L'invention est utilisée pour améliorer l'étanchéité à l'air extérieur et amortir en même temps les vibrations des aubes fixes dans une turbine.
