Abstract

L'ASSEMBLAGE DE ROTOR POUR TURBOMACHINE A UNE VITESSE CRITIQUE SITUEE BIEN AU-DESSUS DE LA VITESSE DE FONCTIONNEMENT DE L'ASSEMBLAGE DU ROTOR. LA CONSTRUCTION DU ROTOR AMELIORE LA RIGIDITE AXIALE DE L'ASSEMBLAGE DE ROTOR 18 ET COMPORTE UN MOYEN POUR PROTEGER UNE PARTIE DU DISQUE DE ROTOR 36 CONTRE LES GAZ DU MILIEU DE TRAVAIL. L'ASSEMBLAGE DE ROTOR A UN ELEMENT EN TRONC DE CONE 30 POUR RELIER LE DISQUE A L'ARBRE DE L'ASSEMBLAGE DE ROTOR.
