Rotor for low pressure turbine of turbo machine i.e. twin-shaft gas turbine engine, has air fixture comprising holes formed in distributed manner in ferrules of downstream disk to supply air from central opening to slide connections

The rotor has a drum (30) provided with consecutive upstream and downstream turbine disks (6A, 6B). The disks carry radial vane bases (10) that are engaged in cavities of the disks by slide connections (9). A cylindrical flange (20) encloses ferrules (7, 8). An exhaust air fixture comprises a set of...

description	The rotor has a drum (30) provided with consecutive upstream and downstream turbine disks (6A, 6B). The disks carry radial vane bases (10) that are engaged in cavities of the disks by slide connections (9). A cylindrical flange (20) encloses ferrules (7, 8). An exhaust air fixture comprises a set of holes (46) formed in a distributed manner in the ferrules of the downstream disk to supply the exhaust air from a central opening of the disks of the drum in an annular space (21) to the connections between the vane bases and cells of downstream disk. An independent claim is also included for a method for manufacturing a rotor. - Le rotor comporte : au moins un tambour (30) à disques de turbine amont et aval (6A, 6B) associés par leurs viroles respectives (7, 8) et portant, par des liaisons (9), les aubes radiales (10) ; un flasque cylindrique (20) entourant lesdites viroles et formant étanchéité avec les aubes (17) d'un disque redresseur de stator situé entre lesdits disques (6A, 6B) ; et un agencement d'air de ventilation pour lesdites liaisons (9) défini par l'amenée d'air dans l'espace annulaire (21) entre ledit flasque et ledit tambour en direction desdites liaisons. - Avantageusement, ledit flasque cylindrique (20) et lesdites viroles (7, 8) des disques amont (6A) et aval (6B) dudit tambour sont assemblés entre eux par soudage de manière à former une seule et même pièce.
