摘要:
Airfoil attachment comprising a support (3) and flanks (13, 14) rising on it to delimit a broach compartment (15) designed to receive and hold an airfoil root. The flanks (13, 14) are machined (21, 22) so as to separate the portions (23, 24 and 25) and prevent a complete break of a flank and detachment of the airfoil when a crack develops because the crack is stopped by one of the notches.
摘要:
Wheel (10) of a turbine engine such as an airplane turbojet, including a disk (12) having blades (14) and at least one ring of a metal matrix composite material (20, 22) mounted on the disk (12) in order to take up centrifugal forces during operation, the wheel further including at least one annular flange (28, 30) formed by sections arranged end-to-end and each including a radially internal annular portion applied on a flank (36, 38) of the disk (12) and a radially external portion coming into contact with the ring (20, 22) in order to ensure the axial holding of the latter on the disk (12), and means (32, 34, 40, 42) for radially holding flange sections on the disk.
