Multi-blade vane for a turbomachine rotor and rotor comprising same

A vane (1) for a turbomachine rotor having a first blade (2) and a second blade (3). A platform (4) forms an angular wall sector in an axial direction (X), with the two blades (2, 3) connected to the platform (4). Two individual supports (12, 13), extend from the platform (4), and bear an attachment...

Beschreibung
Zusammenfassung:	A vane (1) for a turbomachine rotor having a first blade (2) and a second blade (3). A platform (4) forms an angular wall sector in an axial direction (X), with the two blades (2, 3) connected to the platform (4). Two individual supports (12, 13), extend from the platform (4), and bear an attachment member (16, 17) at an end opposite the platform (4). The attachment member extends parallel to the axial direction (X) and has at least one surface (S1, S2) facing the platform (4) with a constant cross-sectional profile perpendicular to the axial direction (X) to form a bearing surface for retaining the vane (1) in a radial direction (R) oriented from the platform to the blades (2, 3).
