Abstract (en)
[origin: WO2019115578A1] The invention relates to a vane (1) for a turbomachine rotor comprising a first blade (2) and a second blade (3) arranged to form two successive blades for a bladed rotor, a platform (4) substantially forming an angular wall sector in an axial direction (X), the two blades (2, 3) being connected to the platform (4) by one of the ends thereof extending substantially in a direction referred to as radial (R) which is substantially perpendicular to the axial direction (X), and attachment means connected to the platform (4) which are designed to cooperate with fastening means on a disk (6) of the rotor, characterised in that the attachment means comprise two individual supports (12, 13), each support extending from the platform (4), in the radial direction (R), in the extension of one of the two blades (2, 3), and bearing an attachment member (16, 17) at an end opposite the platform (4), the attachment member extending substantially parallel to the axial direction (X) and having at least one surface (S1, S2) facing the platform (4) with a constant cross-sectional profile perpendicular to the axial direction (X), so as to form a bearing surface for retaining the vane (1) in the radial direction (R) oriented from the platform to the blades (2, 3). The invention further relates to the rotor comprising the vane.
