Abstract (en)
[origin: WO2022171946A1] Assembly (1) comprising a body (10) extending around a central axis (X-X), the body (10) having an outer surface (14) from which a plurality of blades (20) extend, each of the blades (20) having a blade root (22) and a blade tip (24) defining an inner radial end and an outer radial end of the blade (20) relative to the central axis (X-X), the blades (20) having the same blade height (H) measured radially relative to the central axis (X-X), characterised in that each of the blades (20) is connected to the body (10) by its blade root (22) via a connection (30) having a non-zero connection height such that, for the plurality of the blades (20), the connection height of two successive blades (20) is different.
