摘要
Stator blading (10) of return channels for two-dimensional centrifugal stages of a multi-stage centrifugal compressor with improved efficiency, of the type comprising a plurality of blades (20) disposed circumferentially equally spaced on a ring (12) which surrounds a rotor of the compressor, these blades (20) each having a cross-section in the shape of a half-moon formed by a concave area (21) and a convex area (22), these concave (21) and convex (22) areas being connected to one another such as to determine a trailing edge (24) and a leading edge (23) on an inner radius (R); the profile of the concave area (21) of each blade (20) is produced by connecting to one another points which have particular Cartesian co-ordinates relative to a system of axes which are at right-angles to one another, of x-co-ordinates (X) and y-co-ordinates (Y) with an origin (O) located on the axis of rotation.
