Rotor blade for centrifugal compressor

摘要

A cylindrical blade for a rotor of the purely radial type of a centrifugal compressor with a medium flow coefficient comprises a first surface (3) of the pressure side and a second surface (5) of the suction side of equal curvature, both having generatrices parallel to the axis (Z) of rotation of the rotor, in which the line of curvature of the said surfaces (3, 5) is defined, in a Cartesian reference system, by the ratio between the coordinates of a discrete set of points belonging to the line and the outer radius (R) of the rotor (10). <IMAGE>
