ABSTRACT:
A compressor or turbine rotor stage includes a wheel with a circumferential slot for retention of the roots of blades mounted on the wheel. Each side of the rim of the wheel is approximately symmetrical about a line parallel to the axis of rotation of the wheel through the centroid of the section of the rim side and is of such asymmetrical configuration about a line normal to the axis of rotation that the shear center of each side of the rim is inboard of the centroid and preferably close to or inboard of the plane of action of the radial component of the forces exerted by the blade roots on the sides of the rim due to the centrifugal force pull of the blades.
