  • Rotor blade for a compressor and compressor having such a rotor blade
    Patent number: 10012235
    Abstract: A rotor blade of an axial compressor includes: a blade root; and a blade leaf. The blade leaf has: a flow inlet edge, a flow outlet edge, a pressure side extending between the flow inlet edge and the flow outlet edge and a suction side extending between the flow inlet edge and the flow outlet edge, which together define a blade profile of the blade leaf in Cartesian coordinate values x, y and z such that first and second profile coordinates, or the coordinates x and y when joining via continuous arcs, each describe a smooth profile section on a radial section height along a third profile coordinate, or the coordinate value z, and the joining of the radial profile sections with a smoothing function describe the blade profile of the blade leaf.

  • Compressor arrangement
    Patent number: 9752584
    Abstract: A compressor arrangement has a common shaft, an axial compressor having at least a single-stage, and a radial compressor having at least single-stage. Assemblies of the, or each, axial compressor stage on the rotor side and assemblies of the, or each, radial compressor stage on the rotor side are attached to a common shaft (4). A ratio between a maximum diameter of the shaft (4) in the region of the axial compressor (2) and a minimum radial impeller seat diameter of the shaft (4) in the region of the radial compressor (3) is between 1.5 and 3.0.
