  • Vane and throat shaping
    Patent number: 7255530
    Abstract: An exemplary vane for a radial turbine assembly includes a hub end and a shroud end that define vane height, a leading edge and a trailing edge that define vane length along a camberline and an inner surface and an outer surface that extend from the hub end to the shroud end and meet at the leading edge and the trailing edge and that define vane thickness wherein, for at least a portion of the vane, vane length and vane thickness vary with respect to vane height. Other exemplary vanes, assemblies, methods, etc., are also disclosed.
    Type: Grant
    Filed: December 8, 2004
    Date of Patent: August 14, 2007
    Assignee: Honeywell International Inc.
    Inventors: Costas Vogiatzis, Nidal A. Ghizawi
  • Profiled blades for turbocharger turbines, compressors, and the like
    Patent number: 7147433
    Abstract: A rotor and an apparatus including a rotor are provided. For example, the apparatus can be a turbine or compressor having a housing in which the rotor rotates while gas is circulated therethrough. The rotor has a plurality of radially extending blades, and each blade defines a nonlinear profile along at least one edge so that the strains induced in the blade during operation are reduced. A method for manufacturing such a rotor is also provided.

  • Ejector-based cooling system for turbochargers
    Patent number: 6668553
    Abstract: A turbocharger component cooling system employs an ejector using energizing gas from the turbocharger system to draw cooling fluid through a plenum around the component to be cooled into the secondary inlet of the ejector and dumping the combined energizing and cooling gas flows into a low pressure dump. Energizing gas is drawn from the high pressure side of the compressor or turbine flows in the turbocharger and returned to the low pressure side in the same flow.
