  • Turbodrill with asymmetric stator and rotor vanes
    Patent number: 7448455
    Abstract: A turbodrill has rotor vanes and stator vanes that are asymmetric with respect to each other. The rotor blade on which the rotor vanes are disposed has a reaction of less than about 0.5. A method of designing a turbodrill comprises optimizing a first design of stator vanes and optimizing a second design of rotor vanes using computational fluid analysis.
    Type: Grant
    Filed: November 4, 2005
    Date of Patent: November 11, 2008
    Assignee: Smith International, Inc.
    Inventors: Mark Natanael, Kenneth M. Nevlud, Timothy P. Beaton, James Beylotte
