  • Compressor inlet guide vane flow based anti-ice formation control system and method
    Patent number: 7874161
    Abstract: A system and method are provided for effectively removing ice that may have formed on gas turbine engine compressor inlet guide vanes and/or preventing, or at least inhibiting, reformation of ice on gas turbine engine compressor inlet guide vanes after the ice has been removed. A determination is made as to whether flow through the compressor is below a predetermined flow value. If the flow through the compressor is below the predetermined flow value, then the inlet guide vanes are repeatedly moved between at least two predetermined positions to remove ice and/or prevent, or at least inhibit, reformation of ice on the inlet guide vanes.
    Type: Grant

  • Compressor inlet guide vane de-ice control system and method
    Patent number: 7762081
    Abstract: A system and method are provided for effectively removing ice that may have formed on gas turbine engine compressor inlet guide vanes and/or preventing, or at least inhibiting, reformation of ice on gas turbine engine compressor inlet guide vanes after the ice has been removed. A determination is made as to whether actual inlet guide vane position differs from the commanded inlet guide vane position by a predetermined amount. If so, then the inlet guide vanes are repeatedly commanded to move in at least two predetermined directions to remove ice that may have formed on the inlet guide vanes.
