  • Multivariant set point using N1 and N2 for engine control
    Patent number: 6931835
    Abstract: A method for selecting a setpoint for a turbofan engine having a fan speed and a core idle speed scheduling includes determining a weighting factor based upon a throttle lever position, the weighting factor being zero in an idle region and ranging from zero to one in a dead band region and applying the weighting factor to an output of a fan speed governor and to an output of a core speed governor to select the setpoint.
    Type: Grant
    Filed: May 5, 2003
    Date of Patent: August 23, 2005
    Assignee: Honeywell International, Inc.
    Inventors: Gregory J. Chapman, John J. Rushinsky
  • System and method for generating consolidated gas turbine control tables
    Patent number: 6778884
    Abstract: A method for generating a power setting parameter table. The method includes the steps of generating an index from a plurality of first and second inputs and determining a power setting parameter corresponding to each index and second input. The first inputs may include flight speed and temperature values and the second inputs may include altitude values.

  • Multivariant set point using N1 and N2 for engine control
    Patent number: 6688097
    Abstract: A turbofan engine throttle control system and method for eliminating dead bands in the throttle control by decreasing and increasing the fuel flow to the engine during transition from the scheduled core speed to scheduled fan speed of the engine to effect a smooth and continuous transition from the core speed to the fan speed and vice-versa. A signal is generated to open and close a valve system to augment and decrease the fuel flow in response to sensing different throttle lever angles.
