  • Multivariant set point using N1 and N2 for engine control
    Publication number: 20030110759
    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.

  • Smart surge bleed valve system and method
    Publication number: 20020170295
    Abstract: A method and a system is provided for reducing aircraft engine fuel consumption by selectively closing an aircraft surge bleed valve (SBV), when the surge bleed valve would normally be open. The method determines whether the engine bleed flow obtained with the closed SBV is sufficient to prevent engine surge for the present flight regime. If so, the SBV is kept closed, while the aircraft is drawing air from the engine.
