Abstract
An improved deceleration fuel control system and related method are provided for regulating fuel flow to a combustor of a gas turbine engine to permit deceleration as a maximum rate without risk of combustor blowout. The system includes a controller responsive to combustor air flow and engine shaft speed to calculate a minimum fuel-air ratio to sustain a combustor flame during a maximum rate deceleration condition. The controller then regulates fuel supply to maintain a deceleration fuel-air ratio at a selected safety margin higher than the calculated minimum to sustain combustion.
