ABSTRACT:
An electronic fuel control system for controlling the rate at which fuel is supplied to a gas turbine engine which controls turbine speed, acceleration, and combustor temperature as a function of ambient temperature and turbine speed. A predetermined fuel schedule controls the maximum and minimum amount of fuel supplied to the gas turbine engine during transient and steady-state operation, and sequences operation from a starting fuel schedule to a running fuel schedule. A transient fuel boosting function temporarily overrides the temperature limit control when a speed increase is called for.
