초록

A system for controlling the flow of fuel to a gas turbine engine is operable in at least two modes. In a first mode, the flow rate of fuel supplied from a fuel source to the combustors of the turbine engine is controlled by modulating the position of a metering valve. A controller determines the controllability of the metering valve and, if it is determined to be non-controllable, then the system is operated in the second mode. In the second mode, the flow rate of fuel supplied to the combustors is controlled by modulating the position of a bypass valve...

1. A method of controlling fuel flow from a fuel source to a gas turbine engine combustor, comprising: supplying fuel from the fuel source to a supply line; directing a first fraction of the fuel from the supply line, through a metering valve having a first variable area flow orifice, to the combustor; directing a second fraction of the fuel from the supply line, through a bypass valve having a second variable area flow orifice, to the fuel source; determining whether the metering valve is controllable or non-controllable; and controlling fuel flo...
