  • Fuel metering system for a gas turbine engine
    Patent number: 4656827
    Abstract: A fuel metering system for a gas turbine engine is disclosed which includes two rotating flowmeters connected to the fuel supply circuit in parallel. The speed of the flowmeters are controlled by a pair of braking motors and tachometers are provided in each to provide an output signal of their rotational speeds. A control circuit is connected to the system to regulate the speed of the flowmeters to insure that the total fuel flow coincides with a reference value. Should a malfunction occur in one of the flowmeter systems, the control circuit may regulate the speed of the remaining flowmeter to retain the total fuel flow at the reference value.
