INTEGRATED ENGINE CONTROL SYSTEM FOR A GAS TURBINE ENGINE

摘要

An engine control system and method for monitoring and controlling operation of a gas turbine engine. The system comprises a fuel metering device having a fuel pump, drive means for driving the fuel pump, a flow meter, and control means for utilizing a flow meter signal to control the speed of the drive means and pump. A tachometer may be utilized as a secondary feedback mechanism under certain predetermined operating conditions. Furthermore, a third feedback mechanism in the form of a metering valve and valve position sensor may be used to provide a triple-redundant feedback system. An oil metering device is utilized for monitoring and controlling the flow of oil in a gas turbine engine. The oil metering device includes an oil pump, drive means for driving the oil pump, and control means for controlling the speed of the drive means and pump. Similar to the fuel metering device, the oil metering device may comprise one or more of the noted feedback systems to control the oil flow rate. The electric fuel pump, electric oil pump, and control means are all collocated in one area of the engine, preferably the jet core housing.
