Abstract
A gas turbine engine fuel control system has a metering device which is controlled by the delivery pressure of the engine compressor, and an arrangement for modifying flow through the metering device in accordance with the difference between a calculated value of the pressure rise across the compressor, and a measured value of this pressure rise. The calculated value is obtained from a compound cam which is positioned in accordance with desired engine thrust and with one of the compressor pressures and is profiled in accordance with desired values of the other pressure. Movement of a cam follower is compared with a sensed value of the other pressure and used to modify fuel flow.
