ABSTRACT:
An electronic fuel control for a multi-engine gas turbine engine provides either independent or master-slave operation according to the position of a selector switch. In one position independent speed demand signals are separately compared with independent actual speed signals and the error signals produced are fed to proportional-plus-integral fuel controls. In the other position engine fuel control receives a signal corresponding to the error between 1/2 of the sum of the average speed demand and the actual speed of that engine whereas the other engines fuel control receives only an error signal representing the difference between the two engine speeds.
