Abstract
An electronic fuel control for a gas turbine engine monitors the mass density of the fuel. As the mass density of the fuel varies when the fuel temperature changes or when the fuel type changes, the electronic fuel control adjusts an initial mass density to a corrected value based on the most recent measurement of mass fuel flow that was taken when the mass fuel flow measurement was known to be accurate. Accurately controlling mass fuel flow permits gas turbine engine designers to reduce tolerances in moving parts which improves the efficiency of the gas turbine engine.
