ABSTRACT:
In a gas turbine engine, combustor flame temperature is maintained within predetermined limits by increasing the combustor airflow during periods of increasing fuel flow and by increasing the burner area when the airflow has reached an upper limit. Increases in burner area are countered by decreasing airflow until the airflow reaches a lower limit, at which time the procedure repeats itself. When the fuel flow is decreased, the airflow is reduced until it reaches its lower limit, at which time the burner area is decreased, allowing the airflow to rise to its upper limit, at which time, the procedure repeats itself.
