ABSTRACT:
The present invention provides a method of maintaining fan airflow at 100% for throttle transients from 100% military power to 30% thereof by increasing exhaust nozzle area as the fuel flow the engine decreases until the exhaust nozzle reaches its fully open position. Subsequent reductions in fuel flow produce a commensurate reduction fan airflow.
