GAS TURBINE ENGINE VARIABLE AREA FAN NOZZLE CONTROL

A method of managing a gas turbine engine (20) operating line includes detecting an air speed (74) and a fan speed. A data table is referenced that includes a desired variable area fan nozzle position based upon air speed (74) and fan speed. The detected air speed (74) and detected fan speed are com...

Zusammenfassung:	A method of managing a gas turbine engine (20) operating line includes detecting an air speed (74) and a fan speed. A data table is referenced that includes a desired variable area fan nozzle position based upon air speed (74) and fan speed. The detected air speed (74) and detected fan speed are compared to the data table to determine a target variable area fan nozzle position. An actual variable area fan nozzle position is adjusted to the target variable area fan nozzle position.
