Abstract
A method of providing a slim-line nacelle for a gas turbine engine includes the steps of detecting a windmilling condition and increasing a discharge airflow area of a variable area fan nozzle in response to the detection of the windmilling condition.
Claims15
A method of achieving a slim-line nacelle on a gas turbine engine, comprising the steps of:
- (a) sensing a windmilling condition;
- and
- (b) increasing a discharge airflow area of a variable area fan nozzle in response to the windmilling condition from the sensing step.
A method of achieving a slim-line nacelle on a gas turbine engine, comprising the steps of:
- sensing an operability condition;
- increasing a discharge airflow area of a variable area fan nozzle;
- and introducing an airflow near an inlet lip section of the gas turbine engine, wherein the steps of increasing and introducing are performed in response to the operability condition from the sensing step to achieve the slim-line nacelle.
