| 发明名称 | Scheduling of variable area fan nozzle to optimize engine performance | ||
| 摘要 | A disclosed control system for a gas turbine engine includes a controller configured to set a position of the variable area fan nozzle according to a predetermined schedule of variable area fan nozzle positions corresponding to a flight operating condition. The schedule is determined in view of a relationship between a position of the variable area nozzle and a performance level of the engine at current flight conditions. | ||

| 主权项 | 1. A control system for a gas turbine engine comprising: a fan nacelle including variable area nozzle for regulating airflow through a bypass duct; an actuator coupled to the variable area nozzle for regulating air flow by positioning the variable area nozzle; and a controller configured to set a position of the variable area fan nozzle according to a predetermined schedule of variable area fan nozzle positions corresponding to a flight operating condition, wherein the flight operating condition includes an amount of bleed air demand into an environmental control system within an aircraft, wherein the predetermined schedule includes a plurality of variable area fan nozzle positions determined to produce a value of an engine performance parameter at the flight operating condition. | ||
