GAS TURBINE ENGINE VARIABLE AREA FAN NOZZLE CONTROL |
| 摘要 |
A method of managing a gas turbine engine includes the steps of detecting an airspeed and detecting a fan speed. A parameter relationship is referenced related to a desired variable area fan nozzle position based upon at least airspeed and fan speed. The detected airspeed and detected fan speed is compared to the parameter relationship to determine a target variable area fan nozzle position. An actual variable area fan nozzle position is adjusted in response to the determination of the target area fan nozzle position and at least one threshold. |

1. A method of managing a gas turbine engine comprising the steps of:
detecting an airspeed; detecting a fan speed; referencing a parameter relationship related to a desired variable area fan nozzle position based upon at least airspeed and fan speed, and comparing the detected airspeed and detected fan speed to the parameter relationship to determine a target variable area fan nozzle position; and adjusting an actual variable area fan nozzle position in response to the determination of the target area fan nozzle position and at least one threshold. |
