AIRCRAFT VAPOUR TRAIL CONTROL SYSTEM |
| 摘要 |
The invention concerns an aircraft propulsion control system in which a gas turbine engine has an actuable flow opening for control of flow to or from a portion of the engine. One or more sensor is arranged to sense a condition indicative of vapour trail formation by the exhaust flow from the engine. A controller is arranged to control actuation of the flow opening so as to reduce the efficiency of the engine upon sensing of said condition by the one or more sensor. In one example, the flow opening is a variable area fan nozzle. |

1. A method of controlling one or more gas turbine engine of an aircraft, comprising sensing a condition indicative of vapour trail formation by the exhaust flow from the engine using one or more sensor and controlling actuation of a flow opening for a propulsive fan of the engine so as to reduce the efficiency of the engine upon sensing of said condition by the one or more sensor. |
