摘要： The present invention provides a method of operating an aircraft whereby actual acceleration of an aircraft is used as the direct measure of the capability of the aircraft to takeoff. Thus, a minimum takeoff acceleration is determined for an aircraft and then through appropriate sensing means for acceleration, actual acceleration of the aircraft is determined and compared with that predetermined minimum takeoff acceleration. If the actual aircraft acceleration exceeds the minimum takeoff acceleration then an indication such as a buzzer or signal is provided. The present method may also be used in cooperation with existing takeoff determining systems utilising engine thrust as the means of determining aircraft capability to takeoff. The authority of the various aircraft takeoff criteria can be adjusted as required. Furthermore, the present aircraft acceleration regime may be utilised with regard to adjusting existing engine thrust means for determining takeoff or cruise capability.

摘要： In a method for determining the free field thrust of a gas turbine engine the gas turbine engine is attached to a movable support means in an enclosed gas turbine engine test facility, and is operated at a selected engine operating point. The thrust applied by the engine to the thrust cradle is measured via thrust measurement means. Calculations are performed to determine the gas turbine engine intake momentum drag generated by airflow into the gas turbine engine intake, the thrust cradle drag force generated by airflow past the moveable support means of the thrust cradle, the base drag generated as a result of accelerating nozzle ejector airflow, a pre-stream tube force related to turning of stream lines in the intake air path, a pre-stream tube force related to a bell mouth pull-off force. Also forces due to forward anemometer plane and nozzle static pressures and a nozzle exit buoyancy force and determined, and all of these forces are summed according to their respective positive and negative values to determine the free field thrust of the engine at the selected engine operating point.

摘要翻译：本发明提供了一种操作飞机的方法，借此飞机的实际加速度被用作飞机起飞能力的直接量度。因此，为飞机确定最小起飞加速度，然后通过用于加速度的适当感测装置确定飞行器的实际加速度并与该预定最小起飞加速度进行比较。如果实际飞机加速度超过最小起飞加速度，则会提供蜂鸣器或信号等指示。本方法还可以与现有的利用发动机推力的起飞确定系统一起用作确定飞机起飞能力的手段。各种飞机起飞标准的权力可以根据需要进行调整。此外，可以利用当前的飞机加速状态来调整用于确定起飞或巡航能力的现有发动机推力装置。

摘要： A turbofan gas turbine engine (10) comprises a variable area exhaust nozzle (12) arranged at the downstream end of a casing (17). A control unit (66) analyses the power produced by the gas turbine engine (10), the flight speed of the gas turbine engine (1) and/or the altitude of the gas turbine engine (10). The control unit (66) configures the variable area nozzle (12) at a first cross-sectional area (70A) when the flight speed of the gas turbine engine (10) is less than a first predetermined value. The control unit (66) configures the variable area nozzle (12) at a second, smaller, cross-sectional area (70B) when the flight speed of the gas turbine engine (10) is greater than the first predetermined value and the power produced by the gas turbine engine (10) is greater than a second predetermined value. The control unit (66) configures the variable area nozzle (12) at a third, intermediate, cross-sectional area (70C) when the flight speed of the gas turbine engine (10) is greater than the first predetermined value and the power produced by the gas turbine engine (10) is less than the second predetermined value.
