    • Variable elements of a turbine engine such as variable inlet guide vanes, variable bleed valves and variable stator vanes can be adjusted to provide a desired level of power and/or efficiency for the turbine engine across a range of operating conditions. The variable element settings typically determined through experimentation when the engine is new. Unfortunately, over the life cycle of the turbine engine, as wear occurs, the original variable element settings may no longer provide a desired level of power and efficiency. To correct this problem, offsets to the original variable element settings are calculated based on observable operational conditions which provide a measure of the wear that has occurred. The offsets are applied to the original variable element settings to generate corrected variable element settings. These corrected variable element settings are then used to configure the turbine engine. The corrected variable element settings allow the turbine engine to continue to operate at a desired level of power and/or efficiency over the life of the turbine engine, despite any deterioration which may have occurred due to normal life cycle wear.
    • 涡轮发动机的可变元件,例如可变入口导向叶片,可变放气阀和可变定子叶片可以被调节以在涡轮发动机的一系列操作条件下提供期望水平的功率和/或效率。 当发动机是新的时,通常通过实验确定可变元件设置。 不幸的是,在涡轮发动机的生命周期中,随着磨损发生,原始可变元件设置可能不再提供期望的功率和效率水平。 为了纠正这个问题,原始可变元件设置的偏移是基于可观测的操作条件计算的,这些操作条件提供了已经发生的磨损量度。 偏移量应用于原始可变元件设置以生成校正的可变元件设置。 然后将这些校正的可变元件设置用于配置涡轮发动机。 校正的可变元件设置允许涡轮发动机在涡轮发动机的使用寿命期间继续以期望的功率水平和/或效率运行,尽管由于正常的生命周期磨损而可能发生的任何劣化。
