Abstract: This invention relates to the operation of gas turbine engines, and in particular to determining deterioration of components during operation. In a specific embodiment, the invention is concerned with determining the actions to be taken when a foreign body impact has been detected, for example on a fan blade.Accordingly, the invention provides a method to take one or more FOD detection apparatus, analyse the likely (probabilistic) outcome, and provide a system to determine subsequent action that assures safety whilst minimising operational disruption.This invention provides a method and apparatus to identify FOD or bird impact to gas turbine fan blades, assessing the damage that may have occurred whist still in flight and determining post impact actions, including replacement parts.

Abstract translation: 本发明涉及燃气涡轮发动机的操作，特别涉及确定操作期间部件的劣化。 在具体实施例中，本发明涉及确定在检测到异物撞击时所采取的动作，例如在风扇叶片上。 因此，本发明提供了一种采用一个或多个FOD检测装置，分析可能（概率）结果的方法，并且提供一种系统来确定确保安全性的后续动作，同时最小化操作中断。 本发明提供了一种用于识别对燃气涡轮风扇叶片的FOD或鸟类影响的方法和装置，评估可能在飞行中发生的损坏以及确定后冲击动作（包括更换部件）。
