| 摘要 |
This invention relates to the operation of gas turbine engines (10), 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 (2). 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 (2), assessing the damage that may have occurred whist still in flight and determining post impact actions, including replacement parts. |
