Assesment of on-wing engine health based on non-linear dynamic engine behaviour

在过去10年中，航空航天部门的预测健康检测领域取得了重大进展，其中大部分好处来自航空发动机性能恶化的预测。尚未开发的领域是预测结构动力学行为恶化，从而导致发动机意外维护。该计划的目的是开发一种新的方法，基于对发动机在翼上的非线性行为的传感，作为发动机异常劣化的衡量标准。然后，所开发的技术将被提交给核查和确认程序，其目的是使其能够向适航当局申请维修积分，并促进在资产管理中使用剩余使用寿命预测。该项目提供预测算法和决策技术。

There have been significant developments over the last 10 years in the field of predictive health sensing in the aerospace sector, with the majority of benefits realised from the prediction of aero engine performance deterioration. The area that has not yet been developed is the prediction of deterioration in the structural dynamics behaviour leading to unplanned engine maintenance. The purpose of this program is to develop a novel approach based on the sensing of non linear behaviour of engines on-wing as a measure of abnormal engine deterioration. The techniques developed will then besubjected to a verification and validation program designed so that it will act as an enabler to claim maintenance credits with the airworthiness authorities and facilitate the use of prediction of remaining useful life in the management of assets. This project provides predictive algorithm and decision making techniques.
