A fusion technique taking into account the multi-phase and non-linear characteristics of the aero-engine degradation is adopted to calculate the health level of the aero-engine.A performance model is established based on the thoughts of particle filter and the time-varying parameters of the model are estimated by particle filter algorithm.In addition, the remaining useful life of aero-engine is effectively predicted, which may attribute to the research of remaining useful life prognostics for aero-engine.%针对航空发动机剩余寿命预测问题,采用多参数分阶段非线性的融合方法计算了发动机性能指标,结合粒子滤波思想建立了发动机性能衰退模型,借助粒子滤波预测估计了模型的时变参数,有效预测了发动机的剩余寿命,有利于航空发动机剩余寿命预测方法的研究.
