As a main power component, aircraft engine is a device with extremely high safety and reliability requirements, the engine’s failure often leads to failure of the whole flight system. The engine’s reliability and safety can be expressed by the engine’s remaining useful life (RUL), and RUL prediction the technology has widely used in aircraft engine. However, the engine usually subject to internal forces and imposed external sources under the complex environment, a fault may occur in degradation process. The occurrence of the fault will accelerate the degradation rate, causing the engine’s RUL shorten, so the general prediction method is not a good choice for aircraft engine. In this paper, we present a novel remaining useful prediction approach for aircraft engine considering a fault may occur in its degradation process. Finally, a case study is presented to demonstrate our method can improve the prediction accuracy.
