A Particle Filtering Approach for Aircraft Structure Life Prediction

As an important part of aircraft systems, accurate grasp of aircraft structure's health condition has become increasingly important. Remaining life prediction is playing an important role in structure health condition assessment. As one of the most popular and effective forecast algorithm, particle filtering method was used to predict the remaining life of aircraft structure. In this paper, we first studied particle filtering algorithm, and analyzed the degradation mechanism of aircraft structure life. Then, we established a remaining life prediction method based on particle filtering algorithm. In the last, case studies are presented to demonstrate the applicability of the particle filtering algorithm for remaining life prediction of aircraft structure.
