Analysis on Integrated Design of Military Aircraft Prognostic and Health Management(PHM)System

Abstract

The design and engineering application of prognostic and health management(PHM)system for military aircraft has the problems of design standards deficiency,high complexity and low accuracy.The three-dimensional multiphase iterative design criterion is proposed by design requirements analysis of data,structure and function dimensions of PHM system.A three-in-one design architecture is proposed,which is combined with real-time health management based on embedded system,knowledge logic visualization based on knowledge graph,and PHM system modeling based on model-based system engineering(MBSE).The results show that the design architecture achieves 5.63 times of acceleration and 82.7% reduction of power consumption,and improves the traceability of PHM system knowledge and design requirement management.
