战斗机故障预测与健康管理技术应用的思考

Research on Application of Prognostics and Health Management Technology for Fighter Aircraft

从装备维修保障能力发展需求及故障预测与健康管理(PHM)技术内涵入手,根据主要武器装备的作战使用及维修特点,分析了战斗机应用PHM技术的迫切需求以及国内外PHM技术工程应用现状和特点;重点研究给出了战斗机PHM系统研制过程中关于需求识别、软硬件统筹、系统架构设计与能力提升、分层级诊断体系构建、功能系统对象权衡确定等5个关键环节的解决思路;结合国内某型新机PHM系统的应用场景阐述了战斗机PHM系统研制效果;最后对未来战斗机PHM技术发展和应用方向进行了展望。

From the perspective of the development requirements for equipment maintenance&support capabilities and the connotation of prognostics and health management(PHM)technology,the paper analyzes the urgent demands,marked effects and interlinked tradeoff for the PHM application on fighter aircraft based on its unique characteristics in the operation and maintenance modes from other types of military equipment.It reviews the current research status and features of PHM engineering application at home and abroad,and highlights the solutions in five key links during the development process of PHM system on fighter aircraft.They are respectively identification of system requirement,planning&integration of software and hardware,design and upgrade of system architecture,construction of hierarchical diagnosis system,as well as tradeoff determination of functional system objects.Furthermore,the application effects of PHM system development on fighter aircraft are elaborated in light of its application scenarios on a new type of domestic fighter,and thus the future development direction of PHM technology application on fighter aircraft is proposed.
