民用飞机预测维修技术研究进展

Research Progress in Predictive Maintenance Technology of Civil Aircraft

民机维修理论伴随航空科技进步在不断往前发展,从定时翻修到以可靠性为中心的计划维修,以及先进的视情与预测维修理念。现代民机测试性的发展,特别是系统/结构健康监测技术的发展和成熟,丰富了现有的持续适航概念和方法体系,在确保飞机满足持续适航要求的前提下,飞机由经验化的基于时间的计划维修向更加高效的基于系统/结构实际健康状态的维修转变。本文总结了民用飞机预测维修技术的最新研究进展情况,从以传统计划维修模式为基础引出预测维修模式,包括结构/系统预测维修任务分析方法、预测维修方案优化、预测维修关键技术以及在民机领域的应用情况。

The strategy of civil aircraft maintenance is constantly advancing with the progess of aviation technology,from time-based overhaul to reliability centered scheduled maintenance,as well as advanced condition based and predictive maintenance concepts.The development of modern civil aircraft testability,especially the development and application of system/structural health monitoring technology,has enriched the existing concept and methods of continuous airworthiness.While ensuring that the aircraft meets the requirements of continuous airworthiness,the aircraft has shifted from empirical time-based scheduled maintenance to more efficient maintenance based on the actual health status of the system/structure.This paper summarizes the latest research progress of predictive maintenance technology for civil aircraft,and introduces predictive maintenance mode based on traditional scheduled maintenance,including structural/system predictive maintenance task analysis methods,maintenance plan optimization,key technologies of predictive maintenance,and their applications in the field of civil aircraft.
