航空发动机状态监控系统研究

航空发动机的维修方式正在由定期维修向视情维修转变,可以在保证发动机可靠性的前提下,降低发动机的维护费用。状态监控系统的研究是开展航空发动机视情维修的关键步骤。借鉴国外典型的发动机状态监控系统,提出了发动机状态监控系统的结构、功能需求、监控事件的选择,实现了机载状态监控系统的原理样机及其仿真平台,对状态监控系统的研究有一定意义。

Study on Aeroengine Condition Monitoring System

Aeroengine maintenance mode was transferred from the pre-scheduled maintenance to the condition-based maintenance.The condition-based maintenance can help to improve the engine reliability and reduce the maintenance costs.The study of the condition monitoring system was the key step of the condition-based maintenance.Firstly,the foreign experience of aeroengine condition monitoring system was learned.The structure,functional requirements and selection of monitoring events were proposed for a condition monitoring system,and then the principle prototype and its simulation platform of airborne condition monitoring system were implemented,which was helpful to the condition monitoring system study.
