民用航空发动机性能故障诊断途径

Fault Diagnosis Approach of Performance for Civil Aeroengine

发动机性能状态监控是保证飞行安全的重要手段。航空专用数据链通信系统(ACARS)和快速数据存取记录器(QAR)已经越来越普遍地被各航空公司所采用。介绍了多个综合利用ACARS、QAR译码巡航报告等信息对V2500发动机进行性能故障诊断的案例,对如何利用多种手段和EHM软件对V2500发动机进行故障诊断作了总结。

Engine Performance Monitoring is extremely important for Flight Safety Assurance. Aircraft Addressing and Reporting System （ ACARS） and Quick Access Recorder （QAR） are adopted more and more widely by the Airlines. Some cases were presented which applied the information of decode cruise reports of ACARS and QAR and etc to perform performance fault diagnosis for V2500 engine. The conclusions of how to use multiple tools and EHM software to perform fault diagnosis for V2500 engine are summarized.
