航空发动机状态监控和故障诊断系统

AEROENGINE CONDITION MONITORING AND FAULT DIAGNOSIS SYSTEM

本文从世界各航空公司采用和研制该系统的情况,和我国民航维修工作的现状及发展提出了研究此系统的必要性,对发动机参数趋势分析和气路分析以及发动机振动分析进行了较全面的讨论,提出了研究的途径和基本模型及所要达到的目的。

The study of aeroengine condition monitoring a玠 fault diagnosis system is one of the important problems for improving the civil aviation maintenance service in our country, The purpose of the study is to assure (light safety, raise engine utilization ratio, increase economic and social benefit and reduce maintenance cost. Such a study will certainly bring about a great advance of civil aviation of China. The necessity of the study presented in this paper is based on the use and development of the system in the world airlines and the maintenance service of civil aviation in our country. The engine parameter trend analysis, gas passage analysis and the esgine vibration analysis are discussed more comprehensively. The study approach and the basic model are also presented.
