航空发动机整机试验性能故障诊断系统设计研究

Design of Fault Diagnosis System for Aeroengine Test Performance

航空发动机具有鲜明的精密性、复杂性特征,起初以活塞式发动机最为常见,现经长时间的发展、进步,生产制造体系进一步完善,涡扇、涡轮螺旋桨式发动机等逐渐登上历史舞台,在军事、民用等领域发挥着重要作用。文章聚焦航空发动机整机试验中存在的难点问题,并以其试验特征为基础分析了故障诊断系统设计思路,以模块为单位展开详细论述。

Aeroengines have distinct characteristics of precision and complexity.At first,piston engines were the most common.Now,after a long time of development and progress,the production and manufacturing system has been further improved.Turbofan and turboprop engines have gradually stepped on the historical stage and played an important role in military,civil and other fields.This paper focuses on the difficult problems existing in the whole aeroengine test,analyzes the design idea of fault diagnosis system based on its test characteristics,and discusses it in details in the unit of module.
