摘要
航空燃气涡轮发动机技术是一个国家工业水平和科技实力的综合体现,故障诊断技术是航空发动机安全、经济运行的重要保障,也是衡量其先进性的重要指标之一。由于航空发动机结构复杂、系统集成度高、服役环境恶劣、工作状态多变,同时存在在线测试条件有限、诊断信息量不易保障等制约,故障诊断面临较多挑战。本文从气路分析与性能评价、机械系统故障诊断和多参量信息融合3个方面对国内外航空发动机故障诊断技术进行梳理,剖析存在的主要问题和挑战,并对未来发展趋势进行展望。
Gas turbine engine is a comprehensive embodiment of the level of national science,technology and industry.Fault diagnosis is an important guarantee for its safe and reliable operation and an essential indicator of engine advancement.However,due to the complicated structure,highly integrated system,harsh service environment,variable mission profiles,the constraints of limited online testing conditions,and the poor supportability of diagnostic information acquisition,the fault diagnosis for aeroengine faces multiple challenges.In this paper,the research status in China and abroad is firstly reviewed and analyzed from three aspects:gas path analysis and performance evaluation,mechanical fault diagnosis and information fusion.Then,the exciting key problems and challenges in the current research are pointed out.Finally,the future development trends are discussed.
