对外物损伤(FOD)对航空发动机风扇/压气机叶片高循环疲劳(HCF)性能影响的国内外研究进行了综述和分析,介绍了美、英等国通过实施涡轮发动机HCF研究计划在FOD对叶片HCF性能的影响研究方面所取得的进展和成果,总结了中国近年来对FOD问题的研究内容,指出了中国该项技术研究的不足和差距,并对需要进一步深入研究的关键技术问题提出了建议。
The domestic and foreign studies on the effect of foreign body damage (FOD) on the performance of aero-engine fan / compressor blades in high cycle fatigue (HCF) are reviewed and analyzed. The introduction of the HCFC research program of the turbine engine in the United States, HCF performance of the research progress made and achievements made, summed up China in recent years on the FOD research content, pointed out the lack of technology research in China and the gap, and the need for further study of the key technical issues are proposed .
