| Abstract:According to the characteristics and laws of the effects of foreign object damage（FOD）on high cycle fatigue（HCF）
strength of compressor blades，the research status at home and abroad and the expected development trend are summarized. The effects of
FOD characteristics on the HCF strength of compressor blades，the effects of residual stress and laser shock peening on the strength of
HCF，the numerical simulation of FODed blades，and the life model of FODed blades are reviewed. The analysis shows that FOD affects
the HCF strength of compressor blades in many ways and follows some common rules，such as，the impact angle of 60 ° is dangerous，the
increase of impact depth will reduce the strength of the blade，and the tensile residual stress can improve the fatigue strength of the blade，
appropriate surface treatment can also improve the strength of the blade. There are some problems in the existing FOD research on the HCF
strength of compressor blades：The experimental methods need to be further improved，the theoretical model needs to be more thoroughly
studied，and the laws of the influence of residual stress on the HCF strength of compressor blades are not uniformed. |
