Abstract： Rotor,a key component of the helicopter,provides lift and flight control,and failure occurrence of which could lead to disastrous accidents.As bird strike is the typical accident for helicopters resulting from its low altitude flight,it is necessary to investigate the dynamic process of bird strike and its damage failure behavior.Based on the requirements of airworthiness regulations and national military standards for helicopters,this paper first analyzes the characteristics of bird strike on helicopter rotor and the significance of relevant research.Subsequently,the investigations on experiments,model characterization methods and numerical simulation technologies of bird strike on helicopter rotor are reviewed and summarized.The bird strike resistance optimization methods and prevention strategies of helicopter rotor are also introduced.Finally,the future developments of research onbird strike of helicopter rotor are predicted.This review would provide technical supports for engineering design of helicopter rotor.
