【Abstract】 The three-dimension finite element model of composite rotor blades for helicopters has been built with APDL language for the first time.Then,using this model,the static strength and dynamic characteristics of rotor blades has been analyzed with ANSYS software package.During the analysis of dynamic characteristics,the influence of aerodynamic force and centrifugal force applying to blades has been totally considered.Furthermore,the resonant chart of rotor blades has been presented in this paper.With this analysis,the composite rotor blade has been produced and successfully used to some unmanned helicopters.更多还原
