報告摘要：
Composite blades can significantly improve the aeroelastic stability, vibration characteristic and aerodynamic efficiency of rotors and have been widely used in helicopters. All of the existing aeroelastic analyses of composite blades are based on the moderate deflection beam theory and use an order scheme to neglect higher-order terms. However, with the development of novel rotor concepts, rotor blades may produce large deflections, which makes the analyses based on the moderate deflection beam theory not applicable anymore. Therefore, it is necessary to developan aeroealstic modeling and aeroelasticanalysis method for composite blades with large deflections. In this presentation, an accurate and effective aeroelastic modeling and aeroelastic response analysis method suitable for composite blades undergoing large deflections is introduced. The method is developed by combining the geometrically exact nonlinear structural model and unsteady aerodynamic model,and its accuracy is verified by the correlations between the predicted results and experimental data.
