英文摘要： The project is to study optimization design of shape and performance for wind turbine blades based on the aeroelastic stability of rotary rotors which have influence on aerodynamic characteristics and design condition of wind turbine blades. Using the functional analysis theory and series form, the integration expression and convergence of shape function for wind turbine blades will be introduced. With the aerodynamics, structural and elastic dynamics, the coupling essence between the aeroelastic stability of rotary rotors and shape function of wind turbine blades will be investigated. Then using multidisciplinary optimization method, the optimization design model of wind turbine baldes including of aeroelastic stability of rotary rotor and functional integration expression will be presented and resolved by searching optimization strategy and arithmetic. Finally, the independent and innovative design method for wind turbine blades which is different with other traditionary design method will be introduced. The new and efficient blades will be found to increase the output power of wind turbines and reduce the cost of wind power. The aerodynamic and structural characteristics of design blades will be validated with wind tunnel test. The achievements of this project not only have very important significance to impr
