摘要：This study seeks to optimize a fixed-pitch fixed speed (FPFS) wind turbine blade’s performance using the chord, twist and the use of 3 different airfoils with varying relative thickness as design variables for the maximization of the Annual Energy Production for the wind profile of Roswell NM. A baseline design of the blade starts with a replica of the Phase VI blade utilized in a NASA-Ames experiment and a Matlab script utilizes the Blade Element Momentum Theory (BEM) for the aerodynamic analysis. The SQP method for Local Search are used to exploit the model utilizing the Phase VI design as a starting point which contains the S809 airfoil with a 0.21 relative thickness for the complete blade. Optimization results reduced the relative thickness of the airfoils to 0.17 and an increase of 36% in energy production was observed using this method .
