Aerodynamic Design and Structural Analysis Procedure for Small Horizontal-Axis Wind Turbine Rotor Blade Dylan Perry This project accomplished two correlated goals of designing a new rotor blade to be used with the Cal Poly Wind Power Research Center, as well as defining the.

    solid wood as a construction material. The aerodynamic analysis is performed implementing a momentum based model on a mathematical computer pro-gram. A three bladed wind turbine is proposed as candidate for further prototype test-ing after evaluating the effect of several parameters in turbine efficiency, torque and acceleration. To design a high-efficiency wind turbine rotor, the accurate numerical prediction for the rotor aerodynamic performances can serve as a quicker and lower-cost alternative as compared to wind tunnel experiments. Past studies applied CFD for wind turbine analysis have provided essential information in the design process of turbine rotor.
