Rotor development for a small wind turbine (200 watts) through local technology implementation

Abstract:

Colombia has a wind potential of nearly 21,000 MW. Nevertheless, the technology used so far is totally foreign and the knowledge currently available in Colombia for producing wind turbines at an industrial level is not sufficient. This article describes the first development stage for lowpower (200 W) wind turbine rotors, and presents the selection process of the aerodynamic parameters involved in the design and implementation of two rotors with different profiles (NACA 4412 and NACA 2509). It includes the corresponding mechanical modeling, the aerodynamic and structural analysis of the two rotors, as well as an energy efficiency comparison under laboratory conditions.
