There is a growing market for Wind Energy, where Vertical Axis Wind Turbines (VAWT) are currently overshadowed by Horizontal Axis Wind Turbines (HAWT). While the efficiencies of VAWTs are currently lower than that of their horizontal counterparts, there are significant areas for growth in the VAWT market. The goal of this project was to investigate improvements on VAWTs by designing and developing articulating blades such as those found in Schneider Propellers. The prototype was designed with airfoils with the capability of both articulating and being fixed. In testing it was found that the fixed airfoil design did not start operating at the available wind speeds. At these same wind speeds, it was found that the articulating airfoil design had a maximum efficiency of 8% and produced 7.4 W.
