Paper Abstract
The primary purpose of this research effort is to propose a novel efficiency boosting design feature in a drag type
vertical axis wind turbine (VAWT), explore practicality through design and fabrication, and test the viability of the
design through wind tunnel experiments. Using adaptive control surface design and an improved blade shape can be very
useful in harnessing the wind's energy in low wind speed areas. The new design is based on a series of smaller blade
elements to make any shape, which changes to reduce a negative resistance as it rotates and thus maximizing the useful
torque. As such, these blades were designed into a modified Savonius wind turbine with the goal of improving upon the
power coefficient produced by a more conventional design. The experiment yielded some positive observations with
regard to starting characteristics. Torque and angular velocity data was recorded for both the conventional configuration
and the newly built configuration and the torque and power coefficient results were compared.
