The Enhanced Airfoil Blade Modification by Asterion Technologies was tested along side its corresponding Baseline Airfoil at the Fluid Mechanics Research Laboratory at the University of Waterloo
The results of these tests show that the enhanced airfoil blade design is able to significantly decrease drag under practical wind conditions while maintaining / increasing the lift force.
This results in more laminar flow and a better overall aerodynamic performance, shown by the increases in the Lift/Drag ratios.

A Visualization of the Forces on an Wind Turbine Blade
Because of the orientation of wind turbine blades with incoming winds, increases in lift/drag at greater angles of relative wind speed will result in significantly larger tangential forces, increasing the overall turbine efficiency.
Using the test data, the effect that the Enhanced Airfoil Blade Modification has on the tangential force coefficient with respect to different angles of relative wind speeds is shown on the left.
While more research is needed, there is a definitive trend that shows that our technology has the ability to greatly improve wind turbine power density along the blades.
