48" Wind Razor Wings for Vertical Axis Wind Turbine
Our Wind razor wings use the NACA 0020 airfoil. This airfoil was selected because when used for a VAWT it produces high lift, has low drag and is easily self-starting. The low drag generates higher rotational speeds which improves the efficiency. The surface is turbulated to help reduce airflow separation and increase the lifting zone of the wings circular path. The wing skin is a extruded from a tough, light weight, UV stabilized, high impact synthetic plastic polymer. A 1-3/8" diameter, .060" wall thickness, tubular steel spar is used to provide the structural strength and stiffness as well as secure and robust mounting.
