About Us

EdgeWind was spun out of Edge Aerodynamix to develop wind power applications of the Conformal Vortex Generator (CVG) tape technology that they developed for aircraft winds and helicopter rotor blades. This CVG technology increases annual wind turbine energy production, provides protection from erosion and impacts, reduces drag caused by leading edge erosion, reduces startup speeds, reduces vibrations, and increases gearbox life. NREL is currently testing the technology on several megawatt scale turbines.

Edge Aerodynamic has developed a Conformal Vortex Generator (CVG) technology that improves the aerodynamic efficiency of aircraft wings and rotor blades. The company has received a Supplemental Type Certificate (STC) from the FAA authorizing the CVG modification to Boeing 737 series aircraft. The company is currently going through the STC testing process on other Boeing and Airbus aircraft models. For a large airline, the Edge CVG technology means hundreds of millions of dollars in annual fuel cost savings without downtime for the aircraft modifications.


Conformal Vortex Generators and Lift Enhancing Tabs

Conformal Vortex Generators



The Conformal Vortex Generator (CVG) is placed on the leading edge of the wing and other surfaces and produces pairs of counter-rotating vortices in the lower boundary layer. These vortices reduce shock wave induced vibration, increase attached free stream flows, energize the boundary layer, and create suction on the boundary layer.

Lift Enhancing Tabs



Lift enhancing tabs reduce cut-in wind speed (increases production), increases torque (improves the performance curve across all wind speeds), reduces tip loading and out of plane bending, and relieves root load reducing gear box stress. CVG and Tabs are placed as follows:



Increased KWH Production

Turbine owners benefit from increased power generation across all wind speeds, increased torque for governed RPM, and lower cut-in speeds. The CVG tape also repairs damage from turbine blade erosion and restores performance



Reduced Tubine Damaged & Erosion



The CVG material provides structural protection of the blades, protecting against blade tip erosion from icing, storms, and contaminants such as salt. In addition, the reduction in vibration extends the life of turbine gear boxes and reduces the need for expensive gear box repairs, replacement, and downtime from failures.
