The payback of wind turbines is decreasing, but the technological developments required to increase efficiency are progressing in micro steps.
Serrations and 'back flow' flaps on the wings of wind turbines enhance the aerodynamic stream. The technology is based on an bionic principle: birds' feathers rising at a high attack angle of the wind increase ascending forces while reducing turbulence. WTS addresses operators of wind parks interested in enhancing efficiency and profit. Firstly as a retrofit solution for existing plants, later as an add-on in cooperation with producers of wind turbines (e.g. licensing).
• 3-6% increased efficiency.
• Improved flow profile relieves wings and bearings.
• Noise reduction (expected noise reduction of approx. 1-3 dB).
• Payback within 2 years.
