Small Power Wind Turbine with Vertical Axle

Abstract

To increase the conversion efficiency of wind energy at speeds a new wind working element has been designed, based on combined effect of the Darrieus and Helical rotors. It has the shape of Darreus turbine with aerodynamic profile of blades in normal section.

Pentru a mari eficienta de conversie a energiei eoliene la viteze V=2...5 m/s a fost elaborat un organ de lucru nou bazat pe actiunea combinata a turbinelor Darreus si elicoidala. Palele turbinei Darreus au profil aerodinamic în sectiune normala.
