Description

EN: Savonius wind turbines are a type of vertical-axis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft. The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems.

FR: Le rotor de Savonius est une éolienne à axe vertical. Elle a été inventée par l'ingénieur finlandais Sigurd Savonius en 1924 et a été brevetée en 1929.
Rotor de Savonius
Le fonctionnement du rotor de Savonius est basé sur un couple aérodynamique induit par la déflexion de l'écoulement sur les pales.

Just insert the rollerblade bearing ZZ809 in the support.
Insérez le roulement de roller ZZ809 dans le support.

It works perfectly at really low wind speed.
New version soon, enjoy! :)
