SAVONIUS TURBINE

OPTIONS: VERTICAL AXIS TURBINES

This turbine belongs to the category of resistance turbines, where the resistance to the force of the wind causes the rotation of the axis.

The greatest handicap of vertical axis turbines, which limits their performance, consists in the fact that a part of them will rotate in the opposite direction to the wind and a part in favor.

The Savonius turbine, to avoid this problem, is made of two half-shells (in the simplest version) which are not joined to the rotor of the turbine, but arranged so that a part of the half-shells lets the thrust air flow also through the upwind part.
