Savonius wind turbine

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

Savonius Wind Turbine Design

A Savonius wind turbine is what's known as a VAWT kind of generator or vertical axis wind turbine generator It operates in similar fashion to a cup anemometer which is a device that measures the velocity of the wind so it's also categorized as a drag-type VAWT

Cardboard Savonius Wind Turbine

Savonius wind turbines are a type of turbines which are used for catching wind power The Savonius wind turbines are drag-type consisting of either 2 or 3 scoops The turbines curvature makes the machine to experience little drag when the machine is moving in the opposite direction to that of the wind Much of the Savonius rotor is placed very near the ground and this in turn reduces the overall energy produced

Vertical axis wind turbine

A vertical-axis wind turbines (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine This arrangement allows the generator and gearbox to be located close to the ground facilitating service and repair

Savonius Principle

Savonius Wind Turbine Savonius turbines are one of the simplest turbines Aerodynamically they are drag-type devices consisting of two or three scoops Looking down on the rotor from above a two-scoop machine would look like an S shape in cross section Because of the curvature the scoops experience less drag when moving against the wind

vertical axis wind turbine

Vertical axis wind turbines (VAWTs) have an axis of rotation that is vertical and so unlike the horizontal wind turbines they can capture winds from any direction without the need to reposition the rotor when the wind direction changes (without a special yaw mechanism)

How Efficient are Vertical Axis Wind Turbines compared to

Oct 05 2010Vertical Axis Wind Turbines around 10% (though an excellent design could reach near 15%) The bottom line is that while vertical axis wind turbines can make a great do-it-yourself project and on a small scale they can even be a worthwhile project -- in reality they are far less efficient than horizontal axis wind turbines
