Description

Small experimental vertical axis wind turbine (VAWT). This is a Darrieus (lift) type turbine. The blades are about 50cm (18inch) long and made from foam and wood. It turns a small single phase axial flux alternator. The angled blades seem to aid self starting and run very smoothly. More information at http://www.windandwet.com/windturbine/vawt1/vrotor1.php

  • Peter Sharp Added Nice experiment!!! The usual problem with canted blades on a VAWT is that they cause vertical bending oscillations and that leads to fatigue and cracks. Due to their aerodynamic lift, when upwind the blades try to move upward, and when downwind the blades try to move downward.
