Vertical axis portable wind-powered generator - makes use of flaps with variable profile hinged sections

摘要

The windmill has a vertical axis (1) about which moves a rotatable profiled grid (2) with a movable flap (3) attached. Its rotary axis is parallel to the main axis. The profile of the flap is variable by means of a hinge (5) the angle of which can be controlled to suit prevailing aerodynamic conditions. USE/ADVANTAGE - Vertical axis wind powered generator with a variable 'sail' profile suitable for installation on a roof or at a camp site.
