ABSTRACT:
Wind energy conversion apparatus comprises vertical endless travelling belt means and a plurality of inter-spaced hydrodynamic foil members mounted thereon. Passage of fluid, i.e. wind, over the foil members creates lift forces thereon serving to drive the endless belt means about belt circulating parts. The foil members may have a fixed angle of incidence with respect to the belt runs i.e. between the circulating parts at the top and bottom of the endless belt means; or they may be of variable pitch. In one embodiment the belt means comprises two separate endless belts the foils are carried on arms which have pivotal connections with both belts; and a tension spring connects the belts. A belt circulating part, the lower wheel is coupled to a rotary load, an electric generator. Aerodynamic lift on the foils drives the belt and, by the spring connection, the belt and the rotary load. The foil angle of incidence is determined by the lift and the spring reaction.
