Abstract

A wind turbine having a frame supporting a pair of rotatable axels, each having a pair of sprockets disposed on opposed ends thereof, the axels being parallel and vertically spaced from one another. Endless chains are deployed about vertically aligned sprockets on the upper and lower axels. Pivotally coupled between the chains in parallel relation is a plurality of regularly-spaced airfoils. The frame supports cowling members for directing an incident wind stream across the airfoils, producing a lift force on leading airfoils and a downward force on trailing airfoils to thereby rotate the axels and drive a generator. Cam followers affixed to the airfoils cooperate with stationary cams to steer the airfoils as they pass about the sprockets. The airfoils further include a wing-like structure with a shiftable leading edge profile to create lift forces on the leading airfoils and changing to downward forces on the trailing airfoils as they move from a leading to a trailing position.
