ABSTRACT:
A mechanical device which converts the wind energy into rotational mechanical energy has a cross-wind-axis rotor structure, having multiple, orientable blades around its periphery, mounted parallel to the rotor axis. Each blade is interconnected with an orientable stabilizer mounted on the same rotor radial line as the blade, at a smaller radius, so that during rotation, the blade and the stabilizer are able to pivot simultaneously and essentially parallel to each other, in the course of aligning themselves, into a pitch angle, where the opposing pitching moments created by the aerodynamic lift forces over the blade and the stabilizer, equilibrate each other, and where the aerodynamic lift forces are the optimum to induce the necessary torque to spin up the rotor.
