ABSTRACT:
A rotary device driven by a moving fluid, such as water or air, for generating a rotary movement comprises a cylindrical or frusto-conical rotor having a vertical axis, the rotor having a plurality of identical blades distributed around the periphery of the rotor, each blade having a symmetrical aerodynamic profile and being mounted so as to freely rotate about a substantially vertical axis parallel to its leading edge. The device may be used to power a screw driven boat, a wheeled vehicle or other machinery.
