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.
A rotatable device powered by a moving fluid such as water or air, comprising a generally cylindrical rotor disposed for rotation about a vertical axis, a plurality of blades mounted on said rotor adjacent its periphery for free unrestrained rotation, in normal usage, through 360°about essentially vertical axes passing through said blades, each of said blades having a symmetrical aerodynamic profile and a leading edge remote from the blade axis, a counterweight rigid with each of said blades, said blades and counterweight being constructed such that the ...
