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.
Claims13
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.degree. 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 center of gravity of each blade and its associated counterweight is spaced from associated blade axis and lies in a plane passing through the blade axis and which is perpendicular to a chord connecting said blade axis and the blade leading edge.
