Golden ratio axial flow apparatus

摘要

A fluid flow rotary driven apparatus includes a support having an axis of rotation and a plurality of elongate, curved rotor wings attached to and extending outwardly from the support. Each wing is attached to the support at an inner end and projects outwardly in a direction transverse to the axis of rotation to a distal end. Each wing includes a convex surface defining a plurality of logarithmic spiral line segments interconnecting the inner and outer ends. Each spiral line segment extends completely within a respective plane transverse to the axis of rotation. The wings are responsive to a fluid flow across the outer surface of the wings for driving the support to turn about the axis of rotation. A rotary transmission device is operably connected to the support and responds to turning of the support for producing an energy output.

1. A fluid flow rotary driven apparatus comprising:
a rotor including a support section that has an axis of rotation extending therethrough and a plurality of elongate curved rotor wings attached to said support section and extending longitudinally outwardly in a spiral configuration from said support section, each said wing having inner and outer ends at respective longitudinal ends thereof and a pair of opposing longitudinal edges that interconnect said inner and outer ends, each said wing being attached to said support section at said inner end of said wing and projecting longitudinally outwardly to said outer end of said wing in a direction from said inner end to said outer end that is transverse to said axis of rotation, each said wing including a convexly curved outer surface defined by a plurality of logarithmic spiral line segments, at least one said logarithmic spiral line segment originating from a point on said axis of rotation and extending longitudinally across said wing to interconnect said inner and outer ends of said wing, each said logarithmic spiral line segment extending in its entirety within a single respective plane outwardly from said axis of rotation, said convexly curved surface further being defined by circularly curved arcs extending between and interconnecting said opposing longitudinal edges of said wing and intersecting said logarithmic spiral line segments, at least one said logarithmic spiral line segment in each said wing being longer than each said arc in said wing; said wings being responsive to a fluid flow across said outer surfaces of said wings for driving said support section to turn about said axis of rotation; said outer end of each said wing and an inner point on at least one said logarithmic spiral line segment being interconnected by a straight line that intersects said axis of rotation such that said outer end and said inner point are located on opposite sides of said axis of rotation and the fluid flow across said wings produces a leverage arm along said straight line that facilitates turning of said rotor and rotation of said wings; and a rotary transmission device operably interconnected to said support section and responsive to turning of said support section for producing a selected form of energy output.
