Abstract:
A wind powered machine for producing energy comprisinga support frame,a rotor mounted on the frame for rotation about a substantially horizontal rotor axis, said rotor having a plurality of vanes spaced apart circumferentially about the rotor axis, said rotor having a wind gathering face side and an opposed rear side, and said rotor comprises a pair of laterally spaced opposed enclosing sides and at least one of said vanes on the rotor extends between said sides and has a cross sectional configuration as viewed along a line parallel to the rotor axis which is sinusoidal,an infeed funnel having a wide inlet mouth spaced outwardly from the rotor for receiving a wind at an infeed speed and sides which converge on progressing from the inlet mouth to a smaller wind directing opening adjacent the face side of the rotor to channel said wind to the rotor and increase the speed of the wind channeled to the rotor above the infeed speed,a rear wind deflector member overlying the rear side of the rotor to capture wind passing over the rotor and deflect it downwardly to vanes on the rear side of the rotor,a pivot mounting the rotor and the infeed funnel for rotation about a substantially upright axis, anda positioning fin operatively coupled to the rotor and infeed funnel to be acted upon by the wind to direct the inlet mouth toward an incoming wind.
