초록 ▼

A machine for converting wind energy into electrical energy comprising in combination a housing; propellers at the forward and rearward ends of the housing mounted on shafts for rotation upon a common horizontal axis of rotation; post means supporting a central extent of the housing for rotation in a horizontal plane to face into the wind; an alternator within the housing formed of a power take off member coupled to one shaft and a rotor coupled to another shaft for counter rotating when the propellers rotate for thereby generating electricity; centrifugal pitch control mechanisms for varying the pitch of the propellers as a function of the propeller speed; transmission mechanisms for varying the speed of rotation of the rotor and power take off member as a function of the wind speed; brake mechanisms for proportionately restraining the propellers against rotation; and an aerogovernor operatively coupled with the brake mechanisms for control thereof in response to the speed of the wind as determined by the aerogovernor.

A machine for converting wind energy into electrical energy comprising in combination: a housing; propellers of opposite pitch, respectively at the extreme foreward and rearward ends of the housing mounted on separate shafts for rotation upon a common horizontal axis of rotation but separated by the length of the housing; post means supporting a central extent of the housing for turntable like rotation in a horizontal plane to allow the housing to be oriented parallel to the wind; an alternator within the housing including a winding part called the power generator housing coupled to the larger diameter propeller\s shaft and a field part called the rotor coupled to the smaller diameter propeller\s shaft for counter-rotating when the propellers rotate propelled by the wind thereby generating electricity; coaxial slip ring means in the alternator which in cooperation with spring loaded carbon brushes and wires completes the circuit for transmission of current between the alternator and exterior thereof; centrifugal pitch control mechanisms located at the extreme outboard end of the propellers for varying the pitch of the propellers as a function of the windspeed to obtain maximal electrical output of the alternator for given wind conditions; transmission mechanisms for varying the speed of rotation of the rotor and the power generator housing by centrifugal force as a function of the windspeed; brake mechanisms for proportionately restraining the propellers against over rotation and stoppage in case of excessively high wind; a protective aerogovernor operatively coupled by hydraulic means to trigger means to over ride pitch control mechanisms for full feathering of the propellers; the brake means are capable of slowing and stopping the propellers in response to excessively high speed of the wind as determined by the aerogovernor; the propeller blade pitch control trigger means over ride mechanism, which is capable of automatic protection of the slowed or stopped and otherwise broad aspect of the propeller blades, functions to turn the propeller blades edgewise or parallel to the wind in high wind speed conditions.
