Directionally stabilized wind turbine
Patent
·
OSTI ID:5166861
A downwind rotor wind turbine has a rotor with a horizontal axis carried for operation on the downwind end of a pod or nacelle pivotally mounted on a vertical pivot located upwind of the rotor on the top of an elevated structure. Each blade is provided at its tip with a tip plate. The tip plates have a surface area large enough to provide an aerodynamic force on the rotor when the wind shifts away from the rotational axis of the rotor such that a restoring moment is furnished about the turbine pivot to turn the turbine automatically back into the wind.
