Patent

CA 2646689

A horizontal axis wind turbine apparatus includes a turbine assembly comprising a generator mounted in a housing, a rotor operative to rotate the generator in response to wind forces, and a tail extending rearward from the housing, and a base adapted to be mounted on a tower. The housing is pivotally attached to the base about a horizontal pivot axis oriented substantially perpendicular to a rotational axis of the generator and located rearward of a center of gravity of the turbine assembly such that the housing can pivot upward about the pivot axis from a lowered position to a raised position. A spring is operative to exert a downward bias force on the housing to urge the housing toward the lowered position.
