| 摘要 |
A wind driven power apparatus for converting wind to mechanical energy is disclosed which includes a fixed axis turbine supported centrally of a fixed air guide defining a plurality of horizontal air passages disposed circumferentially of the turbine and each being adapted to receive an air stream therein coming from a limited range of wind directions and effect accelerated air flow toward the turbine. In one embodiment, an air guide block is disposed circumferentially of the turbine and is rotatable about the axis of the turbine to direct accelerated air flow to the turbine from the windwardly facing ones of the air passages, while in alternative embodiments means are provided for selectively closing off the air passages so that accelerated air flow from selected air passages is directed to the turbine.
