Wind driven electric generator - has conically narrowing intake leading to rotatable cross:flow impeller with forward curved blades

摘要

The wind-driven electric generator comprises a housing (1) with a conically narrowing intake opening (5) through which the air flow enters and reaches the blades (3) on a rotatable drum (2) driving the generator. A number of these assemblies may be stacked and means may be provided which automatically turn the assembly to face the wind. The blades may be forward-curved and may be provided with louvres which open over the non-productive part of each revolution to reduce resistance. The entire assembly may be mounted on a rail track permitting it to be turned towards the wind.
