Horizontal axis wind turbine - consists of twisted wind-sock in helically wound form, and includes helical nozzles

摘要

The wind turbine consists of a windsock (1), of a helically wound shape. The wind flows into the helical nozzles, to turn the turbine. The helical windsock may incorporate two separate channels. These channels are identical and are twisted round one another. They may taper from the front end where the wind enters towards the rear end. The windsock is mounted on a mast (2) which allows free swivelling in azimuth through 360 deg. USE/ADVANTAGE - Lightweight wind turbine gives high performance in low winds and operates with very low loading due to centrifugal force.
