Wind powered apparatus having counter rotating blades

摘要

A wind powered apparatus (or wind turbine) comprising a stator blade assembly and a rotor blade assembly wherein said stator blades assembly and said rotor blade assembly have counter rotating blades. Both sets of blades assemblies are connected to a generator and are operable to rotate the stator and rotor thereof in opposite directions relative to one another due to the blade arrangement between assemblies. The blades assemblies comprise a hub connected to an outer ring, wherein said outer ring comprises inward blades. The win turbine, more particularly the blade arrangement co-operates to improve performance of the apparatus by affecting its orientation and the rotational speed of the blades.
